【Shiro】Springboot 关于 Shiro 权限配置 以及 相关问题解决

1、权限配置首先涉及到用户、权限、角色三张表，三张表的关系为用户与角色为一对多，角色与权限为一对多

2、配置shiro的相关目录

3、引入shiro相关依赖

 
        
        
            org.apache.shiro
            shiro-core
            1.3.2
        
        
        
            org.apache.shiro
            shiro-spring
            1.3.2
        

4、配置shiro对应认证登录或授权，添加AuthRealm.class

• 下面的MyException是我设置的自定义异常处理

import com.cqjtu.platform.dao.ResourceDao;
import com.cqjtu.platform.entity.Role;
import com.cqjtu.platform.entity.User;
import com.cqjtu.platform.enums.ExceptionEnums;
import com.cqjtu.platform.exception.MyException;
import com.cqjtu.platform.service.RoleService;
import com.cqjtu.platform.service.UserService;
import org.apache.shiro.authc.*;
import org.apache.shiro.authz.AuthorizationInfo;
import org.apache.shiro.authz.SimpleAuthorizationInfo;
import org.apache.shiro.realm.AuthorizingRealm;
import org.apache.shiro.subject.PrincipalCollection;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.util.CollectionUtils;
import org.springframework.util.StringUtils;

import java.util.*;

/**
 * @author pengyangyan
 */
public class AuthRealm extends AuthorizingRealm {

    @Autowired
    private UserService userService;
    @javax.annotation.Resource
    private ResourceDao resourceDao;
    @Autowired
    private RoleService roleService;

    /**
     * 授权
     * @param principalCollection
     * @return
     */
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
        User user = (User) principalCollection.fromRealm(this.getClass().getName()).iterator().next();
        Set permissionSet = new HashSet<>();
        SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();
        Role role = roleService.selectByKey(user.getRoleId());
        List roleResource = resourceDao.findRoleResource(user.getRoleId(),null);
        if (!CollectionUtils.isEmpty(roleResource)){
            roleResource.forEach(v->{
                if (!StringUtils.isEmpty(v.getPermission())){
                    permissionSet.add(v.getPermission());
                }
            });
        }
        info.addRole(role.getRoleName());
        info.setStringPermissions(permissionSet);
        return info;
    }

    /**
     * 认证登录
     * @param authenticationToken
     * @return
     */
    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken){
        UsernamePasswordToken usernamePasswordToken = (UsernamePasswordToken) authenticationToken;
        String account = usernamePasswordToken.getUsername();
        User user = userService.findByAccount(account);
        if (Objects.isNull(user)){
            throw new MyException(ExceptionEnums.ACCOUNT_IS_NOT_EXIT);
        }
        return new SimpleAuthenticationInfo(user, user.getPassword(), this.getClass().getName());
    }
}

5、密码是否匹配的相关逻辑可以自定义，创建CredentialMatcher.class

import com.cqjtu.platform.utils.MD5Utils;
import org.apache.shiro.authc.AuthenticationInfo;
import org.apache.shiro.authc.AuthenticationToken;
import org.apache.shiro.authc.UsernamePasswordToken;
import org.apache.shiro.authc.credential.SimpleCredentialsMatcher;

/**
 * @author pengyangyan
 */
public class CredentialMatcher extends SimpleCredentialsMatcher {
    @Override
    public boolean doCredentialsMatch(AuthenticationToken token, AuthenticationInfo info) {
        UsernamePasswordToken usernamePasswordToken = (UsernamePasswordToken) token;
        String password = new String(usernamePasswordToken.getPassword());
        String dbPassword = (String) info.getCredentials();
        return this.equals(MD5Utils.encrypt(usernamePasswordToken.getUsername(),password),dbPassword);
    }
}

MD5Utils为密码md5加密工具
 

import org.apache.shiro.crypto.hash.SimpleHash;
import org.apache.shiro.util.ByteSource;

/**
 * @author pengyangyan
 */
public class MD5Utils {

    protected MD5Utils(){

    }

    private static final String SALT = "platform";

    private static final String ALGORITH_NAME = "md5";

    private static final int HASH_ITERATIONS = 2;

    public static String encrypt(String pswd) {
        return new SimpleHash(ALGORITH_NAME, pswd, ByteSource.Util.bytes(SALT), HASH_ITERATIONS).toHex();
    }


    public static String encrypt(String username, String pswd) {
        return new SimpleHash(ALGORITH_NAME, pswd, ByteSource.Util.bytes(username.toLowerCase() + SALT),
                HASH_ITERATIONS).toHex();
    }

}

6、创建ShiroService动态获取登录角色的权限，创建ShiroService.class

package com.cqjtu.platform.shiro;

import com.cqjtu.platform.entity.Resource;
import com.cqjtu.platform.entity.User;
import com.cqjtu.platform.service.ResourceService;
import com.cqjtu.platform.service.UserService;
import lombok.extern.slf4j.Slf4j;
import org.apache.shiro.SecurityUtils;
import org.apache.shiro.mgt.RealmSecurityManager;
import org.apache.shiro.spring.web.ShiroFilterFactoryBean;
import org.apache.shiro.subject.SimplePrincipalCollection;
import org.apache.shiro.subject.Subject;
import org.apache.shiro.web.filter.mgt.DefaultFilterChainManager;
import org.apache.shiro.web.filter.mgt.PathMatchingFilterChainResolver;
import org.apache.shiro.web.servlet.AbstractShiroFilter;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.util.CollectionUtils;
import org.springframework.util.StringUtils;
import tk.mybatis.mapper.entity.Example;

import java.util.LinkedHashMap;
import java.util.List;
import java.util.Map;

/**
 * @author pengyangyan
 */
@Slf4j
@Service
public class ShiroService {

    @Autowired
    private ResourceService resourceService;
    @Autowired
    private UserService userService;

    /**
     * 初始化权限
     */
    public Map loadFilterChainDefinitions() {
        /*
            配置访问权限
            - anon:所有url都都可以匿名访问
            - authc: 需要认证才能进行访问（此处指所有非匿名的路径都需要登陆才能访问）
            - user:配置记住我或认证通过可以访问
         */
        LinkedHashMap filterChainDefinitionMap = new LinkedHashMap();
        // 配置退出过滤器,其中的具体的退出代码Shiro已经替我们实现了
        filterChainDefinitionMap.put("/api/user/loginOut", "anon");

        filterChainDefinitionMap.put("/error", "anon");

        filterChainDefinitionMap.put("/loginUser", "anon");

        //设置文件上传为匿名访问
        filterChainDefinitionMap.put("/api/uploadFile/upload", "anon");

        filterChainDefinitionMap.put("/login", "anon");
        //未授权跳转url
        filterChainDefinitionMap.put("/unauthorized","anon");
        // 加载数据库中配置的资源权限列表
        List resourcesList = resourceService.listUrlAndPermission();
        for (Resource resource : resourcesList) {
            if (!StringUtils.isEmpty(resource.getUrl()) && !StringUtils.isEmpty(resource.getPermission())) {
                String permission = "perms[" + resource.getPermission() + "]";
                filterChainDefinitionMap.put(resource.getUrl(), permission);
            }
        }
        // 不存在什么特别关键的操作，所以直接使用user认证，支付相关用authc
        filterChainDefinitionMap.put("/**", "user");
        return filterChainDefinitionMap;
    }

    /**
     * 重新加载权限
     */
    public void updatePermission() {
        ShiroFilterFactoryBean shirFilter = SpringContextHolder.getBean(ShiroFilterFactoryBean.class);
        synchronized (shirFilter) {
            AbstractShiroFilter shiroFilter = null;
            try {
                shiroFilter = (AbstractShiroFilter) shirFilter.getObject();
            } catch (Exception e) {
                throw new RuntimeException("get ShiroFilter from shiroFilterFactoryBean error!");
            }

            PathMatchingFilterChainResolver filterChainResolver = (PathMatchingFilterChainResolver) shiroFilter.getFilterChainResolver();
            DefaultFilterChainManager manager = (DefaultFilterChainManager) filterChainResolver.getFilterChainManager();

            // 清空老的权限控制
            manager.getFilterChains().clear();

            shirFilter.getFilterChainDefinitionMap().clear();
            shirFilter.setFilterChainDefinitionMap(loadFilterChainDefinitions());
            // 重新构建生成
            Map chains = shirFilter.getFilterChainDefinitionMap();
            for (Map.Entry entry : chains.entrySet()) {
                String url = entry.getKey();
                String chainDefinition = entry.getValue().trim().replace(" ", "");
                manager.createChain(url, chainDefinition);
            }
        }
        log.info("用户权限重新加载成功！！");
    }

    /**
     * 重新加载用户权限
     *
     * @param user
     */
    public void reloadAuthorizingByUserId(User user) {
        RealmSecurityManager rsm = (RealmSecurityManager) SecurityUtils.getSecurityManager();
        AuthRealm shiroRealm = (AuthRealm) rsm.getRealms().iterator().next();
        Subject subject = SecurityUtils.getSubject();
        String realmName = subject.getPrincipals().getRealmNames().iterator().next();
        SimplePrincipalCollection principals = new SimplePrincipalCollection(user.getId(), realmName);
        subject.runAs(principals);
        shiroRealm.getAuthorizationCache().remove(subject.getPrincipals());
        subject.releaseRunAs();

        log.info("用户[{}]的权限更新成功！！", user.getAccount());

    }

    /**
     * 重新加载所有拥有roleId角色的用户的权限
     * @param roleId
     */
    public void reloadAuthorizingByRoleId(Integer roleId) {
        Example example = new Example(User.class);
        Example.Criteria criteria = example.createCriteria();
        criteria.andEqualTo("roleId",roleId);
        List userList = userService.selectByExample(example);
        if (CollectionUtils.isEmpty(userList)) {
            return;
        }
        for (User user : userList) {
            reloadAuthorizingByUserId(user);
        }
    }



}

7、接下来就是配置shiro的所有Bean，也是将前面配置的内容注入到shiro的配置当中。创建ShiroConfiguration.class

import org.apache.shiro.cache.MemoryConstrainedCacheManager;
import org.apache.shiro.codec.Base64;
import org.apache.shiro.mgt.SecurityManager;

import org.apache.shiro.spring.LifecycleBeanPostProcessor;
import org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor;
import org.apache.shiro.spring.web.ShiroFilterFactoryBean;
import org.apache.shiro.web.mgt.CookieRememberMeManager;
import org.apache.shiro.web.mgt.DefaultWebSecurityManager;
import org.apache.shiro.web.servlet.SimpleCookie;
import org.springframework.aop.framework.autoproxy.DefaultAdvisorAutoProxyCreator;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.DependsOn;

import java.util.Map;

/**
 * @author pengyangyan
 */
@Configuration
public class ShiroConfiguration {

    @Autowired
    private ShiroService shiroService;

    @Bean
    public ShiroFilterFactoryBean shiroFilterFactoryBean(@Qualifier("securityManager") SecurityManager securityManager){
        ShiroFilterFactoryBean bean = new ShiroFilterFactoryBean();
        bean.setSecurityManager(securityManager);
        //登录界面url
        bean.setLoginUrl("/api/user/login");
        //登陆后跳转成功url
        bean.setSuccessUrl("/success");
        //未授权跳转url
        bean.setUnauthorizedUrl("/unauthorized");
        // 配置数据库中的resource
        Map filterChainDefinitionMap = shiroService.loadFilterChainDefinitions();
        bean.setFilterChainDefinitionMap(filterChainDefinitionMap);
        return bean;

    }

    @Bean("securityManager")
    public SecurityManager securityManager(@Qualifier("authRealm") AuthRealm authRealm,@Qualifier("cookieRememberMeManager") CookieRememberMeManager cookieRememberMeManager){
        DefaultWebSecurityManager manager = new DefaultWebSecurityManager();
        manager.setRealm(authRealm);
        manager.setRememberMeManager(cookieRememberMeManager);
        return manager;
    }

    @Bean("cookieRememberMeManager")
    public CookieRememberMeManager cookieRememberMeManager(@Qualifier("simpleCookie") SimpleCookie simpleCookie){
        CookieRememberMeManager manager = new CookieRememberMeManager();
        manager.setCipherKey(Base64.decode("cGxhdGZvcm0AAAAAAAAAAA=="));
        manager.setCookie(simpleCookie);
        return manager;
    }

    @Bean("simpleCookie")
    public SimpleCookie simpleCookie(){
        SimpleCookie simpleCookie = new SimpleCookie("rememberMe");
        simpleCookie.setHttpOnly(true);
        simpleCookie.setMaxAge(7*24*60*60);
        return simpleCookie;
    }

    @Bean("authRealm")
    public AuthRealm authRealm(@Qualifier("credentialMatcher") CredentialMatcher credentialMatcher){
        AuthRealm authRealm = new AuthRealm();
        authRealm.setCacheManager(new MemoryConstrainedCacheManager());
        authRealm.setCredentialsMatcher(credentialMatcher);
        return authRealm;
    }

    /**
     * 凭证验证器
     * @return
     */
    @Bean("credentialMatcher")
    public CredentialMatcher credentialMatcher(){
        return new CredentialMatcher();
    }


    /**
     *  开启shiro aop注解支持.
     *  使用代理方式;所以需要开启代码支持;
     * @param securityManager
     * @return
     */
    @Bean
    public AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor(@Qualifier("securityManager") SecurityManager securityManager) {
        AuthorizationAttributeSourceAdvisor advisor = new AuthorizationAttributeSourceAdvisor();
        advisor.setSecurityManager(securityManager);
        return advisor;
    }

    @Bean
    @DependsOn("lifecycleBeanPostProcessor")
    public DefaultAdvisorAutoProxyCreator defaultAdvisorAutoProxyCreator() {
        DefaultAdvisorAutoProxyCreator creator = new DefaultAdvisorAutoProxyCreator();
        creator.setProxyTargetClass(true);
        return creator;
    }

    @Bean(name = "lifecycleBeanPostProcessor")
    public static LifecycleBeanPostProcessor getLifecycleBeanPostProcessor() {
        return new LifecycleBeanPostProcessor();
    }
}

问题解决

1、如果项目为前后端分离，则会涉及到相关的跨域问题，如Cros跨域所以接下来会涉及项目跨域允许配置的相关过滤器

•      CorsFilter,配置允许跨域

     

import javax.servlet.*;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;

/**
 * @author pengyangyan
 */
public class CorsFilter implements Filter {
    @Override
    public void init(FilterConfig filterConfig) throws ServletException {

    }

    @Override
    public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {
        servletRequest.setCharacterEncoding("utf-8");
        HttpServletResponse httpServletResponse = (HttpServletResponse) servletResponse;
        HttpServletRequest httpServletRequest = (HttpServletRequest) servletRequest;
        //是否支持cookie跨域
        httpServletResponse.setHeader("Access-Control-Allow-Credentials","true");

        //指定允许其他域名访问

        httpServletResponse.setHeader("Access-Control-Allow-Origin", httpServletRequest.getHeader("Origin"));


        //响应头设置
        httpServletResponse.setHeader("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept,client_id, uuid, Authorization,user-agent,x-csrftoken");

        // 设置过期时间
        httpServletResponse.setHeader("Access-Control-Max-Age", "3600");

        //响应类型
        httpServletResponse.setHeader("Access-Control-Allow-Methods", "POST, GET, PUT, OPTIONS, DELETE");

        // 支持HTTP1.1.
        httpServletResponse.setHeader("Cache-Control", "no-cache, no-store, must-revalidate");

        // 支持HTTP 1.0. 
        httpServletResponse.setHeader("Pragma", "no-cache");

        httpServletResponse.setHeader("Allow","GET, HEAD, POST, PUT, DELETE, TRACE, OPTIONS, PATCH");


        if ("OPTIONS".equals(httpServletRequest.getMethod())) {
            httpServletResponse.setStatus(204);
        }

        filterChain.doFilter(servletRequest, servletResponse);
    }

    @Override
    public void destroy() {

    }
}

•    Shiro过滤器，配置允许OPTIONS请求

    

import lombok.extern.slf4j.Slf4j;
import org.apache.commons.lang3.StringUtils;
import org.apache.shiro.web.filter.authc.FormAuthenticationFilter;
import org.apache.shiro.web.util.WebUtils;

import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;

/**
 * @author pengyangyan
 */
@Slf4j
public class ShiroFiter extends FormAuthenticationFilter {

    @Override
    protected boolean isAccessAllowed(ServletRequest request, ServletResponse response, Object mappedValue) {
        boolean allowed = super.isAccessAllowed(request, response, mappedValue);
        if (!allowed) {
            // 判断请求是否是options请求
            String method = WebUtils.toHttp(request).getMethod();
            if (StringUtils.equalsIgnoreCase("OPTIONS", method)) {
                return true;
            }
        }
        return allowed;
    }

    @Override
    protected boolean onAccessDenied(ServletRequest request, ServletResponse response) throws Exception {
        return super.onAccessDenied(request, response);
    }
}

•    开启过滤器

   

import com.cqjtu.platform.filter.CorsFilter;
import com.cqjtu.platform.filter.ShiroFiter;
import lombok.extern.slf4j.Slf4j;
import org.springframework.boot.web.servlet.FilterRegistrationBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

/**
 * @author pengyangyan

@Slf4j
@Configuration
public class FilterConfig {

    @Bean
    public FilterRegistrationBean crosFilterRegistration(){

        FilterRegistrationBean registrationBean = new FilterRegistrationBean();
        //注入过滤器
        registrationBean.setFilter(new CorsFilter());
        //过滤器名称
        registrationBean.setName("CorsFilter");
        //拦截规则
        registrationBean.addUrlPatterns("/*");
        //过滤器顺序
        registrationBean.setOrder(FilterRegistrationBean.HIGHEST_PRECEDENCE);

        log.info("开启cros-Filter过滤器。");

        return registrationBean;
    }

    @Bean
    public FilterRegistrationBean shiroFilterRegistration(){

        FilterRegistrationBean registrationBean = new FilterRegistrationBean();
        //注入过滤器
        registrationBean.setFilter(new ShiroFiter());
        //过滤器名称

        log.info("开启shiro-Filter过滤器。");

        return registrationBean;
    }
}

2、Ajax的post请求出现options请求302，但是get请求正常。

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.cors.CorsConfiguration;
import org.springframework.web.cors.UrlBasedCorsConfigurationSource;
import org.springframework.web.filter.CorsFilter;

/**
 *  用于解决springboot ajax post跨域请求 options 302
 * @author pengyangyan
 */
@Configuration
public class CorsConfig {

    private CorsConfiguration buildConfig(){
        CorsConfiguration corsConfiguration = new CorsConfiguration();
        corsConfiguration.addAllowedOrigin("*");
        corsConfiguration.addAllowedHeader("*");
        corsConfiguration.addAllowedMethod("*");
        return corsConfiguration;
    }

    @Bean
    public CorsFilter corsFilter(){
        UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        source.registerCorsConfiguration("/**",buildConfig());
        return new CorsFilter(source);
    }
}
