springboot加shiro用户认证集成

1、简介

shiro是由apache基金会旗下的强大的安全校验框架，执行身份验证、授权、密码和会话管理。使用Shiro的易于理解的API,从最小的移动应用程序到最大的网络和企业应用程序。本博客展示一个用户认证的demo，看看用shiro怎么来做用户认证的。

2、maven依赖

这里的sprigboot的版本是2.1.6.RELEASE

    
      org.springframework.boot
      spring-boot-starter-web
    
    
      com.alibaba
      fastjson
      1.2.36
    
    
      org.apache.shiro
      shiro-spring
      1.4.0
    
    
      org.apache.tomcat.embed
      tomcat-embed-jasper
    

3、sql

用户信息表

CREATE TABLE `userinfo` (
  `id` int(11) NOT NULL,
  `user_id` int(11) NOT NULL,
  `user_name` varchar(64) DEFAULT NULL,
  `name` varchar(64) DEFAULT NULL,
  `password` varchar(64) DEFAULT NULL,
  `salt` varchar(32) DEFAULT NULL,
  `status` smallint(2) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

4、springboot 配置shiro

shiroConfig.java

package com.example.demo2.config;

import java.util.LinkedHashMap;
import java.util.Map;
import java.util.Properties;
import org.apache.shiro.authc.credential.HashedCredentialsMatcher;
import org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor;
import org.apache.shiro.spring.web.ShiroFilterFactoryBean;
import org.apache.shiro.web.mgt.DefaultWebSecurityManager;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.apache.shiro.mgt.SecurityManager;
import org.springframework.web.servlet.handler.SimpleMappingExceptionResolver;

@Configuration
public class ShiroConfig {

    @Bean
    public ShiroFilterFactoryBean shiroFilter(SecurityManager securityManager){
        System.out.println("ShiroConfiguration.shirFilter()");
        ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();
        shiroFilterFactoryBean.setSecurityManager(securityManager);
        //拦截器.
        Map filterChainDefinitionMap = new LinkedHashMap();
        // 配置不会被拦截的链接 顺序判断
        filterChainDefinitionMap.put("/static/**", "anon");
        //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("/logout", "logout");
        //:这是一个坑呢，一不小心代码就不好使了;
        //
        filterChainDefinitionMap.put("/**", "authc");
        // 如果不设置默认会自动寻找Web工程根目录下的"/login.jsp"页面
        shiroFilterFactoryBean.setLoginUrl("/login");
        // 登录成功后要跳转的链接
        shiroFilterFactoryBean.setSuccessUrl("/index");

        //未授权界面;
        shiroFilterFactoryBean.setUnauthorizedUrl("/403");
        shiroFilterFactoryBean.setFilterChainDefinitionMap(filterChainDefinitionMap);
        return shiroFilterFactoryBean;
    }

    @Bean
    public MyShiroRealm myShiroRealm(){
        MyShiroRealm myShiroRealm = new MyShiroRealm();
        myShiroRealm.setCredentialsMatcher(hashedCredentialsMatcher());
        return myShiroRealm;
    }

    @Bean
    public SecurityManager securityManager(){
        DefaultWebSecurityManager securityManager =  new DefaultWebSecurityManager();
        securityManager.setRealm(myShiroRealm());
        return securityManager;
    }

    @Bean
    public HashedCredentialsMatcher hashedCredentialsMatcher(){
        HashedCredentialsMatcher hashedCredentialsMatcher = new HashedCredentialsMatcher();
        //散列算法:这里使用MD5算法;
        hashedCredentialsMatcher.setHashAlgorithmName("md5");
        //散列的次数，比如散列两次，相当于 md5(md5(""));
        hashedCredentialsMatcher.setHashIterations(2);
        return hashedCredentialsMatcher;
    }

    @Bean
    public AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor(SecurityManager securityManager){
        AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor = new AuthorizationAttributeSourceAdvisor();
        authorizationAttributeSourceAdvisor.setSecurityManager(securityManager);
        return authorizationAttributeSourceAdvisor;
    }

    @Bean(name="simpleMappingExceptionResolver")
    public SimpleMappingExceptionResolver
    createSimpleMappingExceptionResolver() {
        SimpleMappingExceptionResolver r = new SimpleMappingExceptionResolver();
        Properties mappings = new Properties();
        mappings.setProperty("DatabaseException", "databaseError");
        mappings.setProperty("UnauthorizedException","403");
        r.setExceptionMappings(mappings);
        r.setDefaultErrorView("error");
        r.setExceptionAttribute("ex");
        return r;
    }
}

MyshiroRealm.java

package com.example.demo2.config;

import com.stock.stockapi.dto.UserInfoDTO;
import com.stock.stockapi.dto.UserRoleDTO;
import java.util.List;
import lombok.extern.slf4j.Slf4j;
import org.apache.shiro.authc.AuthenticationException;
import org.apache.shiro.authc.AuthenticationInfo;
import org.apache.shiro.authc.AuthenticationToken;
import org.apache.shiro.authc.SimpleAuthenticationInfo;
import org.apache.shiro.authz.AuthorizationInfo;
import org.apache.shiro.authz.SimpleAuthorizationInfo;
import org.apache.shiro.realm.AuthorizingRealm;
import org.apache.shiro.realm.SimpleAccountRealm;
import org.apache.shiro.subject.PrincipalCollection;
import org.apache.shiro.util.ByteSource;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.HttpEntity;
import org.springframework.http.ResponseEntity;
import org.springframework.web.client.RestTemplate;

 **/
@Slf4j
public class MyShiroRealm extends AuthorizingRealm {

    @Autowired
    RestTemplate restTemplate;

    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
        SimpleAuthorizationInfo simpleAuthorizationInfo = new SimpleAuthorizationInfo();
        UserInfoDTO userInfoDTO = (UserInfoDTO)principalCollection.getPrimaryPrincipal();
        HttpEntity entity = new HttpEntity<>(userInfoDTO);
        ResponseEntity responseEntity = restTemplate.
            getForEntity("http://localhost:8080/stock/save", Boolean.class, "");
        return null;
    }

    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
        String userName = (String) token.getPrincipal();
        log.info("当前用户token {}", token.getCredentials());
        QueryUserInfoReqDTO reqDTO = new QueryUserInfoReqDTO();
        reqDTO.setUserName(userName);
        UserInfoDTO userInfoDTO = restTemplate.postForObject("http://localhost:8080/user/queryUserByName", reqDTO, UserInfoDTO.class);
        if (userInfoDTO != null) {
            SimpleAuthenticationInfo authorizationInfo =
                    new SimpleAuthenticationInfo(userInfoDTO, userInfoDTO.getPassword(), getName());
            return authorizationInfo;
        }
        return null;
    }
}

我这里直接用来restful来提供远程服务，大家也可以在项目中使用其他的远程过程调用，（例如dubbo，不过需要搭建注册中心，本人闲麻烦）
下面来介绍一些几个主要bean的作用。
ShiroFilterFactoryBean 的作用主要是用来拦截需要验证的url。可以看到上面配置了登录拦截，以及权限验证拦截，和验证通过之后跳转的页面。
MyShiroRealm
这个是自定义的Realm，继承了shiro的AuthorizingRealm，其中有两个重要的方法，一个是doGetAuthorizationInfo（权限校验），一个是doGetAuthenticationInfo（认证校验），在ShiroFilterFactoryBean 中配置的拦截url，都会经过这两个方法的校验。也是shiro的核心方法。

结语：
以上就是本人最近学习shiro的例子，希望能给大家带来帮助。
