shiro学习

最近在学习shiro，今天做一个总结
shiro简单介绍
Shiro是Apache下的一个开源项目，我们称之为Apache Shiro。它是一个很易用与Java项目的的安全框架，提供了认证、授权、加密、会话管理，与 Spring Security 一样都是做一个权限的安全框架，但是与Spring Security 相比，在于 Shiro 使用了比较简单易懂易于使用的授权方式。
Apache Shiro的三大核心组件
Subject 当前用户的操作
SecurityManager 用于管理所有的Subject
Realms 用于进行权限信息的验证，也是我们需要自己实现的
首先我们先进行maven依赖的添加

        <dependency>//添加log日志

yml中的配置

spring:
  datasource:
    url: jdbc:mysql://localhost:3306/db_shiro?useUnicode=true&characterEncoding=UTF-8&useSSL=false&serverTimezone=UTC
    username: root
    password: "000000"
  thymeleaf:
    mode: LEGACYHTML5
mybatis:
  type-aliases-package: com.example.shiro.domain
  mapper-locations: classpath:mapper/*Mapper.xml
  configuration:
    map-underscore-to-camel-case: true
    use-generated-keys: true

thymeleaf的配置

spring.thymeleaf.mode=HTML5
spring.thymeleaf.encoding=UTF-8
spring.thymeleaf.content-type=text/html
开发时关闭缓存,不然没法看到实时页面
spring.thymeleaf.cache=false

启动类上添加扫描的mapper

@SpringBootApplication
@MapperScan("com.example.shiro.mapper")
public class ShiroApplication {
    public static void main(String[] args) {
        SpringApplication.run(ShiroApplication.class, args);
    }
}

shiro文件的配置

@Configuration
public class ShiroConfig {
   @Bean
   public ShiroFilterFactoryBean shirFilter(SecurityManager securityManager){
      ShiroFilterFactoryBean shiroFilterFactoryBean=new ShiroFilterFactoryBean();

      shiroFilterFactoryBean.setSecurityManager(securityManager);

      shiroFilterFactoryBean.setLoginUrl("/login.html");//登录时跳转的页面

      shiroFilterFactoryBean.setSuccessUrl("/success");//认证成功后跳转的页面

      shiroFilterFactoryBean.setUnauthorizedUrl("/403.jsp");//未授权后跳转的页面

      Map  filterChainDefinitionMap=new LinkedHashMap();

      filterChainDefinitionMap.put("/login1","anon");//anon,无需认证

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

      filterChainDefinitionMap.put("/","authc");//authc,需要认证

      shiroFilterFactoryBean.setFilterChainDefinitionMap(filterChainDefinitionMap);

      System.out.println("Shiro拦截器配置成功");

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


   @Bean
   public MyRealm myShiroRealm(){
      return new MyRealm();
   }

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

Controller中进行用户密码的认证

@Controller
public class UserController {
    private String encoding = "UTF-8";
    @PostMapping("/login1")
    public String login(HttpServletRequest request) throws UnsupportedEncodingException {
        request.setCharacterEncoding(encoding);
        String username = request.getParameter("username");
        String password = request.getParameter("password");
        UsernamePasswordToken token = new UsernamePasswordToken(username, password);
        token.setRememberMe(true);
        Subject currentUser = SecurityUtils.getSubject();
        try {
            currentUser.login(token);
            return "success";
        } catch (Exception e) {
            request.setAttribute("user", username);
            request.setAttribute("errorMsg", "用户名或密码错误");
            return "login";
        }
    }
}

自定义realm

public class MyRealm extends AuthorizingRealm{
    @Autowired
    private UserServiceImpl userService;
    /***
     *
     *为当前登录的角色授予角色和权限
     */
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) { 
        String username= (String) principalCollection.getPrimaryPrincipal();
        SimpleAuthorizationInfo authenticationInfo= new SimpleAuthorizationInfo();
        authenticationInfo.setStringPermissions(userService.getPermissionByUserName(username));
        authenticationInfo.setRoles(userService.getRolesByUserName(username));
        return null;
    }
    /**
     * 验证当前登录的用户
     */
    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws  AuthenticationException {
        String username= (String) authenticationToken.getPrincipal();
        User user=userService.getUserByUsername(username);
        if (user!=null){
            return new SimpleAuthenticationInfo(user.getUserName(),user.getPassword(),"xx");
        }else{
            return null;
        }
    }
}
