SpringBoot2.0与Shrio集成实战操作

 

1、创建springboot项目

 

2、添加相关依赖

thymeleaf、shrio等依赖

<dependency>
    <groupId>org.apache.shiro</groupId>
    <artifactId>shiro-spring</artifactId>
    <version>1.4.1</version>
</dependency>
<dependency>
    <groupId>org.apache.shiro</groupId>
    <artifactId>shiro-core</artifactId>
    <version>1.4.1</version>
</dependency>

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>

<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
</dependency>

3、添加Shrio配置类

ShiroConfig.java

package com.chlin.springbootshrio.config;

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.springframework.web.servlet.handler.SimpleMappingExceptionResolver;
import org.apache.shiro.mgt.SecurityManager;

import java.util.LinkedHashMap;
import java.util.Map;
import java.util.Properties;

/**

 * @ Date       ：Created in 10:18 2019/7/18
 */
@Configuration
public class ShiroConfig {

   @Bean
   public ShiroFilterFactoryBean shirFilter(SecurityManager securityManager) {
      System.out.println("ShiroConfiguration.shirFilter()");
      ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();
      shiroFilterFactoryBean.setSecurityManager(securityManager);
      //拦截器.
      Map<String,String> filterChainDefinitionMap = new LinkedHashMap<String,String>();
      // 配置不会被拦截的链接 顺序判断，因为前端模板采用了thymeleaf，这里不能直接使用 ("/static/**", "anon")来配置匿名访问，必须配置到每个静态目录
      filterChainDefinitionMap.put("/css/**", "anon");
      filterChainDefinitionMap.put("/fonts/**", "anon");
      filterChainDefinitionMap.put("/img/**", "anon");
      filterChainDefinitionMap.put("/js/**", "anon");
      filterChainDefinitionMap.put("/html/**", "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");
      //<!-- 过滤链定义，从上向下顺序执行，一般将/**放在最为下边 -->:这是一个坑呢，一不小心代码就不好使了;
      //<!-- authc:所有url都必须认证通过才可以访问; anon:所有url都都可以匿名访问-->
      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;
   }

   /**
    * 凭证匹配器
    * （由于我们的密码校验交给Shiro的SimpleAuthenticationInfo进行处理了
    * ）
    * @return
    */
   @Bean
   public HashedCredentialsMatcher hashedCredentialsMatcher(){
      HashedCredentialsMatcher hashedCredentialsMatcher = new HashedCredentialsMatcher();
      hashedCredentialsMatcher.setHashAlgorithmName("md5");//散列算法:这里使用MD5算法;
      hashedCredentialsMatcher.setHashIterations(2);//散列的次数，比如散列两次，相当于 md5(md5(""));
      return hashedCredentialsMatcher;
   }

   @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;
   }

   /**
    *  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(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");//数据库异常处理
      mappings.setProperty("UnauthorizedException","/user/403");
      r.setExceptionMappings(mappings);  // None by default
      r.setDefaultErrorView("error");    // No default
      r.setExceptionAttribute("exception");     // Default is "exception"
      //r.setWarnLogCategory("example.MvcLogger");     // No default
      return r;
   }

}

MyShiroRealm.java

package com.chlin.springbootshrio.config;

import com.chlin.springbootshrio.entity.SysPermission;
import com.chlin.springbootshrio.entity.SysRole;
import com.chlin.springbootshrio.entity.User;
import com.chlin.springbootshrio.service.IUserService;
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.subject.PrincipalCollection;
import org.apache.shiro.util.ByteSource;

import javax.annotation.Resource;

/**
 * @ desc：
 * @ Author     ：chenhl01.
 * @ Date       ：Created in 10:12 2019/7/18
 */
public class MyShiroRealm extends AuthorizingRealm {
   @Resource
   private IUserService userService;

   //权限信息，包括角色以及权限
   @Override
   protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
      System.out.println("权限配置-->MyShiroRealm.doGetAuthorizationInfo()");
      SimpleAuthorizationInfo authorizationInfo = new SimpleAuthorizationInfo();
      //如果身份认证的时候没有传入User对象，这里只能取到userName
      //也就是SimpleAuthenticationInfo构造的时候第一个参数传递需要User对象
      User user = (User) principals.getPrimaryPrincipal();

      for (SysRole role : user.getRoleList()) {
         authorizationInfo.addRole(role.getRole());
         for (SysPermission p : role.getPermissions()) {
            authorizationInfo.addStringPermission(p.getPermission());
         }
      }
      return authorizationInfo;
   }

   /*主要是用来进行身份认证的，也就是说验证用户输入的账号和密码是否正确。*/
   @Override
   protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token)
         throws AuthenticationException {
      System.out.println("MyShiroRealm.doGetAuthenticationInfo()");
      //获取用户的输入的账号.
      String userName = (String) token.getPrincipal();
      System.out.println(token.getCredentials());
      //通过username从数据库中查找 User对象.
      //实际项目中，这里可以根据实际情况做缓存，如果不做，Shiro自己也是有时间间隔机制，2分钟内不会重复执行该方法
      User user = userService.findByUserName(userName);
      System.out.println("----->>user=" + user);
      if (user == null) {
         return null;
      }
      SimpleAuthenticationInfo authenticationInfo = new SimpleAuthenticationInfo(
            user, //这里传入的是user对象，比对的是用户名，直接传入用户名也没错，但是在授权部分就需要自己重新从数据库里取权限
            user.getPassword(), //密码
            ByteSource.Util.bytes(user.getCredentialsSalt()),//salt=username+salt
            getName()  //realm name
      );
      return authenticationInfo;
   }

}

4、登录逻辑部分代码

UsernamePasswordToken token = new UsernamePasswordToken(userName, password);

// 4、认证
try {
   currentUser.login(token);// 传到MyAuthorizingRealm类中的方法进行认证
Session session = currentUser.getSession();
   session.setAttribute("userName", userName);
   loginResult.setLogin(true);
   return loginResult;
} catch (UnknownAccountException e) {
   e.printStackTrace();
   msg = "UnknownAccountException -- > 账号不存在：";
} catch (IncorrectCredentialsException e) {
   msg = "IncorrectCredentialsException -- > 密码不正确：";
} catch (AuthenticationException e) {
   e.printStackTrace();
   msg = "用户验证失败";
}

currentUser.login()方法执行MyShiroRealm中的doGetAuthenticationInfo来进行用户认证
