SpringBoot+Shiro权限管理

完善之前的博客里的项目，本博客主要讲述Shiro的权限管理模块

 代码实例

        引入依赖

<dependency>  
    <groupId>org.apache.shiro</groupId>  
    <artifactId>shiro-spring-boot-starter</artifactId>  
    <version>1.7.0</version>  
</dependency>

        配置Shiro 

import org.apache.shiro.mgt.SecurityManager;  
import org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor;  
import org.apache.shiro.spring.web.ShiroFilterFactoryBean;  
import org.apache.shiro.spring.web.config.DefaultShiroFilterChainDefinition;  
import org.apache.shiro.spring.web.config.ShiroFilterChainDefinition;  
import org.apache.shiro.web.mgt.DefaultWebSecurityManager;  
import org.springframework.context.annotation.Bean;  
import org.springframework.context.annotation.Configuration;  
  
import javax.servlet.Filter;  
import java.util.HashMap;  
import java.util.Map;  
  
@Configuration  
public class ShiroConfig {  
  
    @Bean  
    public SecurityManager securityManager(MyRealm myRealm) {  
        DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();  
        securityManager.setRealm(myRealm);  
        return securityManager;  
    }  
  
    @Bean  
    public ShiroFilterFactoryBean shiroFilterFactoryBean(SecurityManager securityManager) {  
        ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();  
        shiroFilterFactoryBean.setSecurityManager(securityManager);  
        shiroFilterFactoryBean.setLoginUrl("/login");  
        shiroFilterFactoryBean.setUnauthorizedUrl("/403");  
  
        Map<String, Filter> filters = new HashMap<>();  
        // 可以添加自定义的过滤器  
        shiroFilterFactoryBean.setFilters(filters);  
  
        Map<String, String> filterChainDefinitionMap = new HashMap<>();  
        filterChainDefinitionMap.put("/login", "anon");  
        filterChainDefinitionMap.put("/**", "authc");  
  
        ShiroFilterChainDefinition chainDefinition = new DefaultShiroFilterChainDefinition();  
        chainDefinition.setChainDefinitionMap(filterChainDefinitionMap);  
        shiroFilterFactoryBean.setFilterChainDefinitionMap(chainDefinition.getChainDefinitionMap());  
  
        return shiroFilterFactoryBean;  
    }  
  
    @Bean  
    public AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor(SecurityManager securityManager) {  
        AuthorizationAttributeSourceAdvisor advisor = new AuthorizationAttributeSourceAdvisor();  
        advisor.setSecurityManager(securityManager);  
        return advisor;  
    }  
}

        自定义Realm 

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;  
  
public class MyRealm extends AuthorizingRealm {  
  
    @Autowired  
    private UserService userService; // 假设有一个UserService用于查询用户信息  
  
    @Override  
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {  
        String username = (String) principalCollection.getPrimaryPrincipal();  
        // 查询用户权限和角色  
        SimpleAuthorizationInfo authorizationInfo = new SimpleAuthorizationInfo();  
        // 假设从数据库中查询到的角色和权限  
        authorizationInfo.addRole("role1");  
        authorizationInfo.addStringPermission("user:delete");  
        return authorizationInfo;  
    }  
  
    @Override  
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {  
        UsernamePasswordToken token = (UsernamePasswordToken) authenticationToken;  
        String username = token.getUsername();  
  
        // 查询用户信息  
        User user = userService.findByUsername(username);  
        if (user == null) {  
            throw new UnknownAccountException("用户不存在");  
        }  
  
        // 返回验证信息  
        return new SimpleAuthenticationInfo(username, user.getPassword(), getName());  
    }  
}
