SpringBoot与Shiro的整合

ゝ一世哀愁。 2021-12-04 00:15 315阅读 0赞

> Shiro是一个安全框架。  
> Subject： 代表当前正在执行操作的用户，但Subject代表的可以是人，也可以是任何第三方系统帐号。当然每个subject实例都会被绑定到SercurityManger上。  
> SecurityManger:SecurityManager是Shiro核心，主要协调Shiro内部的各种安全组件。  
> Realm: 用户数据和Shiro数据交互的桥梁。比如需要用户身份认证、权限认证。都是需要通过Realm来读取数据。

1.  添加Maven依赖

<dependency>
               <groupId>org.apache.shiro</groupId>
               <artifactId>shiro-web</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.apache.shiro</groupId>
               <artifactId>shiro-spring</artifactId>

           <dependency>

               <artifactId>shiro-ehcache</artifactId>
               <version>1.4.1</version>
           </dependency>
    
           <dependency>
               <groupId>org.crazycake</groupId>
               <artifactId>shiro-redis</artifactId>
               <version>3.2.3</version>
           </dependency>

1.  添加自定义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 java.util.HashSet;
    import java.util.Set;
    
    public class CustomRealm extends AuthorizingRealm {
    
        @Override
        protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
            SimpleAuthorizationInfo simpleAuthorizationInfo = new SimpleAuthorizationInfo();
            Set<String> permissionList = new HashSet<>();
            permissionList.add("WORKER");
            simpleAuthorizationInfo.addStringPermissions(permissionList);
            return simpleAuthorizationInfo;
        }
    
        @Override
        protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
            UsernamePasswordToken token = (UsernamePasswordToken) authenticationToken;
            String username = token.getUsername();
            String password = new String(token.getPassword());
            if ("root".equals(username) && "123456".equals(password)) {
                return new SimpleAuthenticationInfo(new Object(), token.getPassword(), token.getUsername());
            }
            throw new RuntimeException("账号或密码不正确，请重新登陆");
        }
    }

1.  添加shiro的配置文件

import com.example.demo.shiro.CustomRealm;
    import org.apache.shiro.mgt.DefaultSecurityManager;
    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.DefaultWebSecurityManager;
    import org.springframework.aop.framework.autoproxy.DefaultAdvisorAutoProxyCreator;
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;
    import org.springframework.context.annotation.DependsOn;
    
    import java.util.LinkedHashMap;
    import java.util.Map;
    
    @Configuration
    public class ShiroConfig {
    
        @Bean
        public ShiroFilterFactoryBean shiroFilterFactoryBean(SecurityManager securityManager) {
            ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();
            shiroFilterFactoryBean.setSecurityManager(securityManager);
            shiroFilterFactoryBean.setLoginUrl("/login");
            Map<String, String> filterChainDefinitionMap = new LinkedHashMap<>();
            filterChainDefinitionMap.put("/login", "anon"); // 登陆
            filterChainDefinitionMap.put("/**", "authc");// 需要认证才可以访问
            shiroFilterFactoryBean.setFilterChainDefinitionMap(filterChainDefinitionMap);
            return shiroFilterFactoryBean;
        }
    
        @Bean
        public SecurityManager securityManager() {
            DefaultSecurityManager securityManager = new DefaultWebSecurityManager();
            securityManager.setRealm(customRealm());
            return securityManager;
        }
    
        @Bean
        public CustomRealm customRealm() {
            return new CustomRealm();
        }
    
        @Bean
        public LifecycleBeanPostProcessor lifecycleBeanPostProcessor() {
            return new LifecycleBeanPostProcessor();
        }
    
        /**
         * 开启Shiro的注解(如@RequiresRoles,@RequiresPermissions),需借助SpringAOP扫描使用Shiro注解的类,并在必要时进行安全逻辑验证
         */
        @Bean
        @DependsOn({"lifecycleBeanPostProcessor"})
        public DefaultAdvisorAutoProxyCreator advisorAutoProxyCreator() {
            DefaultAdvisorAutoProxyCreator advisorAutoProxyCreator = new DefaultAdvisorAutoProxyCreator();
            advisorAutoProxyCreator.setProxyTargetClass(true);
            return advisorAutoProxyCreator;
        }
    
        @Bean
        public AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor() {
            AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor = new AuthorizationAttributeSourceAdvisor();
            authorizationAttributeSourceAdvisor.setSecurityManager(securityManager());
            return authorizationAttributeSourceAdvisor;
        }
    }

1.  在Controller中使用shiro

import org.apache.shiro.SecurityUtils;
    import org.apache.shiro.authc.UsernamePasswordToken;
    import org.apache.shiro.authz.annotation.RequiresPermissions;
    import org.apache.shiro.subject.Subject;
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RequestParam;
    import org.springframework.web.bind.annotation.ResponseBody;
    
    @Controller
    public class UserController {
    
        @RequestMapping("login")
        @ResponseBody
        public String login(@RequestParam("username") String username, @RequestParam("password") String password) {
            Subject subject = SecurityUtils.getSubject();
            UsernamePasswordToken authenticationToken = new UsernamePasswordToken(username, password);
            try {
                subject.login(authenticationToken);
            } catch (Exception exp) {
                return "账号或密码不正确, 请重新登录";
            }
    
            if (subject.isAuthenticated()) {
                return "登陆成功";
            } else {
                authenticationToken.clear();
                return "登陆失败";
            }
        }
    
        @RequestMapping("index")
        public String toIndex() {
            return "index";
        }
    
        @RequestMapping("admin")
        @RequiresPermissions("WORKER")
        public String toAdmin() {
            return "admin";
        }
    }
