## 一. springboot 整合 shiro ##

### 1. 引入依赖 ###

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

### 2.两个配置文件 ShiroConfig 和 MyShiroRealm ###

#### ShiroConfig ####

@Configuration
    public class ShiroConfig {
        
    
        @Bean
        @ConditionalOnMissingBean
        public DefaultAdvisorAutoProxyCreator defaultAdvisorAutoProxyCreator() {
        
            DefaultAdvisorAutoProxyCreator defaultAAP = new DefaultAdvisorAutoProxyCreator();
            defaultAAP.setProxyTargetClass(true);
            return defaultAAP;
        }
        /**
         * 密码校验规则HashedCredentialsMatcher
         * 这个类是为了对密码进行编码的 ,
         * 防止密码在数据库里明码保存 , 当然在登陆认证的时候 ,
         * 这个类也负责对form里输入的密码进行编码
         * 处理认证匹配处理器：如果自定义需要实现继承HashedCredentialsMatcher
         */
        @Bean
        public HashedCredentialsMatcher hashedCredentialsMatcher() {
        
            //Shiro自带加密
            HashedCredentialsMatcher credentialsMatcher = new HashedCredentialsMatcher();
            //散列算法使用md5
            credentialsMatcher.setHashAlgorithmName("md5");
            //散列次数，1表示md5加密1次
            credentialsMatcher.setHashIterations(1);
            credentialsMatcher.setStoredCredentialsHexEncoded(true);
            return credentialsMatcher;
        }
    
        //将自己的验证方式加入容器
        @Bean
        public MyShiroRealm myShiroRealm() {
        
            MyShiroRealm myShiroRealm = new MyShiroRealm();
            myShiroRealm.setCredentialsMatcher(hashedCredentialsMatcher());
            return myShiroRealm;
        }
    
        //权限管理，配置主要是Realm的管理认证
        @Bean
        public SecurityManager securityManager() {
        
            DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
            securityManager.setRealm(myShiroRealm());
            return securityManager;
        }
    
        @Bean
        public ShiroFilterFactoryBean shiroFilterFactoryBean(SecurityManager securityManager) {
        
            ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();
            shiroFilterFactoryBean.setSecurityManager(securityManager);
            Map<String, String> filterMap = new HashMap<String, String>();
            // 登出
            filterMap.put("/logout", "logout");
            // swagger
            filterMap.put("/swagger-ui.html", "anon");
            filterMap.put("/swagger-resources/**", "anon");
            filterMap.put("/v2/**", "anon");
            filterMap.put("/webjars/**", "anon");
            filterMap.put("/static/**", "anon");
            filterMap.put("/reload","anon");
            filterMap.put("/csrf","anon");
            // 对生成的es查询接口放行
            filterMap.put("/ES/**","anon");
            // 对所有用户认证
            filterMap.put("/**", "authc");
    //        filterMap.put("/**", "user");
            // 登录
            shiroFilterFactoryBean.setLoginUrl("/login");
    
            // 错误页面，认证不通过跳转
            shiroFilterFactoryBean.setUnauthorizedUrl("/error");
            shiroFilterFactoryBean.setFilterChainDefinitionMap(filterMap);
            return shiroFilterFactoryBean;
        }
    
        /**
         * spring与shiro的整合
         */
        @Bean
        public AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor(SecurityManager securityManager) {
        
            AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor = new AuthorizationAttributeSourceAdvisor();
            authorizationAttributeSourceAdvisor.setSecurityManager(securityManager);
            return authorizationAttributeSourceAdvisor;
        }
    
    }

#### MyShiroRealm ####

public class MyShiroRealm extends AuthorizingRealm {
        
    
        @Autowired
        private LoginMapper loginMapper;
    
    
        /**
         * 认证登录
         * @param token
         * @return
         * @throws AuthenticationException
         */
        @Override
        protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
        
            //token携带了用户信息
            UsernamePasswordToken usernamePasswordToken = (UsernamePasswordToken) token;
            //获取前端输入的用户名
            String userName  = usernamePasswordToken.getUsername();
            //根据用户名查询数据库中对应的记录
            User user = loginMapper.findByName(userName);
            //当前realm对象的name
            String realmName = getName();
            //盐值
            ByteSource credentialsSalt = ByteSource.Util.bytes(user.getUsername()+user.getSalt());
            //封装用户信息，构建AuthenticationInfo对象并返回
            AuthenticationInfo authcInfo = new SimpleAuthenticationInfo(userName, user.getPassword(),
                    credentialsSalt, realmName);
            return authcInfo;
        }
    
        // 角色权限,因为我没有使用 shiro 提供的授权方法，所以没有实现这个方法
        @Override
        protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
        
            return null;
        }
    
    }

## 二.添加新用户 ##

public void addUser(User user) {
        
            // 生成一个随机4位数
            String salt = RandomUtil.randomNumbers(4);
            user.setSalt(salt);
            // 两个参数，第一个是需要加密的字符串，第二个是盐
            Md5Hash hash = new Md5Hash(user.getPassword(), user.getUsername()+salt);
            user.setPassword(hash.toString());
            mapper.addUser(user);
        }
