springboot中使用shiro

我会带着你远行 2022-05-28 11:49 135阅读 0赞

首先在pom文件中添加shiro的jar包

<dependency>
           <groupId>org.apache.shiro</groupId>
           <artifactId>shiro-spring</artifactId>
           <version>1.2.4</version>
       </dependency>

在项目中添加shiro的配置类ShiroConfiguration

@Configuration
    public class ShiroConfiguration { 
    
    
    
        @Bean
        public MyShiroRealm myShiroRealm(){
            MyShiroRealm myShiroRealm=new MyShiroRealm();
            myShiroRealm.setCachingEnabled(false);
            return myShiroRealm;
        }
        @Bean
        public DefaultWebSecurityManager defaultWebSecurityManager(MyShiroRealm myShiroRealm){
            DefaultWebSecurityManager securityManager=new DefaultWebSecurityManager();
            securityManager.setRealm(myShiroRealm);
            return securityManager;
        }
    
        @Bean
        public ShiroFilterFactoryBean shiroFilter(DefaultWebSecurityManager defaultWebSecurityManager){
            ShiroFilterFactoryBean shiroFilterFactoryBean=new ShiroFilterFactoryBean();
            shiroFilterFactoryBean.setLoginUrl("/login");
            shiroFilterFactoryBean.setSuccessUrl("/subLogin");
            shiroFilterFactoryBean.setSecurityManager(defaultWebSecurityManager);
            //shiroFilterFactoryBean.setUnauthorizedUrl("/login");
            Map<String,String> filerChainDefinitionMap=new LinkedHashMap<>();
            filerChainDefinitionMap.put("/logout","logout");
            filerChainDefinitionMap.put("/static/**","anon");
            filerChainDefinitionMap.put("/loginPage","anon");
            filerChainDefinitionMap.put("/login","anon");
            filerChainDefinitionMap.put("/success","anon");
            filerChainDefinitionMap.put("/**","authc");
            shiroFilterFactoryBean.setFilterChainDefinitionMap(filerChainDefinitionMap);
            return shiroFilterFactoryBean;
        }
    
    
    
    }

因为上面需要ShiroRealm我们这里自己创建一个MyShiroRealm ，这里面写的是验证登陆人的账号密码是否正确，和验证账号的权限信息。

public class MyShiroRealm extends AuthorizingRealm { 
    
        @Resource
        private TbUserDao userDao;
    
        @Override
        protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
          ShiroUser shiroUser = (ShiroUser) principals.getPrimaryPrincipal();
    
            SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();
            //权限表中权限拼接的set集合
            Set<String> permNames = userService.findPermNamesByUserId(shiroUser.getId());
    
            info.addStringPermissions(permNames);
    
            logger.info(String.format("用户[%s]登录成功,获取权限集合:%s", shiroUser.getLoginName(), permNames.toString()));
    
            return info;
        }
    
        @Override
        protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
            UsernamePasswordToken token=(UsernamePasswordToken)authenticationToken;
            String userName = token.getUsername();//查看是否有此用户
            TbUser user=userDao.findTbUserByLoginName(userName);
            if(user==null) return null;
            ShiroUser shiroUser = new ShiroUser();
            try{
                shiroUser.setId(user.getId());
                shiroUser.setLoginName(user.getLoginName());
                shiroUser.setName(user.getName());
                shiroUser.setDataRange(user.getDataRange());
                if(user.getCompany() != null){
                    shiroUser.setCompanyId(user.getCompany().getId());
                    shiroUser.setCompanyName(user.getCompany().getCompanyName());
                    shiroUser.setState(user.getCompany().getState());
                }else{
                    shiroUser.setState("1");
                }
                String roleNames = "";
                for(TBRole r : user.getRoles()){
                    roleNames += ","+r.getName();
                }
                shiroUser.setRoleNames(roleNames.substring(1));
            }catch(Exception e){
                e.printStackTrace();
            }
                return new SimpleAuthenticationInfo(shiroUser,user.getPassWord(),user.getLoginName());
    
        }
