## 1.我们简单搭建ssm框架 ##

可以参考[http://t.csdn.cn/OI3Jr][http_t.csdn.cn_OI3Jr]

### 2.ssm整合shiro(前后端不分离) ###

基本效果如下

### 2.1---认证功能 ###

所需数据库资源如下：

(1)引入依赖

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

(2)修改spring配置文件

<bean id="securityManager" class="org.apache.shiro.web.mgt.DefaultWebSecurityManager">
               <property name="realm" ref="myRealm"/>
        </bean>
        <bean id="myRealm" class="com.ykq.realm.MyRealm">
             <property name="credentialsMatcher" ref="credentialsMatcher"/>
        </bean>
        
        <bean id="credentialsMatcher" class="org.apache.shiro.authc.credential.HashedCredentialsMatcher">
             <property name="hashAlgorithmName" value="MD5"/>
             <property name="hashIterations" value="1024"/>
        </bean>
    
        
        <bean id="shiroFilter" class="org.apache.shiro.spring.web.ShiroFilterFactoryBean">
             <property name="securityManager" ref="securityManager"/>
             
             <property name="loginUrl" value="/login.jsp"/>
             
             <property name="filterChainDefinitions">
                  <value>
                       /login=anon
                       /**=authc
                  </value>
             </property>
        </bean>

(3)修改web.xml文件

<filter>
            <filter-name>shiroFilter</filter-name>
            <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
        </filter>
        <filter-mapping>
            <filter-name>shiroFilter</filter-name>
            <url-pattern>/*</url-pattern>
        </filter-mapping>

(4)修改login.jsp

(5)controller

package com.cgm.controller;
    
    import com.cgm.vo.LoginVo;
    import com.cgm.vo.Result;
    import lombok.extern.slf4j.Slf4j;
    import org.apache.shiro.SecurityUtils;

    /**

     */
    @Controller
    //@Slf4j
    public class loginController {
        @PostMapping("/login")
        @ResponseBody
        public String login(LoginVo loginVo) {
           if (loginVo==null){
               return new Result(500,"请登录",null);
           }
            Subject subject = SecurityUtils.getSubject();
            UsernamePasswordToken token = new UsernamePasswordToken(loginVo.getUsername(), loginVo.getPassword());
             try {
                subject.login(token);
                return "success"; //经过视图解析器 /WEB-INF/views/success.jsp
            }catch (Exception e){
                e.printStackTrace();
                return "redirect:/login.jsp";
            }
        }
       
    }

(6)MyRealm修改

public class MyRealm extends AuthorizingRealm {
        @Autowired
        private UserService userService;
        protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
            return null;
        }
    
        protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
            //1.获取登录账号
            String username = token.getPrincipal().toString();
            //2.根据账号获取用户信息
            User user= userService.selectByUsername(username);
            if(user!=null){
                ByteSource salt=ByteSource.Util.bytes(user.getSalt());
                SimpleAuthenticationInfo info=new SimpleAuthenticationInfo(user,user.getUserpwd(),salt,this.getName());
                return info;
            }
    
            return null;
        }
    }

(7) UserService的代码

@Service
    public class UserServiceImpl implements UserService {
        @Autowired
        private UserDao userDao;
        public User selectByUsername(String username) {
            User user = userDao.findByUsername(username);
            return user;
        }
    }

(8)dao方法和映射代码

public interface UserDao {
        User findByUsername(String username);
    }

<?xml version="1.0" encoding="UTF-8" ?>
    <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
            "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
    
    <mapper namespace="com.cgm.dao.UserDao">
    
        <select id="findByUsername" resultType="com.cgm.entity.User">
                select * from user where username=#{username}
        </select>
    </mapper>

(9)测试

![fde1f715394e44e78f927027a59ea9ef.png][]

### 2.1---授权 ###

（1）修改myRealm

//授权
        protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
            //获取当前登录者的账号
            User user = (User) principals.getPrimaryPrincipal();
            //调用userSerice中的方法--根据id
           List<String> permissions= userService.selectPermissionByUserid(user.getUserid());
           if(permissions.size()!=0){
               SimpleAuthorizationInfo info=new SimpleAuthorizationInfo();
               info.addStringPermissions(permissions);
               return info;
           }
            return null;
        }

(2)PermissionService

@Service
    public class PermissionServiceImpl implements PermissionService {
        @Autowired
        private PermissionDao permissionDao;
        public List<String> selectPermissionByUserid(Integer userid) {
            List<Permission> permissionList= permissionDao.findPermissionByUserid(userid);
            List<String> collect = permissionList.stream().map(item -> item.getPercode()).collect(Collectors.toList());
            return collect;
        }
    }

(3)PermissionDao和映射

List<Permission> findPermissionByUserid(Integer userid);
    }

<select id="findPermissionByUserid" resultType="com.ykq.entity.Permission">
            select p.* from user_role ur join role_permission rp on ur.roleId=rp.roleid
            join permission p on rp.perid=p.perid where ur.userid=#{userId}
        </select>

（4）测试

任何人登录都看到了所有的按钮权限---想不同人登录具有什么权限能够看懂神门按钮。

解决方案:在jsp中使用shiro标签库

    </html>

我们虽然在浏览器看到相应的按钮---可是我可以同别的方式能访问后台对应的资源。 shiro提供了注解。---判断该是否具有该注解的权限---才会执行对应的资源方法

package com.cgm.controller;
    
    import org.apache.shiro.authz.annotation.RequiresPermissions;
    import org.springframework.web.bind.annotation.GetMapping;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RestController;
    
    /**
     * @Title: UserController
     * @Package com.cgm.controller
     * @Author 常小明
     * @Date 2023/7/6 17:45
     * @program
     */
    @RestController
    @RequestMapping("/user")
    public class UserController {
    
        @GetMapping("/query")
        @RequiresPermissions(value = "user:query")
        public String query(){
            return "user:query------------------------";
        }
    
        @GetMapping("/update")
        @RequiresPermissions(value = "user:update")
        public String update(){
            return "user:update------------------------";
        }
    
        @GetMapping("/delete")
        @RequiresPermissions(value = "user:delete")
        public String delete(){
            return "user:delete------------------------";
        }
    
        @GetMapping("/insert")
        @RequiresPermissions(value = "user:insert")
        public String insert(){
            return "user:insert------------------------";
        }
    
        @GetMapping("/export")
        @RequiresPermissions(value = "user:export")
        public String export(){
            return "user:export------------------------";
        }
    }

发现上面注解不生效-----spring没有开启该注解的驱动---spring配置文件加入如下内容

<bean id="lifecycleBeanPostProcessor"
              class="org.apache.shiro.spring.LifecycleBeanPostProcessor" />
        <bean
                class="org.springframework.aop.framework.autoproxy.DefaultAdvisorAutoProxyCreator"
                depends-on="lifecycleBeanPostProcessor" />
        <bean
                class="org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor">
            <property name="securityManager" ref="securityManager" />
        </bean>

后续会对前后端进行简单分离，请参考其他作品
