3.2、配置文件

dataSource=org.springframework.jdbc.datasource.DriverManagerDataSource
#数据库url
spring.datasource.url=jdbc:mysql://127.0.0.1:3306/user?useUnicode=true&characterEncoding=UTF-8&allowMultiQueries=true
#数据库账号

3.3、数据库设计
数据库跟上一篇一样，看过的跳过
shiro_user表：

DROP TABLE IF EXISTS `shiro_user`;
CREATE TABLE `shiro_user`  (
  `ID` int(11) NOT NULL AUTO_INCREMENT,
  `USER_NAME` varchar(255) CHARACTER SET latin1 COLLATE latin1_swedish_ci NULL DEFAULT NULL,
  `PASSWORD` varchar(255) CHARACTER SET latin1 COLLATE latin1_swedish_ci NULL DEFAULT NULL,
  PRIMARY KEY (`ID`) USING BTREE
) ENGINE = InnoDB AUTO_INCREMENT = 2 CHARACTER SET = latin1 COLLATE = latin1_swedish_ci ROW_FORMAT = Dynamic;
INSERT INTO `shiro_user` VALUES (1, 'test', '123456');

shiro_user_role表：

DROP TABLE IF EXISTS `shiro_user_role`;
CREATE TABLE `shiro_user_role`  (
  `ID` int(11) NOT NULL AUTO_INCREMENT,
  `USER_NAME` varchar(255) CHARACTER SET latin1 COLLATE latin1_swedish_ci NULL DEFAULT NULL,
  `ROLE_NAME` varchar(255) CHARACTER SET latin1 COLLATE latin1_swedish_ci NULL DEFAULT NULL,
  PRIMARY KEY (`ID`) USING BTREE
) ENGINE = InnoDB AUTO_INCREMENT = 2 CHARACTER SET = latin1 COLLATE = latin1_swedish_ci ROW_FORMAT = Dynamic;
INSERT INTO `shiro_user_role` VALUES (1, 'test', 'role1');

shiro_role_permission表：

DROP TABLE IF EXISTS `shiro_role_permission`;
CREATE TABLE `shiro_role_permission`  (
  `ID` int(11) NOT NULL AUTO_INCREMENT,
  `ROLE_NAME` varchar(255) CHARACTER SET latin1 COLLATE latin1_swedish_ci NULL DEFAULT NULL,
  `PERM_NAME` varchar(255) CHARACTER SET latin1 COLLATE latin1_swedish_ci NULL DEFAULT NULL,
  PRIMARY KEY (`ID`) USING BTREE
) ENGINE = InnoDB AUTO_INCREMENT = 2 CHARACTER SET = latin1 COLLATE = latin1_swedish_ci ROW_FORMAT = Dynamic;
INSERT INTO `shiro_role_permission` VALUES (1, 'role1', 'perm1');

3.4、程序的入口
Application.java类是springBoot程序的入口

@SpringBootApplication
//扫描你项目所有的java类
@ComponentScan(basePackages = {"com.huihui"})
//扫描mapper所在的位置
@MapperScan({"com.huihui.chapter2.mapper"})
public class Application {

    public static void main(String[] args) throws Exception{
        SpringApplication.run(Application.class,args);

    }

}

3.5、开始写接口代码
先看一下项目的结构

image.png

代码从数据库开始写起：

@Repository
public interface UserMapper {

    String queryUserPassword(@Param("userName")String userName);

    List<String> queryUserRole(@Param("userName")String userName);

    List<String> queryRolePermission(@Param("roleName")String roleName);

    List<String> queryUserPermission(@Param("userName")String userName);
}

mapper对应的xml文件：

<?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.huihui.chapter2.mapper.UserMapper">
    <select id="queryUserPassword" resultType="string">
      select password from shiro_user where user_name = #{userName, jdbcType=VARCHAR}
    </select>
    <select id="queryUserRole" resultMap="roleMap">
      select role_name from shiro_user_role where user_name = #{userName, jdbcType=VARCHAR}
    </select>

    <resultMap id="permissionMap" type="java.lang.String">
        <result column="perm_name" jdbcType="VARCHAR"/>
    </resultMap>
    <resultMap id="roleMap" type="java.lang.String">
        <result column="role_name" jdbcType="VARCHAR"/>
    </resultMap>

    <select id="queryUserPermission" resultMap="permissionMap">
      SELECT
        srp.perm_name
          FROM
            shiro_user_role sur
            INNER JOIN shiro_role_permission srp ON sur.role_name = srp.role_name
          WHERE
            sur.user_name = #{userName, jdbcType=VARCHAR}
    </select>
    <select id="queryRolePermission" resultMap="permissionMap">
      select perm_name from shiro_role_permission where role_name = #{roleName, jdbcType=VARCHAR}
    </select>
</mapper>

接下来是service：

@Service
public class UserService {

    @Autowired
    UserMapper userMapper;
    @Autowired
    MyUserRealm myUserRealm;

    /**
     * 登录
     * @param username
     * @param password
     * @throws Exception
     */
    public void doLogin(String username, String password) throws Exception {
        Subject currentUser = SecurityUtils.getSubject();

        if (!currentUser.isAuthenticated()) {
            UsernamePasswordToken token = new UsernamePasswordToken(username, password);
            token.setRememberMe(true);//是否记住用户
            try {
                currentUser.login(token);//执行登录
            } catch (UnknownAccountException uae) {
                throw new Exception("账户不存在");
            } catch (IncorrectCredentialsException ice) {
                throw new Exception("密码不正确");
            } catch (LockedAccountException lae) {
                throw new Exception("用户被锁定了 ");
            } catch (AuthenticationException ae) {
                ae.printStackTrace();
                throw new Exception("未知错误");
            }
        }
    }

    /**
     * 根据用户名查询密码
     * @param userName
     * @return
     */
    public String queryUserPassword(String userName){
        return userMapper.queryUserPassword(userName);
    }

    /**
     * 查询当前用户对应的权限
     * @param userName
     * @return
     */
    public List<String> queryUserPermission(String userName){
        return userMapper.queryUserPermission(userName);
    }

}

controller：

@Controller
public class UserController {

    @Autowired
    UserService userService;

    @RequestMapping(value = "/index",method = RequestMethod.POST)
    public String goLogin() {
        return "/index.html";
    }

    @RequestMapping(value = "/logout",method = RequestMethod.POST)
    public String login() {
        Subject currentUser = SecurityUtils.getSubject();
        currentUser.logout();
        return "/index.html";
    }

    @RequestMapping(value = "/",method = RequestMethod.GET)
    public String index() {
        return "/index.html";
    }

    @RequestMapping(value = "/login",method = RequestMethod.POST)
    public String login(String username, String password) {
        try {
            userService.doLogin(username, password);
        } catch (Exception e) {
            return "redirect:/hello";
        }
        return "redirect:/hello";
    }

    @RequestMapping(value = "/hello")
    public String hello(){
        return "hello.html";
    }

    @RequestMapping(value = "/hello1")
//需要访问此接口的权限
    @RequiresPermissions("perm3")
    public String hello1(){
        return "hello2.html";
    }

}

写一个异常拦截器，拦截没有权限和未登录的异常：

@ControllerAdvice
public class ExceptionInterceptor {

    @ExceptionHandler({ UnauthorizedException.class, AuthorizationException.class })
    public String authorizationException(HttpServletRequest req, HttpServletResponse response, Exception e)  {
        return "没有权限";
    }

    @ExceptionHandler({ UnauthenticatedException.class, AuthenticationException.class })
    public String authenticationException(HttpServletRequest req, HttpServletResponse response, Exception e)  {

        return "请登录";
    }

}

写一个Realm继承AuthorizingRealm，重写获取权限，登录等方法：

public class MyUserRealm extends AuthorizingRealm {

    @Autowired
    UserService userService;

    public AuthorizationInfo queryAuthorizationInfo(PrincipalCollection principals){
        return this.getAuthorizationInfo(principals);
    }

    // 获取用户的权限
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {

        String userName = principals.fromRealm(getName()).iterator().next().toString();
        if(userName != null){
            //获取用户所有权限  根据自己的需求编写获取授权信息，这里简化代码获取了用户对应的所有权限
            List<String> perms = userService.queryUserPermission(userName);
            if(perms != null && !perms.isEmpty()){
                SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();
                for(String each : perms){
                    //将权限添加到用户信息中
                    info.addStringPermission(each);
                }
                return info;
            }
        }

        return null;
    }

    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {

        UsernamePasswordToken token = (UsernamePasswordToken)authenticationToken;
        //通过表单接受的用户名，调用currentUser.login的时候执行
        String userName = token.getUsername();
        if(userName != null && !"".equals(userName)){
            //查询密码
            String password = userService.queryUserPassword(userName);
            if(password != null){
                return new SimpleAuthenticationInfo(userName,password,getName());
            }
        }

        return null;
    }

    @Override
    public void clearCachedAuthorizationInfo(PrincipalCollection principals) {
        super.clearCachedAuthorizationInfo(principals);
    }

    @Override
    public void clearCachedAuthenticationInfo(PrincipalCollection principals) {
        super.clearCachedAuthenticationInfo(principals);
    }

    @Override
    public void clearCache(PrincipalCollection principals) {
        super.clearCache(principals);
    }

}

接下来写一些配置的属性，可以写在配置文件里面，也可以用java类代替，我这边是用java类直接写的：

@Configuration
public class ShiroUserConfig {

    @Bean
    public MyUserRealm myUserRealm(){
        MyUserRealm realm = new MyUserRealm();
        return realm;
    }

    @Bean
    public DefaultWebSecurityManager securityManager(){
        DefaultWebSecurityManager webSecurityManager = new DefaultWebSecurityManager();
        webSecurityManager.setRealm(myUserRealm());
        return webSecurityManager;
    }

    @Bean(name = "shiroFilter")
    public ShiroFilterFactoryBean shiroFilter(){
        ShiroFilterFactoryBean factoryBean = new ShiroFilterFactoryBean();
        factoryBean.setSecurityManager(securityManager());
        // 配置访问权限
        LinkedHashMap<String, String> filterChainDefinitionMap = new LinkedHashMap<>();

        //filterChainDefinitionMap.put("/index", "anon"); // 表示可以匿名访问
//      filterChainDefinitionMap.put("/*", "authc");// 表示需要认证才可以访问
//      filterChainDefinitionMap.put("/user/login", "perms[权限添加]");

        factoryBean.setFilterChainDefinitionMap(filterChainDefinitionMap);
        return factoryBean;
    }


    /***  开启Shiro的注解*/
    @Bean
    public LifecycleBeanPostProcessor lifecycleBeanPostProcessor() {
        return new LifecycleBeanPostProcessor();
    }

    @Bean
    public DefaultAdvisorAutoProxyCreator defaultAdvisorAutoProxyCreator() {
        DefaultAdvisorAutoProxyCreator creator = new DefaultAdvisorAutoProxyCreator();
        creator.setProxyTargetClass(true);
        return creator;
    }

    @Bean
    public AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor() {
        AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor = new AuthorizationAttributeSourceAdvisor();
        authorizationAttributeSourceAdvisor.setSecurityManager(securityManager());
        return authorizationAttributeSourceAdvisor;
    }

OK，接口准备完毕了，接下来写几个简单的页面测试一下：

image.png

index.html

<form method="post" action="/login">
    <div>
        账号: <input type="text" value="test" name="username" id="username" placeholder="账号">
    </div>
    <div>
        密码: <input type="password" value="123456" class="form-control" name="password" id="password" placeholder="密码">
    </div>
    <button type="submit">提交</button>
</form>

hello.html

<form action="/logout" method="post">
    <button type="submit">退出</button>
</form>
<form method="post" action="/hello1">
    <button type="submit">hello2</button>
</form>

hello2.html跟error.html随便写点东西

OK，到这里代码及写完了
