4.mybatis分頁外掛

@Configuration
public class MybatisPlusConfig {

    /**
     * 分頁外掛
     */
    @Bean
    public PaginationInterceptor paginationInterceptor() {
        return new PaginationInterceptor();
    }
}

5.新增shiro配置類

@Configuration
public class ShiroConfig {

    @Bean
    public ShiroFilterFactoryBean shirFilter(SecurityManager securityManager) {
        ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();
        // 必須設定 SecurityManager
        shiroFilterFactoryBean.setSecurityManager(securityManager);
        // setLoginUrl 如果不設定值，預設會自動尋找Web工程根目錄下的"/login.jsp"頁面 或 "/login" 對映
        shiroFilterFactoryBean.setLoginUrl("/notLogin");
        // 設定無許可權時跳轉的 url;
        shiroFilterFactoryBean.setUnauthorizedUrl("/notRole");

        // 設定攔截器
        Map<String, String> filterChainDefinitionMap = new LinkedHashMap<>();
        //開放登陸介面
        filterChainDefinitionMap.put("/login", "anon");
        //其餘介面一律攔截
        //主要這行程式碼必須放在所有許可權設定的最後，不然會導致所有 url 都被攔截
        filterChainDefinitionMap.put("/**", "authc");

        shiroFilterFactoryBean.setFilterChainDefinitionMap(filterChainDefinitionMap);
        System.out.println("Shiro攔截器工廠類注入成功");
        return shiroFilterFactoryBean;
    }

    /**
     * 注入 securityManager
     */
    @Bean
    public SecurityManager securityManager() {
        DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
        // 設定realm.
        securityManager.setRealm(customRealm());
        return securityManager;
    }

    /**
     * 自定義身份認證 realm;
     * <p>
     * 必須寫這個類，並加上 @Bean 註解，目的是注入 CustomRealm，
     * 否則會影響 CustomRealm類 中其他類的依賴注入
     */
    @Bean
    public CustomRealm customRealm() {
        return new CustomRealm();
    }

    /**
     *  開啟Shiro的註解(如@RequiresRoles,@RequiresPermissions)
     * @return
     */
    @Bean
    public DefaultAdvisorAutoProxyCreator advisorAutoProxyCreator(){
        DefaultAdvisorAutoProxyCreator advisorAutoProxyCreator = new DefaultAdvisorAutoProxyCreator();
        advisorAutoProxyCreator.setProxyTargetClass(true);
        return advisorAutoProxyCreator;
    }

    /**
     * 開啟aop註解支援
     * @param securityManager
     * @return
     */
    @Bean
    public AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor(SecurityManager securityManager) {
        AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor = new AuthorizationAttributeSourceAdvisor();
        authorizationAttributeSourceAdvisor.setSecurityManager(securityManager);
        return authorizationAttributeSourceAdvisor;
    }
}

6.建立CustomRealm用於使用者驗證和許可權控制

public class CustomRealm extends AuthorizingRealm {

    @Autowired
    private ISysUserService userService;

    @Autowired
    private ISysPermissionService sysPermissionService;

    /**
     * 獲取身份驗證資訊
     * Shiro中，最終是通過 Realm 來獲取應用程式中的使用者、角色及許可權資訊的。
     *
     * @param authenticationToken 使用者身份資訊 token
     * @return 返回封裝了使用者資訊的 AuthenticationInfo 例項
     */
    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
        System.out.println("————身份認證方法————");
        String password = "";
        UsernamePasswordToken token = (UsernamePasswordToken) authenticationToken;
        // 從資料庫獲取對應使用者名稱密碼的使用者
        QueryWrapper query = new QueryWrapper();
        query.eq("user_name",token.getUsername());
        SysUser user = userService.getOne(query);
        if (user != null){
            password = user.getPassword();
            if (null == password) {
                throw new AccountException("使用者名稱不正確");
            } else if (!password.equals(new String((char[]) token.getCredentials()))) {
                throw new AccountException("密碼不正確");
            }
        }else {
            throw new AccountException("該使用者不存在");
        }
        // 第一個引數儲存為當前登陸人資訊就可以使用 SecurityUtils.getSubject().getPrincipal() 獲取登陸人資訊
        return new SimpleAuthenticationInfo(user, password, getName());
    }

    /**
     * 獲取授權資訊
     *
     * @param principalCollection
     * @return
     */
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
        System.out.println("————許可權認證————");
        String username = (String) SecurityUtils.getSubject().getPrincipal();
        SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();
        //獲得該使用者角色
        Set<SysRole> sets = userService.getRole(username);

        Set<String> set = sets.stream().map(SysRole::getRoleCode).collect(Collectors.toSet());
        Set<Integer> roleIds = sets.stream().map(SysRole::getId).collect(Collectors.toSet());
        //設定該使用者擁有的角色
        info.setRoles(set);
        Set<String> permissionSet = sysPermissionService.getPermissionByRole(roleIds);
        info.setStringPermissions(permissionSet);
        return info;
    }
}

7.service
ISysUserService

public interface ISysUserService extends IService<SysUser> {

    Set<SysRole> getRole(String username);
}

ISysPermissionService

public interface ISysPermissionService extends IService<SysPermission> {

    Set<String> getPermissionByRole(Set<Integer> sets);

        return userMapper.getRole(username);
    }
}

ISysPermissionServiceImpl

@Service

    @Override
    public Set<String> getPermissionByRole(Set<Integer> sets) {
        return sysPermissionMapper.getPermissionByRole(sets);
    }
}

9.mapper
ISysUserMapper

@Repository
@Mapper
public interface SysUserMapper extends BaseMapper<SysUser> {

    Set<SysRole> getRole(String username);
}

ISysPermissionMapper

@Repository
@Mapper
public interface SysPermissionMapper extends BaseMapper<SysPermission> {

    Set<String> getPermissionByRole(@Param("set") Set<Integer> sets);

12.編寫登入controller

package com.example.controller;

import com.example.result.ResultInfo;
import com.example.result.Status;
import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.UsernamePasswordToken;
import org.apache.shiro.subject.Subject;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;

/**
 * @author zk
 * @Classname LoginController
 * @Description TODO
 * @Date 2021/6/11 17:17
 */
@RestController
public class LoginController {

    @RequestMapping(value = "/notLogin", method = RequestMethod.GET)
    public ResultInfo notLogin() {
        return new ResultInfo(Status.SUCCESS.code,"您尚未登陸！");
    }

    @RequestMapping(value = "/notRole", method = RequestMethod.GET)
    public ResultInfo notRole() {
        return new ResultInfo(Status.SUCCESS.code,"您沒有許可權！");
    }

    @RequestMapping(value = "/logout", method = RequestMethod.GET)
    public ResultInfo logout() {
        Subject subject = SecurityUtils.getSubject();
        //登出
        subject.logout();
        return new ResultInfo(Status.SUCCESS.code,"成功登出！");
    }

    /**
     * 登陸
     *
     * @param username 使用者名稱
     * @param password 密碼
     */
    @RequestMapping(value = "/login", method = RequestMethod.POST)
    public ResultInfo login(String username, String password) {
        // 從SecurityUtils裡邊建立一個 subject
        Subject subject = SecurityUtils.getSubject();

        UsernamePasswordToken token = new UsernamePasswordToken(username, password);
        // 執行認證登陸
        subject.login(token);
        return new ResultInfo(Status.SUCCESS.code,"登入成功");
    }
}

13.編寫異常處理ExceptionController

package com.example.controller;

import com.example.result.ResultInfo;
import com.example.result.Status;
import org.apache.shiro.authc.AccountException;
import org.apache.shiro.authz.UnauthorizedException;
import org.springframework.beans.factory.annotation.Autowired;

public class ExceptionController {

    @Autowired
    private ResultInfo resultInfo;

    @Autowired
    public ExceptionController(ResultInfo resultMap) {
        this.resultInfo = resultMap;
    }

    // 捕捉 CustomRealm 丟擲的異常
    @ExceptionHandler(AccountException.class)
    public ResultInfo handleShiroException(Exception ex) {
        return new ResultInfo(Status.SYSTEM_ERROR.code,ex.getMessage());
    }

    /**
     * 訪問介面沒有許可權
     * @param e
     * @return
     */
    @ExceptionHandler(UnauthorizedException.class)
    public ResultInfo handleShiroException1(Exception e) {
        return new ResultInfo(Status.INSUFFICIENT_PERMISSION.code,e.getMessage()+"---"+Status.INSUFFICIENT_PERMISSION.message);
    }
}

14.返回結果封裝類以及返回碼列舉類

        super();
        this.code = code;
        this.message = message;
    }

    /**

        this.code = code;
        this.result = result;
    }

    /**

public enum Status {

    // 公共
    SUCCESS(2000, "成功"),
    UNKNOWN_ERROR(9998,"未知異常"),
    SYSTEM_ERROR(9999, "系統異常"),


    INSUFFICIENT_PERMISSION(4003, "許可權不足"),

    WARN(9000, "失敗"),
    REQUEST_PARAMETER_ERROR(1002, "請求引數錯誤"),

    // 登入
    LOGIN_EXPIRE(2001, "未登入或者登入失效"),
