基于SpringBoot2的Shiro最简配置操作(两个文件)

作者：苍穹之跃

这篇文章主要介绍了基于SpringBoot2的Shiro最简配置操作(两个文件)，具有很好的参考价值，希望对大家有所帮助。一起跟随小编过来看看吧

基础环境：依赖

<parent>
 <groupId>org.springframework.boot</groupId>
 <artifactId>spring-boot-starter-parent</artifactId>
 <version>2.2.1.RELEASE</version>
 <relativePath/> <!-- lookup parent from repository -->
</parent>
<dependency>
 <groupId>org.apache.shiro</groupId>
 <artifactId>shiro-spring-boot-starter</artifactId>
 <version>1.4.0</version>
</dependency>

如果不是前后端分离，要实现页面级的权限控制，则加入以下依赖就可以使用shiro的权限标签了（记得在html头部加上相应约束：

<html xmlns="http://www.w3.org/1999/xhtml" xmlns:th="Thymeleaf" xmlns:shiro="http://www.pollix.at/thymeleaf/shiro"
  lang="en">
）：
<dependency>
 <groupId>com.github.theborakompanioni</groupId>
 <artifactId>thymeleaf-extras-shiro</artifactId>
 <version>2.0.0</version>
</dependency>

Realm：认证鉴权器

package com.rz.monomer.modules.shiro; 
import com.baomidou.mybatisplus.core.conditions.query.LambdaQueryWrapper;
import com.rz.monomer.modules.user.entity.SysUserInfo;
import com.rz.monomer.modules.user.entity.SysUserRole;
import com.rz.monomer.modules.user.service.SysButtonInfoService;
import com.rz.monomer.modules.user.service.SysUserInfoService;
import com.rz.monomer.modules.user.service.SysUserRoleService;
import lombok.extern.slf4j.Slf4j;
import org.apache.shiro.authc.AuthenticationException;
import org.apache.shiro.authc.AuthenticationInfo;
import org.apache.shiro.authc.AuthenticationToken;
import org.apache.shiro.authc.SimpleAuthenticationInfo;
import org.apache.shiro.authz.AuthorizationInfo;
import org.apache.shiro.authz.SimpleAuthorizationInfo;
import org.apache.shiro.realm.AuthorizingRealm;
import org.apache.shiro.subject.PrincipalCollection; 
import java.util.Set;
import java.util.stream.Collectors;
 
/**
 * 认证、鉴权类（必须）
 *
 * @author sunziwen
 * @version 1.0
 * @date 2019/11/14 14:06
 **/
@Slf4j
public class ShiroRealm extends AuthorizingRealm {
 //以下三个服务是普通Dao查询，从数据库查询用户及其角色权限信息（这个类没有自动注入，需要在下个文件中手动注入）
 private SysUserInfoService userInfoService;
 private SysButtonInfoService buttonInfoService;
 private SysUserRoleService userRoleService;
 
 public ShiroRealm(SysUserInfoService userInfoService, SysButtonInfoService buttonInfoService, SysUserRoleService userRoleService) {
  this.userInfoService = userInfoService;
  this.buttonInfoService = buttonInfoService;
  this.userRoleService = userRoleService;
 }
 
 @Override
 protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
  log.info("check authorization info");
 
  SimpleAuthorizationInfo authInfo = new SimpleAuthorizationInfo();
 
  // 获取当前用户
  SysUserInfo userInfo = (SysUserInfo) principals.getPrimaryPrincipal();
 
  // 查询角色信息
  Set<Long> userRoles = userRoleService.list(new LambdaQueryWrapper<SysUserRole>().eq(SysUserRole::getUserId, userInfo.getId()))
            .stream()
            .map(SysUserRole::getRoleId)
            .collect(Collectors.toSet());
  //角色所有权限
  Set<String> perms = buttonInfoService.getPermsByRoles(userRoles);
  authInfo.addStringPermissions(perms);
  return authInfo;
 }
 
 @Override
 protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
  log.info("check authentication info");
 
  String username = (String) token.getPrincipal();
 
  // 获取用户信息
  SysUserInfo user = userInfoService.getOne(new LambdaQueryWrapper<SysUserInfo>().eq(SysUserInfo::getUsername, username));
 
  if (user == null) {
   return null;
  }
 
  /*SimpleAuthenticationInfo authenticationInfo = new SimpleAuthenticationInfo(user, user.getPassword(),
    ByteSource.Util.bytes(654321), getName());*/
 
  SimpleAuthenticationInfo authenticationInfo = new SimpleAuthenticationInfo(user, user.getPassword(), getName());
  return authenticationInfo;
 }
}

WebSecurityManager：安全管理器

package com.rz.monomer.modules.shiro; 
import com.rz.monomer.modules.user.service.SysButtonInfoService;
import com.rz.monomer.modules.user.service.SysUserInfoService;
import com.rz.monomer.modules.user.service.SysUserRoleService;
import lombok.AllArgsConstructor;
import lombok.extern.slf4j.Slf4j;
import org.apache.shiro.spring.web.ShiroFilterFactoryBean;
import org.apache.shiro.web.filter.authc.FormAuthenticationFilter;
import org.apache.shiro.web.filter.authc.LogoutFilter;
import org.apache.shiro.web.mgt.DefaultWebSecurityManager;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration; 
import javax.servlet.Filter;
import java.util.LinkedHashMap;
import java.util.Map;
 
/**
 * Shiro配置类（必须）
 *
 * @author sunziwen
 * @version 1.0
 * @date 2019/11/14 14:08
 **/
@Configuration
@Slf4j
@AllArgsConstructor
public class WebSecurityManager {
 private SysUserInfoService userInfoService;
 private SysButtonInfoService buttonInfoService;
 private SysUserRoleService userRoleService;
 
 /**
  * 安全管理器
  */
 @Bean
 public DefaultWebSecurityManager securityManager() {
  DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
  securityManager.setRealm(realm());
  return securityManager;
 }
 
 /**
  * 认证鉴权器（安全管理器的依赖）
  */
 @Bean
 public ShiroRealm realm() {
  return new ShiroRealm(userInfoService, buttonInfoService, userRoleService);
 }
 
 /**
  * 配置拦截规则
  */
 @Bean
 public ShiroFilterFactoryBean filter(org.apache.shiro.mgt.SecurityManager securityManager) {
  log.info("config shiro filter");
  ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();
  shiroFilterFactoryBean.setSecurityManager(securityManager);
 
  // 定义URL拦截链
  Map<String, String> filterChainDefinitionMap = new LinkedHashMap<String, String>();
  // 允许匿名用户访问首页
  filterChainDefinitionMap.put("/shiro/index", "anon");
  // 定义注销路径
  filterChainDefinitionMap.put("/shiro/logout", "logout");
  // 所有用户界面都需要身份验证，否则会跳转到loginurl，由FormAuthenticationFilter处理
  filterChainDefinitionMap.put("/shiro/user/**", "authc");
  // 为login路径定义拦截，由FormAuthenticationFilter处理
  filterChainDefinitionMap.put("/shiro/login", "authc");
  // 所有vip路径要求具备vip角色权限
  filterChainDefinitionMap.put("/shiro/vip/**", "roles[vip]");
  // 指定loginurl 路径
  shiroFilterFactoryBean.setLoginUrl("/shiro/login");
  // 登录成功后跳转路径
  shiroFilterFactoryBean.setSuccessUrl("/shiro/user/");
  // for un authenticated
  shiroFilterFactoryBean.setUnauthorizedUrl("/shiro/unauth");
  shiroFilterFactoryBean.setFilterChainDefinitionMap(filterChainDefinitionMap);
 
  // 自定义filters，可覆盖默认的Filter列表，参考 DefaultFilter
  Map<String, Filter> filters = new LinkedHashMap<String, Filter>();
 
  // 定制logout 过滤，指定注销后跳转到登录页(默认为根路径)
  LogoutFilter logoutFilter = new LogoutFilter();
  logoutFilter.setRedirectUrl("/shiro/login");
  filters.put("logout", logoutFilter);
 
  // 定制authc 过滤，指定登录表单参数
  FormAuthenticationFilter authFilter = new FormAuthenticationFilter();
  authFilter.setUsernameParam("username");
  authFilter.setPasswordParam("password");
  filters.put("authc", authFilter);
 
  shiroFilterFactoryBean.setFilters(filters);
  return shiroFilterFactoryBean;
 }
}

Test：登录测试

package com.rz.monomer.modules.user.controller; 
import com.rz.monomer.commons.utils.Md5Encrypt;
import lombok.extern.slf4j.Slf4j;
import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.*;
import org.apache.shiro.authz.annotation.RequiresAuthentication;
import org.apache.shiro.subject.Subject;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.*; 
@RestController
@Slf4j
public class LoginController { 
 @PostMapping("/login")
 public String login(@RequestParam("username") String username, @RequestParam("password") String password) {
  Subject subject = SecurityUtils.getSubject();
  AuthenticationToken token = new UsernamePasswordToken(username, Md5Encrypt.md5(password));
 
  try {
   // 执行登录
   subject.login(token);
 
  } catch (UnknownAccountException e) {
 
   // 未知用户
   log.warn("the account {} is not found", username);
 
   return "account not found";
  } catch (IncorrectCredentialsException e) {
 
   // 用户或密码不正确
   log.warn("the account or password is not correct");
   return "account or password not correct";
 
  }
  return "login success";
 }
 
}

补充：SpringBoot配置Shiro时踩坑

在SpringBoot2.0整合shiro时使用@EnableAutoConfiguration的时候需要对config文件进行扫描，即使用@ComponentScan对配置进行扫描。

或者直接使用@SpringBootApplication,但是这种方法会将主方法目录下的所有package都进行扫描影响项目效率。

Authentication failed for token submission [org.apache.shiro.authc.UsernamePasswordToken - zxc, rememberMe=false]. Possible unexpected error? (Typical or expected login exceptions should extend from AuthenticationException

当出现此异常时，一般情况是用户名密码不匹配，或者是在配置对应的Realm时出现空值导致匹配失败。

以上为个人经验，希望能给大家一个参考，也希望大家多多支持脚本之家。如有错误或未考虑完全的地方，望不吝赐教。
