基于SpringBoot2的Shiro最简配置操作(两个文件)

2023-07-06 09:04:03 161

基础环境：依赖


org.springframework.boot
spring-boot-starter-parent
2.2.1.RELEASE


org.apache.shiro
shiro-spring-boot-starter
1.4.0

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：


）：

com.github.theborakompanioni
thymeleaf-extras-shiro
2.0.0

Realm：认证鉴权器

WebSecurityManager：安全管理器

Test：登录测试

packagecom.rz.monomer.modules.user.controller;
importcom.rz.monomer.commons.utils.Md5Encrypt;
importlombok.extern.slf4j.Slf4j;
importorg.apache.shiro.SecurityUtils;

importorg.apache.shiro.subject.Subject;
importorg.springframework.stereotype.Controller;
importorg.springframework.web.bind.annotation.*;
@RestController
@Slf4j
publicclassLoginController{
@PostMapping("/login")
publicStringlogin(@RequestParam("username")Stringusername,@RequestParam("password")Stringpassword){
Subjectsubject=SecurityUtils.getSubject();
AuthenticationTokentoken=newUsernamePasswordToken(username,Md5Encrypt.md5(password));

try{
//执行登录
subject.login(token);

}catch(UnknownAccountExceptione){

//未知用户
log.warn("theaccount{}isnotfound",username);

return"accountnotfound";
}catch(IncorrectCredentialsExceptione){

//用户或密码不正确
log.warn("theaccountorpasswordisnotcorrect");
return"accountorpasswordnotcorrect";

}
return"loginsuccess";
}

}

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。

Authenticationfailedfortokensubmission[org.apache.shiro.authc.UsernamePasswordToken-zxc,rememberMe=false].Possibleunexpectederror?(TypicalorexpectedloginexceptionsshouldextendfromAuthenticationException

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毛票票。如有错误或未考虑完全的地方，望不吝赐教。
