咱们先来普及一下什么是shiro，shiro原名apache shiro 是一个java 的安全（权限）框架。shiro 可以非常容易的开发出足够好的应用，其不仅可以用在javase环境，也可以用在javaee环境。shiro可以完成，认证，授权，加密，会话管理，web集成，缓存等高级应用。如图看shiro的功能和架构图：
话不多说，Springboot整合shiro,咱们直接上代码
pom.xml文件
4.0.0 org.springframework.boot spring-boot-starter-parent 2.6.11 com.example demo02 0.0.1-SNAPSHOT demo02 demo02 1.8 org.apache.shiro shiro-spring 1.4.1 org.mybatis.spring.boot mybatis-spring-boot-starter 2.1.0 mysql mysql-connector-java 8.0.31 log4j log4j 1.2.17 com.alibaba druid 1.1.12 org.projectlombok lombok 1.18.18 compile org.springframework.boot spring-boot-starter-thymeleaf org.thymeleaf thymeleaf org.thymeleaf.extras thymeleaf-extras-java8time org.springframework.boot spring-boot-starter-web org.springframework.boot spring-boot-starter-test test com.github.theborakompanioni thymeleaf-extras-shiro 2.0.0 org.apache.maven.plugins maven-compiler-plugin 3.8.1 1.8 1.8 UTF-8 org.springframework.boot spring-boot-maven-plugin
然后我们建立一个数据库 /*

– Table structure for user
DROP TABLE IF EXISTS user;
CREATE TABLE user (id int NOT NULL AUTO_INCREMENT,name varchar(255) DEFAULT NULL,pwd varchar(255) DEFAULT NULL,perms varchar(100) DEFAULT NULL,
PRIMARY KEY (id)
) ENGINE=InnoDB AUTO_INCREMENT=4 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_0900_ai_ci;
– Records of user
INSERT INTO user VALUES (‘1’, ‘qin’, ‘d1b129656359e35e95ebd56a63d7b9e0’, ‘user:add’);
INSERT INTO user VALUES (‘2’, ‘hai’, ‘123’, ‘user:insert’);

model.addAttribute("msg","用户名不存在");

}
}
}pojo层User
package com.example.demo02.pojo;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
@Data
@AllArgsConstructor
@NoArgsConstructor
public class User {
private int id;
private String name;
private String pwd;
private String perms;
}config层配置两个类
第一个类ShiroConfig
package com.example.demo02.config;
import at.pollux.thymeleaf.shiro.dialect.ShiroDialect;
import org.apache.shiro.authc.credential.HashedCredentialsMatcher;
import org.apache.shiro.spring.web.ShiroFilterFactoryBean;
import org.apache.shiro.web.mgt.DefaultWebSecurityManager;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import java.util.LinkedHashMap;
import java.util.Map;
//声明为配置类
@Configuration
public class ShiroConfig {
//创建 ShiroFilterFactoryBean
@Bean
public ShiroFilterFactoryBean
getShiroFilterFactoryBean(@Qualifier("securityManager")DefaultWebSecurityManager securityManager){
ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();
//设置安全管理器
shiroFilterFactoryBean.setSecurityManager(securityManager);
/*
添加Shiro内置过滤器，常用的有如下过滤器：
anon： 无需认证就可以访问
authc： 必须认证才可以访问
user： 如果使用了记住我功能就可以直接访问
perms: 拥有某个资源权限才可以访问
role： 拥有某个角色权限才可以访问
*
/
*/
//进行一个拦截
Map filterMap = new LinkedHashMap();
// filterMap.put("/user/add","authc");
// filterMap.put("/user/update","authc");
//授权
// filterMap.put("/user/add","perms[user:add]"); //大家记得注意顺序！
filterMap.put("/user/add","perms[user:add]");
filterMap.put("/user/update","perms[user:update]");
filterMap.put("/user/*","authc");
shiroFilterFactoryBean.setFilterChainDefinitionMap(filterMap);
shiroFilterFactoryBean.setLoginUrl("/toLogin");
//未授权页面
shiroFilterFactoryBean.setUnauthorizedUrl("/noauth");
return shiroFilterFactoryBean;
}
//创建 DefaultWebSecurityManager
@Bean(name = "securityManager")
public DefaultWebSecurityManager
getDefaultWebSecurityManager(@Qualifier("userRealm")UserRealm userRealm){
DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
//2创建加密对象，设置相关属性
HashedCredentialsMatcher matcher = new HashedCredentialsMatcher();
//2.1采用md5加密
matcher.setHashAlgorithmName("md5");
//2.2迭代加密次数
matcher.setHashIterations(3);
//3将加密对象存储到myRealm中
userRealm.setCredentialsMatcher(matcher);
//关联Realm
securityManager.setRealm(userRealm);
return securityManager;
}
//创建 realm 对象
@Bean
public UserRealm userRealm(){
return new UserRealm();
}
//配置ShiroDialect：方言，用于 thymeleaf 和 shiro 标签配合使用
@Bean
public ShiroDialect getShiroDialect(){
return new ShiroDialect();
}
} UserRealm
package com.example.demo02.config;
import com.example.demo02.pojo.User;
import com.example.demo02.service.UserService;
import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.*;
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 org.apache.shiro.subject.Subject;
import org.apache.shiro.util.ByteSource;
import org.springframework.beans.factory.annotation.Autowired;
import java.util.List;
//自定义得UserRaelm
public class UserRealm extends AuthorizingRealm {
@Autowired
UserService userService;
//授权
@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
System.out.println("执行了=》授权doGetAuthorizationInfo");
SimpleAuthorizationInfo info=new SimpleAuthorizationInfo();
// info.addStringPermission("user:update");
info.addStringPermission("user:add");
//拿到当前用户登陆对象
Subject subject= SecurityUtils.getSubject();
User currentUser= (User) subject.getPrincipal();//拿到User对象
info.addStringPermission(currentUser.getPerms());//设置当前用户对象
return info;
}
//执行认证逻辑
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
System.out.println("执行了=>认证逻辑AuthenticationToken");
//假设数据库的用户名和密码
// String name = "root";
// String password = "123456";
//1.判断用户名
UsernamePasswordToken userToken = (UsernamePasswordToken)token;
//连接真实的数据库
User user= userService.queryUserByName(userToken.getUsername());
//
if(user==null){
return null;
}
Subject subject = SecurityUtils.getSubject();
subject.getSession().setAttribute("loginUser",user);
//2. 验证密码,我们可以使用一个AuthenticationInfo实现类SimpleAuthenticationInfo
// shiro会自动帮我们验证！重点是第二个参数就是要验证的密码！
return new SimpleAuthenticationInfo(user, user.getPwd(),ByteSource.Util.bytes("salt"),"");
// if(user !=null){
// AuthenticationInfo info = new SimpleAuthenticationInfo(
// token.getPrincipal(),
// user.getPwd(),
// ByteSource.Util.bytes("salt"),
// token.getPrincipal().toString()
// );
// return info;
// }
// return null;
}
}service层
先是类UserServiceImpl
package com.example.demo02.service;
import com.example.demo02.mapper.UserMapper;
import com.example.demo02.pojo.User;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
@Service
public class UserServiceImpl implements UserService {
@Autowired
UserMapper userMapper;
@Override
public User queryUserByName(String name) {
return userMapper.queryUserByName(name);
}
}再是接口UserService
package com.example.demo02.service;
import com.example.demo02.pojo.User;
public interface UserService {
public User queryUserByName(String name);
}mapper层
接口Usermapper
package com.example.demo02.mapper;
import com.example.demo02.pojo.User;
import org.apache.ibatis.annotations.Mapper;
import org.apache.ibatis.annotations.Param;
import org.apache.ibatis.annotations.Select;
import org.springframework.stereotype.Repository;
@Repository
//@Mapper
public interface UserMapper {
@Select("select * from user where name=#{name}")
public User queryUserByName(@Param("name") String name);
}再就是前端resources里面的static和templates
后端实现鉴权图
存入数据库的数据为加密文件
