Springboot整合Shiro

标签：ack   pass   security   过滤   efi   用户输入   pen   获得   filter   

1、导入依赖

<!--shiro-->
<dependency>
    <groupId>org.apache.shiro</groupId>
    <artifactId>shiro-spring</artifactId>
    <version>1.4.0</version>
</dependency>

2、创建ShiroRealm.java文件

（这里按照需求，只做登录认证这块）

package com.hyqfx.manager.shiro;

import com.baomidou.mybatisplus.mapper.EntityWrapper;
import com.hyqfx.manager.entity.po.SystemAdmin;
import com.hyqfx.manager.service.ISystemAdminService;
import org.apache.shiro.authc.*;
import org.apache.shiro.authz.AuthorizationInfo;
import org.apache.shiro.realm.AuthorizingRealm;
import org.apache.shiro.subject.PrincipalCollection;
import org.springframework.beans.factory.annotation.Autowired;

public class ShiroRealm extends AuthorizingRealm {

    @Autowired
    private ISystemAdminService adminService;

    //授权
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
        /*
        //获取登录用户名
        String name= (String) principalCollection.getPrimaryPrincipal();
        //查询用户名称
        User user = loginService.findByName(name);
        //添加角色和权限
        SimpleAuthorizationInfo simpleAuthorizationInfo = new SimpleAuthorizationInfo();
        for (Role role:user.getRoles()) {
            //添加角色
            simpleAuthorizationInfo.addRole(role.getRoleName());
            for (Permission permission:role.getPermissions()) {
                //添加权限
                simpleAuthorizationInfo.addStringPermission(permission.getPermission());
            }
        }
        return simpleAuthorizationInfo;*/


        return null;
    }

    //认证
    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
        //加这一步的目的是在Post请求的时候会先进认证，然后在到请求
        if (authenticationToken.getPrincipal() == null) {
            return null;
        }
        //获取用户信息
        String name = authenticationToken.getPrincipal().toString(); 
        SystemAdmin admin = adminService.selectOne(new EntityWrapper<SystemAdmin>().eq("username",name));

        if (admin == null) {
            return null;
        } else {
            //这里验证authenticationToken和simpleAuthenticationInfo的信息
            SimpleAuthenticationInfo simpleAuthenticationInfo = new SimpleAuthenticationInfo(name, admin.getPassword().toString(), getName());
            return simpleAuthenticationInfo;
        }
    }

}

3、创建ShiroConfiguration.java文件

package com.becl.config;

import com.becl.shiro.PasswordMatcher;
import com.becl.shiro.ShiroRealm;
import org.apache.shiro.mgt.SecurityManager;
import org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor;
import org.apache.shiro.spring.web.ShiroFilterFactoryBean;
import org.apache.shiro.web.mgt.DefaultWebSecurityManager;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import java.util.HashMap;
import java.util.Map;

@Configuration
public class ShiroConfiguration {



    //将自己的验证方式加入容器
    @Bean
    public ShiroRealm myShiroRealm() {
        ShiroRealm myShiroRealm = new ShiroRealm();
        myShiroRealm.setCredentialsMatcher(passwordMatcher());//装配自定义的密码验证方式
        return myShiroRealm;
    }

    // 配置加密方式
    // 配置了一下，这货就是验证不过，，改成手动验证算了，以后换加密方式也方便
    @Bean
    public PasswordMatcher passwordMatcher() {
        return new PasswordMatcher();
    }

    //权限管理，配置主要是Realm的管理认证
    @Bean
    public SecurityManager securityManager() {
        DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
        securityManager.setRealm(myShiroRealm());
        return securityManager;
    }

    //Filter工厂，设置对应的过滤条件和跳转条件
    @Bean
    public ShiroFilterFactoryBean shiroFilterFactoryBean(SecurityManager securityManager) {
        ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();
        shiroFilterFactoryBean.setSecurityManager(securityManager);
        Map<String,String> map = new HashMap<String, String>();
        //登出
        map.put("/logout","logout");
        //不需要认证
        map.put("/logout","anon");
        map.put("/login*","anon");
        map.put("/shiroError","anon");
        //对所有用户认证
        map.put("/**","authc");
        //map.put("/**","anon");
        //登录
        shiroFilterFactoryBean.setLoginUrl("/login");
        //首页
        shiroFilterFactoryBean.setSuccessUrl("/index");
        //错误页面，认证不通过跳转
        shiroFilterFactoryBean.setUnauthorizedUrl("/shiroError");
        shiroFilterFactoryBean.setFilterChainDefinitionMap(map);
        return shiroFilterFactoryBean;
    }

    //加入注解的使用，不加入这个注解不生效
    @Bean
    public AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor(SecurityManager securityManager) {
        AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor = new AuthorizationAttributeSourceAdvisor();
        authorizationAttributeSourceAdvisor.setSecurityManager(securityManager);
        return authorizationAttributeSourceAdvisor;
    }

}

4、自定义Shiro的密码比较器

package com.becl.shiro;

import org.apache.shiro.authc.AuthenticationInfo;
import org.apache.shiro.authc.AuthenticationToken;
import org.apache.shiro.authc.UsernamePasswordToken;
import org.apache.shiro.authc.credential.SimpleCredentialsMatcher;
import org.mindrot.jbcrypt.BCrypt;

/**
 * 自定义密码比较器
 */
public class PasswordMatcher extends SimpleCredentialsMatcher {


    @Override
    public boolean doCredentialsMatch(AuthenticationToken token, AuthenticationInfo info) {
        UsernamePasswordToken utoken=(UsernamePasswordToken) token;

        //获得用户输入的密码:(可以采用加盐(salt)的方式去检验)
        String inPassword = new String(utoken.getPassword());
        String username = utoken.getUsername();

        //获得数据库中的密码
        String dbPassword = (String) info.getCredentials();


        //进行密码的比对
        boolean flag = BCrypt.checkpw(inPassword,dbPassword);
        return flag;
    }

}
