【微服务｜Spring Security⑧】Spring Security实现授权功能

实现授权需要对用户的访问进行拦截校验，校验用户的权限是否可以操作指定的资源，Spring Security默认提供授权实现方法。

在LoginController 添加/r/r1 或/r/r2

package com.uncle.security.springmvc.controller;

import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.bind.annotation.RestController;

import javax.servlet.http.HttpSession;

/**
 * @program: security-springmvc
 * @description:
 * @author: 步尔斯特
 * @create: 2021-07-22 23:33
 */
@RestController
public class LoginController {
    
    

    @RequestMapping(value = "/login-success",produces = {
    
    "text/plain;charset=UTF-8"})
    public String loginSuccess(){
    
    
        return " 登录成功";
    }

    /**
     * 测试资源1
     * @return
     */
    @GetMapping(value = "/r/r1",produces = {
    
    "text/plain;charset=UTF-8"})
    public String r1(){
    
    
        return " 访问资源1";
    }

    /**
     * 测试资源2
     * @return
     */
    @GetMapping(value = "/r/r2",produces = {
    
    "text/plain;charset=UTF-8"})
    public String r2(){
    
    
        return " 访问资源2";
    }
}

在安全配置类WebSecurityConfig.java中配置授权规则:

package com.uncle.security.springmvc.config;

import org.springframework.context.annotation.Bean;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.core.userdetails.User;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.crypto.password.NoOpPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;
import org.springframework.security.provisioning.InMemoryUserDetailsManager;

/**
 * @program: spring-security-springmvc
 * @description:
 * @author: 步尔斯特
 * @create: 2021-07-23 00:41
 */
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
    
    

    //定义用户信息服务（查询用户信息）
    @Bean
    public UserDetailsService userDetailsService(){
    
    
        InMemoryUserDetailsManager manager = new InMemoryUserDetailsManager();
        manager.createUser(User.withUsername("zhangsan").password("123").authorities("p1").build());
        manager.createUser(User.withUsername("lisi").password("456").authorities("p2").build());
        return manager;
    }

    //密码编码器
    @Bean
    public PasswordEncoder passwordEncoder(){
    
    
        return NoOpPasswordEncoder.getInstance();
    }

    //安全拦截机制（最重要）
    @Override
    protected void configure(HttpSecurity http) throws Exception {
    
    
        http.authorizeRequests()
                .antMatchers("/r/r1").hasAuthority("p1")
                .antMatchers("/r/r2").hasAuthority("p2")
                .antMatchers("/r/**").authenticated()//所有/r/**的请求必须认证通过
                .anyRequest().permitAll()//除了/r/**，其它的请求可以访问
                .and()
                .formLogin()//允许表单登录
                .successForwardUrl("/login-success");//自定义登录成功的页面地址

    }
}

测试

登录成功

访问/r/r1和/r/r2 ,有权限时则正常访问,否则返回403 (拒绝访问)
