SpringSecurity从入门到精通：登录接口代码实现&测试接口

登录接口代码实现

 

@RestController 

@RestController
public class LoginController {

    @Autowired
    private LoginServcie loginServcie;

    @PostMapping("/user/login")
    public ResponseResult login(@RequestBody User user){
        return loginServcie.login(user);
    }
}

 

 LoginServiceImpl

package com.sangeng.service.Impl;

import com.sangeng.Utils.JwtUtil;
import com.sangeng.Utils.RedisCache;
import com.sangeng.domain.LoginUser;
import com.sangeng.domain.ResponseResult;
import com.sangeng.domain.User;
import com.sangeng.service.LoginService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.authentication.AuthenticationManager;
import org.springframework.security.authentication.UsernamePasswordAuthenticationToken;
import org.springframework.security.core.Authentication;
import org.springframework.stereotype.Service;

import java.util.HashMap;
import java.util.Objects;

@Service
public class LoginServiceImpl implements LoginService {

    @Autowired
    private AuthenticationManager authenticationManager;
    @Autowired
    private RedisCache redisCache;

    @Override
    public ResponseResult login(User user) {
        UsernamePasswordAuthenticationToken authenticationToken = new UsernamePasswordAuthenticationToken(user.getUserName(),user.getPassword());
        Authentication authenticate = authenticationManager.authenticate(authenticationToken);
        if(Objects.isNull(authenticate)){
            throw new RuntimeException("用户名或密码错误");
        }
        //使用userid生成token
        LoginUser loginUser = (LoginUser) authenticate.getPrincipal();
        String userId = loginUser.getUser().getId().toString();
        String jwt = JwtUtil.createJWT(userId);
        //authenticate存入redis
        redisCache.setCacheObject("login:"+userId,loginUser);
        //把token响应给前端
        HashMap<String,String> map = new HashMap<>();
        map.put("token",jwt);
        return new ResponseResult(200,"登陆成功",map);
    }
}

 

Config

package com.sangeng.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.authentication.AuthenticationManager;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.config.http.SessionCreationPolicy;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;


@Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter {


    @Bean
    public PasswordEncoder passwordEncoder(){
        return new BCryptPasswordEncoder();
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
                //关闭csrf
                .csrf().disable()
                //不通过Session获取SecurityContext
                .sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS)
                .and()
                .authorizeRequests()
                // 对于登录接口 允许匿名访问
                .antMatchers("/user/login").anonymous()
                // 除上面外的所有请求全部需要鉴权认证
                .anyRequest().authenticated();
    }

    @Bean
    @Override
    public AuthenticationManager authenticationManagerBean() throws Exception {
        return super.authenticationManagerBean();
    }
}
