springSecurity 学习（一）创建springSecurity项目

创建springsecurity项目的方式有很多，最简单的是 使用Spring Initializr工具，

点击下一步，输入项目基本信息，选择jdk版本

再下一步，选择要使用的组件

完成项目创建。

项目目录如下

打开pom文件，

 新建一个测试路由

package com.hzau.securitydemo.controller;


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

/**
 * @ClassName TestController
 * @Description TODO
 * @Author yueyiming
 * @Date 2020/12/31 14:30
 * @Version 1.0
 * https://blog.csdn.net/hzau_itdog
 **/
@RestController
public class TestController {

    @RequestMapping("test")
    public  String test(){
        return "hello";
    }
}

 启动项目，日志如下

访问  http://127.0.0.1:8080/test

 需要登录。这里我们虽然没有配置SpringSecurity，但是默认运行了SpringSecurity，其默认使用用户user，密码打印在控制台

输入用户和密码

最常见的方式还是在配置文件里配置 

spring:
  security:
    user:
      name: user
      password: 123

重新启动登录，输入密码，正常访问。
