spring security 之 初识 spring security

本文主要让大家对spring security 有一个最初步的认识。

项目为spring boot web 项目 版本为 2.2.7.RELEASE。项目依赖如下：

</project>

spring security 依赖：

<!-- spring security -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-security</artifactId>
</dependency>

测试controller类：

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

@RestController
@RequestMapping("/test")
public class TestController {
    @GetMapping
    public String test(){
        System.out.println("hello");
        return "hello";
    }
}

　　

启动项目访问 上述接口：

http://127.0.0.1:8081/test

项目会跳转到spring security默认的登录界面。

用户名默认为user，密码在项目的启动日志里，如下图：

输入用户名：user  密码：1f794d2a-115b-4700-9f5d-386292bb788d

返回上述接口的正常返回信息

至此 spring security 初识完成，spring security相关内容后续会持续更新。
