springsecurity入门案例

没有引用Spring Security依赖，是不会出现访问接口需要登录。只要引入了Spring Security依赖，Spring Boot就会对Spring Security做进行默认的权限管理配置，默认情况下，它要求所有的请求必须认证后才能访问

第一步：创建springboot项目

第二步：pom.xml

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">
	<modelVersion>4.0.0modelVersion>
	<parent>

		<artifactId>spring-boot-starter-parentartifactId>

project>

第三步：application.properties

默认为8080，可以不用设置

server.port=8081

第四步：创建controller

package com.springboot.controller;

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 HelloController {
	
	@GetMapping("/hello")
	public String hello() {
		return "hello spring security";
	}

}

第五步：启动springboot项目，浏览器访问

访问localhost:8081/test/hello回车后，他会变成如下图

默认用户名为：user，密码在启动控制台可以找到

输入用户名、密码便可以访问到
