1 创建一个springBoot项目

　　导入 springSecurity 和 web 相关jar包

　　技巧：去除Tomcat相关jar包的依赖，因为我们的是springboot项目会自动继承Tomcat

　　　　

　　

2 在启动类上添加@RestController注解并在启动类中编写一些用于测试的方法

package cn.xiangxu.spring_security_system;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.security.access.prepost.PreAuthorize;
import org.springframework.security.config.annotation.method.configuration.EnableGlobalMethodSecurity;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

@SpringBootApplication
@RestController
//@EnableGlobalMethodSecurity(prePostEnabled = true) // 开启@PreAuthorize注解
public class SpringSecuritySystemApplication {

    public static void main(String[] args) {
        SpringApplication.run(SpringSecuritySystemApplication.class, args);
    }

    @GetMapping(value = "/")
    public String home() {
        return "Welcome to study springSecurity.";
    }

    @GetMapping(value = "/hello")
    public String hello() {
        return "hello boy";
    }

//    @PreAuthorize("hasRole('ROLE_ADMIN')") // 设定权限校验：只用ADMIN角色才能调用该接口
    @GetMapping("/roleAuth")
    public String role() {
        return "admin role";
    }
}

3 启动项目后访问在启动类中写好的接口

　　技巧01：如果导入了springSecurity相关的jar包后，springboot项目就会进行自动配置；因为启动类上的@SpringBootApplication注解包含了自动配置注解，所以我们启动项目后就默认开启了权限验证，在控制台上会打印出随记产生的密码，默认的登录名时user

　　

　　技巧02：在访问接口时会自动弹出一个登录窗口，登录名是user，密码就是控制台打印出的密码

　　

　　技巧03：如果输入用户名和密码后成功访问到响应的接口，而且再次访问其他的接口时不需要重新进行登录就表明SpringSecurity环境搭建完毕
