Spring Security从入门到精通：入门案例准备工作&入门案例引入Spring Secuirity

入门案例准备工作

我们先要搭建一个简单的SpringBoot工程

设置父工程 添加依赖

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.5.0</version>
    </parent>
    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
            <optional>true</optional>
        </dependency>
    </dependencies>

创建启动类

@SpringBootApplication
public class SecurityApplication {

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

创建Controller

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

@RestController
public class HelloController {

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

入门案例引入Spring Secuirity

引入SpringSecurity

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

​ 引入依赖后我们在尝试去访问之前的接口就会自动跳转到一个SpringSecurity的默认登陆页面，默认用户名是user,密码会输出在控制台。

​ 必须登陆之后才能对接口进行访问。
