2026-04-07 09:18:27 作者：君九@DBA

本文介绍了使用SpringBoot 3.2.4创建一个简单的安全验证项目的过程,包括引入依赖、配置文件修改、创建控制器和启动类等步骤,并最终成功启动项目并在浏览器访问到请求接口,感兴趣的朋友跟随小编一起看看吧

环境说明

JDK 版本：

C:\Users\JZADMIN>java -version
java version "21.0.10" 2026-01-20 LTS
Java(TM) SE Runtime Environment (build 21.0.10+8-LTS-217)
Java HotSpot(TM) 64-Bit Server VM (build 21.0.10+8-LTS-217, mixed mode, sharing)
C:\Users\JZADMIN>

MySQL 版本：8.4.7
SpringBoot 版本：3.2.4

创建项目

代码已推送至 Gitee 仓库：springdecurity-demo

项目创建完成后，结构如下：

File -->> New -->> Project

填写项目信息

修改 pom.xml 文件，引入后续需使用到依赖包。

修改 application.yml 配置文件

server:
  port: 5826
spring:
  application:
    name: security-demo
  datasource:
    type: com.alibaba.druid.pool.DruidDataSource
    driver-class-name: com.mysql.cj.jdbc.Driver
    url: jdbc:mysql://localhost:3306/security?useUnicode=true&characterEncoding=utf8&zeroDateTimeBehavior=convertToNull&useSSL=
    username: root
    password: 123456

新建 HelloController ,用于启动项目功能测试。

package com.junjiu.springboot3.controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
/**
 * program: security-demo
 * ClassName: HelloController
 * description:
 *
 * @author: 君九
 * @create: 2026-04-01 14:30
 * @version: 1.0
 **/
@RestController
public class HelloController {
    @RequestMapping("/hello")
    public String hello(){
        return "hello ~ 君九";
    }
}

创建启动类 SecurityApplication

package com.junjiu.springboot3;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;
/**
 * program: security-demo
 * ClassName: SecurityApplication
 * description:
 *
 * @author: 君九
 * @create: 2026-04-01 14:30
 * @version: 1.0
 **/
//@SpringBootApplication(exclude = {
//        DataSourceAutoConfiguration.class
//})
@SpringBootApplication
public class SecurityApplication {
    public static void main(String[] args) {
        SpringApplication.run(SecurityApplication.class, args);
    }
}

启动验证

启动 SecurityApplication

查看日志 5826 端口启动成功

打开浏览器访问请求接口/hello，可成功访问到请求，如下：
