4. 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

5. 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";
    }
}

6. 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

1. 启动 SecurityApplication
2. 查看日志 5826 端口启动成功
   
3. 打开浏览器访问请求接口/hello，可成功访问到请求，如下：
