详细教程

创建Maven工程

修改pom.xml文件

添加父节点

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>3.5.3</version>
    </parent>

添加springboot依赖

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

添加镜像

    <!-- 配置阿里云仓库 -->
    <repositories>
        <repository>
            <id>aliyun-repos</id>
            <url>https://maven.aliyun.com/repository/public</url>
            <releases>
                <enabled>true</enabled>
            </releases>
            <snapshots>
                <enabled>false</enabled>
            </snapshots>
        </repository>
    </repositories>
    <pluginRepositories>
        <pluginRepository>
            <id>aliyun-repos</id>
            <url>https://maven.aliyun.com/repository/public</url>
            <releases>
                <enabled>true</enabled>
            </releases>
            <snapshots>
                <enabled>false</enabled>
            </snapshots>
        </pluginRepository>
    </pluginRepositories>

刷新

修改启动类

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

添加资源文件

添加配置文件

application.properties

添加简单示例

package com.zwh.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 World~~~~~~~";
    }
}

使用的java24需要消除警告

--enable-native-access=ALL-UNNAMED
 
--add-opens java.base/java.lang=ALL-UNNAMED

运行

查看端口

 查看结果

http://127.0.0.1:8080/hello
