Maven 运行Spring Boot Application

Mon, 28 Jul 2025 17:48:38 +0800

1、创建pom.xml ，pom.xml内容如下

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>com.example</groupId>
<artifactId>myproject</artifactId>
<version>0.0.1-SNAPSHOT</version>
<parent>
 <groupId>org.springframework.boot</groupId>
 <artifactId>spring-boot-starter-parent</artifactId>
 <version>2.0.0.RELEASE</version>
</parent>
<!-- Additional lines to be added here... -->
</project>

执行命令

mvn depencency:tree

maven会自动安装默认的依赖文件

2、添加应用依赖

当开发一个具体类型的应用时需要添加具体的依赖，当我们开发一个WEB应用的时候，我们添加一个spring-boot-starter-web依赖，为了添加依赖我们在文件pom.xml文件的parent部分下面添加如下代码

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

添加后代码如下

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>com.example</groupId>
<artifactId>myproject</artifactId>
<version>0.0.1-SNAPSHOT</version>
<parent>
 <groupId>org.springframework.boot</groupId>
 <artifactId>spring-boot-starter-parent</artifactId>
 <version>2.0.0.RELEASE</version>
</parent>
<!-- Additional lines to be added here... -->
<dependencies>
 <dependency>
 <groupId>org.springframework.boot</groupId>
 <artifactId>spring-boot-starter-web</artifactId>
 </dependency>
</dependencies>
</project>

3、创建类文件

为了完成我们的应用，我们创建一个简单的Java文件，默认情况下，Maven从src/main/java编译源文件，因为我们创建一个src/main/java结构的目录，添加文件src/main/java/Example.java 代码内容如下

import org.springframework.boot.*;
import org.springframework.boot.autoconfigure.*;
import org.springframework.web.bind.annotation.*;
@RestController
@EnableAutoConfiguration
public class Example {
 @RequestMapping("/")
 String home() {
 return "Hello World!";
 }
 public static void main(String[] args) throws Exception {
 SpringApplication.run(Example.class, args);
 }
}

4、运行项目

mvn spring-boot:run

会得到如下输出

访问localhost:8080，你将看到输出如下内容

Hello World!

4、创建一个可执行的jar文件

为了创建可执行的jar文件,我们添加spring-boot-maven-plugin到我们的pom.xml文件

<build>
 <plugins>
 <plugin>
 <groupId>org.springframework.boot</groupId>
 <artifactId>spring-boot-maven-plugin</artifactId>
 </plugin>
 </plugins>
</build>

添加后文件内容如下

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>com.example</groupId>
<artifactId>myproject</artifactId>
<version>0.0.1-SNAPSHOT</version>
<parent>
 <groupId>org.springframework.boot</groupId>
 <artifactId>spring-boot-starter-parent</artifactId>
 <version>2.0.0.RELEASE</version>
</parent>
<!-- Additional lines to be added here... -->
<dependencies>
 <dependency>
 <groupId>org.springframework.boot</groupId>
 <artifactId>spring-boot-starter-web</artifactId>
 </dependency>
</dependencies>
<build>
 <plugins>
 <plugin>
 <groupId>org.springframework.boot</groupId>
 <artifactId>spring-boot-maven-plugin</artifactId>
 </plugin>
 </plugins>
</build>
</project>

然后执行如下命令

mvn package

执行完后查看target目录，可以看到myproject-0.0.1-SNAPSHOT.jar文件，

为了运行项目，执行如下命令

java -jar target/myproject-0.0.1-SNAPSHOT.jar

得到的结果跟第4步一样的输出
