1.修改pom.xml文件

<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>top.ytheng</groupId>
<artifactId>springboot-demo</artifactId>
<version>0.0.1</version>
<packaging>war</packaging> <parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.0.5.RELEASE</version>
<relativePath/> 
</parent> <properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>

<java.version>1.8</java.version>
</properties> <dependencies>
<dependency>

<optional>true</optional>
<scope>true</scope>
</dependency>
</dependencies> <build>
<finalName>myspringboot</finalName>
<plugins>
<plugin>

<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
<plugin>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>1.8</source>
<target>1.8</target>
</configuration>
</plugin>
</plugins>
</build>
</project>

2.添加控制器Controller

package top.ytheng.demo.controller;import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;@Controller
@RequestMapping("/file")
public class FileController { @RequestMapping("/testpath")
@ResponseBody
private Object testPath() {
return "Success";
}}

3.添加启动类

package top.ytheng.demo;import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;@SpringBootApplication
public class DemoApplication extends SpringBootServletInitializer { @Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(DemoApplication.class);
} public static void main(String[] args) throws Exception {
SpringApplication.run(DemoApplication.class, args);
}
}

4.右键项目依次执行Run As -> Maven Clean 和 Maven Install，会在target目录下生成war包
