java - Spring boot 改成war后部署到本地的tomcat上,无法访问项目

问题描述

问 题

1.我按照网上的教程将Spring boot项目改成war进行打包,然后部署在本机的tomcat7.0上,启动tomcat,访问项目时发现无法访问项目了.

2.pom文件的内容

<project xmlns="http://maven.apache.org/POM/4... http://maven.apache.org/xsd/maven-4.0.0.xsd">

    </plugins>
</build>

</project>

3.启动类配置

package com.ming.wei.yue;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.support.SpringBootServletInitializer;
@SpringBootApplication
public class ApplicationStart extends SpringBootServletInitializer{

public static void main(String[] args){
    SpringApplication.run(ApplicationStart.class, args);
}
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
    return builder.sources(ApplicationStart.class);
}

}

4.controller类

package com.ming.wei.yue.action;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class Bargain {

@RequestMapping(value="/test")
@ResponseBody
public String test(){
    return "ECS1";
}

}
5.配置文件的信息

6.eclipse上直接使用maven install命令打包

将这个war包放到本机的tomcat的webapps目录下面,并且改名成demo.war

7.启动Tomcat7

8.测试访问,访问报错

请教我这是哪里有问题啊?

解决方案

你的application.yml中配置的server.port配置的是spring boot内置的tomcat的端口号, 打成war包部署在独立的tomcat上之后, 你配置的server.port是不起作用的.
