Eclipse 中构建 Maven 项目的完整过程 - SpringBoot 项目

进行以下步骤的前提是你已经安装好本地maven库和eclipse中的maven插件了（有的eclipse中已经集成了maven插件）

一、Maven项目的新建

1、鼠标右键---->New----->Other...

2、直接点击下一步

3、默认的是maven-archetype-quickstart，不用修改，直接点击下一步

4、 Group Id 中输入项目的基本包名。

Artifact Id 中输入项目名。

Version 中的值默认就行，不进行选择。

Package 中写的是默认生成的一个包名，不写也可以。

　  接着点击完成就可以了。

5、创建好项目后结构如下：

这就是个普通的maven项目，也就是单机版项目。

二、Maven项目的配置

首先我们配一下项目的jdk，检查下项目的输出位置，Java Complier 不用管，因为接下来我们会在pom.xml 中配置使用maven的编译插件。

这里一般还需要新建两个资源目录，src/main/resources和src/test/resources，并且添加相应的输出路径。具体可参考我的另一篇博客----Eclipse中构建Maven项目的完整过程---普通Web项目.

接下来我们配置项目的pom.xml ，根据需要进行配置，我这里提供一个基础版的xml，只有一些最基本的配置，可以把服务跑起来，大家可以在这个基础上添加自己项目需要的配置

            </plugin>
        </plugins>
    </build>
</project>

配置完pom.xml 后对项目进行刷新，右键项目----->Maven----->Update Project...

接下来写及几个类，测试一下服务。

目录结构：

App.java

package com.sumavision.wangbo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

/**
 * SpringBoot 项目启动类
 *
 */
@SpringBootApplication
public class App
{
    public static void main( String[] args )
    {
        SpringApplication.run(App.class, args);
    }
}

UserController.java

package com.sumavision.wangbo.controller;

import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class UserController {

    @RequestMapping("/user/{name}")
    public String login(@PathVariable("name") String name){
        return name+"登陆成功！";
    }

    @RequestMapping("/xxx/{name}")
    public String loginout(@PathVariable("name") String name){
        return name+"退出成功！";
    }

}

三、项目运行

可以选择在eclipse中直接右键运行App.java 类中的main方法，直接就可以在浏览器中访问了。这种比较简单就不说了。

说一下打jar包的运行方式：

项目右键----->Run As------->Maven build...，接着在Goals后面写上打包命令，一般是先清除，再打包，所以写的是clean package，接着点击Run就可以了。

控制台显示的打包日志

显示打包成功，jar 包位于 H:\workspace\learn\wangbo\target\wangbo-0.0.1-SNAPSHOT.jar

接着可以直接在命令行中通过java -jar 命令启动该jar包，可以看到以下日志

由日志

　　Tomcat started on port(s): 8080 (http)
　　Started App in 3.426 seconds (JVM running for 3.924)

可以知道项目启动成功了。

四、项目访问

到此项目启动成功，可以在控制台Ctrl+C 结束项目运行

五、相关命令

Linux下启动应用：

springboot在linux下后台启动应用，首先cd到jar包所在目录，接着

java -jar sums-manage-0.0.1-SNAPSHOT.jar　　属于前台启动，Ctrl+C 会关闭应用

java -jar sums-manage-0.0.1-SNAPSHOT.jar &　　属于后台启动，Ctrl+C 不会关闭应用，但是关闭shell程序就会关闭应用

nohup java -jar sums-manage-0.0.1-SNAPSHOT.jar &　　属于后台启动，应用不会被其他操作打断

Linux下关闭应用：

ps -ef|grep sums-manage-0.0.1-SNAPSHOT.jar　　查看进程号

kill -9 xx　　强制终止进程

Linux下查看应用日志：

tail -f nohup.out　　查看线上日志，是通过nohup.out文件查看的

如果想查看日志记录文件，找到项目中配置的地方直接查看就行

一般maven用到的命令：

clean compile　　清除再编译

clean package　　清除再打包
