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
<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.sumavision.sums</groupId> <artifactId>wangbo</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>jar</packaging> <name>wangbo</name> <url>http://maven.apache.org</url> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <java.version>1.8</java.version> <mybatis.spring.boot.version>1.2.0</mybatis.spring.boot.version> </properties> <parent> <!-- 从springboot中继承默认值 --> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>1.5.6.RELEASE</version> </parent> <dependencies> <!-- 为web应用程序添加典型的依赖项 --> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <!-- springboot测试 --> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> <!-- mysql连接 --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> </dependency> <!-- mybatis --> <dependency> <groupId>org.mybatis.spring.boot</groupId> <artifactId>mybatis-spring-boot-starter</artifactId> <version>${mybatis.spring.boot.version}</version> </dependency> <!-- redis --> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-data-redis</artifactId> </dependency> <!-- 缓存 --> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-cache</artifactId> </dependency> </dependencies> <build> <plugins> <!-- maven编译打包插件 --> <plugin> <artifactId>maven-compiler-plugin</artifactId> <configuration> <source>${java.version}</source> <target>${java.version}</target> <encoding>${project.build.sourceEncoding}</encoding> </configuration> </plugin> <!-- springboot编译，生成可执行jar包插件 --> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </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:workspacelearnwangbo argetwangbo-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
