SpringMVC构建REST接口:第二篇 配置Maven的pom.xml文件

Maven通过项目中的pom.xml文件，对项目引用的jar、测试、环境、构建生成等进行配置。

一、一个pom.xml文件通常包括三个部分：头部、依赖部、构建生成部。为了对pom.xml更好的操作，建议使用Eclipse 4.3以上版本。

1、头部

设置maven识别的项目信息，如groupId、artifactId、packaging、version、name、url、developers等，一些描述性的

2、依赖部

SpringMVC写REST接口，引用的包比较少，就以下几个部分:

 A、测试：junit

B、spring框架：spring-webmvc、spring-test。spring框架的其它包，在spring-webmvc都包含了，不用再引用。

C、mysql驱动 ：mysql-connector-java、mybatis-spring

 D、连接池：c3p0

E、json解析器：org.codehaus.jackson的jackson-core-asl、jackson-core-lgpl、jackson-mapper-asl、jackson-mapper-lgpl

 F、文件上传：commons-io、commons-fileupload

G、HTTP客户端：httpclient

 H、日志:log4j

I、环境:jstl、standard、javaee-api

3、构建生成部

设置项目的生成目标、资源以及Maven插件.

      二、完整的SpringMVC写REST的pom.xml

<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/maven-v4_0_0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>com.jiahe.rest</groupId>                    1、 修改为项目的groupId
<artifactId>demo2</artifactId>                               2、修改为项目的artifactId
<packaging>war</packaging>
<version>0.0.1-SNAPSHOT</version>                 3、修改为项目的版本
<name>demo2 Maven Webapp</name>            4、修改为项目的name
<url>http://maven.apache.org</url>
<developers>

</project>

综上，只需要修改5个地方，SpringMVC写REST的pom.xml就配置完整了。这里需要注意mybatis-spring的版本，它决定了spring框架的版本。
