使用maven搭建ssm框架

环境：Eclipse+Maven+jdk1.8+Tomcat8

刚开始用的myeclipse2014+tomcat6,7+jdk1.8然后中间出现了各种各样的问题，暴力全部卸载，重新装的。

一、安装maven

官网下载https://maven.apache.org/download.cgi

选择其中一个下载即可。

下载后将其解压到D:\develop\Java\apache-maven-3.5.3

设置环境变量PATH中加入%MAVEN_HOME%\bin，新建系统变量，变量名：MAVEN_HOME，变量值：D:\develop\Java\apache-maven-3.5.3

配置成功后使用命令mvn -v查看出现：

二、设置maven数据仓库：

maven的数据仓库默认位置为c:用户\lenovo\.m2\repository下，将默认的位置改为D:\develop\maven-repository\maven-jar,更改D:\develop\Java\apache-maven-3.5.3\conf下的setting.xml文件中的默认仓库配置：

<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">
  
  <localRepository>D:\develop\maven-repository\maven-jar</localRepository>

设置mirror标签

 <mirrors>
  	<mirror>
       <id>nexus-aliyun</id>
       <mirrorOf>*</mirrorOf>
       <name>Nexus aliyun</name>
       <url>http://maven.aliyun.com/nexus/content/groups/public</url>
    </mirror>

默认镜像的位置。

maven的默认jre为1.5,会出现很多问题，所以修改属性：

<profiles>
    <profile>

    <id>jdk-1.8</id>

    <activation>

        <activeByDefault>true</activeByDefault>

        <jdk>1.8</jdk>

    </activation>

    <properties>

        <maven.compiler.source>1.8</maven.compiler.source>

        <maven.compiler.target>1.8</maven.compiler.target>

        <maven.compiler.compilerVersion>1.8</maven.compiler.compilerVersion>

    </properties>

</profile>

完成后保存，并将setting文件复制一份放在D:\develop\maven-repository\maven-jar下面。

三、eclipse中集成maven

windows->preferences->maven->java->installed JREs

windows->preferences->maven->installtions->add

windows->preferences->maven->user settings

全局设置是使用maven中的setting,用户设置中使用的是repository中的setting文件。

四、eclipse中创建maven项目

五、整合搭建SSM（Spring+SpringMVC+Mybaits）

修改pom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/maven-v4_0_0.xsd">
