Maven+mybatis教程

首先，配置maven

在eclipse中把maven路径和settings.xml文件配置好之后，否则后续会有一些问题 

可以设一个环境变量M2_HOME指向你的maven安装目录

M2_HOME=G:javaapache-maven-3.3.3

然后在Window->Preference->Java->Installed JREs->Edit

在Default VM arguments中设置

-Dmaven.multiModuleProjectDirectory=$M2_HOME

 

 新建mavenproject 直接默认下一步。

pom.xml文件如下：

<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">

除此之外还需要一个generatorConfig.xml用来配置mybatis generator:

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE generatorConfiguration

  PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"

  "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">

<generatorConfiguration>

<classPathEntry

location="D:javamybatismybatis-generator-core-1.3.2libmysql-connector-java-5.1.18-bin.jar" />

<context id="DB2Tables" targetRuntime="MyBatis3">

<commentGenerator>

<property name="suppressDate" value="true" />

<property name="suppressAllComments" value="true" />

</commentGenerator>

<jdbcConnection driverClass="com.mysql.jdbc.Driver"

connectionURL="jdbc:mysql://127.0.0.1/test" userId="root" password="123456">

</jdbcConnection>

<javaTypeResolver>

<property name="forceBigDecimals" value="false" />

</javaTypeResolver>

<javaModelGenerator targetPackage="test.upload.model"

targetProject="srcmainjava">

<property name="enableSubPackages" value="true" />

<property name="trimStrings" value="true" />

</javaModelGenerator>

<sqlMapGenerator targetPackage="test.upload.mapping"

targetProject="srcmainjava">

<property name="enableSubPackages" value="true" />

</sqlMapGenerator>

<javaClientGenerator type="XMLMAPPER"

targetPackage="test.upload.dao" targetProject="srcmainjava">

<property name="enableSubPackages" value="true" />

</javaClientGenerator>

<table tableName="user" domainObjectName="User"

enableCountByExample="true" enableUpdateByExample="true"

enableDeleteByExample="true" enableSelectByExample="true"

selectByExampleQueryId="true"></table>

</context>

</generatorConfiguration>

这个generatorConfig.xml可以放到srcmain esources目录中。如果没有这个文件夹，就新建一个。这样，这个资源文件会被mybatis generator找到并解析。

然后就用maven来产生代码。右键点你的项目，选择Run as->Run configurations，出来对话框如图：

 

 输入对了以后就点Run了。后面就是一些maven的log了，可以看到产生了很多代码。

 看到这些表示成功了
