Myeclipse配置Mybatis_generator生成mapper,model,client

在使用mybatis对接数据的时候，手动写mapper,model,client会比较费时间，可以试用mybatis_gererator来生成难度比较大的mybatis配置文件．
先要用myeclipse创建java工程．

将mysql-connector-java-5.1.18.jar放到指定的目录项目，并且配置generatorConfig.xml．

<?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="/opt/app-w/gitresp/testcore/src/main/webapp/WEB-INF/lib/mysql-connector-java-5.1.18.jar" />
    <context id="context1">
        <jdbcConnection driverClass="com.mysql.jdbc.Driver"
            connectionURL="jdbc:mysql://ip:3306/xx?useUnicode=true&amp;characterEncoding=UTF-8"
            userId="root" password="123456" />
        <javaModelGenerator targetPackage="model"
            targetProject="testcore" />
        <sqlMapGenerator targetPackage="mapper" targetProject="testcore" />
        <!--    数据库　表名　生成名 -->
        <javaClientGenerator targetPackage="client"
            targetProject="testcore" type="XMLMAPPER" />
        <table schema="ｘｘ" tableName="ｘｘ"
            domainObjectName="ｘｘ">
        </table>
    </context>
</generatorConfiguration>

然后到github上下载mybatis/generator插件，git　clone https://github.com/mybatis/generator.git.并且把目录generator/eclipse/UpdateSite下面的features和plugins拷贝到myeclipse相应的目录下面.
这样就可以右击在myeclipse中的generatorConfig.xml,找到生成mybatis artifacts选项,就可以生成mapper,model,client,如下图:

如果出现错误:Unexpected error while running MyBatis Generator. Exception getting JDBC Driver
这个就说明是<classPathEntry
location="/opt/app-w/gitresp/testcore/src/main/webapp/WEB-INF/lib/mysql-connector-java-5.1.18.jar" />
这里路径有问题,配置好就可以解决!
