Reverse generation of DAO, Mapper.xml, Pojo (via maven) using the MyBatis generator plugin

directly into the topic, as the project was chosen using MAVEN to build, so chose to take advantage of the way Maven was built. (There is also a self-Baidu)

First, add the plugin in Pom.xml

            <plugin>                <groupId>Org.mybatis.generator</groupId>                <Artifactid>Mybatis-generator-maven-plugin</Artifactid>                <version>1.3.2</version>                <Configuration>                    <!--location of the configuration file -                    <ConfigurationFile>Src/main/resources/personal-generatorconfig.xml</ConfigurationFile>                    <verbose>True</verbose>                    <Overwrite>True</Overwrite>                </Configuration>              </plugin>

II. Configuration XML file

The XML file mainly uses the existing database tables, through the configuration, to make the database table information and Pojo, Mapper.xml, DAO produce contact

<?XML version= "1.0" encoding= "UTF-8"?>  <!DOCTYPE generatorconfiguration Public "-//mybatis.org//dtd mybatis Generator Configuration 1.0//en" "Http://myb Atis.apache.org/dtd/mybatis-generator-config_1_0.dtd ">  <generatorconfiguration>

Third, run generator plug-in

Operating method: In Eclipse, select the Pom.xml file, right-click the run As-->maven build...--> enter in the Goals box: Mybatis-generator:generate Run

In this way, the relevant files will be generated under the configured path, if necessary, can be self-deletion, renaming, very convenient
