Eclipse uses the Maven generator plugin to automatically generate the required code for MyBatis

One, the Maven pom.xml file introduces the plugin plugin

<plugins>

<plugin>
<groupId>org.mybatis.generator</groupId>
<artifactId>mybatis-generator-maven-plugin</artifactId>
<version>1.3.5</version>
<configuration>
<!--mybatis-generator Profile storage Address--
<configurationFile>src/test/resources/generator/mybatis-generator.xml</configurationFile>
<overwrite>true</overwrite>
</configuration>
<dependencies>
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.1.26</version>
</dependency>
</dependencies>
</plugin>

<plugins>

Second, create the Mybatis-generator.xml configuration file

Note: The Mybatis-generator.xml file creation location matches the configuration file specified in the plugin plugin in the Pom.xml file

Create a Mybatis-generator.xml file

<?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 ">

<property name= "Suppressdate" value= "true"/>
</commentGenerator>

</javaModelGenerator>

</javaClientGenerator>

</table>
-
<!--

<property name= "Useactualcolumnnames" value= "true"/>
<property name= "mergeable" value= "true"/>
</table>
-

</context>
</generatorConfiguration>

Note: Please see the mybatis-generator open source document or Google search for specific configuration tab content

third, generate code

(1) If it is in Eclipse, select the project or the Pom.xml file,

Click the right mouse button first select Run As-->maven build...-->

In the Goals box, type: mybatis-generator:generate

(2) If you enter the MAVEN command at the command line

Note: This command must be running under the current project directory:

MVN mybatis-generator:generate

Note: If using generator has been generated once code, then the next time you modify the database table structure, generate the corresponding table again, be sure to delete the original ***mapper.xml file and other corresponding files, otherwise in * * * Multiple code will be generated in the Mapper.xml file and will be an error during operation.

After the code is generated, the merit is farewell.
