Maven project, using MyBatis, automatically generate Pojo entity classes, DAO, mapper based on the database

First, create a MAVEN project with Eclipse.

Second, under the Pom.xml file, add the following plug-in configuration:

<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" > <modelversion>4.0.0</  Modelversion> <groupId>com.liyi.test</groupId> <artifactId>hello-mybatis</artifactId> <packaging>war</packaging> <version>0.0.1-SNAPSHOT</version> <name>hello-mybatis Maven webapp</name> <url>http://maven.apache.org</url><dependencies> <dependency> <groupId>junit</groupId> <artifactid>junit</arti factid> <version>3.8.1</version> <scope>test</scope> </dependency> &LT;/DEP endencies> <build> <finalName>hello-mybatis</finalName> <pluginManagement> & Lt;plugins> <plugin> <groupId>org.mybatis.generator</groupId> <            Artifactid>mybatis-generator-maven-plugin</artifactid> <version>1.3.2</version>                <configuration> <configurationFile>src/main/resources/generator.xml</configurationFile> <verbose>true</verbose> <overwrite>true</overwrite> </configuration> <executions> <execution> <id>generate MyBatis artifacts</id> <goals> &lt ;goal>generate</goal> </goals> </execution> </execut Ions> <dependencies> <dependency> <groupid>org.mybatis.                    Generator</groupid> <artifactId>mybatis-generator-core</artifactId> <version>1.3.2</version> </dependency> </dependencies> &lt ;/plugin> </plugins> </pluginManagement> </build></project>

Third, find the configurationfile tag from Pom.xml, and follow the path on the label (Src/main/resources/generator.xml) into the core configuration file of the following generated code, Generator.xml:
