- 添加maven插件哀卫，讓maven環(huán)境支持mybatis-generator組件
在pom.xml里面添加如下代碼：
<build>
<finalName>taotao</finalName>
<pluginManagement>
<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>
<goal>generate</goal>
</goals>
</execution>
</executions>
<dependencies>
<dependency>
<groupId>org.mybatis.generator</groupId>
<artifactId>mybatis-generator-core</artifactId>
<version>1.3.2</version>
</dependency>
</dependencies>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.19.1</version>
<configuration>
<skipTests>true</skipTests>
</configuration>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-resources-plugin</artifactId>
<version>3.0.1</version>
<configuration>
<encoding>UTF-8</encoding>
</configuration>
</plugin>
</plugins>
</pluginManagement>
</build>
- 在pom.xml，添加數(shù)據(jù)庫(kù)依賴
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.1.35</version>
<scope>runtime</scope>
</dependency>
- 新建generator.xml配置文件
<?xml version="1.0" encoding="UTF-8"?>

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

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

<!-- 要生成那些表(更改tableName和domainObjectName就可以) -->
<table tableName="test" domainObjectName="Test"
enableCountByExample="false" enableUpdateByExample="false"

selectByExampleQueryId="false" />
</context>

運(yùn)用maven指令生成逆向工程
項(xiàng)目右鍵->run as->maven build...,Goals:中輸入mybatis-generator:generate
如圖 刷新項(xiàng)目。
