2.导入相关依赖pom.xml

    <mybatis-generator.version>1.3.5</mybatis-generator.version>
<dependencies>
  <!-- mybatis generator -->
    <dependency>
      <groupId>org.mybatis.generator</groupId>
      <artifactId>mybatis-generator-core</artifactId>
      <version>${mybatis-generator.version}</version>
    </dependency>
</dependencies>
  <build>
    <finalName>com.lianwei</finalName>
    <pluginManagement><!-- lock down plugins versions to avoid using Maven defaults (may be moved to parent pom) -->
      <plugins>
        <!--MyBatis Generator-->
        <plugin>
          <groupId>org.mybatis.generator</groupId>
          <artifactId>mybatis-generator-maven-plugin</artifactId>
          <version>1.3.2</version>
        </plugin>
      </plugins>
    </pluginManagement>
  </build>
