- 添加maven插件，让maven环境支持mybatis-generator组件
在pom.xml里面添加如下代码：
<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，添加数据库依赖
<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"?>
<!DOCTYPE generatorConfiguration PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN" "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">
<generatorConfiguration>
<!-- 数据库驱动包位置 -->
<classPathEntry
location="E:\apache-maven-3.3.9\repo\mysql\mysql-connector-java\5.1.18\mysql-connector-java-5.1.18.jar" />
<context id="Tables" targetRuntime="MyBatis3">
<commentGenerator>
<!-- 是否去除自动生成的注释 true：是 ： false:否 -->
<property name="suppressAllComments" value="true" />
</commentGenerator>
<!-- 数据库链接URL、用户名、密码 -->
<jdbcConnection driverClass="com.mysql.jdbc.Driver"
connectionURL="jdbc:mysql://192.168.100.52:3306/dev_test" userId="数据库用户名"
password="数据库密码">
<!--<jdbcConnection driverClass="oracle.jdbc.driver.OracleDriver" connectionURL="jdbc:oracle:thin:@localhost:1521:orcl"
userId="msa" password="msa"> -->
</jdbcConnection>
<javaTypeResolver>
<!-- 默认false，把JDBC DECIMAL 和 NUMERIC 类型解析为 Integer， 为 true时把JDBC DECIMAL和NUMERIC类型解析为java.math.BigDecimal -->
<property name="forceBigDecimals" value="true" />
</javaTypeResolver>
<!-- 生成实体类的包名和位置，这里配置将生成的实体类放在com.loan.test.entity这个包下 -->
<javaModelGenerator targetPackage="com.loan.test.entity"
targetProject=".\src\main\java\">
<!-- enableSubPackages:是否让schema作为包的后缀 -->
<property name="enableSubPackages" value="true" />
<!-- 从数据库返回的值被清理前后的空格 -->
<property name="trimStrings" value="true" />
</javaModelGenerator>
<!-- 生成的SQL映射文件包名和位置，这里配置将生成的SQL映射文件放在com.loan.test.dao.xml这个包下 -->
<sqlMapGenerator targetPackage="com.loan.test.dao.xml"
targetProject=".\src\main\java\">
<!-- enableSubPackages:是否让schema作为包的后缀 -->
<property name="enableSubPackages" value="true" />
</sqlMapGenerator>
<!-- 生成DAO的包名和位置，这里配置将生成的dao类放在com.loan.test.dao.mapper这个包下 -->
<javaClientGenerator type="XMLMAPPER"
targetPackage="com.loan.test.dao.mapper" targetProject=".\src\main\java\">
<!-- enableSubPackages:是否让schema作为包的后缀 -->
<property name="enableSubPackages" value="true" />
</javaClientGenerator>
<!-- 要生成那些表(更改tableName和domainObjectName就可以) -->
<table tableName="test" domainObjectName="Test"
enableCountByExample="false" enableUpdateByExample="false"
enableDeleteByExample="false" enableSelectByExample="false"
selectByExampleQueryId="false" />
</context>
</generatorConfiguration>
-
运用maven指令生成逆向工程
项目右键->run as->maven build...,Goals:中输入mybatis-generator:generate
如图 刷新项目。
