maven版的mybatis-generator使用步骤

1.新建maven项目mybatis-generator

2.在pom.xml里面添加配置

<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/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion>
<groupId>com.xdl</groupId>
<artifactId>Maven_project</artifactId>
<version>0.0.1-SNAPSHOT</version>

<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
</properties>

<dependencies>
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.1.35</version>
</dependency>
<dependency>
<groupId>org.mybatis.generator</groupId>
<artifactId>mybatis-generator-core</artifactId>
<version>1.3.2</version>
</dependency>
</dependencies>
<build>
<pluginManagement>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>1.7</source>
<target>1.7</target>
</configuration>
<version>3.3</version>
</plugin>
<plugin>
<groupId>org.mybatis.generator</groupId>
<artifactId>mybatis-generator-maven-plugin</artifactId>
<version>1.3.2</version>
<dependencies>
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.1.35</version>
</dependency>
</dependencies>
<configuration>
<!--配置文件的路径-->
<configurationFile>src/main/resources/generatorConfig.xml</configurationFile>
<overwrite>true</overwrite>
</configuration>
</plugin>
</plugins>
</pluginManagement>
</build>
</project>

3.在src/main/resources下面建立generatorConfig.xml文件，此处注意要在上面pom.xml中指定xml文件的路径

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE generatorConfiguration
PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"
"http://mybatis.org/dtd/mybatis-g
4000
enerator-config_1_0.dtd">

<generatorConfiguration>
<context id="testTables" targetRuntime="MyBatis3">
<commentGenerator>
<!-- 是否去除自动生成的注释 true：是 ： false:否 -->
<property name="suppressAllComments" value="true"/>
</commentGenerator>
<!--mysql数据库连接的信息：驱动类、连接地址、用户名、密码 -->
<jdbcConnection driverClass="com.mysql.jdbc.Driver"
connectionURL="jdbc:mysql://localhost:3306/train" userId="用户名"
password="密码">
</jdbcConnection>

<!-- 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 -->
<javaTypeResolver>
<property name="forceBigDecimals" value="false"/>
</javaTypeResolver>

<!-- targetProject:生成model类的位置，重要！！ -->
<javaModelGenerator targetPackage="com.demo.model" targetProject=".\src">
<!-- enableSubPackages:是否让schema作为包的后缀 -->
<property name="enableSubPackages" value="false"/>
<!-- 从数据库返回的值被清理前后的空格 -->
<property name="trimStrings" value="true"/>
</javaModelGenerator>

<!-- targetProject:mapper映射xml文件生成的位置，重要！！ -->
<sqlMapGenerator targetPackage="com.demo.mapper"
targetProject=".\src">
<property name="enableSubPackages" value="false"/>
</sqlMapGenerator>

<!-- targetPackage：mapper接口生成的位置，重要！！ -->
<javaClientGenerator type="XMLMAPPER"
targetPackage="com.demo.dao"
targetProject=".\src">
<property name="enableSubPackages" value="false"/>
</javaClientGenerator>

<!-- 指定数据库表，要生成哪些表，就写哪些表，要和数据库中对应，不能写错！ -->
<table tableName="train_info"></table>
<table tableName="train_manager"></table>
<table tableName="train_order"></table>
<table tableName="train_passenger"></table>
<table tableName="train_standby_ticket"></table>
<table tableName="train_station"></table>
<table tableName="train_station_relation"></table>
<table tableName="train_ticket"></table>
<table tableName="train_user"></table>
</context>
</generatorConfiguration>

4.执行mybatis-generator:generate命令，生成文件

1.项目右键，maven-->Update Project
2.项目右键，Run As-->3Maven Build-->在Goals中填入"mybatis-generator:generate"
3：点击Run，出现"Build Success"即可

5.刷新项目即可
