mybatis-generator在myeclipse中的使用

1. 添加依赖

---

  2个需要的jar包，包括mybatis-generator-core和mysql-connector-java，一个插件mybatis-generator-maven-plugin。
pom.xml

<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.xx</groupId>  <artifactId>mybatis_generator</artifactId>  <version>0.0.1-SNAPSHOT</version>  <packaging>jar</packaging>  <name>mybatis_generator</name>  <url>http://maven.apache.org</url>  <properties>    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>    <mybatis-generator.version>1.3.2</mybatis-generator.version>  </properties>  <dependencies>    <!-- mysql数据库连接jar包 -->    <dependency>        <groupId>mysql</groupId>        <artifactId>mysql-connector-java</artifactId>        <version>5.1.38</version>    </dependency>    <!-- mysql-generator的jar包 -->    <dependency>            <groupId>org.mybatis.generator</groupId>            <artifactId>mybatis-generator-core</artifactId>            <version>${mybatis-generator.version}</version>    </dependency>    <!-- mysql-generator的plugin插件 -->    <dependency>          <groupId>org.mybatis.generator</groupId>          <artifactId>mybatis-generator-maven-plugin</artifactId>          <version>1.3.2</version>      </dependency>    </dependencies><!-- 不使用插件的原因是插件不太好用，plugin生成不了 --><!--   <build>    <plugins>        <plugin>                <groupId>org.mybatis.generator</groupId>                <artifactId>mybatis-generator-maven-plugin</artifactId>                <version>1.3.2</version>                 <configuration>                    <verbose>true</verbose>                    <overwrite>true</overwrite>                </configuration>        </plugin>    </plugins>  </build> --></project>

2. generatorConfig.xml配置

---

  新建maven工程，在src/main/resources中添加generatorConfig.xml文件，是mybatis-generator默认的地址
generatorConfig.xml

<?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>    <classPathEntry        location="D:\maven\mvnRespo\mysql\mysql-connector-java\5.1.38\mysql-connector-java-5.1.38.jar" />    <context id="mysqlTables" targetRuntime="MyBatis3">        <commentGenerator>            <property name="suppressAllComments" value="true" />        </commentGenerator>        <jdbcConnection driverClass="com.mysql.jdbc.Driver"            connectionURL="jdbc:mysql://localhost:3306/two"            userId="root" password="123456">        </jdbcConnection>        <javaTypeResolver>            <property name="forceBigDecimals" value="false" />        </javaTypeResolver>         <!-- 生成model模型，对应的包，存放位置可以指定具体的路径,如/ProjectName/src，也可以使用MAVEN来自动生成 -->        <javaModelGenerator targetPackage="com.two.entity"            targetProject="src/main/java">            <property name="enableSubPackages" value="true" />            <property name="trimStrings" value="true" />        </javaModelGenerator>         <!--对应的xml mapper文件  -->        <sqlMapGenerator targetPackage="mybatis" targetProject="src/main/resources">            <property name="enableSubPackages" value="true" />        </sqlMapGenerator>        <!-- 对应的dao接口 -->        <javaClientGenerator type="XMLMAPPER"            targetPackage="com.two.dao" targetProject="src/main/java">            <property name="enableSubPackages" value="true" />        </javaClientGenerator>         <!-- 这里是数据库的表名table_user 以及 POJO类的名字User -->        <table tableName="table_user" domainObjectName="User"            enableCountByExample="false" enableSelectByExample="false"            enableUpdateByExample="false" enableDeleteByExample="false">        </table>    </context></generatorConfiguration>

3. 数据库建表语句

---

新建two数据库,并添加table_user表

create database two;create table table_user(    username varchar(20) not null,    password varchar(20) not null,    birthday Date,    content varchar(100))

4. maven build

---

点击run as -> maven build -> 在goals里mybatis-generator:generate点击 run

最后在maven工程右键refresh就可以看到生成的对应文件了
