摘要: generator.xml 生成mybatis代码的核心配置文件

1、首先，用eclipse创建一个maven项目。

2、其次，在pom文件下，加入如下插件配置：

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/maven-v4_0_0.xsd">   <modelVersion>4.0.0</modelVersion>   <groupId>com.liyi.test</groupId>   <artifactId>hello-mybatis</artifactId>   <packaging>war</packaging>   <version>0.0.1-SNAPSHOT</version>   <name>hello-mybatis Maven Webapp</name>   <url>http://maven.apache.org</url>   <dependencies>     <dependency>       <groupId>junit</groupId>       <artifactId>junit</artifactId>       <version>3.8.1</version>       <scope>test</scope>     </dependency>   </dependencies>   <build>     <finalName>hello-mybatis</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/mybatis-generator/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>         </plugins>          </pluginManagement>      </build> </project>

3、从pom.xml中找到configurationFile标签，按照标签上的路径放入一下生成代码的核心配置文件，generator.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="C:\Users\Administrator\.m2\repository\mysql\mysql-connector-java\5.1.21\mysql-connector-java-5.1.21.jar" />             <context id="DB2Tables" targetRuntime="MyBatis3">          <commentGenerator>              <property name="suppressAllComments" value="true" />          </commentGenerator>                     <jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://localhost:3306/test" userId="root" password="1234">                     </jdbcConnection>          <javaTypeResolver>              <property name="forceBigDecimals" value="false" />          </javaTypeResolver>                    <javaModelGenerator targetPackage="com.liyi.test.domain" targetProject="M:\workspace\hello-mybatis\src\main\java\">                                                                                                <property name="enableSubPackages" value="true" />              <property name="trimStrings" value="true" />          </javaModelGenerator>                    <sqlMapGenerator targetPackage="com.liyi.test.mapping" targetProject="M:\workspace\hello-mybatis\src\main\java\">              <property name="enableSubPackages" value="true" />          </sqlMapGenerator>                    <javaClientGenerator type="XMLMAPPER" targetPackage="com.liyi.test.dao" targetProject="M:\workspace\hello-mybatis\src\main\java\">              <property name="enableSubPackages" value="true" />          </javaClientGenerator>                    <table tableName="tab_user" domainObjectName="User" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false" />      </context> </generatorConfiguration>

4、cmd打开dos窗口，到项目的根路径，比如我的

M：

cd workspace/hello-mybatis/

执行mvn mybatis-generator:generate(前提是你的电脑配置了maven的环境变量，可以用mvn命令)

刷新项目就有以下效果了。
