网上找了一大堆的例子，感觉这个比较全，比较细，就是写的比较多，如果想看详细的，请看下面的链接，自动忽略我的：

本篇只写手头只有一个eclipse的情况下（maven插件已经装好了），怎么修改dao的类名

1.建maven项目：

1）![Center][]

2）![Center 1][]

3）![Center 2][]

4）![Center 3][]

5）如果没有src/main/java src/main/resources这样的结构，那么项目右键-》properties->java build path.选择libraries选项卡，edit,弹出编辑对话框，选择workspace default jre，确定后刷新就出来了。

2.修改pom.xml

自动生成的pom.xml如图

![Center 4][]

在16、17行之间添加如下依赖：

<dependency>  
        <groupId>log4j</groupId>  
        <artifactId>log4j</artifactId>  
        <version>1.2.17</version>  
    </dependency> 
    <dependency>
        <groupId>org.apache.ant</groupId>
        <artifactId>ant</artifactId>
        <version>1.7.1</version>
    </dependency>

保存。右键-》maven->update project一下，等源码拷进来就不会报错了

完整的如下：

<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>cn.xdf</groupId>
      <artifactId>Mybatis-Generator-Maven1</artifactId>
      <packaging>war</packaging>
      <version>0.0.1-SNAPSHOT</version>
      <name>Mybatis-Generator-Maven1 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>
        <dependency>  
            <groupId>log4j</groupId>  
            <artifactId>log4j</artifactId>  
            <version>1.2.17</version>  
        </dependency> 
        <dependency>
            <groupId>org.apache.ant</groupId>
            <artifactId>ant</artifactId>
            <version>1.7.1</version>
        </dependency>
      </dependencies>
      <build>
        <finalName>Mybatis-Generator-Maven1</finalName>
      </build>
    </project>

3.下载源码，项目右键-》maven->download sources。

![Center 5][]

这时会在本地库里找到这个源码：

![Center 6][]

把这个文件解压，把org所在的整个包拷贝到src/main/java下

![Center 7][]

将generatorConfig.xml、log4j.properties拷贝到src/main/resources下

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:\mysql-connector-java-5.1.9.jar" />
    	<context id="DB2Tables" targetRuntime="MyBatis3">
    		
    		<commentGenerator>
    			<property name="suppressDate" value="true" />
    			<property name="suppressAllComments" value="true" />
    		</commentGenerator>
    		<jdbcConnection driverClass="com.mysql.jdbc.Driver"
    			connectionURL="jdbc:mysql://127.0.0.1:3306/maventest" userId="root"
    			password="root">
    		</jdbcConnection>
    		
    		<javaModelGenerator targetPackage="cn.dulinan.domain"
    			targetProject="cn.dulinan.ssm">
    			<property name="enableSubPackages" value="true" />
    			<property name="trimStrings" value="true" />
    		</javaModelGenerator>
    		<sqlMapGenerator targetPackage="cn.dulinan.mapper"
    			targetProject="cn.dulinan.ssm">
    			<property name="enableSubPackages" value="true" />
    		</sqlMapGenerator>
    		<javaClientGenerator type="XMLMAPPER"
    			targetPackage="cn.dulinan.dao" targetProject="cn.dulinan.ssm">
    			<property name="enableSubPackages" value="true" />
    		</javaClientGenerator>
    		<table tableName="t_user" domainObjectName="User"></table>
    
    	</context>
    </generatorConfiguration>

上面的是把mysql-connector-java-5.1.9.jar直接放到D盘了，另外mysql连接的数据库，用户名，密码，及包名结构需要自己改一下

log4j.properties

#\u5B9A\u4E49LOG\u8F93\u51FA\u7EA7\u522B  
    log4j.rootLogger=DEBUG,Console,File
    #\u5B9A\u4E49\u65E5\u5FD7\u8F93\u51FA\u76EE\u7684\u5730\u4E3A\u63A7\u5236\u53F0  
    log4j.appender.Console=org.apache.log4j.ConsoleAppender
    log4j.appender.Console.Target=System.out
    #\u53EF\u4EE5\u7075\u6D3B\u5730\u6307\u5B9A\u65E5\u5FD7\u8F93\u51FA\u683C\u5F0F\uFF0C\u4E0B\u9762\u4E00\u884C\u662F\u6307\u5B9A\u5177\u4F53\u7684\u683C\u5F0F  
    log4j.appender.Console.layout = org.apache.log4j.PatternLayout
    log4j.appender.Console.layout.ConversionPattern=[%c] - %m%n
      
    #\u6587\u4EF6\u5927\u5C0F\u5230\u8FBE\u6307\u5B9A\u5C3A\u5BF8\u7684\u65F6\u5019\u4EA7\u751F\u4E00\u4E2A\u65B0\u7684\u6587\u4EF6  
    log4j.appender.File = org.apache.log4j.RollingFileAppender
    #\u6307\u5B9A\u8F93\u51FA\u76EE\u5F55  
    log4j.appender.File.File = logs/ssm.log
    #\u5B9A\u4E49\u6587\u4EF6\u6700\u5927\u5927\u5C0F  
    log4j.appender.File.MaxFileSize = 10MB
    # \u8F93\u51FA\u6240\u4EE5\u65E5\u5FD7\uFF0C\u5982\u679C\u6362\u6210DEBUG\u8868\u793A\u8F93\u51FADEBUG\u4EE5\u4E0A\u7EA7\u522B\u65E5\u5FD7  
    log4j.appender.File.Threshold = ALL
    log4j.appender.File.layout = org.apache.log4j.PatternLayout
    log4j.appender.File.layout.ConversionPattern =[%p] [%d{yyyy-MM-dd HH\:mm\:ss}][%c]%m%n
    
    log4j.logger.java.sql.ResultSet=INFO
    log4j.logger.org.apache=INFO
    log4j.logger.java.sql.Connection=DEBUG
    log4j.logger.java.sql.Statement=DEBUG
    log4j.logger.java.sql.PreparedStatement=DEBUG

4.修改文件

主要修改如下三个地方：

![Center 8][]![Center 9][]

1）IntrospectedTable.java中

第820行，将 sb.append("Mapper"); //$NON-NLS-1$   改成sb.append("Dao"); //修改Dao包名

![Center 10][]

2）添加GeneratorConfig.java文件，作为生成的入口

package org.mybatis.generator;
    
    import java.io.File;
    import java.util.ArrayList;
    import java.util.List;
    
    import org.mybatis.generator.api.MyBatisGenerator;
    import org.mybatis.generator.config.Configuration;
    import org.mybatis.generator.config.xml.ConfigurationParser;
    import org.mybatis.generator.internal.DefaultShellCallback;
    
    
    public class GeneratorConfig {
    
    	public static void main(String[] args) throws Exception{
    	       List<String> warnings = new ArrayList<String>();
    	       boolean overwrite = true;
    	       File configFile = new File(GeneratorConfig.class.getResource("/generatorConfig.xml").toURI());
    	       ConfigurationParser cp = new ConfigurationParser(warnings);
    	       Configuration config = cp.parseConfiguration(configFile);
    	       DefaultShellCallback callback = new DefaultShellCallback(overwrite);
    	       MyBatisGenerator myBatisGenerator = new MyBatisGenerator(config, callback, warnings);
    	       myBatisGenerator.generate(null);
    	}
    }

3）DefaultShellCallback.java，由于运行时，如果找不到xml配置的包名，在此类中会抛出异常，因此在这里，修改一下，直接创建文件

在这个类中第50行处，注释掉1，添加2

![Center 11][]

此时已修改完毕，在GeneratorConfig.java的main函数运行后，刷新项目，会有如下代码生成

![Center 12][]

包名已改好
