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)
2)
3)
4)
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
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。
这时会在本地库里找到这个源码:
把这个文件解压,把org所在的整个包拷贝到src/main/java下
将generatorConfig.xml、log4j.properties拷贝到src/main/resources下
generatorConfig.xml
<?xml version="1.0" encoding="UTF-8"?>

<!-- <table tableName="user" domainObjectName="User"

</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

4.修改文件
主要修改如下三个地方:
1)IntrospectedTable.java中
第820行,将 sb.append("Mapper"); //$NON-NLS-1$ 改成sb.append("Dao"); //修改Dao包名
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
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
包名已改好
