java去mybatis里面自动生成的Example文件 和烦人的注释

上篇mybatis里面写了怎么配置mybatis自动生成代码的生成器。
但是生成出来的代码含有Example文件和相当多的注释，令我很反感，所以根据我自己的需求和我想要得到的效果，于是我就编写了的代码来解决这2个烦人的东西 ：

import java.io.BufferedReader;
import java.io.File;
import java.io.FileReader;
import java.io.FileWriter;
import java.io.IOException;
import java.io.InputStream;
import java.util.Properties;
/**

public class DelAnnotation {
	private static String PROJECTPATH = null;
	private static String MODELPATH = null;
	private static String DAOPATH = null;
	private static String MAPPERPATH = null;
	/**
	 * 初始化路径
	 * @param pro
	 */
	public static void initPath(Properties pro){
		PROJECTPATH = pro.getProperty("projectpath");
		if(PROJECTPATH != null && !PROJECTPATH.equals("")){
			MODELPATH = PROJECTPATH + pro.getProperty("modelpath");
			DAOPATH = PROJECTPATH + pro.getProperty("daopath");
			MAPPERPATH = PROJECTPATH + pro.getProperty("mapperpath");
		}
		
	}

	public static void copyFile(File oldFile, File newFile, String className,
			int type) {
		BufferedReader reader = null;
		FileWriter fileWriter = null;
		try {
			reader = new BufferedReader(new FileReader(oldFile));
			fileWriter = new FileWriter(newFile);
			String tempString = null;
			int line = 1;
			boolean tag = true;
			boolean delimport = false;
			boolean examTag = false;
			String examStr = "";
			while ((tempString = reader.readLine()) != null) {
				if (type == 2) {
					if (tempString.contains("<!--")) {
						tag = false;
					}
					if(tempString.contains(className+"Mapper")){
						tempString = tempString.replace(className+"Mapper", className+"Dao");
					}
					if(tempString.contains("Example") && !examTag){
						examTag = true;
						examStr = tempString.substring(tempString.indexOf("<")+1,tempString.indexOf(" ", tempString.indexOf("<")));
					}
					
					if (tag && !examTag) {
						fileWriter.write(tempString + "\n");
					}
					if (tempString.contains("-->")) {

					}
					line++;
				} else {
					delimport = false;
					if (tempString.contains("/**")) {
						tag = false;
					}
					if (tag) {
						if (type == 1) {
							if (tempString.indexOf(className + "Mapper") != -1) {
								tempString = tempString.replaceAll(className
										+ "Mapper", className + "Dao");
							}
							if (tempString.indexOf(className + "Example") != -1) {
									delimport = true;
							}
							if(tempString.indexOf("record") != -1){
								tempString = tempString.replaceAll(
										"record",className.substring(0, 1).toLowerCase()
										+ className.substring(1,
												className.length()));
							}
							if (tempString.indexOf("example") != -1) {
								tempString = tempString.replaceAll(
										"example",className.substring(0, 1).toLowerCase()
										+ className.substring(1,
												className.length()));
							}
							if(!delimport){
								fileWriter.write(tempString + "\n");
							}
						}else{							
							fileWriter.write(tempString + "\n");
						}
					}
					if (tempString.contains("*/")) {
						tag = true;
					}
					line++;
				}

			}
			fileWriter.close();
			reader.close();
			oldFile.delete();
		} catch (IOException e) {
			System.out.println("文件删除失败："+e.getMessage());
		} finally {
			if (reader != null) {
				try {
					reader.close();
					fileWriter.close();
				} catch (IOException e1) {
					System.out.println("流关闭异常："+e1.getMessage());
				}
			}
		}
		
	}

	public static void main(String[] args) {
		InputStream in =new DelAnnotation().getClass().getClassLoader()
				.getResourceAsStream("config.properties"); 
		Properties pro = new Properties();
		try {

	}
}

config.properties配置文件

classname=TestMasterlog
projectpath=F:/myworkspace/TSSC
modelpath=/src/main/java/com/complaint/model/
daopath=/src/main/java/com/complaint/dao/
mapperpath=/src/main/resources/com/complaint/dao/mapping/

你也可以将上面的代码保存在和generator.bat（不知道generator.bat的童鞋可以看上一篇：http://jynine.iteye.com/blog/1879707）同一个路径下，
然后再generator.bat里面添加下面的代码：

javac DelAnnotation.java
java DelAnnotation

generator.bat最终效果如下：

@echo off
echo==========mybatis开始生成代码================
java -jar mybatis-generator-core-1.3.2.jar -configfile generator.xml -overwrite  
javac DelAnnotation.java
java DelAnnotation
pause
echo==========mybatis生成代码完毕================

ps:路径和上一篇有出入，请自行修改成你自己的路径。童鞋们也可以修改这个类，让它可以支持同时操作多个类。
