最近由于公司要求开发一个小小的插件，用来改变文件名字
简单的说，就是读取一个csv文件，里面只有两列
如：test.csv
"OldName","NewName"
"test1.eps","1.eps"
"test2.eps","2.eps"
"test3.tif","3.eps"
然后用户通过界面选择csv文件，选择源文件目录，选择目的文件目录，选好再按一个键对原来文件按新的文件名输出。

我开始拿到蒙了，因为自己没有搞过呀，经过查资料，自己研究，搞定。
下面开始我们的实战吧。

工欲善其事，必须利其器

首选搭建好开发环境。

1.安装MyEclipse 6.0
2.安装打包工具
   net.sf.fjep.fatjar_0.0.27.zip
   我是解压到 MyEclipse 6.0\fjep\eclipse\plugins
    在MyEclipse 6.0\eclipse\links
 建fjep.link 里，添加 path=C:\\Program Files\\MyEclipse 6.0\\fjep
3.重启myeclipse
 我们的开发环境就搞定啦
 重启后Window->Preferences可以看到 Fat Jar Preferences
    说明你安装成功
 
下面开始我们的项目
1.新建Plug-in Project名字自己取Demo
  建好后可以看到结构Demo --src
                         --bin
2.新建log4j.properties
 log4j.rootLogger=DEBUG, stdout
 log4j.appender.stdout=org.apache.log4j.ConsoleAppender
 log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
 log4j.appender.stdout.layout.ConversionPattern=%c{1} - %m%n
 log4j.logger.java.sql.PreparedStatement=DEBUG
3.新建cvs.properties  
    csv.field.key=OldName, NewName
4.编辑NewRenamer.java

5.编辑BaseObject.java

import org.apache.commons.lang.builder.HashCodeBuilder;
import org.apache.commons.lang.builder.ToStringStyle;
import org.apache.commons.lang.builder.ToStringBuilder;
import org.apache.commons.lang.builder.EqualsBuilder;
import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;

import java.io.Serializable;

public class BaseObject implements Serializable {

    public static final Log log = LogFactory.getLog(BaseObject.class);

    public String toString() {
        return ToStringBuilder.reflectionToString(this, ToStringStyle.MULTI_LINE_STYLE);
    }

    public boolean equals(Object o) {
        return EqualsBuilder.reflectionEquals(this, o);
    }

    public int hashCode() {
        return HashCodeBuilder.reflectionHashCode(this);
    }

}
6.编辑TabItemData.java

public class TabItemData extends BaseObject{
 String sourceDir = "";
 String csvFile = "";
 String fileInSourceDir = "";
 String destinationDir = "";
 String fileInDestinationDir = "";
 
 
 public TabItemData(String csvFile,String sourceDir,
   String fileInSourceDir,
   String destinationDir,
   String fileInDestinationDir){
  this.csvFile = csvFile;
  this.sourceDir = sourceDir;
  this.fileInSourceDir = fileInSourceDir;
  this.destinationDir = destinationDir;
  this.fileInDestinationDir = fileInDestinationDir;
 
 }
 
 
 public String getCsvFile() {
  return csvFile;
 }

 public void setCsvFile(String csvFile) {
  this.csvFile = csvFile;
 }

 public String getSourceFilePath(){
  return this.getSourceDir() + this.getFileInSourceDir();
 }
 
 public String getDestinationFilePath(){
  return this.getDestinationDir() + this.getFileInDestinationDir();
 }
 
 public String getDestinationDir() {
  return destinationDir;
 }
 public void setDestinationDir(String destinationDir) {
  this.destinationDir = destinationDir;
 }
 public String getFileInDestinationDir() {
  return fileInDestinationDir;
 }
 public void setFileInDestinationDir(String fileInDestinationDir) {
  this.fileInDestinationDir = fileInDestinationDir;
 }
 public String getFileInSourceDir() {
  return fileInSourceDir;
 }
 public void setFileInSourceDir(String fileInSourceDir) {
  this.fileInSourceDir = fileInSourceDir;
 }
 public String getSourceDir() {
  return sourceDir;
 }
 public void setSourceDir(String sourceDir) {
  this.sourceDir = sourceDir;
 }
 
 

}

7.上面我们把一切都编好了
  然后选择项目->右健->Fat jar->选择main class [NewRenamer] ->finish就生成夹包了
8.编辑批处理文件 
run.bat 里面加
start javaw -jar Demo_fat.jar

即可运行啦

说明:
jdk 1.42
这是本项目必须的jar包
commons-collections-3.0.jar
commons-configuration-1.5.jar
commons-io-1.2.jar
commons-lang-2.4.jar
commons-logging.jar
csvjdbc.jar
log4j-1.2.9.jar
