最近由于公司要求開發一個小小的插件，用來改變文件名字
簡單的說，就是讀取一個csv文件，里面只有兩列
如：test.csv
"OldName","NewName"
"test1.eps","1.eps"
"test2.eps","2.eps"
"test3.tif","3.eps"
然后用戶通過界面選擇csv文件，選擇源文件目錄，選擇目的文件目錄，選好再按一個鍵對原來文件按新的文件名輸出。
我開始拿到蒙了，因為自己沒有搞過呀，經過查資料，自己研究，搞定。
下面開始我們的實戰吧。
工欲善其事，必須利其器
首選搭建好開發環境。
1.安裝MyEclipse 6.0
2.安裝打包工具
net.sf.fjep.fatjar_0.0.27.zip
我是解壓到 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.重啟myeclipse
我們的開發環境就搞定啦
重啟后Window->Preferences可以看到 Fat Jar Preferences
說明你安裝成功
下面開始我們的項目
1.新建Plug-in Project名字自己取Demo
建好后可以看到結構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.編輯NewRenamer.java

5.編輯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.編輯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.上面我們把一切都編好了
然后選擇項目->右健->Fat jar->選擇main class [NewRenamer] ->finish就生成夾包了
8.編輯批處理文件
run.bat 里面加
start javaw -jar Demo_fat.jar
即可運行啦
說明:
jdk 1.42
這是本項目必須的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
