实例1：实现自定义Ant任务
其中FileSorter文件的源码如下：
package com.ant.test02; import java.io.BufferedReader; import java.io.BufferedWriter; import java.io.File; import java.io.FileReader; import java.io.FileWriter; import java.util.ArrayList; import java.util.Collections; import java.util.List; import java.util.ListIterator; import org.apache.tools.ant.BuildException; import org.apache.tools.ant.Task; public class FileSorter extends Task { private File srcFile; private File destFile; public File getSrcFile() { return srcFile; } public void setSrcFile(File srcFile) { this.srcFile = srcFile; } public File getDestFile() { return destFile; } public void setDestFile(File destFile) { this.destFile = destFile; } @Override public void execute() throws BuildException { try { BufferedReader fromFile = new BufferedReader( new FileReader(srcFile)); BufferedWriter toFile = new BufferedWriter(new FileWriter(destFile)); List<String> list = new ArrayList<String>(); String line = fromFile.readLine(); while (line != null) { list.add(line); line = fromFile.readLine(); } Collections.sort(list); for (ListIterator<String> li = list.listIterator(); li.hasNext();) { String str = li.next(); toFile.write(str); toFile.newLine(); } fromFile.close(); toFile.close(); } catch (Exception ex) { ex.printStackTrace(); } } } |
