有点简单,但也是原创哦。。亲测有效,期待指正。
更改了log多行的问题。。
例如//Log
Util;
一、注释log
import java.io.BufferedReader;
import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.FileReader;
import java.io.IOException;
public class CommentLog {
public static String dirpath = "/home/google/com";
// public static String dirpath = "/home/java";
public static String filepath = "/home/java/test1";
public static String newStr = "LogUtil.";
public static String oldStr = "//LogUtil.";
public static boolean judge = false;
public static String str = null;
public static boolean MyPanduan(String str) {
String strTest = str.trim();
if(!strTest.endsWith(";")) {
judge = true;
} else {
judge = false;
}
return judge;
}
public static void writeStrtoFile(StringBuffer sb1, String path) {
try {
String sb = "" + sb1;
FileOutputStream fos = new FileOutputStream(path, false);// true原有续写,false是追加。如果源文件不存在就新建了
fos.write(sb.getBytes());
fos.close();
} catch (Exception e) {
e.printStackTrace();
}
}
public static void replaceDir(String Mdirpath) {
File file = new File(Mdirpath);
if (file.isDirectory()) {
File[] tempList = file.listFiles();
for (File fi : tempList) {
if (fi.isFile()) {
if (!fi.getAbsoluteFile().equals("LogUtil.java")) {
replaceFile(fi.getAbsolutePath());
}
judge = false;
} else {
replaceDir(fi.getAbsolutePath());
}
}
}
}
public static void replaceFile(String path) {
try {
// read file content from file
StringBuffer sb = new StringBuffer("");
FileReader reader = new FileReader(path);
BufferedReader br = new BufferedReader(reader);
while ((str = br.readLine()) != null) {
if (str.contains(newStr)) {
str = str.replaceAll(newStr, oldStr);
MyPanduan(str);
sb.append(str);
} else {
if (judge == true) {
str = "//".concat(str);
MyPanduan(str);
}
sb.append(str);
}
sb.append("\n");
}
br.close();
reader.close();
if (sb != null) {
writeStrtoFile(sb, path);
}
}
catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
public static void main(String[] args) {
replaceDir(dirpath);
}
}
二、取消注释
