java权限管理新增一个角色如何与菜单建立联系

第一篇先讲一下 菜单角色的操作 大概思路是这样：

1、前端传入 含有角色的编号和菜单编号的json串 你需要做map处理 以菜单编号为key value则是这个含有角色编号 和菜单编号的实体（实体可自定义为VO层 避免与数据库的实体类混乱）

2、获取这个角色编号在数据库已经存入的菜单编号集合实体类

3、根据对map的key值判断 包含就不需要操作 直接把map中的这个实体类删除掉 不做处理

4、不包含的则需要把数据库内的这个角色菜单 做物理删除 因为前端发来的数据 就是最终确认 勾选的菜单权限 （前端传入的是最后勾选的菜单 json 不管之前如何 最后只是勾选的json 也是最终这个角色所拥有的角色菜单）

5、如果最后这个map 还有值得话 就是这个角色需要新增得角色菜单 做添加处理

6、这个也是最需要注意得一点 逻辑修改和添加 必须在同一个事务处理内 必须同步 ！ 望注意

求个java角色扮演游戏代码

我只有这些源码，不知行不

1.创建文件夹

//import　 java.io.*;

File myFolderPath = new File(%%1);

try {

if (!myFolderPath.exists()) {

myFolderPath.mkdir();

}

}

catch (Exception e) {

System.out.println("新建目录操作出错");

e.printStackTrace();

}

2.创建文件

//import java.io.*;

File myFilePath = new File(%%1);

try {

if (!myFilePath.exists()) {

myFilePath.createNewFile();

}

FileWriter resultFile = new FileWriter(myFilePath);

PrintWriter myFile = new PrintWriter(resultFile);

myFile.println(%%2);

myFile.flush();

resultFile.close();

}

catch (Exception e) {

System.out.println("新建文件操作出错");

e.printStackTrace();

}

3.删除文件

//import java.io.*;

File myDelFile = new File(%%1);

try {

myDelFile.delete();

}

catch (Exception e) {

System.out.println("删除文件操作出错");

e.printStackTrace();

}

4.删除文件夹

/*

import java.io.*;

import java.util.*;

*/

LinkedList folderList = new LinkedListString();

folderList.add(%%1);

while (folderList.size() 0) {

File file = new File(folderList.poll());

File[] files = file.listFiles();

ArrayListFilefileList = new ArrayListFile();

for (int i = 0; i files.length; i ) {

if (files[i].isDirectory()) {

folderList.add(files[i].getPath());

} else {

fileList.add(files[i]);

}

}

for (File f : fileList) {

f.delete();

}

}

folderList = new LinkedListString();

folderList.add(%%1);

while (folderList.size() 0) {

File file = new File(folderList.getLast());

if (file.delete()) {

folderList.removeLast();

} else {

File[] files = file.listFiles();

for (int i = 0; i files.length; i ) {

folderList.add(files[i].getPath());

}

}

}

5.删除一个文件下夹所有的文件夹

/*

import java.io.*;

private static LinkedListString folderList=null;

*/

File delfile=new File(%%1);

File[] files=delfile.listFiles();

for(int i=0;ifiles.length;i ){

if(files[i].isDirectory()){

if(!files[i].delete()){

folderList = new LinkedListString();

folderList.add(files[i]);

while (folderList.size() 0) {

File file = new File(folderList.poll());

File[] files = file.listFiles();

ArrayListFilefileList = new ArrayListFile();

for (int i = 0; i files.length; i ) {

if (files[i].isDirectory()) {

folderList.add(files[i].getPath());

} else {

fileList.add(files[i]);

}

}

for (File f : fileList) {

f.delete();

}

}

folderList = new LinkedListString();

folderList.add(files[i]);

while (folderList.size() 0) {

File file = new File(folderList.getLast());

if (file.delete()) {

folderList.removeLast();

} else {

File[] files = file.listFiles();

for (int i = 0; i files.length; i ) {

folderList.add(files[i].getPath());

}

}

}

}

}

}

6.清空文件夹

//import java.io.*;

File delfilefolder=new File(%%1);

try {

if (!delfilefolder.exists() !delfilefolder.delete()){

LinkedList folderList = new LinkedListString();

folderList.add(delfilefolder);

while (folderList.size() 0) {

File file = new File(folderList.poll());

File[] files = file.listFiles();

ArrayListFilefileList = new ArrayListFile();

for (int i = 0; i files.length; i ) {

if (files[i].isDirectory()) {

folderList.add(files[i].getPath());

} else {

fileList.add(files[i]);

}

}

for (File f : fileList) {

f.delete();

}

}

folderList = new LinkedListString();

folderList.add(delfilefolder);

while (folderList.size() 0) {

File file = new File(folderList.getLast());

if (file.delete()) {

folderList.removeLast();

} else {

File[] files = file.listFiles();

for (int i = 0; i files.length; i ) {

folderList.add(files[i].getPath());

}

}

}

}

delfilefolder.mkdir();

}

catch (Exception e) {

System.out.println("清空目录操作出错");

e.printStackTrace();

}

7.读取文件

//import java.io.

在Java游戏中让一个人物走动的代码是什么？

代码主要为以下：

}
