java 比properties好的文件读取方法

properties不支持中文，必须转码，让可读性很差。所以随便写了一个ini文件，规则还是一样，支持#注释，这个工具类把所有的配置都放到map里返回。

先看效果！

ini文件内容：

=====================================================

#不带[section]

aa=123

bB=我们

#带section

[abc]

cc=wejefdlfjdsk

Dd=kdjfsfl

=====================================================

运行结果：

=====================================================

{aa=123, bB=我们, abc.cc=wejefdlfjdsk, abc.Dd=kdjfsfl}

=====================================================

代码如下：

package menu;

import java.io.BufferedReader;
import java.io.FileReader;
import java.util.HashMap;
import java.util.Map;

				if (firstLeftSquareBrackets >= 0 && firstRightSquareBrackets >= 0
						&& firstLeftSquareBrackets < firstRightSquareBrackets) {
					Section = strLine.substring(firstLeftSquareBrackets + 1, firstRightSquareBrackets);
				} else {

						continue;

					} else {

					iniMap.put(hashKey, Value);
				}
