关于Java property 文件，我的一些看法（2）

我设想的properties文件具有的元素以及对应的正则验证相关代码：

package com.all.about.config.prop;

import java.util.regex.Pattern;

public class PropertyRegex {
private
static String
PROP_KEY =
"([^\\.=#][^=#]*[^\\.=#])";
private
static String
PROP_VAL =
"([^#]+)";
private
static String
PROP_REGEX =
"\\s*"+PROP_KEY+"\\s*=\\s*"+PROP_VAL+"\\s*";
private
static String
SINGLE_COMMENT_REGEX =
"#.*";
private
static String
MULTI_COMMENT_REGEX_S =
"/\\*.*";
private
static String
MULTI_COMMENT_REGEX_E =
".*\\*/";
private
static String
NEW_SECTION =
"\\[[^\\[\\]]+\\s+(ns\\s*=\\s*"+PROP_KEY+")\\s*\\]";

public
static
boolean isProperty(String property) {
return Pattern.matches(PROP_REGEX,
property);
}

public
static
boolean isSingleLineComment(String comment) {

return Pattern.matches(SINGLE_COMMENT_REGEX,
comment);
}

public
static
boolean beginMultipleLineComment(String comment) {
return Pattern.matches(MULTI_COMMENT_REGEX_S,
comment);
}

public
static
boolean endMultipleLineComment(String comment) {
return Pattern.matches(MULTI_COMMENT_REGEX_E,
comment);
}

public
static
boolean isNewSection(String section) {
return Pattern.matches(NEW_SECTION,
section);
}
}
