用Java读取INI文件(带section的)

最终是通过Properties来实现的,比直接字符流来读取多了很多便利. 可以直接定位到域,根据键就能拿到值.而不是遍历判断来取值

/*

* IniReader.java

* 用Java读取INI文件(带section的)

* 示例：

* tmp.IniReader reader = new tmp.IniReader("E:\\james\\win.ini");

* out.println(reader.getValue("TestSect3", "kkk 6"));

*/

package tmp;

import java.io.BufferedReader;

import java.io.FileReader;

import java.io.IOException;

import java.util.HashMap;

import java.util.Properties;

public class IniReader {

protected HashMap sections = new HashMap();

private transient String currentSecion;

private transient Properties current;

public IniReader(String filename) throws IOException {

BufferedReader reader = new BufferedReader(new FileReader(filename));

read(reader);

reader.close();

}

protected void read(BufferedReader reader) throws IOException {

String line;

while ((line = reader.readLine()) != null) {

parseLine(line);

}

}

protected void parseLine(String line) {

line = line.trim();

if (line.matches("\\[.*\\]")) {

currentSecion = line.replaceFirst("\\[(.*)\\]", "$1");

current = new Properties();

sections.put(currentSecion, current);

} else if (line.matches(".*=.*")) {

if (current != null) {

int i = line.indexOf('=');

String name = line.substring(0, i);

String value = line.substring(i + 1);

current.setProperty(name, value);

}

}

}

public String getValue(String section, String name) {

Properties p = (Properties) sections.get(section);

if (p == null) {

return null;

}

String value = p.getProperty(name);

return value;

}

}

ini文件如下：

[TestSect1]

kkk 1=VVVVVVVVVVV1

kkk 2=VVVVVVVVVVV2

[TestSect2]

kkk 3=VVVVVVVVVVV3

kkk 4=VVVVVVVVVVV4

[TestSect3]

kkk 5=VVVVVVVVVVV5

kkk 6=VVVVVVVVVVV6
