Question

Java中如何设置读取ini配置文件？

Answer 1

// 读取一般的属性文件
FileInputStream fin=new FileInputStream("my.ini"); // 打开文件
Properties props=new Properties();                 // 建立属性类
props.load(fin);                                   // 读入文件
fin.close();                                       // 关闭文件

Answer 2

/*
* IniReader.java
* 用Java读取INI文件(带section的)
* 示例：
* IniReader reader = new 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

这么专业的问题可以去专业的IT论坛查问一下.

Answer 4

直接手动修改不简单么？

Answer 5

使用IO流可以读取任何文件...
