Question

java中 读取文件时想用相对路径，代码怎么写？

Answer 1

test
|
src
|
t090417
|
test.properties
Read.java

test.properties:
TEST=test

Read.java:
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.util.Properties;

public class Read {
public static String TEST ;
private static Properties loadPropertyFile() throws FileNotFoundException,IOException{
Properties properties = new Properties() ;
FileInputStream fs = new FileInputStream("src/t090417/test.properties");
properties.load(fs);
return properties ;
}
public static void loadProperty(){
try{
Properties properties = loadPropertyFile();
TEST = properties.getProperty("TEST");
System.out.println("read from properties: "+TEST);
}catch(Exception e){
e.printStackTrace();
}
}
public static void main(String[] args) {
loadProperty();
}
}

其中用的就是相对路径！
