解析properties文件

@Test
public void analysis() {
//输入流
InputStream is = null;
try {
is = new FileInputStream(“src\main\resources\spring\jkxlh.properties”);//添加你的properties文件路径
} catch (FileNotFoundException e) {
e.printStackTrace();
}
//创建Properties对象
Properties properties = new Properties();
try {
//加载文件
properties.load(is);
//获取所有的键
Enumeration keys = properties.keys();
while(keys.hasMoreElements()) {
//遍历键集合，得到key 和 value输出
String key = (String) keys.nextElement();
String value = properties.getProperty(key);
System.out.println(key + “:” + value);
is.close();
}
} catch (IOException e) {
e.printStackTrace();
}
}

需要引入的包名

import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.io.InputStream;
import java.util.Enumeration;
import java.util.Properties;

properties文件内容格式例子

aaaa:18
bbb:222

解决properties中文乱码

aaaa:18
bbb:222你

@Test
public void se() {
//输入流
InputStream is = null;
BufferedReader bf=null;
try {
is = new FileInputStream(“src\main\resources\spring\jkxlh.properties”);//添加你的properties文件路径
bf = new BufferedReader(new InputStreamReader(is, “UTF-8”));
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}
//创建Properties对象
Properties properties = new Properties();
try {
//加载文件
properties.load(bf);
//获取所有的键
Enumeration keys = properties.keys();
while(keys.hasMoreElements()) {
//遍历键集合，得到key 和 value输出
String key = (String) keys.nextElement();
String value = properties.getProperty(key);
System.out.println(key + “:” + value);
is.close();
}
} catch (IOException e) {
e.printStackTrace();
}
