Java读取含中文key的properties文件

package com.service; import java.io.BufferedInputStream; import java.io.FileInputStream; import java.io.FileNotFoundException; import java.io.IOException; import java.io.InputStream; import java.io.InputStreamReader; import java.lang.reflect.InvocationTargetException; import java.lang.reflect.Method; import java.util.Properties; import com.dao.UserInfo; public class InsertDataToSDP { public static void main(String[] args) throws FileNotFoundException, IOException, IllegalAccessException, IllegalArgumentException, InvocationTargetException, ReflectiveOperationException, RuntimeException { Properties pps = new Properties(); InputStream in = new BufferedInputStream(new FileInputStream("src/resources/properties/SDP_ExcelMapDb.properties")); //prop.load(in);//直接这么写，如果properties文件中有汉子，则汉字会乱码。因为未设置编码格式。 pps.load(new InputStreamReader(in, "utf-8")); String key = "用户名"; String columnName = pps.getProperty(key); String setMethodName = "set" + columnName.substring(0, 1).toUpperCase() + columnName.substring(1); //获取方法 UserInfo userInfo = new UserInfo(); Method setMethod = userInfo.getClass().getDeclaredMethod(setMethodName, String.class); //调用方法 setMethod.invoke(userInfo, "bbb"); //查看运行效果 System.out.println(userInfo.getUserName()); } }
