import org.apache.commons.lang.StringEscapeUtils;
public class StringEscapeUtils_Test {
     public static void main(String[] args) {
 //           String s = "\\u79fb\\u52a8\\u4e92\\u8054\\u7f51\\u5e94\\u7528";
            String s = "{\n" + "\t\"id\":2, \"name\":\"大虾\", \n" + "\t\"price\":12.3, \n"
                 + "\t\"imagePath\":\"http://192.168.10.165:8080/L05_Server/images/f1.jpg\"\n" + "}\n";
            String s2 = StringEscapeUtils.unescapeJava(s);
            System.out.println("s:"+s);
            System.out.println("s2:"+s2);
 
        }
 }
