测试方法

//本地tomcat
//    private  String url = "http://127.0.0.1:8080/Car4s-1.0-SNAPSHOT/carApi/getCarAll";//获取全部数据
//    private  String url = "http://127.0.0.1:8080/Car4s-1.0-SNAPSHOT/carApi/getCar";//获取某一条记录
//    private String url = "http://127.0.0.1:8080/Car4s-1.0-SNAPSHOT/carApi/postCarList";//推送数据
