@IRequest("testRequest")public interface ITestRequest { String testGet(@IRequestParam("location") String location, @IRequestParam("output") String output, @IRequestParam("ak") String ak); BaiduWeatherEntity testGetEntity(@IRequestParam("location") String location, @IRequestParam("output") String output, @IRequestParam("ak") String ak);}
请求百度的天气情况,一个是直接返回字符串,一个是返回对象
测试用例public class ITestRequestTest extends SpringTxTestCase { @Autowired private ITestRequest testRequest; @Test public void testGet() { String re = testRequest.testGet("北京", "json", "5slgyqGDENN7Sy7pw29IUvrZ"); System.out.println(re); BaiduWeatherEntity entity = JSONUtil.parseJson(re, BaiduWeatherEntity.class); System.out.println(entity.getStatus()); entity = testRequest.testGetEntity("北京", "json", "5slgyqGDENN7Sy7pw29IUvrZ"); System.out.println(JSONUtil.toJson(entity)); }}
public class BaiduWeatherEntity { private String error; private String date; private String status;}可以直接注入接口,获得对象
返回结果
返回的字符串

success自己返回的对象结构{"error":"0","date":"2014-12-12","status":"success"}
因为是简单的测试,就没有建立复杂的对象
说说优点,可以容融合对象,把没有提供jar的API接口,也想java一样接入进来,json可以自动过滤不想要的数据,建立对象不用那么负责,不用一个一个new
URL来处理异常等等
