我使用URL访问REST API,它给出了以下JSON结果:
{"size":1,"filter":{"applicationName":"xx.x1",
"fromTimestamp":1261746800000,
"toTimestamp":1361833200000,
"company":"xx",
"groupedBy":"COMPANY_APPLICATION"},
"values"[{"applicationName":"xx.x1","count":17,"company":"xx"}],
"start":0,"limit":25,"lastPage":true}
使用Jackson我尝试以这种方式解析json:
ObjectMapper mapper = new ObjectMapper();
try {
ErrorDataRest error = mapper.readValue(url, ErrorDataRest.class);
Map<String,Object> map = mapper.readValue(url, Map.class);
如果我使用第一个或第二个,无关紧要,我得到这个例外:
