单元测试：

public class TestMongo {@Testpublic void testInsert() throws JsonProcessingException{Log log = new Log();log.set_id(UUIDUtil.getUUID());log.setOperateType("修改");Mongo.insert(log);}@Testpublic void testQueryList() throws JsonParseException, JsonMappingException, IOException{Bson filter = eq("operateType", "修改");List<Log> list = Mongo.find(filter, Log.class);}}
