将json序列化为list<T>:

List<SysWarnSetting> listByEntity2 = new ObjectMapper().readValue(str, new

TypeReference<List<SysWarnSetting>>() {});

JavaType javaType = objectMapper.getTypeFactory().constructParametricType(List.class,

SysWarnSetting.class);

sysWarnSettings = objectMapper.readValue(sysWarnSettingListJson,javaType);
