[英]spring boot offsetDateTime in query param
我嘗試創建以下 api:
@GetMapping("/workerslist")
public List<Worker> getWorkersList(
@RequestParam(name = "lastPollBefore", required = false) OffsetDateTime lastPollBefore,
@RequestParam(name = "lastPollAfter", required = false) OffsetDateTime lastPollAfter){
return workerService.getWorkers(lastPollBefore, lastPollAfter);
}
但是當我調用它時,出現以下錯誤:
{
"_type": "ValidationError",
"key": "validation-error",
"message": "Failed to convert value of type 'java.lang.String' to required type 'java.time.OffsetDateTime'; nested exception is org.springframework.core.convert.ConversionFailedException: Failed to convert from type [java.lang.String] to type [@org.springframework.web.bind.annotation.RequestParam java.time.OffsetDateTime] for value '2020-07-01T11:52:57.152Z'; nested exception is java.lang.IllegalArgumentException: Parse attempt failed for value [2020-07-01T11:52:57.152Z]",
"constraints": [
]
}
我找到了 localDateTime 的解決方案,但它們似乎不適用於 offsetDateTime,
您需要為 controller 中的 OffsetDateTime arguments 添加@DateTimeFormat注釋。例如。
@GetMapping("/workerslist")
public List<Worker> getWorkersList(
@RequestParam(name = "lastPollBefore", required = false) @DateTimeFormat(iso = DateTimeFormat.ISO.DATE_TIME)OffsetDateTime lastPollBefore,
@RequestParam(name = "lastPollAfter", required = false) @DateTimeFormat(iso = DateTimeFormat.ISO.DATE_TIME)OffsetDateTime lastPollAfter){
return workerService.getWorkers(lastPollBefore, lastPollAfter);
}
您可能希望通過您自己的自定義映射器覆蓋 Spring 的默認 Object 映射器。
是這樣的:
@Configuration
public class JsonConfiguration {
private static final ObjectMapper OBJECT_MAPPER =
new ObjectMapper().registerModule(new JavaTimeModule())
.disable(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS)
.disable(DeserializationFeature.ADJUST_DATES_TO_CONTEXT_TIME_ZONE)
.disable(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES);
@Bean
@Primary
public static ObjectMapper getObjectMapper() {
return OBJECT_MAPPER;
}
}
