我想在每次請求日期時使用DateTimeFormat.ISO.DATE配置Jackson，例如：

@RequestMapping(value = "income")

public ResponseEntity calculateIncome(

@RequestParam(value = "companyName") String companyName,

@DateTimeFormat(iso = DateTimeFormat.ISO.DATE)

@RequestParam(value = "startDate") LocalDate startDate,

@DateTimeFormat(iso = DateTimeFormat.ISO.DATE)

@RequestParam(value = "endDate") LocalDate endDate

)

我已經(jīng)嘗試過在JacksonConfig中設(shè)置它

mapper.enable(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS);

要么

mapper.disable(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS);

也

mapper.configure(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS, false);

要么

mapper.configure(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS, true);

甚至在我試過的application.properties中

spring.jackson.serialization.write_dates_as_timestamps=true

我正在使用spring-boot機(jī)智跟隨依賴項

org.springframework.boot

spring-boot-starter-web

1.5.10.RELEASE

com.fasterxml.jackson.datatype

jackson-datatype-jsr310

${jackson.version}

我只是不想重復(fù)相同的@DataTimeFormat，但沒有它，我仍然會收到錯誤：
