未能類型的屬性值轉換[java.lang.String中]所需類型[java.time.LocalDate]

{ 
"toDepartureDate": "2016-12-28", 
"fromDepartureDate": "2016-12-28" 
}

我要張貼上面的字符串在JSON作爲java.time.LocalDate日期，但我收到400錯誤的請求爲錯誤。有人能幫忙嗎？我用@JsonFormat，但它也沒有幫助我。未能類型的屬性值轉換[java.lang.String中]所需類型[java.time.LocalDate]

@JsonFormat(shape=JsonFormat.Shape.STRING,pattern="yyyy-MM-dd",timezone = "GMT+5:30") 

private LocalDate fromDepartureDate; 

@JsonFormat(shape=JsonFormat.Shape.STRING,pattern="yyyy-MM-dd",timezone = "GMT+5:30") 
private LocalDate toDepartureDate;
