Spring Cloud通過Feign請求返回值LocalDateTime異常

問題描述:

通過openFeign調用接口, 請求能達到服務, 但是返回值中含有LocalDateTime類型參數, 報以下錯誤:

feign.codec.DecodeException: Type definition error: [simple type, class java.time.LocalDateTime]; nested exception is com.fasterxml.jackson.databind.exc.InvalidDefinitionException: Cannot construct instance of `java.time.LocalDateTime` (no Creators, like default construct, exist): no String-argument constructor/factory method to deserialize from String value ('2020-05-20T16:00:32')
Caused by: org.springframework.http.converter.HttpMessageConversionException: Type definition error: [simple type, class java.time.LocalDateTime]; nested exception is com.fasterxml.jackson.databind.exc.InvalidDefinitionException: Cannot construct instance of `java.time.LocalDateTime` (no Creators, like default construct, exist): no String-argument constructor/factory method to deserialize from String value ('2020-05-20T16:00:32')
Caused by: com.fasterxml.jackson.databind.exc.InvalidDefinitionException: Ca

解決方案:

引入依賴:

<dependency>
     <groupId>com.fasterxml.jackson.datatype</groupId>
     <artifactId>jackson-datatype-jsr310</artifactId>
     <version>2.10.3</version>
