使用jackson自定義`JsonSerializer `和 `JsonDeserializer`,通過`@JsonComponent`就可以簡單的直接注冊bean. `@JsonComponent`可以直接用在`JsonSerializer` 或 `JsonDeserializer`實現類上,也可以用在包含serializers/deserializers的內部類,如下: ~~~ import java.io.*; import com.fasterxml.jackson.core.*; import com.fasterxml.jackson.databind.*; import org.springframework.boot.jackson.*; @JsonComponent public class Example { public static class Serializer extends JsonSerializer<SomeObject> { // ... } public static class Deserializer extends JsonDeserializer<SomeObject> { // ... } } ~~~
