我需要?jiǎng)?chuàng)建一個(gè)新的注釋，用于在環(huán)境變量var == false. 我嘗試使用JsonAnnotationIntrospector，但無法獲得預(yù)期的輸出。public class Vehicle {    String vehicle_name;    String vehicle_model;    //getters and setters      @MyAnnotation    public String getVehicle_model() {        return vehicle_model;    }}這里我需要?jiǎng)h除vehicle_model環(huán)境變量時(shí)的屬性var == false。@Retention(RetentionPolicy.RUNTIME)@Target({ElementType.METHOD})@JsonIgnorepublic @interface MyAnnotation {}這是我自定義注解的聲明。有人可以告訴我應(yīng)該如何編寫 Introspector 部分以獲得我需要的功能嗎？提前致謝。編輯：我的嘗試 JacksonAnnotationIntrospectorpublic class MyAnnotationIntrospector extends JacksonAnnotationIntrospector {@Overridepublic boolean hasIgnoreMarker(AnnotatedMember annotatedMember) {    //need this part   } }的實(shí)現(xiàn)ObjectMapper是 ObjectMapper mapper = new ObjectMapper(); String json = mapper.writerWithDefaultPrettyPrinter().writeValueAsString(this);
