如何让@JsonIgnore工作我有一堂课.即使我把注释放在那里它对输出也没有影响.我在用杰克逊.

public class QuestionBlock implements ComparableByID{


    int ID;

    String title;
    String description;
    boolean deleted;
    boolean isDraft;
    boolean visible;
    Timestamp modifiedDate;
    String modifiedBy;


    private List<Question> questions =  new ArrayList<>();

    @JsonIgnore
    private List<Survey> surveys =  new ArrayList<>();

    ...

    @JsonIgnore
    public List<Survey> getSurveys() {
        return surveys;
    }

    @JsonIgnore
    public void setSurveys(List<Survey> surveys) {
        this.surveys = surveys;
    }

}

这是我的Controller方法:

@RequestMapping(value = "/questionBlock/{id}",produces = "application/json;charset=UTF-8")
    @ResponseBody
    public QuestionBlock getQuestionBlock(@PathVariable("id") int id) {
        return surveyService.getQuestionBlock(id);
    }

这是我的servlet-context.xml:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc"
