Question

我有一个Java Restful Web服务，当postman调用时，会返回一个缺少属性的对象。 JSON个对象可以在下面看到。

下面的图片显示了在rest函数中返回之前的对象。正如你所看到的，有一周的日子里有一个没有出现在邮递员身上的价值。

可以在本文末尾查看backAbsence实体。

SAbsence是backAbsence实体的列表。

我想知道为什么当我退回SAbsenece时，邮递员没有收到完整的模型，我该如何解决？

[
    {
        "name": "King sean",
        "classidClass": 0,
        "studentidStudent": 1,
        "week": 14
    },
    {
        "name": "Sean king",
        "classidClass": 0,
        "studentidStudent": 2,
        "week": 14
    }
]

enter image description here

休息功能部分：

@GET
    @Produces({"application/xml","application/json"})
    @Path("{id}/{option}")
    public List<BackAbsence> findbyClass(@PathParam("id")int id,
                                     @PathParam("option")int option) {

List<BackAbsence> SAbsence = new ArrayList<>();

// code here fills list. The Image above shows the object with valid attributes
 return SAbsence;
    }


}

BackAbsnece实体：

public class BackAbsence {

    private String name;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    private int classidClass;

    private int studentidStudent;

    private int monday = 0, tuesday = 0, wednesday = 0, thursday = 0, friday = 0;

    private int week;

     public BackAbsence() {
    }

     public BackAbsence(int idstudent, String name) {
    this.studentidStudent = idstudent;
    this.name = name;
     }

    public BackAbsence(int classidClass, int studentidStudent, int monday, int tuesday, int wednesday, int thursday, int friday,int week) {
        this.classidClass = classidClass;
        this.studentidStudent = studentidStudent;
       this.monday = monday;
       this.tuesday = tuesday;
       this.wednesday = wednesday;
       this.thursday = thursday;
        this.week = week;
    }

    public int isMonday() {
        return monday;
    }

    public void setMonday(int monday) {
        this.monday = monday;
    }

    public int isTuesday() {
        return tuesday;
    }

    public void setTuesday(int tuesday) {
        this.tuesday = tuesday;
    }

    public int isWednesday() {
        return wednesday;
    }

    public void setWednesday(int wednesday) {
        this.wednesday = wednesday;
    }

    public int isThursday() {
        return thursday;
    }

    public void setThursday(int thursday) {
        this.thursday = thursday;
    }

    public int isFriday() {
        return friday;
    }

    public void setFriday(int friday) {
        this.friday = friday;
    }


     public int getClassidClass() {
        return classidClass;
    }

    public void setClassidClass(int classidClass) {
        this.classidClass = classidClass;
    }

    public int getStudentidStudent() {
        return studentidStudent;
    }

    public void setStudentidStudent(int studentidStudent) {
        this.studentidStudent = studentidStudent;
    }



    public int getWeek() {
        return week;
    }

    public void setWeek(int week) {
        this.week = week;
    }

}

Answer 1

在我看来，无论你用来进行转换的json mapper实现只是寻找java bean样式的getter和setter，所以忽略了像isMonday（）这样的int方法。尝试将它们更改为getMonday（）或查找不同的映射器实现。

Answer 2

HRM。你正在使用＆＃34;布尔＆＃34;样式getter获取int字段。

 private int monday = 0, tuesday = 0, wednesday = 0, thursday = 0, friday = 0;

尝试将此更改为getMonday，getTuesday等或将整数更改为bools。
