java - 如何在 java 中创建自定义 @jsonDeserializer 类

Question

我有一个java类。这与许多其他java类有关。我想反序列化这个类。请帮我反序列化课程。我的课是这样的。。

@Entity @Table(name = "A", uniqueConstraints = @UniqueConstraint(columnNames = { "name" })) @JsonIdentityInfo(generator=ObjectIdGenerators.IntSequenceGenerator.class, property="@_refid") @JsonDeserialize(using=ADeSerializer.类）公共类A {

@Column(name = "name")
private String name;

@Column(name = "DESCRIPTION")
private String description;

//

@ManyToMany(cascade={CascadeType.REMOVE, CascadeType.MERGE},fetch=FetchType.EAGER)
@JoinTable(
        name="B",
        joinColumns={@JoinColumn(name="Aname")},
        inverseJoinColumns={@JoinColumn(name="Bname", unique=true)}
    )
@Fetch(FetchMode.SUBSELECT)
private Set<C> cs;

@ManyToMany(cascade={CascadeType.MERGE},fetch=FetchType.EAGER)
@JoinTable(
        name="D",
        joinColumns=@JoinColumn(name="Aname"),
        inverseJoinColumns=@JoinColumn(name="Ename")
    )
@Fetch(FetchMode.SUBSELECT)
private Set<E> Es;

@Cascade({org.hibernate.annotations.CascadeType.DELETE_ORPHAN})
@ManyToMany(cascade={CascadeType.ALL, CascadeType.MERGE},fetch=FetchType.EAGER)
@JoinTable(
        name="F",
        joinColumns=@JoinColumn(name="Aname"),
        inverseJoinColumns=@JoinColumn(name="Fname")
    )
@Fetch(FetchMode.SUBSELECT)
private Set<F> Fs;



// Getters and setters

}

说清楚...

 Class A {
        Object of Class B;
        Object of Class C {
                  Set<ClassB> bs;
               Objects of Class C;
               Object of Class A
          }
       other local variables;

      Objects of Class D{
             set<ClassB> ds;
        }

//getter 和 setter

}

我的休息服务是

@RequestMapping(value="/saveA", method=RequestMethod.POST) public @ResponseBody MIResponse saveA(@RequestBody A a) 抛出异常{

    return null;
}
