如何在java中创建一个自定义@jsonDeserializer类
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。 请帮助我反序列化这个类。 我的班就是这样..
@Entity @Table（name =“A”，uniqueConstraints = @UniqueConstraint（columnNames = {“name”}））@JsonIdentityInfo（generator = ObjectIdGenerators.IntSequenceGenerator.class，property =“@_ refid”）@JsonDeserialize（using = ADeSerializer。类）public class 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
}
清楚地说...
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;
}
// Getters和setters
}
我的休息服务是
@RequestMapping（value =“/ saveA”，method = RequestMethod.POST）public @ResponseBody MIResponse saveA（@RequestBody A a）throws Exception {
return null;
}
