FastJson之@JSONType注解简介
放在实体类上就会只装配列举的字段或者排除列举的成员变量
@JSONType(ignores ={"id","sex"})//不序列化这两个
public class Pojo2 {
@JSONType(includes ={"name","sex"})//序列化只序列化这两个属性
public class Pojo1 {
demo演⽰
Pojo1
@JSONType(includes ={"name","sex"})//序列化只序列化这两个属性成员变量public class Pojo1 {
private int id;
private String name;
private String sex;
private String password;
private String phone;
//*******************
public int getId(){
return id;
}
public Pojo1 setId(int id){
this.id = id;
return this;
}
public String getName(){
return name;
}
public Pojo1 setName(String name){
this.name = name;
return this;
}
public String getSex(){
return sex;
}
public Pojo1 setSex(String sex){
this.sex = sex;
return this;
}
public String getPassword(){
return password;
}
public Pojo1 setPassword(String password){
this.password = password;
return this;
}
public String getPhone(){
return phone;

public Pojo1 setPhone(String phone){
this.phone = phone;
return this;

}
Pojo2
@JSONType(ignores ={"id","sex"})//不序列化这两个成员变量public class Pojo2 {
private int id;

//************
public int getId(){
return id;
}
public Pojo2 setId(int id){
fastjson忽略属性
this.id = id;
