jackson的使用

@JsonIgnore：排除json序列化，将它标注在属性上不会进行json序列化

@JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss",locale = "zh")：进行日期格式化

@JsonInclude(JsonInclude.Include.NON_NULL)：当属性值为null时则不进行json序列化

@JsonProperty("uname")：属性设置别名

package boot.bean;
import com.fasterxml.jackson.annotation.*;
import java.util.Date;

public class User {
    @JsonInclude(JsonInclude.Include.NON_NULL)
    @JsonProperty("uname")
    private String name;
    @JsonIgnore
    private int age;
    @JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss")
    private Date birthday;

    public User(String name, int age, Date birthday) {
        this.name = name;
        this.age = age;
        this.birthday = birthday;
    }

    public String getName() {
        return name;
    }

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

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

    public Date getBirthday() {
        return birthday;
    }

    public void setBirthday(Date birthday) {
        this.birthday = birthday;
    }

    @Override
    public String toString() {
        return "User{" +
                "name='" + name + '\'' +
                ", age=" + age +
                ", birthday=" + birthday +
                '}';
    }
}
