Jackson 注解 - @JsonIgnoreProperties
@JsonIgnoreProperties 在类级别使用来标记要忽略的属性或属性列表。
示例 - @JsonIgnoreProperties
import java.io.IOException; import com.fasterxml.jackson.annotation.JsonIgnoreProperties; import com.fasterxml.jackson.databind.ObjectMapper; public class JacksonTester { public static void main(String args[]) { ObjectMapper mapper = new ObjectMapper(); try { Student student = new Student(1,11,"1ab","Mark"); String jsonString = mapper .writerWithDefaultPrettyPrinter() .writeValueAsString(student); System.out.println(jsonString); } catch (IOException e) { e.printStackTrace(); } } } @JsonIgnoreProperties({ "id", "systemId" }) class Student { public int id; public String systemId; public int rollNo; public String name; Student(int id, int rollNo, String systemId, String name){ this.id = id; this.systemId = systemId; this.rollNo = rollNo; this.name = name; } }
输出
{ "rollNo" : 11, "name" : "Mark" }
