JsonConfig 類別是一個幫助配置序列化過程的實用類別。我們可以使用JsonConfig 類別的setExcludes()方法將一個bean轉換為一個JSON對象,並排除其中的一些屬性,並將這個JSON配置實例傳遞給JSONObject的靜態方法fromObject()的參數。
public void setExcludes(String[] excludes)
In the below example, we can convert bean to a JSON object by excluding some of the properties.
import net.sf.json.JSONObject; import net.sf.json.JsonConfig; public class BeanToJsonExcludeTest { public static void main(String[] args) { Student student = new Student("Raja", "Ramesh", 35, "Madhapur"); JsonConfig jsonConfig = new JsonConfig(); jsonConfig.setExcludes(new String[]{"age", "address"}); JSONObject obj = JSONObject.fromObject(student, jsonConfig); System.out.println(obj.toString(3)); //pretty print JSON } public static class Student { private String firstName, lastName, address; private int age; public Student(String firstName, String lastName, int age, String address) { super(); this.firstName = firstName; this.lastName = lastName; this.age = age; this.address = address; } public String getFirstName() { return firstName; } public String getLastName() { return lastName; } public int getAge() { return age; } public String getAddress() { return address; } } }
#在下面的輸出中,age 和address 屬性可以被排除。
{ "firstName": "Raja", "lastName": "Ramesh" }##
以上是如何在Java中使用JsonConfig將bean轉換為JSON物件並排除某些屬性?的詳細內容。更多資訊請關注PHP中文網其他相關文章!
