java - 如何在 Eclipse 中导出或保存检查的对象结构？

Question

有没有办法保存/导出(也需要能够稍后查看)检查的对象结构？

可能导出为 XML 或 JSON 结构？

Answer 1

您可以使用 xstream ，例如

Java 对象:

 public class Person {
      private String firstname;
      private String lastname;
      private PhoneNumber phone;
      private PhoneNumber fax;
      // ... constructors and methods
    }

public class PhoneNumber {
  private int code;
  private String number;
  // ... constructors and methods
}'

简单实例化 XStream 类:

XStream xstream = new XStream();

创建一个 Person 实例并填充其字段:

Person joe = new Person("Joe", "Walnes");
joe.setPhone(new PhoneNumber(123, "1234-456"));
joe.setFax(new PhoneNumber(123, "9999-999"));

将其转换为 XML

String xml = xstream.toXML(joe);'

结果

<person>
  <firstname>Joe</firstname>
  <lastname>Walnes</lastname>
  <phone>
    <code>123</code>
    <number>1234-456</number>
  </phone>
  <fax>
    <code>123</code>
    <number>9999-999</number>
  </fax>
</person>
