java - 所有字段都需要添加@Element注解吗？

Question

如果我有一个包含 20 个字段的类，我是否需要在每个字段上添加 @Element 注释？有没有办法告诉简单框架采取所有？

Answer 1

不，您可以使用@Default注释:

The Default annotation is used to specify that all fields or methods should be serialized in a default manner. This basically allows an objects fields or properties to be serialized without the need to annotate them.

除了@Default之外，您仍然可以使用自定义注释作为@Element:

@Root
@Default
public static class Example
{
    private int value = 3;
    private String string = "abc";

    @Element(name = "some-custom-name")
    private String customString = "custom";

    // ...
}

输出:

<example>
   <value>3</value>
   <string>abc</string>
   <some-custom-name>custom</some-custom-name>
</example>
