java - 从 Xmappr 更改为 BeanIO

Question

当我想用Xmappr注释指定java类中XML元素的属性时，我使用@Attribute注释，例如:

exampleclass.java:

@Attribute("Code")
private String code;

它正在映射Brand元素的属性Code

Brand.xml:

<Brand Code="123">
    <Description>Name</Description>
    <BrandName>true</BrandName>
</Brand>

我的任务是将Xmappr注释更改为BeanIO。

我可以使用@Field注释映射单个元素(没有属性)，例如:

@Field(xmlName="Description")
Private String description;

所以问题是，如何使用 BeanIO 将属性 Code 获取到 java 类？我需要将 xml 更改为:

<Brand>
    <BrandCode>123</BrandCode>
    <Description>Name</Description>
    <BrandName>true</BrandName>
</Brand>

然后在代码上使用@Field注释，或者还有其他方法吗？

Answer 1

你可以使用

@Field(xmlType=XmlType.ATTRIBUTE)

您的代码将变为:

@Field(xmlName="Code", xmlType=XmlType.ATTRIBUTE)
private String code;

5.7 Fields

A field is mapped to XML using the field's xmlType attribute, which defaults to element. The field XML type can be set to element, attribute, text, or none.

6.2 Annotations

When using annotations, it is strongly recommended to explicitly set the position (using at) for all fields and segments. BeanIO does not guarrantee the order in which annotated components are added to a layout.

Annotation settings are generally named according to their mapping file counterparts and follow the same convention as well.
