如何使用jaxb读取属性？ [英] How do I read attributes using jaxb?

问题描述

鉴于此XML：

<response>
    <detail Id="123" Length="10" Width="20" Height="30" />
</response>

这就是我现在所拥有的，但它无效（我得到空结果）：

This is what I have now, but it is not working (I'm getting empty result):

@XmlRootElement(name="response")
public class MyResponse {
    List<ResponseDetail> response;
    //+getters +setters +constructor
}

public class MyResponseDetail {
    Integer Id;
    Integer Length;
    Integer Width;
    Integer Height;
    //+getters +setters
}

我正在打电话使用 RestOperations 到远程服务，我想解析< detail ..> 元素。我已经尝试将 MyResponse 和 MyResponseDetail 类传递给 RestOperations 但结果总是空的。

I'm making a call to a remote service using RestOperations and I want to parse the <detail ..> element. I've tried passing both MyResponse and MyResponseDetail classes to RestOperations but the result is always empty.

我的对象结构应该与该XML匹配？

What should my object structure look like to match that XML?

推荐答案

你需要像这样注释你的类：

You need to annotate your classes like that:

@XmlRootElement
public class Response {

    private List<Detail> detail;

    public void setDetail(List<Detail> detail) {
        this.detail = detail;
    }
    public List<Detail> getDetail() {
        return detail;
    }

}

public class Detail {

    private String id;
    /* add other attributes here */

    @XmlAttribute(name = "Id")
    public void setId(String id) {
        this.id = id;
    }
    public String getId() {
        return id;
    }

}
