Question

你能帮我吗？我有一个部分

的xml文件

<time-layout time-coordinate="local" summarization="none">
<layout-key>k-p24h-n7-1</layout-key>
<start-valid-time>2015-08-10T08:00:00-04:00</start-valid-time>
<end-valid-time>2015-08-10T20:00:00-04:00</end-valid-time>
<start-valid-time>2015-08-11T08:00:00-04:00</start-valid-time>
<end-valid-time>2015-08-11T20:00:00-04:00</end-valid-time>
<start-valid-time>2015-08-12T08:00:00-04:00</start-valid-time>
<end-valid-time>2015-08-12T20:00:00-04:00</end-valid-time>
<start-valid-time>2015-08-13T08:00:00-04:00</start-valid-time>
<end-valid-time>2015-08-13T20:00:00-04:00</end-valid-time>
<start-valid-time>2015-08-14T08:00:00-04:00</start-valid-time>
<end-valid-time>2015-08-14T20:00:00-04:00</end-valid-time>
<start-valid-time>2015-08-15T08:00:00-04:00</start-valid-time>
<end-valid-time>2015-08-15T20:00:00-04:00</end-valid-time>
<start-valid-time>2015-08-16T08:00:00-04:00</start-valid-time>
<end-valid-time>2015-08-16T20:00:00-04:00</end-valid-time>
</time-layout>

并使用bean转换

public class TimeLayout {

    @JacksonXmlProperty( localName = "time-coordinate" , isAttribute = true)
    private String timecoordinate;

    @JacksonXmlProperty( localName = "summarization" , isAttribute = true)
    private String summarization;

    @JacksonXmlProperty( localName = "layout-key" , isAttribute = false)
    private String key;

    @JacksonXmlProperty( localName = "start-valid-time" , isAttribute = false)
    @JacksonXmlElementWrapper(useWrapping = false)
    private List<String> startvalidtime;

    @JacksonXmlProperty( localName = "end-valid-time" , isAttribute = false)
    @JacksonXmlElementWrapper(useWrapping = false)
    private List<String> endvalidtime;

但是从Jackson库中通过XML Mapper解析我们只得到一对值（最后一个）

<start-valid-time>2015-08-16T08:00:00-04:00</start-valid-time>
<start-valid-time>2015-08-16T20:00:00-04:00</end-valid-time>

因为每个next或（从一开始）都有自己的上下文并设置之前的值但不会添加到列表中。

调试映射问题的常用方法是从POJO开始（以编程方式构造实例），然后序列化（写为XML），并查看结构的不同之处。从中可以修改注释，Jackson XML模块配置，或者可能是POJO定义。
