当我尝试读取我得到的 xlm 文件时我明白了

when i try to read the xlm file i get i get

com.sun.xml.internal.bind.v2.runtime.IllegalAnnotationsException: 1 counts of IllegalAnnotationExceptions
Class has two properties of the same name "timeSeries"
    this problem is related to the following location:
        at public java.util.List testjaxp.ModeleREP.getTimeSeries()
        at testjaxp.ModeleREP
    this problem is related to the following location:
        at protected java.util.List testjaxp.ModeleREP.timeSeries
        at testjaxp.ModeleREP

我不明白这个错误

我使用 jaxb-impl-2.1.12

edit: i use jaxb-impl-2.1.12

好的，现在我没有任何错误，但是当我检查我的对象时，timeSeries 为空...

ok now i don't have any error, but when i check my object, timeSeries is null...

所以也许 jaxb 似乎对 flx 有问题?

so maybe jaxb seem to have problem with flx?

推荐答案

我也遇到过这样的问题，我设置了这个.

I also faced problem like this and i set this.

@XmlRootElement(name="yourRootElementName")
@XmlAccessorType(XmlAccessType.FIELD)

这将工作 100%
