java - JAXB propOrder 标题大小写标签不起作用

Question

我需要在使用 jaxb 进行编码后维护标签顺序，其中 xml 标签是首字母大写。尝试编码时抛出以下错误。

“存在属性 applicationCountFromDate 但未在 @XmlType.propOrder 中指定”

请在下面找到完整的堆栈和代码。

问题原始版本的答案

JAXB 认为方法 getApplicationCountToDate() 对应于属性 applicationCountToDate(注意它以小写字母开头)，因此它期望 applicationCountToDate 在 propOrder 而不是 ApplicationCountToDate 中。在这种情况下，您会得到一个很好的异常，为您指明正确的方向。

Property applicationCountToDate is present but not specified in @XmlType.propOrder
    this problem is related to the following location:
        at public java.lang.String com.snapwork.bean.login.LoginRESBean.getApplicationCountToDate()
        at com.snapwork.bean.login.LoginRESBean
        at public com.snapwork.bean.login.LoginRESBean com.snapwork.bean.login.LoginMBBean.getRS()
        at com.snapwork.bean.login.LoginMBBean

我在我的博客上写了更多关于 propOrder 的内容:

更新

使用更新后的模型，您应该会遇到以下异常:

Property applicationCountFromDate is present but not specified in @XmlType.propOrder
    this problem is related to the following location:
        at public java.lang.String forum27147537.LoginRESBean.getApplicationCountFromDate()
        at forum27147537.LoginRESBean

对于您问题中的更新代码，我唯一需要做的就是将 applicationCountFromDate 添加到 propOrder 以使一切正常:

@XmlType (propOrder = {"operationStatus",
        "operationErrorCode",
        "operationErrorMessage",
        "JSessionID",
        "DSACode",
        "displayName",
        "applicationCountToDate",
        "applicationCountFromDate",
        "totalAppliationCount",
        "approvedApplicationCount",
        "submittedApplicationCount",
        "declineApplicationCount"
})
