我有一个将使用xml数据的Web服务
@Override
@GET
@Consumes("*/*")
@Produces("application/xml")
@Path("page/{id}")
public PageData getPage(@QueryParam("session") final String sessionId,
@PathParam("id") final String valueId)
throws SessionNotFoundException {
final PageData pageData= getPageData(valueId);
return pageData;
}
启动wildfly服务器时，我收到以下异常

另一件事是，如果我将我的Jars添加到eclipse并从eclipse运行我没有得到任何异常，但是如果我从WildFly构建我的应用程序并编写脚本并部署，那么只有我得到了Exception。
我怀疑这是由于JAR不匹配，但我在两种情况下都有相同的罐子。
如果有人知道答案，请建议。
答案 0 :(得分：1)
线索在这里
getPage（java.lang.String， java.lang.Object ）
这意味着，正如您所想，您之前看到的代码不是在服务器上部署的代码。
对我来说，通常的原因是我通过将WAR粘贴到Wildfly独立/部署文件夹中来部署代码，然后尝试使用Wildfly Maven插件部署更新的版本。一切都会在Maven中成功，但我粘贴到deployments文件夹中的版本将继续优先于Maven版本。
顺便说一下，无法找到构造函数错误的常见原因是将Collection用作@QueryParam。这似乎很直观，但Resteasy不支持，您需要使用List。
