当使用 java 1.7 编译器

通过 eclipse 进行 maven 全新安装时，我遇到了上述异常

但是如果我将 java 编译器更改为 1.8，它就可以正常工作。但我想在 JBoss 服务器上部署这个 jar，它有 java 1.7 版本。

请帮忙解决这个问题。提前致谢。

您应该在绑定文件中声明您的 icm 前缀。

将 xmlns:icm="<URI of the icm namespace here>" 添加到根元素。

这与 JAXB 关系不大，而与 XML 关系更大。 JAXB 期望 "qualified name" 为 @xmlType。 "Qualified name" 表示必须定义前缀并指向正确的命名空间。
