Tomcat 8 java.lang.LinkageError：加載程序約束沖突

Question

我在啟用了security manager tomcat上部署了Web服務（使用METRO 2.0庫並將其包含在war文件中）

-Djava.security.manager
-Djava.security.policy=C:\apache-tomcat-8.5.6\conf\catalina.policy

我收到以下異常

    SEVERE [localhost-startStop-1]

另一方面，如果沒有security manager ，一切都會很好地部署。

經過一番搜索之后，我開始理解問題是在tomcat庫和METRO 2.0中都找到了javax/xml/bind/annotation/XmlNsForm 。

所以我有兩個問題：

1. catalina.policy中是否可以設置某種屬性來避免此問題。

2.是否有其他方法可以解決此沖突而無需從war刪除Metro 2.0 。

提前致謝。

Answer 1

因此，解決方案是不使用整個Metro 2.0捆綁軟件-僅使用捆綁軟件的某些庫（作為jars添加，而不是作為netbeans整個捆綁軟件添加）
