jakarta-ee - 将 web.xml 从 Java EE 5 迁移到 Java EE 6 时出错

Question

自从我将 web.xml 从 Java-EE-5 迁移到 Java-EE-6 后，我的应用程序出现问题。这是我部署应用程序时得到的堆栈跟踪:

来自 web.xml 的 header :

<web-app xmlns="http://java.sun.com/xml/ns/javaee"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
      version="3.0"> 

根.xml:

<?xml version="1.0" encoding="UTF-8"?>
<Context docBase="/home/julien/Documents/jeanbaptistemartin.com/java/site/jeanbaptistemartin/target/ROOT" path="/ROOT"/>

Answer 1

This blog post (在@balteo上面的评论中)有答案:

在 web.xml 中添加 metadata-complete="true"以覆盖注释的默认属性 3.0。默认情况下，Tomcat 7 将扫描所有类文件以查找注释，并尝试部署使用它理解的 Web 描述符找到的任何类。设置 metadata-complete 告诉 tomcat web.xml 和其他描述 rune 件是完整的，不要打扰注释。

这个解决方案似乎有效，但它并没有真正让我满意，因为我一直在多个 tomcat 7 服务器上部署相同的 war 没有问题，但是当我们最终部署到生产时，我们得到了这个错误。我仍然不确定为什么我们的生产服务器与测试服务器有什么不同。
