java - 我正在 weblogic 12.2.1.2 上部署一个restFull webservice webapp，但它失败了

Question

您好，我有一个 Restfull Web 服务，该服务在 weblogic 12.2.1.2 版本之前部署，但在 weblogic 12.2.1.2 上它没有部署。并抛出以下错误:

<Oct 11, 2017, 8:16:22,462 PM IST> <Warning> <Munger> <BEA-2156203> <A version attribute was not found in element "web-app" in the deployment descriptor /u01/xxx/xxxx/webapps/xx/WEB-INF/web.xml. A version attribute is required, but this version of the WebLogic Server will assume that the latest version is used. Future versions of WebLogic Server will reject descriptors that do not specify the Java EE version. To eliminate this warning, add an appropriate "version=" to element "web-app" in the deployment descriptor.>

我尝试过使用 web.xml 中的 version 属性，但没有成功。并抛出同样的错误。

环境。详情:

Java-1.7 & 1.8
weblogic-12.2.1.2
Servlet-api-2.4

任何帮助将不胜感激..

这是来自 Jersey Examples 的 web.xml 示例，请注意有一个初始化参数指向 Jersey 应用程序类

<web-app version="2.5" 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_2_5.xsd">

    <filter>
        <filter-name>org.glassfish.jersey.examples.bookstore.webapp.MyApplication</filter-name>
        <filter-class>org.glassfish.jersey.servlet.ServletContainer</filter-class>
        <init-param>
            <param-name>javax.ws.rs.Application</param-name>
            <param-value>org.glassfish.jersey.examples.bookstore.webapp.MyApplication</param-value>
        </init-param>
        <!-- pass to next filter if Jersey/App returns 404 -->
        <init-param>
            <param-name>jersey.config.servlet.filter.forwardOn404</param-name>
            <param-value>true</param-value>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>org.glassfish.jersey.examples.bookstore.webapp.MyApplication</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
</web-app>

这是应用程序类:

public class MyApplication extends ResourceConfig {
    public MyApplication() {
        // Resources.
        packages(Bookstore.class.getPackage().getName());

        // MVC.
        register(JspMvcFeature.class);

        // Logging.
        register(LoggingFilter.class);

        // Tracing support.
        property(ServerProperties.TRACING, TracingConfig.ON_DEMAND.name());
    }
}
