经过一番百度,解决方案:

方案1、在web.xml中加入

<servlet>
      <servlet-name>servletContainer</servlet-name>
      <servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>
   </servlet>

注意ServletContainer这个类在jersey-servlet.jar中,项目lib中没有引入这个jar,但weblogic启动后,没有异常,正常启动,解决 了问题,但是tomcat或jetty部署,没有相关jar,肯定报错的

方案2、项目中引入jersey-servlet.jar,web.xml不用额外配置servlet,这样weblogic、tomcat、jetty启动都正常了。

以上是解决方案,但是有个疑问,为什么web.xml为servlet2.4,不用添加任何有关jersey的jar,而且项目也确实没有使用任何有关jersey的东西,一旦切换成3.0后,weblogic就会扫描jersey的东西,weblogic有没有什么配置可以关掉这个扫描?不想多加这个无关的jar引用,或者有能解释原因的大神
