在集成Spring和jersey的同时在web.xml中指定context-param

时间：2015-10-05 10:02:01

标签： java xml spring maven

我知道已就此主题提出问题，但未得到答复Application not workig when adding value to <context-param> in web.xml in Spring MVC Web Application Using Maven

我正在尝试集成Spring和jersey，当我添加context-param标签来指定applicationContext.xml时，应用程序将不会加载主页（webContent文件夹下的index.jsp），如果该标签被重新移动，则应用程序加载主页，但thrn我将无法指定spring（applicationContext.xml）

的配置

这是我的web.xml：

applicationContext.xml位于类路径（即src文件夹）中，web.xml位于WEB-INF下，index.jsp位于WebContent下

基本问题是你混淆了xml和annotationConfigs。 您需要知道 contextClass 和 contextConfigLocation 上下文参数之间的关系以及ContextLoaderListener将如何使用它。

  1. contextClass：指配置类。你在这里提到它是org.springframework.web.context.support.AnnotationConfigWebApplicationContext
  2. contextConfigLocation：这是spring的bo​​otstraper将搜索config的位置。您将contextClass指定为AnnotationConfigWebApplicationContext，为此您应该给出Spring bean配置类所在的包名称。我假设您使用@Configuration注释了这样的类

    3. 如果没有这样的@Configuration注释类，则删除contextClass并仅将contextConfigLocation参数与xml路径一起作为值。默认情况下ContextLoaderListener采用基于xml的。 以下是migrate to java config from xml based spring

    的示例

    您可以找到适合球衣整合here的示例。

    接下来我仍然感到困惑，为什么你使用RequestContextListener进行REST应用。如果您根据its documentation没有任何特殊目的，请将其删除。如果您想使用它，example将有助于
