几乎相同的webapps在提供静态内容方面表现不同

使用Spring-Hibernate设置从webapp提供静态内容时遇到“奇怪”问题。

我有一个(小)webapp,它使用DispatcherServlet来提供这样的任何URL:/ coverpage / *。默认的servlet映射设置为/ static / *

示例:

<servlet-mapping>
    <servlet-name>default</servlet-name>
    <url-pattern>/static/*</url-pattern>
</servlet-mapping>

<servlet>
    <servlet-name>dispatcher</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <load-on-startup>2</load-on-startup>
</servlet>

<servlet-mapping>
    <servlet-name>dispatcher</servlet-name>
    <url-pattern>/coverpage/*</url-pattern>
</servlet-mapping>

在我的jsp中,静态内容(images / js / css)是这样写的:

<spring:url value="/static/styles/js/jquery-1.4.2.min.js" />

我在webapp中有4个页面:index.jsp,new.jsp,error.jsp和includes.jsp(不是实际的页面,duh)和/ process的映射,它返回PDF内容或验证 - 输入错误数据时出错。

此设置似乎在我的webapp中正常工作。

现在对于奇怪的部分: 我在另一个Tomcat实例上部署了相同的webapp并更改了端口,以便它们可以同时运行,现在对静态内容的引用只能工作一半。只有/ new(又名new.jsp)的映射才能找到静态内容。其余的都无法加载它。

2个实例之间的差异

  • Tomcat版本(原始版本在6.0.29上运行,第二个实例在6.0.33上运行)

  • Tomcat端口

  • 数据库连接(原始转到PROD db,第二个实例转到TEST db - 两个数据库都相同)

这是我的web.xml

答案 0 :(得分:0)

问题在于Tomcat版本。我尝试在新下载的6.0.29 Tomcat而不是6.0.33上运行第二个实例,它似乎工作正常。我将通过Tomcat更改日志尝试查找导致此问题的原因...如果我找到任何内容,我会在此处报告。
