我有带有 Spring 和 Spring 安全性的 web 项目。我的 web.xml:
<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" >
<display-name>BillBoard

<session-config>
<session-timeout>

<listener>

</servlet>
<servlet-mapping>
<servlet-name>billboard</servlet-name>
<url-pattern>*.html</url-pattern>
</servlet-mapping>
<filter>
<filter-name>springSecurityFilterChain</filter-name>

</web-app>
在服务器日志中,我看到 Spring 上下文被加载了两次(spring bean 初始化、数据库创建......)。第一次是 DispatcherServlet,第二次是 ContextLoaderListener。我该如何解决?
在本教程中,我看到如果提供了 contextParam,则不需要 servlet init-params。但是如果我删除初始化参数我有错误:“org.apache.catalina.LifecycleException: org.apache.catalina.LifecycleException: java.io.FileNotFoundException: 无法打开 ServletContext 资源 [/WEB-INF/billboard-servlet.xml] ”。Dispather servlet 在默认位置找到上下文配置。
