在web.xml

Question

在我的示例SPring项目中，我正在使用以下web.xml， 我认为它没有正确使用
根的context.xml
servlet的context.xml中
security-context.xml

如何更改它以提供这三个配置文件 正确吗？

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" version="2.5">
  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>
            /WEB-INF/spring/appServlet/app-security-context.xml
        </param-value>
  </context-param>
  <filter>
    <filter-name>springSecurityFilterChain</filter-name>
    <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
  </filter>
  <filter-mapping>
    <filter-name>springSecurityFilterChain</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>

  <servlet>
    <servlet-name>appServlet</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>
                /WEB-INF/spring/appServlet/servlet-context.xml
            </param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>appServlet</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>
</web-app>

Answer 1

典型的filter-mapping位于servlet映射（Adjusting web.xml listeners, filters and servlets）

之后

另一件事看起来很奇怪：你写道：你有一个：

• 根context.xml中
• servlet的context.xml中
• security-context.xml

当然名称＆＃34; root-context.xml＆＃34;是不标准化的，但我希望他是包含服务，DAO，db连接但不包含web控制器内容的spring配置文件。如果是这样，那么您应该使用＆＃34;内部应用程序上下文加载root-context.xml＆＃34;由ContextLoaderListener创建并由context-param contextConfigLocation配置。 security-context.xml也必须加载ContextLoaderListener，因此如果security-context.xml中的root-context.xml没有导入，那么您必须在contextConfigLocation中配置它们

  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>
            /WEB-INF/spring/appServlet/root-context.xml,
            /WEB-INF/spring/appServlet/app-security-context.xml
        </param-value>
  </context-param>

也许你应该看看这个问题：ContextLoaderListener or not? - 接受的答案的问题解释了两个背景如何运作。
