在web.xml中提供Spring配置文件的正確方法

Question

在我的示例SPring項目中，我正在使用以下web.xml，我認為它無法正確使用
root-context.xml
servlet-context.xml
security-context.xml

我應該如何更改它以正確提供這三個配置文件？

<?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

典型的過濾器映射位於servlet映射之后（ 調整web.xml偵聽器，過濾器和servlet ）

另一件事看起來很奇怪：您寫道您有一個：

• root-context.xml
• servlet-context.xml
• security-context.xml

當然，名稱“ root-context.xml”不是標准化的，但是我希望他是包含服務，DAO，數據庫連接但不包含Web控制器內容的spring配置文件。 如果是這樣，則應使用由ContextLoaderListener創建並由context-param contextConfigLocation配置的“內部應用程序上下文”加載root-context.xml 。 security-context.xml也必須由ContextLoaderListener加載，因此，如果root-context.xml沒有security-context.xml導入，則必須在contextConfigLocation它們都進行配置

  <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>

也許您應該看看這個問題： ContextLoaderListener與否？ -問題和可接受的答案稍微說明了這兩種情況的工作原理。
