BOS物流项目04———bos-web模块配置之web.xml

这个文件的配置，主要就是完成 SSH 的基本配置

一、web.xml 中 hibernate 配置

hibernate 主要就是配置扩大 Session 作用范围，添加如下代码

    <!--配置过滤器,解决hibernate延迟加载的问题-->
    <filter>
        <filter-name>openSessionInView</filter-name>
        <filter-class>org.springframework.orm.hibernate5.support.OpenSessionInViewFilter</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>openSessionInView</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

二、web.xml 中 struts2配置

struts2配置，主要就是配置核心过滤器

    <!-- 配置struts2的核心过滤器 -->
    <filter>
        <filter-name>struts2</filter-name>
        <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>struts2</filter-name>
        <url-pattern>/*</url-pattern>
        <dispatcher>REQUEST</dispatcher>
        <dispatcher>FORWARD</dispatcher>
    </filter-mapping>

这个配置有两个配置很奇特，这个配置是为了内部的请求、转发能让struts2拦截到。

        <dispatcher>REQUEST</dispatcher>
        <dispatcher>FORWARD</dispatcher>

三、web.xml 中 Spring配置

spring的配置，其实主要就是配置，applicationContext.xml 文件的位置，和监听器

    <!-- 通过上下文参数指定spring配置文件位置 -->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:applicationContext.xml</param-value>
    </context-param>

    <!-- 配置spring框架的监听器 -->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

四、首页配置

    <welcome-file-list>
        <welcome-file>index.html</welcome-file>
        <welcome-file>index.htm</welcome-file>
        <welcome-file>index.jsp</welcome-file>
        <welcome-file>default.html</welcome-file>
        <welcome-file>default.htm</welcome-file>
        <welcome-file>default.jsp</welcome-file>
    </welcome-file-list>

五、文件源码

5.1 web.xml

<?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">


<display-name>Archetype Created Web Application</display-name>


    <!-- 通过上下文参数指定spring配置文件位置 -->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:applicationContext.xml</param-value>
    </context-param>

    <!-- 配置spring框架的监听器 -->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

    <!--配置过滤器,解决hibernate延迟加载的问题-->
    <filter>
        <filter-name>openSessionInView</filter-name>
        <filter-class>org.springframework.orm.hibernate5.support.OpenSessionInViewFilter</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>openSessionInView</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

    <!-- 配置struts2的核心过滤器 -->
    <filter>
        <filter-name>struts2</filter-name>
        <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>struts2</filter-name>
        <url-pattern>/*</url-pattern>
        <dispatcher>REQUEST</dispatcher>
        <dispatcher>FORWARD</dispatcher>
    </filter-mapping>



    <welcome-file-list>
        <welcome-file>index.html</welcome-file>
        <welcome-file>index.htm</welcome-file>
        <welcome-file>index.jsp</welcome-file>
        <welcome-file>default.html</welcome-file>
        <welcome-file>default.htm</welcome-file>
        <welcome-file>default.jsp</welcome-file>
    </welcome-file-list>

</web-app>
