1、SSH框架整合

1、建立项目

2、导入SSHjar包

http://pan.baidu.com/s/1hsELr04

3、引入web.xml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"
    id="WebApp_ID" version="2.5">
    <display-name>crm</display-name>

    <!-- 配置Spring框架整合WEB的监听器 -->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:applicationContext.xml</param-value>
    </context-param>

 <!-- 解决延迟加载的问题也注释掉 -->

　　
    <!-- 解决延迟加载的问题 -->
    <filter>
        <filter-name>OpenSessionInViewFilter</filter-name>
        <filter-class>org.springframework.orm.hibernate5.support.OpenSessionInViewFilter</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>OpenSessionInViewFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
    
    
    <!-- 配置Struts2框架的核心的过滤器 -->
    <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>
    </filter-mapping>
    
    <!-- 程序出现了500的异常，跳转到error.jsp的页面 -->
    <error-page>
        <error-code>500</error-code>
        <location>/jsp/error.jsp</location>
    </error-page>
    
    <welcome-file-list>
        <welcome-file>login.jsp</welcome-file>
    </welcome-file-list>
</web-app>

4、导入struts.xml、log4j.properties、applicationContext.xml

<!--struts.xml基本上不需要变化,模仿写配置即可-->
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
    "http://struts.apache.org/dtds/struts-2.3.dtd">
<struts>
    
    <!-- 先配置包结构 -->
    <package name="crm" extends="struts-default" namespace="/">
        
        <!-- 配置全局的结果页面 -->
        <global-results>
            <result name="login" type="redirect">/login.jsp</result>
        </global-results>
        
        <!-- 配置客户的Action，如果Action由Spring框架来管理，class标签上只需要编写ID值就OK -->
        <action name="customer_*" class="customerAction" method="{1}">
            <result name="page">/jsp/customer/list.jsp</result>
        </action>
        
        <!-- 配置用户的模块 -->
        <action name="user_*" class="userAction" method="{1}">
            <result name="loginOK" type="redirect">/index.jsp</result>
        </action>
        
    </package>
    
</struts>

###log4j.properties基本上不需要变化

### direct log messages to stdout ###
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.err
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n

### direct messages to file mylog.log ###
log4j.appender.file=org.apache.log4j.FileAppender
log4j.appender.file.File=c\:mylog.log
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n

### set log levels - for more verbose logging change 'info' to 'debug' ###

log4j.rootLogger=info, stdout
