一、新建maven项目，配置ssh框架pom的最低支持

1、新建一个maven项目 

2、添加一个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"  xmlns:web = "http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
    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 >limanman</ display-name >


</ web-app >

3、基本ssh框架pom.xml配置

< project  xmlns = "http://maven.apache.org/POM/4.0.0"  xmlns:xsi = "http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation = "http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd" >

        < artifactId >spring-web</ artifactId >
        < version >3.1.1.RELEASE</ version >
    </ dependency >

  </ dependencies >
</ project >

二、maven webproject 整合struts2

1、web.xml 加入中心拦截器配置

< filter >
        < filter-name >struts2</ filter-name >
        < filter-class >org.apache.struts2.dispatcher.FilterDispatcher</ filter-class >
    </ filter >

    < filter-mapping >
        < filter-name >struts2</ filter-name >
        < url-pattern >/*</ url-pattern >
    </ filter-mapping >

2、加入log4j.xml

<? xml  version = "1.0"  encoding = "UTF-8" ?>
<! DOCTYPE  log4j:configuration PUBLIC "-//Apache//DTD Log4j 1.2//EN"
                                    "http://logging.apache.org/log4j/docs/api/org/apache/log4j/xml/log4j.dtd">
< log4j:configuration >
    < appender  class = "org.apache.log4j.ConsoleAppender"  name = "RootConsoleAppender" >
        < param  name = "Threshold"  value = "debug"  />
        < layout  class = "org.apache.log4j.PatternLayout" >
            < param  name = "ConversionPattern"  value = "%d{ABSOLUTE} %-5p [%c{1}] %m%n"  />
        </ layout >
    </ appender >

    < category  name = "com.fengshu.limanman.winssage" >
        < priority  value = "debug"  />
    </ category >

    < category  name = "org.springframework" >
        < priority  value = "warn"  />
    </ category >

    < category  name = "org.hibernate" >
        < priority  value = "warn"  />
    </ category >
    < category  name = "org.dbunit" >
        < priority  value = "warn"  />
    </ category >

    < category  name = "com.mchange.v2" >
        < priority  value = "warn"  />
    </ category >
    < category  name = "org.apache" >
        < priority  value = "warn"  />
    </ category >
    < category  name = "org.logicalcobwebs" >
        < priority  value = "warn"  />
    </ category >
    < category  name = "com.opensymphony" >
        < priority  value = "warn"  />
    </ category >

    < root >
        < level  value = "info"  />
        < appender-ref  ref = "RootConsoleAppender"  />
    </ root >

</ log4j:configuration >

3、引入struts2.xml 根据约定由于配置原则，将此配置文件放在更目录即可

<? xml  version = "1.0"  encoding = "UTF-8"  ?>
<! DOCTYPE  struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
    "http://struts.apache.org/dtds/struts-2.0.dtd">
< struts >
    < package  name = "fengshu"  namespace = "/user"  extends = "struts-default" >

        <!--<action name="user"
            class="com.fengshu.limanman.winssage.controller.LoginController">
            <result name="success">/pages/index.jsp</result>
        </action>-->
    </ package >
</ struts >

4、建一个测试jsp在webapp/pages/index.jsp

<%@ page language="java" contentType="text/html; charset=utf-8"
    pageEncoding="utf-8"%>
<! DOCTYPE  html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
< html >
< head >
< meta  http-equiv = "Content-Type"  content = "text/html; charset=utf-8" >
< title >Insert title here</ title >
</ head >
< body >hello limanman
</ body >
</ html >

5、写一个controller

package  com.fengshu.limanman.controller;

import  org.apache.log4j.Logger;

import  com.opensymphony.xwork2.ActionSupport;

public  class  LoginController  extends  ActionSupport {
    private  static  final  long  serialVersionUID = 1L;
    private  Logger log=Logger.getLogger( this .getClass());

    public  String  login() {
        log.info( "hello  i am limanman" );
        return  "succerss" ;

    }

}

6、配置struts2.xml

<? xml  version = "1.0"  encoding = "UTF-8"  ?>
<! DOCTYPE  struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
    "http://struts.apache.org/dtds/struts-2.0.dtd">
< struts >
    < package  name = "fengshu"  namespace = "/"  extends = "struts-default" >

        < action  name = "user"  class = "com.fengshu.limanman.controller.LoginController" >
            < result  name = "success" >/pages/index.jsp</ result >
        </ action >
    </ package >
</ struts >

7、暂时注释掉pom.xml中的struts2-spring-plugin

因为还没有整合spring，如果加入struts2-spring-plugin将会报空指针异常，整合spring后需要加入此jar包，下面将不再提及。

 

8、配置jetty运行环境，开发的时候我们一般使用jetty服务器，而不用tomcat

在pom.xml中加入jetty插件，并且配置根目录目录

< build >
        < plugins >
            <!-- 配置加入jetty服务器，开发时我们一般使用jetty服务器 -->
            < plugin
