一、新建maven项目

选中maven-aechetype-webapp

group Id一般为公司域；Artifact Id相当于项目名称；version不需要更改；Package不使用默认，手动清空

Finish

项目结构如图报错是因为没有加入servlet API 暂时不用管。

二、配置pom.xml

  1　　　　<properties>
  2          <!-- 文件拷贝编码 -->
  3         <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
  4         <!-- 输出编码 -->
  5         <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
  6         <!-- 编译编码 -->
  7         <maven.compiler.encoding>UTF-8</maven.compiler.encoding>

保存，Maven会自动联网去下载所有需要的jar包，只写jar的名字，不用记住，只要去Maven中央仓库去搜索，Maven中央仓库地址：http://search./完成之后，多了很多jar，并且都放到了配置的本地仓库中，以后要再使用相同版本的jar时候，就不需要联网下载了。

三、修改项目结构

因为构建的MSSH项目的结构并不是一个标准的Maven结构，我们需要手动新建几个Source Folder

这是标准的maven项目结构

src/main/java:存放java源文件

src/main/resources:存放项目配置文件，如spring.xml,hibernate.cfg.xml。。。

src/test/java:存放test的java文件

src/test/resources:存放test时候所需的配置文件

配置Source Folder的output folder

同步项目的jdk版本

设置web.xml的路径

further configuration available若没有出现可以先去掉dynamic web module的勾 apply之后再打上勾就会出现此选项设置路径为src/main/webapp

四、编写配置文件

web.xml

 1 <?xml version="1.0" encoding="UTF-8"?>
 2 <web-app xmlns:xsi="http://www./2001/XMLSchema-instance" xmlns="http://java./xml/ns/javaee" xsi:schemaLocation="http://java./xml/ns/javaee http://java./xml/ns/javaee/web-app_3_0.xsd" version="3.0">
 3   <display-name></display-name>
 4   
 5   <!-- Spring ApplicationContext配置文件的路径,可使用通配符,多个路径用,号分隔 此参数用于后面的Spring Context 
 6         Loader -->
 7   <context-param>
 8     <param-name>contextConfigLocation</param-name>
 9     <param-value>classpath:spring.xml,classpath:spring-hibernate.xml</param-value>
10   </context-param>
11   
12   <!-- spring 监听器 -->
13   <listener>
14     <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
15   </listener>
16   
17   <!-- Filter 定义 -->
18   <!-- Character Encoding filter -->
19   <filter>
20     <filter-name>encodingFilter</filter-name>
21     <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
22     <init-param>
23       <param-name>encoding</param-name>
24       <param-value>UTF-8</param-value>
25     </init-param>
26   </filter>
27   <filter-mapping>
28     <filter-name>encodingFilter</filter-name>
29     <url-pattern>/*</url-pattern>
30   </filter-mapping>
31   <!--Hibernate的session丢失解决方法 -->
32   <filter>
33     <filter-name>openSessionInView</filter-name>
34     <filter-class>org.springframework.orm.hibernate4.support.OpenSessionInViewFilter</filter-class>
35   </filter>
36   <filter-mapping>
37     <filter-name>openSessionInView</filter-name>
38     <url-pattern>/*</url-pattern>
39   </filter-mapping>
40   
41   <!-- struts2 filter -->
42   <filter>
43     <filter-name>struts2</filter-name>
44     <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
45   </filter>
46   <filter-mapping>
47     <filter-name>struts2</filter-name>
48     <url-pattern>/*</url-pattern>
49   </filter-mapping>
50   
51   
52   <welcome-file-list>
53     <welcome-file>login.jsp</welcome-file>
54   </welcome-file-list>
55 </web-app>

database.properties

username=root
password=root


hibernate.hbm2ddl.auto=update
hibernate.show_sql=true
hibernate.format_sql=false

spring.xml

扫描com.shi包下的文件

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www./schema/beans"
    xmlns:xsi="http://www./2001/XMLSchema-instance" xmlns:context="http://www./schema/context"

    http://www./schema/context/spring-context-3.0.xsd
    ">

    <!-- 引入属性文件 -->
    <context:property-placeholder location="classpath:database.properties" />

    <!-- 自动扫描dao和service包(自动注入) -->
    <context:component-scan base-package="com.shi" />
    
</beans>

spring-hibernate.xml

    <!-- 使用C3P0数据源，MySQL数据库 -->
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"
        destroy-method="close">
        <!-- MySQL5 -->
        <property name="driverClass" value="${driverClassName}"></property>

        <property name="sessionFactory" ref="sessionFactory"></property>
    </bean>
    <tx:annotation-driven transaction-manager="txManager" />


</beans>

struts.xml

使用零配置，扫描com.shi包下的文件

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN" "http://struts./dtds/struts-2.3.dtd">
<struts>
    <!-- 将Action交给spring容器管理 -->
    <constant name="struts.objectFactory" value="spring" />
    
    <!-- 零配置 -->
    <constant name="struts.convention.package.locators" value="shi" />
    <constant name="struts.convention.package.locators.basePackage" value="com" />
    
    <!-- 模式为开发模式，修改xml配置文件会自动加载，项目交付的时候设置为false,以免影响性能 -->
    <constant name="struts.devMode" value="true" />
    <constant name="struts.configuration.xml.reload" value="true" />
    <!-- 字符集编码 -->
    <constant name="struts.i18n.encoding" value="utf-8" />
    <package name="defaultPackage" namespace="/" extends="struts-default">

    </package>
</struts>

五、使用

 User

 UserDao

 UserManager

 UserAction
