1、创建maven webapp项目

2、书写pom.xml文件

  <!-- 到这结束 -->

3、书写spring-mvc.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans-4.1.xsd
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context-4.1.xsd
        http://www.springframework.org/schema/mvc
        http://www.springframework.org/schema/mvc/spring-mvc-4.1.xsd">

    <!-- 启动注解驱动的spring MVC功能,注册请求url和注解POJO类方法的映射-->
    <mvc:annotation-driven />
    <!-- 对模型视图名称的解析,在请求时模型视图名称添加前后缀 -->
    <context:component-scan base-package="cn.x5456" />

    <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="viewClass" value="org.springframework.web.servlet.view.JstlView" />
        <property name="prefix" value="/WEB-INF/jsp/system/" />      <!-- 前缀 -->
        <property name="suffix" value=".jsp" />   <!-- 后缀 -->
    </bean>

    <!--这里是对静态资源的映射-->
    <!--<mvc:resources mapping="/js/**" location="/js/" />-->
    <!--<mvc:resources mapping="/css/**" location="/css/" />-->
    <!--<mvc:resources mapping="/img/**" location="/img/" />-->

</beans>

4、书写applicationContext.xml

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
       xmlns:jaxws="http://cxf.apache.org/jaxws"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
	http://www.springframework.org/schema/beans/spring-beans.xsd
	http://www.springframework.org/schema/context
	http://www.springframework.org/schema/context/spring-context.xsd
	http://www.springframework.org/schema/aop
	http://www.springframework.org/schema/aop/spring-aop.xsd
	http://www.springframework.org/schema/tx
	http://www.springframework.org/schema/tx/spring-tx.xsd http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd">


    <!-- *************************配置连接池************************* -->

    <!--1.设置读取db.properties文件-->
    <context:property-placeholder location="classpath:config.properties"/>

    <!--2.设置连接池-->
    <bean name="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <property name="DriverClass" value="${jdbc.driverClass}"/>
        <property name="JdbcUrl" value="${jdbc.jdbcUrl}"/>
        <property name="User" value="${jdbc.user}"/>
        <property name="Password" value="${jdbc.password}"/>
    </bean>


    <!--配置SessionFactory到容器中-->
    <bean name="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">

        <!--3.将连接池注入sessionFactory-->
        <property name="dataSource" ref="dataSource"/>

        <!-- 配置hibernate基本信息 -->
        <property name="hibernateProperties">
            <props>
                <!--方言-->
                <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>

                <!--  可选配置 打印SQL语句，缩进，自动建表 -->
                <prop key="hibernate.show_sql">true</prop>
                <prop key="hibernate.format_sql">true</prop>
                <prop key="hibernate.hbm2ddl.auto">update</prop>
            </props>
        </property>
        <!--引入orm元数据,指定orm元数据所在的包路径,spring会自动读取包中的所有配置 -->
        <!--<property name="mappingDirectoryLocations" value="classpath:cn/x5456/entity/" />-->
        <property name="mappingLocations">
            <list>
                <value>classpath:cn/x5456/domain/*.xml</value>
                <!--maven工程将bos-domain打成一个jar包，搜索package找不到；所以要用类路径来找-->
            </list>
        </property>
    </bean>


    <!-- *************************开启注解事务************************* -->
    <!-- 核心事务管理器 -->
    <bean name="transactionManager" class="org.springframework.orm.hibernate5.HibernateTransactionManager">
        <property name="sessionFactory" ref="sessionFactory"/>
    </bean>

    <!--将autowire...注解对象加入spring容器；但由于 <context:component-scan base-package="cn.x5456.bos"/>这句也会将其加入容器，所以可以不用写-->
    <!--<context:annotation-config/>-->

    <!--注：使用扫描事物，一定要开spring组件扫描-->
    <context:component-scan base-package="cn.x5456"/>

    <!--扫描事物-->
    <tx:annotation-driven transaction-manager="transactionManager"/>

</beans>

config.properties文件

jdbc.jdbcUrl=jdbc:mysql:///oa
jdbc.driverClass=com.mysql.jdbc.Driver
jdbc.user=root
jdbc.password=5456

5、书写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"
         version="2.5">


  <!-- 解决post乱码 -->
  <filter>
    <filter-name>CharacterEncodingFilter</filter-name>
    <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
    <init-param>
      <param-name>encoding</param-name>
      <param-value>utf-8</param-value>
    </init-param>
  </filter>
  <filter-mapping>
    <filter-name>CharacterEncodingFilter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>


  <!-- springmvc的前端控制器 -->
  <servlet>
    <servlet-name>oa</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <!-- contextConfigLocation不是必须的， 如果不配置contextConfigLocation， springmvc的配置文件默认在：WEB-INF/servlet的name+"-servlet.xml" -->
    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath:spring/*.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>oa</servlet-name>
    <url-pattern>*.action</url-pattern>
  </servlet-mapping>
</web-app>
