一、添加依赖

1、新建maven的web项目后，在pom.xml添加依赖信息，对应的groupId 、artifactId修改成自己新建的

<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/maven-v4_0_0.xsd">

2、个人使用的数据库是mysql，需要新建数据库moyapp

3、个人的项目信息结构

二、添加配置信息

1、在修改web.xml信息

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
         version="3.1">

  <!-- *** 初始化Spring容器开始 *** -->
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:spring.xml</param-value>
  </context-param>
  <!-- === 初始化Spring容器结束 === -->

  <!-- *** 初始化SpringMVC开始 *** -->
  <servlet>
    <servlet-name>springMVC</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath:spring-mvc.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>springMVC</servlet-name>
    <url-pattern>*.do</url-pattern>
  </servlet-mapping>
  <!-- === 初始化SpringMVC结束 === -->
</web-app>

View Code

2、在classpath下添加spring.xml文件，base-package属性值可以改成自己对应的项目基础包名

<?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:p="http://www.springframework.org/schema/p"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
       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">

    <!-- *** 导入外部配置文件开始 *** -->
    <context:property-placeholder location="classpath:db.properties"/>
    <!-- === 导入外部配置文件结束 === -->

    <context:component-scan base-package="com.moy"/>

    <import resource="spring-mvc.xml"/>
    <import resource="spring-dao.xml"/>
    <import resource="spring-tx.xml"/>
    <import resource="spring-task.xml"/>
</beans>

View Code

3、在classpath下添加spring-dao.xml，添加数据源配置，packagesToScan列出来的实体类包名可以换成自己的

<?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:p="http://www.springframework.org/schema/p"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
       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">

    <!-- *** dataSource start *** -->
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <property name="driverClass" value="${jdbc.driverClass}"/>
        <property name="jdbcUrl" value="${jdbc.url}"/>
        <property name="user" value="${jdbc.username}"/>
        <property name="password" value="${jdbc.password}"/>
    </bean>
    <!-- === dataSource end === -->

    <!-- *** sessionFactory start *** -->
    <bean id="sessionFactory"
          class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
        <property name="dataSource" ref="dataSource"></property>
        <property name="packagesToScan">
            <list>
                <value>com.moy.*.*.entity</value>
            </list>
        </property>
        <property name="hibernateProperties">
            <props>
                <prop key="hibernate.hbm2ddl.auto">update</prop>
                <prop key="hibernate.show_sql">true</prop>
                <prop key="hibernate.dialect">org.hibernate.dialect.MySQL5InnoDBDialect</prop>
            </props>
        </property>
    </bean>
    <!-- === sessionFactory end === -->
</beans>

View Code

4、（可选）在classpath下添加spring-task.xml，添加定时任务信息，spring3之后，可以更简单配置定时任务

<?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:p="http://www.springframework.org/schema/p"
       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:task="http://www.springframework.org/schema/task"
       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://www.springframework.org/schema/task
         http://www.springframework.org/schema/task/spring-task.xsd">

    <task:annotation-driven/>

    <task:scheduled-tasks>
        <task:scheduled ref="testTaskService" method="printCurrentTime" cron="* * * * * ?"/>
    </task:scheduled-tasks>

</beans>

View Code

5、在classpath下添加spring-tx.xml，添加事务配置信息，defaultPointcut的包名可以换成自己的

<?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:p="http://www.springframework.org/schema/p"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
         http://www.springframework.org/schema/beans/spring-beans.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">

    <!-- *** transactionManager start *** -->
    <bean id="transactionManager"
          class="org.springframework.orm.hibernate4.HibernateTransactionManager">
        <property name="sessionFactory" ref="sessionFactory"></property>
    </bean>
    <!-- === transactionManager end === -->

    <!-- === 配置事务增强处理Bean,指定事务管理器 end === -->

    <!-- *** 配置一个切入点 start *** -->
    <aop:config>
        <aop:pointcut id="defaultPointcut"
                      expression="
                            execution(* com.moy.*.*.dao.*Dao.*(..)) ||

        <aop:advisor advice-ref="txAdvice" pointcut-ref="defaultPointcut"/>
    </aop:config>
    <!-- === 配置一个切入点 end === -->

    <!-- *** 开启事务控制的注解支持(不建议使用) start *** -->
    <tx:annotation-driven transaction-manager="transactionManager"/>
    <!-- === 开启事务控制的注解支持 end === -->
</beans>

6、在classpath下添加spring-mvc.xml，配置spring-mvc信息

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

7、在classpath下添加db.properties ，配置数据库连接信息

jdbc.driverClass=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/moyapp?useSSL=false
jdbc.username=root
jdbc.password=123

View Code

8、（可选）在classpath下添加log4j.properties，配置日志信息

### 设置###
log4j.rootLogger=debug,stdout
### 输出信息到控制台 ###
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.out
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=[%-5p] %d{yyyy-MM-dd HH:mm:ss,SSS} method:%l%n%m%n
