使用Maven整合Spring+SpringMVC+Hibernate

使用Maven构建SpringMVC

项目演示代码地址：https://github.com/wchstrife/spring-mvc-demo

本篇文章主要参考了：http://www.cnblogs.com/xrog/p/6359706.html

1. 使用IDEA创建Maven项目

需要注意的就是选择模板的的时候要选择Web



2. 设置pom.xml将所需要的jar包导入

这里我们使用的是Maven自己帮我们管理的依赖，所以只需要更改pom.xml即可

pom.xml:

<?xml version="1.0" encoding="UTF-8"?>

<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">

完善工程目录

工程构建完成之后要手动创建一些目录，整体的目录结构如下



Spring MVC 配置文件

接下来是配置SpringMVC的配置文件

包括视图解析器、注解的驱动、扫描以及静态资源的映射

resources/META-INF/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="com.ssh" />

<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="viewClass" value="org.springframework.web.servlet.view.JstlView" />
<property name="prefix" value="views/" />      <!-- 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="/resources/js/" />
<mvc:resources mapping="/css/**" location="/resources/css/" />
<mvc:resources mapping="/img/**" location="/resources/img/" />

</beans>

5. web.xml

在这里需要配置Spring MVC 的DispatcherServlet

web.xml:

<?xml version="1.0" encoding="UTF-8"?>

<web-app version="2.4"
xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"> 
<welcome-file-list>
<welcome-file>/index.jsp</welcome-file>
</welcome-file-list>

<servlet>
<servlet-name>spring</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:META-INF/spring-mvc.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>

</servlet>
<servlet-mapping>
<servlet-name>spring</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>

</web-app>

到这里SpringMVC的配置就完成了

接下来配置Spring

整合Spring

这里只需要修改applicationContext.xml和web.xml即可

1. applicationContext.xml

这里只需要配置一下扫描即可

<?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"> 
<!-- 自动扫描 -->
<context:component-scan base-package="com.ssh">
<!-- 扫描时跳过 @Controller 注解的JAVA类（控制器） -->
<context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
</context:component-scan>

</beans>

web.xml

这里需要配置spring配置文件、监听器、字符集过滤

<?xml version="1.0" encoding="UTF-8"?>

<web-app version="2.4"
xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"> 
<welcome-file-list>
<welcome-file>/index.jsp</welcome-file>
</welcome-file-list>

<!--加载Spring的配置文件到上下文中去-->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
classpath:META-INF/applicationContext.xml
</param-value>
</context-param>

<!-- Spring监听器 -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

<!--  字符集过滤  -->
<filter>
<filter-name>encodingFilter</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>
<init-param>
<param-name>forceEncoding</param-name>
<param-value>true</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>encodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

<!-- spring MVC config start-->
<servlet>
<servlet-name>spring</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:META-INF/spring-mvc.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>

</servlet>
<servlet-mapping>
<servlet-name>spring</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
<!-- spring MVC config start-->

</web-app>

整合Hibernate

config.properties-Hibernate的数据库相关配置

这里需要配置对于数据库链接的相关信息，输入自己的账号密码即可

#database connection config
jdbc.driver = com.mysql.jdbc.Driver
jdbc.url = jdbc:mysql://localhost:3306/hibernate?useUnicode=true&characterEncoding=utf-8
jdbc.username = root
jdbc.password = root

#hibernate config
hibernate.dialect = org.hibernate.dialect.MySQLDialect
hibernate.show_sql = true
hibernate.format_sql = true

hibernate.hbm2ddl.auto = update

applicationContext.xml-Hibernate相关的配置

这里配置的是Hibernate相关的配置，注意要先把上面的配置文件引进进来

<?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"> 
<!--********************************************配置Spring***************************************-->
<!-- 自动扫描 -->

<!-- 扫描时跳过 @Controller 注解的JAVA类（控制器） -->
<context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
</context:component-scan>

<!--********************************************配置hibernate********************************************-->
<!--扫描配置文件(这里指向的是之前配置的那个config.properties)-->
<context:property-placeholder location="classpath:/config.properties" />

<!--配置数据源-->
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close">

<property name="jdbcUrl" value="${jdbc.url}" />     <!--数据库地址-->
<property name="user" value="${jdbc.username}" />   <!--用户名-->
<property name="password" value="${jdbc.password}" />   <!--密码-->

<property name="initialPoolSize" value="10" />      <!--初始化连接池内的数据库连接-->
<property name="maxIdleTime" value="20" />  <!--最大空闲时间-->
</bean>

<!--配置session工厂-->
<bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="packagesToScan" value="com.ssh.entity" />
<property name="hibernateProperties">
<props>
<prop key="hibernate.hbm2ddl.auto">${hibernate.hbm2ddl.auto}</prop> <!--hibernate根据实体自动生成数据库表-->

</property>
</bean>

<!-- 事物管理器配置  -->
<bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory" />
</bean>

</beans>
