本博客内容是sssp（spring、spingMVC、springData、jpa）项目的整合过程，希望此内容能够帮到有需要的人。
环境介绍：eclipse、jdk1.8、spring4.2.5
一、在eclipse中新建dynamic web project。
二、加入spring
加入spring必须的jar包（其中包含了spring和springMVC所需要的jar包）：
com.springsource.net.sf.cglib-2.2.0.jar
com.springsource.org.aopalliance-1.0.0.jar
com.springsource.org.aspectj.weaver-1.6.8.RELEASE.jar
commons-logging-1.2.jar
spring-aop-4.2.5.RELEASE.jar
spring-aspects-4.2.5.RELEASE.jar
spring-beans-4.2.5.RELEASE.jar
spring-context-4.2.5.RELEASE.jar
spring-core-4.2.5.RELEASE.jar
spring-expression-4.2.5.RELEASE.jar
spring-jdbc-4.2.5.RELEASE.jar
spring-orm-4.2.5.RELEASE.jar
spring-tx-4.2.5.RELEASE.jar
spring-web-4.2.5.RELEASE.jar
spring-webmvc-4.2.5.RELEASE.jar在classpath下加入sping的配置文件applicationContext.xml

- 在web.xml中配置启动 IOC 容器的 Listener
<!-- 配置启动 IOC 容器的 Listener -->

<param-value>classpath:applicationContext.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>二、加入springMVC
- 在WEB-INF下加入springMVC的配置文件springDispatcherServlet-servlet.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/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd
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-4.0.xsd">
<!-- 配置自动扫描的包 -->
<context:component-scan base-package="com.scry.sssp" use-default-filters="false">
<context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
<context:include-filter type="annotation" expression="org.springframework.web.bind.annotation.ControllerAdvice"/>
</context:component-scan>
<!-- 配置视图解析器 -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/views/"></property>
<property name="suffix" value=".jsp"></property>
</bean>
<mvc:default-servlet-handler/>
<mvc:annotation-driven></mvc:annotation-driven>
</beans>
- 在web.xml中配置 SpringMVC 的 DispatcherServlet
<!-- 配置 SpringMVC 的 DispatcherServlet -->
<servlet>
<servlet-name>springDispatcherServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<!-- 配置DispatcherServlet的一个初始化参数：配置SpringMVc配置文件的位置和名称 -->
<!--
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:springmvc.xml</param-value>
</init-param>
-->
<!-- 如果不配置文件的路径，默认读取 /WEB-INF/<servlet-name>-servlet.xml 例如：/WEB-INF/springDispatcherServlet-servlet.xml -->
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>springDispatcherServlet</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
三、加入JPA
加入JPA所需的jar包，此jar包多数可在hibernate的jar包中找到
antlr-2.7.7.jar
dom4j-1.6.1.jar
hibernate-commons-annotations-4.0.5.Final.jar
hibernate-core-4.3.11.Final.jar
hibernate-jpa-2.1-api-1.0.0.Final.jar
jandex-1.1.0.Final.jar
javassist-3.18.1-GA.jar
jboss-logging-3.1.3.GA.jar
jboss-logging-annotations-1.2.0.Beta1.jar
jboss-transaction-api_1.2_spec-1.0.0.Final.jar
hibernate-entitymanager-4.3.11.Final.jar
c3p0-0.9.2.1.jar
hibernate-c3p0-4.3.11.Final.jar
mchange-commons-java-0.2.3.4.jar
ehcache-core-2.4.3.jar
hibernate-ehcache-4.3.11.Final.jar
slf4j-api-1.6.1.jar
mysql-connector-java-5.1.7-bin.jar在applicationContext.xml中配置JPA相关信息（具体代码在前面的applicationContext.xml中）
四、加入springData
加入jar包
spring-data-jpa-1.4.2.RELEASE.jar
spring-data-commons-1.6.2.RELEASE.jar在applicationContext.xml中配置springData相关信息（具体代码在前面的applicationContext.xml中）
到此整个整合过程配置结束。
五、项目结构
可以建立单元测试类SSSPTest.java进行测试
