本文详细介绍了一个结合SpringMVC和Hibernate技术的项目搭建过程，包括Maven项目的配置、依赖管理、目录结构的设计、配置文件的编写等内容。

废话

书接上文

我理解的框架整合就是将相应的依赖包引入工程，写好配置文件。

根据上一篇文章的手动创建maven project项目自动生成pom.xml文件

<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">
  <modelVersion>4.0.0</modelVersion>
  <groupId>com.zdh</groupId>
  <artifactId>springmvc_hibernate_jpa</artifactId>
  <packaging>war</packaging>
  <version>0.0.1-SNAPSHOT</version>
  <name>springmvc_hibernate_jpa Maven Webapp</name>
  <url>http://maven.apache.org</url>
  <dependencies>
    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <version>3.8.1</version>
      <scope>test</scope>
    </dependency>
  </dependencies>
  <build>
    <finalName>springmvc_hibernate_jpa</finalName>
  </build>
</project>

添加必要的目录结构

1.新建src/main/resources; src/test/resources; src/test/java三个目录文件夹

建立Java相应的包（路由服务和实体）

建立之后的结构如下图

新加的包结构解释

com.zdh.web.controller:控制器路由

com.zdh.domain.service:业务操作

com.zdh.domain.dao:和数据库相关操作

com.zdh.domain.entity:存放实体类

建立前端页面显示包

在src/main/webapp/WEB-INF下新建一个存放视图文件的文件夹,新建一个test.jsp 。得到如下视图:

导入相关依赖jar包

在pom.xml文件中导入相关的依赖配置最终得到如下的配置

添加相关配置文件

添加springMVC配置文件

在src/main/resources 目录结构下添加springMVC.xml文件并且配置启用spring mvc 的注解模式

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p"
	xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://www.springframework.org/schema/beans      
      http://www.springframework.org/schema/beans/spring-beans-3.0.xsd      
      http://www.springframework.org/schema/context      
      http://www.springframework.org/schema/context/spring-context-3.1.xsd      
      http://www.springframework.org/schema/mvc      
      http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">


	<!-- 支持注解 -->
	<mvc:annotation-driven />



	<!--自动装配DefaultAnnotationHandlerMapping和AnnotationMethodHandlerAdapter -->
	<mvc:default-servlet-handler />


	<!-- 设置自动扫描的路径,用于自动注入bean 这里的路径与自己的项目目录对应 -->
	<!-- 扫描controller路由控制器 -->
	<context:component-scan base-package="com.zdh.web.controller" />
	<context:component-scan
		base-package="com.zdh.domain.dao,com.zdh.domain.service" />



	<!-- 视图解析器 -->
	<bean id="viewResolver"
		class="org.springframework.web.servlet.view.InternalResourceViewResolver">
		<property name="viewClass"
			value="org.springframework.web.servlet.view.JstlView" />
		<property name="suffix" value=".jsp" />            <!-- 视图文件类型 -->
		<property name="prefix" value="/WEB-INF/views" />  <!-- 视图文件的文件夹路径 -->
	</bean>
</beans>

添加mysql配置文件

该配置文件主要是用来记录数据库的地址，用户名和密码等信息，在src/main/resources 下新建config.properties文件

#\u5C5E\u6027\u6587\u4EF6    
    
#Oracle \u7684\u914D\u7F6E    
#hibernate.dialect=org.hibernate.dialect.OracleDialect    
#driverClassName=oracle.jdbc.driver.OracleDriver    
#validationQuery=SELECT 1 FROM DUAL    
#jdbc_url=jdbc:oracle:thin:@localhost:1521:orcl    
#jdbc_username=    
#jdbc_password=    
    
#SQLServer \u7684\u914D\u7F6E    
#hibernate.dialect=org.hibernate.dialect.SQLServerDialect    
#driverClassName=net.sourceforge.jtds.jdbc.Driver    
#validationQuery=SELECT 1    
#jdbc_url=jdbc:jtds:sqlserver://127.0.0.1:1433/sy    
#jdbc_username=    
#jdbc_password=    
    
#Derby \u7684\u914D\u7F6E    
#hibernate.dialect=org.hibernate.dialect.DerbyDialect    
#driverClassName=org.apache.derby.jdbc.EmbeddedDriver    
#validationQuery=SELECT 1    
#jdbc_url=jdbc:derby:sy;create=true    
#jdbc_username=    
#jdbc_password=    
    
#MySQL \u7684\u914D\u7F6E    
hibernate.dialect=org.hibernate.dialect.MySQLDialect  
driverClassName=com.mysql.jdbc.Driver  
validationQuery=SELECT 1  
jdbc_url=jdbc\:mysql\://localhost\:3306/zdh?useUnicode\=true&characterEncoding\=utf-8  
jdbc_username=root  
jdbc_password=123456  
    
hibernate.hbm2ddl.auto=update  
hibernate.show_sql=true  
hibernate.format_sql=false  
    
sessionInfoName=sessionInfo   
    
uploadFieldName=filedata  
uploadFileMaxSize=20971520    
uploadFileExts=txt,rar,zip,doc,docx,xls,xlsx,jpg,jpeg,gif,png,swf,wmv,avi,wma,mp3,mid    
uploadDirectory=attached

config.properties文件将在hibernate配置文件中引用。

添加hibernate配置文件spring-hibernate.xml在路径src/main/resources下

添加web.xml配置在之前src/main/webapp中的web.xml中添加springMVC.xml，和spring-hibernate.xml的配置引用
