Spring+SpringMVC+Hibernate

本框架为基于全注解的SpringMVC+Spring4.2+hibernate4.3

开发工具:    myEclipse.

整个工程含完整jar包，可在这里下载： http://www.demodashi.com/demo/10217.html

整体目录结构如下图：

最近在鼓捣SpringMVC框架，现将成果都记录下来，免得前学后忘。之前用的框架一直是S2SH，一直苦于要配置一堆的配置文件，自从接触SpringMVC，发现这才是我一直想要的框架，基于全注解，开发过程中零配置，实在快哉。此教程非常适合零基础的人学习回归正题，基于全注解驱动的SpringMVC+Spring4.2+hibernate4.3框架搭建（整合）过程如下，：

开发工具为myEclipse

第一步：新建一个web项目

第二步：加入所需的jar包

第三步：接下来我们开始配置SpringMVC容器

为了分工明确，我们将SpringMVC的配置单独写在spring-servlet.xml里，Spring的配置写在spring-common.xml（事务、数据源、sessionFactory等等）里。

spring-common.xml和spring-servlet.xml先加入如下schemal

 <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:tx="http://www.springframework.org/schema/tx"
     xmlns:aop="http://www.springframework.org/schema/aop" xmlns:mvc="http://www.springframework.org/schema/mvc"
     xmlns:task="http://www.springframework.org/schema/task" xmlns:cache="http://www.springframework.org/schema/cache"
     xmlns:util="http://www.springframework.org/schema/util"
     xmlns:websocket="http://www.springframework.org/schema/websocket"
     xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.1.xsd
                     http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.1.xsd
                     http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-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
                     http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task-4.1.xsd
                     http://www.springframework.org/schema/cache http://www.springframework.org/schema/cache/spring-cache-4.1.xsd
                     http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.1.xsd">

然后spring容器的配置先放下，先来配置springMVC（spring-servlet.xml）的配置

在schemal的结尾处加入这一句：default-autowire="byName" ，依赖注入将根据name自动装配。

接下来启动注解驱动的SpringMVC功能：

 <mvc:annotation-driven />

扫描注解包（在SpringMVC的容器里，只扫描Controller注解就行了）

 <context:component-scan base-package="com.mvc.rest"
         use-default-filters="false">
         <context:include-filter type="annotation"
             expression="org.springframework.stereotype.Controller" />
   context:component-scan>

use-default-filters默认为true，默认会扫描@Component、@Controller、@Repository、@Service的注解，在这里只扫描@Controller注解是因为，SpringMVC的容器没有事务的能力，所以扫描@Repository、@Service的注解只能放在Spring的容器。也正因为如此，事务的配置要写在Spring的容器。

然后是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（前缀是从控制器里返回的视图的父目录，此处配置的是让容器在WEB-INF/view/下找寻对应的视图；后缀是给视图名称追加后缀名，此处配置的是jsp后缀）

 <bean  class="org.springframework.web.servlet.view.InternalResourceViewResolver"  p:prefix="/WEB-INF/view/" p:suffix=".jsp" />

配置CommonsMultpartResolver，上传文件的时候要用到CommonsMultpartResolver，maxUploadSize设置上传文件的大小限制，上传文件必须先配置此解析器。

 <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
      <property name="maxUploadSize" value="10485760" />
 bean>

配置login视图解析，在登录拦截器里，校验未登录的话，要跳转到登录页面，然后由于login页面放在WEB-INF目录下，所以设置跳转到login.jsp会跳转不过去，在此处设置如下，在返回此view-name的地方，容器便不会当作Controller的路径，当作视图的路径跳转，在拦截器里便可以跳转到login页面（此配置告诉容器，这不是一个controller的方法的路径，而是一个视图的名称，请当作视图处理）。

 <mvc:view-controller path="/" view-name="login" />

拦截器的配置也是放在SpringMVC的容器里，拦截器以后的文章里再详细解说。

到此spring-servlet.xml的配置就告一段落了，spring-servlet.xml的全文如下：

 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:tx="http://www.springframework.org/schema/tx"
     xmlns:aop="http://www.springframework.org/schema/aop" xmlns:mvc="http://www.springframework.org/schema/mvc"
     xmlns:task="http://www.springframework.org/schema/task" xmlns:cache="http://www.springframework.org/schema/cache"
     xmlns:util="http://www.springframework.org/schema/util"
     xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.1.xsd
         http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.1.xsd
         http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-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

         http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.1.xsd"
     default-autowire="byName">
     <mvc:annotation-driven />

     <context:component-scan base-package="com.mvc.rest" use-default-filters="false">
       <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller" />
     context:component-scan>

     <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"
         p:prefix="/WEB-INF/view/" p:suffix=".jsp" />
     <mvc:view-controller path="/" view-name="login" />
     <bean id="multipartResolver"
         class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
         <property name="maxUploadSize" value="10485760" />
     bean>

 <property name="packagesToScan">
   <list>
     <value>com.mvc.rest.entityvalue>
  list>
 property>
  bean>

packagesToScan扫描我们的hibernate实体文件。

最后配置事务

 <bean id="txManager"
         class="org.springframework.orm.hibernate4.HibernateTransactionManager">
         <property name="sessionFactory" ref="sessionFactory" />
     bean>
     <tx:advice id="txAdvice" transaction-manager="txManager">
         <tx:attributes>
             <tx:method name="save*" propagation="REQUIRED" />
             <tx:method name="add*" propagation="REQUIRED" />
             <tx:method name="edit*" propagation="REQUIRED" />
             <tx:method name="update*" propagation="REQUIRED" />
             <tx:method name="delete*" propagation="REQUIRED" />
             <tx:method name="register*" propagation="REQUIRED" />
             <tx:method name="all" propagation="REQUIRED" />
             <tx:method name="changePassword*" propagation="REQUIRED" />
             <tx:method name="restPassword*" propagation="REQUIRED" />
             <tx:method name="authorize*" propagation="REQUIRED" />
             <tx:method name="send*" propagation="REQUIRED" />
             <tx:method name="init*" propagation="REQUIRED" />

         tx:attributes>
     tx:advice>
     <aop:config>
         <aop:pointcut id="serviceOperation"
             expression="execution(* com.mvc.rest.service.impl.*.*(..))" />
         <aop:advisor advice-ref="txAdvice" pointcut-ref="serviceOperation" />
 aop:config>

完整的spring-common.xml的配置如下：

到此，基于全注解的SpringMVC+Spring4.2+hibernate4.3框架搭建大功告成。
