Spring SpringMVC Hibernate整合时的一些问题

目录结构为：

（1）springMVC + spring: exclude,include

SpringMVC 专注于Controller，其他的放到Spring中

SpringMVC配置为：

<context:component-scan base-package="com.controller"><context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/><context:exclude-filter type="annotation" expression="org.springframework.stereotype.Service"/><context:exclude-filter type="annotation" expression="org.springframework.stereotype.Repository"/></context:component-scan>

Spring配置为：

<context:component-scan base-package="com"><context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/></context:component-scan>

（2）c3p0数据源和普通的jdbc 配置中的name是有区别的，还是不一样的

（3）Hibernate注解方式与spring整合时可能会报找不到hibernate.cfg.xml的错误，这时在归Hibernate管理的DAO中获取Session的方式要做一些修改，因为交给Spring管理了，所以更改如下：

@Repositorypublic class PersonDao {@Autowired SessionFactory sessionFactory;public Session getSession(){return sessionFactory.openSession();// return sessionFactory.getCurrentSession();}}

Spring的ApplicationContext配置文件相应的定义SessionFactory的部分为：

<!-- 配置Hibernate的相关的属性 --><bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"><property name="dataSource" ref="dataSource"></property><property name="hibernateProperties"><props><prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop><prop key="hibernate.show_sql">true</prop><prop key="hibernate.format_sql">true</prop><prop key="hibernate.hbm2ddl.auto">update</prop><prop key="hibernate.current_session_context_class">org.springframework.orm.hibernate4.SpringSessionContext</prop></props></property><property name="packagesToScan"><list><value>com.entity</value></list></property></bean>

最后，贴上ApplicationContext.xml和springmvc-servlet.xml，Web.xml的全部配置信息：

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>    <!-- 加载applicationContext.xml -->  <context-param>  <param-name>contextConfigLocation</param-name>  <param-value>classpath:applicationContext.xml</param-value>  </context-param>          <listener>  <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>  </listener>    <!-- 运行的时候才会访问DispatcherServlet，如果想改变这种状态，就用load-on-startup -->  <servlet>  <servlet-name>springmvc</servlet-name>  <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>  <load-on-startup>1</load-on-startup>  </servlet>    <servlet-mapping>  <servlet-name>springmvc</servlet-name>  <url-pattern>*.html</url-pattern>  </servlet-mapping>  </web-app>

ApplicationContext.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: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"><!-- 引入外部的属性文件 --><context:property-placeholder location="classpath:jdbc.properties"/><bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"><property name="driverClassName" value="${jdbc.driverClass}"></property><property name="url" value="${jdbc.url}"></property><property name="username" value="${jdbc.username}"></property><property name="password" value="${jdbc.password}"></property></bean><context:component-scan base-package="com"><context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/></context:component-scan><!-- 配置业务层类 --><bean id="personService" class="com.service.PersonService"><property name="personDao" ref="personDao"></property></bean><!-- 配置DAO的类，直接注入连接池，可自动创建jdbc模板 --><bean id="personDao" class="com.dao.PersonDao"></bean><!-- 配置Hibernate的相关的属性 --><bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"><property name="dataSource" ref="dataSource"></property><property name="hibernateProperties"><props><prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop><prop key="hibernate.show_sql">true</prop><prop key="hibernate.format_sql">true</prop><prop key="hibernate.hbm2ddl.auto">update</prop><prop key="hibernate.current_session_context_class">org.springframework.orm.hibernate4.SpringSessionContext</prop></props></property><property name="packagesToScan"><list><value>com.entity</value></list></property></bean><!-- 配置事务管理器 --><bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager"><property name="sessionFactory" ref="sessionFactory"></property></bean><!-- 开启注解事务 --><tx:annotation-driven transaction-manager="transactionManager"/></beans>

springmvc-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:aop="http://www.springframework.org/schema/aop"xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx"xmlns:p="http://www.springframework.org/schema/p"xmlns:mvc="http://www.springframework.org/schema/mvc"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-3.0.xsd                         http://www.springframework.org/schema/tx                        http://www.springframework.org/schema/tx/spring-tx-3.0.xsd                        http://www.springframework.org/schema/mvc                        http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">        <!-- 会自动加载一些验证类 -->    <mvc:annotation-driven/>                <!-- 扫描包下的所有注解类 : 哪个可以处理我的请求？-->                 <context:component-scan base-package="com.controller"><context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/><context:exclude-filter type="annotation" expression="org.springframework.stereotype.Service"/><context:exclude-filter type="annotation" expression="org.springframework.stereotype.Repository"/></context:component-scan><bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"p:viewClass="org.springframework.web.servlet.view.JstlView"p:prefix="/WEB-INF/view/"p:suffix=".jsp"/><!--  <bean id="jsonConvert" class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter"></bean>--></beans>

因为没有hibernate.cfg.xml，所以要在Entity中配置相应的注解：

package com.entity;import javax.persistence.Column;import javax.persistence.Entity;import javax.persistence.GeneratedValue;import javax.persistence.Id;import javax.persistence.Table;import org.hibernate.annotations.GenericGenerator;/* * 这里用Hibernate的注解方式 */@Entity@Table(name="person")public class Person {String id;String name;String idCard;String phone;String address;@Id@Column(name="id", nullable=false,length=32,unique=true)@GenericGenerator(name="generator",strategy="uuid.hex")@GeneratedValue(generator="generator")public String getId() {return id;}public void setId(String id) {this.id = id;}@Column(name="name", nullable=false,length=32)public String getName() {return name;}public void setName(String name) {this.name = name;}@Column(name="idCard", nullable=false,length=32)public String getIdCard() {return idCard;}public void setIdCard(String idCard) {this.idCard = idCard;}@Column(name="phone", nullable=false,length=32)public String getPhone() {return phone;}public void setPhone(String phone) {this.phone = phone;}@Column(name="address", nullable=false,length=32)public String getAddress() {return address;}public void setAddress(String address) {this.address = address;}public Person(String id, String name, String idCard, String phone,String address) {super();this.id = id;this.name = name;this.idCard = idCard;this.phone = phone;this.address = address;}public Person() {super();}}
