1、项目结构
2、所需jar包
3、web.xml
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">
<display-name>spring</display-name> <context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/spring-context.xml,/WEB-INF/applicationContext.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener> <!-- log4j配置文件路径 -->
<context-param>

<param-name>log4jRefreshInterval</param-name>
<param-value>6000</param-value>
</context-param> <!-- 加载log4j配置文件 -->
<listener>
<listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
</listener> <!-- springmvc配置 -->
<servlet>
<servlet-name>springMVC</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/spring-config.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>springMVC</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping> <welcome-file-list>
<welcome-file>index.html</welcome-file>
<welcome-file>index.htm</welcome-file>
<welcome-file>index.jsp</welcome-file>
<welcome-file>default.html</welcome-file>
<welcome-file>default.htm</welcome-file>
<welcome-file>default.jsp</welcome-file>
</welcome-file-list>
</web-app>
注：ContextLoaderListener作用：Spring之ContextLoaderListener的作用
4、applicationContext.xml，配置hibernate
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</property> <!-- 以下列表写入实体类 -->

</property>
</bean>
<bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory"/>
</bean>
<!-- 使用annotation定义事务 -->
<tx:annotation-driven transaction-manager="transactionManager" />
</beans>
5、spring-mvc.xml，springmvc配置文件
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

<property name="suffix" value=".jsp" />
</bean>
</beans>
6、News.java
package com.demo; import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id; @Entity
public class News { @Id
@GeneratedValue
private long id;
private String title;
private String contend; public long getId() {
return id;
}
public void setId(long id) {
this.id = id;
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public String getContend() {
return contend;
}
public void setContend(String contend) {
this.contend = contend;
} }
7、java.lang.NoClassDefFoundError: [Lorg/hibernate/engine/FilterDefinition错误
原先：<bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean"> 改成：<bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
