struts2+hibernate整合

1.准备好struts2+hibernate所需要的包。

 

 

2.myeclispe中，window->preferences->

3.

在web.xml中配置好Struts2框架的核心控制器

<?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" 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></display-name>
  <!-- 配置Struts2框架的核心控制器 -->
  <filter>
  	<filter-name>struts2</filter-name>
  	<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
  </filter>	
  <filter-mapping>
  	<filter-name>struts2</filter-name>
  	<url-pattern>/*</url-pattern>
  </filter-mapping>
  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
</web-app>

　　

struts.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
    "http://struts.apache.org/dtds/struts-2.3.dtd">

<struts>
    <constant name="struts.devMode" value="true"></constant>
    <package name="p1" extends="struts-default">
        
    </package>
</struts>

hibernate.cfg.xml文件

<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
        "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
        "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
	<property name="dialect">
		org.hibernate.dialect.MySQLDialect
	</property>
	<property name="hbm2ddl.auto">update</property>
	<property name="show_sql">true</property>
	<property name="current_session_context_class">thread</property>
	<property name="format_sql">true</property>
	<property name="myeclipse.connection.profile">mysql</property>


	<property name="connection.driver_class">
		com.mysql.jdbc.Driver
	</property>
	<property name="connection.username">root</property>
	<property name="connection.password">1996</property>
	<property name="connection.url">
		jdbc:mysql://localhost:3306/diylife?useUnicode=true&characterEncoding=UTF-8
	</property>


	<property name="cache.provider_class">
		org.hibernate.cache.EhCacheProvider
	</property>
	<property name="cache.use_second_level_cache">true</property>
	<property name="generate_statistics">true</property>
	<property name="cache.use_query_cache">true</property><!-- 开启查询缓存 -->
	
</session-factory>
</hibernate-configuration>

然后基本环境搭建完成了，当我在tomcat8.0上装载完项目，启动tomcat是报错如下:

Struts2配置问题java.lang.ClassNotFoundException: org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter

解决办法:方法一：右键点击项目--->build path-->configure build path-->左侧菜单栏就会看到Deployment Assembly-->右侧点击add按钮--->选择java build path entries--->next--->选择项目--->finish.

重新装载下项目，重启下tomcat,就不报错了。
