Hibernate Spring Struts Bean MySQL

1、新建一个Web Project，命名为S2SH，并将项目编码改为UTF-8。

2、拷贝以下jar包到lib文件夹里面：

antlr-2.7.6.jar

asm.jar

cglib-2.1.3.jar

commons-collections.jar

commons-fileupload-1.2.1.jar

commons-logging-1.0.4.jar

dom4j-1.6.1.jar

freemarker-2.3.13.jar

hibernate3.jar

jstl.jar

jta.jar

log4j-1.2.11.jar

mysql-connector-java.jar

ognl-2.6.11.jar

spring.jar

standard.jar

struts2-core-2.1.6.jar

struts2-spring-plugin-2.1.6.jar

xwork-2.1.2.jar

3、修改web.xml文件，如下：

<?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">
 
 <!-- 指定spring配置文件 -->
 <context-param>
  <param-name>contextConfigLocation</param-name>
  <param-value>classpath:applicationContext*.xml</param-value>
 </context-param>
 
 <!-- 对Spring容器进行实例化 -->
 <listener>
  <listener-class>
   org.springframework.web.context.ContextLoaderListener
  </listener-class>
 </listener>
 
 <!-- 编码过滤器(要放在struts2前面配置) -->
 <filter>
  <filter-name>encodeFilter</filter-name>
  <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
  <init-param>
   <param-name>encoding</param-name>
   <param-value>UTF-8</param-value>
  </init-param>   
        <init-param>   
            <param-name>forceEncoding</param-name>   
            <param-value>true</param-value>   
        </init-param>
 </filter>
 <filter-mapping>
  <filter-name>encodeFilter</filter-name>
  <url-pattern>/*</url-pattern>
 </filter-mapping>
 
 <!-- struts2 配置 -->
 <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>

4、hibernate.cfg.xml，如下：

<?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="connection.username">root</property>
		<property name="connection.password">123456</property>
		<property name="connection.url">
			jdbc:mysql://localhost:3306/test
		</property>
		<property name="dialect">
			org.hibernate.dialect.MySQLDialect
		</property>
		<property name="myeclipse.connection.profile">
			com.mysql.jdbc.Driver
		</property>
		<property name="connection.driver_class">
			com.mysql.jdbc.Driver
		</property>
		<property name="show_sql">true</property>
		<property name="format_sql">true</property>
		<mapping resource="orm/TbUser.hbm.xml" />

	</session-factory>

</hibernate-configuration>

5、applicationContext.xml，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"
	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">

	<bean id="sessionFactory"
		class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
		<property name="configLocation"
			value="classpath:hibernate.cfg.xml" />
	</bean>

	<bean id="userDAO" class="dao.UserDAOImpl"/>
	
	<bean id="userService" class="service.UserServiceImpl">
		<property name="userDAO">
			<ref local="userDAO"/>
		</property>
	</bean>
	
	<bean id="loginAction" class="action.UserAction">
		<property name="userService">
			<ref local="userService"/>
		</property>
	</bean>
</beans>

6、struts.xml，如下：

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
    "http://struts.apache.org/dtds/struts-2.0.dtd">

<struts>
	
	<!-- 资源文件 -->
	<constant name="struts.custom.i18n.resources" value="native"/>
	<!-- Spring负责创建Action实例 -->
	<constant name="struts.objectFactory" value="spring"/>
	
	<package name="user" namespace="/user" extends="struts-default">
		<!-- action配置的class属性值和spring中bean的名称相同 -->
		<action name="*" class="loginAction" method="{1}">
			<result name="success">/index.jsp</result>
			<result name="input">/login.jsp</result>
			<result name="browse">/index.jsp</result>
		</action>
	</package>
	
</struts>

7、分页需要用到的类Page

import java.util.List;

public class Page {

	private int total;
	
	private int pageSize;
	
	private int totalPage;
	
	private int pageNo;
	
	private int prePage;
	
	private int nextPage;
	
	private List list;

	public List getList() {
		return list;
	}

	public void setList(List list) {
		this.list = list;
	}

	public int getNextPage() {
		if(pageNo==totalPage){
			nextPage=pageNo;
		}else{
			nextPage=pageNo+1;
		}
		return nextPage;
	}

	public void setNextPage(int nextPage) {
		this.nextPage = nextPage;
	}

	public int getPageNo() {
		return pageNo;
	}

	public void setPageNo(int pageNo) {
		this.pageNo = pageNo;
	}

	public int getPageSize() {
		return pageSize;
	}

	public void setPageSize(int pageSize) {
		this.pageSize = pageSize;
	}

	public int getPrePage() {
		if(pageNo==1){
			prePage=pageNo;
		}else{
			prePage=pageNo-1;
		}
		return prePage;
	}

	public void setPrePage(int prePage) {
		this.prePage = prePage;
	}

	public int getTotal() {
		return total;
	}

	public void setTotal(int total) {
		this.total = total;
	}

	public int getTotalPage() {
		if(total%pageSize==0){
			totalPage=total/pageSize;
		}else{
			totalPage=total/pageSize+1;
		}
		return totalPage;
	}

	public void setTotalPage(int totalPage) {
		this.totalPage = totalPage;
	}
	
}

8、Hibernate分页语句

public Page findByPageNo(int pageNo, int pageSize) {
		
		Page page = new Page();
		
		Query query = session.createQuery("select count(*) from TbUser");
		
		int count = Integer.parseInt(query.uniqueResult().toString());
		
		query = session.createQuery("from TbUser");
		query.setMaxResults(pageSize);
		query.setFirstResult((pageNo - 1) * pageSize);
		
		page.setList(query.list());
		page.setTotal(count);
		page.setPageNo(pageNo);
		page.setPageSize(pageSize);
		
		return page;
	}

9、JSP页面分页代码

共${page.totalPage }页 当前第${page.pageNo }页 共${page.total }条记录
    <c:if test="${page.totalPage!=1}">
    	<c:if test="${page.pageNo==1}">
    		<font color="gray">首页 上一页</font>
    		<a href="user/browse?pageNo=${page.nextPage }">下一页</a>
    		<a href="user/browse?pageNo=${page.totalPage }">尾页</a>
    	</c:if>
    	<c:if test="${page.pageNo==page.totalPage}">
    		<a href="user/browse?pageNo=1">首页</a>
    		<a href="user/browse?pageNo=${page.prePage }">上一页</a>
    		<font color="gray">下一页 尾页</font>
    	</c:if>
    	<c:if test="${page.pageNo!=1 and page.pageNo!=page.totalPage}">
    		<a href="user/browse?pageNo=1">首页</a>
    		<a href="user/browse?pageNo=${page.prePage }">上一页</a>
    		<a href="user/browse?pageNo=${page.nextPage }">下一页</a>
    		<a href="user/browse?pageNo=${page.totalPage }">尾页</a>
    	</c:if>
    </c:if>
