struts2+spring3.0+hibernate注解方式

最近用这三个东西开发了一个后台管理的程序，现在写出来希望能够讨论谈论，因为我刚开始弄有很多东西都还不知道，在这里写出来望大家发现到问题后能够给我留言，以便完善，呵呵~

第一步：导入工程需要的包，具体需要哪些包，如果有需要的话我可以提供，当然最好的就是去官网下载了，呵呵~

第二步：配置web.xml文件。我的web.xml文件如下：

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
	<!-- 默认i18n资源文件 -->
	<context-param>
		<param-name>javax.servlet.jsp.jstl.fmt.localizationContext</param-name>
		<param-value>i18n/messages</param-value>
	</context-param>
	
    <!--
        Location of the Log4J config file, for initialization and refresh checks.
        Applied by Log4jConfigListener.
    -->
    <context-param>
        <param-name>log4jConfigLocation</param-name>
        <param-value>/WEB-INF/classes/log4j.properties</param-value>
    </context-param>
    
	<filter>
		<filter-name>struts2</filter-name>
		<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
		<init-param>
			<param-name>actionPackages</param-name>
			<param-value>com.cssweb.tradeadmin.action.trade</param-value>
		</init-param>
	</filter>

	<filter-mapping>
		<filter-name>struts2</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>
	
	<!-- 著名 Character Encoding filter -->
	<filter>
		<filter-name>encodingFilter</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>
	</filter>

    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/applicationContext.xml</param-value>
    </context-param>

	<!-- Spring 刷新Introspector防止内存泄露 -->
	<listener>
		<listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class>
	</listener>
    
    <session-config>
        <session-timeout>30</session-timeout>
    </session-config>
	
	<!-- Error Page定义 -->
	<error-page>
		<error-code>500</error-code>
		<location>/commons/error.jsp</location>
	</error-page>
	<error-page>
		<error-code>404</error-code>
		<location>/commons/404.jsp</location>
	</error-page>
	<error-page>
		<error-code>403</error-code>
		<location>/commons/403.jsp</location>
	</error-page>
	
    <welcome-file-list>
        <!-- Redirects to "welcome.htm" for dispatcher handling -->
        <welcome-file>index.jsp</welcome-file>
    </welcome-file-list>
 
</web-app>

第三步：配置strust.xml文件（由于我用的是注解驱动方式，所以只有这一个文件）

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN"
    "http://struts.apache.org/dtds/struts-2.1.dtd">
<struts>
        <constant name="struts.custom.i18n.resources" value="globalMessages" />
    	<constant name="struts.convention.package.locators" value="action" /> 
        <constant name="struts.i18n.encoding" value="UTF-8" />
        <!-- when you used to real please set false -->
        <constant name="struts.devMode" value="true" />
        <!-- 将struts2委托Spring管理 -->
 	    <constant name="struts.objectFactory" value="spring" /> 
	    
        <package name="mydefault" extends="struts-default">
			
		    <global-results>
			    <!-- 下面定义的结果对所有的Action都有效 -->
			    <result name="exception">/commons/error.jsp</result>
			    <result name="login">/login/login.jsp</result>
		    </global-results>

		    <global-exception-mappings>
			    <!-- 指Action抛出Exception异常时，转入名为exception的结果。 -->
			    <exception-mapping exception="java.lang.Exception" result="exception"/>
		    </global-exception-mappings>
        </package> 
         
</struts>

第四步：配置spring的xml文件包含hibernate的引入

<?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:jee="http://www.springframework.org/schema/jee" xmlns:tx="http://www.springframework.org/schema/tx"
		xmlns:aop="http://www.springframework.org/schema/aop"
		xsi:schemaLocation="
			http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
			http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd
			http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-2.5.xsd
			http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsd
			http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd">
    
    <context:component-scan base-package="com.cssweb.tradeadmin.action"/>
    
    <bean id="propertyConfigurer"
          class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"
          p:location="/WEB-INF/jdbc.properties" />
    
    <bean id="dataSource"
          class="org.springframework.jdbc.datasource.DriverManagerDataSource"
          p:driverClassName="${jdbc.driverClassName}"
          p:url="${jdbc.url}"
          p:username="${jdbc.username}"
          p:password="${jdbc.password}" />
    
    <!-- ADD PERSISTENCE SUPPORT HERE (jpa, hibernate, etc) -->
    <!-- Hibernate SessionFactory -->
    <bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"
                p:dataSource-ref="dataSource">
        <property name="hibernateProperties">
                <props>
                        <prop key="hibernate.dialect">${hibernate.dialect}</prop>
                        <prop key="hibernate.show_sql">${hibernate.show_sql}</prop>
                        <prop key="hibernate.generate_statistics">${hibernate.generate_statistics}</prop>
                </props>
        </property>
        <property name="mappingResources">
        		<list>
        			<value>com/cssweb/tradeadmin/model/UserBasicInfo.hbm.xml</value>
        			<value>com/cssweb/tradeadmin/model/LogLoginToday.hbm.xml</value>
        			<value>com/cssweb/tradeadmin/model/CustHostInfo.hbm.xml</value>
        	</list>
        </property>
        <property name="eventListeners">
                <map>
                        <entry key="merge">
                                <bean class="org.springframework.orm.hibernate3.support.IdTransferringMergeEventListener"/>
                        </entry>
                </map>
        </property>
    </bean>

    <!-- Transaction manager for a single Hibernate SessionFactory (alternative to JTA) -->
    <bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager"
                p:sessionFactory-ref="sessionFactory"/>

    <!-- Transaction manager that delegates to JTA (for a transactional JNDI DataSource) -->
    <!--
    <bean id="transactionManager" class="org.springframework.transaction.jta.JtaTransactionManager"/>
    -->


    <!-- ========================= BUSINESS OBJECT DEFINITIONS ========================= -->

    <!--
        Activates various annotations to be detected in bean classes:
        Spring's @Required and @Autowired, as well as JSR 250's @Resource.
    -->
    <context:annotation-config/>

    <!--
        Instruct Spring to perform declarative transaction management
        automatically on annotated classes.
    -->
    <tx:annotation-driven/>

    <!--
        Exporter that exposes the Hibernate statistics service via JMX. Autodetects the
        service MBean, using its bean name as JMX object name.
    -->
    <context:mbean-export/>
    
    
    <aop:aspectj-autoproxy/>

    <!-- PetClinic's central data access object: Hibernate implementation -->
    <bean id="clinic" class="com.cssweb.tradeadmin.dao.hibernate.HibernateClinic"/>
</beans>

第五步：在action包里面建action类：

/**
 * Copyright 2010 CssWeb Microsystems, Inc. All rights reserved.
 * CssWeb PROPRIETARY/CONFIDENTIAL. Use is subject to license terms.
 *
 * @(#)LoginAction.java 1:58:01 PM Apr 15, 2010
 */
package com.cssweb.tradeadmin.action;

import java.util.List;
import java.util.Map;

import javax.servlet.http.HttpServletRequest;

import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.apache.struts2.ServletActionContext;
import org.apache.struts2.convention.annotation.Action;
import org.apache.struts2.convention.annotation.Namespace;
import org.apache.struts2.convention.annotation.ParentPackage;
import org.apache.struts2.convention.annotation.Result;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Scope;
import org.springframework.stereotype.Controller;

import com.cssweb.common.exception.BussinessException;
import com.cssweb.common.util.MD5;
import com.cssweb.tradeadmin.dao.Clinic;
import com.cssweb.tradeadmin.model.UserBasicInfo;
import com.opensymphony.xwork2.ActionContext;
import com.opensymphony.xwork2.ActionSupport;

/**
 * 交易系统后台登录
 *
 * @author hujun
 * @version 1.0
 * @see
 * @since 1.0
 */
@Controller
@ParentPackage("mydefault") 
@Namespace("/user")
@Scope("prototype")
public class LoginAction extends ActionSupport {
	/**
	 * 
	 */
	private static final long serialVersionUID = 7454734463309586123L;

	private Log log = LogFactory.getLog(LoginAction.class);
	
    private final Clinic clinic;
    
    private String loginName;
    private String loginPwd;
    private String incode;
    
    @Autowired
    public LoginAction(Clinic clinic) {
        this.clinic = clinic;
    }
    
    @Action(value="login", 
    		results={@Result(name="success", location="/index.jsp", type="redirect"),
    				 @Result(name="input", location="/login/login.jsp")})
    public String login() {
    	System.out.println(">>>>>>>>>>>>>>>>>>>>" + loginName);
    	System.out.println(">>>>>>>>>>>>>>>>>>>>" + loginPwd);
    	System.out.println(">>>>>>>>>>>>>>>>>>>>" + incode);
    	String msg = "";
    	try {
    		Map session = ActionContext.getContext().getSession();
    		String vnum = (String)session.get("vnum");
    		if(vnum!=null&&!vnum.toLowerCase().equals(incode.toLowerCase())) {
    			msg="验证码不正确！";
    		}
    		else {
        		MD5 md5 = new MD5();
            	UserBasicInfo user = new UserBasicInfo();
            	user.setUserName(loginName);
            	user.setPassword(md5.getMD5ofStr(loginPwd));
    			List<?> list = this.clinic.queryList(user, 0, 1, null, false);
    			if(list!=null&&list.size()>0) {
    				session.put("userName", loginName);
    				session.put("password", loginPwd);
    			}
    			else {
    				msg="用户和密码不正确！";
    			}
    		}
    		HttpServletRequest request = ServletActionContext.getRequest();
    		request.setAttribute("msg", msg);
		} catch (BussinessException e) {
			log.error(e);
		}
		System.out.println(">>>>>>>>>>>>##########" + msg);
    	return msg.equals("") ? SUCCESS : "input";
    }

	public String getLoginName() {
		return loginName;
	}

	public void setLoginName(String loginName) {
		this.loginName = loginName;
	}

	public String getLoginPwd() {
		return loginPwd;
	}

	public void setLoginPwd(String loginPwd) {
		this.loginPwd = loginPwd;
	}

	public String getIncode() {
		return incode;
	}

	public void setIncode(String incode) {
		this.incode = incode;
	}
}

第六步：hibernate类，在这里action中的Clinic是接口，hibernate类集成这个接口

	@Autowired
	private SessionFactory sessionFactory;
	
    /**
     * 保存（新建或者更新）
     */
    public void merge(Object obj) throws BussinessException {
        try {
            Session session = sessionFactory.openSession();
            Transaction t=session.beginTransaction();
            session.merge(obj);
            t.commit();
        }catch(RuntimeException e){
        	log.error(e);
        	throw new BussinessException(e);
        }
    }
    
    /**
     * 保存（新建或者更新）
     */
    public void save(Object obj) throws BussinessException {
        try {
            Session session = sessionFactory.openSession();
            Transaction t=session.beginTransaction();
            session.save(obj);
            t.commit();
        }catch(RuntimeException e){
        	log.error(e);
        	throw new BussinessException(e);
        }
    }
    
    /**
     * 保存（新建或者更新）
     */
    public void update(Object obj) throws BussinessException {
        try {
            Session session = sessionFactory.openSession();
            Transaction t=session.beginTransaction();
            session.update(obj);
            t.commit();
        }catch(RuntimeException e){
        	log.error(e);
        	throw new BussinessException(e);
        }
    }
    /**
     * 保存（新建或者更新）
     */
    public void saveOrupdate(Object obj) throws BussinessException {
        try {
            Session session = sessionFactory.openSession();
            Transaction t=session.beginTransaction();
            session.saveOrUpdate(obj);
            t.commit();
        }catch(RuntimeException e){
        	log.error(e);
        	throw new BussinessException(e);
        }
    }

由于部分代码设计到公司正在运营的项目，所以不能贴出忘大家原谅！另外如果大家对这块比较感兴趣的话希望可以多交流交流，比如我这里的struts.xml文件的配置不完整，总之我把我会的都写出来希望能够给大家个参考，同时也希望高手能够指点下，呵呵~
