【IT168 技术文档】struts2释出已经很久了,虽然自己现在作GUI开发,不过有时间还是学习下web开发,现在就将我使用myeclipse工具应用struts2 + spring + hibernate 实现CRUD操作的步骤一一纪录下来,为初学者少走弯路略尽绵薄之力!
首先,myeclipse中web工程目录结构如下图:
其中持久类AbstractTest,Test,TestDAO,Test.hbm.xml都是myeclipse的hibernate工具生成的.TestAction类是struts2的核心处理类,代码如下:
package com.yangqiang.strutsdemo.web;import java.util.Collection;import java.util.List;import org.apache.log4j.Logger;import com.opensymphony.xwork2.ActionSupport;import com.yangqiang.strutsdemo.domain.Test;import com.yangqiang.strutsdemo.domain.TestDAO;

*/public class TestAction extends ActionSupport ...{ private static final Logger log = Logger.getLogger(TestAction.class); private Integer id; private Integer[] ids; protected TestDAO testDao; private Test test; private Collection<Test> testColl; 
/** *//** * 描述 return 返回 ids。 * @author Stone yang * @date 2007-4-24
*/ public Integer[] getIds() ...{ return ids; } /** *//** * 描述:设置ids的值。 * @param ids * @author Stone yang * @date 2007-4-24 */ public void setIds(Integer[] ids) ...{ this.ids = ids; } /** *//** * 描述 return 返回 testColl。 * @author Stone yang * @date 2007-4-24 */ public Collection<Test> getTestColl() ...{ return testColl; } /** *//** * 描述:设置testColl的值。 * @param testColl * @author Stone yang * @date 2007-4-24 */ public void setTestColl(Collection<Test> testColl) ...{ this.testColl = testColl; } /** *//** * 描述 return 返回 id。 * @author Stone yang * @date 2007-4-24 */ public Integer getId() ...{ return id; } /** *//** * 描述:设置id的值。 * @param id * @author Stone yang * @date 2007-4-24 */ public void setId(Integer id) ...{ this.id = id; } /** *//** * 描述 return 返回 testDao。 * @author Stone yang * @date 2007-4-24 */ public TestDAO getTestDao() ...{ return testDao; } /** *//** * 描述:设置testDao的值。 * @param testDao * @author Stone yang * @date 2007-4-24 */ public void setTestDao(TestDAO testDao) ...{ this.testDao = testDao; } /** *//** * 描述 return 返回 test。 * @author Stone yang * @date 2007-4-24 */ public Test getTest() ...{ return test; } /** *//** * 描述:设置test的值。 * @param test * @author Stone yang * @date 2007-4-24 */ public void setTest(Test test) ...{ this.test = test; } public String load() ...{ test = getTestDao().findById(id); return SUCCESS; } @SuppressWarnings("unchecked") public String list() ...{ testColl = getTestDao().findByExample(new Test()); return SUCCESS; } public String store() ...{ getTestDao().merge(test); return SUCCESS; } public String remove() ...{ for (int i = 0, size = ids.length; i < size; i++) ...{ getTestDao().delete(getTestDao().findById(ids[i])); } return SUCCESS; } }applicationContext.xml 主要是工具生成 的,只是将配置文件路径改下,代码如下:
<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd"><beans> <bean id="struts" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"> <property name="configLocation"> <!-- 改变了一下--> <value>/WEB-INF/classes/hibernate.cfg.xml</value> </property> </bean> <bean id="testDao" class="com.yangqiang.strutsdemo.domain.TestDAO"> <property name="sessionFactory"> <ref bean="struts" /> </property> </bean></beans>struts.xml (变化不大,写过以前struts配置文件的不难理解)
