struts 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struts + 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: 使用myeclipse开发hibernate和spring的操作我就不详细说了网上的教程很多如果有不明白的可以咨询我呵呵其中持久类AbstractTest Test TestDAO Test hbm xml都是myeclipse的hibernate工具生成的 TestAction类是struts 的核心处理类代码如下: package yangqiang strutsdemo web;import java util Collection;import java util List;import apache log j Logger;import opensymphony xwork ActionSupport;import yangqiang strutsdemo domain Test;import yangqiang strutsdemo domain TestDAO;/** *//** * 描述: * @author Stone yang 创建日期: * @version pattern Study * 技术支持: <a >;/a> */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 */ public Integer[] getIds() return ids; /** *//** * 描述:设置ids的值 * @param ids * @author Stone yang * @date */ public void setIds(Integer[] ids) this ids = ids; /** *//** * 描述 return 返回 testColl * @author Stone yang * @date */ public Collection<Test> getTestColl() return testColl; /** *//** * 描述:设置testColl的值 * @param testColl * @author Stone yang * @date */ public void setTestColl(Collection<Test> testColl) this testColl = testColl; /** *//** * 描述 return 返回 id * @author Stone yang * @date */ public Integer getId() return id; /** *//** * 描述:设置id的值 * @param id * @author Stone yang * @date */ public void setId(Integer id) this id = id; /** *//** * 描述 return 返回 testDao * @author Stone yang * @date */ public TestDAO getTestDao() return testDao; /** *//** * 描述:设置testDao的值 * @param testDao * @author Stone yang * @date */ public void setTestDao(TestDAO testDao) this testDao = testDao; /** *//** * 描述 return 返回 test * @author Stone yang * @date */ public Test getTest() return test; /** *//** * 描述:设置test的值 * @param test * @author Stone yang * @date */ 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(rge(test); return SUCCESS; public String remove() for (int i = 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= encoding= UTF ?><!DOCTYPE beans PUBLIC //SPRING//DTD BEAN//EN beans dtd ><beans> <bean id= struts class= springframework orm hibernate LocalSessionFactoryBean > <property name= configLocation > <! 改变了一下 > <value>/WEB INF/classes/hibernate cfg xml</value> </property> </bean> <bean id= testDao class= 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) <?xml version= encoding= UTF ?><!DOCTYPE struts PUBLIC //Apache Sofare Foundation//DTD Struts Configuration //EN dtd ><struts> <package name= struts_crud extends= struts default namespace= /test > <action name= List class= yangqiang strutsdemo web TestAction method= list > <result>list jsp</result> </action> <action name= Edit class= yangqiang strutsdemo web TestAction method= load > <result>edit jsp</result> </action> <action name= Store class= yangqiang strutsdemo web TestAction method= store > <result type= redirect >List action</result> </action> <action name= Remove class= yangqiang strutsdemo web TestAction method= remove > <result type= redirect >List action</result> </action> </package></struts>struts properties struts objectFactory = springweb xml <?xml version= encoding= UTF ?><web app version= xmlns= xmlns:xsi= instance xsi:schemaLocation= ; app_ _ xsd > <display name>Struts crud 例程</display name> <context param> <param name>contextConfigLocation</param name> <param value>classpath*:* xml</param value> </context param> <listener> <listener class> sprntext ContextLoaderListener</listener class> </listener> <filter> <filter name>struts </filter name> <filter class> apache struts dispatcher FilterDispatcher </filter class> </filter> <filter mapping> <filter name>struts </filter name> <url pattern>/*</url pattern> </filter mapping> <wele file list> <wele file>list jsp</wele file> </wele file list></web app>list jsp <% @ page language= java contentType= text/; charset=utf pageEncoding= utf %><% @ taglib prefix= s uri= /struts tags %><!DOCTYPE PUBLIC //W C//DTD XHTML Transitional//EN transitional dtd >< xmlns= ><head> <title>Book List</title> <style type= text/css > table border: px solid black; border collapse: collapse; table thead tr th border: px solid black; padding: px; background color: #cccccc; table tbody tr td border: px solid black; padding: px; </style></head><body> <h >Book List</h > <s:form action= Remove theme= simple > <table cellspacing= > <thead> <tr> <th>勾选</th> <th>ID</th> <th>名称</th> <th>作者</th> </tr> </thead> <tbody> <s:iterator value= testColl > <tr> <td><input type= checkbox name= ids value= <s:property value= id /> /></td> <td><s:property value= id /></td> <td><s:property value= name /></td> <td><s:property value= author /></td> <td> <a <s:url action= Edit ><s:param name= id value= id /></s:url> > Edit </a>   <a <s:url action= Remove ><s:param name= ids value= id /></s:url> > Delete </a> </td> </tr> </s:iterator> </tbody> </table> <s:submit value= Remove /><a >Add Test</a> </s:form> </body></>edit jsp <% @ page language= java contentType= text/; charset=utf pageEncoding= utf %><% @ taglib prefix= s uri= /struts tags %><!DOCTYPE PUBLIC //W C//DTD XHTML Transitional//EN transitional dtd >< xmlns= ><head> <title>Book</title></head><body> <h > <s:if test= null == test > Add Book </s:if> <s:else> Edit Book </s:else> </h > <s:form action= Store > <s:hidden name= test id label= ID /> <s:textfield name= test name label= 书名 /> <s:textfield name= test author label= 作者 /> <s:submit /> </s:form></body></> cha138/Article/program/Java/ky/201311/28215
