虽然很基础，但是我转牛角尖了~~~~
这是几个文件
1.最重要的。Java文件
1 package com.chinasofti.hibb.struts; 2 3 4 import org.hibernate.Session; 5 import org.hibernate.SessionFactory; 6 import org.hibernate.Transaction; 7 import org.hibernate.cfg.Configuration; 8 import com.chinasofit.hibb.entity.Test; 9 import com.opensymphony.xwork2.ActionSupport; 10 11 12 13 @SuppressWarnings("serial") 14 public class HibbTest extends ActionSupport { 15 private Test test; 16 private int id; 17 18 public Test getTest() { 19 return test; 20 } 21 public void setTest(Test test) { 22 this.test = test; 23 } 24 public int getId() { 25 return id; 26 } 27 public void setId(int id) { 28 this.id = id; 29 } 30 public Session session(){ 31 Configuration config = new Configuration().configure(); 32 SessionFactory factory = config.buildSessionFactory(); 33 Session session = factory.openSession(); 34 return session; 35 } 36 //1.查找 37 public String testchazhao(){ 38 //int id= (Integer) session.getAttribute("id");可以直接获取页面上输入的ID，不用再获取什么的； 39 Session session=session(); 40 test = (Test) session.get(Test.class, id); 41 session.close(); 42 return "testchazhao"; 43 } 44 //2.添加 45 public String Zhuce(){ 46 // Session session1 = HibernateSessionFactory.getSession(); 47 Session session=session(); 48 Transaction tes = session.beginTransaction(); 49 session.save(test); 50 //id=test.getId(); 51 tes.commit(); //提交事务 52 // tes.rollback();//事务回滚 53 session.close(); //关闭Session对象 54 return "zhuce"; 55 } 56 //3.更改 57 public String update(){ 58 //1.查找出id 59 Session session =session(); 60 Transaction tx = session.beginTransaction(); 61 test = (Test)session.get(Test.class, id); 62 tx.commit(); 63 session.close(); 64 //2.更改 65 test.setName("王二小"); 66 Session session1 = session(); 67 Transaction tx1 = session1.beginTransaction(); 68 session1.update(test); 69 tx1.commit(); 70 session1.close(); 71 return "genggai"; 72 } 73 //4.删除，根据id 74 public String delete(){ 75 Session session =session(); 76 Transaction tx = session.beginTransaction(); 77 test = (Test)session.get(Test.class, id); 78 session.delete(test); 79 tx.commit(); 80 session.close(); 81 return "shanchu"; 82 } 83 } 84 85 86 87 88 89 90 91
2.就是test路径
1 <?xml version="1.0" encoding="UTF-8" ?> 2 <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd"> 3 <struts> 4 5 <package name="Ttest" namespace="/" extends="struts-default"> 6 <!-- 查找 --> 7 <action name="Hibb" class="com.chinasofti.hibb.struts.HibbTestId" > 8 <result name="hibbtestid" type="dispatcher">/testchaid.jsp</result> 9 </action> 10 <action name="HibbTest" class="com.chinasofti.hibb.struts.HibbTest" method="testchazhao"> 11 <result name="testchazhao" type="dispatcher">/testchazhao.jsp</result> 12 </action> 13 <!-- 增加 --> 14 <action name="Zhuce" class="com.chinasofti.hibb.struts.HibbTestzhuceOk" > 15 <result name="zhuceok" type="dispatcher">/testzhuce.jsp</result> 16 </action> 17 <action name="ZhuceOk" class="com.chinasofti.hibb.struts.HibbTest" method="Zhuce"> 18 <result name="zhuce" type="dispatcher">/testchazhao.jsp</result> 19 </action> 20 <!-- 修改 --> 21 <action name="Gengai" class="com.chinasofti.hibb.struts.HibbTestgengai" > 22 <result name="hibbtestgenggai" type="dispatcher">/testgenggaiid.jsp</result> 23 </action> 24 <action name="GengaiOk" class="com.chinasofti.hibb.struts.HibbTest" method="update"> 25 <result name="genggai" type="dispatcher">/testchazhao.jsp</result> 26 </action> 27 28 <!-- 删除 --> 29 <action name="Shanchu" class="com.chinasofti.hibb.struts.HibbTestshanchu" > 30 <result name="hibbtestshanchu" type="dispatcher">/testshanchu.jsp</result> 31 </action> 32 <action name="ShanchuOk" class="com.chinasofti.hibb.struts.HibbTest" method="delete"> 33 <result name="shanchu" type="dispatcher">/testchazhao.jsp</result> 34 </action> 35 36 37 38 39 </package> 40 </struts>
3.增删改查访问的路径都是通过ID，所以需要几个可以跳转ID的JSP和action。
1 package com.chinasofti.hibb.struts; 2 3 public class HibbTestgengai { 4 public String execute(){ 5 return "hibbtestgenggai"; 6 } 7 }
1 package com.chinasofti.hibb.struts; 2 3 public class HibbTestzhuceOk { 4 public String execute(){ 5 return "zhuceok"; 6 } 7 8 }
1 package com.chinasofti.hibb.struts; 2 3 public class HibbTestshanchu { 4 public String execute(){ 5 return "hibbtestshanchu"; 6 } 7 }
1 package com.chinasofti.hibb.struts; 2 3 public class HibbTestId { 4 public String execute(){ 5 return "hibbtestid"; 6 } 7 8 }
4.基本上在Struts里，最后跳转的都是查找JSP界面，这样可以知道自己到底对数据库做了什么
