struts2+hibernate整合开发步骤

百度的各种代码，步骤，自己整合了一下

1，创建数据库

　　常用mysql   creat table.....

2，在WebContent下的bin中添加相应的包

　　http://pan.baidu.com/s/1c2DR2co

　　　　本人的百度云盘分享

3，创建实体类以及相应的映射文件、

　　例如stuinfo.java和stuinfo.hbm.xml

　　stuinfo.java中包含，私有成员对象和getter，setter方法

 1 package Po;
 2
 3 public class Stuinfo implements java.io.Serializable{
 4     private String id;
 5     private String name;
 6     private String sex;
 7     private int age;
 8     private float weight;
 9     public String getId() {
10         return id;
11     }
12     public void setId(String id) {
13         this.id = id;
14     }
15     public String getName() {
16         return name;
17     }
18     public void setName(String name) {
19         this.name = name;
20     }
21     public String getSex() {
22         return sex;
23     }
24     public void setSex(String sex) {
25         this.sex = sex;
26     }
27     public int getAge() {
28         return age;
29     }
30     public void setAge(int age) {
31         this.age = age;
32     }
33     public float getWeight() {
34         return weight;
35     }
36     public void setWeight(float weight) {
37         this.weight = weight;
38     }
39
40 }

stuinfo.hbm.xml映射文件

 1 <?xml version="1.0" encoding="UTF-8"?>
 2 <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
 3 "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
 4 <!-- Generated 2011-12-9 12:17:31 by Hibernate Tools 3.2.1.GA -->
 5 <hibernate-mapping>
 6     <class name="PO.Stuinfo" table="stuinfo" catalog="test">
 7         <id name="id" type="string">
 8             <column name="id" length="20" />
 9             <generator class="assigned" />
10         </id>
11         <property name="name" type="string">
12             <column name="name" length="20" not-null="true" />
13         </property>
14         <property name="sex" type="string">
15             <column name="sex" length="5" not-null="true" />
16         </property>
17         <property name="age" type="int">
18             <column name="age" not-null="true" />
19         </property>
20         <property name="weight" type="float">
21             <column name="weight" precision="10" scale="0" not-null="true" />
22         </property>
23     </class>
24 </hibernate-mapping>

4，配置hibernate.cfg.xml

<?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="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
    <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
    <property name="hibernate.connection.url">jdbc:mysql://localhost:3306/test</property>
    <property name="hibernate.connection.username">root</property>
    <property name="hibernate.connection.password">root</property>
    <mapping resource="PO/Stuinfo.hbm.xml"/>
  </session-factory>
</hibernate-configuration>

5，创建相应的action

即各种Java动作类以及配置方法

配置文件：     <result>中，当调用方法成功后，如果返回值与name中的字符串相同，就会跳转相应的页面

 1 <!DOCTYPE struts PUBLIC
 2 "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
 3 "http://struts.apache.org/dtds/struts-2.0.dtd">
 4
 5 <struts>
 6     <!-- Configuration for the default package. -->
 7     <package name="default" extends="struts-default">
 8
 9         <action name="lookMessageAction" class="studentAction.LookMessageAction">
10             <result name="success">/student/lookMessage.jsp</result>
11             <result name="input">/student/index.jsp</result>
12         </action>
13         <action name="addMessageAction" class="studentAction.AddMessageAction">
14             <result name="success" type="chain">lookMessageAction</result>
15             <result name="input">/student/addMessage.jsp</result>
16         </action>
17         <action name="findMessageAction" class="studentAction.FindMessageAction">
18             <result name="success">/student/updateMessage.jsp</result>
19             <result name="input">/student/findMessage.jsp</result>
20         </action>
21         <action name="updateMessageAction" class="studentAction.UpdateMessageAction">
22             <result name="success" type="chain">lookMessageAction</result>
23             <result name="input">/student/updateMessage.jsp</result>
24         </action>
25         <action name="deleteMessageAction" class="studentAction.DeleteMessageAction">
26             <result name="success" type="chain">lookMessageAction</result>
27             <result name="input">/student/deleteMessage.jsp</result>
28         </action>
29
30
31     </package>
32 </struts>

相应的Java方法

 1 package studentAction;
 2
 3 import Dao.StudentDao;
 4 import com.opensymphony.xwork2.ActionSupport;
 5 import java.util.List;
 6 import javax.servlet.http.HttpServletRequest;
 7 import org.apache.struts2.ServletActionContext;
 8
 9 public class LookMessageAction extends ActionSupport{
10     private HttpServletRequest request;
11     private String message="input";
12     public String execute() throws Exception{
13         request=ServletActionContext.getRequest();
14         StudentDao dao=new StudentDao();
15         List list=dao.findAllInfo();
16         request.getSession().setAttribute("count", list.size());
17         request.getSession().setAttribute("allInfo", list);
18         message="success";
19         return message;
20     }
21 }

6，在web.xml中配置启动Struts2框架的过滤器

 1 <?xml version="1.0" encoding="UTF-8"?>
 2 <web-app version="2.4"
 3     xmlns="http://java.sun.com/xml/ns/j2ee"
 4     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 5     xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
 6     http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
 7
 8     <filter>
 9         <filter-name>struts2</filter-name>
10         <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
11     </filter>
12
13     <filter-mapping>
14         <filter-name>struts2</filter-name>
15         <url-pattern>/*</url-pattern>
16     </filter-mapping>
17
18   <welcome-file-list>
19     <welcome-file>index.jsp</welcome-file>
20   </welcome-file-list>
21 </web-app>

7，编写显示界面jsp文件
