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

　　　　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

 package Po;

 public class Stuinfo implements java.io.Serializable{
     private String id;
     private String name;
     private String sex;
     private int age;
     private float weight;
     public String getId() {
         return id;
     }
     public void setId(String id) {
         this.id = id;
     }
     public String getName() {
         return name;
     }
     public void setName(String name) {
         this.name = name;
     }
     public String getSex() {
         return sex;
     }
     public void setSex(String sex) {
         this.sex = sex;
     }
     public int getAge() {
         return age;
     }
     public void setAge(int age) {
         this.age = age;
     }
     public float getWeight() {
         return weight;
     }
     public void setWeight(float weight) {
         this.weight = weight;
     }

 }

stuinfo.hbm.xml映射文件

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

 <!DOCTYPE struts PUBLIC
 "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
 "http://struts.apache.org/dtds/struts-2.0.dtd">

 <struts>
     <!-- Configuration for the default package. -->
     <package name="default" extends="struts-default">

         <action name="lookMessageAction" class="studentAction.LookMessageAction">
             <result name="success">/student/lookMessage.jsp</result>
             <result name="input">/student/index.jsp</result>
         </action>
         <action name="addMessageAction" class="studentAction.AddMessageAction">
             <result name="success" type="chain">lookMessageAction</result>
             <result name="input">/student/addMessage.jsp</result>
         </action>
         <action name="findMessageAction" class="studentAction.FindMessageAction">
             <result name="success">/student/updateMessage.jsp</result>
             <result name="input">/student/findMessage.jsp</result>
         </action>
         <action name="updateMessageAction" class="studentAction.UpdateMessageAction">
             <result name="success" type="chain">lookMessageAction</result>
             <result name="input">/student/updateMessage.jsp</result>
         </action>
         <action name="deleteMessageAction" class="studentAction.DeleteMessageAction">
             <result name="success" type="chain">lookMessageAction</result>
             <result name="input">/student/deleteMessage.jsp</result>
         </action>

     </package>
 </struts>

相应的Java方法

 package studentAction;

 import Dao.StudentDao;
 import com.opensymphony.xwork2.ActionSupport;
 import java.util.List;
 import javax.servlet.http.HttpServletRequest;
 import org.apache.struts2.ServletActionContext;

 public class LookMessageAction extends ActionSupport{
     private HttpServletRequest request;
     private String message="input";
     public String execute() throws Exception{
         request=ServletActionContext.getRequest();
         StudentDao dao=new StudentDao();
         List list=dao.findAllInfo();
         request.getSession().setAttribute("count", list.size());
         request.getSession().setAttribute("allInfo", list);
         message="success";
         return message;
     }
 }

6，在web.xml中配置启动Struts2框架的过滤器

 <?xml version="1.0" encoding="UTF-8"?>
 <web-app version="2.4"
     xmlns="http://java.sun.com/xml/ns/j2ee"
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
     http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

     <filter>
         <filter-name>struts2</filter-name>
         <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
     </filter>

     <filter-mapping>
         <filter-name>struts2</filter-name>
         <url-pattern>/*</url-pattern>
     </filter-mapping>

   <welcome-file-list>
     <welcome-file>index.jsp</welcome-file>
   </welcome-file-list>
 </web-app>

7，编写显示界面jsp文件
