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
