SSH2环境搭建

一、创建SSH2项目，导入Struts2并测试。

web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0" 
    xmlns="http://java.sun.com/xml/ns/javaee" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
    http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">
  <display-name></display-name>    
  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
  <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>*.action</url-pattern>
  </filter-mapping></web-app>

default.jsp

<%@ page language="java" contentType="text/html; charset=utf-8"
    pageEncoding="utf-8"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>default page</title>
</head>
<body>
default page
</body>
</html>

UserAction.java

package com.cwq.action;

import com.opensymphony.xwork2.ActionSupport;

public class UserAction extends ActionSupport {

    @Override
    public String execute() throws Exception {
        // TODO Auto-generated method stub
        //return super.execute();
        return SUCCESS;
    }

    /**
     * @param args
     */
    public static void main(String[] args) {
        // TODO Auto-generated method stub

    }

}

struts.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd">
<struts>
    <package name="cwq" extends="struts-default">
        <action name="showUsers" class="com.cwq.action.UserAction">
            <result name="success">default.jsp</result>
        </action>
    </package>
</struts>

发布项目，启动Tomcat，运行结果：

二、导入Spring包，配置数据源

三，Spring与Hibernate整合

在web.xml中加入

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:applicationContext.xml</param-value>
</context-param>

<listener>
       <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0" 
    xmlns="http://java.sun.com/xml/ns/javaee" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
    http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">
    
    <!-- 必须放在顶上 -->
    <!-- 指定spring的配置文件，默认从web根目录寻找配置文件，我们可以通过spring提供的classpath:前缀指定从类路径下寻找 -->
    <context-param>
       <param-name>contextConfigLocation</param-name>
       <param-value>classpath:applicationContext.xml</param-value>
    </context-param>
    <!-- 对Spring容器进行实例化 -->
    <listener>
          <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
    
  <display-name></display-name>    
  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
  <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>*.action</url-pattern>
  </filter-mapping></web-app>

applicationContext.xml(自动生成)

<?xml version="1.0" encoding="UTF-8"?>
<beans
    xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:p="http://www.springframework.org/schema/p"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">


    <bean id="dataSource"
        class="org.apache.commons.dbcp.BasicDataSource">
        <property name="driverClassName"
            value="com.mysql.jdbc.Driver">
        </property>
        <property name="url" value="jdbc:mysql://localhost:3306/sdu"></property>
        <property name="username" value="root"></property>
        <property name="password" value="064417"></property>
    </bean>
    <bean id="sessionFactory"
        class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
        <property name="dataSource">
            <ref bean="dataSource" />
        </property>
        <property name="hibernateProperties">
            <props>
                <prop key="hibernate.dialect">
                    org.hibernate.dialect.MySQLDialect
                </prop>
            </props>
        </property>
    </bean></beans>

测试，发布，启动Tomcat，如果启动成功则整合成功。

四、根据数据库反向生成代码

Users.java

package com.cwq.model;

import java.sql.Timestamp;

/**
 * Users entity. @author MyEclipse Persistence Tools
 */

public class Users implements java.io.Serializable {

    // Fields

    private Integer id;
    private String username;
    private String password;
    private Timestamp birthdate;

    // Constructors

    /** default constructor */
    public Users() {}

    /** full constructor */
    public Users(String username, String password, Timestamp birthdate) {
        this.username = username;
        this.password = password;
        this.birthdate = birthdate;
    }

    // Property accessors

    public Integer getId() {
        return this.id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    public String getUsername() {
        return this.username;
    }

    public void setUsername(String username) {
        this.username = username;
    }

    public String getPassword() {
        return this.password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    public Timestamp getBirthdate() {
        return this.birthdate;
    }

    public void setBirthdate(Timestamp birthdate) {
        this.birthdate = birthdate;
    }

}

    }

    public void setUsers(List<Users> users) {

    }

    /**
     * @param args
     */
    public static void main(String[] args) {

applicationContext.xml
加入

struts.xml

加入

<constant name="struts.objectFactory" value="spring" />

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd">

如果要指定进入某个action加入下面代码

index.jsp

<%@ page language="java" import="java.util.*" pageEncoding="GB18030"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
