Maven搭建struts2+spring+hibernate环境（一）

Maven搭建struts2+spring+hibernate环境（一）

本文简单的使用STS的自带的maven插件工具搭建ssh（struts2+spring+hibernate）开发环境，图文并茂，简单上手，适合新手。

原文地址：http://www.cnblogs.com/xmzzp/p/4177866.html

关于STS的介绍，请参考另一篇文章《Java IDE介绍：Spring开发利器-spring-tool-suite》地址：http://blog.csdn.net/sgl731524380/article/details/8831540

首先，STS自带的maven的插件已经默认有了maven，但是不建议使用默认的 maven。更改STS默认的maven可在windows-preferences-Maven  选项下，同时我将在另一篇文章里也有介绍，《STS，MyEclipse中Maven配置》 地址：http://blog.csdn.net/sgl731524380/article/details/8871470

一、新建Maven项目。

       New--Project--Maven Project，

next.

next,输入webapp,检索，选中maven-aechetype-webapp

 next，

Finish即可。

项目结构如图（修改了pom.xml文件，使用JUnit4）：

二、搭建struts2+spring+hibernate

 双击打开pom.xml，配置pom.xml文件。配置如下，

 

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0

保存，Maven会自动联网去下载所有需要的jar包，至于只写jar的名字，不用记住，只要去Maven中央仓库去搜索，Maven中央仓库地址：http://search.maven.org/

完成之后，多了很多jar，并且都放到了配置的本地仓库中，以后要再使用相同版本的jar时候，就不需要联网下载了。

 这时候，所有需要的jar都到齐了。

后面一篇我将演示如何写一个小小的程序来验证ssh框架搭建是否成功。

Maven搭建struts2+spring+hibernate环境（二）

一、修改项目结构

上一篇中我们已经完成了jar的引入，现在开始构建测试程序。刚刚完成的 project图标上可能有一个红色的叉，只需要把项目复制--粘贴--重命名。即可解决，并不是项目搭建错误所致，这可能是IDE的一个bug吧，在 MyEclipse中搭建也出现这种情况，解决方法一样。

 但是，构建的MSSH项目的结构并不是一个标准的Maven结构，我们需要手动新建几个Source Folder（注意：是source folder，不是package！！）。

完成后的结构如下：

src/main.java:存放java源文件

src/main/resources:存放项目配置文件，如spring.xml,hibernate.cfg.xml。。。

src/test/java:存放test的java文件

src/test/resources:存放test时候所需的配置文件

二、编写程序

建立如下的结构

编写配置文件，各种配置的含义我在此就不累赘了，有ssh使用基础的同学都能看懂的。

struts.xml

 

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN" "http://struts.apache.org/dtds/struts-2.3.dtd"><struts>    <!-- 将Action交给spring容器管理 -->    <constant name="struts.objectFactory" value="spring" />    <!-- 模式为开发模式，修改xml配置文件会自动加载，项目交付的时候设置为false,以免影响性能 -->    <constant name="struts.devMode" value="true" />    <constant name="struts.configuration.xml.reload" value="true" />    <!-- 字符集编码 -->    <constant name="struts.i18n.encoding" value="utf-8" />    <package name="defaultPackage" namespace="/" extends="struts-default">            <action name="userAction" class="userAction" method="reg">        <result name="success">/success.jsp</result>        <result name="error">/error.jsp</result>    </action>    </package></struts>

 

spring.xml

 

<?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:context="http://www.springframework.org/schema/context"    xsi:schemaLocation="    http://www.springframework.org/schema/beans     http://www.springframework.org/schema/beans/spring-beans-3.0.xsd     http://www.springframework.org/schema/context     http://www.springframework.org/schema/context/spring-context-3.0.xsd    ">    <!-- 引入属性文件 -->    <context:property-placeholder location="classpath:database.properties" />    <!-- 自动扫描dao和service包(自动注入) -->    <context:component-scan base-package="com.sgl.action,com.sgl.dao.impl,com.sgl.service" /></beans>

编写java文件，采用MVC架构,使用hibernate，spring注解

UserDaoI.java

 

package com.sgl.dao;import java.io.Serializable;public interface UserDaoI<T>{    public Serializable save(T o);}

 

UserDaoImpl.java

package com.sgl.dao.impl;import java.io.Serializable;import org.hibernate.SessionFactory;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Repository;import com.sgl.dao.UserDaoI;@Repository("userDao")public class UserDaoImpl<T> implements UserDaoI<T> {    //注入sessionfactory    @Autowired    private SessionFactory sessionFactory;    public Serializable save(T o) {        return sessionFactory.getCurrentSession().save(o);    }}

UserService.java

Maven搭建struts2+spring+hibernate环境（三）

后台功能都已完成，现在是前台的页面编写

index.jsp

 

<%@ page language="java" contentType="text/html; charset=UTF-8"    pageEncoding="UTF-8"%><!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>注册</title></head><body><form action="userAction" method="post"> <table width="207" border="0" align="center">        <tr>          <td colspan="2" align="center" nowrap="nowrap">用户注册</td>        </tr>        <tr>          <td width="68" nowrap="nowrap">用户名</td>          <td width="127" nowrap="nowrap"><label>            <input name="user.username" type="text" id="username" size="20" />          </label></td>        </tr>        <tr>          <td nowrap="nowrap">密　码</td>          <td nowrap="nowrap"><input name="user.password" type="password" id="password" size="20" maxlength="10" /></td>        </tr>        <tr>          <td colspan="2" align="center" nowrap="nowrap"><label>            <input type="submit"  value="注册" />            <input type="reset"  value="重填" />          </label></td>        </tr>  </table></form></body></html>

 

success.jsp

 

<%@ page language="java" contentType="text/html; charset=UTF-8"    pageEncoding="UTF-8"%><!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>Insert title here</title></head><body>${user.username }<br>${msg }</body></html>

 

error.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"    pageEncoding="UTF-8"%><!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>Insert title here</title></head><body>出错了。。。。。。。。。。</body></html>

至此，项目编写基本完成。

右键项目---run as---maven install

编译成功，没有错误

现在可以部署到服务器上运行了，部署，启动，浏览器输入http://localhost:8080/MSSH/或者http://localhost:8080/MSSH/index.jsp回车

注册，查看数据库，成功！

至此，Maven搭建struts2+spring+hibernate开发环境就完成了，其中还有很多不足之处，希望大家指出。
