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。

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,

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>

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。
