Maven搭建struts2+spring+hibernate环境

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，

<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 http://maven.apache.org/maven-v4_0_0.xsd">

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

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。
