使用Maven构建SSM项目架子
Maven简介
Maven项目对象模型(POM),可以通过一小段描述信息来管理项目的构建,报告和文档的项目管理工具软件。
Maven 除了以程序构建能力为特色之外,还提供高级项目管理工具。由于 Maven 的缺省构建规则有较高的可重用性,所以常常用两三行 Maven 构建脚本就可以构建简单的项目。由于 Maven 的面向项目的方法,许多 Apache Jakarta 项目发文时使用 Maven,而且公司项目采用 Maven 的比例在持续增长。
Maven这个单词来自于意第绪语(犹太语),意为知识的积累,最初在Jakata Turbine项目中用来简化构建过程。当时有一些项目(有各自Ant build文件),仅有细微的差别,而JAR文件都由CVS来维护。于是希望有一种标准化的方式构建项目,一个清晰的方式定义项目的组成,一个容易的方式发布项目的信息,以及一种简单的方式在多个项目中共享JARs。
下面我们用IDEA来搭建SSM的架子,IDEA自带Maven灰常方便!

New Project
之后一路默认就好
项目构建完毕之后,我们来到POM.XML
添加如下代码

好了,现在我们可以等等Maven帮助我们自动依赖关系了!
构建项目结构
如下图所示
我们首先在main
目录下建立一个java文件夹,之后给它赋上权限为Java文件目录,
resource文件夹,同样给它赋上resource权限,还有一个test,同样的赋上test权限
配置文件
我们需要配置SSM架子中的一些基本xml文件

创建Controller类验证程序
FirstController
package eendtech.controller;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
/**
* Created with IntelliJ IDEA.
* Description:
* Date:2019.03.14
* Author:Seale
*/
@Controller
@RequestMapping(value = "/hello")
public class FirstController{
@RequestMapping(value = "/firstController",method = RequestMethod.GET)
public String handleRequest(HttpServletRequest request, HttpServletResponse response, Model model){
model.addAttribute("msg","你好MVC");
return "first";
}
}
在我们的views目录下创建一个first.jsp
然后我们设置我们的Tomcat本地服务器,访问路径localhost:8080/项目名/hello/firstController
运行结果
到此我们的项目架子就基本建立成功啦,可以去愉快的Coding了!
