SpringMVC(一)——搭建环境

标签:eclips lang location dex mod 运行 方法调用 核心 startup SpringMVC是Spring的一个模块。MVC=Model+View+Controller,用于与前端交互,处理前端请求。 1.eclipse创建项目 File->New->Dynamic Web Project->输入名称->next->next->勾选Generate web.xml deployment descriptor(默认生成一个web.xml)->finish 2.导包 在WebContent->WEB-INF->lib下 commons-logging spring-beans spring-context spring-core spring-expression(Spring的5个核心包) spring-web spring-webmvc(MVC的核心包) 3.在WebContent->WEB-INF->web.xml中配置SpringMVC的核心(前端)控制器DispatcherServlet 注意点,两个 4.创建控制器类,需要实现Controller接口,后面学会注解就用注解 5.配置springmvc-config.xml,配置控制器映射文件 6.创建视图页面 WebContent->WEB-INF->jsp->index.jsp 7.运行进入http://localhost:8080/MVC_01/firstController 由于我的eclipse有些问题,打开无法立即获取界面,需要手动输路径,也不清楚为啥。 SpringMVC(一)——搭建环境 标签:eclips lang location dex mod 运行 方法调用 核心 startup 原文地址:https://www.cnblogs.com/shoulinniao/p/12952861.htmlxml version="1.0" encoding="UTF-8"?>
