概述：我真服了，这个垃圾学校还在教jsp，这种技术我虽然早会了，但是之前搞的大多都是springboot web类型的，这里我就复习一下，避免以后忘记这种垃圾技术
第一步：创建maven项目
第二步：添加依赖
pom.xml文件

第三步：开始配置tomcat
第四步：开始配置项目
然后点击apply即可
将依赖全部引入WEB-INF下的lib里面（在idea里面的目录是不会显示的）
第五步：写点jsp文件
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Insert title here</title>
</head>
<body>
登录页面！
</body>
</html>

第六步：编写controller文件
package org.cyl.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
/**“@Controller”表示IndexController的实例是一个控制器
* @Controller相当于@Controller("indexController")
* 或@Controller(value = "indexController")
*/
@Controller
@RequestMapping("/index")
public class IndexController {
@RequestMapping("/login")
public String login() {
/**login代表逻辑视图名称，需要根据Spring MVC配置
* 文件中internalResourceViewResolver的前缀和后缀找到对应的物理视图
*/
return "login";
}
@RequestMapping("/register")
public String register() {
return "register";
}
}

第七步：编写配置文件
package org.cyl.config;
import javax.servlet.ServletContext;
import javax.servlet.ServletException;
import javax.servlet.ServletRegistration.Dynamic;
import org.springframework.web.WebApplicationInitializer;
import org.springframework.web.context.support.AnnotationConfigWebApplicationContext;
import org.springframework.web.servlet.DispatcherServlet;
public class WebConfig implements WebApplicationInitializer{
@Override
public void onStartup(ServletContext arg0) throws ServletException {
AnnotationConfigWebApplicationContext ctx
= new AnnotationConfigWebApplicationContext();
ctx.register(SpringMVCConfig.class);//注册Spring MVC的Java配置类SpringMVCConfig
ctx.setServletContext(arg0);//和当前ServletContext关联
/**
* 注册Spring MVC的DispatcherServlet
*/
Dynamic servlet = arg0.addServlet("dispatcher", new DispatcherServlet(ctx));
servlet.addMapping("/");
servlet.setLoadOnStartup(1);
}
}

package org.cyl.config;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;
import org.springframework.web.servlet.view.InternalResourceViewResolver;
@Configuration
@EnableWebMvc
@ComponentScan("org.cyl.controller")
public class SpringMVCConfig implements WebMvcConfigurer {
/**
* 配置视图解析器
*/
@Bean
public InternalResourceViewResolver getViewResolver() {
InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
viewResolver.setPrefix("/WEB-INF/jsp/");
viewResolver.setSuffix(".jsp");
return viewResolver;
}
/**
* 配置静态资源
*/
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/html/**").addResourceLocations("/html/");
}
}
