一、搭建步骤
总结：1.导包 通过pom.xml导包
2.编写俩个类（Spring MVC配置 + Web配置）——》这是关键的俩个配置
3.编写jsp + Controller
二、项目目录结构
三、代码展示
1、pom.xml
<project xmlns="http://maven.apache.org/POM/4.0.0"

</build>
</project>
2.Spring MVC配置
package com.yan.springmvc;
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.view.InternalResourceViewResolver;
import org.springframework.web.servlet.view.JstlView;
@Configuration
@EnableWebMvc
@ComponentScan("com.yan.springmvc")
public class MvcConfig {
@Bean
public InternalResourceViewResolver viewResolver() {
InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
viewResolver.setPrefix("/WEB-INF/classes/views/");
viewResolver.setSuffix(".jsp");
viewResolver.setViewClass(JstlView.class);
return viewResolver;
}
}
3、Web配置
package com.yan.springmvc;
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 WebInitializer implements WebApplicationInitializer{
@Override
public void onStartup(ServletContext servletContext) throws ServletException {
AnnotationConfigWebApplicationContext ctx = new AnnotationConfigWebApplicationContext();
ctx.register(MvcConfig.class);
ctx.setServletContext(servletContext);
Dynamic servlet = servletContext.addServlet("dispatcher", new DispatcherServlet(ctx));
servlet.addMapping("/");
servlet.setLoadOnStartup(1);
}
}
4、页面编写（以jsp为例子）
<%@ 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>
<pre>
Welcome to Spring MVC world
</pre>
</body>
</html>
5、编写Controller
package com.yan.springmvc.web;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class HelloController {
@RequestMapping
public String hello() {
System.out.println("---------------");
return "index";
}
}
四、提示
1、打开浏览器，输入地址：http://127.0.0.1:8080/SpringMVC/index
出现下面的页面，恭喜你，搭建成功。
2、我这个只是简单的配置，通过java配置方式
现在你们可以尝试配置log了.
