每一步都需要看仔细，我在这里踩了几个坑，花了不好时间才弄好

 

1.新建maven项目

看仔细，不是默认的点next，选择webapp的

此时需要先设定一下文件目录，我就是一个目录弄错了，结果调试了半天：

 2.配置pom.xml

<?xml version="1.0" encoding="UTF-8"?>

3.日志配置：在src/main/resources目录下面新建logback.xml

<?xml version="1.0" encoding="UTF-8"?>
<configuration scan="true" scanPeriod="1 seconds">
	<contextListener class="ch.qos.logback.classic.jul.LevelChangePropagator">
		<resetJUL>true</resetJUL>
	</contextListener>
	
	<jmxConfiguration/>
	
	<appender name="console" class="ch.qos.logback.core.ConsoleAppender">
		<encoder>
			<pattern>logbak: %d{HH:mm:ss.SSS} %logger{36} - %msg%n</pattern>
		</encoder>
	</appender>
	
	<logger name="org.springframework,web" level="DEBUG"/>
	<root level="info">
		<appender-ref ref="console"/> 
	</root>
</configuration>

 

4.展示页面：在src/main/resources/views目录下面新建index.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
</head>
<body>
	<pre>
		hello spring-mvc
	</pre>
</body>
</html>

 

5.springMvc配置文件：

package com.wisely.highlight_springmvc7;

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;

/**
 * 视图解析器，SpringMVC实现ViewResolver，重写resolveViewName()，返回view.view用于使用model,request,response并将渲染的视图返回给浏览器
 */
@Configuration
@EnableWebMvc
@ComponentScan("com.wisely.highlight_springmvc7")
public class MyMvcConfig {
	@Bean
	public InternalResourceViewResolver viewResolver(){
		InternalResourceViewResolver internalResourceViewResolver = new InternalResourceViewResolver();
		internalResourceViewResolver.setPrefix("/WEB-INF/classes/views/");
		internalResourceViewResolver.setSuffix(".jsp");
		internalResourceViewResolver.setViewClass(JstlView.class);
		return internalResourceViewResolver;
	}
}

 

6.web配置文件

package com.wisely.highlight_springmvc7;

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;

/**
 * 实现WebApplicationInitializer可以替代xml
 */
public class WebInitializer implements WebApplicationInitializer {

	@Override
	public void onStartup(ServletContext servletContext) throws ServletException {
		AnnotationConfigWebApplicationContext context = new AnnotationConfigWebApplicationContext();
		context.register(MyMvcConfig.class);
		context.setServletContext(servletContext);//新建WebApplicationContext，注册配置类，并与servletContext关联
		
		//注册SpringMVC的DispatcherServlet
		Dynamic servlet = servletContext.addServlet("dispatcher", new DispatcherServlet(context));
		servlet.addMapping("/");
		servlet.setLoadOnStartup(1);
		
	}

}

 

7.控制器

package com.wisely.highlight_springmvc7.web;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class HelloController {
	@RequestMapping("/index")
	public String hello() {
		return "index";
	}
}

 

8.部署到tomcat，运行
