    1.搭建项目

    1. 创建resource/application.xml
    这几个都是静态资源的映射路径,优先级顺序为:META-INF/resources > resources > static > public
    # 默认值为 /**
    spring.mvc.static-path-pattern=
    # 默认值为 classpath:/META-INF/resources/,classpath:/resources/,classpath:/static/,classpath:/public/
    spring.resources.static-locations=这里设置要指向的路径,多个使用英文逗号隔开
    
    <?xml version="1.0" encoding="UTF-8"?>
    <beans xmlns="http://www.springframework.org/schema/beans"
           xmlns:mvc="http://www.springframework.org/schema/mvc"

        <mvc:annotation-driven/>
        <!-- 自动扫描注解的bean -->

        <bean id="dataSource"
          class="org.springframework.jdbc.datasource.DriverManagerDataSource">
            <!-- 不使用properties来配置 -->
            <!-- <property name="driverClassName" value="com.mysql.jdbc.Driver" />

        </bean>
        <!-- 自动扫描了所有的XxxxMapper.xml对应的mapper接口文件,这样就不用一个一个手动配置Mpper的映射了,只要Mapper接口类和Mapper映射文件对应起来就可以了。 -->
        <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
            <property name="basePackage"
                      value="com.lottery.dao" />
        </bean>
        <!-- 配置视图解析器 viewResolver常见的配置,具体怎么回事,在控制器类说明-->
        <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
            <property name="prefix" value="/WEB-INF/"/>
            <property name="suffix" value=".jsp"/>
            <property name="contentType" value="text/html; charset=utf-8"/>
        </bean>
        <!-- 配置Mybatis的文件 ,mapperLocations配置**Mapper.xml文件位置,configLocation配置mybatis-config文件位置-->
        <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">

            <!-- <property name="typeAliasesPackage" value="com.tiantian.ckeditor.model"
                /> -->
        </bean>
    </beans>
    
    1. 创建webapp/spring-servlet.xml
    <?xml version="1.0" encoding="UTF-8"?>
    <beans xmlns="http://www.springframework.org/schema/beans"
           xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
           xmlns:mvc="http://www.springframework.org/schema/mvc"
           xmlns:p="http://www.springframework.org/schema/p"
           xmlns:context="http://www.springframework.org/schema/context"
           xsi:schemaLocation="
    http://www.springframework.org/schema/beans
    http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
    http://www.springframework.org/schema/mvc
    http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd
    http://www.springframework.org/schema/context
    http://www.springframework.org/schema/context/spring-context-3.0.xsd">
    
        <mvc:annotation-driven/>
        <!--使spring自动搜寻test包下用@Component注解的类-->
        <context:component-scan base-package="com.lottery.controller"/>
    
        <!--viewResolver常见的配置,具体怎么回事,在控制器类说明-->
        <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
            <property name="prefix" value="/WEB-INF/"/>
            <property name="suffix" value=".jsp"/>
            <property name="contentType" value="text/html; charset=utf-8"/>
        </bean>
    
    </beans>
    
    1. 创建resource/WEB-INF/hello.jsp
    <%@ page language="java" contentType="text/html; charset=UTF-8"
             pageEncoding="UTF-8"%>
    <%--核心标签--%>
    <%@ page isELIgnored="false"%>
    <!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>
    <h1>${msg}</h1>
    </body>
    </html>
    
    1. 创建controller/HelloController.class
    package com.lottery.controller;
    
    import org.springframework.stereotype.Controller;
    import org.springframework.ui.Model;
    import org.springframework.web.bind.annotation.RequestMapping;
    
    
    @Controller
    public class HelloController {
    
        @RequestMapping("/hello")
    //    public ModelAndView sayHello(){
    //        return new ModelAndView("hello","msg","Hello, how are you?");
    //    }
        public String sayHello(Model model){
            model.addAttribute("msg", "Hello, how are you?");
            return "hello";
        }
    
    }
