4、web.xml

4.1 注册servlet

4.2 所有请求都会被springmvc拦截

<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"

    <url-pattern>/*url-pattern>
filter-mapping>

<mvc:annotation-driven>
    <mvc:message-converters register-defaults="true">
        <bean class="org.springframework.http.converter.StringHttpMessageConverter">
            <constructor-arg value="UTF-8"/>
        bean>
        <bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
            <property name="objectMapper">

    mvc:message-converters>
mvc:annotation-driven>

5、controller

5.1 文件上传的controller

第一种方式：

@RestController
public class FileController {
     

第二种方式：采用file.Transto 来保存上传的文件

/*
     * 采用file.Transto 来保存上传的文件
     */
    @RequestMapping("/upload2")
    public String  fileUpload2(@RequestParam("file") CommonsMultipartFile file, HttpServletRequest request) throws IOException {
     

5.2 文件下载

    //【下载文件】
    @RequestMapping(value="/download")
    public String downloads(HttpServletResponse response , HttpServletRequest request) throws Exception{
     
        System.out.println(" downloads()");
        //要下载的图片地址
        String  path = request.getServletContext().getRealPath("/upload");
        String  fileName = "3.jpg";
