这篇文章主要介绍Spring Boot如何搭建文件上传服务，文中介绍的非常详细，具有一定的参考价值，感兴趣的小伙伴们一定要看完！
本文实例为大家分享了Spring Boot搭建文件上传服务的具体代码，供大家参考，具体内容如下
一、服务端
pom.xml
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>1.3.3.RELEASE</version> </parent> <groupId>com.test.spring</groupId> <artifactId>spring-boot</artifactId> <version>1.0.0</version> <packaging>jar</packaging> <name>spring-boot</name> <url>http://maven.apache.org</url> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <maven.compiler.source>1.8</maven.compiler.source> <maven.compiler.target>1.8</maven.compiler.target> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>commons-io</groupId> <artifactId>commons-io</artifactId> <version>2.4</version> </dependency> </dependencies> </project>package com.test.spring; import java.io.FileOutputStream; import java.io.InputStream; import java.io.OutputStream; import javax.servlet.MultipartConfigElement; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.Part; import org.apache.commons.io.IOUtils; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.EnableAutoConfiguration; import org.springframework.boot.context.embedded.MultipartConfigFactory; import org.springframework.context.annotation.Bean; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; import org.springframework.web.bind.annotation.ResponseBody; @Controller @EnableAutoConfiguration public class FileUploadController { @RequestMapping(value="/upload", method=RequestMethod.POST) @ResponseBody public String upload(HttpServletRequest request) throws Exception { Part part = request.getPart("uploadfile"); InputStream input = part.getInputStream(); OutputStream output = new FileOutputStream("d:/tmp/" + part.getSubmittedFileName()); IOUtils.copy(input, output); output.close(); input.close(); return "OK"; } @Bean MultipartConfigElement createMultipartConfigElement() { MultipartConfigFactory mcf = new MultipartConfigFactory(); mcf.setMaxFileSize("50MB"); return mcf.createMultipartConfig(); } public static void main(String[] args) throws Exception { SpringApplication.run(FileUploadController.class, args); } }注意：spring-boot-starter-web 1.3.3.RELEASE 依赖的servlet是3.1
二、客户端
客户端使用httpclient调用
先配置maven依赖
<dependency> <groupId>org.apache.httpcomponents</groupId> <artifactId>httpclient</artifactId> <version>4.5.2</version> </dependency> <dependency> <groupId>org.apache.httpcomponents</groupId> <artifactId>httpmime</artifactId> <version>4.5.2</version> </dependency>测试代码
package com.test.upload; import java.io.File; import org.apache.http.HttpEntity; import org.apache.http.client.methods.CloseableHttpResponse; import org.apache.http.client.methods.HttpPost; import org.apache.http.entity.mime.MultipartEntityBuilder; import org.apache.http.impl.client.CloseableHttpClient; import org.apache.http.impl.client.HttpClients; import org.apache.http.util.EntityUtils; public class HttpUpload { public static void main(String[] args)throws Exception { String url = "http://127.0.0.1:8080/upload"; CloseableHttpClient client = HttpClients.createDefault(); HttpPost httppost = new HttpPost(url); MultipartEntityBuilder builder = MultipartEntityBuilder.create(); builder.addBinaryBody("uploadfile", new File("D:/develop/apache-karaf-3.0.4.zip")); HttpEntity reqEntity = builder.build(); httppost.setEntity(reqEntity); CloseableHttpResponse resp = client.execute(httppost); String str = EntityUtils.toString(resp.getEntity()); System.out.println(str); resp.close(); client.close(); } }以上是“Spring Boot如何搭建文件上传服务”这篇文章的所有内容，感谢各位的阅读！希望分享的内容对大家有帮助，更多相关知识，欢迎关注编程网行业资讯频道！
