springboot集成阿里OSS上传文件
开发前的准备：
自己在阿里云上申请免费的Oss对象存储，新建Bucket---读写权限选择公共读,我开始这里忘了导致后来踩了小坑
接下来是代码中的一些配置：我用的是springboot
1》添加pom依赖:
com.aliyun.oss
aliyun-sdk-oss
2.8.3
2》yml配置：
oss:
endpoint: http://oss-cn-hangzhou.aliyuncs.com
accessKeyId: 你自己的---阿里云右上角头像点击选择可以获取
accessKeySecret: 你自己的---阿里云右上角头像点击选择可以获取
bucketName: tao11140------你自己创建的bucket节点
key: group1/pic-----------目录前缀
webserver: https://tao11140.oss-cn-hangzhou.aliyuncs.com3》添加配置类：
OssProperties：@Data
@ConfigurationProperties(prefix = "oss")
public class OssProperties {
private String endpoint;
private String accessKeyId;
private String accessKeySecret;
private String bucketName;
private String key;
private String webserver;
}OssConfig：Configuration
@EnableConfigurationProperties(OssProperties.class)
public class OssConfig {
@Autowired
private OssProperties ossProperties;
@Bean
public OSSClient getOSSClient(){
ClientConfiguration conf=new ClientConfiguration();
// Set the maximum number of allowed open HTTP connections
conf.setMaxConnections(1000);
conf.setConnectionTimeout(600000);
conf.setSocketTimeout(600000);
OSSClient client = new OSSClient(ossProperties.getEndpoint(),ossProperties.getAccessKeyId(),ossProperties.getAccessKeySecret(),conf);
return client;
}
}
OssClientUtils：@Component
public class OssClientUtils {
@Autowired
private OssConfig ossConfig;
@Autowired
private OssProperties ossProperties;
/**
* 上传图片
* @param file
* @param nfixName
* @param schoolId
* @return
*/
public String uploadPic(MultipartFile file, String nfixName, Long schoolId, String module){
String result=""; //返回图片路径
OSSClient ossClient =null;
String key=assembleOssPath(schoolId,module,nfixName); //目标oss文件路径
try {
ossClient=ossConfig.getOSSClient();
PutObjectResult tip=ossClient.putObject(ossProperties.getBucketName(), key, new ByteArrayInputStream(file.getBytes()));
if(tip!=null && !"".equals(tip.getETag())) {
// result = key;
result = ossProperties.getWebserver() + "/" + key;
}
}catch (Exception ex){
ex.printStackTrace();
}
return result;
}
public String uploadPic(MultipartFile file, String nfixName, String module){
String result=""; //返回图片路径
OSSClient ossClient =null;
String key=assembleOssPath(module,nfixName); //目标oss文件路径
try {
ossClient=ossConfig.getOSSClient();
PutObjectResult tip=ossClient.putObject(ossProperties.getBucketName(), key, new ByteArrayInputStream(file.getBytes()));
if(tip!=null && !"".equals(tip.getETag())) {
// result = key;
result = ossProperties.getWebserver() + "/" + key;
}
}catch (Exception ex){
ex.printStackTrace();
}
return result;
}
private List getFileList(HttpServletRequest request, String key){
//创建一个通用的多部分解析器
CommonsMultipartResolver multipartResovler = new CommonsMultipartResolver();
//判断 request 是否有文件上传,即多部分请求
if (!multipartResovler.isMultipart(request)) {
//无附件上传
return null;
}
// 转型为MultipartHttpRequest：
MultipartHttpServletRequest multipartRequest = (MultipartHttpServletRequest) request;
// 获得文件：
List files = multipartRequest.getFiles(key);
System.out.println(files.size());
return files;
}
public String uploadImage(HttpServletRequest request, String module) {
Map files = this.getFileMap(request);
String result = "";
if (files == null || files.keySet().size() <=0) {
return result;
}
for(String key : files.keySet()){
MultipartFile file = files.get(key);
// 获取文件名
String uploadFileName = file.getOriginalFilename();
if(StringUtils.isBlank(uploadFileName)){
return result;
}
//不带.的后缀
String nfixName = uploadFileName.substring(uploadFileName.lastIndexOf(".")+1);
result = this.uploadPic(file, nfixName, module);
return result;
}
return null;
}
public Map getFileMap(HttpServletRequest request){
//创建一个通用的多部分解析器
CommonsMultipartResolver multipartResovler = new CommonsMultipartResolver();
//判断 request 是否有文件上传,即多部分请求
if (!multipartResovler.isMultipart(request)) {
//无附件上传
return null;
}
// 转型为MultipartHttpRequest：
MultipartHttpServletRequest multipartRequest = (MultipartHttpServletRequest) request;
// 获得文件：
Map files = multipartRequest.getFileMap();
return files;
}
//组装上传路径
private String assembleOssPath(Long schoolId,String ossConstant,String suffix){
return ossProperties.getKey()+schoolId+ossConstant+ UUID.randomUUID().toString().replace("-", "")+"."+suffix;
}
private String assembleOssPath(String ossConstant,String suffix){
return ossProperties.getKey()+ossConstant+ UUID.randomUUID().toString().replace("-", "")+"."+suffix;
}
}
4》测试Controller:
@Api(value="OssController",description="oss上传文件测试",tags={"oss上传文件测试"})
@RestController
@RequestMapping("oss")
public class OssController {
@Autowired
private OssClientUtils ossClientUtils;
@RequestMapping(value = "uploadPic",method = RequestMethod.POST)
public String uploadOss(HttpServletRequest request,String path) {
return ossClientUtils.uploadImage(request, path);
}
}
至此，代码已经准备完毕，接下来postman本地模拟上传图片看看：
postman需要这么传：
首先传参需要传递需要自定义保存的路径，我这里是test
设置Headers:
选择上传文件：
发送请求后，报错：
Caused by: java.lang.NoClassDefFoundError: org/apache/commons/fileupload/disk/DiskFileItemFactory
解决：
缺少pom依赖：
commons-fileupload
commons-fileupload
1.2.2
net.sf.staccatocommons
commons-io
1.2
再次发送请求：
OK图片上传成功，返回图片路径
浏览器中访问显示：
AccessDenied
You do not have read permission on this object.

tao11140.oss-cn-hangzhou.aliyuncs.com
神码，竟然没有权限？？？赶紧去阿里云后台看了下，图片确实是上传成功了
那么可能是要设置一个全局的读取权限
在oss后台的基础设置中找到读写权限，更改为公共读即可
接下来我尝试上传一个apk文件到oss，大概一兆多的大小，结果报错：
The field file exceeds its maximum permitted size of 1048576 bytes.
查看文档之后，原因可能是springboot限制了单次请求的文件大小
解决：
Spring Boot1.4版本后配置更改为:
spring.http.multipart.maxFileSize = 10Mb
spring.http.multipart.maxRequestSize=100Mb Spring Boot2.0之后的版本配置修改为:
spring.servlet.multipart.max-file-size = 10MB
spring.servlet.multipart.max-request-size=100MB我的yml添加配置如下：如果是想要不限制文件上传的大小，那么就把两个值都设置为-1就行
spring:
servlet:
multipart:
max-file-size: 10MB
max-request-size: 100MB
之后重新请求上传apk,上传成功
至此，springboot集成oss文件上传圆满成功
