《《《《《《《《《对oss操作，上传文件》》》》》》》》》》》》》》
第一步 导入maven依赖
<dependency> <groupId>com.aliyun.oss</groupId> <artifactId>aliyun-sdk-oss</artifactId> <version>2.8.3</version></dependency>
第二步 使用文件流上传
jsp代码：上传文件的请求模式我用的是angularjs
<body ng-controller="testController">
<div style="margin: 100px 100px;">
<input id="fileUpload" type="file" />
<button ng-click="uploadFile()">上传</button>
<button ng-click="getBucket()">获取bucket信息</button>
<ol>
<li ng-repeat="fileName in fileNameList" style="margin-top:10px;">
<a href="" ng-bind="fileName" ng-click="downFile(fileName)"></a>
</li>
</ol>
</div>
<!-- floor -->
<div th:include="/common/floor :: commonOnLoadJs"></div>
<script>
angular.module('testApp', ['ng-layer']).controller('testController', function ($scope, layer, $http) {
//上传文件
$scope.uploadFile = function(){
var form = new FormData();
var file = document.getElementById("fileUpload").files[0];
form.append('file', file);
$http({
method: 'POST',
url: '/jz-project/testController/testUpload',
data: form,
headers: {'Content-Type': undefined},
transformRequest: angular.identity
}).success(function (data) {
console.log('upload success');
}).error(function (data) {
console.log('upload fail');
})
}
//获取文件列表
$scope.getBucket = function(){
$http.post("/jz-project/testController/getBucket").success(function(result) {
console.log(2);
console.log(result);
$scope.fileNameList = result.data;
});
}
//下载文件
$scope.downFile = function (fileName) {
// alert(fileName);
//注意下载文件不能使用post提交，后台会返回输出流对象，post返回的数据浏览器没法解析弹出下载框
//还会报错：getOutputStream() has already been called for this response
window.location.href = "testController/downFile?fileName="+fileName;
// $http.post("/jz-project/testController/downFile", fileName).success(function(result) {
// console.log(2);
// console.log(result);
// getBucket();
// });
}
})
</script>
</body>

controller代码
/**
* @Description: 上传文件到oss
* @auther: zrt
* @date: 2018/9/5 15:15
*/
@RequestMapping(value = "/testUpload", method = RequestMethod.POST,produces={"application/json;charset=UTF-8"})
@ResponseBody
public ResultBase<String> testUpload(@RequestParam(value = "file" , required = true) MultipartFile file) {
log.info("开始上传文件");
ResultBase<String> rb = new ResultBase<String>();
log.info("文件名："+file.getOriginalFilename());
//上传到oss
if(file != null){
OssTestUtil.ossUploadFileStream(file);
}
rb.setCode(0);
rb.setData("");
return rb;
}

自己封装的OssTestUtil工具
/**
* @Description: 文件流上传oss
* @auther: zrt
* @date: 2018/9/5 15:19
*/
public static void ossUploadFileStream(MultipartFile file){
// Endpoint以杭州为例，其它Region请按实际情况填写。
String endpoint = ENDPOINT;
// 阿里云主账号AccessKey拥有所有API的访问权限，风险很高。强烈建议您创建并使用RAM账号进行API访问或日常运维，请登录 https://ram.console.aliyun.com 创建RAM账号。
String accessKeyId = ACCESS_KEYID;
String accessKeySecret = ACCESS_KEY_SECRET;
// 创建OSSClient实例。
OSSClient ossClient = new OSSClient(endpoint, accessKeyId, accessKeySecret);
// 上传文件流。
// InputStream inputStream = null;
try {
//三个参数，1、bucket的名称，2、文件名称、3、文件输入流
PutObjectResult por = ossClient.putObject("zrt888888", file.getOriginalFilename(), file.getInputStream());
} catch (IOException e) {
e.printStackTrace();
}
// 关闭OSSClient。
ossClient.shutdown();
}

我还是把代码直接保存百度云吧
