读取阿里OSS的txt文件

一、上代码

package com.xiaoqiang.demo;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import com.aliyun.oss.OSSClient;
import com.aliyun.oss.model.ListObjectsRequest;
import com.aliyun.oss.model.OSSObject;
import com.aliyun.oss.model.OSSObjectSummary;
import com.aliyun.oss.model.ObjectListing;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.boot.CommandLineRunner;
import org.springframework.stereotype.Component;

@Component
public class test1Task implements CommandLineRunner {
    private static final Logger logger = LoggerFactory.getLogger(test1Task.class);

    @Override
    public void run(String... args) throws IOException {
        String accessKeyId = "XXXXX";
        String accessKeySecret = "XXXXX";
        String endpoint = "XXXXX";
        OSSClient ossClient = new OSSClient(endpoint, accessKeyId, accessKeySecret);

        String bucketName = "heheda-data";
        String objectName = "test.txt";
        OSSObject ossObject = ossClient.getObject(bucketName, objectName);

        InputStream inputStream = ossObject.getObjectContent();
        BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));
        String line;
        StringBuilder content = new StringBuilder();
        while ((line = reader.readLine()) != null) {
            content.append(line);
        }

        System.out.println(content.toString());
        ossClient.shutdown();
    }
}

二、Maven 配置

         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">

注意：在没有 com.taosdata.jdbc 依赖时会报错：
