阿里云日志服务Java SDK使用教程

项目地址:https://gitcode.com/gh_mirrors/al/aliyun-log-java-sdk

项目介绍

阿里云日志服务（Log Service，简称SLS）Java SDK是一个开源项目，提供了对日志服务API的封装。通过该SDK，开发者可以方便地调用日志服务的所有API接口。该项目托管在GitHub上，地址为：aliyun-log-java-sdk。

项目快速启动

环境准备

• Java开发环境
• Maven项目管理工具

添加依赖

在您的Maven项目中，添加以下依赖：

<dependency>
    <groupId>com.aliyun.openservices</groupId>
    <artifactId>aliyun-log</artifactId>
    <version>0.6.10</version>
</dependency>

初始化客户端

以下是一个简单的示例，展示如何初始化日志服务客户端：

import com.aliyun.openservices.log.Client;

public class LogServiceExample {
    public static void main(String[] args) {
        String accessId = "your_access_id";
        String accessKey = "your_access_key";
        String host = "your_endpoint";

        Client client = new Client(host, accessId, accessKey);
        System.out.println("Client initialized successfully.");
    }
}

创建Logstore

以下示例展示如何创建一个Logstore：

import com.aliyun.openservices.log.common.LogStore;
import com.aliyun.openservices.log.exception.LogException;

public class CreateLogstoreExample {
    public static void main(String[] args) {
        String project = "your_project_name";
        String logstore = "your_logstore";
        int ttlInDay = 3;
        int shardCount = 10;

        LogStore store = new LogStore(logstore, ttlInDay, shardCount);
        try {
            client.CreateLogStore(project, store);
            System.out.println("Logstore created successfully.");
        } catch (LogException e) {
            System.err.println("Failed to create logstore: " + e.getMessage());
        }
    }
}

应用案例和最佳实践

使用Aliyun Log Java Producer写入日志数据

为了提高系统的IO效率，建议使用Aliyun Log Java Producer来写入日志数据。以下是一个简单的示例：

import com.aliyun.openservices.log.producer.LogProducer;
import com.aliyun.openservices.log.producer.ProducerConfig;
import com.aliyun.openservices.log.producer.ProjectConfig;
import com.aliyun.openservices.log.producer.LogProducer;
import com.aliyun.openservices.log.producer.LogItem;

public class ProducerExample {
    public static void main(String[] args) {
        ProducerConfig config = new ProducerConfig();
        LogProducer producer = new LogProducer(config);
        producer.putProjectConfig(new ProjectConfig("your_project_name", "your_endpoint", "your_access_id", "your_access_key"));

        LogItem logItem = new LogItem();
        logItem.PushBack("key1", "value1");
        producer.send("your_logstore", logItem, null);
        producer.flush();
        producer.close();
    }
}

通过消费组消费数据

为了消费日志服务中的数据，建议使用高级消费库Consumer Library。以下是一个简单的示例：

import com.aliyun.openservices.log.consumer.LoghubClientBuilder;
import com.aliyun.openservices.log.consumer.Consumer;
import com.aliyun.openservices.log.consumer.ConsumerConfig;

public class ConsumerExample {
    public static void main(String[] args) {
        ConsumerConfig config = new ConsumerConfig("your_project_name", "your_logstore", "your_consumer_group", "your_endpoint", "your_access_id", "your_access_key");
        Consumer consumer = new Consumer(config, new LoghubClientBuilder().build(config));
