SDK for Java如何引入？

引入 POM 依赖

    <dependency>
      <groupId>com.aliyun.openservices</groupId>
      <artifactId>aliyun-log</artifactId>
      <version>0.6.6</version>
    </dependency>
开始一个 Java 程序

```java
public class LogstashForJavaDemo {
    public static void main(String[] args) throws LogException {
        DateFormat dateFormat = new java.text.SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
        /**
         * endpoint: 数据写入存储所在区域
         * project,logstore: 构成基本数据存储目标
         * accessKeyId,accessKeySecret: 构成访问密钥
         *
         * 注意: 请用户根据实际情况填写
         */
        String endpoint = "cn-hangzhou.log.aliyuncs.com";

        String accessKeyId = "uamEirofbYdTLexL";
        String accessKeySecret = "PBjsdr2dggBoYBrrprc9w02tX9UxBH";
        int logGroupSize = 10;// 建议100-2000，每个batch发送数据上限
        List<String> examples = new ArrayList<String>();
        examples.add("|c0a895e114526786450161001d1ed9|9|EADS|BIZ-MONITOR|0|类目=男装&区域=杭州&eventTeyp=1&性别=1&价格=2140|");

        // 构建一个客户端实例
        Client client = new Client(endpoint, accessKeyId, accessKeySecret);
        // 连续发送10个数据包，每个数据包有10条日志
        long currentTime = System.currentTimeMillis();

重要参数说明

参数    说明
endpoint    数据写入区域(endpoint 列表)
accessKeyId    写入数据时的秘钥 id
accessKeySecret    写入数据时的秘钥密码
project    写入数据的 project id
logstore    写入数据的 logstore id
注意：

ARMS 颁发的 accessKeyId，accessKeySecret 非用户阿里云 AK／SK，需要从 ARMS 获取，请查阅读获取方式。
project id 和 logstore id 唯一确定一个数据源。
