OpenSearch:output log SDK

Konfigurasikan output log untuk debugging

1. Pastikan dependensi Java SDK telah ditambahkan ke file pom.xml Anda, lalu tambahkan dependensi berikut:

<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-log4j12</artifactId>
    <version>1.7.12</version>
</dependency>

2. Simpan konten berikut sebagai file bernama log4j.xml dan letakkan di Direktori root classpath Anda.

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">
<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/">
    <appender name="console" class="org.apache.log4j.ConsoleAppender">
        <param name="Target" value="System.out" />
        <layout class="org.apache.log4j.PatternLayout">
            <param name="ConversionPattern" value="%d %-5p [%t] %c{1} - %m%n" />
        </layout>
    </appender>
    <appender name="logfile" class="org.apache.log4j.DailyRollingFileAppender">
        <param name="File" value="log/sdk.log" />
        <layout class="org.apache.log4j.PatternLayout">
            <param name="ConversionPattern" value="%d %p [%c] - %m%n" />
        </layout>
    </appender>
    <logger name="com.aliyun.opensearch">
        <level value="debug" />
    </logger>
    <logger name="org.apache.thrift">
        <level value="error" />
    </logger>
    <root>
        <level value="info" />
        <appender-ref ref="console" />
        <appender-ref ref="logfile" />
    </root>
</log4j:configuration>

3. (Opsional) Untuk mengubah lokasi file output log, ubah nilai dalam file log4j.xml ke jalur tujuan yang diinginkan.

 <param name="File" value="log/sdk.log" />
