ignite系列之14--log4j2日志配置

Ignite支持各种常见的日志库和框架：

• JUL (默认)；
• Log4j2；
• JCL；
• SLF4J。

ignite默认日志介绍（无需配置）见：https://www.cnblogs.com/yangh2016/p/17221433.html

但上述日志方式在与log4j标准不同，在生产环境存在一些问题，故需要配置log4j的方式

.如何配置使用Log4j2？

1、配置文件

                    <RollingFile name="Rolling-${sys:nodeId}" fileName="${sys:IGNITE_HOME}/work/log/ignite-${sys:nodeId}.log"

                        <DefaultRolloverStrategy max="30"/>
                    </RollingFile>

        <!--

            consistency warnings.

            <AppenderRef ref="FILE" level="DEBUG"/>
        </Root>
    </Loggers>
</Configuration>

1）日志级别：Root level="debug">
2）日志文件大小：

<SizeBasedTriggeringPolicy size="100 MB" />
3）压缩后的文件个数：

 <DefaultRolloverStrategy max="30"/>
日志文件效果：

2、jar包依赖

maven工程需要添加如下依赖

 <dependency>
                <groupId>org.apache.ignite</groupId>
                <artifactId>ignite-log4j2</artifactId>
                <version>${ignite.version}</version>
            </dependency>

对于使用ignite部署包（apache-ignite-2.14.0-bin）需要把依赖包的目录移动到libs目录

 3、java代码示例（配置log4j2）

IgniteConfiguration cfg = new IgniteConfiguration();
IgniteLogger log = new Log4J2Logger("log4j2-config.xml");
cfg.setGridLogger(log);
// Start a node.
try (Ignite ignite = Ignition.start(cfg)) {
    ignite.log().info("Info Message Logged!");
}

4、ignite配置文件配置log4j2

<bean class="org.apache.ignite.configuration.IgniteConfiguration" id="ignite.cfg">
    <property name="gridLogger">
        <bean class="org.apache.ignite.logger.log4j2.Log4J2Logger">
            <!-- log4j2 configuration file -->
            <constructor-arg type="java.lang.String" value="config/log4j2-config.xml"/>
        </bean>
    </property>
</bean>
