在点火默认配置文件中添加log4j属性后，服务无法启动

Question

我正试图通过使用配置文件中的gridLogger属性来启用Log4j记录器，如下所示：

<bean id="grid.cfg" class="org.apache.ignite.configuration.IgniteConfiguration"/>
<property name="gridLogger">
<bean class="org.apache.ignite.logger.log4j.Log4JLogger">
<constructor-arg type="java.lang.String" value="config/ignite-log4j.xml"/>
</bean>
</property>

但当启动点火开关时，由于无法读取特性参数，它给出了以下错误。

错误表明您有一个无效的元素属性：

Invalid content was found starting with element '{"http://www.springframework.org/schema/beans":property}'

在第一行，偶尔会出现一个没有值的闭合bean id="grid.cfg"标记。

应为：

<beans ...
...
<bean id="grid.cfg" class="org.apache.ignite.configuration.IgniteConfiguration">
<property name="gridLogger">
<bean class="org.apache.ignite.logger.log4j.Log4JLogger">
<constructor-arg type="java.lang.String" value="config/ignite-log4j.xml"/>
</bean>
</property>
</bean>
</beans>

此外，不要忘记将ignlight-log4j.jar作为项目依赖项包含在内。对于maven：

<dependency>
<groupId>org.apache.ignite</groupId>
<artifactId>ignite-log4j</artifactId>
<version>${ignite.version}</version>
</dependency>
