在点燃默认配置文件中添加log4j属性后，服务无法启动 [英] After adding log4j property in ignite default config file, service not able to start

问题描述

我正在尝试通过使用配置文件中的gridLogger属性来启用Log4j记录器，如下所示:

I'm trying to enable Log4j logger by using the gridLogger property in the config file like below:

<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>

但是当启动ignite.sh时，由于无法读取属性参数，它给出了以下错误.

But when starting the ignite.sh it is giving below error as it is not able to read the property parameter.

推荐答案

错误指出您具有无效的元素属性:

The error states that you have an invalid element property:

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

在第一行，您偶尔会有一个封闭的 bean id ="grid.cfg" 标记，但没有值.

At the very first line, you occasionally have a closed bean id="grid.cfg" tag without a value.

应该是:

<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ignite-log4j.jar包含为项目依赖项.对于Maven:

Also, do not forget to include the ignite-log4j.jar as a project dependency. For maven:

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