  • 1. 实现步骤
  • 2. 问题描述
  • 3. 问题原因
  • 4. 解决办法
  • 5. 附log4j2在Apollo中的配置

1. 实现步骤

通过编写ApolloLog4j2ConfigurationFactory类继承ConfigurationFactory，然后重写getConfiguration方法，在获取log4j2初始配置信息时从Apollo中读取配置信息并初始化log4j2。

实现代码：

package com.dm.dmga.log4j;

import com.ctrip.framework.apollo.Config;
import com.ctrip.framework.apollo.ConfigChangeListener;
import com.ctrip.framework.apollo.ConfigService;
import com.ctrip.framework.apollo.model.ConfigChange;
import com.ctrip.framework.apollo.model.ConfigChangeEvent;
import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.core.LoggerContext;
import org.apache.logging.log4j.core.config.Configuration;
import org.apache.logging.log4j.core.config.ConfigurationFactory;
import org.apache.logging.log4j.core.config.ConfigurationSource;
import org.apache.logging.log4j.core.config.Order;
import org.apache.logging.log4j.core.config.plugins.Plugin;
import org.apache.logging.log4j.core.config.properties.PropertiesConfigurationBuilder;

import java.net.URI;
import java.util.Enumeration;
import java.util.Properties;
import java.util.Set;

3. 问题原因

在spring的配置文件beans-common.xml中，引入了apollo:config导致该问题。

依赖链如下：
apollo:config > ConfigUtil初始化 > Log4j2初始化 > ApolloLog4j2ConfigurationFactory初始化 > ConfigUtil初始化

但是，一旦在加载apollo:config之前就初始化Log4j2就不存在该问题。

4. 解决办法

综合上述问题分析，其实只要在Apollo的NameSpaceHandler初始化之前先初始化Log4j2即可解决问题。

主要解决思路：
1. Hook Apollo的NamespaceHandler，提前加载Log4j2。（没办法覆盖spring.handlers配置文件中的内容）
2. 在各种各样的工程启动时先加载Log4j2
3. 在Spring启动之前加载Log4j2（一定要在NamespaceHandler加载前）

4.1 基于Hook Apollo NamespaceHandler方式

这里又可以采用两种方式：
* 在当前工程添加同名的NamespaceHandler类以达到覆盖Apollo框架中的该类
* 添加自定义的NamespaceHandlder。
* 自定义一个NamespaceHandler继承于Apollo的NamespaceHandler
* 在springs.handler文件自定义一个key（namespace），然后指定value为NamespaceHandler类
* 在spring.schemas文件中指定xsd位置
* 在xsd文件中指定其namespace为刚才在springs.handler中定义的key

这么麻烦的主要原因是spring中无法直接覆盖jar包中定义的NamespaceHandler

具体操作如下：
1. 添加同名NamespaceHandler类

1. 自定义NamespaceHandler（没有选择这个）

4.2 在Spring启动之前加载Log4j2（现在采用的方案）

尝试过各种Spring提供的Listener，它们的启动时机都比NamespaceHandler初始化时机晚，所以也就达不到要求。

最后，回头一想，Spring也用到了Logger框架，那么Spring加载过程中肯定会加载Log4j2吧。

经过查找，发现Spring采用的为commons-logging框架。那么现在只需要在工程中添加对应的bridge依赖包即可。

        <!-- Commons-Logging Log4j2 Bridge -->
        <dependency>
            <groupId>org.apache.logging.log4j</groupId>
            <artifactId>log4j-jcl</artifactId>
            <version>2.11.0</version>
        </dependency>

通过该bridge，spring启动时直接先启动了log4j2，完美解决问题。
