spring-boot - Log4j2 - 无法识别的转换说明符 [xwEx] 从转换模式中的位置 160 开始

Question

我在一个 Maven 多模块项目中有一个 SpringBoot 应用程序，我正在使用 Log4j2 进行日志记录。

当我使用测试运行构建时，一些模块有一个奇怪的日志记录异常，并记录了来自未知(不是我的)类的更多行。

这是一个异常(exception):

然后我得到这条线:

然后我看到未知日志(关于我的类(class)的前两行):

这是我得到这些奇怪东西的模块中的 log4j2-test.xml:

<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="INFO">
    <Appenders>
        <Console name="stdout">
            <PatternLayout pattern="MyApp: %d{yyyy-MM-dd HH:mm:ss,SSS} %5p [%t] %c{1.}:%L - %m%n"/>
        </Console>
    </Appenders>

    <Loggers>
        <Logger name="com.my.app" level="debug" additivity="false">

        </Logger>
        <Logger name="org.springframework" level="warn" additivity="false">

        <Logger name="org.springframework.context.annotation.ConfigurationClassEnhancer" level="error"

        <Root level="info">

        </Root>
    </Loggers>
</Configuration>

最后是模块的 pom.xml:

Answer 1

有一个问题报告说 Spring Boot 1.5 与 Log4j 2.8 不兼容。 https://github.com/spring-projects/spring-boot/issues/9172

我在使用 Spring Boot 1.5 和 Log4j 2.8.2 时遇到了像你这样的错误，而当我切换到 Log4j 2.7 时这些错误就消失了
