Question

我想用spring boot 1.5.10.RELEASE配置log4j。我排除了spring-boot-starter-logging并添加了log4j依赖性。在春季启动开始之前，我拥有所有日志，但是在春季启动之后，启动日志已停止。

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
    <exclusions>
        <exclusion>
        <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-logging</artifactId>
            </exclusion>
        </exclusions>
</dependency>
<dependency>
    <groupId>org.apache.logging.log4j</groupId>
    <artifactId>log4j-core</artifactId>
    <version>2.11.0</version>
</dependency>
<dependency>
    <groupId>org.apache.logging.log4j</groupId>
    <artifactId>log4j-api</artifactId>
    <version>2.12.1</version>
</dependency>

控制台日志：

和log4j2.xml文件：

<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="INFO">

        <Console name="LogToConsole" target="SYSTEM_OUT">

        </Console>
        <File name="LogToFile" fileName="logs/app.log">
            <PatternLayout>
                <Pattern>%d %p %c{1.} [%t] %m%n</Pattern>
            </PatternLayout>
        </File>
    </Appenders>
    <Loggers>
        <Logger name="src.main.java" level="debug" additivity="false">
            <AppenderRef ref="LogToFile"/>
            <AppenderRef ref="LogToConsole"/>
        </Logger>
        <Logger name="org.springframework.boot" level="error" additivity="false">
            <AppenderRef ref="LogToConsole"/>
        </Logger>
        <Root level="error">
            <AppenderRef ref="LogToFile"/>
            <AppenderRef ref="LogToConsole"/>
        </Root>
    </Loggers>
</Configuration>

知道我在做什么错吗？

您正在使用

<Logger name="src.main.java" level="debug" additivity="false"> .  == I simply replaced it with my package name present inside src/main/java and its now working.

就我而言，更改如下：-

<Loggers>
    <Logger name="com.example.demo.test" level="debug" additivity="false">
        <AppenderRef ref="fileLogger"/>
        <AppenderRef ref="console"/>
    </Logger>

    <Root level="info">
        <AppenderRef ref="fileLogger"/>
        <AppenderRef ref="console"/>
    </Root>
</Loggers>

Spring Boot停止log4j日志记录
