嵌入式Tomcat通过logback/sl4j进行日志记录 [英] Embedded Tomcat logging over logback / sl4j

问题描述

如何使嵌入式tomcat通过logback写入其日志?我发现了一些有关将独立的tomcat与log4j一起使用的信息.但是对于嵌入式tomcat和logback来说，设置看起来如何?

How can I make an embedded tomcat write its logs over logback? I found some info about using a standalone tomcat with log4j. But how does the setup look like for an embedded tomcat and logback?

这些是Maven依赖项:

These are the maven dependencies:

<dependency>
    <groupId>ch.qos.logback</groupId>
    <artifactId>logback-core</artifactId>
    <version>${logback.version}</version>
</dependency>
<dependency>
    <groupId>org.apache.tomcat.embed</groupId>
    <artifactId>tomcat-embed-core</artifactId>
    <version>${tomcat.version}</version>
</dependency>
<dependency>
    <groupId>org.apache.tomcat.embed</groupId>
    <artifactId>tomcat-embed-logging-juli</artifactId>
    <version>${tomcat.version}</version>
</dependency>
<dependency>
    <groupId>org.apache.tomcat.embed</groupId>
    <artifactId>tomcat-embed-logging-log4j</artifactId>
    <version>${tomcat.version}</version>
</dependency>
<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>log4j-over-slf4j</artifactId>
    <version>${sl4j.version}</version>
</dependency>
<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>jul-to-slf4j</artifactId>
    <version>${sl4j.version}</version>
</dependency>

我知道Spring Boot会自动进行tomcat日志记录集成.但是在这种情况下，我不能使用Spring.

I know that Spring Boot does the tomcat logging integration automatically. But in this case I cannot use Spring.

推荐答案

尝试添加代码以安装网桥:

Try to add the code to install the bridge:

SLF4JBridgeHandler.removeHandlersForRootLogger();
SLF4JBridgeHandler.install();

并删除依赖项:

<dependency>
    <groupId>org.apache.tomcat.embed</groupId>
    <artifactId>tomcat-embed-logging-log4j</artifactId>
    <version>${tomcat.version}</version>
</dependency>
