Spring-Boot logging with log4j2?
提问by membersound
I'm using spring-boot-starter, and would like to configure log4j2.xmlto log asynchron + different content to different logfiles.
我正在使用spring-boot-starter，并希望配置log4j2.xml为将异步 + 不同的内容记录到不同的日志文件中。
I created the log4j2 file, but Springstill uses the spring-boot default logging. How can I switch the logging?
我创建了 log4j2 文件，但Spring仍然使用 spring-boot 默认日志记录。如何切换日志记录？

I've a better way:
我有更好的方法：
Exclude logback logger:
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter</artifactId> <exclusions> <exclusion> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-logging</artifactId> </exclusion> </exclusions> </dependency>Add log4j2 boot starter:
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-log4j2</artifactId> </dependency>
排除 logback 记录器：
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter</artifactId> <exclusions> <exclusion> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-logging</artifactId> </exclusion> </exclusions> </dependency>添加 log4j2 启动器：
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-log4j2</artifactId> </dependency>

Try this:
尝试这个：
Exclude spring-boot-starter-logging e.g.
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter</artifactId> <exclusions> <exclusion> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-logging</artifactId> </exclusion> </exclusions> </dependency>Add dependencies for your logging interface e.g. slf4j
<dependency> <groupId>org.apache.logging.log4j</groupId> <artifactId>log4j-slf4j-impl</artifactId> <version>2.0.2</version> </dependency>Add other logging implementations pointing to chosen logging interface e.g.
<dependency> <groupId>org.slf4j</groupId> <artifactId>jcl-over-slf4j</artifactId> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>jul-to-slf4j</artifactId> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>log4j-over-slf4j</artifactId> </dependency>Add your target logging implementation e.g.
<dependency> <groupId>org.apache.logging.log4j</groupId> <artifactId>log4j-api</artifactId> <version>2.0.2</version> </dependency> <dependency> <groupId>org.apache.logging.log4j</groupId> <artifactId>log4j-core</artifactId> <version>2.0.2</version> </dependency>
排除 spring-boot-starter-logging 例如
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter</artifactId> <exclusions> <exclusion> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-logging</artifactId> </exclusion> </exclusions> </dependency>为您的日志记录界面添加依赖项，例如 slf4j
<dependency> <groupId>org.apache.logging.log4j</groupId> <artifactId>log4j-slf4j-impl</artifactId> <version>2.0.2</version> </dependency>添加指向所选日志记录接口的其他日志记录实现，例如
<dependency> <groupId>org.slf4j</groupId> <artifactId>jcl-over-slf4j</artifactId> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>jul-to-slf4j</artifactId> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>log4j-over-slf4j</artifactId> </dependency>添加您的目标日志记录实现，例如
<dependency> <groupId>org.apache.logging.log4j</groupId> <artifactId>log4j-api</artifactId> <version>2.0.2</version> </dependency> <dependency> <groupId>org.apache.logging.log4j</groupId> <artifactId>log4j-core</artifactId> <version>2.0.2</version> </dependency>
And it should work.
它应该工作。

This is what worked for me. Having two additional exclusions. Else Application was not picking up log4j and was had conflict
这对我有用。有两个额外的排除。其他应用程序没有选择 log4j 并且发生冲突
Actual binding is of type [ch.qos.logback.classic.util.ContextSelectorStaticBinder]
实际绑定类型为 [ch.qos.logback.classic.util.ContextSelectorStaticBinder]
