Spring boot 2.0替换默认日志框架logback到 Slf4j + log4j2

第一步  移除默认日志加载依赖

            <artifactId>spring-boot-starter-test</artifactId>
            <exclusions>
                <exclusion>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-starter-logging</artifactId>

                    <artifactId>spring-boot-starter-logging</artifactId>
                </exclusion>
            </exclusions>
        </dependency>
<dependency>
            <groupId>org.springframework.boot</groupId>

                </exclusion>
            </exclusions>
        </dependency>

 第二步  增加slf4j + log4j2依赖

 

<!--支持log4j2异步日志必需 -->

<dependency>

    <groupId>com.lmax</groupId>

    <artifactId>disruptor</artifactId>

</dependency>

  

<!-- 日志API框架slf4j核心包--> 

<dependency> 

    <groupId>org.slf4j</groupId> 

    <artifactId>slf4j-api</artifactId> 

</dependency> 

<dependency> 

    <groupId>org.slf4j</groupId> 

    <artifactId>jcl-over-slf4j</artifactId> 

</dependency> 

     

<!--增加log4j2依赖--> 

<dependency> 

    <groupId>org.springframework.boot</groupId> 

    <artifactId>spring-boot-starter-log4j2</artifactId> 

</dependency>
