标签: spring spring-boot logging gradle log4j2

我试图在我的springboot项目中包含log4j2,但是我收到以下错误。

SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/Users/mn/.gradle/caches/modules-2/files-2.1/org.apache.logging.log4j/log4j-slf4j-impl/2.10.0/8e4e0a30736175e31c7f714d95032c1734cfbdea/log4j-slf4j-impl-2.10.0.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: Found binding in [jar:file:/Users/mn/.gradle/caches/modules-2/files-2.1/ch.qos.logback/logback-classic/1.2.3/7c4f3c474fb2c041d8028740440937705ebb473a/logback-classic-1.2.3.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation.
SLF4J: Actual binding is of type [org.apache.logging.slf4j.Log4jLoggerFactory]

我的gradle文件如下所示:

dependencies {                                                                      
  compile('org.springframework.boot:spring-boot-starter') {                         
    exclude module:'spring-boot-starter-logging'                                    
  }                                                                                 
  compile('org.springframework.boot:spring-boot-starter-web')                       
  compile('org.springframework.boot:spring-boot-starter-security')                  
  compile('org.springframework.boot:spring-boot-starter-log4j2')                    
  compile('org.springframework:spring-oxm')                                         
  compile('org.codehaus.castor:castor-xml:1.3.3')                                   
  compile('org.apache.commons:commons-collections4:4.1')                            

  testCompile('org.springframework.boot:spring-boot-starter-test')   
  testCompile('org.springframework.security:spring-security-test')                  
} 

我很确定Spring-boot-starter是实现日志记录的人,这就是为什么我尝试排除它,但它不起作用。我错了,或错了吗?

修正了此问题。这是因为spring-boot-starter-web和spring-boot-starter-security都使用标准日志记录,因此必须从所有这些日志中排除它

答案 1 :(得分:0)

我用了这个

configurations {
    //eliminates logback
    all*.exclude group: 'ch.qos.logback'

    //eliminates StackOverflowError
    all*.exclude group: 'org.apache.logging.log4j', module: 'log4j-to-slf4j'
}

答案 2 :(得分:0)

spring-boot-starter 中的多个类使用 spring-boot-starter-logging

  • 就我而言,spring-boot-starter-jdbcspring-boot-starter-web

您应该使用 <exclusion> 标记排除依赖关系,如下所示:

<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>
