SLF4J的多个绑定
我在Spring Boot应用程序中有以下错误：
SLF4J：类路径包含多个SLF4J绑定。SLF4J：在[jar：file：/opt/tomcat/webapps/ROOT/WEB-
INF/lib/slf4j-simple-1.7.13.jar！/org/slf4j/impl/StaticLoggerBinder.class]中找到绑定在[jar：file：/opt/tomcat/webapps/ROOT/WEB-
INF/lib/logback-
classic-1.1.3.jar！/org/slf4j/impl/StaticLoggerBinder.class]中SLF4J：参见http：//
www .slf4j.org /
codes.html＃multiple_bindings进行解释。
我去了链接，并尝试从我认为要导入的pom中删除slf4j-simple-1.7.13和logback-classic，但它没有用。
<dependency> <groupId>org.apache.solr</groupId>
<artifactId>solr-solrj</artifactId>
<version>${solrj.version}</version>
<exclusions>
<exclusion>
<groupId>org.slf4j</groupId>

和
<dependency> <groupId>org.apache.solr</groupId>

<version>${solrj.version}</version>
<exclusions>
<exclusion>
<groupId>ch.qos.logback</groupId>
<artifactId>logback-classic</artifactId>
</exclusion>
</exclusions>
</dependency>
Solr J版本：
<solrj.version>5.2.1</solrj.version>如何确定这是正确的违规模块？我做错了什么吗？
pom文件使用我们自己创建的spring boot父级。也许这是需要进行排除的地方？
这是org.slf4j的依赖关系树：

回答：
您是否尝试过org.slf4j:slf4j-simple在POM中添加排除项，例如：
<dependency> <groupId>com.company.io.spring.boot.starter</groupId>
<artifactId>ana-spring-boot-starter</artifactId>
<version>1.0.0</version>
<exclusions>
<exclusion>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-simple</artifactId>
</exclusion>
</exclusions>
</dependency>
