这是我的5美分…

我在进行测试时也遇到了同样的问题。因此，我通过仅为测试运行时添加一个实现来解决这个问题。我在这个项目中使用gradle。

/ / https://mvnrepository.com/artifact/ch.qos.logback/logback-classic testRuntimeOnly组:'ch.qos。Logback '，名称:' Logback -classic'， 版本:“1.2.3”

     <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>slf4j-simple</artifactId>
        <version>1.7.21</version>
    </dependency>

将上述依赖项放在pom.xml文件中

我没有添加任何依赖项，我只是改变了我使用它们的方式。

预览代码

(如果您使用的是弹性搜索版本< 7.0，则取消注释此代码)

IndexRequest indexRequest = new IndexRequest(
  "twitter",
  "tweets",
  id // this is to make our consumer idempotent
).source(record.value(), XContentType.JSON);

当前代码

IndexRequest indexRequest = new IndexRequest("tweets")
  .source(record.value(), XContentType.JSON)
  .id(id); // this is to make our consumer idempotent

我使用bulkrequest，并删除了这个错误。

请将以下依赖项添加到pom以解决此问题。

<dependency>
  <groupId>org.slf4j</groupId>
  <artifactId>slf4j-simple</artifactId>
  <version>1.7.25</version>
  <scope>test</scope>
</dependency>

<dependency>
  <groupId>org.slf4j</groupId>
  <artifactId>slf4j-api</artifactId>
  <version>1.7.25</version>
</dependency>

在payara 5.191上遇到了同样的问题

Jcl-over-slf4j和slf4j-log4j12一起解决了这个问题

<properties>
  <slf4j.version>1.7.29</slf4j.version>
</properties>

<dependency>
  <groupId>org.slf4j</groupId>
  <artifactId>slf4j-api</artifactId>
  <version>${slf4j.version}</version>
  <type>jar</type>
</dependency> 

<dependency>
  <groupId>org.slf4j</groupId>
  <artifactId>jcl-over-slf4j</artifactId>
  <version>${slf4j.version}</version>
</dependency>        

<dependency>
  <groupId>org.slf4j</groupId>
  <artifactId>slf4j-log4j12</artifactId>
  <version>${slf4j.version}</version>
</dependency>

他们的官网给出了解决方案:

Failed to load class org.slf4j.impl.StaticLoggerBinder This warning message is reported when the org.slf4j.impl.StaticLoggerBinder class could not be loaded into memory. This happens when no appropriate SLF4J binding could be found on the class path. Placing one (and only one) of slf4j-nop.jar slf4j-simple.jar, slf4j-log4j12.jar, slf4j-jdk14.jar or logback-classic.jar on the class path should solve the problem. SINCE 1.6.0 As of SLF4J version 1.6, in the absence of a binding, SLF4J will default to a no-operation (NOP) logger implementation. If you are responsible for packaging an application and do not care about logging, then placing slf4j-nop.jar on the class path of your application will get rid of this warning message. Note that embedded components such as libraries or frameworks should not declare a dependency on any SLF4J binding but only depend on slf4j-api. When a library declares a compile-time dependency on a SLF4J binding, it imposes that binding on the end-user, thus negating SLF4J's purpose.

解决方案:我已经添加到我的项目中使用intellij的maven研究，我选择了slf4j-jdk14.jar。
