线程“主”java.lang.NoSuchMethodError 中的异常：org.slf4j.impl.StaticLoggerBinder.getSingleton()

Question

Spring Boot 应用程序

我正在制作一个标签阅读器应用程序，我一直在收到这个问题

注意：我没有使用任何属性文件输入

这是我的简单 Spring 启动应用程序

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class RfidReaderApplication {

    public static void main(String[] args) {
        SpringApplication.run(RfidReaderApplication.class, args);
    }

}

*Pom.xml *

我用来构建项目的这个 pom 配置，还有一个用于 OctaneSDKJava 的外部 jar，因为它不读取来自 pom 的 OctaneSDKJava jar，所以我在外部添加了

<?xml version="1.0" encoding="UTF-8"?>

Answer 1

如the post linked in the comments 所示，您可能缺少一些 SLF4J 依赖项。然而，另一种可能性是，您的依赖项实际上具有不同版本的 SLF4J，但由于只能使用一个，因此存在冲突。请参阅this SO post。

我建议明确使用spring-boot-starter-log4j2，因为您正在使用弹簧启动并从那里开始。
