在新的 Spring Boot 应用程序中，当我 时gradle bootRun，我看到以下错误：Failed to instantiate [ch.qos.logback.classic.LoggerContext]Reported exception:java.lang.AbstractMethodError: ch.qos.logback.classic.pattern.EnsureExceptionHandling.process(Lch/qos/logback/core/Context;Lch/qos/logback/core/pattern/Converter;)V at ch.qos.logback.core.pattern.PatternLayoutBase.start(PatternLayoutBase.java:86) at ch.qos.logback.classic.encoder.PatternLayoutEncoder.start(PatternLayoutEncoder.java:28) at ch.qos.logback.classic.BasicConfigurator.configure(BasicConfigurator.java:50) at ch.qos.logback.classic.util.ContextInitializer.autoConfig(ContextInitializer.java:164) at org.slf4j.impl.StaticLoggerBinder.init(StaticLoggerBinder.java:85) at org.slf4j.impl.StaticLoggerBinder.<clinit>(StaticLoggerBinder.java:55) at org.slf4j.LoggerFactory.bind(LoggerFactory.java:150) at org.slf4j.LoggerFactory.performInitialization(LoggerFactory.java:124) at org.slf4j.LoggerFactory.getILoggerFactory(LoggerFactory.java:412) at org.slf4j.LoggerFactory.getLogger(LoggerFactory.java:357) at org.slf4j.LoggerFactory.getLogger(LoggerFactory.java:383) at com.klarna.risk.decision.application.RiskDecisionApplication.<clinit>(RiskDecisionApplication.java:14)问题是什么？

当我检查时gradle dependencyInsight --dependency logback，我看到：

似乎 Spring Boot 2.1.9 正在使用org.springframework.boot:spring-boot-starter-logging:2.1.9.RELEASE，它使用logback-classic:1.1.3. Google 的某个地方告诉我 Spring Boot 依赖管理有一个错误，该错误允许logback-core和logback-classic在这里出现不同的版本并导致冲突。
我添加了依赖项logback-core:1.1.3，问题就消失了。
compile group: 'ch.qos.logback', name: 'logback-core', version: '1.1.3'
如果您遇到同样的问题，请务必检查 Spring Boot 中使用的 logback 版本。

请尝试将这 3 个依赖项添加到您的 pom.xml 文件中。它对我有用..
<dependency>
<groupId>ch.qos.logback</groupId>
<artifactId>logback-core</artifactId>
<version>1.1.3</version>
</dependency>
<dependency>
<groupId>ch.qos.logback</groupId>
<artifactId>logback-classic</artifactId>
<version>1.2.3</version>
<scope>compile</scope>
</dependency>
<dependency>
<groupId>ch.qos.logback</groupId>
<artifactId>logback-core</artifactId>
<version>1.2.3</version>
<scope>compile</scope>
</dependency>
