从错误日志来看，关键报错是：
Caused by: java.lang.NoSuchMethodError: ch.qos.logback.classic.spi.ILoggingEvent.getInstant()Ljava/time/Instant;问题原因
这个错误表明 ILoggingEvent.getInstant() 方法找不到，通常是由于 logback-classic 版本不兼容 造成的。
net.logstash.logback 依赖 logback-classic 1.3+，而你的项目可能使用了 1.2.x 版本，导致找不到 getInstant() 方法（该方法是在 1.3 版本引入的）。
解决方案
1. 确保 logback-classic 版本 >= 1.3
如果你的 logback-classic 仍然是 1.2.x，需要升级到 1.3.x 以上。
Maven：
<dependency>
<groupId>ch.qos.logback</groupId>
<artifactId>logback-classic</artifactId>
<version>1.3.11</version> <!-- 确保是 1.3+ 版本 -->
</dependency>Code language: HTML, XML (xml)Gradle：
implementation 'ch.qos.logback:logback-classic:1.3.11'Code language: JavaScript (javascript)然后 重新构建并运行。
2. 降级 logstash-logback-encoder 版本
如果你的 logback-classic 不能升级（例如 Spring Boot 2.x 仍然使用 1.2.x），你可以降级 logstash-logback-encoder 到 6.6 或更早版本：
<dependency>
<groupId>net.logstash.logback</groupId>
<artifactId>logstash-logback-encoder</artifactId>
<version>6.6</version> <!-- 6.6 兼容 logback 1.2 -->
</dependency>Code language: HTML, XML (xml)然后重新运行项目。
3. 检查依赖冲突
如果你仍然遇到问题，可能是 logback-classic 依赖被其他库覆盖，运行以下命令检查实际使用的版本：
Maven：
mvn dependency:tree | grep logbackGradle：
./gradlew dependencies --configuration runtimeClasspath | grep logback如果发现多个 logback-classic 版本混用，可以在 pom.xml 里排除旧版本：
<dependency>
<groupId>net.logstash.logback</groupId>
<artifactId>logstash-logback-encoder</artifactId>
<version>7.4</version>
<exclusions>
<exclusion>
<groupId>ch.qos.logback</groupId>
<artifactId>logback-classic</artifactId>
</exclusion>
</exclusions>
</dependency>Code language: HTML, XML (xml)然后 手动指定 logback-classic 版本，防止依赖冲突。
1.如果必须要用logstash7.x版本必须1升级 logback-classic 到 1.3.x 以上（推荐）。
2.如果必须使用 logback-classic 1.2.x，降级 logstash-logback-encoder 到 6.6 版本。
3.检查是否有 logback-classic 版本冲突，确保项目使用的是兼容的依赖版本。
