Grails 4 war 部署到 Tomcat 失败，没有这样的方法：reactor.core.publisher.Mono.from(Publisher)Mono/invokeStatic

问题描述

类似问题：Grails got error when war file deployed to Heroku (Factory method 'requestMappingHandlerAdapter' threw exception)

但是我在将 grails 4.0.11 生成的 war 文件部署到 Tomcat(v8.5.39) 时遇到了这个问题：

Caused by: org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter]: Factory method 'requestMappingHandlerAdapter' threw exception; nested exception is java.lang.BootstrapMethodError: java.lang.IllegalAccessError: no such method: reactor.core.publisher.Mono.from(Publisher)Mono/invokeStatic

我正在从 grails 3.3.11 升级项目。

WAR 正在使用 ./gradlew bootWar 构建。

本地开发环境没有问题。

解决方法

我进行了依赖项扫描并搜索了任何与 reactive 相关的内容。

它发现 reactive-streams 是 micronaut 的依赖项。

+--- org.grails:grails-core -> 4.0.10
|    +--- org.codehaus.groovy:groovy:2.5.14
|    +--- org.slf4j:slf4j-api:1.7.30
|    +--- org.slf4j:jcl-over-slf4j:1.7.30
|    |    \--- org.slf4j:slf4j-api:1.7.30
|    +--- io.micronaut:micronaut-inject:1.3.7
|    |    +--- org.slf4j:slf4j-api:1.7.26 -> 1.7.30
|    |    +--- javax.annotation:javax.annotation-api:1.3.2
|    |    +--- javax.inject:javax.inject:1
|    |    +--- io.micronaut:micronaut-core:1.3.7
|    |    |    +--- org.slf4j:slf4j-api:1.7.26 -> 1.7.30
|    |    |    +--- org.reactivestreams:reactive-streams:1.0.3

排除它解决了问题，但我不知道它可能导致什么后果。

configurations.all {
    exclude group: 'org.reactivestreams',module: 'reactive-streams'
}

在 war 时部署到 Tomcat 工作正常，并且该应用程序目前看起来很稳定。
