我正在使用Intellij和Gradle在Java中使用Springboot框架开发WebSocket stomp客户端和服务器的第一步。我成功地创建了一个工作示例。现在,我正在更改代码以使用java模块系统,但在启动服务器应用程序时出现以下异常
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'stompWebSocketHandlerMapping' defined in class path resource [org/springframework/web/socket/config/annotation/DelegatingWebSocketMessageBrokerConfiguration.class]: Failed to instantiate [org.springframework.web.servlet.HandlerMapping]: Factory method 'stompWebSocketHandlerMapping' threw exception with message: jakarta/websocket/Endpoint

所以原因是没有找到jakarta.websocket
。可能这是一个依赖性问题,但我不确定原因,代码在模块化之前是工作的,我希望spring-boot-starter-websocket
将把jakarta带入游戏。实际上,我也得到了客户端应用程序的类似例外。
这是我的buil.gradle
:
plugins {
id 'java'
id 'org.springframework.boot' version '3.0.2'
id 'io.spring.dependency-management' version '1.1.0'
}
repositories {
mavenCentral()
}
dependencies {
implementation 'org.springframework.boot:spring-boot-starter-websocket:3.0.2'
implementation 'org.webjars:webjars-locator-core'
implementation 'org.webjars:sockjs-client:1.0.2'
implementation 'org.webjars:stomp-websocket:2.3.3'
implementation 'org.webjars:bootstrap:3.3.7'
implementation 'org.webjars:jquery:3.1.1-1'
testImplementation 'org.springframework.boot:spring-boot-starter-test'
implementation project(':core')
}
谢谢,任何提示都很感激!
