我尝试使用Vaadin 7.7.0进行Spring启动。默认情况下,如果我没有指定,则spring boot使用tomcat。但是,我发现有一个日志如下:
2016-08-26 12:08:49.897 INFO 3240 --- [ main] e.j.JettyEmbeddedServletContainerFactory : Server initialized with port: 8080
2016-08-26 12:08:49.900 INFO 3240 --- [ main] org.eclipse.jetty.server.Server : jetty-8.y.z-SNAPSHOT
我通过eclipse检查依赖关系并且没有码头。
以下是问题的依赖关系
如此强大的版本怎么来?
<dependency>

<artifactId>vaadin-client-compiler</artifactId>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>com.vaadin</groupId>
<artifactId>vaadin-push</artifactId>
</dependency>
经过删除检查后发现错误的码头来自
<dependency>
<groupId>com.vaadin</groupId>
<artifactId>vaadin-client-compiler</artifactId>
<scope>provided</scope>
</dependency>
删除后可以添加
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<scope>provided</scope>
</dependency>
一切正常。
我不知道这个包裹发生了什么。是否存在依赖性冲突?
答案 0 :(得分:2)
Jetty用于Vaadin的Push功能,已经包含在内。
