即使我使用tomcat，带有vaadin的Spring Boot也会运行码头 [英] Spring boot with vaadin run jetty even though I use tomcat

问题描述

我尝试在Vaadin 7.7.0中使用Spring Boot.默认情况下，如果我未指定，spring boot使用tomcat.但是，我发现有如下日志:

I try to use Spring boot with Vaadin 7.7.0. By default, spring boot use tomcat if I don not specify. However, I found there is a log as below:

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

我通过日食检查了依存关系，没有码头.

I check the dependency through eclipse and there is no jetty.

这是问题的依赖项

如此强大的版本怎么会出现?

How could a such strong version come?

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-jdbc</artifactId>

    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-configuration-processor</artifactId>
    <optional>true</optional>
</dependency>
<dependency>
    <groupId>com.vaadin</groupId>
    <artifactId>vaadin-spring-boot-starter</artifactId>
    <version>1.0.0</version>

<dependency>
    <groupId>com.vaadin</groupId>
    <artifactId>vaadin-client</artifactId>
</dependency>
<dependency>

    <artifactId>vaadin-client-compiler</artifactId>
    <scope>provided</scope>
</dependency>
<dependency>
    <groupId>com.vaadin</groupId>
    <artifactId>vaadin-push</artifactId>
</dependency>

通过移除检查后，我发现错误的码头来自

After checking by remove I found that the wrong jetty comes from

<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.

我不知道这个包裹怎么了.有依赖性冲突吗?

I don't know what happened to this package. Is it any dependency conflict?

推荐答案

Jetty用于Vaadin的Push功能，并且已经包括在内.

Jetty is used for the Push feature of Vaadin and is already included.
