How do I tell Spring Boot to ignore Jetty and always use Tomcat?
提问by MarSik
I have the following setup:
我有以下设置：
spring-boot application (using embedded tomcat)
spring-date-neo4j (embedded mode)
spring-websockets
and neo4j-browser included using (the goal is to be able to use REST and web browser to debug embedded database):
和 neo4j-browser 包含使用（目标是能够使用 REST 和 Web 浏览器来调试嵌入式数据库）：
<dependency>
<groupId>org.neo4j.app</groupId>

And started using:
并开始使用：
@Autowired
@Bean(destroyMethod = "shutdown")
public GraphDatabaseService graphDatabaseService(DatabaseConfiguration dbConf) {
// removed with every maven clear
return new GraphDatabaseFactory().newEmbeddedDatabase(dbConf.getDbPath());
// stays after clear
//return new EmbeddedGraphDatabase("./data/neo4j.db");
}
@Bean(destroyMethod = "stop")
public WrappingNeoServerBootstrapper serverWrapper(GraphDatabaseService db) {
WrappingNeoServerBootstrapper wrapper = new WrappingNeoServerBootstrapper((GraphDatabaseAPI)db);
wrapper.start();
return wrapper;
}
And spring boot is insisting on trying Jetty as the servlet container even with the following config annotations for the main app class:
即使使用以下主应用程序类的配置注释，spring boot 仍坚持尝试将 Jetty 作为 servlet 容器：
@EnableAutoConfiguration(exclude = EmbeddedServletContainerAutoConfiguration.EmbeddedJetty.class)
@ComponentScan
@EnableWebMvc
@Configuration
public class WebApplication extends WebMvcConfigurerAdapter {
But the jetty version Spring uses (8) does not support web sockets so I am getting
但是 Spring 使用的码头版本 (8) 不支持网络套接字，所以我得到了
Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean
with name 'jettyEmbeddedServletContainerFactory' defined in class path resource
[org/springframework/boot/autoconfigure/web/EmbeddedServletContainerAutoConfiguration$EmbeddedJetty.class]:
Initialization of bean failed; nested exception is java.lang.IllegalStateException:
Websockets are currently only supported in Tomcat (found class org.springframework.boot.context.embedded.jetty.JettyEmbeddedServletContainerFactory).
How do I tell Spring Boot to ignore Jetty and always use Tomcat?

Boot's using Jetty as it's on the classpath. The attempt to exclude it by excluding EmbeddedServletContainerAutoConfiguration.EmbeddedJetty.classdoesn't work as EmdeddedJettyisn't an auto-configuration class. EmbeddedServletContainerAutoConfigurationis an auto-configuration class and you could exclude it, but then you'd also lose embedded Tomcat support which I don't think is what you want. The easiest thing to do is to eliminate Jetty from your application's classpath.
Boot 使用 Jetty，因为它在类路径上。通过排除来排除它的尝试EmbeddedServletContainerAutoConfiguration.EmbeddedJetty.class不起作用，因为EmdeddedJetty它不是自动配置类。EmbeddedServletContainerAutoConfiguration是一个自动配置类，你可以排除它，但是你也会失去嵌入式 Tomcat 支持，我认为这不是你想要的。最简单的方法是从应用程序的类路径中消除 Jetty。
The dependency tree output shows that you've still got transitive dependencies on org.eclipse.jetty:jetty-serverand org.eclipse.jetty:jetty-webapp, both of which are being pulled in by your direct dependency on org.neo4j.app:neo4j-server. Update your pom to exclude them:
依赖树输出显示，你仍然有上传递依赖org.eclipse.jetty:jetty-server和org.eclipse.jetty:jetty-webapp，这两者都正在由您的直接依赖关系拉org.neo4j.app:neo4j-server。更新您的 pom 以排除它们：
<dependency>
<groupId>org.neo4j.app</groupId>
<artifactId>neo4j-server</artifactId>
<version>${neo4j.version}</version>
<classifier>static-web</classifier>
<exclusions>
<exclusion>
<groupId>ch.qos.logback</groupId>
<artifactId>logback-classic</artifactId>
</exclusion>
<exclusion>
<groupId>ch.qos.logback</groupId>
<artifactId>logback-access</artifactId>
</exclusion>
<exclusion>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
</exclusion>
<exclusion>
<artifactId>javax.servlet</artifactId>
<groupId>org.eclipse.jetty.orbit</groupId>
</exclusion>
<exclusion>
<groupId>org.eclipse.jetty</groupId>
<artifactId>jetty-server</artifactId>
</exclusion>
<exclusion>
<groupId>org.eclipse.jetty</groupId>
<artifactId>jetty-webapp</artifactId>
</exclusion>
</exclusions>
</dependency>
Update:if excluding Jetty from the dependencies isn't an option, then you can declare your own TomcatEmbeddedServletContainerFactorybean:
更新：如果不能从依赖项中排除 Jetty，那么您可以声明自己的TomcatEmbeddedServletContainerFactorybean：
@Bean
public TomcatEmbeddedServletContainerFactory tomcatEmbeddedServletContainerFactory() {
return new TomcatEmbeddedServletContainerFactory();
}
This will prevent the auto-configuration of the embedded Jetty server as it's conditional on there being no EmbeddedServletContainerFactorybean in the application context.
这将阻止嵌入式 Jetty 服务器的自动配置，因为它EmbeddedServletContainerFactory以应用程序上下文中没有bean为条件。
回答by Franti?ek Hartman
You could also import the EmbeddedTomcatconfiguration directly. Has the same effect as declaring TomcatEmbeddedServletContainerFactorydirectly and should there be any change with it you won't need to update anything.
您也可以EmbeddedTomcat直接导入配置。与TomcatEmbeddedServletContainerFactory直接声明的效果相同，如果有任何更改，则无需更新任何内容。
@SpringBootApplication
@Import(EmbeddedServletContainerAutoConfiguration.EmbeddedTomcat.class)
... your configuration class
