我正在尝试运行一个 Spring Boot 项目,该项目在嵌入式 Tomcat 上完美运行,但部署到 Wildfly 21.x 时会抛出 java.lang.NoClassDefFoundError: org/apache/catalina/connector/Connector
如有任何帮助,我们将不胜感激。
下面是我的代码片段。
主文件:-
import org.apache.catalina.connector.Connector;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.embedded.tomcat.TomcatServletWebServerFactory;
import org.springframework.boot.web.servlet.server.ServletWebServerFactory;
import org.springframework.context.annotation.Bean;
@SpringBootApplication
public class CdPlaylistadapterApplication {
@Value("${http.port}")
private int httpPort;
public static void main(String[] args) {
SpringApplication.run(CdPlaylistadapterApplication.class, args);
}
@Bean
public ServletWebServerFactory servletContainer() {
TomcatServletWebServerFactory tomcat = new TomcatServletWebServerFactory();
tomcat.addAdditionalTomcatConnectors(createStandardConnector());
return tomcat;
}
private Connector createStandardConnector() {
Connector connector = new Connector("org.apache.coyote.http11.Http11NioProtocol");
connector.setPort(httpPort);
return connector;
}
}
我的 pom.xml 片段

最佳答案
类org.apache.catalina.connector.Connector
是Tomcat的一部分。为了使您的应用程序能够在外部 servlet 容器上正常工作,Tomcat 的嵌入式副本不得位于 Web 应用程序的类路径上(即在 /WEB-INF/lib
)。您可以通过将 spring-boot-starter-tomcat
的范围设置为 provided
来正确设置它。
但是现在您遇到了问题,因为 CdPlaylistadapterApplication
在其方法签名之一中具有 Connector
,并且 Spring Boot 在创建 CdPlaylistadapterApplication< 的实例时失败
类。
要解决这个问题,您需要将 Tomcat 特定配置移动到另一个类(甚至是嵌套的),并使用 @ConditionalOnClass
注释保护它:
@SpringBootApplication
public class CdPlaylistadapterApplication extends SpringBootServletInitializer {
@Configuration
@ConditionalOnClass({Servlet.class, Tomcat.class, UpgradeProtocol.class})
static class EmbeddedConfiguration {
@Value("${http.port}")
private int httpPort;
@Bean
public ServletWebServerFactory servletContainer() {
TomcatServletWebServerFactory tomcat = new TomcatServletWebServerFactory();
tomcat.addAdditionalTomcatConnectors(createStandardConnector());
return tomcat;
}
private Connector createStandardConnector() {
Connector connector = new Connector("org.apache.coyote.http11.Http11NioProtocol");
connector.setPort(httpPort);
return connector;
}
}
public static void main(String[] args) {
SpringApplication.run(CdPlaylistadapterApplication.class, args);
}
}
