不同端口上的Spring 2.1.0管理服务器端口

Question

在我的spring 2.0应用程序中，我让主应用程序监听端口1234，我想让管理服务器在1235上运行。

因此，在我的配置文件中，我设置：

management.server.port=1235

由于以下错误，我的服务器无法启动：

错误2018-11-1405:20:14.958主SpringApplication -应用程序运行失败的org.springframework.beans.FatalBeanException: ServletWebServerFactory实现com.my.MyApplication$2无法实例化.若要允许使用单独的管理端口，应该在org.springframework.boot.actuate.autoconfigure.web.servlet.ServletManagementContextFactory.determineServletWebServerFactoryClass(ServletManagementContextFactory.java:77) ~spring-boot-actuator-autoconfigure-2.1.0.RELEASE.jar:2.1.0.RELEASE at org.springframework.boot.actuate.autoconfigure.web.servlet.ServletManagementContextFactory.registerServletWebServerFactory(ServletManagementContextFactory.java:64) ~spring-boot-actuator-autoconfigure-2.1.0.RELEASE.jar:2.1.0.RELEASE上使用顶级类或静态内部类。在org.springframework.boot.actuate.autoconfigure.web.servlet.ServletManagementContextFactory.createManagementContext(ServletManagementContextFactory.java:52) ~spring-boot-actuator-autoconfigure-2.1.0.RELEASE.jar:2.1.0.RELEASE at org.springframework.boot.actuate.autoconfigure.web.server.ManagementContextAutoConfiguration$DifferentManagementContextConfiguration.afterSingletonsInstantiated(ManagementContextAutoConfiguration.java:143) ~spring-boot-actuator-autoconfigure-2.1.0.RELEASE.jar:2.1.0.RELEASE at org.springframework.beans.factory.support.DefaultListableBeanFactory.preInstantiateSingletons(DefaultListableBeanFactory.java:863) ~spring 5.1.2.RELEASE.jar:5.1.2.在org.springframework.context.support.AbstractApplicationContext.finishBeanFactoryInitialization(AbstractApplicationContext.java:863) ~spring-context-5.1.2.RELEASE.jar:5.1.2.RELEASE at org.springframework.context.support.AbstractApplicationContext.refresh(AbstractApplicationContext.java:546) ~spring-context-5.1.2.RELEASE.jar:5.1.2.RELEASE atRELEASE.jar:2.1.0.RELEASE.jar: org.springframework.boot.web.servlet.context.ServletWebServerApplicationContext.refresh(ServletWebServerApplicationContext.java:140) -2.1.0.RELEASE.JAR:2.1.0.RELEASE.JAR:2。1.0. org.springframework.boot.SpringApplication.run(SpringApplication.java:316)弹簧的1.0.RELEASE 2.1.0.RELEASE.jar:2.1.0.在org.springframework.boot.SpringApplication.run(SpringApplication.java:1260)弹簧-2.1.0 RELEASE.jar:2.1.0在org.springframework.boot.SpringApplication.run(SpringApplication.java:1248)弹簧-在org.springframework.boot.SpringApplication.run(SpringApplication.java:1248)弹簧-启动-2.1.0 RELEASE.jar2.1.0. com.my.MyApplication.main(EmsApplication.java:51) main/:？

如果我移除这个：

@Bean
public TomcatServletWebServerFactory containerFactory() {
    return new TomcatServletWebServerFactory() {
        @Override
        protected void customizeConnector(Connector connector) {
            int maxSize = 50000000;
            super.customizeConnector(connector);
            connector.setMaxPostSize(maxSize);
            connector.setMaxSavePostSize(maxSize);
            if (connector.getProtocolHandler() instanceof AbstractHttp11Protocol) {

                ((AbstractHttp11Protocol <?>) connector.getProtocolHandler()).setMaxSwallowSize(maxSize);
            }
        }
        t
    };

}

那就成功了。

如何解决这个问题？

谢谢!

Answer 1

您的TomcatWebServerFactory子类是一个匿名内部类。它需要是静态内部类或顶级类，以便能够实例化：

@Bean
public TomcatServletWebServerFactory containerFactory() {
    return new CustomTomcatServletWebServerFactory();
}

static final class CustomTomcatServletWebServerFactory
        extends TomcatServletWebServerFactory {

    @Override
    protected void customizeConnector(Connector connector) {
        int maxSize = 50000000;
        super.customizeConnector(connector);
        connector.setMaxPostSize(maxSize);
        connector.setMaxSavePostSize(maxSize);
        if (connector.getProtocolHandler() instanceof AbstractHttp11Protocol) {
            ((AbstractHttp11Protocol<?>) connector.getProtocolHandler())
                    .setMaxSwallowSize(maxSize);
        }
    }

}

或者，您可以使用自定义程序而不是子类TomcatServletWebServerFactory。

@Bean
public WebServerFactoryCustomizer<TomcatServletWebServerFactory> tomcatCustomizer() {
    return (tomcat) -> tomcat.addConnectorCustomizers((connector) -> {
        int maxSize = 50000000;
        connector.setMaxPostSize(maxSize);
        connector.setMaxSavePostSize(maxSize);
        if (connector.getProtocolHandler() instanceof AbstractHttp11Protocol) {

            ((AbstractHttp11Protocol<?>) connector.getProtocolHandler())
                    .setMaxSwallowSize(maxSize);
        }
    });
}
