Question

从ACTUATOR（/ Refresh）刷新spring boot云应用程序时出现以下异常。它运行在独立的tomcat服务器上。它使用的是SpringBootServletInitializer。：

constructor (@Inject(DOCUMENT) private document: any, private titleService: Title){

    /**
     * get the <head> Element
     * @type {any}
     */
    this.dom = document;

    this.headElement = this.dom.getSelection('head');
    this.metaDescription = this.getOrCreateMetaElement('description');
    this.robots = this.getOrCreateMetaElement('robots');
}

Spring Boot Cloud ACTUATOR / restart endpoint：例外：当上下文已初始化时，无法将过滤器添加到上下文/ ROOT

以下4个过滤器产生了问题：errorPageFilter，metricsFilter，webRequestLoggingFilter，applicationContextIdFilter

以下是解决方案：

public class XXXSpringBootServletInitializer  extends SpringBootServletInitializer {
     @Override
     public WebApplicationContext createRootApplicationContext(ServletContext servletContext) {
          // Disable errorPageFilter
          setRegisterErrorPageFilter(false);
          // Disable metricsFilter
          System.setProperty("endpoints.metrics.filter.enabled", "false");
          // Disable applicationContextIdFilter
          System.setProperty("management.addApplicationContextHeader", "false");
          WebApplicationContext oWebApplicationContext = super.createRootApplicationContext(servletContext);    
          return oWebApplicationContext;
     }
}

禁用webRequestLoggingFilter：

@SpringBootApplication(exclude={TraceWebFilterAutoConfiguration.class})
public class SIGBootApplication {
    ........
}

Spring Boot Cloud ACTUATOR /刷新端点：例外：由于上下文已初始化，因此无法将过滤器添加到上下文/ ROOT
