我有一个简单的Spring Boot应用程序,使用org.apache.commons.dbcp2.BasicDataSource作为dataSource bean.

Spring引导自动将数据源公开为MBean.

bean声明:

@Bean
public DataSource dataSource() {
    BasicDataSource dataSource = new BasicDataSource();
    dataSource.setUrl(dbUrl);
    dataSource.setDriverClassName(jdbcDriver);
    dataSource.setUsername(dbUserName);
    dataSource.setPassword(dbPassword);
    return dataSource;
}

一切正常.但是,我在关闭应用程序时看到错误.只有在运行可执行jar时才会出现此错误.使用Gradle Spring插件(gradle bootRun)时,不会显示.

我想知道,1.这个bean如何作为JMX MBean公开？2.如何正确注销这个MBean？

简单地说,让我通过一个例子来解释.

<?php
class My extends Thread {
    public function run() {
        /** ... **/
    }
}
$my = new My();
var_dump($my->start());
?>

这是来自PHP手册.

我想知道是否有办法以更像Java的方式做到这一点.例如:

<?php
$my = new Thread(){
        public function run() {
            /** ... **/
        }
      };
var_dump($my->start());
?>

我知道许多类似的问题已在这里发布并回答,但它们与我所遇到的完全不同.

我有一个Lambda函数来处理传入的请求(GET和POST).我还设置了一个api网关作为面向公众的端点.此外,我在为API主机名设置自定义域名后设置了自定义域

测试调用适用于lambda和api网关控制台.一切也可以使用调用URL,但不能使用我设置的自定义域.

以下是一些更多细节:

调用URL(Works):

https://{api gateway id}.execute-api.us-west-2.amazonaws.com/prod/endpoint

自定义域endpint(不起作用):

https://api.{my domain}.com/endpoint

基本路径映射:

/endpoint   endpoint:prod

所有方法验证:

Authorization None
API Key Not required

Route53:

A record as alias that points api.{my domain}.com to the cloudfront distribution domain name as alias target. 

如果有人知道这里会发生什么,我真的很感激.
