在加载@Configuration类之前加载环境属性？

Question

我在配置SSL相关env时遇到问题。我的SpringBoot应用程序中的属性。以下是属性

server.ssl.key-store=XXXX
server.ssl.key-password=XXXX
server.ssl.trust-store=XXXX

ActiveMQ使用以上属性来保护连接。以下是示例代码

    @Bean
    public ActiveMQConnectionFactory connectionFactory(){
        ActiveMQConnectionFactory connectionFactory = new ActiveMQConnectionFactory();
        connectionFactory.setBrokerURL(this.brokerUrl);
        connectionFactory.setUseAsyncSend(this.useAsyncSend);
        connectionFactory.setAlwaysSessionAsync(this.alwaysSessionAsync);
        connectionFactory.setOptimizeAcknowledge(this.optimizeAcknowledge);
        connectionFactory.setUserName(this.Username);
        connectionFactory.setPassword(this.password);
        return connectionFactory;
    }

但是上面的代码无法创建SSL连接，而是以与ActiveMQ的TCP连接结束。所以我稍微改变代码来调试问题

    @Bean
    public ActiveMQConnectionFactory connectionFactory(){
        System.setProperty("javax.net.ssl.keyStore", "broker.ks");
        System.setProperty("javax.net.ssl.keyStorePassword", "XXXXX");
        System.setProperty("javax.net.ssl.trustStore", "client.ts");
        ActiveMQConnectionFactory connectionFactory = new ActiveMQConnectionFactory();
        connectionFactory.setBrokerURL(this.brokerUrl);
        connectionFactory.setUseAsyncSend(this.useAsyncSend);
        connectionFactory.setAlwaysSessionAsync(this.alwaysSessionAsync);
        connectionFactory.setOptimizeAcknowledge(this.optimizeAcknowledge);
        connectionFactory.setUserName(this.Username);
        connectionFactory.setPassword(this.password);
        return connectionFactory;
   }

然后它开始正常工作。它能够在客户端和服务器之间建立SSL连接。所以我得出结论，application.properties文件中包含的属性是在@Configuarion类加载后加载的。 所以我的查询是“是否可以在DispatchcherServlet开始加载所有配置类之前加载这些与env相关的属性？”
