无论如何在spring4中禁用注释? [英] Are there anyway to disable annotation in spring4?

问题描述

我有一个问题，也许很简单，但是我找不到解决方法.

I have a question, maybe simple, but I can not find out the solution.

我使用的是Spring Boot，并在代码中添加了一些注释，如下所示:

I am using spring boot and added some annotation to the code like this:

@EnableEurekaClient
@SpringBootApplication
@EnableCaching
public class MyApplication {
    public static void main(String[] args) {
        SpringApplication.run(MyApplication.class, args);
    }
}

但是在某些其他环境中，例如在生产环境中，我们想要删除EurekaClient，但是我不想为每个环境手动删除它，而是希望使用环境变量或命令行参数来控制行为.我想这样做:

But in some other environment, for example, in production environment, we want to remove EurekaClient, but I do not want to manually remove it manually for each environment, instead, I want to use environment variable or command line parameter to control the behavior. I suppose to do this way:

@EnableEurekaClient(Enabled = {EnableEureka})
@SpringBootApplication
@EnableCaching
public class MyApplication {
        public static void main(String[] args) {
            SpringApplication.run(MyApplication.class, args);
        }
}

然后，我可以轻松启动该应用程序，而无需触摸代码.

Then I can easily start this application without touching the code.

有人可以告诉我这是否可行吗?如果是这样，我该怎么办?

Can anyone tell me if this is possible? If so, how can I do it?

谢谢

推荐答案

您希望使用.然后，在启动应用程序时，可以为生产环境以外的环境设置 -Dspring.profiles.active = eureka-client .

You would want to work with Spring Boot Profiles. Split out the @EnableEurekaClient to another @Configuration class and also add an @Profile("eureka-client") to the class. Then when starting up the application you can set a -Dspring.profiles.active=eureka-client for the environments other than production.

示例:

@SpringBootApplication
@EnableCaching
public class MyApplication {
    public static void main(String[] args) {
        SpringApplication.run(MyApplication.class, args);
    }
}

@Configuration
@EnableEurekaClient
@Profile("eureka-client")
public class EurekaClientConfiguration {
}
