springboot 怎么实现接口灰度发布

引用中提到了使用Spring Boot和Apollo客户端连接依赖来实现接口灰度发布。您需要添加以下依赖到您的项目中：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
    <version>2.2.1.RELEASE</version>
</dependency>
<dependency>
    <groupId>com.ctrip.framework.apollo</groupId>
    <artifactId>apollo-client</artifactId>
    <version>1.5.1</version>
</dependency>

然后，您需要将拦截器注册到Spring容器中，可以通过创建一个带有@Configuration注解的类，并将GrayFeigeInterceptor添加到@Bean注解的方法中。这样就可以将拦截器注册到Spring容器中了。示例代码如下：

@Configuration
@ConditionalOnWebApplication(type = ConditionalOnWebApplication.Type.SERVLET)
@ConditionalOnProperty(name = "gray.rule.enabled", matchIfMissing = true, havingValue = "true")
@AutoConfigureAfter(XlcpGrayAutoConfiguration.class)
public class GrayFeignAutoConfiguration {
    @Bean
    public GrayFeigeInterceptor grayFeigeInterceptor(){
        return new GrayFeigeInterceptor();
    }
}

接下来，您需要自定义ApiVersionHandleMapping来注册自定义的接口版本处理映射。您可以创建一个实现了WebMvcRegistrations接口的类，并重写getRequestMappingHandlerMapping()方法返回ApiVersionHandleMapping实例。示例代码如下：

import org.springframework.boot.autoconfigure.web.servlet.WebMvcRegistrations;
import org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping;

public class ApiVersionMappingRegister implements WebMvcRegistrations {
    @Override
    public RequestMappingHandlerMapping getRequestMappingHandlerMapping() {
        return new ApiVersionHandleMapping();
    }
}

最后，需要将自定义的ApiVersionMappingRegister注册到Spring容器中。可以创建一个带有@Configuration注解的类，并在该类中使用@Bean注解的方法返回ApiVersionMappingRegister实例。示例代码如下：

import org.springframework.boot.autoconfigure.web.servlet.WebMvcRegistrations;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class BaseConfiguration {
    @Bean
    public WebMvcRegistrations getWebMvcRegistrations(){
        return new ApiVersionMappingRegister();
    }
}

通过以上步骤，您就可以实现接口灰度发布了。请根据您的实际需求进行相应的配置和调整。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
