如何重写Spring Boot RequestMappingHandlerMapping？

import org.springframework.web.servlet.mvc.method.RequestMappingInfo;
import org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping;

public class CustomRequestMappingHandlerMapping extends RequestMappingHandlerMapping {
    // 重写方法
}

import org.springframework.web.method.HandlerMethod;
import org.springframework.web.servlet.mvc.condition.RequestCondition;
import org.springframework.web.servlet.mvc.method.RequestMappingInfo;
import org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping;

public class CustomRequestMappingHandlerMapping extends RequestMappingHandlerMapping {

    @Override
    protected RequestMappingInfo getMappingForMethod(Method method, Class<?> handlerType) {
        // 自定义映射规则
        // 返回一个RequestMappingInfo对象
    }
}

import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurationSupport;

@Configuration
public class WebMvcConfig extends WebMvcConfigurationSupport {

    @Override
    protected RequestMappingHandlerMapping createRequestMappingHandlerMapping() {
        return new CustomRequestMappingHandlerMapping();
    }
}
