springboot-web在访问的时，全局增加访问前缀，需要自定义配置。如果使用webmvc需要实现
WebMvcConfigurer的配置类并实现configurePathMatch方法，如果使用webfulx需要继承WebFluxConfigurer并实现configurePathMatching方式。

1.全局配置

1.1 webmvc下配置

import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.PathMatchConfigurer;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;

@Configuration
public class MyWebConnfig implements WebMvcConfigurer {
    @Override
    public void configurePathMatch(PathMatchConfigurer configurer) {
        configurer.addPathPrefix("/api/v1", c -> true);
    }
}

2.2 webfulx下配置

import org.springframework.context.annotation.Configuration;
import org.springframework.web.reactive.config.PathMatchConfigurer;
import org.springframework.web.reactive.config.WebFluxConfigurer;

@Configuration
public class MyWebConnfig implements WebFluxConfigurer {
    @Override
    public void configurePathMatching(PathMatchConfigurer configurer) {
        configurer.addPathPrefix("/api/v1", c -> true);
    }
}

2.局部配置（只修改部分）

2.1 自定义注解

@Target(ElementType.TYPE)
@Retention(RetentionPolicy.RUNTIME)
@RestController
@RequestMapping(produces = MediaType.APPLICATION_JSON_VALUE)
public @interface ApiController {
    @AliasFor(annotation = RequestMapping.class)
    String name() default "";

    @AliasFor(annotation = RequestMapping.class)
    String[] value() default {};

    @AliasFor(annotation = RequestMapping.class)
    String[] path() default {};
}

2.2controller上增加注解使用

@ApiController("hello")
public class HelloController {

    @GetMapping("info")
    public String helloSay() {
        return "hello say hello;";
    }
}

2.2修改WebMvcConfigurer配置

@Configuration
public class MyWebConnfig implements WebMvcConfigurer {
//    @Override
//    public void configurePathMatch(PathMatchConfigurer configurer) {
//        configurer.addPathPrefix("/api", c -> true);
//    }

    @Override
    public void configurePathMatch(PathMatchConfigurer configurer) {
        configurer.addPathPrefix("/api/v1", cls -> cls.isAnnotationPresent(ApiController.class));
    }
}
