配置扫描类

import org.glassfish.jersey.server.ResourceConfig;
import org.springframework.context.annotation.Configuration;

@Configuration
public class JerseyConfig extends ResourceConfig {

    public JerseyConfig() {
        // 设置要扫描的包路径，Jersey 会自动扫描该包及其子包下的资源类和提供器
        packages("com.example.demo.resource"); 

      
    }
}


或者下面这个

@Component
public class JerseyConfig extends ResourceConfig {

    public JerseyConfig(@Value("${jersey.scan.packages}") String scanPackages) {
        // 使用 application.properties 中配置的包路径
        packages(scanPackages);

        // 如果需要注册其他资源类或提供程序，可以在这里添加
        // 这里加入拦截器
        register(RestRequestFilter.class);
        register(RestResponseFilter.class);
    }
}

加入Rest 拦截器

@Provider
@Slf4j
public class RestRequestFilter implements ContainerRequestFilter {
    @Override
    public void filter(ContainerRequestContext requestContext) {

        UriInfo uriInfo = requestContext.getUriInfo();
        log.info("Rest Filter Url:{}",uriInfo.getAbsolutePath());
    }
}


@Provider
public class RestResponseFilter implements ContainerResponseFilter {
    @Override
    public void filter(ContainerRequestContext requestContext,
                       ContainerResponseContext responseContext) {

        responseContext.getHeaders().add("Access-Control-Allow-Origin", "*");
        responseContext.getHeaders().add("Access-Control-Allow-Methods", "GET, POST, PUT, DELETE");
        responseContext.getHeaders().add("Access-Control-Allow-Headers", "Content-Type, Authorization");

    }
}
