FactoryBean threw exception on object creation; nested exception is java.lang.IllegalStateException: PathVariable annotation was empty on param 0.

@FeignClient(value = "DAILY-SERVICE", fallback = DailyFallback.class)
public interface DailyFeign {

    @GetMapping("query")
    ResponseEntity query(Daily daily);

    @GetMapping("discovery/{appName}")
    Object discovery(@PathVariable String appName);

    @GetMapping("lb")
    String lbReceive();
}

 

使用feign时，如果参数中带有@PathVariable则需要使用value显示指明参数名

    @GetMapping("discovery/{appName}")
    Object discovery(@PathVariable(value = "appName") String appName);
