1, the new UserFeignClientFallbackFactory class that implements the interface FallbackFactory, rewrite create interfaces:
@Component
public class UserFeignClientFallackFactory implements FallbackFactory<UserFeignClient> {
private static final Logger LOGGER = LoggerFactory.getLogger(UserFeignClientFallackFactory.class);
@Override
public UserFeignClient create(Throwable throwable) {
return new UserFeignClient() {
@Override
public Map findById(Integer userId) {
UserFeignClientFallackFactory.LOGGER.info("===================fallback;reason was:",throwable);
Map<String, String> user = new HashMap<>(3);
user.put ( "name", "default user");
user.put("id","-1");
user.put("age","18");
return user;
}
};
}
}
2, modify FeignClient categories:
@FeignClient(name = "user",fallbackFactory = UserFeignClientFallackFactory.class)
public interface UserFeignClient {
@RequestMapping(value = "/user/getUserInfo", method = RequestMethod.GET)
Map findById(@RequestParam("userId") Integer userId);
}
Use @FeignClient of fallbackFactory property is set fallback logic.
3, the same test results.
