java自定义404返回，因为spring 包装的没有code，所以需要自定义返回，spring会在404自动重定向ip:port/error的url

package com.itranswarp.crypto.web.api.v1;

import com.itranswarp.crypto.ApiError;
import com.itranswarp.crypto.bean.ResponseWrapper;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

      ResponseWrapper responseWrapper = new ResponseWrapper();
      responseWrapper.setStatus(ResponseWrapper.STATUS_FAIL);
      responseWrapper.setCode(ApiError.PATH_NOT_FOUND.name());
      responseWrapper.setData("");
