我在使用feign发请求的时候出现json错误。。。

Question

feign的配置

feign:
  hystrix:
    enabled: false
  httpclient:
    enabled: true
  compression:
    request:
      enabled: true
      # 限制格式
      mime-types: text/xml,application/xml,application/json
      # 限制大小
      min-request-size: 2480

醉了，我在 yml给tomcat的配置上加上了gzip的压缩，然后feign再打开就会报错

• Allen #1

  光看错误看起来是返回的内容有特殊字符， Jackson无法解析了

• 提问者 阿拉斌 回复 Allen #2

  我感觉是重复压缩了，然后解压出来就是乱码了

• Allen 回复 提问者 阿拉斌 #3

  测试过么
