Using spring cloud feign when http code is 401, the respose.body() is null

Question

Using the spring cloud feign call my service, when the service return 401 exception, the respose.body() is null.

When I throw the exception that is throw new BadRequestException(400， “this http code is 400”); I can get the error message that this http code is 400 by response.body(). But when I throw the exception throw new BadRequestException(401， “this http code is 401”);, the response.body() is null. This response is feign.Response.

Why I can`t get this error message when http code is 401?

Hope your help! Thank you very much!

Switch to feign-okhttp will fix your problem.

Add in Pom:

<dependency>
    <groupId>com.netflix.feign</groupId>
    <artifactId>feign-okhttp</artifactId>
    <version>8.18.0</version>
</dependency>

And add in your config:

feign.okhttp.enabled: true
