在使用feign使用get请求时候,如果是get请求且使用了@RequestBody参数,则接受方会认为是post请求。解决方式是不使用@RequestBody注解。使用@RequestParam
@RequestMapping(path = "{beanThiredApiName}",method = RequestMethod.GET) <T> BeanTechResponse<T> getBeanThiredFeign(@PathVariable("beanThiredApiName")String beanThiredApiName, @RequestHeader Map<String, String> headerMap, @RequestParam(required = false) Map<String, String> requestParam);
之前记录了,在使用feign 的response 时候,使用钉钉打印信息时候,如果使用了 response.body().asInputStream() ,则会出现 stream is close 的问题。这几天这个问题本地一直复现,且一直未能真正解决。
今天又重新看了github issue的一个回答:(https://github.com/OpenFeign/feign/issues/1187)
Short Answer: Use a custom Logger
Long Answer
Our InputStream
support on the Response
relies on reading the entire stream into memory then providing access to it. Since these network streams do not support marking, they can be read only once. What we provide instead is a method on the Response#isRepeatable
. This will let you know that you can read the Response
more than once.
With that said, our Logger
component has the capability you are looking for. It will log at specific points within the request lifecycle and has support for reading a Response
more than once. I recommend taking a look at our documentation and examples in SLF4JLogger

简短回答:使用自定义记录器
冗长的回答
我们对Response的InputStream支持依赖于将整个流读入内存,然后提供对它的访问。由于这些网络流不支持标记,因此只能读取一次。相反,我们提供的是响应#上的方法是可重复的。这将让您知道您可以多次阅读响应。
也就是说,我们的Logger组件具有您想要的功能。它将在请求生命周期中的特定点登录,并支持多次读取响应。我建议看一下SLF4JLogger中的文档和示例
也就是说 他们是支持这种的,但是不是默认的。然后看了response的源码。在body的实现有两种: InputStreamBody 和 ByteArrayBody
其默认实现是InputStreamBody. (client 初始化的时候)
两者的不同点就是 isRepeatable()的值,一个是true,一个是false. 看其注释
True if asInputStream() and asReader() can be called more than once.
如果可以多次调用asInputStream()和asReader(),则为True。
那么怎么把InputStreamBody 转换为 ByteArrayBody呢?
因为两个都是一个接口的实现,自己刚开始想的就是使用 属性赋值的方式。 就是new 一个对象,然后把值赋进去。 结果发现有个问题是,返回值会报异常。
今天是重新定义了Response,将response进行了赋值拷贝。并进行了转换。源码如下:
