使用openfeign遇到一个简单错误:


Caused by: java.net.URISyntaxException: Illegal character in path at index 32: http://test-service/v1/tests/py/{pid}
	at java.net.URI$Parser.fail(URI.java:2848) ~[?:1.8.0_181]

从错误上看,这只是一个非法的url造成的,但是实际检查发现,根本原因不是这个,我有一个commonservice需要调用testservice,调用代码:

@GetMapping(value= "v1/tests/py/{pid}")
    Message<List<PPyVO>> getPPy(@PathVariable("pid") Long pid);

发现调用这个接口的时候,传递的参数是null,原来我认为就算是null也应该把{pid}给替换掉,但是实际上并不会,所以产生了这个问题。
