Feign PathVariable annotation was empty on param 0.

Feign PathVariable annotation was empty on param 0.

使用Feign的時候,如果參數中帶有

@PathVariable形式的參數,則要用value=""标明對應的參數,否則會抛出IllegalStateException異常

如

@RequestMapping(value = “/dept/getById/{id}”, method = RequestMethod.GET)

public Dept getById(@PathVariable Long id); // wrong 錯的

–>

@RequestMapping(value = “/dept/getById/{id}”, method = RequestMethod.GET)

public Dept getById(@PathVariable(value = “id”) Long id); // right 對的
