openFeign调用接口时传递表单参数、Json参数、HttpServletRequest对象

openFeign调用接口时传递Json参数以及httpservletrequest对象

一、控制器

@RestController
@RequestMapping("test")
public class TestController {/*** 用来测试表单参数传递：单个参数*/@PostMapping(value = "/formDataTest")public Object formDataTest(@RequestParam String id) {......}/*** 用来测试表单参数传递：多个参数*/@PostMapping(value = "/formDataTest2")public Object formDataTest2(@RequestParam String id, @RequestParam String name) {......}/*** 用来测试Json参数传递*/@PostMapping(value = "/jsonTest")public Object jsonTest(@RequestBody JsonTestParam param) {......}/*** 用来测试HttpServletRequest参数传递*/@PostMapping(value = "/httpServletRequest_Test")public Object httpServletRequest_Test(HttpServletRequest request) {......}
}

二、Feign客户端

@FeignClient(name = "defaultXXX-cloud", contextId = "XXXClient", path = "defaultXXXPath")
@RefreshScope
public interface XXXFeignClient {/*** 传递表单参数：单个参数*/@PostMapping(value = "/test/formDataTest")Object formDataTest(String id);/*** 传递表单参数：多个参数，需要使用@RequestParam并指定name属性，否则会报错*/@PostMapping(value = "/test/formDataTest2")Object formDataTest2(@RequestParam(name = "id") String id, @RequestParam(name = "name") String name);/*** 传递JSON参数方式一：指定：consumes = "application/json"*/@PostMapping(value = "/test/jsonTest", consumes = "application/json")Object jsonTest(JsonTestParam param);/*** 传递JSON参数方式二：使用@RequestBody*/@PostMapping(value = "/test/jsonTest")Object jsonTest(@RequestBody JsonTestParam param);/*** 传递HttpServletRequest：不需要传递，直接调用即可*/@PostMapping(value = "/test/httpServletRequest_Test")Object httpServletRequest_Test();}
