feignclient发送get请求,传递参数为对象。此时不能使用在地址栏传递参数的方式,需要将参数放到请求体中。
修改application.yml中配置feign发送请求使用apache httpclient 而不是默认的jdk UrlConnection
feign.httpclient.enabled= true
pom.xml中增加对apache httpclient的支持。
<!-- 配置feign 发送请求使用 httpclient,而不是java原生 --> <dependency> <groupId>org.apache.httpcomponents</groupId> <artifactId>httpclient</artifactId> </dependency> <!-- 使用Apache HttpClient替换Feign原生httpclient --> <dependency> <groupId>com.netflix.feign</groupId> <artifactId>feign-httpclient</artifactId> <version>8.15.1</version> </dependency>
在ApacheHttpClient中看到默认设置的Content-Type是ContentType.DEFAULT_TEXT,即text/plain; charset=ISO-8859-1, 此时传递对象需要配置为application/json
@FeignClient(name="feign-consumer") public interface ServiceClient { /**@param user * @return */ @RequestMapping(method = RequestMethod.GET, value = "/test4",consumes="application/json") String getInstanceInfo4(User user); }
/**Feign发送Get请求时用对象传递参数 * @param servers * @return */ @RequestMapping(value="/test4", method = RequestMethod.GET,consumes="application/json") public String firstDemo4(@RequestBody User u) { System.out.println(u); return "hello3"+u; }

上手,运行。。。报错:Caused by: java.lang.NoSuchMethodError: feign.Response.create(ILjava/lang/String;Ljava/util/Map;Lfeign/Response$Body;)Lfeign/Response;
参考 https://ask.csdn.net/questions/773444 这个问答,得知需要修改依赖版本
<dependency> <groupId>io.github.openfeign</groupId> <artifactId>feign-httpclient</artifactId> <version>10.1.0</version> </dependency>
完美解决
