使用Feign调用form-data的接口问题

<div class="jb51code"><pre class="brush:java;">@Slf4j
@Configuration
public class FeignRequestIntercepter{
@Bean
@Primary
@Scope("prototype")
public Encoder multipartFormEncoder() {
return new SpringFormEncoder();
}
}
</pre></div>
<p class="maodian"></p><h2>2.在Feign类上</h2>
<p>加入转换器配置</p>
<div class="jb51code"><pre class="brush:java;">@FeignClient(value = "Student",configuration = {FeignRequestIntercepter.class})
public interface StudentFeignClient {...}
</pre></div>
<p class="maodian"></p><h2>3.在Feign定义得方法中</h2>
<p>定义接口</p>
<div class="jb51code"><pre class="brush:java;">@PostMapping("/innerScore/viewScoreRemark")
Response viewScoreRemark(JSONObject json);
</pre></div>
<p>如果是多参数，则添加<strong>@RequestParam</strong>注解声明变量</p>
<div class="jb51code"><pre class="brush:java;">@PostMapping("/innerScore/viewScoreRemark")
Response viewScoreRemark(@RequestParam Long classId, @RequestParam Long studentId);
</pre></div>
<p>否则报错</p>
<blockquote><p>Caused by: java.lang.IllegalStateException: Method has too many Body parameters: public abstract com.iqiyi.nexus.dto.Response xxx.viewScoreRemark(java.lang.Long,java.lang.Long)</p></blockquote>
<p class="maodian"></p><h2>4.总结</h2>
<p>以上为个人经验，希望能给大家一个参考，也希望大家多多支持琼殿技术社区。</p>
