feign传递map

在使用Feign进行请求时，如果需要传递Map参数，可以通过以下方式解决。首先，在Feign的配置类中注入SpringFormEncoder来支持Map传参时的表单参数编码。具体代码如下：

@Configuration
public class FeignConfig {
    @Bean
    public Encoder feignFormEncoder(ObjectFactory<HttpMessageConverters> converters) {
        return new SpringFormEncoder(new SpringEncoder(converters));
    }
}

然后，在Feign接口的方法上添加`consumes="application/x-www-form-urlencoded"`注解，并将参数声明为`@RequestBody Map<String, ?>`。示例代码如下：

@PostMapping(value = "/feign/sayHelloWithMap", consumes = "application/x-www-form-urlencoded")
String sayHelloWithMap(@RequestBody Map<String, ?> map);

这样就可以通过Feign传递Map参数了。\[1\]
