Feign support pojo object in get query method

FeignWithPojoObjectQuery.md

I use openfeign with org.springframework.cloud:spring-cloud-starter-openfeign:2+

@Autowired(required = false)
private ConversionService feignConversionService;

@Bean
public Contract feignContract() {
  return new SpringMvcPojoObjectQueryContract(this.parameterProcessors, feignConversionService);
}

import feign.MethodMetadata;
import java.lang.annotation.Annotation;
import java.util.List;
import org.apache.commons.lang3.StringUtils;
import org.springframework.cloud.openfeign.AnnotatedParameterProcessor;
import org.springframework.cloud.openfeign.support.SpringMvcContract;
import org.springframework.core.convert.ConversionService;
import org.springframework.web.bind.annotation.RequestBody;

public class SpringMvcPojoObjectQueryContract extends SpringMvcContract {

public SpringMvcPojoObjectQueryContract(List<AnnotatedParameterProcessor> annotatedParameterProcessors,
    ConversionService conversionService) {
  super(annotatedParameterProcessors, conversionService);
}

@Override
protected boolean processAnnotationsOnParameter(MethodMetadata data, Annotation[] annotations, int paramIndex) {
  boolean httpAnnotation = super.processAnnotationsOnParameter(data, annotations, paramIndex);
  //在springMvc中如果是Get请求且参数中是对象 没有声明为@RequestBody 则默认为Param

    for (Annotation parameterAnnotation : annotations) {
      if (!(parameterAnnotation instanceof RequestBody)) {
        return false;

    data.queryMapIndex(paramIndex);
    return true;
