Question

我的代码如下所示

@Repository
public interface SaleRepository extends GraphRepository<Sale> {
   @Query("MATCH (n:Sale) WHERE n.userId = {userId} RETURN n")
    Iterable<Sale> getSaleByUserId(@Param("userId") String userId);
}

Sale.JAva

@NodeEntity
public class Sale extends Entity implements Serializable{

   private Date createdDate;

    public Date getCreatedDate() {
        return createdDate;
    }

    public void setCreatedDate(Date createdDate) {
        this.createdDate = createdDate;
    }

}

SaleData.java

@RequestMapping(path = "/connect/{userId}", method = RequestMethod.POST, consumes = "application/json", produces = "application/json")
    public String  SaleData(@PathVariable final String userId) 
    {

                            Sale saleObject = null;
            Iterable<Sale> saleData = SaleRepository.getSaleByUserId(String.valueOf(userPairInfo.getUserId()));
            if(saleData .iterator().hasNext())
            {
                saleObject= saleData .iterator().next();
            }

                         return "{\"userId\":\""+saleObject.getCreatedDate()+"\"}";   // on service call this gives me above error

}

如果我调用该服务我会收到错误，

 java.lang.NoSuchMethodError: com.project.graphdb.neoj.domain.Sale.getCreatedDate()Ljava/util/Date

它主要是因为sale.java文件告诉我还缺少什么？

请帮忙解决这个问题我是java和Neo4j的新手

我认为您使用的是java.util.Date而不是java.sql.Date，或者您可能需要重新编译源代码。

服务调用上的java.lang.NoSuchMethodError
