Hibernate 弹簧靴&x2B；冬眠+；JPA=使用存储库的命名oracle过程调用失败

我想知道为什么：

使用repo失败，而使用EntityManager工作正常

“org.hibernate.procedure.ParameterStrategyException:尝试访问位置参数[1]，但在将唯一的参数命名后抛出“使用命名参数调用ProcedureCall”（将“name=“po_list”添加到@StoredProcedureParameter，将“outputParameterName=“po_list”添加到@procedure）

在没有结果的情况下尝试：

替换“resultClasses=ReferenceInsurance.class”

将“type=void.class”替换为“type=class.class”，并替换为“type=ReferenceInsurance.class”

应用程序：

package org.nyulmc.db;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Bean;
import org.springframework.data.jpa.repository.config.EnableJpaRepositories;

import javax.persistence.EntityManager;
import java.util.List;

@SpringBootApplication(scanBasePackages = "org.nyulmc.db")
@EnableJpaRepositories(basePackages = "org.nyulmc.db")
@EnableAutoConfiguration
public class DbPackageOnly {

    @Bean
    public Object usingEntityManager(EntityManager em) {
        final List<ReferenceInsurance> list = em.createNamedStoredProcedureQuery("getRefEpicWebListNew").getResultList();
        return list;
    }

    @Bean
    public Object usingRepo(Repo repo) {
        final List<ReferenceInsurance> refEpicWebListNew = repo.getRefEpicWebListNew();
        return refEpicWebListNew;
    }

    public static void main(String[] args) {
        SpringApplication springApplication = new SpringApplication(DbPackageOnly.class);
        springApplication.setAdditionalProfiles("ora_dev");
        springApplication.run(args);
    }

}

Oracle过程签名：

PROCEDURE get_RefEpicWebListNew(po_list OUT mycursor)

回购：

    id "io.spring.dependency-management" version "1.0.9.RELEASE"
    id 'org.springframework.boot' version '2.0.9.RELEASE'
    ...
}
dependencies {
