如何在spring boot中使用hibernate entitymanager调用带输出参数的MySQL存储过程

import javax.persistence.EntityManager;
import javax.persistence.EntityManagerFactory;
import javax.persistence.ParameterMode;
import javax.persistence.StoredProcedureQuery;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

@Service
public class MyService {

    @Autowired
    private EntityManagerFactory entityManagerFactory;

    public void callStoredProcedure() {
        EntityManager entityManager = entityManagerFactory.createEntityManager();

        StoredProcedureQuery query = entityManager.createStoredProcedureQuery("your_stored_procedure_name");
        query.registerStoredProcedureParameter("input_param", String.class, ParameterMode.IN);
        query.registerStoredProcedureParameter("output_param", String.class, ParameterMode.OUT);

        query.setParameter("input_param", "input_value");

        query.execute();

        String outputValue = (String) query.getOutputParameterValue("output_param");
        System.out.println("Output parameter value: " + outputValue);

        entityManager.close();
    }
}
