休眠错误：调用自定义函数时子树意外结束

【问题标题】：Hibernate ERROR: unexpected end of subtree when calling custom functions休眠错误：调用自定义函数时子树意外结束
【发布时间】：2015-01-08 22:20:36
【问题描述】：

我在我的 PostgreSql 数据库中创建了一个函数，用于根据名为“gen_dairyno()”的财政年度生成一个随机日记号。 我也在hibernate方言中注册了这个功能

registerFunction("gen_dairyno", new StandardSQLFunction("gen_dairyno"));

并且也在 hibernate.cfg.xml 中配置。

我访问该函数的代码如下：

public String generateDiaryNo() {

        return entityManager
                .createQuery(
                        "select gen_dairyno() ").getSingleResult().toString();
    }

问题是当我尝试从应用程序访问它时，它会抛出错误。有人可以帮我解决这个问题吗？

遇到的错误是：

    【解决方案1】：

    经过多次努力，我从Getting Database connection in pure JPA setup找到了解决方案 .我不确定这是否是确切的解决方案。我将代码修改为：

      public String findDiary(String fun, java.sql.Date attributeValue) {
    String diaryNo ="";
    Session session = (Session) entityManager.getDelegate();
    SessionFactoryImplementor sfi = (SessionFactoryImplementor) session.getSessionFactory();
    ConnectionProvider cp = sfi.getConnectionProvider();


    try {
    Connection conn = cp.getConnection();
    CallableStatement cstmt = conn.prepareCall("{? = CALL "+fun+"(?)}");
    cstmt.registerOutParameter(1, Types.VARCHAR);
    cstmt.setDate(2, attributeValue);
    cstmt.executeUpdate();

        diaryNo = cstmt.getString(1);
        System.out.println("Result --> "+diaryNo);
    } catch (SQLException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

    return diaryNo; 
}

    【讨论】：

    • Ehrm.. 一个问题为什么？为什么不简单地使用EntityManager 的createNativeQuery 方法或简单地使用JdbcTemplate？无论哪种方式都会减少您的代码，并且应该也可以工作。
    • 感谢您的宝贵意见。由于我是新手，所以我对 EntityManager 了解不多。我会试试这个并更新代码
