晚上好，
我有一个关于EJB定时器的问题，我不知道我能做些什么来解决它。
在我的项目中有一些方法，除了"CargaC"之外，所有的方法都工作得很好。当我调用它时，我得到一个msg错误：
我的代码：

public void CargaC() {
        Connection db2 = null;
        DadosCDao dadosCDao = new DadosCDao();
        try{
            if(db2 == null || db2.isClosed()){
                if((db2==null)||(db2.isClosed())){
                    db2 = new Dao().conexaoDb23();
                    if(!db2.isValid(5)){
                        db2 = new Dao().conexaoDb2K();
                        if(!db2.isValid(5)){
                            db2 = new Dao().conexaoDb2R();
                        }
                    }
                }
                ArrayList<DadosC> lista = dadosCDao.cargaDadosDb2(db2);
                if(!lista.isEmpty()){
                    verificaDados(lista);
                }

            }
            db2.close();
        }catch(SQLException e){
            System.out.println("Projeto PrjX, classe CargaDadosC, método cargaC, erro: "+e.getMessage());
        }
    }

错误消息：

isValid方法是在JDBC 4.0中添加的。您似乎正在使用db2jcc.jar（JDBC 3.0）而不是db2jcc4.jar（JDBC 4.0）。

对我来说，排除HikariCP工作。

我知道这是很久以前的事了，但原因是使用了不支持查询验证功能的jcc jar。
我有以下设置在我的application.properties（Spring Boot ）：

db2.datasource.validationQuery=SELECT 1
db2.jpa.hibernate.dialect=org.hibernate.dialect.DB2390Dialect

如果我使用旧版本的jcc jar，这将导致所描述的错误。
在我的例子中，我可以很容易地重现这个问题：

  • 使用db2jcc jar（在我的例子中是版本10.1）将导致此错误
  • 使用db2jcc4.jar，错误不会发生，isValid（）执行正常
