当我尝试使用 dataSource.getConnection() 建立连接时

不允许请帮忙

*****连接代码**********

公共类 DatabaseBeanH2 {

private DataSource dataSource;
private static final Logger LOGGER = LoggerFactory.getLogger(DatabaseBeanH2.class);

public DatabaseBeanH2(){}

public void setDataSource(DataSource dataSource) {
    this.dataSource = dataSource;
}

public void create() throws SQLException{
    Statement sta = dataSource.getConnection().createStatement();
    try {
        sta.executeUpdate("CREATE TABLE orders ( id INT NOT NULL PRIMARY KEY AUTO_INCREMENT, item VARCHAR(50), amount INT, description VARCHAR(300), processed BOOLEAN, consumed BOOLEAN);");
    } catch (SQLException e) {
        LOGGER.info("Table orders already exists");
    }
}

public void destroy() throws SQLException {
    dataSource.getConnection().close();
}

}

您必须在骆驼/弹簧上下文中的 DatabaseBeanH2 中注入 dataSource bean，如下所示：

<bean id="databaseBean" class="my.package.DatabaseBeanH2">
    <property name="dataSource" ref="dataSource" />
</bean>
