未报告的异常java.sql.SQLException; 必须被抓住或宣布被扔？

您要么需要在方法中 捕获 异常：

public void setupInfo(){    try    {        // call methods that might throw SQLException    }    catch (SQLException e)    {        // do something appropriate with the exception, *at least*:        e.printStackTrace();    }}

或 声明 抛出方法

SQLException

private void setupInfo() throws SQLException{    // call methods that might throw SQLException}
