Question

我已通过管理控制台配置了GlassFish Server，并添加了JDBC连接池和JDBC资源。从GlassFish ping管理控制台可以获得成功。我正在创建Database对象并从Database类调用插入方法。

Database database = new Database();
BigInteger acSerial = att.getSerialNumber();
BigInteger pkcSerial = att.getHolder().getSerialNumber();
String AC = Base64.getUrlEncoder().encodeToString(att.getEncoded());
database.inserting(acSerial,pkcSerial,AC);

这是我在Database类中的插入方法：

public class Database {
        // JDBC driver name and database URL
        static final String JDBC_DRIVER = "com.mysql.jdbc.Driver";
        static final String DB_URL = "jdbc:mysql://localhost:3306/AC?autoReconnect=true&useSSL=false";

        //  Database credentials
        static final String USER = "XXXXXX";
        static final String PASS = "XXXXXXXX";

        public void inserting(BigInteger acparam, BigInteger pkcparam, String encoded) {
            Connection conn = null;
            Statement stmt = null;
            try{
                //STEP 2: Register JDBC driver
                Class.forName("com.mysql.jdbc.Driver");
                //STEP 3: Open a connection
                conn = DriverManager.getConnection(DB_URL, USER, PASS);
                //STEP 4: Execute a query
                stmt = conn.createStatement();

                String sql = "INSERT INTO ACCredentials " + "VALUES (" +acparam +"," +pkcparam +"," +"'"+encoded+"'" +")" + "";
                stmt.executeUpdate(sql);
            }catch(SQLException se){
                //Handle errors for JDBC
                se.printStackTrace();
            }catch(Exception e){
                //Handle errors for Class.forName
                e.printStackTrace();
            }finally{
                //finally block used to close resources
                try{
                    if(stmt!=null)
                        conn.close();
                }catch(SQLException se){
                }
                try{
                    if(conn!=null)
                        conn.close();
                }catch(SQLException se){
                    se.printStackTrace();
                }
            }
        }
}

我的问题是没有插入MySQL数据库。我尝试过这个没有GlassFish Server的插入示例，但它确实有效。有人知道这个问题吗？

我实际上解决了这个问题。我忘记了DataSource部分：

 public void inserting(BigInteger acparam, BigInteger pkcparam, String encoded) throws NamingException {
        InitialContext ctx;
        DataSource ds;
        Connection conn = null;
        Statement stmt = null;
        ResultSet rs = null;
        try {
            ctx = new InitialContext();
            ds = (DataSource) ctx.lookup("jdbc/MeinDatasourceJndiName");
            //ds = (DataSource) ctx.lookup("jdbc/MySQLDataSource");
            conn = ds.getConnection();
            stmt = conn.createStatement();
            String sql = "INSERT INTO ACCredentials " + "VALUES (" +acparam +"," +pkcparam +"," +"'"+encoded+"'" +")" + "";
            //rs = stmt.executeQuery(sql);
            stmt.executeUpdate(sql);


            while(rs.next()) {
            }
        }
        catch (SQLException se) {

        }

GlassFish Server jdbc无法将记录插入数据库
