使用Glassfish打开与Microsoft SQL的连接时崩溃

问题描述 投票：1回答：2

我正在使用GlassFish 5.0.0开发JavaEE 8应用程序，我想访问驻留在Microsoft SQL Server中的数据库。我在Maven中附加了Microsoft SQL驱动程序7.0 jre8。

当我部署应用程序并尝试打开访问数据库的页面时，我遇到了崩溃。下面的StackTrace。

触发崩溃的代码在这里：

public class DatabaseDatas {
private final static String sqlconn = "jdbc:sqlserver://<redacted>;" +
        "databaseName=dbName";

/**
 * Gets Lelang data in LelangList
 * @return Data in LelangList table
 */
public static ResultSet getLelang(){
    try {
        Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
        Connection sqlconnection = DriverManager.getConnection(sqlconn,"sa","password"); //this is the one which trigger the crash
        sqlconnection.isValid(0); //ignore this
        Statement sta = sqlconnection.createStatement(ResultSet.TYPE_FORWARD_ONLY,ResultSet.CONCUR_READ_ONLY);
        String sql = "SELECT * FROM ListLelang";
        return sta.executeQuery(sql);
    } catch (ClassNotFoundException|SQLException e) {
        e.printStackTrace();
    }
    return null;
}

我使用Jetbrains Intellij IDEA 2018.2.3作为IDE并将JDK 1.8.0_151设置为Project SDK。我还在GlassFish 5 Admin面板的JDBC连接池中设置了javax.sql.DataSource和java.sql.driver。

我不知道为什么会这样。我无法在互联网上的任何地方找到我的错误。请帮我解决这个问题。如果需要，我可以提供更多信息（只要不是个人信息）。谢谢。

编辑：其实我忘了测试连接池。在我尝试通过Glassfish 5管理面板“ping”之后，我得到的错误与上面的堆栈跟踪中的错误相同。 Glassfish admin panel error when pinging to MSSQL connection

使用Java EE，您不应使用DriverManager手动打开与SQL-Server的数据库连接。您的案例中的应用程序服务器（Glassfish）负责打开连接并汇集它们。

正如您所说，您已经为DataSource和JDBC Connection Pool配置了Glassfish，您不需要再次在代码中执行此操作。您现在可以使用DataSource在代码（EJB或CDI）中通过@Resource(lookup="JNDI_NAME_OF_YOUR_DATASOURCE") DataSource dataSource;注入它并使用它。你得到Connection与dataSource.getConnection();。

如果您打算使用EntityManager并使用JPA，则需要在以下目录中的应用程序中使用persistence.xml文件：src/main/resources/META-INF，它可能如下所示：

<persistence xmlns="http://xmlns.jcp.org/xml/ns/persistence"
             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
             xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence
             http://xmlns.jcp.org/xml/ns/persistence/persistence_2_2.xsd"
             version="2.2">
    <persistence-unit name="prod" transaction-type="JTA">
        <jta-data-source>JNDI_NAME_OF_YOUR_CONFIGURED_DATASOURCE</jta-data-source>
        <properties>
            <property name="javax.persistence.schema-generation.database.action" value="drop-and-create"/>
        </properties>
    </persistence-unit>
</persistence>

通过此设置，您现在可以使用EntityManager将@Resource EntityManager entityManager;注入CDI或EJB bean并使用它。

通过这种方法，您可以确保应用程序服务器正在管理与基础架构相关的所有内容（处理数据库），您可以专注于业务逻辑。

我决定彻底抛弃Glassfish（因为据我所知，Glassfish在撰写本文时已经过时了）并使用Apache TomEE（webservice版本）作为web servlet。

即使使用最新的JDK（1.8.0_181），它也能正常工作！再也没有关于MSSQL的错误了。
