如何在Glassfish上部署Play Framework 2.4應用程序並閱讀application.conf

Question

我試圖在glassfish上部署play framework 2.4應用程序。 我使用了maven play2插件，並按照以下說明制作了war文件。

https://play2-maven-plugin.github.io/play2-maven-plugin/1.0.0-beta4/war-packaging.html

之后，我嘗試從glassfish控制台部署我的戰爭，但是它返回以下錯誤。

  Error occurred during deployment: Exception while loading the app :

   Please see server.log for more details.

MyBatisModule就是這樣。

public class MyBatisModule extends org.mybatis.guice.MyBatisModule {

    @Override
    protected void initialize() {
        environmentId("development");
        bindConstant().annotatedWith(Names.named("mybatis.configuration.failFast")).to(true);
        bindDataSourceProviderType(PlayDataSourceProvider.class);
        bindTransactionFactoryType(JdbcTransactionFactory.class);
        addMapperClasses();
    }

    @Singleton
    public static class PlayDataSourceProvider implements Provider<DataSource> {
        final Database db;

        @Inject
        public PlayDataSourceProvider(final Database db) {
            this.db = db;
        }

        public DataSource get() {
            return db.getDataSource();
        }
    }

我認為應用程序無法讀取包含數據庫設置的application.conf。 但是我不確定。

你能給我什么建議嗎？

部署應用程序時，我在glassfish控制台上禁用了“隱式CDI”選項。 我現在沒有第一個錯誤，但我又遇到了一個錯誤...

Error occurred during deployment: Exception while loading the app : java.lang.IllegalStateException: 
ContainerBase.addChild: start: org.apache.catalina.LifecycleException: com.google.inject.CreationException:

我的conf / application.conf在這里：

db.default.driver=oracle.jdbc.driver.OracleDriver
db.default.url="jdbc:oracle:thin:@url..."
db.default.username=username
db.default.password=password

它可以在本地環境下工作。 我認為glassfish無法讀取war文件中的application.conf。

對不起。 您能再給我提建議嗎？

Answer 1

一些想法（應該是評論，但是我還不能寫評論）。

1. 如果您的application.conf文件位於WEB-INF/classes目錄中，則應找到該文件（更多信息-https: //www.playframework.com/documentation/2.4.x/ProductionConfiguration#Specifying-an-alternate-configuration-file ）。

2. war文件是否包含JDBC驅動程序？

3. 也許您應該配置JNDI- https://www.playframework.com/documentation/2.4.x/ScalaDatabaseOthers#Exposed-the-datasource-through-JNDI

Answer 2

我的問題原因是：

Caused by: java.sql.SQLException: JDBC4 Connection.isValid() method not supported, connection test query must be configured

https://www.playframework.com/documentation/2.4.x/Migration24#JDBC-connection-pool

在application.conf上添加以下設置后，它可以工作。 （此sql適用於Oracle DB。）

db.default.hikaricp.connectionTestQuery="SELECT 1 FROM DUAL"

謝謝您的幫助！
