Question

我尝试在glassfish上部署play framework 2.4应用程序。我使用maven play2插件并使用以下指令制作war文件。

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

之后，我尝试从glassfish控制台部署我的战争，但它返回了以下错误。

  Error occurred during deployment: Exception while loading the app :

   Please see server.log for more details.

MyBatisModule就像这样。

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();
        }
    }

我认为应用程序无法读取包含数据库设置的application.conf。但我不确定。

你能给我任何建议吗？

我禁用了＃34;隐含的CDI＆＃34;我部署应用程序时在glassfish控制台上的选项。我现在没有收到第一个错误，但是我收到了另一个错误......

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在这里：

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

它适用于当地环境。我认为glassfish无法在war文件中读取application.conf。

对不起。你能再次给我一些建议吗？

Answer 1

一些想法（应该是评论，但我还不能在SO上发表评论）。

如果您的application.conf文件位于WEB-INF/classes目录中，则应找到该文件（更多信息 - https://www.playframework.com/documentation/2.4.x/ProductionConfiguration#Specifying-an-alternate-configuration-file）。
war文件是否包含JDBC驱动程序？
也许您应该配置JNDI - https://www.playframework.com/documentation/2.4.x/ScalaDatabaseOthers#Exposing-the-datasource-through-JNDI

Answer 2

我的问题原因是：

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上添加以下设置后，它可以正常工作。（此sql适用于Oracle DB。）

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

感谢您的帮助！
