Question

我是OpenShift的新手，用JBoss AS7和PostgreSQL 9.2齿轮创建了我的第一个应用程序。我成功创建了数据库并尝试按照我在这两个页面上找到的指示部署现有的WAR：

https://www.openshift.com/kb/kb-e1088-how-to-deploy-pre-compiled-java-applications-war-and-ear-files-onto-your-openshift-gear

http://openshift.github.io/documentation/oo_cartridge_guide.html#jbossas

当我做我的git推送时，我得到以下内容：

使用rhc tail我看到以下内容：

任何人都可以帮忙解释为什么我会得到这个以及如何解决它？

非常感谢。

以下是我的standalone.xml中的数据源部分：

        <datasources>
            <datasource jndi-name="java:jboss/datasources/PostgreSQLDS" enabled="${postgresql.enabled}" use-java-context="true" pool-name="PostgreSQLDS" use-ccm="true">
                <connection-url>jdbc:postgresql://${env.OPENSHIFT_POSTGRESQL_DB_HOST}:${env.OPENSHIFT_POSTGRESQL_DB_PORT}/${env.OPENSHIFT_APP_NAME}</connection-url>
                <driver>postgresql</driver>
                <security>
                  <user-name>${env.OPENSHIFT_POSTGRESQL_DB_USERNAME}</user-name>
                  <password>${env.OPENSHIFT_POSTGRESQL_DB_PASSWORD}</password>
                </security>
                <validation>
                    <check-valid-connection-sql>SELECT 1</check-valid-connection-sql>
                    <background-validation>true</background-validation>
                    <background-validation-millis>60000</background-validation-millis>
                    <!--<validate-on-match>true</validate-on-match>-->
                </validation>
                <pool>
                    <flush-strategy>IdleConnections</flush-strategy>
                </pool>
            </datasource>
            <drivers>
                <driver name="postgresql" module="org.postgresql.jdbc">
                    <xa-datasource-class>org.postgresql.xa.PGXADataSource</xa-datasource-class>
                </driver>
            </drivers>
        </datasources>

这是我在WAR中的META-INF目录中的context.xml：

<?xml version='1.0' encoding='utf-8'?>
<Context>
    <Resource name="jdbc/TradeDataSource" auth="Container" type="javax.sql.DataSource"
        username="xxxxx"
        password="xxxxx"
        driverClassName="org.postgresql.Driver"
        url="jdbc:postgresql://127.4.111.132:5432/jbossas"
        maxActive="20"
        maxIdle="10" />
</Context>

Answer 1

每个OpenShift JBoss应用程序都有standalone.xml JBoss配置文件中配置的三个数据源（H2，MySQL和PostgreSQL）。在persistence.xml中，确保使用java:jboss/datasources/PostgreSQLDS JNDI数据源，否则会出现异常。您可以在.openshift / config目录中找到standalone.xml。

Answer 2

我找到的解决方案是在我的WAR中的WEB-INF目录中创建一个专有的jboss-web.xml文件。

在WAR中，WEB-INF / jboss-web.xml包含：

<?xml version="1.0" encoding="UTF-8"?>
<jboss-web>
  <resource-ref>
    <res-ref-name>jdbc/TradeDataSource</res-ref-name>
    <res-type>javax.sql.DataSource</res-type>
    <jndi-name>java:jboss/datasources/PostgreSQLDS</jndi-name>
  </resource-ref>
</jboss-web>

在WAR中，WEB-INF / web.xml包含：

...
<resource-ref id="ResourceRef_1">
  <res-ref-name>jdbc/TradeDataSource</res-ref-name>
  <res-type>javax.sql.DataSource</res-type>
  <res-auth>Container</res-auth>
  <res-sharing-scope>Shareable</res-sharing-scope>
</resource-ref>
...

在.openshift / config目录中，standalone.xml包含

...
<subsystem xmlns="urn:jboss:domain:datasources:1.0">
  <datasources>
    <datasource jndi-name="java:jboss/datasources/PostgreSQLDS" enabled="${postgresql.enabled}" use-java-context="true" pool-name="PostgreSQLDS" use-ccm="true">
      <connection-url>jdbc:postgresql://${env.OPENSHIFT_POSTGRESQL_DB_HOST}:${env.OPENSHIFT_POSTGRESQL_DB_PORT}/${env.OPENSHIFT_APP_NAME}</connection-url>
      <driver>postgresql</driver>
      <security>
        <user-name>${env.OPENSHIFT_POSTGRESQL_DB_USERNAME}</user-name>
        <password>${env.OPENSHIFT_POSTGRESQL_DB_PASSWORD}</password>
      </security>
      <validation>
        <check-valid-connection-sql>SELECT 1</check-valid-connection-sql>
        <background-validation>true</background-validation>
        <background-validation-millis>60000</background-validation-millis>
        <!--<validate-on-match>true</validate-on-match>-->
      </validation>
      <pool>
    <flush-strategy>IdleConnections</flush-strategy>
      </pool>
    </datasource>
    <drivers>
      <driver name="postgresql" module="org.postgresql.jdbc">
        <xa-datasource-class>org.postgresql.xa.PGXADataSource</xa-datasource-class>
      </driver>
    </drivers>
  </datasources>
</subsystem>
...

使用这些文件（以及在standalone.xml和jboss-web.xml中匹配的JNDI名称），WAR成功部署。

使用PostgreSQL在OpenShift JBoss上部署WAR失败 - 缺少依赖性错误
