Restcomm JDBC Resource Adapter Несколько источников данных
Я использую адаптер ресурсов Jdbc 7.1.15 в моем SBB. Это хорошо работает с одним источником данных. Теперь у меня есть требование поговорить со вторым источником данных из моего SBB, но я не смог найти способ сделать это.
Я попытался обновить resource-adapter-jar.xml в ресурсах /jdbc/ra/src/main/resources/META-INF/. добавив другое свойство конфигурации для DATASOURCE_JNDI_NAME.подобно ниже
<resource-adaptor ignore-ra-type-event-type-check="True">

<resource-adaptor-vendor>org.restcomm</resource-adaptor-vendor>

<resource-adaptor-type-vendor>org.restcomm</resource-adaptor-type-vendor>
<resource-adaptor-type-version>1.0</resource-adaptor-type-version>
</resource-adaptor-type-ref>

<config-property-type>java.lang.Boolean</config-property-type>
<config-property-value>true</config-property-value>
</config-property>
</resource-adaptor>
но как только я разверну его, я получу ошибки развертывания. У меня вопрос, есть ли способ настроить jdbc RA для использования двух или более источников данных одновременно?

Чтобы иметь несколько источников данных для адаптера ресурсов Restcomm SLEE Jdbc, необходимо сначала изменить файлы resource-adapter-jar.xml и deploy-config.xml в restcomm-slee-ra-jdbc и restcomm-slee-ra- проекты jdbc-DU соответственно. Вот пример файла resource-adapter-jar.xml, в котором определены два JdbcResourceAdaptors. Один для каждого источника данных.
<?xml version="1.0" encoding="ISO-8859-1"?>

Затем файл deploy-config.xml необходимо обновить с именами сущностей. В моем случае я создал имена сущностей JDBCRA и JDBCRA-Config. JDBCRA будет источником данных для статистики приложения, а JDBCRA-Config будет источником данных для конфигурации приложения.
<?xml version="1.0" encoding="UTF-8"?>
<deploy-config>
<ra-entity
resource-adaptor-id="ResourceAdaptorID[name=JdbcResourceAdaptor,vendor=org.restcomm,version=1.0]"
entity-name="JDBCRA">
<properties/>
<ra-link name="JDBCRA" />
</ra-entity>
<ra-entity
resource-adaptor-id="ResourceAdaptorID[name=JdbcResourceAdaptor,vendor=org.restcomm,version=1.0]"
entity-name="JDBCRA-CONFIG">
<properties/>
<ra-link name="JDBCRA-CONFIG" />
</ra-entity>
</deploy-config>
Затем обновите standalone.xml для сервера приложений WildFly (restcomm-slee-7.1.83.87-wildfly-10.1.0.Final), чтобы включить два источника данных:
<subsystem xmlns="urn:jboss:domain:datasources:4.0">
...
<datasource jndi-name="java:/STATS_DS" pool-name="STATS_DS">
<connection-url>jdbc:postgresql://localhost:5432/appstats</connection-url>
<driver>postgres</driver>
<pool>
<min-pool-size>20</min-pool-size>
<initial-pool-size>50</initial-pool-size>
<max-pool-size>150</max-pool-size>
</pool>
<security>
<user-name>user</user-name>
<password>password</password>
</security>
</datasource>
<datasource jndi-name="java:/AppConfigDS" pool-name="AppConfigDS">
<connection-url>jdbc:postgresql://localhost:5432/appconfig</connection-url>
<driver-class>org.postgresql.Driver</driver-class>
<driver>postgres</driver>
<security>
<user-name>username</user-name>
<password>password</password>
</security>
</datasource>
...
</datasources>
</subsystem>
Во-вторых, в вашем приложении JAIN-SLEE определите два SBB, а именно StatsDataSourceSBB и ConfigDataSourceSBB. В файле sbb-jar.xml приложения JAIN-SLEE настройте каждый SBB следующим образом:
<?xml version="1.0" encoding="utf-8"?>

Это должно позволить вам определить несколько источников данных для вашего Restcomm JAIN-SLEE JDBC RA.
Надеюсь это поможет.
