Hi Team , 

We are using external database for storing user encrolled courses information purpose . so In 7.0 we are happiely working with external database , Now we are migrating our module service builder from 7.0 to 7.3 . but this much configuration not working with 7.3 and we are getting getService() as null always because of ependency-injector="spring" . so what are the new configurations requires for accessing external database in 7.3 ? 

I am adding my service.xml file below : 

<?xml version="1.0"?>
<!DOCTYPE service-builder PUBLIC "-//Liferay//DTD Service Builder 7.3.0//EN" "http://www.liferay.com/dtd/liferay-service-builder_7_3_0.dtd">

<service-builder dependency-injector="spring" package-path="com.sakai.external.services">
	<namespace>sakai</namespace>
	<entity name="SakaiService" local-service="true" remote-service="false" data-source="liferayDataSource">
	     <column name="sakaiServiceId" type="long" primary="true"></column>
	</entity>
</service-builder>

and the service.xml defined data-source Id , we mentioned inside ext-spring.xml : 

 

<?xml version="1.0"?>

<beans default-destroy-method="destroy" default-init-method="afterPropertiesSet"
   xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">

   <!-- To define an external data source, the liferayDataSource Spring bean 
       must be overridden. Other default Spring beans like liferaySessionFactory 
       and liferayTransactionManager may optionally be overridden. 

       liferayDataSourceFactory refers to the data source configured on the
       application server. -->
   <bean class="com.liferay.portal.dao.jdbc.spring.DataSourceFactoryBean"
       id="liferayDataSourceFactory">
       <property name="propertyPrefix" value="jdbc.sakai.mysql." />
       
   </bean>

   <!-- The data source bean refers to the factory to access the data source.
   -->
   <bean
       class="org.springframework.jdbc.datasource.LazyConnectionDataSourceProxy"
       id="liferayDataSource">
       <property name="targetDataSource" ref="liferayDataSourceFactory" />
   </bean>

   <!-- In service.xml, we associated our entity with the extDataSource. To 
       associate the extDataSource with our overridden liferayDataSource, we define 
       this alias. -->
  
</beans>

and the same prefix , we added inside portal-ext.properties : 

 

jdbc.sakai.mysql.driverClassName=com.mysql.jdbc.Driver
jdbc.sakai.mysql.url=jdbc:mysql://**MySAKAIURL**/sakai12?useUnicode=true&characterEncoding=UTF-8&useFastDateParsing=false
jdbc.sakai.mysql.username=***
jdbc.sakai.mysql.password=***

is anything extra configuration require in 7.3 ?
