I want to create a restService with Springboot. But I want a configurable datasource, I want to have the capacity to add a new datasource when I want. But I have this exception :
> No qualifying bean of type 'javax.sql.DataSource' available: expected
> single matching bean but found 2
And I'm using this code :
<bean id="jpaVendorAdapter" class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
<property name="showSql" value="true"/>
<property name="generateDdl" value="true"/>
<property name="database" value="ORACLE"/>
</bean>
<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="oracle.jdbc.OracleDriver"/>
<property name="url" value="jdbc:oracle:thin:#localhost:9999:TEST"/>
<property name="username" value="test"/>
<property name="password" value="test"/>
</bean>
<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="dataSource" ref="dataSource"/>
<property name="jpaVendorAdapter" ref="jpaVendorAdapter"/>
<!-- spring based scanning for entity classes-->
<property name="packagesToScan" value="com.orange.aurore.model.entity"/>
<property name="persistenceUnitName" value="msPersistenceUnit" />
</bean>
<bean id="controllerService" class="...controller.impl.ControllerServiceImpl">
<property name="entityManager" ref="entityManagerFactory" />
<property name="dataSource" ref="dataSource"/>
</bean>
and :
<bean id="dataSource2" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="oracle.jdbc.OracleDriver"/>
<property name="url" value="jdbc:oracle:thin:#localhost:9999:TEST"/>
<property name="username" value="test2"/>
<property name="password" value="test2"/>
</bean>
<bean id="entityManagerFactory2" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="dataSource" ref="dataSource2"/>
<property name="jpaVendorAdapter" ref="jpaVendorAdapter"/>
<!-- spring based scanning for entity classes-->
<property name="packagesToScan" value="com.orange.aurore.model.entity"/>
<property name="persistenceUnitName" value="msPersistenceUnit2" />
</bean>
<bean id="controllerService2" class="...controller.impl.ControllerServiceImpl">
<property name="entityManager" ref="entityManagerFactory2" />
<property name="dataSource" ref="dataSource2"/>
</bean>
and in java code :
public void setEntityManager(final HibernateEntityManagerFactory entityManager) {
final RepositoryFactorySupport factorySupport = new JpaRepositoryFactory(entityManager.createEntityManager());
controlRepository = factorySupport.getRepository(ObjControlRepository.class);
Thanks you for your help.
It was a stupide mistake I juste add primary="true" for one of my two configuration.

I'm setting up two different datasource for diff databse in spring-servlet.xml
I have tried multiple solutions provided on sites most of them are for spring-boot.
<bean id="dataSource"
class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="oracle.jdbc.driver.OracleDriver" />
<property name="url" value="jdbc:oracle:thin:#localhost:1521:xe" />
<property name="username" value="***" />
<property name="password" value="***" />
</bean>
<bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate">
<property name="dataSource" ref="dataSource" />
</bean>
<bean id="dataSourceDev"
class="org.springframework.jdbc.datasource.DriverManagerDataSource">

<property name="password" value="***" />
</bean>
<bean id="jdbcTemplateDev" class="org.springframework.jdbc.core.JdbcTemplate">

</bean>
In java class -

I have configured a 2 dataSources in my SpringMVC Project, but when the 2nd
dataSource is unavailable it automatically uses 1st datasource where 2nd is referred.
I want to stop this switching.
Here is the code:
dispatcher-servlet.xml:
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource" />
</bean>
<bean id="dataSource" destroy-method="close" class="org.apache.commons.dbcp.BasicDataSource" lazy-init="false">
<property name="driverClassName" value="${jdbc.driverClassName}"/>
<property name="url" value="${jdbc.url}"/>
<property name="username" value="${jdbc.username}"/>
<property name="password" value="${jdbc.password}"/>
<property name="defaultAutoCommit" value="true"/>
<property name="testOnBorrow" value="true"/>
<property name="initialSize" value="1"/>
<property name="maxActive" value="1"/>
<property name="maxWait" value="500"/>
<property name="maxIdle" value="2"/>
</bean>
<bean id="dataSource1" destroy-method="close" class="org.apache.commons.dbcp.BasicDataSource" lazy-init="false">
<property name="driverClassName" value="${jdbc.driverClassName1}"/>
<property name="url" value="${jdbc.url1}"/>
<property name="username" value="${jdbc.username1}"/>
<property name="password" value="${jdbc.password1}"/>
<property name="defaultAutoCommit" value="true"/>
<property name="testOnBorrow" value="true"/>
<property name="initialSize" value="1"/>
<property name="maxActive" value="3"/>
<property name="maxWait" value="500"/>
<property name="maxIdle" value="8"/>
</bean>
BaseNamedParameterJdbcDaoSupport.java class:
public class BaseNamedParameterJdbcDaoSupport extends NamedParameterJdbcDaoSupport{
#Autowired
public void setDataSourceFor1(DataSource dataSource) {
// System.out.println("Main DS"+dataSource);
setDataSource(dataSource);
}
}
BaseNamedParameterJdbcDaoSupportForMirrorDB.java :
public class BaseNamedParameterJdbcDaoSupportForMirrorDB extends NamedParameterJdbcDaoSupport{
#Autowired
public void setDataSourceFor2(DataSource dataSource1) {
// System.out.println("ForMirrorDB dataSource1"+dataSource1);
setDataSource(dataSource1);
}
}
It is not possible that the DataSource which are maintained with different name will automatically switch. I think you have implemented some other logic to work with these two DataSource objects.
Check your DAO/Service code to utilizing the "BaseNamedParameterJdbcDaoSupport" & "BaseNamedParameterJdbcDaoSupportForMirrorDB" with proper #Autowired.

Connections and configurations are created properly, the bug I have made was in bean.xml i have used myBatis bean id, and camel route i have type as mybatis, due to case-sensitive, no environment was created, sorry for that.
I want to use mysql database in spring batch application. Where should I keep my XML file with the details of datasource.
currently i have kept the env-context.xml in src/main/resources/META-INF/batch/override/manager
Content of env-context.xml:
<!-- connect to database -->
<bean id="dataSource"
class="org.apache.commons.dbcp.BasicDataSource">
<property name="driverClassName" value="com.mysql.jdbc.Driver" />
<property name="url" value="jdbc:mysql://localhost:3306/demo_db" />
<property name="username" value="testuser" />
<property name="password" value="12345" />
</bean>
<bean id="transactionManager"
class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource" />
</bean>
The common approach is to put this kind of configuration parameters into a properties file in order to externalize them as they will change from one environment to another.
It can be done as next:
<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="locations">
<value>classpath:datasource.properties</value>
</property>
</bean>
<bean id="dataSource"
class="org.apache.commons.dbcp.BasicDataSource">
<property name="driverClassName" value="${datasource.driver}" />
<property name="url" value="${datasource.url}" />
<property name="username" value="${datasource.username}" />
<property name="password" value="${datasource.password}" />
</bean>
<bean id="transactionManager"
class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource" />
</bean>
Then you put your file datasource.properties into the classpath, this file will have a content of type:
datasource.driver=com.mysql.jdbc.Driver
datasource.url=jdbc:mysql://localhost:3306/demo_db
datasource.username=testuser
datasource.password=12345
I've a problem with the Flyway schema upgrader for Spring. Following code exists in my servlet.xml
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
<property name="driverClassName" value="com.mysql.jdbc.Driver"/>
<property name="url" value="jdbc:mysql://localhost/database"/>
<property name="username" value="root"/>
<property name="password" value="password"/>
</bean>
<bean id="flyway" class="com.googlecode.flyway.core.Flyway" init-method="migrate" depends-on="dataSource">
<property name="dataSource" ref="dataSource"/>
</bean>
But how to set the migration script directory or rather whats the default directory?
Everything is explained in the excellent documentation:
If you want to alter the default directory (which is db/migration as shown on the picture above), I believe this should work (see: Flyway.setBaseDir()):
<bean id="flyway" class="com.googlecode.flyway.core.Flyway" init-method="migrate" depends-on="dataSource">
<property name="dataSource" ref="dataSource"/>
<property name="baseDir" value="my/migrations/path"/>
</bean>
