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.
