Question

Can anyone provide complete example of Stored Procedure call with Spring framework.
Thanks,

Answer 1

Using the Spring stored procedure framework:
jdbc-config.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:util="http://www.springframework.org/schema/util"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-3.0.xsd">
<bean id="dataSource" class="org.springframework.jndi.JndiObjectFactoryBean">
<property name="jndiName" value="java:comp/env/orcl/DB"/>
</bean>
<bean id="storedProc" class="com.DatabaseStoredProc">
<property name="dataSource" ref="dataSource" />
<property name="sql" value="aStoredProc" />
<property name="parameters">
<list>
<bean class="org.springframework.jdbc.core.SqlParameter">
<constructor-arg index="0" value="p_id1" />
<constructor-arg index="1">
<util:constant static-field="java.sql.Types.VARCHAR" />
</constructor-arg>
</bean>
<bean class="org.springframework.jdbc.core.SqlParameter">
<constructor-arg index="0" value="p_id2" />
<constructor-arg index="1">
<util:constant static-field="java.sql.Types.VARCHAR" />
</constructor-arg>
</bean>
</list>
</property>
</bean>
</beans>
DatabaseStoredProcedure class
import java.util.Map;
import org.springframework.jdbc.object.StoredProcedure;
public class DatabaseStoredProc extends StoredProcedure {
public Map<String, Object> execute(Map inputs){
Map out=super.execute(inputs);
return null;
}
// Method to map data to inputs Map:
public boolean businessRules(Object obj, Map inputs){
SomeObject otd = (SomeObject) obj;
inputs.put("p_id1", otd.getId1());
inputs.put("p_id2", otd.getId2() );
return true;
}
}

Answer 2

Create a Controller with reference to which you inject your datasource (applicationContext.xml):
<bean id="storedProcedureDao" class="com..myapp.SpringStoredProcedureDao">
<property name="dataSource">
<ref bean="jtdsDataSource"/>
</property>
</bean>
Data source:
<bean id="jtdsDataSource" class="net.sourceforge.jtds.jdbcx.JtdsDataSource">
<property name="serverName">
<value>servername</value>
</property>
<property name="databaseName">
<value>database</value>
</property>
<property name="user">
<value>username</value>
</property>
<property name="password">
<value>password</value>
</property>
</bean>
In your Controller, put the following:
public class SpringStoredProcedureDao extends StoredProcedure {
private DataSource dataSource;
public void setDataSource(DataSource dataSource) {
this.dataSource = dataSource;
}
public CallStoredProcedure(String procedureName){
super(this.dataSource, procedureName);
compile();
}
}
This should more or less be it :)

The above solution won't work, as you cannot call a super class constructor in a sub class method. It has to be called within the sub class constructor
