Spring Integration - Stored Procedure Example - Oracle
|
||||
================================================================================
|
||||
|
||||
# Overview
|
||||
|
||||
This example provides a simple example using the stored procedure outbound gateway
|
||||
adapter. This example will call an Oracle Stored Procedure as well as an Oracle Function using the StoredProc Outbound Gateway.
|
||||
|
||||
This sample was tested against: **Oracle Database Express Edition 11g Release 2** (which can be downloaded and used for free).
|
||||
Nevertheless, the example should work with other versions as well.
|
||||
|
||||
# Setup
|
||||
|
||||
##Pre-requisites
|
||||
|
||||
- Access to a Oracle or Oracle XE database instance
|
||||
- Install Oracle JDBC Driver to your local Maven repository (~/.m2)
|
||||
|
||||
##JDBC Driver installation
|
||||
|
||||
- Go to [http://www.oracle.com/technetwork/indexes/downloads/index.html](http://www.oracle.com/technetwork/indexes/downloads/index.html)
|
||||
- Under "JDBC Drivers", download the appropriate driver relevant to your Oracle and JDK version (This sample was tested using
|
||||
"Oracle Database 11g Release 2 JDBC Drivers")
|
||||
- Once downloaded, install the driver to your local Maven repository:
|
||||
|
||||
$ mvn install:install-file -DgroupId=com.oracle -DartifactId=ojdbc6 -Dversion=11.2.0.3 -Dpackaging=jar -Dfile=~/dev/ojdbc6.jar -DgeneratePom=true
|
||||
|
||||
- Now you can add the dependency to the Maven pom.xml file. Please check the pom.xml for this project and verify that it matches your installed Oracle JDBC driver
|
||||
|
||||
<dependency>
|
||||
<groupId>com.oracle</groupId>
|
||||
<artifactId>ojdbc6</artifactId>
|
||||
<version>11.2.0.3</version>
|
||||
</dependency>
|
||||
|
||||
## Setting Up Oracle
|
||||
|
||||
### Create Tablespace
|
||||
|
||||
CREATE TABLESPACE procedure_test
|
||||
DATAFILE 'c:/data/procedure_test.dbf'
|
||||
SIZE 10M
|
||||
AUTOEXTEND ON NEXT 10M
|
||||
MAXSIZE 100M;
|
||||
|
||||
### Create User
|
||||
|
||||
CREATE USER storedproc
|
||||
IDENTIFIED BY storedproc
|
||||
DEFAULT TABLESPACE procedure_test
|
||||
TEMPORARY TABLESPAC temp;
|
||||
|
||||
### Grant Rights
|
||||
|
||||
GRANT CREATE SESSION,CREATE TABLE,CREATE VIEW,CREATE SEQUENCE TO storedproc;
|
||||
ALTER USER storedproc QUOTA unlimited ON procedure_test;
|
||||
|
||||
### Creating the Stored Procedure
|
||||
|
||||
create or replace
|
||||
PROCEDURE CAPITALIZE_STRING(inoutString IN OUT VARCHAR) IS
|
||||
BEGIN
|
||||
SELECT upper(inoutString) INTO inoutString from dual ;
|
||||
END;
|
||||
|
||||
### Creating the Function
|
||||
|
||||
create or replace
|
||||
FUNCTION GET_COOL_NUMBER
|
||||
RETURN NUMBER
|
||||
IS cool_number NUMBER(11,2);
|
||||
BEGIN
|
||||
cool_number := 12345;
|
||||
RETURN cool_number;
|
||||
END;
|
||||
|
||||
## Setting Up Oracle
|
||||
|
||||
You may have to update the Oracle DB properties in:
|
||||
|
||||
/src/main/resources/META-INF/spring/integration/spring-integration-context.xml
|
||||
|
||||
<bean id="dataSource" class="oracle.jdbc.pool.OracleDataSource" destroy-method="close">
|
||||
<property name="connectionCachingEnabled" value="true" />
|
||||
<property name="URL" value="jdbc:oracle:thin:@//localhost:1521/XE" />
|
||||
<property name="password" value="storedproc" />
|
||||
<property name="user" value="storedproc" />
|
||||
<property name="connectionCacheProperties">
|
||||
<props merge="default">
|
||||
<prop key="MinLimit">3</prop>
|
||||
<prop key="MaxLimit">20</prop>
|
||||
</props>
|
||||
</property>
|
||||
</bean>
|
||||
|
||||
# Run the Sample
|
||||
|
||||
* running the "Main" class from within STS (Right-click on Main class --> Run As --> Java Application)
|
||||
* or from the command line:
|
||||
- mvn package
|
||||
- mvn exec:java
|
||||
