The ibatis: component allows you to query, poll, insert, update and delete data in a relational database using Apache iBATIS.

URI format

Code Block

ibatis:statementName[?options]

Where statementName is the name in the iBATIS XML configuration file which maps to the query, insert, update or delete operation you wish to evaluate.

...

Maven users will need to add the following dependency to their pom.xml for this component:

Code Block

<dependency>
    <groupId>org.apache.camel</groupId>
    <artifactId>camel-ibatis</artifactId>
    <version>x.x.x</version>
    <!-- use the same version as your Camel core version -->
</dependency>

h3. URI format

ibatis:statementName?options

Code Block


Where *statementName* is the name in the iBATIS XML configuration file which maps to the query, insert, update or delete operation you wish to evaluate.

You can append query options to the URI in the following format, {{?option=value&option=value&...

...

}}

This component will by default load the iBatis SqlMapConfig file from the root of the classpath and expected named as {{SqlMapConfig.xml}}.

...


It uses Spring resource loading so you can define it using {{classpath}}, {{file}} or {{http}} as prefix to load resources with those schemes.

...


In Camel 2.2 you can configure this on the iBatisComponent with the {{setSqlMapConfig(String)}} method.

Message Body

h3. Message Body
*Camel 1.6.1*: The response from iBatis will be set as OUT body

...

 
*Camel 1.6.2/2.0*: The response from iBatis will only be set as body if it's a {{SELECT}} statement. That means, for example, for {{INSERT}} statements Camel will not replace the body. This allows you to continue routing and keep the original body. The response from iBatis is always stored in the header with the key {{CamelIBatisResult

}}.

h3. Samples

For example if you wish to consume beans from a JMS queue and insert them into a database you could do the following:

Samples

For example if you wish to consume beans from a JMS queue and insert them into a database you could do the following:

...

from("activemq:queue:newAccount").

...


to("ibatis:insertAccount?statementType=Insert");

Code Block

Notice we have to specify the {{statementType}}, as we need to instruct Camel which {{SqlMapClient}} operation to invoke.

...



Where *insertAccount* is the iBatis ID in the SQL map file:

...


{code
:xml
xml
}
  <!-- Insert example, using the Account parameter class -->
  <insert id="insertAccount" parameterClass="Account">
    insert into ACCOUNT (
      ACC_ID,
      ACC_FIRST_NAME,
      ACC_LAST_NAME,
      ACC_EMAIL
    )
    values (
      #id#, #firstName#, #lastName#, #emailAddress#
    )
  </insert>
