Apache Camle & Dozer - Java Bean to Bean mapper using Dozer. (11/250-2016)

Using dozer for Java Bean to Bean mapping in Apache Camel - makes life extremely simple to recursively copy data from one object to another.
The below steps will help to quickly add a dozer mapping file in OSGI Blueprint xml

• In the blueprint.xml add the bean definitions below
  Note - the name of the camel context should be same as the argument index="0"

<bean id="dozerConverterLoader"
  class="org.apache.camel.converter.dozer.DozerTypeConverterLoader">
  <argument index="0" ref="abcdCamelContext" />
  <argument index="1" ref="abcMapper" />
</bean>
<bean id="abcMapper" class="org.apache.camel.converter.dozer.DozerBeanMapperConfiguration" />

• Inside the route include the sample code to invoke the dozer mapping file.
• Also mention the expected source object / destination object
• 
  

<camelContext id="abcdCamelContext" xmlns="http://camel.apache.org/schema/blueprint">
  <route>
    <from uri="direct:test" />

    .....
<to uri="dozer:submitRequest?mappingFile=mapping/abcd.xml&amp;sourceModel=com.abcd.SourceReq&amp;targetModel=com.abcd.DestReq" />

    .....

  </route>

</camelContext>

• Mapping file - location - under src/main/resources

• Mapping file - sample
• Please follow the dozer documentation for complex beans.

<mappings xmlns="http://dozer.sourceforge.net" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://dozer.sourceforge.net  http://dozer.sourceforge.net/schema/beanmapping.xsd">
  
  <mapping wildcard="false">
    <class-a>com.abcd.SourceReq</class-a>
    <class-b>com.abcd.DestReq</class-b>
    
    <field>
      <a>caseNumberSrc</a>
      <b>caseNumberDest</b>
    </field>

  </mapping>

</mappings>

• Sample Source Object - SourceReq

public class SourceReq {
 
 String caseNumberSrc;
 
 public String getCaseNumberSrc() {
  return caseNumberSrc;
 }
 public void setCaseNumberSrc(String caseNumberSrc) {
  this.caseNumberSrc = caseNumberSrc;
 }

}

• Sample Destination Object - DestReq

public class DestReq {

 String caseNumberDest;

 public String getCaseNumberDest() {
  return caseNumberDest;
 }

 public void setCaseNumberDest(String caseNumberDest) {
  this.caseNumberDest = caseNumberDest;
 }
}
