  1. Please add all your Java classes under PLUGIN_HOME/src/main/java/com/krishagni/openspecimen
  2. All the Spring configuration should be done in PLUGIN_HOME/src/main/resources/pluginContext.xml

Lets create a plugin to add a custom print token. Below are the steps to follow:

  1. Create a new project by using the attached skelton
  2. Import this project into any IDE like eclipse

  3. Add new class
    3.1 Add custom token implementation class named SpecimenCollectionProcedurePrintToken.java in package com.krishagni.openspecimen.plugin.token, like below:

    Code Block
    package com.krishagni.openspecimen.plugin.token;

import com.krishagni.catissueplus.core.biospecimen.domain.Specimen;
import com.krishagni.catissueplus.core.common.domain.AbstractLabelTmplToken;
import com.krishagni.catissueplus.core.common.domain.LabelTmplToken;


public class SpecimenCollectionProcedurePrintToken extends AbstractLabelTmplToken implements LabelTmplToken {


	@Override
	public String getName() {
		return "specimen_collection_procedure";
	}

	@Override
	public String getReplacement(Object object) {
		Specimen specimen = (Specimen)object;
		while (specimen.getParentSpecimen() != null) {
			specimen = specimen.getParentSpecimen();
		}

		return specimen.getCollectionEvent().getProcedure();
	}
}


    3.2. Add message key for the newly added label token. To add the message key need to update messages.properties file available at PLUGIN_HOME/src/main/resources/errors. Below is the sample: Register the token into OpenSpecimen with LabelTmplTokenRegistrar. Below is the code:

     

    Code Block
    print_specimen_collection_procedure=Collection Proceudre
 
Note: OpenSpecimen will use this value in the cmd files as the label for collection procedure value.

    3.3. Now we need to register the above token into OpenSpecimen with LabelTmplTokenRegistrar. First create a package com.krishagni.openspecimen.plugin.init and write a class named PluginInitializer. This class will register the above token implementation with OpenSpecimen

     

     

    Code Block
    package com.krishagni.openspecimen.plugin.init;

import org.springframework.beans.factory.InitializingBean;

import com.krishagni.catissueplus.core.common.domain.LabelTmplTokenRegistrar;
import com.krishagni.openspecimen.plugin.token.SpecimenCollectionProcedurePrintToken;


public class PluginInitializer implements InitializingBean {
  
  private LabelTmplTokenRegistrar specimenPrintLabelTokensRegistrar;
   
  public void setSpecimenPrintLabelTokensRegistrar(LabelTmplTokenRegistrar specimenPrintLabelTokensRegistrar) {
      this.specimenPrintLabelTokensRegistrar = specimenPrintLabelTokensRegistrar;
  }

  @Override
  public void afterPropertiesSet() throws Exception {
      specimenPrintLabelTokensRegistrar.register(new SpecimenCollectionProcedurePrintToken());
  }
}
 

    3.4. We have created a custom class for the token and written a plugin initializer which will register the new token with the LabelTmplTokenRegistrar. To make Spring aware to load this class we need to update the spring context. For this we need to add below in file PLUGIN_HOME/src/main/resources/pluginContext.xml

    Code Block
    <bean id="pluginInitializer" class="com.krishagni.openspecimen.plugin.init.PluginInitializer">
  <property name="specimenPrintLabelTokensRegistrar" ref="specimenPrintLabelTokensRegistrar"/>
</bean>
