Class Logger

java.lang.Object
com.avoka.tm.util.Logger
All Implemented Interfaces:
IBindable
public class Logger extends Object implements IBindable

Provides a Logger class for logging information during the execution of Groovy scripts. A logger instance will be injected into groovy script object before it is invoked. To use the Logger a groovy script class must provide a public Logger field with the name logger.

Service Example

The Groovy class below example below declares a public Logger variable with is used for logging. 

 import com.avoka.tm.util.*
 import com.avoka.tm.vo.*
 import javax.servlet.http.*

 class FluentGroovyService {

     // Injected at runtime
     public Logger logger

     Object invoke(SvcDef svcDef, HttpServletRequest request, User user, Map params) {

         logger.info 'groovy result - ' + params.formId

         return null
     }
 }

Unit Test Example

When using a Logger in a JUnitTest you must specify that the logger field is static otherwise a NPE will occur. This is because the JUnitTest runner will clone the unit test object when executing separate unit test methods to ensure their state is well isolated from other unit test methods. 

 import com.avoka.tm.svc.*
 import com.avoka.tm.test.*
 import com.avoka.tm.util.*
 import com.avoka.tm.vo.*
 import org.junit.*

 class UnitTest extends AbstractJUnitTest {

     // Injected at runtime
     public static Logger logger

     // Perform service unit test
     @Test
     void test() throws Exception {

         Map args = [
             "formId": 23
         ]

         Map params = [
             "svcDef": svcDef,
             "request": null,
             "user": null,
             "params": args
         ]

         def result = new ServiceInvoker(svcDef).invoke(params)

         // Check result
         logger.info params

         assert "groovy result - 23" == result
     }
 }
