Class TestContainerClassLoaderFactory

java.lang.Object

org.mule.runtime.container.internal.ContainerClassLoaderFactory

org.mule.test.runner.classloader.TestContainerClassLoaderFactory

All Implemented Interfaces:

AutoCloseable

public class TestContainerClassLoaderFactory
extends ContainerClassLoaderFactory
implements AutoCloseable

Extends the default ContainerClassLoaderFactory for testing in order to add boot packages and build a ClassLoader for the container that do resolves classes instead of delegating to its parent and also allows to create the container ClassLoaderLookupPolicy based on a ClassLoader.

Since:

4.0

Constructor and Description
TestContainerClassLoaderFactory(List<String> extraBootPackages, URL[] urls, ModuleRepository moduleRepository) Factory class that extends the default way to create a container ArtifactClassLoader in order to support the differences when running applications in standalone container vs junit.

Constructor Detail

TestContainerClassLoaderFactory

public TestContainerClassLoaderFactory(List<String> extraBootPackages,
                                       URL[] urls,
                                       ModuleRepository moduleRepository)

Factory class that extends the default way to create a container ArtifactClassLoader in order to support the differences when running applications in standalone container vs junit.

Parameters:

extraBootPackages - List of Strings extra boot packages that need to be appended to the container (junit for instance)

urls - URLs that were classified to be added to the container ClassLoader

moduleRepository - provides access to the modules available on the container. Non null.

Method Detail

createContainerClassLoader

public org.mule.runtime.module.artifact.classloader.ArtifactClassLoader createContainerClassLoader(ClassLoader parentClassLoader)

Overrides method due to it has to use the ClassLoader set to this factory in order to discover modules.

Overrides:

createContainerClassLoader in class ContainerClassLoaderFactory

Parameters:

parentClassLoader - parent classLoader. Can be null.

Returns:

a non null ArtifactClassLoader containing container code that can be used as parent classloader for other mule artifacts.

createArtifactClassLoader

protected org.mule.runtime.module.artifact.classloader.ArtifactClassLoader createArtifactClassLoader(ClassLoader parentClassLoader,
                                                                                                     List<MuleModule> muleModules,
                                                                                                     org.mule.runtime.module.artifact.classloader.ClassLoaderLookupPolicy containerLookupPolicy,
                                                                                                     org.mule.runtime.module.artifact.descriptor.ArtifactDescriptor artifactDescriptor)

Overrides the method in order to create a ArtifactClassLoader that will have a CHILD_FIRST ClassLoaderLookupPolicy, it is needed due to as difference from a mule standalone container where the parent ClassLoader for the container only has bootstrap jars plugins mule modules and third-party libraries when the runner runs this tests using has a full class path with all the artifacts declared as dependencies for the artifact so we have to change that and change the look strategy to be CHILD_FIRST for the container.

The muleModules parameter will be ignored due to it has all the modules in classpath, instead they are discovered once again but using a URLClassLoader that has the URL's classified for the container ClassLoader.

Overrides:

createArtifactClassLoader in class ContainerClassLoaderFactory

Parameters:

parentClassLoader - the parent ClassLoader to delegate PARENT look ups

muleModules - MuleModule discovered from the launcher ClassLoader but will be not considered here due to it has all the class path

containerLookupPolicy - the default ClassLoaderLookupPolicy defined for a container but will be ignored due to it has to be different when running with a full class path as parent ClassLoader

artifactDescriptor -

Returns:

the ArtifactClassLoader to be used for the container

getContainerClassLoader

public org.mule.runtime.module.artifact.classloader.ArtifactClassLoader getContainerClassLoader()

getBootPackages

public Set<String> getBootPackages()

Overrides:

getBootPackages in class ContainerClassLoaderFactory

Returns:

the original list of boot packages defined in ContainerClassLoaderFactory plus extra packages needed to be added in order to allow tests to run with isolation. For instance, junit is an extra package that has to be handled as boot package.

getContainerClassLoaderLookupPolicy

public org.mule.runtime.module.artifact.classloader.ClassLoaderLookupPolicy getContainerClassLoaderLookupPolicy(ClassLoader classLoader)

public void close()
