What's wrong with this? Attempting to add the intermediate bean mentioned in
http://www.jboss.org/index.html?module=bb&op=viewtopic&t=162791. I found that
adding BeanMetaData as a property to a bean seems to cause an unresolved dependency:
| public class ThrowawayTestCase extends MicrocontainerTest
| {
|
| public ThrowawayTestCase(String name)
| {
| super(name);
| }
|
|
| public void testIndirectBean() throws Throwable
| {
| BeanMetaDataBuilder builder =
BeanMetaDataBuilder.createBuilder("Bean", MyBean.class.getName());
| BeanMetaData bmd = builder.getBeanMetaData();
|
| builder = BeanMetaDataBuilder.createBuilder("BeanInstaller",
MyBeanInstaller.class.getName());
| // builder.addPropertyMetaData("context",
builder.createFromContextInject(FromContext.CONTEXT)); //1
| builder.addPropertyMetaData("beanMetaData",
builder.createValue(bmd)); //2
| KernelControllerContext ctx = deploy(builder.getBeanMetaData());
| try
| {
| System.out.println("----------> " +
ctx.getDependencyInfo().getIDependOn(null));
| MyBeanInstaller myBeanInstaller = assertBean("BeanInstaller",
MyBeanInstaller.class);
|
| // MyBean myBean = assertBean("MyBean", MyBean.class);
| // assertNotNull(myBean);
| }
| finally
| {
| undeploy(ctx);
| }
| }
|
| public static class MyBeanInstaller
| {
| KernelControllerContext context;
|
| BeanMetaData beanMetaData;
|
| boolean started;
|
| public BeanMetaData getBeanMetaData()
| {
| return beanMetaData;
| }
|
| public void setBeanMetaData(BeanMetaData beanMetaData)
| {
| this.beanMetaData = beanMetaData;
| }
|
| public KernelControllerContext getContext()
| {
| return context;
| }
|
| public void setContext(KernelControllerContext context)
| {
| this.context = context;
| }
|
| public boolean isStarted()
| {
| return started;
| }
|
| public void start() throws Exception
| {
| //Use context.getController() and beanmetadata to install indirect bean
| }
| }
|
| public static class MyBean
| {
| }
| }
|
The output dependency info is shown as:
| ----------> [AbstractDependencyItem@5f49d886{name=BeanInstaller dependsOn=Bean
whenRequired=Configured dependentState=Installed resolved=false}]
|
Looking at the stack trace of AbstractDependencyItem's constructor it looks like the
property value gets visited as well?

I'm not sure this is something we should fix, without a better understanding of how
the value metadata is visited. I can work around it by creating an intermediate class
| public static class BeanMetaDataWrapper
| {
| private final BeanMetaData beanMetaData;
|
| public BeanMetaDataWrapper(BeanMetaData beanMetaData)
| {
| this.beanMetaData = beanMetaData;
| }
|
| public BeanMetaData getBeanMetaData()
| {
| return beanMetaData;
| }
| }
|
and to set that instead when creating BeanInstaller
| builder.addPropertyMetaData("beanMetaDataWrapper",
builder.createValue(wrapper));
