I need to check how works spring web application.
I think to set breakpoints in constructors of all beans.
In this way I suppose can receive perception which bean created, order of creation, links between beans. Is this way correct?
Thanks
You can download STS which is a fork of Eclipse produced by SpringSource. I think you can also just add an STS plugin to a regular Eclipse install. It has a "spring explorer" view that lets you browse the bean config, even if they are wired via annotations.

I'be been struggling for about 20 hours and also working in the weekend as you can see and I can't make this work. I think I have exhausted all the online options
I have copied the example here
https://rieckpil.de/howto-simple-form-based-authentication-for-jsf-2-3-with-java-ee-8-security-api/
in a new Dynamic web project in Eclipse for Java Enterprise Developers. I activated JSF 2.3 in the project facets (since I know that TomEE can use them)
I copied the classes, I set the web.xml to be the same.
My project runtime is TomEE8 (which is basically Tomcat9 with CDI and other stuff)
When I try to run the project on TomEE, I get this error:
javax.enterprise.inject.UnsatisfiedResolutionException: Api type
[javax.security.enterprise.SecurityContext] is not found with the
qualifiers Qualifiers: [#javax.enterprise.inject.Default()] for
injection into Field Injection Point, field name : securityContext,
Bean Owner : [LoginBacking, WebBeansType:MANAGED, Name:loginBacking,
API Types:[java.lang.Object,LoginBacking],
Qualifiers:[javax.inject.Named,javax.enterprise.inject.Default,javax.enterprise.inject.Any]]
I have tried creating the beans.xml file in my WEB-INF folder
I have created another bean with this annotation:
#FacesConfig(
// Activates CDI build-in beans
version = JSF_2_3
)
I have tried not using TomEE and using Tomcat 9 with weld, same problem.
I have no idea how to make this work. The thing is I need to add user login to my main application, but if this simple example won't work I don't think I can do this and I'm feeling very down.
If anyone can help me see the light, I'd be appreciative. I am also open to using the old method (ManagedBean and ManagedProperty I guess), but I'm not sure if it has the same effect.
Thanks!
Time for an answer.
It seems like TomEE does not provide an implementation for javaee-web-api. I had to add my own.
I have added the Soteria implementation to my lib file
https://search.maven.org/classic/#search%7Cga%7C1%7Ca%3A%22javax.security.enterprise%22
Now all seems well (at least the app is running).
Good luck!
I am going to create Java Application that can load external jar files at runtime by FileChooser. I am using Spring Framework, and I want to load jar file and its applicationContext.xml file and inject its dependencies dynamically. I tried to achieve this by OSGi, but it seems very complicated so that I am searching another appropriate variants.
I want to make something like Intellij IDEA plugin installation from the disk.
How can I do this? (After the jar file chosen restarting an application also accepted)
I realy like your approach, unfortunately spring has lifecycles that are strict. As you might know, spring autowires "beans" only. Exactly one lifecycle registers the different bean candidates. After that lifecycle spring (by default) does not accept new classes.
You must use the spring-osgi.
If you only need the CDI part out of spring, you might like to use a different CDI like red hat's jboss server.
I have created a simple web app by following the book "Mastering Spring MVC". Everything was working fine, however, during the testing chapter, I have created two beans with #Primary annotation. 1. ProviderSignInController and 2. An Impl of my search service class. Both of these are in package src/test/java.
The problem here is that if I deploy my application, even then, these two beans come into the picture and I am not able to work with my actual authentication and search service.
I am not getting any error or exception. I would like to know what could be the best way to automatically inject my mocks/stubs while testing and actual implementations when I deploy the app in my dev environment.
The source code link is here. Thanks.
Instead of #Primary, I'd suggest using #Profile("PRODUCTION") along side #Bean for your real/production beans/classes & #Profile("!PRODUCTION") with your test beans/classes. Then, specify the active profile(s) at runtime
-Dspring.profiles.active=PRODUCTION, ...
The problem was the way I was executing the application.
When I launched the application directly from eclipse (Run As Spring Boot App), the tests were included in the build as they were present in the classpath.
I modified my approach and now I am using gradle build (gradle bootRun) to launch my app. This solves the problem. Thanks to #DwB for providing the hint.
Actually we are using the Spring for the dependency injection for the decorator design pattern.So the beans will be spread across the different XML files. i Need Some tool or plugin in the Eclipse that navigate rule-ref to the Actual bean location. So analyzing will be easy.
Since you are developing a spring based application I would suggest you to use Spring Tools Suite. I have been using it and makes it easier to navigate across the XML files. Just cntrl+click on the ref does the magic.
Make sure the the bean configuration files when viewed in eclipse have this icon.
I have couple of beans defined in the applicationContext.xml file and found if I made mistake(say typo) with the bean's name, spring won't complain anything and go ahead load the invalidate configuration. doesn't spring do the checking automatically? and how can i implement schema validation on the applicationContext.xml file? thanks.
IntelliJ IDEA has a wonderful support for Spring, including:
detecting broken references (bean does not exist, has a wrong type, etc.)
completing bean names when Ctrl+Space is pressed (along with narrowing the list to only the beans matching by type)
discovering missing/duplicated beans when #Resource/#Autowired is used and it will fail to autowire at runtime
quick navigation between Java and application context XML
...and lots more
Also I strongly recommend writing Spring smoke integration test. It doesn't have to test anything, just context startup (you would be amazed, how many errors it discovers).
To avoid errors in spring context I suggest you to use a plugin which checks its contents, for instance springIDE or SpringSource Tool Suite. In this way the plugin validates your spring contexts during development and you can find errors before the execution of your application.
in addition to this problem , i had problems with detecting duplicate bean ids that would get overridden unintentionally among others but finally i found this open-source project that helps you write JUnit unit tests that going to detect these problems. it was very easy to use and solved my problemsm it's called Beanoh
