Why can't Maven build resolve Spring #Bean #Configuration etc annotations?

Why can't Maven build resolve Spring #Bean #Configuration etc annotations? - java

I'm trying to move my Spring MVC project to 3.2.4.
When I attempt to run up the application in IntelliJ, using Maven as I had done previously, I am getting errors about not being able to find a series of annotation classes from Spring...
#Bean
#Configuration
#ComponentScan
#PropertySource
are all failing with unable to resolve class error messages.
Other annotations are ok, which makes me think it is a dependency issue, as the Spring version is the main change in my project codebase.
Has Spring 3.2.4 changed where those annotations live in the packaging?
My current pom (some bits removed for brevity):

There is a duplicate dependency of org.springframework:spring-context in your POM that is probably causing classpath conflicts. The first one is a compile dependency using version 3.2.4.RELEASE, and the second one is a runtime dependency using version 3.0.0.RELEASE.
I suggest you remove the second since it's unnecessary and should be superseded by the first.

Spring is not verbose about what is going wrong. To debug this, copy annotated class into the .war project and make it work there. A lot of thing may be wired wrong but spring will only say unsatisfied auto-wiring.
It should work out-of-the-box, so something is not done properly. A property not set, a dependency not met etc.
When you copy it in your project you simplify the problem, once it work there, move back the class and it should work fine!

Deploy on Tomcat from eclipse in ROOT folder

Hi' I'd like to make my application deploy in ROOT folder (I hope to fix my problem about twice deploy).
I'm using maven and Tomcat v8 but even if I change pom.xml like below the result doesn't change.
I have tried to manually ad ROOT.war but when I start Tomcat from Eclipse it make deploy under application name folder. The path into the web modules is /ROOT
Do you know how can I deploy as ROOT.war? Thanks

If I export as ROOT.war and deploy from command line it works

You can try using the tomcat plugin to do so with the following configuration:-
<plugin>
    <groupId>org.apache.tomcat.maven</groupId>
    <artifactId>tomcat-maven-plugin</artifactId>
    <version>2.2</version>
<configuration>
<path>/</path> <!-- root folder currently -->
</configuration>
</plugin>

This trick worked for me:
Before
After

I had exactly the same issue, and spend lots of time trying to find the solution. Eventually, I solved it so I'm posting the answer here so that my future self may find it again if required!
The m2e WTP integration uses a different property for the name it gives the target war file. See M2E-WTP-FAQ for details.
Add the following code to pom.xml
<properties>
<!-- Eclipse will use this value when auto-deploying into Tomcat -->
<m2eclipse.wtp.contextRoot>/</m2eclipse.wtp.contextRoot>
...
<build>
<!-- Maven (and build servers) will use this value when building war -->
<finalName>ROOT</finalName>
...
</build>
</properties>

How to update neo4j from 2.1.5 to 2.2.3 in Spring?

I needed to update my neo4j community from version 2.1.5 to version 2.2.3 to use it's new features.
I worked with it and create database in it.
Now, when I'm trying to run my Spring project, I'm getting an errors:
Caused by: org.neo4j.kernel.impl.storemigration.StoreUpgrader$UnexpectedUpgradingStoreVersionException: 'neostore.nodestore.db' has a store version number that we cannot upgrade from. Expected 'v0.A.1' but file is version 'NodeStore v0.A.5'.

In my pom.xml I changed spring-neo4j.version from 3.2.2.RELEASE to 3.3.1.RELEASE
After updating of project in Maven dependencies neo4j-files has version 2.1.7 but I need 2.2.3. How can I update dependencies in right way?

Use SDN 3.3.2 which is to be released today or tomorrow.
Then you can depend on org.neo4j:neo4j:2.2.3 and it should work.

How can i solve this problem ?

If your scope is provided I would think you would be expecting that dependency to come from a server resource. If that's the way you would deploy this in the end, you could try adding that jar to your server lib.

How can i solve this problem ?
Here's how >>you<< can solve this problem.
Look at the stacktrace to find the FQN for the class that is missing.
Use the findjar service to identify the public JARs that include the class you need.
Do some simple research to figure out an appropriate version. For example, identify and visit the corresponding developer website and see what they recommend as maven dependencies.
Add or modify a dependency in your POM file.
Repeat as required.

javax.persistence.EntityManager missing a method

I have recently tired to fix the problem with maven dependencies in my java web project and I deleted all things from the repository folder, after that I did "maven update project" in eclipse and the problem was fixed, however other error appeared. The method I was using createNamedQuery(String, Class<T>) no longer exists in the javax.persistence.EntityManager interface. I did some research and I suspect that maven has changed the JPA implementation version to JPA 1.0 which is very annoying and also I don't really know how to fix this. I didn't change anything in pom.xml, the only change that I noticed is that javax.persistence package now comes from ejb3 jar from jboss-as-connector maven artifact. How can I fix this?
SORRY: I just found out that the ejb3-persistence comes from hibernate package.

For this error, there can be different solutions. I have noted down the ones that had worked for me.
Solution 1. This is always happened in deployment and debugging environment. In deployment environment, just make sure your server classpath has included the Spring jar library (e.g spring-4.0.4.jar).
In debugging environment, the steps may vary from different IDE, but the solution is same. In Eclipse, developers usually will create a tomcat, jboss…whatever application server for debugging, just make sure the correct Spring jars are included.
Double click on your debugging server Click on the “Open launch
configuration” to access the server environment Click on the classpath tab Include the Spring jar file here , it may also
required common log jar due to Spring dependency.
Done, run your
application again.
.
Solution 2. If you are using Maven as a build tool and downloading dependencies using it, there can be some jar conflict. Because Tomcat servers normally provide some jars such as servlet-api and jpa-api. So if you again included them using maven; there will be problems in identifying them.
Solution 3. If you are using Eclipse as your IDE and using Maven as your build tool and tomcat as your server; remember Tomcat server will not look on the jars which are just inside the folders. For that there's a small trick,
Right click on your project and select properties From the displayed window,
select Deployment Assembly
Select Add
Add Maven dependencies
Click Apply and Click OK
Hope one of these solutions would help you to solve your problem. Happy Coding and make sure that is using Java.

In eclipse -> Your Project -> Properties -> Java Build Path -> Order and Export -> check Maven Dependencies.
Or in WebProject -> Your Project -> Properties -> Deployment assambly -> check Maven Dependencies.
This work in my case.

I had the same issue, but I fixed by adding Maven Dependencies. It was missing for some reason, and I have no clue

I have faced a similar issue with the same exception "java.lang.ClassNotFoundException: org.springframework.web.context.request.RequestContextListener".
It fixed after adding one dummy class in the src/main/java folder, and I really didn't know how this did the trick, it works for me.
