Setting up a Spring JPA project for use in an MVC project - Error creating bean

jpa

I developed a Spring JPA project in eclipse which has access to the data stored in a mysql server. Now I need to import this project in a Spring @ MVC project. So:

  • I configure in the build path of the JPA project to export the maven dependencies
  • I added the project to the tomcat bootstrap class path,
  • I added the JPA/Spring project to the classpath of my Spring @MVC project
  • I also added the jpa application context to the root-context of the MVC project.

When I try to run the application on the tomcat server and I get an error. It seems that I the spring-beans library is missing but as you can see in the pom configuration I imported it. Here is the error log:

In my case the conflict was caused by spring security, which was still using older versions. I put some excludes on it, and now it is ok. It may also be a good thing to put this stuff in the dependencyManagement so you don't have to repeat in every module.

I am using the following:

<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-context-support</artifactId>

            <artifactId>spring-security-core</artifactId>

</dependencyManagement>

without the exclusions I had the same error as described in the beginning of this thread. The versions i was using for spring were:

<properties>
    <spring.framework.version>3.1.1.RELEASE</spring.framework.version>
    <spring.security.framework.version>3.1.0.RELEASE</spring.security.framework.version>
</properties>

I have had the same problem, and it turned out there was indeed a version mismatch, the problem with mine was that i used a server variable, in the form of ${server.env}, and it was this that gave the problem. Since my spring-expression version was 3.0.5 still. You should try adding these to your pom : 

        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-expression</artifactId>
            <version>${version.spring.framework}</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-beans</artifactId>
            <version>${version.spring.framework}</version>
        </dependency>
