javaspringmavenstruts2struts2-spring-plugin

java.lang.NoSuchMethodError: org.springframework.beans.support.ResourceEditorRegistrar.<init>

Trying to integrate Spring 4.2.2.RELEASE with Struts2 2.3.24.1. I had tested that Spring was working by manually instantiating my Service class inside the action as

ApplicationContext context = new ClassPathXmlApplicationContext("beans.xml");
DbServicesHibernate dbServices = (DbServicesHibernate) context.getBean("dbServices");

Once that worked, I wanted that spring injected the dbServices dependency automatically by autowiring, so I added the struts2-spring-plugin 2.3.24.1 and modified web.xml. The resulting files and error stack trace being:

struts.xml

I have been struggling with this integration for weeks, this time I though I was close but here I am, stuck once again...

Any idea on what might be causing this? is it some sort of incompatibility among the different libraries?

Solution

  • The maven dependency to struts2-spring-plugin : 2.3.24.1 includes a dependency on spring-web : 3.0.5.RELEASE which includes in turn a dependency on spring-beans : 3.0.5.RELEASE.

    So, spring-beans : 3.0.5.RELEASE was the reference used for the org.springframework.beans.support.ResourceEditorRegistrar class, which was not compatible with the rest of spring 4.2.2.RELEASE.

    I included the dependency on spring-beans : 4.2.2.RELEASE on top of my hierarchy i.e. on the pom.xml file as

    <dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-beans</artifactId>
    <version>4.2.2.RELEASE</version>
</dependency>

    and now the spring-beans 3.0.5.RELEASE linked through struts2-spring-plugin is no longer used and the spring-beans-4.2.2.RELEASE.jar file is included in the Maven dependencies.
