java spring hibernate maven spring-mvc

Solution 1

You have version conflicts in your dependencies.

You first include org.hibernate:hibernate:3.1.3, and then org.hibernate:hibernate-core:4.1.9.Final in your POM. You should decide, which version of Hibernate you want. Even if the artifact names are different of these artifacts, they might hold some classes with the same name and different implementations, which can cause your problem.

Solution 2

First of all, I don't see any hibernate.cfg file in your project.

create that file and replace the code in your servlet-context with this:

<beans:bean id="sessionFactory"
        class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
        <beans:property name="dataSource" ref="dataSource" />
        <beans:property name="configLocation">
            <beans:value>classpath:hibernate.cfg.xml</beans:value>
        </beans:property>
        <beans:property name="configurationClass">
            <beans:value>org.hibernate.cfg.AnnotationConfiguration</beans:value>
        </beans:property>
        <beans:property name="hibernateProperties">
            <beans:props>
                <beans:prop key="hibernate.dialect">${jdbc.dialect}</beans:prop>
                <beans:prop key="hibernate.show_sql">true</beans:prop>
            </beans:props>
        </beans:property>
    </beans:bean>

Add these dependancies:

I'm have little bit knowledge in spring, now i'm trying to integrate hibernate with spring, in my project i'm using below things. hibernate, spring, maven, mysql. while using these thing i'm getting IncompatibleClassChnageError before integrate hibernate its working fine and if i remove the hibernate configuration in configuration xml file then also its working fine

I think that's problem with dependacies ( I'm not able to understand which hibernate versions are correct for spring 3.1.2) Please any one help me, i'm giving my all files.
