Need help configuring MongoDB on Spring/Maven

Question

When I code in Spring, I always use annotations, and always get stuck when it comes to xml based configuration. Right now, I'm stuck at a problem which is probably a very simple thing. I'd appreciate if you could help me out on this.

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'mongoTemplate' defined in ServletContext resource [/WEB-INF/spring-servlet.xml]: Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Could not instantiate bean class [org.springframework.data.mongodb.core.MongoTemplate]: Constructor threw exception; nested exception is java.lang.IllegalAccessError: tried to access method org.springframework.core.GenericTypeResolver.getTypeVariableMap(Ljava/lang/Class;)Ljava/util/Map; from class org.springframework.data.util.ClassTypeInformation

An IllegalAccessError in compiled code (not involving reflection) usually means a version mismatch: Client code was compiled against a version of the dependency where a member had a more permissive access modifier. Update your Maven dependencies.

(Since this is a very old question that got recently bumped: The versions involved are all obsolete and should be upgraded to modern versions, which should resolve the problem.)

that, or there is a version mismatch in the spring jars themselves (mix of different versions of spring libraries). Without pom we can't know.

@eis All I'm saying is that some dependencies don't match, and updating everything should work.

    !.  Changes in Xml

    spring-servlet.xml you can also change name with spring-servlet.xml to yourProjectName-servlet.xml

        http://www.springframework.org/schema/data/mongo
          http://www.springframework.org/schema/data/mongo/spring-mongo-1.0.xsd

          change to 1.1

                  http://www.springframework.org/schema/data/mongo
        http://www.springframework.org/schema/data/mongo/spring-mongo-1.1.xsd



    <mongo:mongo host="localhost" port="27017">

    <mongo:options connections-per-host="100"
   threads-allowed-to-block-for-connection-multiplier="5"
            max-wait-time="120000000"
            connect-timeout="10000000"
            socket-keep-alive="true"
            socket-timeout="15000000"
            auto-connect-retry="true"/>

    </mongo:mongo>


    <mongo:db-factory dbname="jobstix"
        mongo-ref="mongo" />
    <bean id="mongoTypeMapper"
        class="org.springframework.data.mongodb.core.convert.DefaultMongoTypeMapper">
        <constructor-arg name="typeKey">
            <null />
        </constructor-arg>
    </bean>
    <bean id="mongoMappingContext"
        class="org.springframework.data.mongodb.core.mapping.MongoMappingContext" />
    <bean id="mongoConverter"
        class="org.springframework.data.mongodb.core.convert.MappingMongoConverter">
        <constructor-arg name="mongoDbFactory" ref="mongoDbFactory" />
        <constructor-arg name="mappingContext" ref="mongoMappingContext" />
        <property name="typeMapper" ref="mongoTypeMapper"></property>
    </bean>
    <bean id="mongoTemplate" class="org.springframework.data.mongodb.core.MongoTemplate">
        <constructor-arg name="mongoDbFactory" ref="mongoDbFactory" />
        <constructor-arg name="mongoConverter" ref="mongoConverter" />
        <property name="writeResultChecking" value="EXCEPTION" />
    </bean>

2. Put Four Jars OR Get From Maven

/Test/WebContent/WEB-INF/lib/mongo-java-driver-2.10.1.jar
/Test/WebContent/WEB-INF/lib/spring-data-commons-1.5.1.RELEASE.jar
/Test/WebContent/WEB-INF/lib/spring-data-commons-core-1.3.1.RELEASE.jar
/Test/WebContent/WEB-INF/lib/spring-data-mongodb-1.3.1.RELEASE.jar

3. In Dao/Service/Controller you can call these connection to Autowired

    @Autowired
    private MongoTemplate mongoTemplate;

    @Autowired
    private MongoOperations mongoOperation;
