HashMap accessible from whole project

I have defined HashMap

<bean id="userMap" class="pl.test.pojo.UserMap">
    <property name="userMap">
        <map>
        </map>
    </property>
</bean>

I want to be able to access this content from any class in my project I write to it like:

@Autowired
UserMap userMap;
    Status s = new Status();
    User req = new User();
    s.setStatus(3);
    s.setErrorCode("0");
    s.setErrorDescription("OK");
    s.setCorrelationId(addToQuarantineRequest.getCorrelationId());
    userMap.getUserMap().put(req, s);

and it is ok, but from another class I want to read content of the userMap firstly declaring it with @autowired annotation I have got NullPointerException how can I make Map to be accesible from whole project?
