The application context file of Spring:

Code:

    </bean>

    <bean id="gov.mohr.ems.core.entity.logic.DefaultQueryMethod" class="gov.mohr.ems.core.entity.logic.DefaultQueryMethod"/>
   
</beans>


The implementation of the file from test case:

Code:
...

public class DefaultQueryMethodTest
    extends AbstractDependencyInjectionSpringContextTests {
    private static final String[] CONFIG_LOCATIONS = new String[] {
                                                         "/applicationcontext.xml"
                                                     };
    protected Log log = LogFactory.getLog(DefaultQueryMethodTest.class);

    /**
     * Returns the applicationcontext.xml locations
     */
    protected String[] getConfigLocations() {
        return CONFIG_LOCATIONS;
    }

    public void testSingleOperatorEqual() {
        log.info("running DefaultQueryMethodTest.testSingleOperatorEqual()");

        QueryMethod defaultQueryMethod = (DefaultQueryMethod) applicationContext.getBean(DefaultQueryMethod.class.getName());
        QueryCriteria queryCriteria = new QueryCriteria();
        Condition condition = new Condition();
        condition.setProperty("statusCode");
        condition.setOperator(Condition.OPERATOR_EQUAL);
        condition.setValue("O");

        List<Condition> conditionList = new ArrayList<Condition>();
        conditionList.add(condition);
        queryCriteria.setConditions(conditionList);
        queryCriteria.setEntityName("RefActivityStatus");

        List result = new ArrayList();

        try {
            result = defaultQueryMethod.executeQuery(queryCriteria);
        } catch (IllegalAccessException e) {
            log.error(e.getMessage());
            e.printStackTrace();
        } catch (NoSuchMethodException e) {
            log.error(e.getMessage());
            e.printStackTrace();
        } catch (InvocationTargetException e) {
            log.error(e.getMessage());
            e.printStackTrace();
        } finally {
            if ((null != result) && (result.size() > 0)) {
                log.info(result.size());
                System.out.print((RefActivityStatus) result.get(0));
            }
        }
    }
}


And this is the implementation of the logic of DefaultQueryMethod.java

Code:
...

public class DefaultQueryMethod extends ImplSupport implements QueryMethod {
    /** Construct apache common log method */
    protected Log log = LogFactory.getLog(DefaultQueryMethod.class);

    /* To store local match mode matching **/
    private Map matchModeMap = new HashMap();

/** Creates a new instance of DefaultQueryMethod */
    public DefaultQueryMethod() {
        matchModeMap.put(Condition.MATCH_MODE_ANYWHERE, MatchMode.ANYWHERE);
        matchModeMap.put(Condition.MATCH_MODE_END, MatchMode.END);
        matchModeMap.put(Condition.MATCH_MODE_EXACT, MatchMode.EXACT);
        matchModeMap.put(Condition.MATCH_MODE_START, MatchMode.START);
    }

    /**
     * The proper implementation of execute query
     */
    public List executeQuery(QueryCriteria queryCriteria)
                      throws IllegalAccessException, NoSuchMethodException,
                             InvocationTargetException {
        log.info("executeQuery(QueryCriteria queryCriteria)");

        Session sess = getSession();
        Criteria criteria = sess.createCriteria(queryCriteria.getEntityName());

        if (queryCriteria.getConditions().size() > 0) {
            List criteriaList = queryCriteria.getConditions();
            Iterator it = criteriaList.iterator();

            while (it.hasNext()) {
                Condition condition = (Condition) it.next();

                if (null != condition.getValue()) {
                    if (condition.getOperator().equals(Condition.OPERATOR_ILIKE) &&
                        (null != condition.getMatchMode())) {
                        criteria.add(Restrictions.ilike(condition.getProperty(),
                                                        (String) condition.getValue(),
                                                        (MatchMode) matchModeMap.get(condition.getMatchMode())));
                    } else if (condition.getOperator()
                                        .equals(Condition.OPERATOR_LIKE) &&
                               (null != condition.getMatchMode())) {
                        criteria.add(Restrictions.like(condition.getProperty(),
                                                       (String) condition.getValue(),
                                                       (MatchMode) matchModeMap.get(condition.getMatchMode())));
                    } else {

                                                                  new Class[] {
                                                                      String.class,
                                                                      Object.class
                                                                  });
                        Criterion res = (Criterion) mtd.invoke(null,

                                                               });
                        criteria.add(res);
                    }
                }
            }
        }

        return criteria.list();
    }
}
