Usage

From source file:org.jdbcluster.dao.Dao.java

/**

public static Object newInstance(Class<?> daoClass) {
    Object dao = JDBClusterUtil.createClassObject(daoClass);
    //get property of DAO and initial value from jdbcluster.dao.conf.xml
    HashMap<String, String> hm;
    synchronized (classToPropsMap) {
        hm = classToPropsMap.get(daoClass);
        if (hm == null)

    }

    BeanWrapper beanWrapper = new BeanWrapperImpl();

    for (String prop : hm.keySet()) {
        String value = hm.get(prop);
        //get property of DAO
        Class<?> propClass = beanWrapper.getPropertyType(prop);
        //convert to Type if necessary
        Object o = beanWrapper.convertIfNecessary(value, propClass);
        //set the value of the predefined property read from jdbcluster.dao.conf.xml
        beanWrapper.setPropertyValue(new PropertyValue(prop, o));
