Java获取泛型的Class对象

工作中瞄到的，在此收集了

[java] view plain copy

public class RawDao<T> {

protected Class<T> clazz;

@SuppressWarnings("unchecked")

public RawDao() {

@SuppressWarnings("rawtypes")

Class clazz = getClass();

while (clazz != Object.class) {

Type t = clazz.getGenericSuperclass();

if (t instanceof ParameterizedType) {

Type[] args = ((ParameterizedType) t).getActualTypeArguments();

if (args[0] instanceof Class) {

this.clazz = (Class<T>) args[0];

break;

}

}

clazz = clazz.getSuperclass();

}

}
