反射获取List中的泛型

获取List中的泛型类型，创建对象，并且字段设置值

for (Field f : partPropType.getDeclaredFields()) {            if ("accountPrincipalApproveList".equals(f.getName())) {                f.setAccessible(true);                List accountPrincipalApproveList = new ArrayList();                if(f.getType() == java.util.List.class){                    // 如果是List类型，得到其Generic的类型                    Type genericType = f.getGenericType();                    if(genericType == null) continue;                    // 如果是泛型参数的类型                    if(genericType instanceof ParameterizedType){                        ParameterizedType pt = (ParameterizedType) genericType;                        //得到泛型里的class类型对象                        Class<?> accountPrincipalApproveClazz = (Class<?>)pt.getActualTypeArguments()[0];                        Object accountPrincipalApprove = accountPrincipalApproveClazz.newInstance();                        PropertyDescriptor acctApproveIdPropertyDescriptor = new PropertyDescriptor("acctApproveId", accountPrincipalApproveClazz);                        acctApproveIdPropertyDescriptor.getWriteMethod().invoke(inputPartObject, "ACCOUNT_TYPE_NONE");                        accountPrincipalApproveList.add(accountPrincipalApprove);                    }                }                f.set(inputPartObject,accountPrincipalApproveList);                break;            }        }
