Весна - странная ошибка с отражением

2015-02-12 4 views

У меня есть Весна Бин, названная PortfolioBean, которая содержит метод getWorkItem(). В другом Bean я пытаюсь вызвать метод этого Бина:Весна - странная ошибка с отражением

PortfolioBean lastObjBean = (PortfolioBean) applicationContext.getBean(myAnnotation.parametersLastObjBeanName()); 
lastObjBean.getWorkTypeItem(7777);

И этот код работает отлично. Но когда я пытаюсь вызвать этот метод посредством отражения:

PortfolioBean lastObjBean = (PortfolioBean) applicationContext.getBean(myAnnotation.parametersLastObjBeanName()); 
String getSingleLastObjMethodName=myAnnotation.parametersLastObjBeanGetSingleObject(); 
System.out.println("getSingleLastObjMethodName "+getSingleLastObjMethodName);       
Method lastObjBeanGetObjMethod = lastObjBean.getClass() 
            .getMethod(getSingleLastObjMethodName);

я получил исключение:

getSingleLastObjMethodName getWorkTypeItem

Почему это исключение возникает, когда я пытаюсь получить этот метод с отражением?

getWorkTypeItem() не найден, потому что он получает int или long, и вы просите за getWorkTypeItem() метод, который не принимает никаких параметров.

Попробуйте с этим:

Method lastObjBeanGetObjMethod = lastObjBean.getClass().getMethod(getSingleLastObjMethodName, int.class);

Или long.class, если он получает длинный и т.д. Вы должны соответствовать подписи метода.
