Stubber 类型中的 when(T) 方法不适用于参数 (void)

The method when(T) in the type Stubber is not applicable for the arguments (void)

我在存根 void 时遇到以下错误:

The method when(T) in the type Stubber is not applicable for the arguments (void)

这是我的示例代码:

doNothing().when(mockRegistrationPeristImpl.create(any(Registration.class)));

public void create(final T record) throws DataAccessException {
    try {
        entityManager.persist(record);
        entityManager.flush();
    } catch (PersistenceException ex) {}
}

我错过了什么?

你的括号放错了,试试这个:

doNothing().when(mockRegistrationPeristImpl).create(any(Registration.class));
