Constructor Detail
AbstractUrlBasedView
protected AbstractUrlBasedView()
Constructor for use as a bean.
AbstractUrlBasedView

Create a new AbstractUrlBasedView with the given URL.- Parameters:
url- the URL to forward to
Method Detail
setUrl
public void setUrl(String url)

afterPropertiesSet
public void afterPropertiesSet() throws Exception

- Specified by:
afterPropertiesSetin interfaceInitializingBean- Throws:
Exception- in the event of misconfiguration (such as failure to set an essential property) or if initialization fails for any other reason
isUrlRequired
protected boolean isUrlRequired()
