public class InternalResourceViewResolver
extends UrlBasedViewResolver

Convenient subclass of UrlBasedViewResolver that supports InternalResourceView (i.e. Servlets and JSPs) and subclasses such as JstlView.

The view class for all views generated by this resolver can be specified via UrlBasedViewResolver.setViewClass(java.lang.Class<?>). See UrlBasedViewResolver's javadoc for details. The default is InternalResourceView, or JstlView if the JSTL API is present.

BTW, it's good practice to put JSP files that just serve as views under WEB-INF, to hide them from direct access (e.g. via a manually entered URL). Only controllers will be able to access them then.

Note: When chaining ViewResolvers, an InternalResourceViewResolver always needs to be last, as it will attempt to resolve any view name, no matter whether the underlying resource actually exists.

从以下版本开始:

4.0

构造器

构造器	说明
InternalResourceViewResolver()	Sets the default view class to requiredViewClass(): by default InternalResourceView, or JstlView if the JSTL API is present.
InternalResourceViewResolver(String prefix, String suffix)	A convenience constructor that allows for specifying prefix and suffix as constructor arguments.

protected AbstractUrlBasedView	buildView(String viewName)	Creates a new View instance of the specified view class and configures it.
protected AbstractUrlBasedView	instantiateView()	Instantiate the specified view class.
protected Class<?>	requiredViewClass()	Return the required type of view for this resolver.
void	setAlwaysInclude(boolean alwaysInclude)	Specify whether to always include the view rather than forward to it.

构造器详细资料

InternalResourceViewResolver

public InternalResourceViewResolver()

Sets the default view class to requiredViewClass(): by default InternalResourceView, or JstlView if the JSTL API is present.

InternalResourceViewResolver

public InternalResourceViewResolver(String prefix,
 String suffix)

A convenience constructor that allows for specifying prefix and suffix as constructor arguments.

参数:

prefix - the prefix that gets prepended to view names when building a URL

suffix - the suffix that gets appended to view names when building a URL

方法详细资料

setAlwaysInclude

public void setAlwaysInclude(boolean alwaysInclude)

Specify whether to always include the view rather than forward to it.

Default is "false". Switch this flag on to enforce the use of a Servlet include, even if a forward would be possible.

另请参阅:

• InternalResourceView.setAlwaysInclude(boolean)

requiredViewClass

protected Class<?> requiredViewClass()

从类复制的说明: UrlBasedViewResolver

Return the required type of view for this resolver. This implementation returns AbstractUrlBasedView.

覆盖:

requiredViewClass 在类中 UrlBasedViewResolver

另请参阅:

• UrlBasedViewResolver.instantiateView()
• AbstractUrlBasedView

instantiateView

protected AbstractUrlBasedView instantiateView()

从类复制的说明: UrlBasedViewResolver

Instantiate the specified view class.

The default implementation uses reflection to instantiate the class.

覆盖:

instantiateView 在类中 UrlBasedViewResolver

返回:

a new instance of the view class

另请参阅:

• UrlBasedViewResolver.setViewClass(java.lang.Class<?>)

buildView

protected AbstractUrlBasedView buildView(String viewName)
                                  throws Exception

从类复制的说明: UrlBasedViewResolver

Creates a new View instance of the specified view class and configures it. Does not perform any lookup for pre-defined View instances.

Framework lifecycle methods as defined by the bean container do not have to be called here; those will be applied by the loadView method after this method returns.

Subclasses will typically call super.buildView(viewName) first, before setting further properties themselves. loadView will then apply Framework lifecycle methods at the end of this process.

覆盖:

buildView 在类中 UrlBasedViewResolver

参数:

viewName - the name of the view to build

返回:

the View instance

抛出:

Exception - if the view couldn't be resolved
