public class InternalResourceView
extends AbstractUrlBasedView
```
Wrapper for a JSP or other resource within the same web application. Exposes model objects as request attributes and forwards the request to the specified resource URL using a RequestDispatcher.
A URL for this view is supposed to specify a resource within the web application, suitable for RequestDispatcher's forward or include method.
If operating within an already included request or within a response that has already been committed, this view will fall back to an include instead of a forward. This can be enforced by calling response.flushBuffer() (which will commit the response) before rendering the view.
Typical usage with InternalResourceViewResolver looks as follows, from the perspective of the DispatcherServlet context definition:
```
<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
   <property name="prefix" value="/WEB-INF/jsp/"/>
   <property name="suffix" value=".jsp"/>
 </bean>
```
Every view name returned from a handler will be translated to a JSP resource (for example: "myView" -> "/WEB-INF/jsp/myView.jsp"), using this view class by default.

```
public InternalResourceView()
```
    Constructor for use as a bean.
    另请参阅:
    AbstractUrlBasedView.setUrl(java.lang.String), setAlwaysInclude(boolean)
  - InternalResourceView
```
public InternalResourceView(String url)
```
    Create a new InternalResourceView with the given URL.
    参数:
    url - the URL to forward to
    另请参阅:
    setAlwaysInclude(boolean)
  - InternalResourceView
```
public InternalResourceView(String url,
                            boolean alwaysInclude)
```
    Create a new InternalResourceView with the given URL.
    参数:
    url - the URL to forward to
    alwaysInclude - whether to always include the view rather than forward to it
- 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:
    RequestDispatcher.forward(javax.servlet.ServletRequest, javax.servlet.ServletResponse), RequestDispatcher.include(javax.servlet.ServletRequest, javax.servlet.ServletResponse), useInclude(javax.servlet.http.HttpServletRequest, javax.servlet.http.HttpServletResponse)
  - setPreventDispatchLoop
```
public void setPreventDispatchLoop(boolean preventDispatchLoop)
```
    Set whether to explicitly prevent dispatching back to the current handler path.
    Default is "false". Switch this to "true" for convention-based views where a dispatch back to the current handler path is a definitive error.
  - isContextRequired
```
protected boolean isContextRequired()
```
    An ApplicationContext is not strictly required for InternalResourceView.
    覆盖:
    isContextRequired 在类中 WebApplicationObjectSupport

    ApplicationObjectSupport.getApplicationContext(), ApplicationObjectSupport.getMessageSourceAccessor(), WebApplicationObjectSupport.getWebApplicationContext(), WebApplicationObjectSupport.getServletContext(), WebApplicationObjectSupport.getTempDir()
  - renderMergedOutputModel
```
protected void renderMergedOutputModel(Map<String,Object> model,
                                       HttpServletRequest request,
                                       HttpServletResponse response)
                                throws Exception
```
    Render the internal resource given the specified model. This includes setting the model as request attributes.
    指定者:
    renderMergedOutputModel 在类中 AbstractView
    参数:
    model - combined output Map (never null), with dynamic values taking precedence over static attributes
    request - current HTTP request
    response - current HTTP response
    抛出:
    Exception - if rendering failed
  - exposeHelpers
```
protected void exposeHelpers(HttpServletRequest request)
                      throws Exception
```
    Expose helpers unique to each rendering operation. This is necessary so that different rendering operations can't overwrite each other's contexts etc.
    Called by renderMergedOutputModel(Map, HttpServletRequest, HttpServletResponse). The default implementation is empty. This method can be overridden to add custom helpers as request attributes.
    参数:
    request - current HTTP request
    抛出:
    Exception - if there's a fatal error while we're adding attributes
    另请参阅:
    renderMergedOutputModel(java.util.Map<java.lang.String, java.lang.Object>, javax.servlet.http.HttpServletRequest, javax.servlet.http.HttpServletResponse), JstlView.exposeHelpers(javax.servlet.http.HttpServletRequest)
  - prepareForRendering
```
protected String prepareForRendering(HttpServletRequest request,
                                     HttpServletResponse response)
                              throws Exception
```
    Prepare for rendering, and determine the request dispatcher path to forward to (or to include).
    This implementation simply returns the configured URL. Subclasses can override this to determine a resource to render, typically interpreting the URL in a different manner.
    参数:
    request - current HTTP request
    response - current HTTP response
    返回:
    the request dispatcher path to use
    抛出:
    Exception - if preparations failed
    另请参阅:
    AbstractUrlBasedView.getUrl()
  - getRequestDispatcher
```
protected RequestDispatcher getRequestDispatcher(HttpServletRequest request,
                                                 String path)
```
    Obtain the RequestDispatcher to use for the forward/include.
    The default implementation simply calls ServletRequest.getRequestDispatcher(String). Can be overridden in subclasses.
    参数:
    request - current HTTP request
    path - the target URL (as returned from prepareForRendering(javax.servlet.http.HttpServletRequest, javax.servlet.http.HttpServletResponse))
    返回:
    a corresponding RequestDispatcher
  - useInclude
```
protected boolean useInclude(HttpServletRequest request,
                             HttpServletResponse response)
```
    Determine whether to use RequestDispatcher's include or forward method.
    Performs a check whether an include URI attribute is found in the request, indicating an include request, and whether the response has already been committed. In both cases, an include will be performed, as a forward is not possible anymore.
    参数:
    request - current HTTP request
    response - current HTTP response
    返回:
    true for include, false for forward
