## org.springframework.web.servlet.view.xslt
Class AbstractXsltView

    java.lang.Object
      org.springframework.context.support.ApplicationObjectSupport
          org.springframework.web.context.support.WebApplicationObjectSupport
              org.springframework.web.servlet.view.AbstractView
                  org.springframework.web.servlet.view.xslt.AbstractXsltView

All Implemented Interfaces:
  Aware, BeanNameAware, ApplicationContextAware, ServletContextAware, View

Deprecated. since Spring 2.5; superseded by `XsltView` and its more flexible `XsltView.locateSource(java.util.Map)` mechanism

    @Deprecated
    public abstract class AbstractXsltView

extends AbstractView

Convenient superclass for views rendered using an XSLT stylesheet.

Subclasses typically must provide the `Source` to transform by overriding `createXsltSource(java.util.Map, java.lang.String, javax.servlet.http.HttpServletRequest, javax.servlet.http.HttpServletResponse)`. Subclasses do not need to concern themselves with XSLT other than providing a valid stylesheet location.

Properties:

- `stylesheetLocation`: a `Resource` pointing to the XSLT stylesheet
- `root`: the name of the root element; defaults to `"DocRoot"`
- `uriResolver`: the `URIResolver` to be used in the transform
- `errorListener` (optional): the `ErrorListener` implementation instance for custom handling of warnings and errors during TransformerFactory operations
- `indent` (optional): whether additional whitespace may be added when outputting the result; defaults to `true`
- `cache` (optional): are templates to be cached; debug setting only; defaults to `true`

Note that setting `"cache"` to `false` will cause the template objects to be reloaded for each rendering. This is useful during development, but will seriously affect performance in production and is not thread-safe.

  Deprecated.
  The default document root name

  See Also:
    Constant Field Values

Constructor Detail

### AbstractXsltView

    protected AbstractXsltView()

  Deprecated.
  This constructor sets the content type to "text/xml;charset=ISO-8859-1" by default. This will be switched to the standard web view default "text/html;charset=ISO-8859-1" if a stylesheet location has been specified.

  A specific content type can be configured via the `"contentType"` bean property.

Method Detail

### setContentType

    public void setContentType(String contentType)

  Deprecated.
  Description copied from class: `AbstractView`
  Set the content type for this view. Default is "text/html;charset=ISO-8859-1".

  May be ignored by subclasses if the view itself is assumed to set the content type, e.g. in case of JSPs.

  Overrides:
    `setContentType` in class `AbstractView`

### setTransformerFactoryClass

    public void setTransformerFactoryClass(Class transformerFactoryClass)

  Deprecated.
  Specify the XSLT TransformerFactory class to use.

  The default constructor of the specified class will be called to build the TransformerFactory for this view.

### setStylesheetLocation

    public void setStylesheetLocation(Resource stylesheetLocation)

  Deprecated.
  Set the location of the XSLT stylesheet.

  If the `TransformerFactory` used by this instance has already been initialized then invoking this setter will result in the `attendant templates` being re-cached.

  Parameters:
    `stylesheetLocation` - the location of the XSLT stylesheet
  See Also:
    `ResourceLoader.getResource(java.lang.String)`

### getStylesheetLocation

    protected Resource getStylesheetLocation()

  Deprecated.
  Return the location of the XSLT stylesheet, if any.

### setRoot

    public void setRoot(String root)

  Deprecated.
  The document root element name. Default is `"DocRoot"`.

  Only used if we're not passed a single `Node` as the model.

  Parameters:
    `root` - the document root element name
  See Also:
    `DEFAULT_ROOT`

### setUseSingleModelNameAsRoot

    public void setUseSingleModelNameAsRoot(boolean useSingleModelNameAsRoot)

  Deprecated.
  Set whether to use the name of a given single model object as the document root element name.

  Default is `true` : If you pass in a model with a single object named "myElement", then the document root will be named "myElement" as well. Set this flag to `false` if you want to pass in a single model object while still using the root element name configured through the `"root" property`.

  Parameters:
    `useSingleModelNameAsRoot` - `true` if the name of a given single model object is to be used as the document root element name
  See Also:
    `setRoot(java.lang.String)`

### setUriResolver

    public void setUriResolver(URIResolver uriResolver)

  Deprecated.
  Set the URIResolver used in the transform.

  The URIResolver handles calls to the XSLT `document()` function.

### setErrorListener

    public void setErrorListener(ErrorListener errorListener)

  Deprecated.
  Set an implementation of the `ErrorListener` interface for custom handling of transformation errors and warnings.

  If not set, a default `SimpleTransformErrorListener` is used that simply logs warnings using the logger instance of the view class, and rethrows errors to discontinue the XML transformation.

  See Also:
    `SimpleTransformErrorListener`

### setIndent

    public void setIndent(boolean indent)

  Deprecated.
  Set whether the XSLT transformer may add additional whitespace when outputting the result tree.

  Default is `true` (on); set this to `false` (off) to not specify an "indent" key, leaving the choice up to the stylesheet.

  See Also:
    `OutputKeys.INDENT`

### setOutputProperties

    public void setOutputProperties(Properties outputProperties)

  Deprecated.
  Set arbitrary transformer output properties to be applied to the stylesheet.

  Any values specified here will override defaults that this view sets programmatically.

  See Also:
    `Transformer.setOutputProperty(java.lang.String, java.lang.String)`

### setCache

    public void setCache(boolean cache)

  Deprecated.
  Set whether to activate the template cache for this view.

  Default is `true`. Turn this off to refresh the Templates object on every access, e.g. during development.

  See Also:
    `resetCachedTemplates()`

### resetCachedTemplates

    public final void resetCachedTemplates()

  Deprecated.
  Reset the cached Templates object, if any.

  The Templates object will subsequently be rebuilt on next `access`, if caching is enabled.

  See Also:
    `setCache(boolean)`

### initApplicationContext

    protected final void initApplicationContext()
                                         throws ApplicationContextException

  Deprecated.
  Here we load our template, as we need the `ApplicationContext` to do it.

  Overrides:
    `initApplicationContext` in class `ApplicationObjectSupport`
  Throws:
    `ApplicationContextException` - in case of initialization errors
  See Also:
    `ApplicationObjectSupport.setApplicationContext(org.springframework.context.ApplicationContext)`

### newTransformerFactory

    protected TransformerFactory newTransformerFactory(Class transformerFactoryClass)

  Deprecated.
  Instantiate a new TransformerFactory for this view.

  The default implementation simply calls `TransformerFactory.newInstance()`. If a `"transformerFactoryClass"` has been specified explicitly, the default constructor of the specified class will be called instead.

  Can be overridden in subclasses.

  Parameters:
    `transformerFactoryClass` - the specified factory class (if any)
  Returns:
    the new TransactionFactory instance
  Throws:
    `TransformerFactoryConfigurationError` - in case of instantiation failure
  See Also:
    `setTransformerFactoryClass(java.lang.Class)`, `getTransformerFactory()`

### getTransformerFactory

    protected final TransformerFactory getTransformerFactory()

  Deprecated.
  Return the TransformerFactory used by this view. Available once the View object has been fully initialized.

### renderMergedOutputModel

    protected final void renderMergedOutputModel(Map<String,Object> model,
                                                 HttpServletRequest request,
                                                 HttpServletResponse response)
                                          throws Exception

  Deprecated.
  Description copied from class: `AbstractView`
  Subclasses must implement this method to actually render the view.

  The first step will be preparing the request: In the JSP case, this would mean setting model objects as request attributes. The second step will be the actual rendering of the view, for example including the JSP via a RequestDispatcher.

  Specified by:
    `renderMergedOutputModel` in class `AbstractView`
  Parameters:
    `model` - combined output Map (never `null`), with dynamic values taking precedence over static attributes
    `request` - current HTTP request
    `response` - current HTTP response
  Throws:
    `Exception` - if rendering failed

### createXsltSource

    protected Source createXsltSource(Map<String,Object> model,
                                      String root,
                                      HttpServletRequest request,
                                      HttpServletResponse response)
                               throws Exception

  Deprecated.
  Return the XML `Source` to transform.

  Parameters:
    `model` - the model Map
    `root` - name for root element. This can be supplied as a bean property to concrete subclasses within the view definition file, but will be overridden in the case of a single object in the model map to be the key for that object. If no root property is specified and multiple model objects exist, a default root tag name will be supplied.
    `request` - HTTP request. Subclasses won't normally use this, as request processing should have been complete. However, we might want to create a RequestContext to expose as part of the model.
    `response` - HTTP response. Subclasses won't normally use this, however there may sometimes be a need to set cookies.
  Returns:
    the XSLT Source to transform
  Throws:
    `Exception` - if an error occurs

### doTransform

    protected void doTransform(Map<String,Object> model,
                               Source source,

                               HttpServletResponse response)
                        throws Exception

  Deprecated.
  Perform the actual transformation, writing to the HTTP response.

  The default implementation delegates to the `doTransform(javax.xml.transform.Source, java.util.Map, javax.xml.transform.Result, String)` method, building a StreamResult for the ServletResponse OutputStream or for the ServletResponse Writer (according to `useWriter()`).

  Parameters:
    `model` - the model Map
    `source` - the Source to transform
    `request` - current HTTP request
    `response` - current HTTP response
  Throws:
    `Exception` - if an error occurs
  See Also:
    `StreamResult`, `ServletResponse.getOutputStream()`, `ServletResponse.getWriter()`, `useWriter()`

                                HttpServletRequest request)

  Deprecated.
  Return a Map of transformer parameters to be applied to the stylesheet.

  Subclasses can override this method in order to apply one or more parameters to the transformation process.

  The default implementation delegates to the `getParameters(HttpServletRequest)` variant.

  Parameters:
    `model` - the model Map
    `request` - current HTTP request
  Returns:
    a Map of parameters to apply to the transformation process
  See Also:

  Returns:
    a Map of parameters to apply to the transformation process
  See Also:
    `getParameters(Map, HttpServletRequest)`, `Transformer.setParameter(java.lang.String, java.lang.Object)`

### useWriter

    protected boolean useWriter()

  Deprecated.
  Return whether to use a `java.io.Writer` to write text content to the HTTP response. Else, a `java.io.OutputStream` will be used, to write binary content to the response.

  The default implementation returns `false`, indicating a a `java.io.OutputStream`.

  Returns:
    whether to use a Writer (`true`) or an OutputStream (`false`)
  See Also:
    `ServletResponse.getWriter()`, `ServletResponse.getOutputStream()`

### doTransform

    protected void doTransform(Source source,
                               Map<String,Object> parameters,

                        throws Exception

  Deprecated.
  Perform the actual transformation, writing to the given result.

  Parameters:
    `source` - the Source to transform
    `parameters` - a Map of parameters to be applied to the stylesheet (as determined by `getParameters(Map, HttpServletRequest)`)

  Deprecated.
  Obtain the Templates object to use, based on the configured stylesheet, either a cached one or a freshly built one.

  Subclasses may override this method e.g. in order to refresh the Templates instance, calling `resetCachedTemplates()` before delegating to this `getTemplates()` implementation.

  Returns:
    the Templates object (or `null` if there is no stylesheet specified)
