public interface View
```
MVC View for a web interaction. Implementations are responsible for rendering content, and exposing the model. A single view exposes multiple model attributes.
This class and the MVC approach associated with it is discussed in Chapter 12 of Expert One-On-One J2EE Design and Development by Rod Johnson (Wrox, 2002).
View implementations may differ widely. An obvious implementation would be JSP-based. Other implementations might be XSLT-based, or use an HTML generation library. This interface is designed to avoid restricting the range of possible implementations.
Views should be beans. They are likely to be instantiated as beans by a ViewResolver. As this interface is stateless, view implementations should be thread-safe.

`String`	`getContentType()`	Return the content type of the view, if predetermined.

- 字段详细资料
  - RESPONSE_STATUS_ATTRIBUTE
```
static final String RESPONSE_STATUS_ATTRIBUTE
```
    Name of the HttpServletRequest attribute that contains the response status code.
    Note: This attribute is not required to be supported by all View implementations.
    从以下版本开始:
    3.0
  - PATH_VARIABLES
```
static final String PATH_VARIABLES
```
    Name of the HttpServletRequest attribute that contains a Map with path variables. The map consists of String-based URI template variable names as keys and their corresponding Object-based values -- extracted from segments of the URL and type converted.
    Note: This attribute is not required to be supported by all View implementations.
    从以下版本开始:
    3.1
  - SELECTED_CONTENT_TYPE
```
static final String SELECTED_CONTENT_TYPE
```
    The MediaType selected during content negotiation, which may be more specific than the one the View is configured with. For example: "application/vnd.example-v1+xml" vs "application/*+xml".
    从以下版本开始:
    3.2
- 方法详细资料
  - getContentType
```
String getContentType()
```
    Return the content type of the view, if predetermined.
    Can be used to check the view's content type upfront, i.e. before an actual rendering attempt.
    返回:
    the content type String (optionally including a character set), or null if not predetermined
  - render
```
void render(Map<String,?> model,
            HttpServletRequest request,
            HttpServletResponse response)
     throws Exception
```
    Render the view given the specified model.
    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.
    参数:
    model - Map with name Strings as keys and corresponding model objects as values (Map can also be null in case of empty model)
    request - current HTTP request
    response - HTTP response we are building
    抛出:
    Exception - if rendering failed
