所有已实现的接口:

```
public class ServletModelAttributeMethodProcessor
extends ModelAttributeMethodProcessor
```
A Servlet-specific ModelAttributeMethodProcessor that applies data binding through a WebDataBinder of type ServletRequestDataBinder.
Also adds a fall-back strategy to instantiate the model attribute from a URI template variable or from a request parameter if the name matches the model attribute name and there is an appropriate type conversion strategy.

修饰符和类型	方法	说明
`protected void`	`bindRequestParameters(WebDataBinder binder, NativeWebRequest request)`	This implementation downcasts `WebDataBinder` to `ServletRequestDataBinder` before binding.
`protected Object`	`createAttribute(String attributeName, MethodParameter parameter, WebDataBinderFactory binderFactory, NativeWebRequest request)`	Instantiate the model attribute from a URI template variable or from a request parameter if the name matches to the model attribute name and if there is an appropriate type conversion strategy.
`protected Object`	`createAttributeFromRequestValue(String sourceValue, String attributeName, MethodParameter parameter, WebDataBinderFactory binderFactory, NativeWebRequest request)`	Create a model attribute from a String request value (e.g.
`protected String`	`getRequestValueForAttribute(String attributeName, NativeWebRequest request)`	Obtain a value from the request that may be used to instantiate the model attribute through type conversion from String to the target type.

```
public ServletModelAttributeMethodProcessor(boolean annotationNotRequired)
```
    Class constructor.
    参数:
    annotationNotRequired - if "true", non-simple method arguments and return values are considered model attributes with or without a @ModelAttribute annotation

```
protected final Object createAttribute(String attributeName,
                                       MethodParameter parameter,
                                       WebDataBinderFactory binderFactory,
                                       NativeWebRequest request)
                                throws Exception
```
    Instantiate the model attribute from a URI template variable or from a request parameter if the name matches to the model attribute name and if there is an appropriate type conversion strategy. If none of these are true delegate back to the base class.
    覆盖:
    createAttribute 在类中 ModelAttributeMethodProcessor
    参数:
    attributeName - the name of the attribute (never null)
    parameter - the method parameter
    binderFactory - for creating WebDataBinder instance
    request - the current request
    返回:
    the created model attribute (never null)
    抛出:
    Exception
    另请参阅:
    createAttributeFromRequestValue(java.lang.String, java.lang.String, org.springframework.core.MethodParameter, org.springframework.web.bind.support.WebDataBinderFactory, org.springframework.web.context.request.NativeWebRequest)
  - getRequestValueForAttribute
```
protected String getRequestValueForAttribute(String attributeName,
                                             NativeWebRequest request)
```
    Obtain a value from the request that may be used to instantiate the model attribute through type conversion from String to the target type.
    The default implementation looks for the attribute name to match a URI variable first and then a request parameter.
    参数:
    attributeName - the model attribute name
    request - the current request
    返回:
    the request value to try to convert, or null if none
  - getUriTemplateVariables
```
protected final Map<String,String> getUriTemplateVariables(NativeWebRequest request)
```
  - createAttributeFromRequestValue
```
protected Object createAttributeFromRequestValue(String sourceValue,
                                                 String attributeName,
                                                 MethodParameter parameter,
                                                 WebDataBinderFactory binderFactory,
                                                 NativeWebRequest request)
                                          throws Exception
```
    Create a model attribute from a String request value (e.g. URI template variable, request parameter) using type conversion.
    The default implementation converts only if there a registered Converter that can perform the conversion.
    参数:
    sourceValue - the source value to create the model attribute from
    attributeName - the name of the attribute (never null)
    parameter - the method parameter
    binderFactory - for creating WebDataBinder instance
    request - the current request
    返回:
    the created model attribute, or null if no suitable conversion found
    抛出:
    Exception
  - bindRequestParameters
```
protected void bindRequestParameters(WebDataBinder binder,
                                     NativeWebRequest request)
```
    This implementation downcasts WebDataBinder to ServletRequestDataBinder before binding.
    覆盖:
    bindRequestParameters 在类中 ModelAttributeMethodProcessor
    参数:
    binder - the data binder instance to use for the binding
    request - the current request
