Create a new InitBinderBindingContext instance.

参数:

initializer - for global data binder initialization

InitBinderBindingContext

InitBinderBindingContext(ModelHandler modelHandler,
 @Nullable
 WebBindingInitializer initializer,
 ControllerMethodResolver methodResolver,
 List<InvocableHandlerMethod> binderMethods,
 HandlerMethod handlerMethod)

Create a new InitBinderBindingContext instance.

参数:

方法详细资料

initBinder

public void initBinder(WebDataBinder dataBinder,
 RequestContext request)
                throws Throwable

Initialize a WebDataBinder with @InitBinder methods.

If the @InitBinder annotation specifies attributes names, it is invoked only if the names include the target object name.

覆盖:

initBinder 在类中 BindingContext

抛出:

Exception - if one of the invoked @InitBinder methods fails

Throwable - if @InitBinder method invocation fails

另请参阅:

• isBinderMethodApplicable(HandlerMethod, WebDataBinder)

isBinderMethodApplicable

protected boolean isBinderMethodApplicable(HandlerMethod initBinderMethod,
 WebDataBinder dataBinder)

Determine whether the given @InitBinder method should be used to initialize the given WebDataBinder instance. By default we check the specified attribute names in the annotation value, if any.

updateModel

public void updateModel(RequestContext request)
                 throws Throwable

从类复制的说明: BindingContext

Promote model attributes listed as @SessionAttributes to the session. Add BindingResult attributes where necessary.

覆盖:

updateModel 在类中 BindingContext

参数:

request - the current request

抛出:

Throwable - if creating BindingResult attributes fails

initModel

public void initModel(RequestContext request)
               throws Throwable

从类复制的说明: BindingContext

Populate the model in the following order:

1. Retrieve "known" session attributes listed as @SessionAttributes.
2. Invoke @ModelAttribute methods
3. Find @ModelAttribute method arguments also listed as @SessionAttributes and ensure they're present in the model raising an exception if necessary.

覆盖:

initModel 在类中 BindingContext

参数:

request - the current request

抛出:

Throwable - may arise from @ModelAttribute methods
