bindData
Purpose
Allows fine-grained control of binding request parameters from strings onto objects and the necessary types (data binding).
Examples
// binds request parameters to a target object
bindData(target, params)// exclude firstName and lastName
bindData(target, params, ['firstName', 'lastName'])// only use parameters starting with "author." e.g. author.email
bindData(target, params, "author")
bindData(target, params, ['firstName', 'lastName'], "author")// using inclusive map
bindData(target, params, [include: ['firstName', 'lastName']], "author")// using exclusive map
bindData(target, params, [exclude: ['firstName', 'lastName']], "author")
Description
Usage:
bindData(target, params, excludes, prefix)Arguments:
target - The target object to bind toparams - A Map of source parameters, often the params object when used in a controllerexcludes - The parameter names to excludeprefix - A string representing a prefix to use to filter parameters. A prefix separator of "." is assumed
The underlying implementation uses Spring's Data Binding framework. If the target is a domain class, type conversion errors are stored in the
errors property of the domain class.
