org.springframework.security.oauth2.provider.expression

Class OAuth2ExpressionParser

java.lang.Object

org.springframework.security.oauth2.provider.expression.OAuth2ExpressionParser

All Implemented Interfaces:

org.springframework.expression.ExpressionParser

public class OAuth2ExpressionParser
extends Object
implements org.springframework.expression.ExpressionParser

A custom ExpressionParser that automatically wraps SpEL expression with OAuth2SecurityExpressionMethods.throwOnError(boolean). This makes it simple for users to specify an expression and then have it verified (providing errors) after the result of the expression is known.

Note: The implication is that all expressions that are parsed must return a boolean result. This expectation is already true since Spring Security expects the result to be a boolean.
