Question

I have a simple class something like:

public class ValueProvider {
     public void setExpression(String expression) {
         this.expression = expression;
     }


     public String getValue() {
         Expression exp = new SpelExpressionParser().parseExpression(this.expression);
         return exp.getValue(new StandardEvaluationContext(new Foo()), String.class);
     }
     private String expression;
}

Unfortunately, when I try to register the provider it tries to evaluate the provided expression:

<bean class="com.ValueProvider">
    <property name="expression" value="#{bar}" />
</bean>

Any ideas for how to get Spring to treat the value attribute as a string/expression literal?

according to the state of SPR-704 this is not possible.
