示例1: handle

private void handle(SpelNode node, Class<?> expressionRoot) throws ExpressionValidationException{
if (node instanceof MethodReference) {
verify((MethodReference) node, expressionRoot);
} else if (node instanceof Operator) {
Operator operator = (Operator) node;
handle(operator.getLeftOperand(), expressionRoot);
handle(operator.getRightOperand(), expressionRoot);
} else if (node != null) {
for(int i=0; i<node.getChildCount(); i++) {
SpelNode child = node.getChild(i);
if (child instanceof VariableReference ||
child instanceof TypeReference ||
child instanceof BeanReference) {
// stop inspecting if it's a variable or type reference.
// We can handle this later if we get smart about resolving these
break;
}
handle(child, expressionRoot);
}
