Examples of org.springframework.binding.expression.ExpressionParser.parseExpression()

org.springframework.binding.expression.ExpressionParser.parseExpression()
Parse the expression string and return a compiled Expression object you can use for evaluation. Some examples:
```
 3 + 4 name.firstName 
```
@param expressionString the raw expression string to parse @param context a context for influencing this expression parsing routine (optional) @return an evaluator for the parsed expression @throws ParserException an exception occurred during parsing

    if (StringUtils.hasText(output.getValue())) {
      value = output.getValue();
    } else {
      value = name;
    }
    Expression source = parser.parseExpression(value, new FluentParserContext().evaluate(RequestContext.class));
    Expression target = parser.parseExpression(name, new FluentParserContext().evaluate(MutableAttributeMap.class));
    DefaultMapping mapping = new DefaultMapping(source, target);
    parseAndSetMappingConversionExecutor(output, mapping);
    parseAndSetMappingRequired(output, mapping);
    return mapping;
