@Component public class AviatorAddFunction {

private static final LOGGER LOGGER =LoggerFactory.getLogger(AviatorAddFunction.class);

private final List<AbstractFunction> functionList;

@Autowired
public AviatorAddFunction(List<AbstractFunction> functionList) {
    this.functionList = functionList;
}

public void init() {
    this.functionList.forEach(abstractFunction -> {
        LOGGER.info("AviatorAddFunction add: {}", abstractFunction.getName());
        AviatorEvaluator.addFunction(abstractFunction);
    });
}

}

程序执行时，出现如下异常： com.googlecode.aviator.exception.FunctionNotFoundException: Function not found: path

Please ensure that the path function exists and add it to the AviatorEvaluator before compiling or executing the expression.
