Question

使用了groovy和java 我有用于吐痰的groovy脚本，

 def msgO = app.getConversation()
    msgO+=msg.getText()        
    def list = msgO.split("\\+")

何时收到错误使用java代码运行：

CaptureUtil captureUtil = new CaptureUtil();
            binding.setVariable("cap", captureUtil);    
            GroovyShell shell = new GroovyShell(binding);    
            boolean status = (boolean) shell.evaluate(template);

得到错误：

运行groovy脚本时运行良好，仅在运行java时出错。

您可以尝试使用

msgO.split(Pattern.quote('+'))

当groovy运行java时获取错误
