如何从servlet中运行java中的groovy脚本？使用下面的代码，我有一个

  

MissingPropertyException：没有这样的属性：请求类：Script1

这是我的剧本

<script type="server/groovy">
        import com.daimler.Car
        def id = request.getParameter("id")
        car = Car.lookup(id)
    </script>

这是我的Java代码

public void runScript(HttpServletRequest request) {

Script script = groovyShell.parse("def id = request.getParameter(\"id\")\n" +
"        car = Car.lookup(id)");

        Map bindings = script.getBinding().getVariables();

        bindings.put("id",1);
        Object ret = script.run(); //a+b+3

        //and if you changed variables in script you can get their values 
        Object aAfter = bindings.get("car"); 

}

您还需要在绑定中传递HttpServletRequest请求对象：

Map bindings = script.getBinding().getVariables(); bindings.put("id",1); bindings.put("request", request); Object ret = script.run(); //a+b+3 (...)
