失踪propertyexception:无这样的属性:class:script1请求

Question

如何在servlet中在java中运行一个groovy脚本？使用以下代码，我有一个

失踪propertyexception：否这样的属性：class：script1

这是我的脚本

<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 request对象：

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