Beetl 模板引擎 3.18，集成 javax.script.ScriptEngineManager

干不动了伙计们，老板说每天导它个 5000 App 下载

本次发版新增了javax.script 集成

 ScriptEngineManager scriptEngineManager = new ScriptEngineManager(); ScriptEngine beetlEngine = scriptEngineManager.getEngineByName("beetl"); //一个简单例子 SimpleBindings simpleBindings = new SimpleBindings(); simpleBindings.put("arg",arg); Map map = null; try {   map = (Map)beetlEngine.eval("return arg.age+(arg.pay+12);",simpleBindings);   return map.get("return"); } catch (ScriptException e) {   System.out.println(e); }

其他调整

• 修复Native调用，空指针提示不友好的问题
• 取消内部一个性能优化类VarRefOptimal，因为它和VarRef 在出错提示上表现的不一致，性能提升有限
