java 反射调用Service导致Spring注入Dao失效的解决方案

String serviceClass = templateInfo.getService();//service执行类的名称
String method = templateInfo.getMethod();//调用方法名
//根据反射执行保存操作
Class<?> classType = Class.forName(serviceClass);
Method m = classType.getDeclaredMethod(method,new Class[]{PageData.class});
m.invoke(classType.newInstance(),pd);

WebApplicationContext wac = ContextLoader.getCurrentWebApplicationContext(); 
DivStattisTabService service = (DivStattisTabService) 
Class<?>  cls = wac.getBean("divstattistabService").getClass(); 
Method m = classType.getDeclaredMethod(method,new Class[]{PageData.class});
m.invoke(wac.getBean("divstattistabService"),pd);
