如果实现了CookiesAware了，还需要引用org.apache.struts2.interceptor.CookieInterceptor过滤器，否则拿不到值
同时还要能看到这样的错误No object in the CompoundRoot has a publicly accessible property named 'JSESSIONID'
解决办法是

2 增加一个setJSESSIONID(String value)的空方法
spring自动加载
想按名称加载

需要写成struts.objectFactory.spring.autoWire = name
private calculatorService cs;
public void setCs1(calculatorService cs){
