struts2 token实现方式
1
??? struts2 的token标签 会在页面产生
?
public static final String DEFAULT_TOKEN_NAME = "struts.token"; public static final String TOKEN_NAME_FIELD = "struts.token.name"; public static String setToken(String tokenName) { Map session = ActionContext.getContext().getSession(); String token = generateGUID(); try { session.put(tokenName, token); } catch(IllegalStateException e) { // WW-1182 explain to user what the problem is String msg = "Error creating HttpSession due response is commited to client. You can use the CreateSessionInterceptor or create the HttpSession from your action before the result is rendered to the client: " + e.getMessage(); LOG.error(msg, e); throw new IllegalArgumentException(msg); } return token; }?这样就只能这里的tokenName竟然是一个变量量，这样的话，就解决了不同页面的key不一样，对一个页面进行表单重复提交 进行验证，如果出现两个页面 同时添加的时候，就不能都是 默认，不然会使另外一个页面失去有效
