在重定向请求从浏览器返回之前,不会调用Struts2拦截器(在视图呈现拦截器之后)

这是一个工作代码,类似于PreResultListener。

public String intercept(ActionInvocation invocation) throws Exception {
    invocation.addPreResultListener(new PreResultListener() {
        @Override
        public void beforeResult(ActionInvocation invocation, String resultCode) {
            try {

                // commit based on the resultCode comparision 
                if (StringUtils.equals(resultCode,"302_redirect")  {
                    TransactionService.commitTransaction();
                }
                // or commparision based on the redirect handler 
                // Class names are from struts-default.xml
                /*
                String resultConfigClassName = invocation.getProxy().getConfig().getResults().get(resultCode).getClassName();
                if (StringUtils.equals(resultConfigClassName,"org.apache.struts2.dispatcher.ServletRedirectResult")
                        || StringUtils.equals(resultConfigClassName, "org.apache.struts2.dispatcher.ServletActionRedirectResult")) {
                    TransactionService.commitTransaction();
                }
                */
            }
            catch (Exception e) {
                // Ignore don't do anything
            }
        }
    });

    TransactionService.startTransaction();
    invocation.invoke();
    TransactionService.commitTransaction();
}
