gwtp-sample-basic-spring 示例中的 RPC Cookie 错误

Question

我克隆了this example

当运行它时，我得到以下错误

An error occured: Cookie provided by RPC doesn't match request cookie, aborting action, possible XSRF attack. (Maybe you forgot to set the security cookie?) While executing action: com.gwtplatform.samples.basicspring.shared.dispatch.SendTextToServerAction

如何解决这个问题？

Answer 1

经过 3 天的谷歌搜索，我终于找到了解决方案。

覆盖 SendTextToServerAction 类中的 unSecured 方法：

public class SendTextToServerAction extends ActionImpl<SendTextToServerResult> {
    private String textToServer;

    public SendTextToServerAction(final String textToServer) {
        this.textToServer = textToServer;
    }
    /**
     * For serialization only.
     */
    @SuppressWarnings("unused")
    private SendTextToServerAction() {
    }

    public String getTextToServer() {
        return textToServer;
    }

    @Override
    public boolean isSecured() {
        return false;
    }
