小编Vov*_*van的帖子

我想将GET参数从URL传递给方法,通过单击按钮调用该方法.例如,我有URL:/someurl/semepage.xhtml?id=1.我的页面上有一个按钮:

<p:commandButton value="say it" action="#{test.sayIt(param['id'])}"/>

豆看起来像:

@ManagedBean
@ViewScoped
public class Test{
    public void sayIt(String value){
        System.out.println(value);
    }
}

但是,当我点击按钮时,它只是没有反应.为什么会这样？方法甚至没有调用.

如果我像这里传递参数staticaly:

<p:commandButton value="say it" action="#{test.sayIt('someword')}"/> 

一切都好.

我已经使用了hibernate 4,一切正常.现在我想将Hibernate更新到应用程序中的最新版本.

应用程序构建成功,但在glassfish使用stacktrace 部署到服务器时失败:

我怎样才能解决这个问题 ？我没有使用任何jboss日志记录.

我的 IDE（想法）说：此处不允许使用元素“属性”。

还有一些其他元素也是不允许的。但项目建设成功。我怎样才能解决这个问题？

我是Docker的新手,我在使用gradle-docker-plugin从gradle脚本构建映像时遇到问题:

task dockerBuildImage(type: DockerBuildImage, dependsOn: [dockerCreateDockerfile, assemble]) {
    tag = "my_tag_here"
    dockerFile = dockerCreateDockerfile.destFile
    inputDir = dockerCreateDockerfile.destFile.parentFile
}

而且我得到这样的堆栈跟踪:

Building image using context 'D:\Learning\1\myproject\webapp\build'.
Using Dockerfile 'D:\Learning\1\myproject\webapp\build\Dockerfile'
Using tag 'localhost:5000/test/myproject-webapp:1.0.0-20170318135307' for image.
