我已经安装了wildfly 8.1,因为我已经配置了一个使用EclipseLink的项目,我试图配置wildfly来使用它.

但是,我总是一样的错误:

我虽然遵循了官方文档的说明,但没有改变!我已将eclipseLink的jar添加到"modules\system\layers\base\org\eclipse\persistence\main"和module.xml:

<module xmlns="urn:jboss:module:1.3" name="org.eclipse.persistence">
    <resources>
        <resource-root path="jipijapa-eclipselink-1.0.1.Final.jar"/>
        <resource-root path="eclipselink.jar"/>
    </resources>

    <dependencies>
        <module name="asm.asm"/>
        <module name="javax.api"/>
        <module name="javax.annotation.api"/>
        <module name="javax.enterprise.api"/>
        <module name="javax.persistence.api"/>
        <module name="javax.transaction.api"/>
        <module name="javax.validation.api"/>
        <module name="javax.xml.bind.api"/>
        <module name="org.antlr"/>
        <module name="org.apache.commons.collections"/> …

我使用带有EclipseLink的wildfly,我想跟踪SQL语句.我根据文档配置了EclipseLink ,除SQL日志外,所有工作都正常.我在persistence.xml中添加了这些属性:

    <properties>
        <property name="eclipselink.logging.level.sql" value="FINE" />
        <property name="eclipselink.logging.parameters" value="true" />
        <property name="eclipselink.debug" value="OFF" />
        <property name="eclipselink.weaving" value="static" />
        <property name="eclipselink.logging.logger" value="DefaultLogger" />
    </properties>

但没有SQL日志.我究竟做错了什么？

我尝试将 JDBC 日志激活到 Wildfly：

我在子系统“urn:jboss:domain:logging:2.0”中添加了我的standalone.xml：

<logger category="jboss.jdbc.spy">
    <level name="TRACE"/>
</logger>

并在我的数据源语句中： spy="true"

但是，我没有 SQL 日志！我忘记了什么吗？有任何想法吗 ？

编辑：显然，问题出在 arquillian 上，因为当我启动服务器时它似乎可以工作，但当服务器由 arquillian 启动时就不行了。有任何想法吗 ？

我想在推送操作上刷新属性的值,但我不知道如何从函数访问属性!

export class Datas {
    prop1 = "my val";
}

var connection = new WebSocket('ws://localhost:8787', 'json');
connection.onmessage = function (e) {
     // prop1 of Datas = e.data;
};

有任何想法吗 ？

编辑:页面加载后,我想在接收推送消息时刷新数据.

编辑2:测试代码

data.js:

export class Data {
    static information = '';
}

viewModel.js

import {bindable} from 'aurelia-framework';
import { Data } from 'data';

export class ViewModel {
    constructor() { 
        this.informaton = Data.information;
    }

    logState(){
        console.log("state of Data.information : " + Data.information);
        console.log("state of this.information : " + this.information);
    } …

我想知道是否可以将重复的父索引传递给重复的转换器？
我试过这个:

<div repeat.for="row of router.navigation | myFilter:1:$parent.$index">

但它不起作用!
有什么想法吗？任何解决方法？
