hibernate 5.1 spatial的文档尚未发布(AFAIK),我试图将具有JST几何字段的实体持久化到PostgreSQL 9.5 + Postgis 2.2,没有任何运气.
我还注意到hibernate-core-5.1.0中没有org.hibernate.spatial包.我尝试过以下注释的变体:
@javax.persistence.Column(name = "the_geom", columnDefinition = "Geometry")
public com.vividsolutions.jts.geom.Geometry geom;

当columnDefinition设置为"Point"时,我得到"column",the_geom"的类型为point,但表达式的类型为bytea".在hibernate spatial 4文档中,据说版本5+不需要@Type注释,但应该使用什么呢?如何将geom存储为有效的Postgis几何?
我正在努力将Primefaces bean属性直接发送到javascript,以便打开一个新页面并将bean属性的内容写入新页面.
我正在使用Primefaces 4.0.
我有一个这样的命令按钮:
<p:commandButton id="buttonId" update="buttonId, otherComponentId"
value="press me" process="@this" actionListener="#{homeController.myMethod}"
oncomplete="handleComplete(xhr, status, args)">
</p:commandButton>

在handleComplete中,javascript函数args未定义,但不是xhr和status.javascript函数定义:
function handleComplete(xhr, status, args){
var w = window.open();
w.document.open();
alert(xhr.responseText.substring(100));
alert(status);
alert(args);
var d = '<head></head><body>'+ args.firstParam +'<body>';
w.document.write(d);
w.document.close();
}

首先警告它给我页面,第二个解析错误,错误是:Uncaught TypeError:无法读取未定义的属性'firstParam'
我想在args中传入一个这样的字符串:
public String MyMethod() {
RequestContext context = RequestContext.getCurrentInstance();
context.addCallbackParam("firstParam", "my string");
return "";
}

并使用javascript访问它args.firstParam.
该方法被调用,(我有一些工作的打印屏幕.)
我必须尝试这种方式,而不是将文本设置为
<h:outputText id="myText" escape="false" rendered="true"
value="#{homeController.property}" />

然后得到这个元素的innerHTML,因为我将使用innerHTML获得的内容与bean中的字符串变量不同.这种方法有效但不是我想要的.我想知道为什么args对象是未定义的,或者我怎样才能从javascript中管理bean属性.谢谢.
我正在尝试将来自AngularJS 1.3应用程序的跨源请求发送到REST服务.虽然我启用了CORS过滤器,但我收到了403 Forbidden响应.这是请求(从chrome dev工具复制粘贴).在IE 9上它似乎工作.我在Chrome和Firefox上收到403错误代码.
