如何编码和解码字符串以便在查询字符串中使用？

Question

如何在jsf中表示查询字符串？

我有一个类似于下面的查询字符串。

  

... /面/ WPages /导航/ Catalog.xhtml STOREID = 1＆安培; CATEGORYID = 1005＆安培; drilldownproperty1 = drilldownpropertyval1＆安培; drilldownproperty2 = drilldownpropertyval2＆安培; drilldownproperty3 = drilldownpropertyval3＆安培; ...

我想代表参数

drilldownproperty1=drilldownpropertyval1&drilldownproperty2=drilldownpropertyval2&drilldownproperty3=drilldownpropertyval3 ...

有类似的东西：

drilldownproperty=drilldownpropertyvals

其中drilldownpropertyvals代表drilldownproperty1=drilldownpropertyval1&drilldownproperty2=drilldownpropertyval2&drilldownproperty3=drilldownpropertyval3

如何在我的managebean上执行url重定向之前和之后对字符串进行编码和解码？

Answer 1

java.net.URLEncoder和java.net.URLDecoder for。

String url = "some.xhtml?drilldownproperty=" + URLEncoder.encode(drilldownpropertyvals, "UTF-8");

然后在另一边

String drilldownpropertyvals = URLDecoder.decode(drilldownproperty, "UTF-8");
