这是一个使用Seam2.2构建的应用程序,它在JBoss4.1.2下运行得很好。由于我的ISP的支持,我必须将JBoss升级到5.1版。我试着在JBoss 5下运行同样的应用程序,一切看起来都很好,但有一件事失败了。
它是一段代码,生成一些JSon来提供使用
Open Flash Chart libraries
JOFC libraries
为这些图表生成JSon。我们使用的方法基本上有一个seam工厂,它打印一个JSon,而我们在一个空白的.xhtml页面中引用这个工厂,图表从这里加载所需的JSon以正确呈现。以下是一些片段:
调用seam工厂的xhtml页面:
<f:view xmlns="http://www.w3.org/1999/xhtml"
xmlns:f="http://java.sun.com/jsf/core"
contentType="text/json; charset=UTF-8">
#{jsonGraficoPesoUsuario}
</f:view>
生成JSon字符串的工厂方法:
@Factory("jsonGraficoPesoUsuario")
public String graficoPesoUsuario()
{
...
String jsonString = chart.toString();
log.info("JSonString ==>> " + jsonString);
// try {
// jsonString = URLEncoder.encode(jsonString, "UTF-8");
// } catch (UnsupportedEncodingException e) {
// log.error("Erro ao tentar fazer o encode da string json ==>> " + e.getMessage());
// e.printStackTrace();
// }
return jsonString;
代码还显示,我们在发送之前尝试过对json字符串进行编码,但仍然没有成功。在将json打印到log.info的行中,json字符串得到了完美的保留,但是使用JBoss5会发生的情况是“(双引号)字符被html转义字符替换。
{"y_axis":{"min":100,"colour":"#96A9C5","grid-colour":"#DDDEE1","max":112},"title":{"text"
:"Gráfico de evolução de Peso"},"bg_colour":"#FFFFFF","is_decimal_separator_comma":1,"elements":[{"text":"Peso","values":[100.5,101.5,102.5,
102,103,107,109,110.5,108],"font-size":10,"type":"line","tip":"Linha do Peso"}],"num_decimals":2,"is_fixed_num_decimals_forced":1,"x_axis":{
"colour":"#96A9C5","grid-colour":"#DDDEE1","labels":{"rotate":"-24","labels":["01/05/10","15/05/10","25/05/10","01/06/10","09/06/10","25/06/
10","05/07/10","10/07/10","20/07/10"]}},"is_thousand_separator_disabled":0}
但是,与使用JBoss5相比,将打印以下字符串,请注意html编码替代了双引号:
{"y_axis":{"min":100,"colour":"#96A9C5","grid-colour":"#DDDEE1","max":112},"title":{"text":"Gráfico de evolução de Peso"},"bg_colour":"#FFFFFF","is_decimal_separator_comma":1,"elements":[{"text":"Peso","values":[100.5,101.5,102.5,102,103,107,109,110.5,108],"font-size":10,"type":"line","tip":"Linha do Peso"}],"num_decimals":2,"is_fixed_num_decimals_forced":1,"x_axis":{"colour":"#96A9C5","grid-colour":"#DDDEE1","labels":{"rotate":"-24","labels":["01/05/10","15/05/10","25/05/10","01/06/10","09/06/10","25/06/10","05/07/10","10/07/10","20/07/10"]}},"is_thousand_separator_disabled":0}
我已经检查了O.S语言环境,还对jboss http channel进行了配置,以将正文编码为server.xml:
<!-- A HTTP/1.1 Connector on port 8080 -->
<Connector protocol="HTTP/1.1" port="8080" address="${jboss.bind.address}"
connectionTimeout="20000" redirectPort="8443" useBodyEncodingForURI="true"/>
它不起作用。我们对应用程序中的所有资源和页面使用UTF-8。
