Question

阅读以下问题（How set charset in a primefaces webapp?），我试图将一些特殊字符作为参数传递给managedBean（例如：''''''''''''''''''''''''''''''问题的答案不起作用：

JBWEB000065: HTTP Status 500 - /utf8/utf8_test.xhtml @23,153 value="#{testBean.testEncoding(''´áéíóúÁÉÍÓÚ&')}" EL Expression Unbalanced: ... #{testBean.testEncoding(''´áéíóúÁÉÍÓÚ&')}

到目前为止，问题似乎是“'”（'）字符，因为某些方法在将其发送到托管bean之前会对其进行转换，

调用托管bean的代码是：

<h:outputText value="#{testBean.pruebaEncoding('&#39;&#180;&#225;&#233;&#237;&#243;&#250;&#193;&#201;&#205;&#211;&#218;&amp;')}" />

和托管bean：

public String pruebaEncoding(String strencoded) {

    FileWriter writer;
    try {
        writer = new FileWriter("/desarrollo/workspaces/workspace-eclipse-mars-test/project/filter.test");

        writer.write(strencoded);

        writer.close();
    } catch (IOException e) {
        e.printStackTrace();
    }

    return strencoded;
}

感谢您的帮助

提示：重要的是应用程序可以将结果写入文件，因为另一个ant脚本使用它来做一些事情（）
