我想要一个非常简单的事情。只需创建我自己的转换器并提供一些属性。我知道<f:attribute>但它变得很难看，所以我想要真正的属性......我也想在Eclipse中自动完成工作等。
我从一个taglib开始，将我的转换器添加到那里，就像他们在Omnifaces中做的那样，用@FacesConverter创建我的转换器
但是我得到以下例外：

实现TagHandler感觉错误并且无论如何都不起作用，因为未调用Converter。我在facelets.LIBRARIES中使用web.xml注册了我的taglib，我的taglib非常简单：
<?xml version="1.0" encoding="UTF-8"?>
<facelet-taglib xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-facelettaglibrary_2_0.xsd" version="2.0">
<namespace>http://mynamespace/</namespace>
<tag>
<tag-name>org.bogus.myConverter</tag-name>
<converter>
<converter-id>org.bogus.myConverter</converter-id>
<handler-class>org.bogus.MyConverter</handler-class>
</converter>
<attribute>
<name>asd</name>
<name>bb</name>
<name>cc</name>
</attribute>
</tag>
</facelet-taglib>
编辑：
为了让o:converter像提议的那样工作，需要在omnifaces中进行此源代码更改。显然我无法在我的项目中保留这种解决方法：/但是转换器可以用myfaces或deltaspike包裹，例如在myfaces source中查看ConverterWrapper：
RenderTimeTagHandlerHelper.java
try {
Class clazz = null;
T wrappedInstance = null;
for (PropertyDescriptor property : Introspector.getBeanInfo(instance.getClass()).getPropertyDescriptors()) {
if (property.getName().equals("wrapped")) {
wrappedInstance = (T) property.getReadMethod().invoke(instance);
clazz = wrappedInstance.getClass();
}
}
if (clazz == null) {
clazz = instance.getClass();
}
else {
instance = wrappedInstance;
}
for (PropertyDescriptor property : Introspector.getBeanInfo(clazz).getPropertyDescriptors()) {
Method setter = property.getWriteMethod();
