How to serialize a Map<String, String> using Simple XML?

阅读更多关于 How to serialize a Map using Simple XML?

问题 How would you go about serialising a Map using simple XML so that it looks something like: <elem foo="value">key</elem> Instead of the normal <elem foo="key">value</elem> (The map is one to many, and since this will be edited by humans, I wanted it to be clearer.) [EDIT]: Doesn't Fix. 回答1: Have you tried something like: @ElementMap(entry="property", value="value", attribute=true, inline=true) private Map<String, String> map; or some combination, i.e. to use the other attributes of the

I don't know ho to deal with embedded collection. I know about @ElementList annotation but don't know how to use

How to ignore unused XML elements while deserializing a document?

阅读更多关于 How to ignore unused XML elements while deserializing a document?

I'm using SimpleXml to (de)serialize POJOs. Now, I have a big XML which has some elements which are not needed. For instance, with this XML: <Root> <Element>Used</Element> <Another>Not used</Another> <Root> I want to create a POJO which looks like: @Root class Root{ @Element private String element; } Problem is that I'm getting this Exception: simpleframework.xml.core.ElementException: Element 'Another' does not have a match in class blah.blah.Blah at line 1 So... how should I configure the POJO so that I can parse the XML correctly? Set strict to false within the Root annotation to ignore any

How to solve the XML parsing performance issue on Android

阅读更多关于 How to solve the XML parsing performance issue on Android

I have to read a XML file with about ~4000 lines on Android. First I tried the SimpleXML library because it's the easiest and it took about 2 minutes on my HTC Desire. So I thought maybe SimpleXML is so slow because of reflection and all the other magic that this library uses. I rewrote my parser and used the built-in DOM parsing method with some special attention for performance. That helped a bit but it still took about 60 seconds which is still totally unacceptable. After a bit of research I found this article on developer.com . There are some graphs that show that the other two available

Is it possible to apply a single annotation to multiple use-site targets in Kotlin?

阅读更多关于 Is it possible to apply a single annotation to multiple use-site targets in Kotlin?

According to the documentation: https://kotlinlang.org/docs/reference/annotations.html You can apply multiple annotations to a single site-use target, but is there a way to apply the same annotation to multiple site-use targets? My use-case is decorating classes with annotations for SimpleXML. To use an immutable data class , you have to annotate both the field and the constructor parameter: data class Data( @field:Element(name = "ID") @param:Element(name = "ID") val id: Int, @param:Element(name = "TEXT") @field:Element(name = "TEXT") val text: String) For data classes with many fields, you
