问题 My app uses http://prevayler.org/ for persistence, piggybacking Java Object serialization. After upgrade to Android 7.0 (Nougat) users cannot open their data, since the deserialization does not work any more: java.io.StreamCorruptedException: invalid type code: 71 at java.io.ObjectInputStream.readString(ObjectInputStream.java:1647) at java.io.ObjectInputStream.readEnum(ObjectInputStream.java:1737) ... at java.io.ObjectInputStream.readObject(ObjectInputStream.java:373) at org.prevayler

Deserialize Xml with empty elements

由 你。 提交于 2019-12-19 03:14:04
问题 Consider the following XML: <a> <b>2</b> <c></c> </a> I need to deserialize this xml to an object. So, i wrote the following class. public class A { [XmlElement("b", Namespace = "")] public int? B { get; set; } [XmlElement("c", Namespace = "")] public int? C { get; set; } } Since i'm using nullables, i was expecting that, when deserialing the above xml, i would get an object A with a null C property. Instead of this, i get an exception telling the document has an error. 回答1: There's a

deserialize json field into plain string with gson

问题 I am trying to deserialize a json object into a java bean. The main issue I am facing is that I'd like to treat the field object of the json string as a plain string, even if it contains a potentially correct json object. The json structure is like this: { "type":"user", "object":{ "id":"1", ...} } How can i tell gson to ignore the object value so that it doesn't get deserialized into an object? I'd like it only to be mapped to a plain String field in my bean so that I can dispose a proper

Here's my class (simplified): [DataContract] public class Component { public Component() { // I'm doing some magic here. } } How can I deserialize that class without invoking a constructor using JsonConvert.DeserializeObject ? Sorry if not clear, feel free to ask questions. 回答1: You could create a class that inherits from CustomCreationConverter and use FormatterServices.GetSafeUninitializedObject to create your object. It skips calling the

Hashmap slower after deserialization - Why?

由 a 夏天 提交于 2019-12-18 13:41:12
问题 I have a pretty large Hashmap (~250MB). Creating it takes about 50-55 seconds, so I decided to serialize it and save it to a file. Reading from the file takes about 16-17 seconds now. The only problem is that lookups seems to be slower this way. I always thought that the hashmap is read from the file into the memory, so the performance should be the same compared to the case when I create the hashmap myself, right? Here is the code I am using to read the hashmap into a file: File file = new
