I had the same problem, the solution found out to be rather simple though. Just choose one of the libraries - either gson-1.6-sources or gson-1.6 to be added to your path and bravely delete another one from there.
It caused me quite lot of trouble, not only with error, you've mentioned but also with NoClassDefFoundError for Gson class within my Activity code.
P.S. I would appreciate any clarification, why this duplication error actually happens:).
在string.xml中尝试这个：
{\"status\":\"success\",\"data\":{\"name\":\"Test\",\"mob_no\":\"8089647076\",\"country_prefix\":\"+91\",\"email\":\"\"}}
Try this in your string.xml:
{\"statu ...
我遇到了同样的问题，但解决方案却相当简单。 只需选择其中一个库 - gson-1.6-sources或gson-1.6即可添加到您的路径中，并从那里勇敢地删除另一个库。 它给我带来了很多麻烦，不仅有错误，你已经提到过，而且我的Activity代码中的Gson类也有NoClassDefFoundError。 PS我会感激任何澄清，为什么这个重复错误实际发生:)。 I had the same problem, the solution found out to be rather simple though. ...
Gson是一个主流图书馆。 您的问题似乎与您的服务器设置有关：您在类路径中使用Gson库编译您的servlet（当您运行程序时，它也可以在类路径中，可能来自IDE）。 但是当你把你的战争放到服务器上（Gson错过了）时， doPost会遇到new Gson() 。 因此，在编译时和运行时都要确保在类路径中有Gson库jar 。 Gson is a mainstream library. It seems that your issue is related to your server setup: you ...
你在groupId中犯了一个错误，它是“com.google。code .gson”： "com.google.code.gson" % "gson" % "2.2"
You made a mistake in the groupId, it is "com.google.code.gson": "com.google.code.gson" % "gson" % "2.2"
向类添加一个空构造函数，因为这只会用于设置值，如果上下文未初始化，这不会导致任何问题 public UserValues() {
}
add an empty constructor to the class as this will only be used to set values this should not cause any issues if the context is not initialised public UserValues() {
}
我相信你把javac和java参数顺序混淆了。 语法是： javac
和 java [-options] class [args...]
所以它应该是这样的 javac -cp gson.jar myProgram.java
java命令也是如此。 I believe you have the javac and java argument order mixed up. The syntax is: javac
您可以使用数组 String[] array = gson.fromJson(jsonString, String[].class);
或使用TypeToken Type listType = new TypeToken>() {}.getType();
List list = gson.fromJson(jsonString, listType);
You can use an array String[] array = gson.fromJso ...
