I would like to send messages in the form of JSON objects to a server and parse the JSON response from the server.
Example of JSON object
{
"post": {
"username": "John Doe",
"message": "test message",
"image": "image url",
"time": "current time"
}
}
我试图通过逐个属性手动解析JSON.是否有任何库/实用程序可用于简化此过程？
我很惊讶这些都没有被提及:而是使用json来代替简单的手工处理.org的小软件包GSon和Jackson使用起来更方便.所以:
So you can actually bind to your own POJOs, not some half-assed tree nodes or Lists and Maps. (and at least Jackson allows binding to such things too (perhaps GSON as well, not sure), JsonNode, Map, List, if you really want these instead of 'real' objects)
EDIT 19-MAR-2014:
Another new contender is Jackson jr library: it uses same fast Streaming parser/generator as Jackson (jackson-core), but data-binding part is tiny (50kB). Functionality is more limited (no annotations, just regular Java Beans), but performance-wise should be fast, and initialization (first-call) overhead very low as well.
So it just might be good choice, especially for smaller apps.
