OK, I deleted my previous answer because it turned out to be exactly what you didn't want.

I don't know how well it works with GWT, but we use the <a href="http://json-lib.sourceforge.net/" rel="nofollow noreferrer">json-lib</a> library to serialize objects in a normal Java project where I work.

It can <a href="http://json-lib.sourceforge.net/snippets.html#Creating_a_JSONObject_from_a_JavaBean" rel="nofollow noreferrer">create a JSONObject directly from a JavaBean</a>, then use the resulting JSONObject's toString() method to get the actual JSON string back.

Not sure if <a href="http://jackson.codehaus.org/Tutorial" rel="nofollow noreferrer">Jackson</a> would work for you.
I don't know if there's GWT-specific you are looking for; if not it should work.

But its serialization/deserialization works quite well, like:

<pre><code>// read json, create object
ObjectMapper mapper = new ObjectMapper();
MyBean bean = mapper.readValue(jsonAsString, MyBean.class);

// and write out
StringWriter sw = new StringWriter();
mapper.writeValue(sw, user);
String jsonOut = sw.toString();
</code></pre>

You do need accessors (<code>getX()</code> to serialize, <code>setX()</code> to deserialize; can annotate methods with other names), but that's about it.

It seems that I found the right answer to my question

I figured out that bean to json and json to bean conversion in GWT isn't a trivial task. Known libraries would not work because GWT would require their full source code and this source code must use only Java classes that are amoung emulated by GWT. Also, you cannot use reflection in GWT. Very tough requirements!

I found the only existing solution named <a href="http://code.google.com/p/gwt-jsonizer/" rel="noreferrer">gwt-jsonizer</a>. It uses a custom <a href="http://google-web-toolkit.googlecode.com/svn/javadoc/1.5/com/google/gwt/core/ext/Generator.html" rel="noreferrer">Generator</a> class and requires a satellite interface for each "jsonable" bean. Unfortunately, it does not work without patching on the latest version of GWT and has not been updated for a long time.

So, I personally decided that it is cheaper and faster to make my beans khow how to convert themselves to and from json. Like this:

<pre><code>public class SmartBean {
 private String name;

 public String getName() { return name; }
 public void setName(String value) { name = value; }

 public JSONObject toJson() {
 JSONObject result = new JSONObject();
 result.put("name", new JSONString(this.name));
 return result;
 }
 public void fromJson(JSONObject value) {
 this.name = value.get("name").isString().stringValue();
 }

}
</code></pre>

<code>JSONxxxx</code> are GWT built-in classes that provide low-level json support.

blocks|key|1842228|text|看看GWT的Overlay+Types。我认为这是迄今为止在GWT中使用JSON的最简单方法。以下是链接文章中修改后的代码示例：|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1842229|public+class+Customer+extends+JavaScriptObject+{
++++public+final+native+String+getFirstName()+/*-{+

++++public+final+native+void+setLastName(String+value)+/*-{
++++++++this.last_name+=+value;
++++}-*/;
}|code-block|syntax|javascript|1842230|一旦定义了overlay类型，就很容易从JSON创建一个JavaScript对象并在Java语言中访问它的属性：|1842231|public+static+final+native+Customer+buildCustomer(String+json)+/*-{

}-*/;|1842232|如果您再次需要对象的JSON表示，您可以将overlay类型包装在JSONObject中：|1842233|Customer+customer+=+buildCustomer("{'Bart',+'Simpson'}");
customer.setFirstName("Lisa");
//+Displays+{"first_name":"Lisa","last_name":"Simpson"}
Window.alert(new+JSONObject(customer).toString());|1842234|entityMap|0|LINK|mutability|MUTABLE|url|http://code.google.com/p/google-web-toolkit/wiki/OverlayTypes^0|6|D|0|0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|Y|8|@]|9|@$A|Z|B|10|1|11]]|C|$]]|$1|D|3|E|5|F|7|12|8|@]|9|@]|C|$G|H]]|$1|I|3|J|5|6|7|13|8|@]|9|@]|C|$]]|$1|K|3|L|5|F|7|14|8|@]|9|@]|C|$G|H]]|$1|M|3|N|5|6|7|15|8|@]|9|@]|C|$]]|$1|O|3|P|5|F|7|16|8|@]|9|@]|C|$G|H]]|$1|Q|3|-4|5|6|7|17|8|@]|9|@]|C|$]]]|R|$S|$5|T|U|V|C|$W|X]]]]

Take a look at GWT's <a href="http://code.google.com/p/google-web-toolkit/wiki/OverlayTypes" rel="noreferrer">Overlay Types</a>. I think this is by far the easiest way to work with JSON in GWT. Here's a modified code example from the linked article:

<pre><code>public class Customer extends JavaScriptObject {
 public final native String getFirstName() /*-{ 
 return this.first_name;
 }-*/;
 public final native void setFirstName(String value) /*-{
 this.first_name = value;
 }-*/;
 public final native String getLastName() /*-{
 return this.last_name;
 }-*/;
 public final native void setLastName(String value) /*-{
 this.last_name = value;
 }-*/;
}
</code></pre>

Once you have the overlay type defined, it's easy to create a JavaScript object from JSON and access its properties in Java:

<pre><code>public static final native Customer buildCustomer(String json) /*-{
 return eval('(' + json + ')');
}-*/;
</code></pre>

If you want the JSON representation of the object again, you can wrap the overlay type in a JSONObject:

<pre><code>Customer customer = buildCustomer("{'Bart', 'Simpson'}");
customer.setFirstName("Lisa");
// Displays {"first_name":"Lisa","last_name":"Simpson"}
Window.alert(new JSONObject(customer).toString());
</code></pre>

The simplest way would be to use GWT's built-in JSON API. Here's <a href="http://google-web-toolkit.googlecode.com/svn/javadoc/2.0/com/google/gwt/json/client/" rel="noreferrer">the documentation</a>. And here is a <a href="http://gwttutorials.com/2009/07/27/parsing-json-with-gwt/" rel="noreferrer">great tutorial</a> on how to use it.

It's as simple as this:

<pre><code>String json = //json string
JSONValue value = JSONParser.parse(json);
</code></pre>

The JSONValue API is pretty cool. It lets you chain validations as you extract values from the JSON object so that exceptions will be thrown if anything's amiss with the format.

Try this serializer from Google Code: <a href="http://code.google.com/p/json-io/" rel="nofollow">http://code.google.com/p/json-io/</a>

If you need to write or read JSON format in Java, this is the tool to use. No need to create extra classes, etc. Convert a Java object graph to JSON format in one call. Do the opposite - create a JSON String or Stream to Java objects. This is the fastest library I have seen yet to do this. It is faster than ObjectOutputStream and ObjectInputStream in most cases, which use binary format. 

Very handy utility.

Another thing to try is the new <a href="http://code.google.com/p/google-web-toolkit/wiki/AutoBean" rel="noreferrer">AutoBean</a> framework introduced with GWT 2.1. 

You define interfaces for your beans and a factory that vends them, and GWT generates implementations for you. 

<pre><code>interface MyBean {
 String getFoo();
 void setFoo(String foo);
}

interface MyBiggerBean {
 List&lt;MyBean&gt; getBeans();
 void setBeans(List&lt;MyBean&gt; beans&gt;;
}

interface Beanery extends AutoBeanFactory{
 AutoBean&lt;MyBean&gt; makeBean();
 AutoBean&lt;MyBiggerBean&gt; makeBigBean();
}

Beanery beanFactory = GWT.create(Beanery.class);

void go() {
 MyBean bean = beanFactory.makeBean().as();
 bean.setFoo("Hello, beans");
}
</code></pre>

The <a href="http://code.google.com/p/google-web-toolkit/wiki/AutoBean#AutoBeanCodex" rel="noreferrer">AutoBeanCodex</a> can be used to serialize them to and from json. 

<pre><code>AutoBean&lt;MyBean&gt; autoBean = AutoBeanUtils.getAutoBean(bean);
String asJson = AutoBeanCodex.encode(autoBean).getPayload();

AutoBean&lt;MyBean&gt; autoBeanCloneAB = 
 AutoBeanCodex.decode(beanFactory, MyBean.class, asJson );

MyBean autoBeanClone = autoBeanCloneAB.as(); 
assertTrue(AutoBeanUtils.deepEquals(autoBean, autoBeanClone));
</code></pre>

They work on the server side too — use <code>AutoBeanFactoryMagic.create(Beanery.class)</code> instead of <code>GWT.create(Beanery.class)</code>.

<a href="http://restygwt.fusesource.org/index.html">RestyGWT</a> is a powerful library for encoding or decoding Java Object to JSON in GWT:

<pre><code>import javax.ws.rs.POST;
...
public interface PizzaOrderCodec extends JsonEncoderDecoder&lt;PizzaOrder&gt; {
}
</code></pre>

Then:

<pre><code>// GWT will implement the interface for you
PizzaOrderCodec codec = GWT.create(PizzaOrderCodec.class);

// Encoding an object to json
PizzaOrder order = ... 
JSONValue json = codec.encode(order);

// decoding an object to from json
PizzaOrder other = codec.decode(json);
</code></pre>

It has also got several easy to use API for consuming Restful web services.

Have a nice time.

I am looking for a simple Json (de)serializer for Java that might work with GWT. I have googled a bit and found some solutions that either require annotate every member or define useless interfaces. Quite a boring. Why don't we have something really simple like

<pre><code>class MyBean {
 ...
}

new GoodSerializer().makeString(new MyBean());
new GoodSerializer().makeObject("{ ... }", MyBean.class)
</code></pre>

我正在寻找一个简单的Json (反) Java序列化程序，可能与GWT一起工作。我用谷歌搜索了一下，找到了一些解决方案，它们要么需要注释每个成员，要么需要定义无用的接口。挺无聊的。为什么我们不做一些非常简单的事情，比如class MyBean {    ...}new GoodSerializer().makeStri...
