我在Play中編寫小型高音揚聲器應用程序!用簡單的REST API使用RESTEasy。我有一個簡單的資源:RESTEasy json JAXB反編組問題
@GET
@Path("/tweets/all")
@Produces("application/xml")
public TweetList all(@QueryParam("page") @DefaultValue("1") Integer page) {
//return Tweet.find("order by dateCreated desc").fetch(page, 100);
List<Tweet> l = Tweet.find("order by dateCreated desc").fetch(page, 100);
return new TweetList(l);
}
我也有這個小包裝類:
@XmlRootElement(name = "tweetList")
private class TweetList {
private List<Tweet> tweets;
public TweetList(List<Tweet> tweets) {
this.tweets = tweets;
}
public TweetList() {
}
@XmlElement(name = "tweet")
public List<Tweet> getTweets() {
return tweets;
}
public void setTweets(List<Tweet> tweets) {
this.tweets = tweets;
}
}
在客戶端,我也有類似的包裝類和的RESTEasy代理創建一個客戶端界面,它看起來像這樣:
@GET
@Path("/tweets/all")
@Produces("application/xml")
public TweetList all(@QueryParam("page") @DefaultValue("1") Integer page);
我對獲取數據代碼:
Tweet tweet = ProxyFactory.create(Tweet.class, "http://localhost:9000/rest");
TweetList tweetList = tweet.all(null);
for(rest.client.beans.Tweet t : tweetList.getTweets()){
System.out.printf("%s wrote %s, %s \n", t.author.fullName, t.content, t.id);
}
這對於XML來說非常適用 - 所有的tweets都應該在屏幕上打印。問題是我想使用JSON作爲返回格式。當我改變我的資源和代理@Produces註解@Produces( 「應用/ JSON」),我收到此錯誤信息:
Unrecognized field "tweetList" (Class rest.client.wrappers.TweetList), not marked as ignorable
我的客戶端包裝:
@XmlRootElement(name = "tweetList")
public class TweetList {
private List<Tweet> tweets;
public TweetList(List<Tweet> tweets) {
this.tweets = tweets;
}
public TweetList() {
}
public List<Tweet> getTweets() {
return tweets;
}
@XmlElement(name = "tweet")
public void setTweets(List<Tweet> tweets) {
this.tweets = tweets;
}
}
我不知道如何繞過這個問題。從手叫我的資源在瀏覽器輸出示例:
XML:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<tweetList>
<tweet>
<id>129</id>
<content>aksjdlkajsdlkjaskjdajdlakjsdljasdlkjakdjaljdlkajsd kajsdlkajsdl kajsdlkajsdl asdlkja lkdsjalksd</content>
<author>
<id>1</id>
<login>admin</login>
<fullName>Administrator</fullName>
</author>
<dateCreated>2011-06-13T21:08:03.145+02:00</dateCreated>
</tweet>
<tweet>
<id>98</id>
<content>Donec pulvinar porta feugiat. Sed adipiscing eros at libero mollis commodo. Duis auctor, tortor ac ultricies facilisis, purus velit fermentum elit, id luctus diam enim et felis.</content>
<author>
<id>2</id>
<login>user1</login>
<fullName>UserOne</fullName>
</author>
<dateCreated>2011-04-30T02:00:00+02:00</dateCreated>
</tweet>
</tweetList>
JSON:
{
"tweetList":{
"tweet":[
{
"id":129,
"content":"aksjdlkajsdlkjaskjdajdlakjsdljasdlkjakdjaljdlkajsd kajsdlkajsdl kajsdlkajsdl asdlkja lkdsjalksd",
"author":{
"id":1,
"login":"admin",
"fullName":"Administrator"
},
"dateCreated":"2011-06-13T21:08:03.145+02:00"
},
{
"id":98,
"content":"Donec pulvinar porta feugiat. Sed adipiscing eros at libero mollis commodo. Duis auctor, tortor ac ultricies facilisis, purus velit fermentum elit, id luctus diam enim et felis.",
"author":{
"id":2,
"login":"user1",
"fullName":"UserOne"
},
"dateCreated":"2011-04-30T02:00:00+02:00"
}
]
}
}
我按照你的建議移動了這個註解,但沒有任何改變。從拋出的異常中我可以看出,我看到傑克遜被使用了。 – jjczopek
