解析前的对象：

生成的代码：
try {
//数据库查询
ResultSet rs = dd.query(sql, count);
while(rs.next()) {
BBSInformation bbsInfo = new BBSInformation();
bbsInfo.setBBSUUID(rs.getString("article_uuid"));
bbsInfo.setBBSAuthor("article_author");
bbsInfo.setBBSTime(rs.getDate("article_date").toString());
bbsInfo.setBBSTitle(rs.getString("article_title"));

bbsInfo.setBBSAgree(rs.getInt("article_agree"));

bbsInfo.setBBSCommentNum(rs.getInt("article_comment"));
bbsInformations.add(bbsInfo);
}
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
System.out.println(bbsInformations.get(0).getBBSAuthor());
/*GetBBSIformation getBBSIformation = new GetBBSIformation();
getBBSIformation.setList(bbsInformations);*/
Gson gson = new Gson();
String bbsInfoJson = new WriteJson().getJsonData(bbsInformations);
System.out.println(bbsInfoJson);
response.setContentType("text/xml; charset=UTF-8");
PrintWriter out = response.getWriter();
out.println(bbsInfoJson);
out.flush();
out.close();
生成的jsonString:
[{"BBSAuthor":"article_author","BBSContent":"我是一只小小小鸟","BBSTime":"1994-06-17","BBSKeywords":"android,java,c语言","BBSAgree":5,"BBSDisagree":2,"BBSCommentNum":3,"BBSUUID":"254ebfed-90d2-464f-a76b-a55aed6e8fb7"}]
解析的源代码：
Type listType = new TypeToken>(){}.getType();
Gson gson=new Gson();
List list=gson.fromJson(jsondata, listType);
生成json和解析json用的是同一个对象BBSInformation,，弄了好久啊，
就是到这里，没有返回list，求告知是什么原因？
