在Web服务中添加此方法后,我在apache tomcat Web服务中收到错误的服务:
public String getAllEvent() {
JSONArray jsonArray = new JSONArray();
try {
Class.forName("com.mysql.jdbc.Driver");
Connection con = DriverManager.getConnection(
"jdbc:mysql://localhost/mydb", "root", "root");
PreparedStatement statement = con
.prepareStatement("SELECT * FROM event");
ResultSet result = statement.executeQuery();
while (result.next()) {
JSONObject eventInfo = new JSONObject();
eventInfo.put("eventID", result.getString("eventID"));
eventInfo.put("eventName", result.getString("eventName"));
eventInfo.put("eventDesc", result.getString("eventDesc"));
eventInfo.put("eventDate", result.getString("eventDate"));
eventInfo.put("eventTime", result.getString("eventTime"));
eventInfo.put("eventX", result.getString("eventX"));
eventInfo.put("eventY", result.getString("eventY"));
eventInfo.put("eventBy", result.getString("eventBy"));
jsonArray.put(eventInfo);
}
String jsonStr = jsonArray.toString();
return jsonStr;
}
catch (JSONException je) {
return null;
} catch (Exception exc) {
System.out.println(exc.getMessage());
}
return jsonArray.toString();
}
对于此方法,我将从数据库检索的数据传递给JSON。添加后,当我在服务器上运行Web服务时,收到此错误消息:
Faculty Services:
C:\Users\Desktop\Eclipse EE\workspace\.metadata\.plugins\org.eclipse.wst.server.core\tmp1\wtpwebapps\SplashWebService\WEB-INF\services\SplashWebService
删除此方法后,Web服务再次完美运行。有任何想法吗?
提前致谢。
