3. Rerun eclipse with -clean option(Windows:cmd->cd $dir_eclipse.exe->run cmd 'eclipse -clean').
4. Create a Java bean like this.

   public class TestBean {
       private String mes;
       private int[] inteters;
       private List<String> strings;
       private List<Map<String, Object>> ddd;
       private boolean klk;
       private double dst;
   }

5. Right click on file,click Builgen at the end.
