JsonConfig

JsonConfig config = new JsonConfig();   
    	     config.setJsonPropertyFilter(new PropertyFilter() {   
    	         public boolean apply(Object source, String name, Object value) {   
    	             if (name.equals("clubs") || name.equals("city")    //说明一下：name为容易出死循环的属性！
    	                      || name.equals("msg")) {   
    	                 return true;   
    	              } else {   
    	                 return false;   
    	              }   
    	          }   
         });
