Convert Java List to JSON

Solution : Convert Java List to JSON

需要設置正確的時區
ObjectMapper mapper = new ObjectMapper();
mapper.setTimeZone(TimeZone.getTimeZone("GMT+8"));

The solution is converts the Java List into JSON format before pass it to jQuery. In Spring controller, use Jackson (or other JSON processors)to convert the List into JSON format.

	@RequestMapping(value = "/", method = RequestMethod.GET)
	public ModelAndView getPages() {
	
		ObjectMapper mapper = new ObjectMapper();
		
		List<String> list = new ArrayList<String>();
		list.add("List A");
		list.add("List B");
		list.add("List C");
		list.add("List D");
		list.add("List E");
		
		ModelAndView model = new ModelAndView("somepage");
		
		String json = "";
		try {
			json = mapper.writeValueAsString(list);
		} catch (Exception e) {
			e.printStackTrace();
		}
		
		model.addObject("list", json);
		
		return model;

	}

Copy

html page

<script>
	$(document).ready(function() {

		var list = ${list};
		$.each(list, function( index, value ) {
			alert( index + ": " + value );
		});
		
	});
</script>

Review html source code :
