怎样使用JS中EL表达式获取上下文参数

/**
 * 测试js中获取后台传值
 * @param model
 * @param req
 * @return	String
 */
@RequestMapping("getValue")
public String getValue(Model model, HttpServletRequest req){
	model.addAttribute("stringValue", "测试在js中取值...");
	model.addAttribute("numberValue", 111);
	List<String> list = new ArrayList<String>();
	list.add("aaa");
	list.add("bbb");
	list.add("ccc");
	model.addAttribute("arrayValue", list);
	model.addAttribute("jsonStringValue", JSON.toJSONString(list));
	User user = new User();
	user.setUserID("1");
	user.setUserName("test");
	user.setMobile("13800000000");
	user.setEmail("test@163.com");
	user.setNickName("test");
	model.addAttribute("objJsonString", JSON.toJSONString(user));
	return "/getValue.htm";
}

<script type="text/javascript">
	$(function(){
	var stringValue = '${stringValue}';
	console.log('stringValue-------------' + stringValue);
	
	var numberValue = ${numberValue};
	console.log('numberValue-------------' + numberValue);
	
	var jsonStringValue = ${jsonStringValue};
	console.log('jsonValue---------------' + jsonStringValue);
	
	var jsonStringValue1 = '${jsonStringValue}';
	console.log('jsonValue1---------------' + jsonStringValue1); 
	
	var objJsonString = '${objJsonString}';
	console.log("objJsonString------------------- " + objJsonString);
	var obj = JSON.parse(objJsonString);
	console.log("userName ------------ " + obj.userName);
	});
</script>
