笔记

1、springmvc乱码解决

	@Autowired
	private ItemCatService itemCatService;

	@RequestMapping(value="/itemcat/list", 
			produces=MediaType.APPLICATION_JSON_VALUE + ";charset=utf-8")
	@ResponseBody
	public String getItemCatList(String callback) {
		CatResult catResult = itemCatService.getItemCatList();
		//把pojo转换成字符串
		String json = JsonUtils.objectToJson(catResult);
		//拼装返回值
		String result = callback + "(" + json + ");";
		return result;
	}
}

2、JsonProperty

public class CatNode {

	@JsonProperty("n")
	private String name;
	@JsonProperty("u")
	private String url;
	@JsonProperty("i")
	private List item;
}

3、使用此方法可以通过修改response，设置响应的数据格式，比如响应json数据

response.setCharacterEncoding("utf-8");
response.setContentType("application/json;charset=utf-8");
response.getWriter().write("json串");
