Springmvc返回JSON乱码问号

@RequestMapping(value="/book/getBook.do", produces = "text/html;charset=UTF-8")
	public @ResponseBody String getBook(String name){
		 List<Book> list =bookService.getBook(); 
		 for(Book bo:list){
			 System.out.println("id:"+bo.getId()+" name:"+bo.getName()+" author:"+bo.getAuthor());
		 }
		 String json = JSONObject.toJSONString(list);
		 System.out.println("json:"+json);
		return json;
	}

在 注解处 加入 

 produces = "text/html;charset=UTF-8" 

即可推荐几个好用的Chrome 插件：
