response.getWriter().write（）可以替代springMvc的返回（页面，字符）而且还可返回图片都可被ajax（字符），src（图片，完整页面字符）接收
response.getWriter().write(str);这种写入的就相当于生成了jsp/html，返回html/jsp
标签的src可以接收，页面/图片 写的方式页面（1，src加载url，这是可以springmvc方式返回，可以response.getWriter().write(str)返回）
ajax的回调函数可以接收json数据，也可以接收html/jsp，写的方式有两种1，直接springmvc返回（页面/json），2，response.getWriter().write(str)（页面/json）
@responseBody(springmvc直接json)，如果返回的是html,ajax需声明dataType:"html",不加这个返回页面，用response.getWriter().write(str)也可返回字符串
也就是说springMvc封装返回的东西src可以接收(页面，json)，ajax可以接收（页面，json）
最原生的response.getWriter().write(str)返回，src可以接收（图片，完整的页面字符），ajax也可接收（字符串）
//整个跳转页面，不是字符串拼接形式的页面字符串返回，用dataType='Html'
