1 使用HttpServletResponse来处理--不需要配置解析器
@Controller
public class AjaxController {
@RequestMapping("/ajax")
public void ajax(String name,HttpServletResponse resp) throws IOException{
if ("sgcc".equals(name)) {
resp.getWriter().print("true");
System.out.println("true");
}else {
resp.getWriter().print("false");
}
}
}
