Spring REST Controller中带有RequestBody的XML/JSON POST [英] XML/JSON POST with RequestBody in Spring REST Controller

问题描述

我正在用Spring 3.0创建一个RESTful网站.我正在使用ContentNegotiatingViewResolver以及HTTP消息转换器(例如MappingJacksonHttpMessageConverter用于JSON，MarshallingHttpMessageConverter用于XML等).如果我在url的末尾使用.xml后缀，并且在JSON与URL带有.json后缀的情况下相同，则能够成功获取XML内容.

I am creating a RESTful website with Spring 3.0. I am using ContentNegotiatingViewResolver as well as HTTP Message Convertors (like MappingJacksonHttpMessageConverter for JSON, MarshallingHttpMessageConverter for XML, etc.). I am able to get the XML content successfully, if I use the .xml suffix in the last of url and same in case of JSON with .json suffix in URL.

从控制器获取XML/JSON内容对我来说没有任何问题.但是，如何在同一Controller方法中以请求正文发布XML/JSON?

Getting XML/JSON contents from controller doesn't produce any problem for me. But, how can I POST the XML/JSON with request body in same Controller method?

例如

@RequestMapping(method=RequestMethod.POST, value="/addEmployee")
   public ModelAndView addEmployee(@RequestBody Employee e) {
        employeeDao.add(e);
        return new ModelAndView(XML_VIEW_NAME, "object", e);
}

推荐答案

您应该考虑不使用View返回JSON(或XML)，而应使用@ResponseBody批注.如果应该返回雇员，那么，如果您使用这样的方法定义和实现(请注意，未经测试)，Spring和MappingJacksonHttpMessageConverter会自动将Employee对象转换为JSON:

You should consider not using a View for returning JSON (or XML), but use the @ResponseBody annotation. If the employee is what should be returned, Spring and the MappingJacksonHttpMessageConverter will automatic translate your Employee Object to JSON if you use a method definition and implementation like this (note, not tested):

   @RequestMapping(method=RequestMethod.POST, value="/addEmployee")
   @ResponseBody
   public Employee addEmployee(@RequestBody Employee e) {
     Employee created = employeeDao.add(e);
     return created;
   }
