如何设计Spring MVC REST服务？ [英] How to design a Spring MVC REST service?

问题描述

我希望客户端和服务器应用程序使用REST服务相互通信。我一直在尝试使用Spring MVC来设计它。我正在寻找这样的东西：

I want the client and server application to talk to each other using REST services. I have been trying to design this using Spring MVC. I am looking for something like this:

1. 客户端进行POST休息服务调用 saveEmployee（employeeDTO，companyDTO）


2. 服务器在其控制器中有类似的POST方法 saveEmployee（employeeDTO，companyDTO）

1. Client does a POST rest service call saveEmployee(employeeDTO, companyDTO)
2. Server has a similar POST method in its controller saveEmployee(employeeDTO, companyDTO)

这可以使用Spring MVC完成吗？

Can this be done using Spring MVC?

推荐答案

是的，这可以做到。这是RESTful Controller的一个简单示例（带有Spring注释）：

Yes, this can be done. Here's a simple example (with Spring annotations) of a RESTful Controller:

@Controller
@RequestMapping("/someresource")
public class SomeController
{
    @Autowired SomeService someService;

    @RequestMapping(value="/{id}", method=RequestMethod.GET)
    public String getResource(Model model, @PathVariable Integer id)
    {
        //get resource via someService and return to view
    }

    @RequestMapping(method=RequestMethod.POST)
    public String saveResource(Model model, SomeResource someREsource)
    {
        //store resource via someService and return to view
    }

    @RequestMapping(value="/{id}", method=RequestMethod.PUT)
    public String modifyResource(Model model, @PathVariable Integer id, SomeResource someResource)
    {
        //update resource with given identifier and given data via someService and return to view
    }

    @RequestMapping(value="/{id}", method=RequestMethod.DELETE)
    public String deleteResource(Model model, @PathVariable Integer id)
    {
        //delete resource with given identifier via someService and return to view
    }
}

请注意，处理传入的方式有多种来自http-request的数据（@RequestParam，@ RequestBody，后参数自动映射到bean等）。对于更长和可能更好的解释和教程，尝试使用谷歌搜索'rest spring mvc'（不带引号）。

Note that there are multiple ways of handling the incoming data from http-request (@RequestParam, @RequestBody, automatic mapping of post-parameters to a bean etc.). For longer and probably better explanations and tutorials, try googling for something like 'rest spring mvc' (without quotes).

通常客户端（浏览器）-stuff完成JavaScript和AJAX，我是服务器后端程序员，并不了解很多JavaScript，但有很多库可以帮助它，例如参见 jQuery

Usually the clientside (browser) -stuff is done with JavaScript and AJAX, I'm a server-backend programmer and don't know lots about JavaScript, but there are lots of libraries available to help with it, for example see jQuery
