使用Spring简单的REST API调用？

本文介绍了使用Spring简单的REST API调用？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

好吧，我有一个简单的REST API，它现在正在运行。我也有一个移动应用（Android），将要准备一些网络通信。但这里的东西：

Okay I'm having a simple REST API that is now running. I also got a mobile app (Android) that would be ready for some network communication. But here is the thing:

我现在得到了与的春天，我可以以http-请求使用花哨的API：

I now got a fancy API created with Spring that I can use with Http-Requests:

package com.helloworld

@Controller
@RequestMapping("/helloWorld")
public class HelloWorldController {

    @RequestMapping(value = "/hello", method = RequestMethod.GET)
    public String hello(ModelMap model) {
        model.addAttribute("msg", "JCG Hello World!");
        return "helloWorld";
    }
}

这是所有罚款，但我怎么会用在我的Android手机应用这个API？我的意思是，我不知道如何让这些调用更优雅和简单！我不想写我的API是这样的每个请求：

This is all fine but how would I use this API in my Android mobile App? What I mean is that I don't know how to make those calls more elegantly and simple! I don't want to write for every request on my API something like this:

class HelloWorldTask extends AsyncTask<String, String, String> {

    private String url = "http://192.168.42.229:8080/HelloWorldExample/helloWorld/displayMessage/" + msg; 

    @Override
    protected String doInBackground(String... uri) {

        String msg = "";
        for(String m : uri) { msg += m; }    

        RestTemplate restTemplate = new RestTemplate();    
        restTemplate.getMessageConverters().add(new StringHttpMessageConverter());
        return restTemplate.getForObject(url, String.class, "Android");
    }
}

有什么办法避免这种情况？说实话，我相信，我将能够只导入有点像的HelloWorld-api.jar文件建设我的REST API的项目，然后做这样的事情后：

Is there any way to avoid this? To be honest I believed that I would be able to just import something like a helloworld-api.jar after building my REST API project and then do something like this:

import com.helloworld

public void getServerHello() {

    HelloWorldController api;

    HelloWorld helloWorld = api.getHelloWorldMapping();
    helloWorld.displayMessage("How are you?");
}

和，这将是它。所以写一个Spring REST API或我真的要使用像一个URI的建设者和创造各种请求的时候，有没有办法做这样的事情一个额外的类＆LT;凡是＆GT;任务延伸AsyncTask的＆LT;，＆GT;？由我自己？

And that this will be it. So is there a way to do something like this when writing a Spring REST API or will I really have to use something like a URI-builder and create for all kind of requests an additional class <whatever>Task extends AsyncTask<?, ?, ?> by myself?

由于API是明确规定它应该可以做这样的事情，但果真如此吗？

Since the API is clearly defined it should be possible to do something like this, but is it?

我希望我的问题是明确的 - 请让我知道如果不是

I hope my question is clear - please let me know if not.
