Android App网络通信Retrofit
1、新建一个RetrofitInstance类
public class RetrofitInstance{}
2、建立构造函数
public class RetrofitInstance{
private RetrofitInstance(){
//这里设置通信的过程
}
}
3、通信的过程设置
设置静态变量baseURL，webURL，变量mHttpClientManager
public static String baseURL ="";//后端网址和端口
public static String webURL = “”;//web端项目存放地址
public HttpClientManager mHttpClientManager = null;//管理通信的控制中心
设置流程：建立一个OKHttpClient客户端，启用Retrofit，创建控制器，实例化RetrofitInstance实例

	private static final OkHttpClient client = new OkHttpClient.Builder()
	.connectTimeout(10, TimeUnit.SECONDS)
	.readTimeout(60, TimeUnit.SECONDS)
	.writeTimeout(60, TimeUnit.SECONDS).build();
	
 	Retrofit retrofit = new Retrofit.Builder()
 			.baseUrl(baseURL)
 			.client(client)
 			.addConverterFactory(GsonConverterFactory.create())
 			.build();
	 mHttpClientManager = rotrofit.create(HttpClientManager.class)

public static RetrofitInstance getInstance(){
return new RetrofitInstance();}

4、其中控制中心的是一个接口，所有访问的接口都集中在这里
如：/用户登录接口/

		@POST("login")
		Call<ResponseBody> login(@QueryMap Map<String,String> params);

5、详细的过程：

public class RetrofitInstance {
public static String baseURL = "http://127.0.0:8080/";
public static String webURL = "http://111.11.1.1:8080/Employee-web";
public HttpClientManager mHttpClientManager = null;

private static final OkHttpClient client = new OkHttpClient.Builder().
        connectTimeout(10, TimeUnit.SECONDS).
        readTimeout(60, TimeUnit.SECONDS).
        writeTimeout(60, TimeUnit.SECONDS).build();

private RetrofitInstance(){
    mHttpClientManager = null;
    Retrofit retrofit = new Retrofit.Builder()
                .baseUrl(baseURL)
                .client(client)
                .addConverterFactory(GsonConverterFactory.create())
                .build();

    mHttpClientManager = retrofit.create(HttpClientManager.class);
}
public static RetrofitInstance getInstance(){
    return new RetrofitInstance();
}

}
