直接上代碼 ，一個(gè)RetrofitFactory，一個(gè)ApiFactory
package com.aidebar.retrofitutils.Utils.RetrofitUtils; import okhttp3.OkHttpClient; import retrofit2.Retrofit; import retrofit2.adapter.rxjava.RxJavaCallAdapterFactory; import retrofit2.converter.gson.GsonConverterFactory; /** * @author xzj * @date 2016/8/25 09:37. * 用于獲取配置好的retrofit對(duì)象 * 需要先調(diào)用setBaseUrl，如果項(xiàng)目中BaseUrl不變，可以寫死 */ public class RetrofitFactory { private static Retrofit retrofit; private static String baseUrl; public static void setBaseUrl(String url) { baseUrl = url; } /** * 獲取配置好的retrofit對(duì)象來(lái)生產(chǎn)Manager對(duì)象 */ public static Retrofit getRetrofit() { if (retrofit == null) { if (baseUrl == null || baseUrl.length() <= 0) throw new IllegalStateException("請(qǐng)?jiān)谡{(diào)用getFactory之前先調(diào)用setBaseUrl"); Retrofit.Builder builder = new Retrofit.Builder(); builder.baseUrl(baseUrl) .addCallAdapterFactory(RxJavaCallAdapterFactory.create()) // 參考RxJava .addConverterFactory(GsonConverterFactory.create()); // 參考與GSON的結(jié)合 // 參考自定義Log輸出 OkHttpClient client = new OkHttpClient().newBuilder() // .addInterceptor(new Interceptor() { //這個(gè)攔截器是操作請(qǐng)求頭的 // @Override // public Response intercept(Chain chain) throws IOException { // Request request = chain.request().newBuilder() // .addHeader("version", "123411") //這里就是添加一個(gè)請(qǐng)求頭 // .build(); // //// Buffer buffer = new Buffer(); 不依賴下面的Interceptor，用這三行也能打印出請(qǐng)求體 //// request.body().writeTo(buffer); //// Log.d(getClass().getSimpleName(), "intercept: " + buffer.readUtf8()); // // return chain.proceed(request); // } // }) // .addInterceptor(new HttpLoggingInterceptor().setLevel(HttpLoggingInterceptor.Level.BODY)) //這個(gè)攔截器是用來(lái)打印日志的，不穩(wěn)定 .build(); builder.client(client); retrofit = builder.build(); } return retrofit; } }package com.aidebar.retrofitutils.Utils.RetrofitUtils; import java.util.HashMap; /** * @author xzj * @date 2016/8/25 09:38. * 通過(guò)定義好的api接口以及Retrofit來(lái)生成具體的實(shí)例. */ public class ApiFactory { private static ApiFactory factory; private static HashMap<String, Object> serviceMap = new HashMap<>(); public static ApiFactory getFactory() { if (factory == null) { synchronized (ApiFactory.class) { if (factory == null) factory = new ApiFactory(); } } return factory; } public <T> T create(Class<T> clz) { Object service = serviceMap.get(clz.getName()); if (service == null) { service = RetrofitFactory.getRetrofit().create(clz); serviceMap.put(clz.getName(), service); } return (T) service; } }
還有2個(gè)是用rxjava進(jìn)行配合的可以選用
