我遇到了同样的问题。这是我的解决方案：
首先，我以与您相同的方式处理 SSL（我使用了 Bob Lee 的方法）。
Cookie 是另一回事。我过去在没有 RestTemplate 的情况下处理 cookie 的方式（即直接使用 Apache 的 HttpClient 类）是将 HttpContext 的实例传递给 HttpClient 的 execute 方法。让我们退后一步……
HttpClient 有许多重载的execute 方法，其中之一是：
execute(HttpUriRequest request, HttpContext context)
HttpContext 的实例可以引用 CookieStore。当你创建一个 HttpContext 实例时，提供一个 CookieStore（一个新的，或者你从之前的请求中保存的）：
private HttpContext createHttpContext() {
CookieStore cookieStore = (CookieStore) StaticCacheHelper.retrieveObjectFromCache(COOKIE_STORE);
if (cookieStore == null) {
Log.d(getClass().getSimpleName(), "Creating new instance of a CookieStore");
// Create a local instance of cookie store
cookieStore = new BasicCookieStore();
}
// Create local HTTP context
HttpContext localContext = new BasicHttpContext();
// Bind custom cookie store to the local context
localContext.setAttribute(ClientContext.COOKIE_STORE, cookieStore);
return localContext;
}
当然，如果您愿意，您可以在发送请求之前将 cookie 添加到 CookieStore 的实例中。现在当你调用 execute 方法时，使用 HttpContext 的那个实例：
HttpResponse response = httpClient.execute(httpRequester, localContext);
（其中 httpRequester 是 HttpPost、HttpGet 等的实例）
如果您需要在后续请求中重新发送任何 cookie，请确保将 cookie 存储在某处：
StaticCacheHelper.storeObjectInCache(COOKIE_STORE, localContext.getAttribute(ClientContext.COOKIE_STORE), MAX_MILLISECONDS_TO_LIVE_IN_CACHE);
这段代码中使用的StaticCacheHelper类只是一个自定义类，可以将数据存储在静态Map中：
public class StaticCacheHelper {
private static final int TIME_TO_LIVE = 43200000; // 12 hours
private static Map<String, Element> cacheMap = new HashMap<String, Element>();
/**
* Retrieves an item from the cache. If found, the method compares
* the object's expiration date to the current time and only returns
* the object if the expiration date has not passed.
*
* @param cacheKey
* @return
*/
public static Object retrieveObjectFromCache(String cacheKey) {
Element e = cacheMap.get(cacheKey);
Object o = null;
if (e != null) {
Date now = new Date();
if (e.getExpirationDate().after(now)) {
o = e.getObject();
} else {
removeCacheItem(cacheKey);
}
}
return o;
}
/**
* Stores an object in the cache, wrapped by an Element object.
* The Element object has an expiration date, which will be set to
* now + this class' TIME_TO_LIVE setting.
*
* @param cacheKey
* @param object
*/
public static void storeObjectInCache(String cacheKey, Object object) {
Date expirationDate = new Date(System.currentTimeMillis() + TIME_TO_LIVE);
Element e = new Element(object, expirationDate);
cacheMap.put(cacheKey, e);
}
/**
* Stores an object in the cache, wrapped by an Element object.
* The Element object has an expiration date, which will be set to
* now + the timeToLiveInMilliseconds value that is passed into the method.
*
* @param cacheKey
* @param object
* @param timeToLiveInMilliseconds
*/
public static void storeObjectInCache(String cacheKey, Object object, int timeToLiveInMilliseconds) {
Date expirationDate = new Date(System.currentTimeMillis() + timeToLiveInMilliseconds);
Element e = new Element(object, expirationDate);
cacheMap.put(cacheKey, e);
}
public static void removeCacheItem(String cacheKey) {
cacheMap.remove(cacheKey);
}
public static void clearCache() {
cacheMap.clear();
}
static class Element {
private Object object;
private Date expirationDate;
/**
* @param object
* @param key
* @param expirationDate
*/
private Element(Object object, Date expirationDate) {
super();
this.object = object;
this.expirationDate = expirationDate;
}
/**
* @return the object
*/
public Object getObject() {
return object;
}
/**
* @param object the object to set
*/
public void setObject(Object object) {
this.object = object;
}
/**
* @return the expirationDate
*/
public Date getExpirationDate() {
return expirationDate;
}
/**
* @param expirationDate the expirationDate to set
*/
public void setExpirationDate(Date expirationDate) {
this.expirationDate = expirationDate;
}
}
}
但是！！！！截至 01/2012 Spring Android 中的 RestTemplate 不允许您将 HttpContext 添加到请求的执行中！这在 Spring Framework 3.1.0.RELEASE 中得到了修复，修复是 scheduled to be migrated into Spring Android 1.0.0.RC1。
所以，当我们获得 Spring Android 1.0.0.RC1 时，我们应该能够添加上面示例中描述的上下文。在此之前，我们必须使用 ClientHttpRequestInterceptor 从请求/响应标头中添加/拉取 cookie。
public class MyClientHttpRequestInterceptor implements
ClientHttpRequestInterceptor {
private static final String SET_COOKIE = "set-cookie";
private static final String COOKIE = "cookie";
private static final String COOKIE_STORE = "cookieStore";
/* (non-Javadoc)
* @see org.springframework.http.client.ClientHttpRequestInterceptor#intercept(org.springframework.http.HttpRequest, byte[], org.springframework.http.client.ClientHttpRequestExecution)
*/
@Override
public ClientHttpResponse intercept(HttpRequest request, byte[] byteArray,
ClientHttpRequestExecution execution) throws IOException {
Log.d(getClass().getSimpleName(), ">>> entering intercept");
List<String> cookies = request.getHeaders().get(COOKIE);
// if the header doesn't exist, add any existing, saved cookies
if (cookies == null) {
List<String> cookieStore = (List<String>) StaticCacheHelper.retrieveObjectFromCache(COOKIE_STORE);
// if we have stored cookies, add them to the headers
if (cookieStore != null) {
for (String cookie : cookieStore) {
request.getHeaders().add(COOKIE, cookie);
}
}
}
// execute the request
ClientHttpResponse response = execution.execute(request, byteArray);
// pull any cookies off and store them
cookies = response.getHeaders().get(SET_COOKIE);
if (cookies != null) {
for (String cookie : cookies) {
Log.d(getClass().getSimpleName(), ">>> response cookie = " + cookie);
}
StaticCacheHelper.storeObjectInCache(COOKIE_STORE, cookies);
}
Log.d(getClass().getSimpleName(), ">>> leaving intercept");
return response;
}
}
拦截器拦截请求，在缓存中查看是否有任何 cookie 添加到请求中，然后执行请求，然后从响应中提取任何 cookie 并存储它们以供将来使用。
在请求模板中添加拦截器：
restTemplate.setRequestFactory(new HttpComponentsClientHttpRequestFactory(HttpClientHelper.createDefaultHttpClient(GET_SERVICE_URL)));
ClientHttpRequestInterceptor[] interceptors = {new MyClientHttpRequestInterceptor()};
restTemplate.setInterceptors(interceptors);
你去吧！我已经测试过了，它可以工作。这应该会让你一直坚持到 Spring Android 1.0.0.RC1，那时我们可以直接将 HttpContext 与 RestTemplate 一起使用。
希望这对其他人有所帮助！
