所有已实现的接口:

```
public class HttpInvokerServiceExporter
extends RemoteInvocationSerializingExporter
implements HttpRequestHandler
```
Servlet-API-based HTTP request handler that exports the specified service bean as HTTP invoker service endpoint, accessible via an HTTP invoker proxy.
Deserializes remote invocation objects and serializes remote invocation result objects. Uses Java serialization just like RMI, but provides the same ease of setup as Caucho's HTTP-based Hessian protocol.
HTTP invoker is the recommended protocol for Java-to-Java remoting. It is more powerful and more extensible than Hessian, at the expense of being tied to Java. Nevertheless, it is as easy to set up as Hessian, which is its main advantage compared to RMI.
WARNING: Be aware of vulnerabilities due to unsafe Java deserialization: Manipulated input streams could lead to unwanted code execution on the server during the deserialization step. As a consequence, do not expose HTTP invoker endpoints to untrusted clients but rather just between your own services. In general, we strongly recommend any other message format (e.g. JSON) instead.

public void handleRequest(HttpServletRequest request,
                          HttpServletResponse response)
                   throws ServletException,
                          IOException
```
    Reads a remote invocation from the request, executes it, and writes the remote invocation result to the response.
    指定者:
    handleRequest 在接口中 HttpRequestHandler
    参数:
    request - current HTTP request
    response - current HTTP response
    抛出:
    ServletException - in case of general errors
    IOException - in case of I/O errors
    另请参阅:
    readRemoteInvocation(HttpServletRequest), RemoteInvocationBasedExporter.invokeAndCreateResult(org.springframework.remoting.support.RemoteInvocation, Object), writeRemoteInvocationResult(HttpServletRequest, HttpServletResponse, RemoteInvocationResult)
  - readRemoteInvocation

protected RemoteInvocation readRemoteInvocation(HttpServletRequest request)
                                         throws IOException,
                                                ClassNotFoundException
```
    Read a RemoteInvocation from the given HTTP request.
    Delegates to readRemoteInvocation(HttpServletRequest, InputStream) with the servlet request's input stream.
    参数:
    request - current HTTP request
    返回:
    the RemoteInvocation object
    抛出:
    IOException - in case of I/O failure
    ClassNotFoundException - if thrown by deserialization
  - readRemoteInvocation
```
protected RemoteInvocation readRemoteInvocation(HttpServletRequest request,
                                                InputStream is)
                                         throws IOException,
                                                ClassNotFoundException
```
    Deserialize a RemoteInvocation object from the given InputStream.
    Gives decorateInputStream(javax.servlet.http.HttpServletRequest, java.io.InputStream) a chance to decorate the stream first (for example, for custom encryption or compression). Creates a CodebaseAwareObjectInputStream and calls RemoteInvocationSerializingExporter.doReadRemoteInvocation(java.io.ObjectInputStream) to actually read the object.
    Can be overridden for custom serialization of the invocation.
    参数:
    request - current HTTP request
    is - the InputStream to read from
    返回:
    the RemoteInvocation object
    抛出:
    IOException - in case of I/O failure
    ClassNotFoundException - if thrown during deserialization
  - decorateInputStream
```
protected InputStream decorateInputStream(HttpServletRequest request,
                                          InputStream is)
                                   throws IOException
```
    Return the InputStream to use for reading remote invocations, potentially decorating the given original InputStream.
    The default implementation returns the given stream as-is. Can be overridden, for example, for custom encryption or compression.
    参数:
    request - current HTTP request
    is - the original InputStream
    返回:
    the potentially decorated InputStream
    抛出:
    IOException - in case of I/O failure
  - writeRemoteInvocationResult
```
protected void writeRemoteInvocationResult(HttpServletRequest request,
                                           HttpServletResponse response,

                                    throws IOException
```
    Write the given RemoteInvocationResult to the given HTTP response.
    参数:
    request - current HTTP request
    response - current HTTP response
    result - the RemoteInvocationResult object
    抛出:
    IOException - in case of I/O failure
  - writeRemoteInvocationResult

                                    throws IOException
```
    Serialize the given RemoteInvocation to the given OutputStream.
    The default implementation gives decorateOutputStream(javax.servlet.http.HttpServletRequest, javax.servlet.http.HttpServletResponse, java.io.OutputStream) a chance to decorate the stream first (for example, for custom encryption or compression). Creates an ObjectOutputStream for the final stream and calls RemoteInvocationSerializingExporter.doWriteRemoteInvocationResult(org.springframework.remoting.support.RemoteInvocationResult, java.io.ObjectOutputStream) to actually write the object.
    Can be overridden for custom serialization of the invocation.
    参数:
    request - current HTTP request
    response - current HTTP response
    result - the RemoteInvocationResult object
    os - the OutputStream to write to
    抛出:
    IOException - in case of I/O failure
