public abstract class RemoteInvocationSerializingExporter
extends RemoteInvocationBasedExporter
implements org.springframework.beans.factory.InitializingBean

Abstract base class for remote service exporters that explicitly deserialize RemoteInvocation objects and serialize RemoteInvocationResult objects, for example Spring's HTTP invoker.

Provides template methods for ObjectInputStream and ObjectOutputStream handling.

RemoteInvocationSerializingExporter

public RemoteInvocationSerializingExporter()

方法详细资料

setContentType

public void setContentType(String contentType)

Specify the content type to use for sending remote invocation responses.

Default is "application/x-java-serialized-object".

getContentType

public String getContentType()

Return the content type to use for sending remote invocation responses.

setAcceptProxyClasses

public void setAcceptProxyClasses(boolean acceptProxyClasses)

Set whether to accept deserialization of proxy classes.

Default is "true". May be deactivated as a security measure.

isAcceptProxyClasses

public boolean isAcceptProxyClasses()

Return whether to accept deserialization of proxy classes.

afterPropertiesSet

public void afterPropertiesSet()

指定者:

afterPropertiesSet 在接口中 org.springframework.beans.factory.InitializingBean

prepare

public void prepare()

Initialize this service exporter.

getProxy

protected final Object getProxy()

createObjectInputStream

protected ObjectInputStream createObjectInputStream(InputStream is)
                                             throws IOException

Create an ObjectInputStream for the given InputStream.

The default implementation creates a Spring CodebaseAwareObjectInputStream.

参数:

is - the InputStream to read from

返回:

the new ObjectInputStream instance to use

抛出:

IOException - if creation of the ObjectInputStream failed

doReadRemoteInvocation

protected RemoteInvocation doReadRemoteInvocation(ObjectInputStream ois)
                                           throws IOException,
                                                  ClassNotFoundException

Perform the actual reading of an invocation result object from the given ObjectInputStream.

The default implementation simply calls ObjectInputStream.readObject(). Can be overridden for deserialization of a custom wrapper object rather than the plain invocation, for example an encryption-aware holder.

参数:

ois - the ObjectInputStream to read from

返回:

the RemoteInvocationResult object

抛出:

IOException - in case of I/O failure

ClassNotFoundException - if case of a transferred class not being found in the local ClassLoader

createObjectOutputStream

protected ObjectOutputStream createObjectOutputStream(OutputStream os)
                                               throws IOException

Create an ObjectOutputStream for the given OutputStream.

The default implementation creates a plain ObjectOutputStream.

参数:

os - the OutputStream to write to

返回:

the new ObjectOutputStream instance to use

抛出:

IOException - if creation of the ObjectOutputStream failed

doWriteRemoteInvocationResult

protected void doWriteRemoteInvocationResult(RemoteInvocationResult result,
                                             ObjectOutputStream oos)
                                      throws IOException

Perform the actual writing of the given invocation result object to the given ObjectOutputStream.

The default implementation simply calls ObjectOutputStream.writeObject(java.lang.Object). Can be overridden for serialization of a custom wrapper object rather than the plain invocation, for example an encryption-aware holder.

参数:

result - the RemoteInvocationResult object

oos - the ObjectOutputStream to write to

抛出:

IOException - if thrown by I/O methods
