java - 远程管理接口(interface) : RemoteAccountService extends Remote

Question

我有一个奇怪的问题，我正在阅读Spring Integration文档，在“19. Remoting and web services using Spring”部分下，有一个接口(interface)，但没有在任何地方使用。为什么文档要讨论这个接口(interface)？

public interface RemoteAccountService extends Remote {
    public void insertAccount(Account account) throws RemoteException;
    public List<Account> getAccounts(String name) throws RemoteException;
}

Answer 1

它在 19.5.1 节中为 JAX-RPC 包装器类实现。 。粘贴 19.5.1 部分的前几行下面的讨论:-

/**
 * JAX-RPC compliant RemoteAccountService implementation that simply delegates
 * to the AccountService implementation in the root web application context.
 *
 * This wrapper class is necessary because JAX-RPC requires working with dedicated
 * endpoint classes. If an existing service needs to be exported, a wrapper that
 * extends ServletEndpointSupport for simple application context access is
 * the simplest JAX-RPC compliant way.
 *
 * This is the class registered with the server-side JAX-RPC implementation.
 * In the case of Axis, this happens in "server-config.wsdd" respectively via
 * deployment calls. The web service engine manages the lifecycle of instances
 * of this class: A Spring application context can just be accessed here.
 */import org.springframework.remoting.jaxrpc.ServletEndpointSupport;

public class AccountServiceEndpoint extends ServletEndpointSupport implements RemoteAccountService {
