在工作中，遇到需要开放一个web接口给对方调用，所以用到了HttpInvoker ，但是又遇到了一个问题，就是采用的是双向认证，只开放443端口，也就是说配置接口必须采用https，而且调用接口时，还需要通过双向认证。下面是我做的事例，贴出来供大家参考。
一、创建接口和接口实现类
public interface SyncRemoteService {
/**
* 挂网成功后需要更新数据列表
*
* @return List<List<String>>
*/
public void syncBackDatas(List<List<String>> syncDatas);
/**
* 挂网成功后需要更新数据内容
*
* @param json 字符串
*/
public void syncBackData(String json);
}
二、HttpInvoker 服务端配置
applicationContext.xml
<!-- 挂网返回结果接口 -->
<bean id ="syncRemoteService" class = "com.noah.nrmp.resource.file.service.impl.SyncRemoteServiceImpl" />
<bean name ="syncRemoteServiceExporter" class = "org.springframework.remoting.httpinvoker.HttpInvokerServiceExporter" >
<property name = "service" ref = "syncRemoteService" />
<property name = "serviceInterface" value = "com.noah.nrmp.resource.file.service.SyncRemoteService" />
</bean>
web.xml 文件配置
<servlet>
<servlet-name>syncRemoteServiceExporter</servlet-name>
<servlet-class>org.springframework.web.context.support.HttpRequestHandlerServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>syncRemoteServiceExporter</servlet-name>
<url-pattern>/SyncRemoteService</url-pattern>
</servlet-mapping>
二、HttpInvoker 客户端配置
需要commons-httpclient-3.1.jar包，还需要什么依赖包，自己查下资料吧
applicationContext.xml
<bean id="syncRemoteService"
class="org.springframework.remoting.httpinvoker.HttpInvokerProxyFactoryBean">
<property name="serviceUrl"
value="https://www.nrmp2.anoah/NRMP_TEST/SyncRemoteService" />
<property name="serviceInterface" value="com.noah.nrmp.resource.file.service.SyncRemoteService" />
<property name="httpInvokerRequestExecutor">
<bean class="com.noah.nrmp.resource.file.service.SSLCommonsHttpInvokerRequestExecutor"/>
</property>
</bean>
因为这里需要双向认证，所以我自己实现了CommonsHttpInvokerRequestExecutor，方便加入SSL证书
SSLCommonsHttpInvokerRequestExecutor 内容如下：
public class SSLCommonsHttpInvokerRequestExecutor extends CommonsHttpInvokerRequestExecutor {
private HttpClient httpClient;
@SuppressWarnings("deprecation")
public SSLCommonsHttpInvokerRequestExecutor(){
Protocol.registerProtocol("https", new Protocol("https", new SimpleSSLTestProtocolSocketFactory(),443));
this.httpClient = new HttpClient(new MultiThreadedHttpConnectionManager());
}
public SSLCommonsHttpInvokerRequestExecutor(HttpClient httpClient) {
this.httpClient = httpClient;
}
@Override
public void setHttpClient(HttpClient httpClient) {
this.httpClient = httpClient;
}
@Override
public HttpClient getHttpClient() {
return httpClient;
}
}
关键是加入这句话：Protocol.registerProtocol("https", new Protocol("https", new SimpleSSLTestProtocolSocketFactory(),443));
在SimpleSSLTestProtocolSocketFactory中加载客户端证书和服务端证书
SimpleSSLTestProtocolSocketFactory 内容如下：
public class SimpleSSLTestProtocolSocketFactory implements SecureProtocolSocketFactory {
private static final Log LOG = LogFactory.getLog(SimpleSSLTestProtocolSocketFactory.class);
private static SSLContext SSLCONTEXT = null;
private static SSLContext createSSLContext() {
try {
KeyStore keystore = KeyStore.getInstance("PKCS12");
FileInputStream ksInstream = new FileInputStream(new File("D:\\client.p12"));
KeyStore trustStore = KeyStore.getInstance(KeyStore.getDefaultType());
FileInputStream trustInstream = new FileInputStream(new File("D:\\jssecacerts"));
try {
keystore.load(ksInstream, "test".toCharArray());
trustStore.load(trustInstream, "change".toCharArray());
} finally {
if (ksInstream != null)
ksInstream.close();
if (trustInstream!=null)
trustInstream.close();
}
KeyManagerFactory keyManagerFactory = KeyManagerFactory.getInstance(KeyManagerFactory.getDefaultAlgorithm());
TrustManagerFactory trustManagerFactory = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());
keyManagerFactory.init(keystore, "test".toCharArray());
trustManagerFactory.init(trustStore);
KeyManager[] keymanagers=keyManagerFactory.getKeyManagers();
TrustManager[] trustmanagers = trustManagerFactory.getTrustManagers();
SSLContext sslcontext = SSLContext.getInstance("TLS");
sslcontext.init(keymanagers, trustmanagers, null);
return sslcontext;
} catch (Exception ex) {
LOG.error(ex.getMessage(), ex);
throw new IllegalStateException(ex.getMessage());
}
}
private static SSLContext getSSLContext() {
if (SSLCONTEXT == null) {
SSLCONTEXT = createSSLContext();
}
return SSLCONTEXT;
}
public SimpleSSLTestProtocolSocketFactory() {
super();
}
public Socket createSocket(final String host, final int port,
final InetAddress localAddress, final int localPort,
final HttpConnectionParams params) throws IOException,
UnknownHostException, ConnectTimeoutException {
if (params == null) {
throw new IllegalArgumentException("Parameters may not be null");
}
int timeout = params.getConnectionTimeout();
if (timeout == 0) {
return createSocket(host, port, localAddress, localPort);
} else {
// To be eventually deprecated when migrated to Java 1.4 or above
return ControllerThreadSocketFactory.createSocket(this, host, port,
localAddress, localPort, timeout);
}
}
public Socket createSocket(String host, int port, InetAddress clientHost,
int clientPort) throws IOException, UnknownHostException {
return getSSLContext().getSocketFactory().createSocket(host, port,
clientHost, clientPort);
}
public Socket createSocket(String host, int port) throws IOException,
UnknownHostException {
return getSSLContext().getSocketFactory().createSocket(host, port);
}
public Socket createSocket(Socket socket, String host, int port,
boolean autoClose) throws IOException, UnknownHostException {
return getSSLContext().getSocketFactory().createSocket(socket, host,
port, autoClose);
}
}
其中 keystore.load(ksInstream, "test".toCharArray());
trustStore.load(trustInstream, "changeit".toCharArray());
test 和changeit为证书密码
FileInputStream trustInstream = new FileInputStream(new File("D:\\jssecacerts"));
jssecacerts 文件生成代码 如下：
public class InstallCert {
public static void main(String[] args) throws Exception {
String host;
int port;
char[] passphrase;
if ((args.length == 1) || (args.length == 2)) {
String[] c = args[0].split(":");
host = c[0];
port = (c.length == 1) ? 443 : Integer.parseInt(c[1]);
String p = (args.length == 1) ? "changeit" : args[1];
passphrase = p.toCharArray();
} else {
System.out.println("Usage: java InstallCert <host>[:port] [passphrase]");
return;
}
File file = new File("jssecacerts");
if (file.isFile() == false) {
char SEP = File.separatorChar;
File dir = new File(System.getProperty("java.home") + SEP
+ "lib" + SEP + "security");
file = new File(dir, "jssecacerts");
if (file.isFile() == false) {
file = new File(dir, "cacerts");
}
}
System.out.println("Loading KeyStore " + file + "...");
InputStream in = new FileInputStream(file);
KeyStore ks = KeyStore.getInstance(KeyStore.getDefaultType());
ks.load(in, passphrase);
in.close();
SSLContext context = SSLContext.getInstance("TLS");
TrustManagerFactory tmf =
TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());
tmf.init(ks);
X509TrustManager defaultTrustManager = (X509TrustManager) tmf.getTrustManagers()[0];
SavingTrustManager tm = new SavingTrustManager(defaultTrustManager);
context.init(null, new TrustManager[]{tm}, null);
SSLSocketFactory factory = context.getSocketFactory();
System.out.println("Opening connection to " + host + ":" + port + "...");
SSLSocket socket = (SSLSocket) factory.createSocket(host, port);
socket.setSoTimeout(10000);
try {
System.out.println("Starting SSL handshake...");
socket.startHandshake();
socket.close();
System.out.println();
System.out.println("No errors, certificate is already trusted");
} catch (SSLException e) {
System.out.println();
e.printStackTrace(System.out);
}
X509Certificate[] chain = tm.chain;
if (chain == null) {
System.out.println("Could not obtain server certificate chain");
return;
}
BufferedReader reader =
new BufferedReader(new InputStreamReader(System.in));
System.out.println();
System.out.println("Server sent " + chain.length + " certificate(s):");
System.out.println();
MessageDigest sha1 = MessageDigest.getInstance("SHA1");
MessageDigest md5 = MessageDigest.getInstance("MD5");
for (int i = 0; i < chain.length; i++) {
X509Certificate cert = chain[i];
System.out.println
(" " + (i + 1) + " Subject " + cert.getSubjectDN());
System.out.println(" Issuer " + cert.getIssuerDN());
sha1.update(cert.getEncoded());
System.out.println(" sha1 " + toHexString(sha1.digest()));
md5.update(cert.getEncoded());
System.out.println(" md5 " + toHexString(md5.digest()));
System.out.println();
}
System.out.println("Enter certificate to add to trusted keystore or 'q' to quit: [1]");
String line = reader.readLine().trim();
int k;
try {
k = (line.length() == 0) ? 0 : Integer.parseInt(line) - 1;
} catch (NumberFormatException e) {
System.out.println("KeyStore not changed");
return;
}
X509Certificate cert = chain[k];
String alias = host + "-" + (k + 1);
ks.setCertificateEntry(alias, cert);
OutputStream out = new FileOutputStream("jssecacerts");
ks.store(out, passphrase);
out.close();
System.out.println();
System.out.println(cert);
System.out.println();
System.out.println
("Added certificate to keystore 'jssecacerts' using alias '"
+ alias + "'");
}
private static final char[] HEXDIGITS = "0123456789abcdef".toCharArray();
private static String toHexString(byte[] bytes) {
StringBuilder sb = new StringBuilder(bytes.length * 3);
for (int b : bytes) {
b &= 0xff;
sb.append(HEXDIGITS[b >> 4]);
sb.append(HEXDIGITS[b & 15]);
sb.append(' ');
}
return sb.toString();
}
private static class SavingTrustManager implements X509TrustManager {
private final X509TrustManager tm;
private X509Certificate[] chain;
SavingTrustManager(X509TrustManager tm) {
this.tm = tm;
}
public X509Certificate[] getAcceptedIssuers() {
throw new UnsupportedOperationException();
}
public void checkClientTrusted(X509Certificate[] chain, String authType)
throws CertificateException {
throw new UnsupportedOperationException();
}
public void checkServerTrusted(X509Certificate[] chain, String authType)
throws CertificateException {
this.chain = chain;
tm.checkServerTrusted(chain, authType);
}
}
}
好了，大致就这样，就能实现HttpInvoker 双向认证 接口调用了
