JAVA怎样调用https类型的webservice
第一步按照Axis生成本地访问客户端，完成正常的webservice调用的开发，这里的细节我就不再描述，重点说明和http不同的地方-证书的生成和使用。这里假设需要访问的网址是https://www.abc.com ，那么就需要生成网址的安全证书设置到系统属性中，并且需要在调用代码前。如下图
第二步就是介绍怎样生成证书，先写一个InstallCert.java类放到自己电脑的D盘根目录下，（注意这个类是没有包名的）类中代码如下：

}
X509Certificate[] chain = tm.chain;
if (chain == null) {
System.out.println("Could not obtain server certificate chain");
return;
}

System.in));
System.out.println();
System.out.println("Server sent " + chain.length + " certificate(s):");
System.out.println();
MessageDigest sha1 = MessageDigest.getInstance("SHA1");

}
private static final char[] HEXDIGITS = "0123456789abcdef".toCharArray();

for (int b : bytes) {

}
public void checkServerTrusted(X509Certificate[] chain, String authType)
throws CertificateException {
this.chain = chain;
tm.checkServerTrusted(chain, authType);
}
}
}
将上面的InstallCert.java编译成InstallCert.class文件放到自己电脑的D盘根目录下。这是正常的情况下D盘根目录下会有3个文件，如下图：
打开cmd进入到d盘开始执行生成证书命令，我这里不便于那我的网址测试我用支付宝的网址来测试的，输入：java InstallCert www.alipay.com 如下图
当出现了：Enter certificate to add to trusted keystore or 'q' to quit: [1]
这行代码时，输入1，回车。正常执行完后在D盘根目录下就会出现证书“jssecacerts”文件，具体如下图：

得到证书后将证书拷贝到$JAVA_HOME/jre/lib/security目录下，我这里是win7系统，在尝试的过程中需要将证书重命名为：cacerts 放进去才会有用。（这个步骤在不同的环境和操作系统下有点不同，需要注意）
public static org.apache.http.client.HttpClient wrapClient(org.apache.http.client.HttpClient base) {
try {
SSLContext ctx = SSLContext.getInstance("TLS");
X509TrustManager tm = new X509TrustManager() {
public java.security.cert.X509Certificate[] getAcceptedIssuers() {
return null;
}
@SuppressWarnings("unused")
public void checkClientTrusted(X509Certificate[] arg0, String arg1) throws CertificateException {}
@SuppressWarnings("unused")
public void checkServerTrusted(X509Certificate[] arg0, String arg1) throws CertificateException {}
@Override
public void checkClientTrusted(
java.security.cert.X509Certificate[] chain,
String authType)
throws java.security.cert.CertificateException {
}
@Override
public void checkServerTrusted(
java.security.cert.X509Certificate[] chain,
String authType)
throws java.security.cert.CertificateException {
}
};
ctx.init(null, new TrustManager[] { tm }, null);
SSLSocketFactory ssf = new SSLSocketFactory(ctx, SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
SchemeRegistry registry = new SchemeRegistry();
registry.register(new Scheme("https", 443, ssf));
ThreadSafeClientConnManager mgr = new ThreadSafeClientConnManager(registry);
return new DefaultHttpClient(mgr, base.getParams());
} catch (Exception ex) {
ex.printStackTrace();
return null;
}
}
初始化httpclient 的时候加上：
HttpClient client = new DefaultHttpClient();
client = WebClientDevWrapper.wrapClient(client);
HttpPost post = new HttpPost(url);

去年在ITjob刘老师那边听他说过，你试试看行不行。
1.打开webService链接，右键属性—》证书—》详细信息—》复制到文件，保存cer格式的文件。
2. 复制下面的cmd命令,执行keytool命令,生成keystore文件，例如
c:\nciic.keystore
keytool -import -alias nciic -file c:\jswszx.cer -keystore c:\nciic.keystore
它会提示输入密码，随便输入，例如：123456，回车
4.他会提示是否信任这个认证，输入Y，回车,指定目录下就会生成nciic.keystore文件
它会提示输入密码，随便输入，例如：123456，回车
4.他会提示是否信任这个认证，输入Y，回车,指定目录下就会生成nciic.keystore文件
5.修改Java代码
在调用接口方法之前，添加如下代码：
System.setProperty("javax.NET.ssl.trustStore","c://nciic.keystore"); System.setProperty("java.protocol.handler.pkgs","com.sun.Net.ssl.internal.www.protocol");
java.security.Security.addProvider(new com.sun.net.ssl.internal.ssl.Provider());
