java调用webservice方法

1. java客户端调用Webservice接口流程

给你看看以前写的获取电话号码归属地的代码的三种方法，然后你就懂了。

importjava.io.ByteArrayOutputStream;
importjava.io.FileInputStream;
importjava.io.IOException;
importjava.io.InputStream;
importjava.net.HttpURLConnection;
importjava.net.URL;

importorg.apache.commons.httpclient.HttpClient;
importorg.apache.commons.httpclient.HttpException;
importorg.apache.commons.httpclient.methods.PostMethod;

publicclassMobileCodeService{

publicvoidhttpGet(Stringmobile,StringuserID)throwsException
{
//http://ws.webxml.com.cn/WebServices/MobileCodeWS.asmx/getMobileCodeInfo?mobileCode=string&userID=string
URLurl=newURL("http://ws.webxml.com.cn/WebServices/MobileCodeWS.asmx/getMobileCodeInfo?mobileCode="+mobile+"&userID="+userID);
HttpURLConnectionconn=(HttpURLConnection)url.openConnection();
conn.setConnectTimeout(5000);
conn.setRequestMethod("GET");

if(conn.getResponseCode()==HttpURLConnection.HTTP_OK)//200
{
InputStreamis=conn.getInputStream();

=newByteArrayOutputStream();//

byte[]buf=newbyte[1024];
intlen=-1;
while((len=is.read(buf))!=-1)
{
//获取结果
arrayOutputStream.write(buf,0,len);
}

System.out.println("Get方式获取的数据是:"+arrayOutputStream.toString());
arrayOutputStream.close();
is.close();
}
}


publicvoidhttpPost(Stringmobile,StringuserID)throwsHttpException,IOException
{
//访问路径http://ws.webxml.com.cn/WebServices/MobileCodeWS.asmx/getMobileCodeInfo
//HttpClient访问

HttpClienthttpClient=newHttpClient();
PostMethodpm=newPostMethod("http://ws.webxml.com.cn/WebServices/MobileCodeWS.asmx/getMobileCodeInfo");

pm.setParameter("mobileCode",mobile);
pm.setParameter("userID",userID);

intcode=httpClient.executeMethod(pm);
System.out.println("状态码:"+code);

//获取结果
Stringresult=pm.getResponseBodyAsString();
System.out.println("获取到的数据是:"+result);
}

publicvoidSOAP()throwsException
{
HttpClientclient=newHttpClient();

PostMethodmethod=newPostMethod("http://ws.webxml.com.cn/WebServices/MobileCodeWS.asmx");

//设置访问方法的参数
method.setRequestBody(newFileInputStream("C:\soap.xml"));

method.setRequestHeader("Content-Type","text/xml;charset=utf-8");

intcode=client.executeMethod(method);
System.out.println("状态码:"+code);

//获取结果
Stringresult=method.getResponseBodyAsString();
System.out.println("获取到的数据是:"+result);
}

publicstaticvoidmain(String[]args)throwsException{
MobileCodeServicemcs=newMobileCodeService();
mcs.httpGet("18524012513","");
//mcs.httpPost("18524012513","");
//mcs.SOAP();
}
}

2. JAVA怎样调用https类型的webservice

方法/步骤
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：
/**
*
*/
import java.io.BufferedReader;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.OutputStream;
import java.security.KeyStore;
import java.security.MessageDigest;
import java.security.cert.CertificateException;
import java.security.cert.X509Certificate;
import javax.net.ssl.SSLContext;
import javax.net.ssl.SSLException;
import javax.net.ssl.SSLSocket;
import javax.net.ssl.SSLSocketFactory;
import javax.net.ssl.TrustManager;
import javax.net.ssl.TrustManagerFactory;
import javax.net.ssl.X509TrustManager;
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);
}
}

}
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，

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

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，

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）

3. java语言使用post方式调用webService方式

WebService可以有Get、Post、Soap、Document四种方式调用，以下Java通过post方式调用WebService代码：

importjava.io.BufferedReader;
importjava.io.IOException;
importjava.io.InputStream;
importjava.io.InputStreamReader;
importjava.io.OutputStream;
importjava.io.OutputStreamWriter;
importjava.net.URL;
importjava.net.URLConnection;
importjava.net.URLEncoder;
importorg.apache.cxf.endpoint.Client;
importorg.apache.cxf.jaxws.endpoint.dynamic.JaxWsDynamicClientFactory;
/**
*功能描述：WebService调用
*
*/
publicclassClientTest{
/**
*功能描述：HTTP-POST
*
*/
publicStringpost(){
OutputStreamWriterout=null;
StringBuildersTotalString=newStringBuilder();
try{
URLurlTemp=newURL(
"http://www.webxml.com.cn/WebServices/WeatherWebService.asmx/getSupportCity");
URLConnectionconnection=urlTemp.openConnection();
connection.setDoOutput(true);
out=newOutputStreamWriter(connection.getOutputStream(),"UTF-8");
StringBuffersb=newStringBuffer();
sb.append("byProvinceName=福建");
out.write(sb.toString());
out.flush();
StringsCurrentLine;
sCurrentLine="";
InputStreaml_urlStream;
l_urlStream=connection.getInputStream();//请求
BufferedReaderl_reader=newBufferedReader(newInputStreamReader(
l_urlStream));
while((sCurrentLine=l_reader.readLine())!=null){
sTotalString.append(sCurrentLine);
}
}catch(Exceptione){
e.printStackTrace();
}finally{
if(null!=out){
try{
out.close();
}catch(IOExceptione){
e.printStackTrace();
}
}
}
returnsTotalString.toString();
}
}

4. java程序怎么调用webservice接口，实现发送短信功能

给你一个最简单的方法：
第一、根据http://134.224.102.6:80/CompanySendSmInf/services/SmsInf?wsdl 拿到WSDL文件。
第二、根据Axis的jar包，把WSDL文件生成客服端java代码。（可以把java文件打成jar文件，便于管理。怎么生成java代码，网络里都有说明我就不写了。）
第三、在你工程里用AXIS的功能属性，调用外部接口；给你一个格式模板：
MobileCodeWSLocator l=new MobileCodeWSLocator();//MobileCodeWSLocator是WSDL文件生成客服端java类；
MobileCodeWSSoap s=l.getMobileCodeWSSoap();();//MobileCodeWSSoap 是WSDL文件生成客服端java类

String m=s.getMobileCodeInfo("13811534742", "");
如果你用Axis生成的java类，格式和上面一样；自己参考一下就懂了。

你上面明显的连接异常，第三方服务明显没有开，WEBSERVICE可以设置户名、密码，像行所有的WEBSERVICE都设置，安全考虑吧。

5. 怎么用Java通过wsdl地址调用WebService求代码

• webservice 使用说明书，就是wsdl.

• wsdl说明是是基于xml格式的

• 通过wsdl说明书，就可以完整的描述一个服务端对外发布的服务

生成客户端调用代码：

• 语法1: wsimport -s . wsdl说明书地址

• 语法2：wsimport -keep -p 包名称 wsdl说明书地址

直接用cmd控制调用上面代码，把生成的代码直接复制到你的项目中，就可以使用了

6. java调用webservice错误:Could not send Message

看ping通要连webServiceip或者浏览器访问址看能否现xml页面报错般网络通或端口问题。
