CXF+Spring+Tomcat简明示例

多系统（异构系统）进行交互时，一种良好的方式便是调用Web Service，本示例基于Apache组织的CXF，为了方便起见特将服务端和客户端写在同一个工程下，实际项目中是不可能的，但是客户端却依赖于服务端的Web Service接口，那么可以通过导出jar的方式。

环境：
MyEclipse10
JDK6
Tomcat7
CXF2.5
Spring3

示例项目结构图：


如上图所示，全部依赖的第三方库都在lib中，下面贴出全部代码。
IHelloService.java
package bing.server;

import javax.jws.WebService;

/**
* <p>
* WebService接口
* </p>
*
* @author IceWee
* @date 2012-7-6
* @version 1.0
*/
@WebService
public interface IHelloService {

    public String sayHello(String username);
   
}

HelloServiceImpl.java
package bing.server;

import javax.jws.WebService;

/**
* <p>
* WebService实现类
* </p>
*
* @author IceWee
* @date 2012-7-6
* @version 1.0
*/
@WebService(endpointInterface = "bing.server.IHelloService", serviceName = "HelloService")
public class HelloServiceImpl implements IHelloService {

    @Override
    public String sayHello(String username) {
        return "hello, " + username;
    }

}

HelloServiceClient.java
package bing.client;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import bing.server.IHelloService;

/**
* <p>
* WebService调用方-客户端
* </p>
*
* @author IceWee
* @date 2012-7-6
* @version 1.0
*/
public class HelloServiceClient {

    public static void main(String[] args) {
        ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext-client.xml");
        IHelloService helloService = (IHelloService) context.getBean("client");
        String response = helloService.sayHello("Peter");
        System.out.println(response);
    }

}

所有项目都已配置完成，可以发布到Tomcat了，在浏览器中输入：http://localhost:8080/CXFDemo/ws，返回如图：


从上图中可以看到我们对外发布的WebService接口，点击蓝色超链接，返回如图：

到此，证明我们的Web Service已经发布成功，可以进行调用测试了。运行HelloServiceClient，返回如图：

Java Tomcat SSL 服务端/客户端双向认证のApache HttpClient（二）

本演示例程是继Java Tomcat SSL 服务端/客户端双向认证（一），密钥库可证书的生成脚本不再重复黏贴，仅仅是用程序来代替浏览器访问服务端。
例程中使用到了Apache HttpClient库，版本为4.1.3
全部依赖库：
commons-logging-1.1.1.jar
httpclient-4.1.3.jar
httpcore-4.1.4.jar
httpmime-4.1.3.jar(上传文件使用)

在（一）中的程序包中创建一个客户端类：HttpsClient
HttpsClient.java
package com.icesoft.client;

import java.io.BufferedReader;
import java.io.File;
import java.io.FileInputStream;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.security.KeyStore;

import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.conn.scheme.Scheme;
import org.apache.http.conn.ssl.SSLSocketFactory;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.http.util.EntityUtils;

public class HttpsClient {
   
    private static final String KEY_STORE_TYPE_JKS = "jks";
    private static final String KEY_STORE_TYPE_P12 = "PKCS12";
    private static final String SCHEME_HTTPS = "https";
    private static final int HTTPS_PORT = 8443;
    private static final String HTTPS_URL = "https://127.0.0.1:8443/HttpClientSSL/sslServlet";
    private static final String KEY_STORE_CLIENT_PATH = "E:/ssl/client.p12";
    private static final String KEY_STORE_TRUST_PATH = "E:/ssl/client.truststore";
    private static final String KEY_STORE_PASSWORD = "123456";
    private static final String KEY_STORE_TRUST_PASSWORD = "123456";

    public static void main(String[] args) throws Exception {
        ssl();
    }
   
    private static void ssl() throws Exception {
        HttpClient httpClient = new DefaultHttpClient();
        try {
            KeyStore keyStore  = KeyStore.getInstance(KEY_STORE_TYPE_P12);
            KeyStore trustStore  = KeyStore.getInstance(KEY_STORE_TYPE_JKS);
            InputStream ksIn = new FileInputStream(KEY_STORE_CLIENT_PATH);
            InputStream tsIn = new FileInputStream(new File(KEY_STORE_TRUST_PATH));
            try {
                keyStore.load(ksIn, KEY_STORE_PASSWORD.toCharArray());
                trustStore.load(tsIn, KEY_STORE_TRUST_PASSWORD.toCharArray());
            } finally {
                try { ksIn.close(); } catch (Exception ignore) {}
                try { tsIn.close(); } catch (Exception ignore) {}
            }
            SSLSocketFactory socketFactory = new SSLSocketFactory(keyStore, KEY_STORE_PASSWORD, trustStore);
            Scheme sch = new Scheme(SCHEME_HTTPS, HTTPS_PORT, socketFactory);
            httpClient.getConnectionManager().getSchemeRegistry().register(sch);
            HttpGet httpget = new HttpGet(HTTPS_URL);
            System.out.println("executing request" + httpget.getRequestLine());
            HttpResponse response = httpClient.execute(httpget);
            HttpEntity entity = response.getEntity();
            System.out.println("----------------------------------------");
            System.out.println(response.getStatusLine());
            if (entity != null) {
                System.out.println("Response content length: " + entity.getContentLength());
                BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(entity.getContent()));
                String text;
                while ((text = bufferedReader.readLine()) != null) {
                    System.out.println(text);
                }
                bufferedReader.close();
            }
            EntityUtils.consume(entity);
        } finally {
            httpClient.getConnectionManager().shutdown();
        }
    }

}


启动Tomcat，运行HttpsClient，控制台返回：


OK，和使用浏览器访问得到的结果一模一样！

Java Tomcat SSL 服务端/客户端双向认证（一）

     摘要: SSL——Secure Sockets Layer双向认证(个人理解)：客户端认证：客户端通过浏览器访问某一网站时，如果该网站为HTTPS网站，浏览器会自动检测系统中是否存在该网站的信任证书，如果没有信任证书，浏览器一般会拒绝访问，IE会有一个继续访问的链接，但地址栏是红色，给予用户警示作用，即客户端验证服务端并不是强制性的，可以没有服务端的信任证书，当然是否继续访问完全取...  阅读全文

Java MD5校验工具类

     摘要: 之前使用到了NIO的FileChannel做文件快速阅读，后来发现存在一个巨大的BUG，使用它会一直不释放文件句柄，即生成MD5的文件不能操作（移动或删除等），这个BUG网上吵得沸沸扬扬，至今没有解决，毕竟是SUN的BUG，解铃还需系铃人啊！咱只好乖乖的使用文件分块读取的方法，这种方式要求生成MD5和验证的时候得使用相同的缓存大小。MD5Utils.javaCode highlighting pr...  阅读全文
