Web Service
Web Service是一种基于SOAP协议实现的跨语言Web服务调用，在Java中Web Service有如下技术实现:Oracle JWS、Apache Axis1、2、XFire、Apache CXF、JBossWS。

FileService类，提供了文件读写接口：
package com.anbai.sec.axis;
import org.apache.commons.io.FileUtils;
import java.io.File;
import java.io.IOException;
/**
* @author yz
*/
public class FileService {
public String readFile(String path) {
if (path != null && !"".equals(path)) {
File file = new File(path);
if (file.exists()) {
try {
return FileUtils.readFileToString(file, "UTF-8");
} catch (IOException e) {
return "读取文件:" + file + "异常:" + e;
}
} else {
return "文件:" + file + "不存在!";
}
} else {
return "path不能为空!";
}
}
public String writeFile(String path, String content) {
if (path != null && !"".equals(path)) {
File file = new File(path);
try {
FileUtils.writeStringToFile(file, content, "UTF-8");
return file.getAbsolutePath();
} catch (IOException e) {
return "写文件:" + file + "异常:" + e;
}
}
return "path不能为空!";
}
public String test() {
return "文件WebService测试~";
}
}
使用IDEA创建Web Service项目默认会创建管理Web Service的API:/servlet/AxisServlet、/services、SOAPMonitor、/servlet/AdminServlet，*.jws以及用监控Web Service的端口5001或5101。
访问Web Service的FileService服务加上?wsdl参数可以看到FileService提供的服务方法和具体的参数信息。
使用SOAP-UI调用Web Service接口示例：
需要注意的是Web Service也是可以设置授权认证的,如实现了WS-Security的WSS4J。
使用IDEA根据wsdl生成Web Service客户端代码：
设置wsdl地址、包名:
新建FileServiceTest类测试接口调用:
package com.anbai.sec.axis.client;
import java.net.URL;
/**
* 文件Web Service服务测试
*
* @author yz
*/
public class FileServiceTest {
public static void main(String[] args) {
try {
FileServiceService fileService = new FileServiceServiceLocator();
URL webServiceUrl = new URL("http://localhost:8080/services/FileService");
FileServiceSoapBindingStub soapService = new FileServiceSoapBindingStub(webServiceUrl, fileService);
String content = soapService.readFile("/etc/passwd");
System.out.println(content);
} catch (Exception e) {
e.printStackTrace();
}
}
}
