java soap + tomcat 开发

不带javaBean的SOAP调用

首先，下载soap.war，javamail.jar，activation.jar，soap.jar，xerces.jar，然后就是配置环境，如何配置就不细说了。

把soap.war扔到tomcat的webapps下，启动tomcat，访问http://127.0.0.1:8080/soap，出现Hello! Welcome to Apache-SOAP. 就说明环境搭建好了。

首先建立个java项目，包名叫soap，类名叫SOAPService，这个就是要远程调用的类

SOAPService.java：

package soap;public class SOAPService{public Person sayHi(String name){return "Hello! " + name;}}

然后打开soap的管理页面，http://127.0.0.1:8080/soap/admin

在管理页面点击“Deploy”按钮，配置部署这个类，填写基本信息如下：

ID                                        urn:HelloWorld_SOAPService
Scope                                  Application
Provider Type                      java
Provider Class                     soap.SOAPService
Use Static Class                  no
Methods                              sayHi

配置好后，编写soap的调用类SOAPClient

SOAPClient.java

package com.kt.test;import java.net.MalformedURLException;import java.net.URL;import java.util.Vector;import org.apache.soap.Constants;import org.apache.soap.Fault;import org.apache.soap.SOAPException;import org.apache.soap.rpc.Call;import org.apache.soap.rpc.Parameter;import org.apache.soap.rpc.Response;public class SOAPClient{public static void main(String[] args) throws MalformedURLException, SOAPException{Call c = null;URL url = null;Vector params = null;Response rep = null;//传入的参数名String ourName = "lws";//部署soap时的唯一标示String ourUrn = "urn:HelloWorld_SOAPService";//远程调用的方法String ourMethod = "sayHi";//soap的urlurl = new URL("http://localhost:8080/soap/servlet/rpcrouter");System.out.println("Passing to our deployed " + ourUrn + " our name ("+ ourName + "): ");c = new Call();c.setTargetObjectURI(ourUrn);c.setMethodName(ourMethod);c.setEncodingStyleURI(Constants.NS_URI_SOAP_ENC);//设置参数params = new Vector();params.addElement(new Parameter("name", String.class, ourName, null));c.setParams(params);System.out.print("and its answer is: ");//Call的invoke返回org.apache.soap.rpc.Responserep = c.invoke(url, "");//rep.generatedFault()判断请求是否成功，不成功打印错误代码，请求成功就打印远程调用返回的值if (rep.generatedFault()){Fault fault = rep.getFault();System.out.println("/nCall failed!");System.out.println("Code = " + fault.getFaultCode());System.out.println("String = " + fault.getFaultString());} else{Parameter result = rep.getReturnValue();System.out.print(result.getValue() + " === ");System.out.println();}}}

此时把SOAPService.class拷贝到tomcat主目录的webapps下的soap/WEB-INF/classes下，注意包名，重启tomcat,运行SOAPClient.java文件，就应该可以看到打印出的远程返回的字符串“Hello! lws”。

带javaBean的SOAP调用

其本上大致相同，只是在远程调用类里要手动出则一下javaBean，部署soap的时候也需要添加用户自己的javaBean

SOAPService.java

package soap;public class SOAPService{public Person sayHi(Person person){person.setName("name_1");return person;}}

在编写Person类，在相同的包(soap)下

package soap;public class Person{private String name;public String getName(){return name;}public void setName(String name){this.name = name;}}

打开http://127.0.0.1:8080/soap/admin配置该soap类，信息如下：

这是还需要配置javaBean，在Number of Mappings输入框输入1，它表示我们将给出一个映射（即Name JavaBean）的信息。紧接Mappings之下有一个表格，我们要用到这个表格的第一行。保留Encoding Style的值为SOAP，把NameSpace URI设置成对象的ID：在本例中，它是urn:Person。接下来，把Local Part和Java Type输入框设置成Name JavaBean的完整名字，即soap.Person。最后，把Java to XML Serializer和XML to Java Deserializer输入框设置成org.apache.soap.encoding.soapenc.BeanSerializer，这是一个实现了Serializer和Deserializer接口的类，用来串行化和反串行化Name JavaBean。如果你用到了更多的JavaBean（比如还有一个Address Bean），则应该在这个表格中输入其他Bean的信息，同时还应该更新Number of Mappings输入框的值，使之反映出表格中实际被使用的行数。

在SOAP调用程序中需要手工注册javaBean，完整代码如下;

SOAPClient.java

package soap;import java.net.URL;import java.util.Vector;import org.apache.soap.Constants;import org.apache.soap.Fault;import org.apache.soap.encoding.SOAPMappingRegistry;import org.apache.soap.encoding.soapenc.BeanSerializer;import org.apache.soap.rpc.Call;import org.apache.soap.rpc.Parameter;import org.apache.soap.rpc.Response;import org.apache.soap.util.xml.QName;public class SOAPClient{public static void main(String[] arg) throws Exception{Call c = null;URL url = null;Vector params = null;Response rep = null;String ourName = "lws";String ourUrn = "urn:HelloWorld_SOAPService";String ourMethod = "sayHi";url = new URL("http://localhost:8080/soap/servlet/rpcrouter");System.out.println("Passing to our deployed " + ourUrn + " our name ("+ ourName + "): ");c = new Call();c.setTargetObjectURI(ourUrn);c.setMethodName(ourMethod);c.setEncodingStyleURI(Constants.NS_URI_SOAP_ENC);// 创建类型映射注册器SOAPMappingRegistry smr = new SOAPMappingRegistry();BeanSerializer beanSer = new BeanSerializer();// 映射类型smr.mapTypes(Constants.NS_URI_SOAP_ENC,new QName("urn:Person", "soap.Person"),soap.Person.class, beanSer, beanSer);c.setSOAPMappingRegistry(smr);params = new Vector();params.addElement(new Parameter("x", Person.class, new Person(),null));c.setParams(params);System.out.print("and its answer is: ");rep = c.invoke(url, "");if (rep.generatedFault()){Fault fault = rep.getFault();System.out.println("/nCall failed!");System.out.println("Code = " + fault.getFaultCode());System.out.println("String = " + fault.getFaultString());} else{Parameter result = rep.getReturnValue();Person entity = (Person)result.getValue();System.out.print( entity.getName()+ " === ");}}}

运行该程序，会打印出person对象中name的值"name_1"

提醒：如果要运行在MyEcplise建立的web项目上，会出错。

因为用 MyEcplise创建web项目，会自动加入javaee.jar，这里面已经封装了javamail和activation，所以造成了冲突，只要用解压工具打开javaee.jar文件，把里面的mail和activation删了就可以正常的访问了。
