初识Axis1就要把它集成到Spring框架上。一方面是当时的项目要求,在一方面更是我对于Spring情有独钟。
Axis1+Spring比较简单,这种便利得益于Spring的ServletEndpointSupport类支持。

我们将用到以下Jar:
引用
activation.jar
axis.jar
commons-discovery.jar
commons-logging.jar
jaxrpc.jar
log4j-1.2.15.jar
mail.jar
wsdl4j.jar
spring.jar
主要就是加入了spring.jar包!
再看看web.xml,加入了Spring的相关内容。大家都熟悉Spring,我就不废话了!

我们定义一个用于计算的CalcService接口及其实现CalcServiceImpl,如下:
/**
* 简单计算
*
* @author 梁栋
* @version 1.0
* @since 1.0
*/
public interface CalcService {
/**
* 求和
*
* @param a
* @param b
* @return
*/
int add(int a, int b);
}
给出对应的实现内容:
import org.zlex.axis.service.CalcService;
/**
* 计算
*
* @author 梁栋
* @version 1.0
* @since 1.0
*/
public class CalcServiceImpl implements CalcService {
@Override
public int add(int a, int b) {
return a + b;
}
}
再简单不过的1+1问题!
将其注入到Spring的容器中,applicationContext.xml如下所示:
<?xml version="1.0" encoding="UTF-8"?>
<beans
xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">
<bean
id="calcService"
class="org.zlex.axis.service.impl.CalcServiceImpl" />
</beans>
作为spring与axis1对接,需要做一个ServletEndpointSupport继承实现WebService,如下所示:
import javax.xml.rpc.ServiceException;
import org.springframework.context.ApplicationContext;
import org.springframework.remoting.jaxrpc.ServletEndpointSupport;
import org.zlex.axis.service.CalcService;
/**
* WebService入口
*
* @author 梁栋
* @version 1.0
* @since 1.0
*/
public class WebService extends ServletEndpointSupport {
private ApplicationContext applicationContext;
private CalcService calcService;
/*
* (non-Javadoc)
*
* @see org.springframework.remoting.jaxrpc.ServletEndpointSupport#onInit()
*/
@Override
protected void onInit() throws ServiceException {
// 初始化Spirng 配置
applicationContext = super.getApplicationContext();
calcService = (CalcService) applicationContext.getBean("calcService");
}
/**
* 求和
*
* @param a
* @param b
* @return
*/
public String add(int a, int b) {
return String.valueOf(calcService.add(a, b));
}
}
这里为了便于在eclipse演示,将返回值定为String类型!
现在我们将该服务植入Axis中,修改server-config.wsdd文件,在原文件中加入如下内容:
<!-- 自定义服务 -->
<service
name="WebService"
provider="java:RPC">
<parameter
name="className"
value="org.zlex.axis.WebService" />
</service>
修改后的server-config.wsdd文件如下所示:
<?xml version="1.0" encoding="UTF-8"?>
<deployment
xmlns="http://xml.apache.org/axis/wsdd/"
xmlns:java="http://xml.apache.org/axis/wsdd/providers/java">
<globalConfiguration>
<parameter
name="adminPassword"
value="admin" />
<parameter
name="sendXsiTypes"
value="true" />
<parameter
name="sendMultiRefs"
value="true" />
<parameter
name="sendXMLDeclaration"
value="true" />
<parameter
name="axis.sendMinimizedElements"
value="true" />
<requestFlow>
<handler
type="java:org.apache.axis.handlers.JWSHandler">
<parameter
name="scope"
value="session" />
</handler>
<handler
type="java:org.apache.axis.handlers.JWSHandler">
<parameter
name="scope"
value="request" />
<parameter
name="extension"
value=".jwr" />
</handler>
</requestFlow>
</globalConfiguration>
<handler
name="Authenticate"
type="java:org.apache.axis.handlers.SimpleAuthenticationHandler" />
<handler
name="LocalResponder"
type="java:org.apache.axis.transport.local.LocalResponder" />
<handler
name="URLMapper"
type="java:org.apache.axis.handlers.http.URLMapper" />
<service
name="AdminService"
provider="java:MSG">
<parameter
name="allowedMethods"
value="AdminService" />
<parameter
name="enableRemoteAdmin"
value="false" />
<parameter
name="className"
value="org.apache.axis.utils.Admin" />
<namespace>http://xml.apache.org/axis/wsdd/</namespace>
</service>
<service
name="Version"
provider="java:RPC">
<parameter
name="allowedMethods"
value="getVersion" />
<parameter
name="className"
value="org.apache.axis.Version" />
</service>
<transport
name="http">
<requestFlow>
<handler
type="URLMapper" />
<handler
type="java:org.apache.axis.handlers.http.HTTPAuthHandler" />
</requestFlow>
</transport>
<transport
name="local">
<responseFlow>
<handler
type="LocalResponder" />
</responseFlow>
</transport>
<!-- 自定义服务 -->
<service
name="WebService"
provider="java:RPC">
<parameter
name="className"
value="org.zlex.axis.WebService" />
</service>
</deployment>
我们随机抽取2个数进行求和运算,并验证WebService和本地计算结果是否一致,测试用例WebServiceTest如下:
/**
* WebService测试
*
* @author 梁栋
* @version 1.0
* @since 1.0
*/
public class WebServiceTest {
private String nameSpaceUri = "http://localhost:8080/axis/services/WebService";
private String wsdlUrl = nameSpaceUri + "?wsdl";
private Service service;
private Call call;
@Before
public final void init() throws Exception {
// 创建调用对象
service = new Service();
call = (Call) service.createCall();
// 调用 远程方法
call.setOperationName(new QName(nameSpaceUri, "add"));
// 设置URL
call.setTargetEndpointAddress(new URL(wsdlUrl));
}
@Test
public final void testAdd() throws Exception {
// 设置参数
Random rnd = new Random();
int a = rnd.nextInt(100);
int b = rnd.nextInt(100);
// 执行远程调用,同时获得返回值
String r = (String) call.invoke(new Object[] { a, b });
assertEquals(String.valueOf(a + b), r);
System.out.println("a(" + a + ") + b(" + b + ") = " + r);
}
}
我们验证一下结果!
顺利通过!
我们在通过Eclipse验证一下这个服务!
Eclipse中输入参数验证WebService,如果要看到返回值就需要把返回值定为String类型。如果用int类型,我们只能通过测试用例检测这个结果!
