WebService-Axis2的方式
1、引入相关的依赖：
<properties><project.build.sourceEncoding>UTF-8</project.build.sourceEncoding><maven.compiler.source>1.8</maven.compiler.source><maven.compiler.target>1.8</maven.compiler.target><axis2.version>1.7.9</axis2.version></properties><dependencies><dependency><groupId>junit</groupId><artifactId>junit</artifactId><version>4.11</version><scope>test</scope></dependency><!--axis2 begin--><dependency><groupId>org.apache.axis2</groupId><artifactId>axis2</artifactId><version>${axis2.version}</version><type>pom</type></dependency><dependency><groupId>org.apache.axis2</groupId><artifactId>axis2-spring</artifactId><version>${axis2.version}</version><exclusions><exclusion><groupId>org.springframework</groupId><artifactId>spring-beans</artifactId></exclusion><exclusion><groupId>org.springframework</groupId><artifactId>spring-core</artifactId></exclusion><exclusion><groupId>org.springframework</groupId><artifactId>spring-web</artifactId></exclusion><exclusion><groupId>org.springframework</groupId><artifactId>spring-context</artifactId></exclusion></exclusions></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-context</artifactId><version>4.3.18.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-web</artifactId><version>4.3.18.RELEASE</version></dependency><dependency><groupId>org.apache.axis2</groupId><artifactId>axis2-transport-http</artifactId><version>${axis2.version}</version></dependency><dependency><groupId>org.apache.axis2</groupId><artifactId>axis2-transport-local</artifactId><version>${axis2.version}</version></dependency><dependency><groupId>org.apache.axis2</groupId><artifactId>axis2-xmlbeans</artifactId><version>${axis2.version}</version></dependency></dependencies><build><finalName>axis2-demo</finalName><pluginManagement><!-- lock down plugins versions to avoid using Maven defaults (may be moved to parent pom) --><plugins><plugin><artifactId>maven-clean-plugin</artifactId><version>3.1.0</version></plugin><!-- see http://maven.apache.org/ref/current/maven-core/default-bindings.html#Plugin_bindings_for_war_packaging --><plugin><artifactId>maven-resources-plugin</artifactId><version>3.0.2</version></plugin><plugin><artifactId>maven-compiler-plugin</artifactId><version>3.8.0</version></plugin><plugin><artifactId>maven-surefire-plugin</artifactId><version>2.22.1</version></plugin><plugin><artifactId>maven-war-plugin</artifactId><version>3.2.2</version></plugin><plugin><artifactId>maven-install-plugin</artifactId><version>2.5.2</version></plugin><plugin><artifactId>maven-deploy-plugin</artifactId><version>2.8.2</version></plugin></plugins></pluginManagement></build></project>
1.1、spring整合axis2的配置
1.2、把交给spring容器管理的对象让axis2去访问它。
2.2、新建个services.xml的文件：
内容如下：
<?xml version="1.0" encoding="UTF-8"?><!-- 通过ServiceObjectSupplier参数指定SpringServletContextObjectSupplier类来获得Spring的ApplicationContext对象 --><!--访问的终端名称--><service name="ServiceServer"><description>axis2</description><!-- 通过ServiceObjectSupplier参数指定SpringServletContextObjectSupplier类来获得Spring的ApplicationContext对象 --><parameter name="ServiceObjectSupplier" locked="false">org.apache.axis2.extensions.spring.receivers.SpringServletContextObjectSupplier</parameter><!--SpringBeanName固定的不能改userServiceImpl是spring中注册的实现类得id,@Component注解--><parameter name="SpringBeanName">userService</parameter><!--<messageReceivers>元素，该元素用于设置处理WebService方法的处理器。例如，hello方法有一个返回值，因此，需要使用可处理输入输出的RPCMessageReceiver类，而update方法没有返回值，因此，需要使用只能处理输入的RPCInOnlyMessageReceiver类。--><messageReceivers><messageReceiver mep="http://www.w3.org/2004/08/wsdl/in-only"class="org.apache.axis2.rpc.receivers.RPCInOnlyMessageReceiver"/><messageReceiver mep="http://www.w3.org/2004/08/wsdl/in-out"class="org.apache.axis2.rpc.receivers.RPCMessageReceiver"/></messageReceivers></service>
1.3，新建个web.xml文件，内容如下：
1.4、提供暴漏出的接口以及对应的实现类，代码如下：
package com.ws.axis2.service;import com.ws.axis2.domain.User;public interface UserService {User add(User user);User get(Integer userId);}package com.ws.axis2.service;import com.ws.axis2.domain.User;import org.springframework.stereotype.Service;@Service("userService")public class UserServiceImpl implements UserService {@Overridepublic User add(User user) {user.setUserName(user.getUserName());return user;}@Overridepublic User get(Integer userId) {User user =new User();user.setUserId(userId);user.setUserName("魏朝阳");return user;}}
1.5、User的实体类如下：
package com.ws.axis2.domain;public class User {private Integer userId;private String userName;public Integer getUserId() {return userId;}public void setUserId(Integer userId) {this.userId = userId;}public String getUserName() {return userName;}public void setUserName(String userName) {this.userName = userName;}}
1.6、去访问相应的wsdl文件如下：这时的参数类型是User.这里如果用原生的WebSrvice会报错误的。
访问下get方法：下面的结果就能证明，webService就是通过xml来定义格式的。
2、如何去在客户端做调用呢？
①、先生成客户端调用的类，拷贝到项目中的位置，先去apache Axis2的官网去下载axis2的文件
②、使用wsdl2java的批处理文件。命令如下：
wsdl2java -uri http://localhost:8080/services/ServiceServer?wsdl -p client -s -o stub
-url参数指定了wsdl文件的路径，可以是本地路径，也可以是网络路径。-p参数指定了生成的Java类的包名，
-o参数指定了生成的一系列文件保存的根目录。
-s 同步模式代码
-a 异步模式代码
③、将生成的客户端代码类拷贝到客户端测试调用
④、客户端的主函数的代码如下：
package org.example;import client.ServiceServerStub;import org.apache.axis2.AxisFault;import java.rmi.RemoteException;public class App {public static void main( String[] args ) {try {ServiceServerStub serviceServerStub=new ServiceServerStub();ServiceServerStub.Get get = new ServiceServerStub.Get();get.setUserId(1003);try {ServiceServerStub.GetResponse response=serviceServerStub.get(get);ServiceServerStub.User user = response.get_return();System.out.println(user.getUserName()+","+user.getUserId());} catch (RemoteException e) {e.printStackTrace();}} catch (AxisFault axisFault) {axisFault.printStackTrace();}}}
运行的结果如下：
上面的过程就是客户端调用服务端的接口，从而返回相应的结果。
