下载axis的war包下载地址
将下载好的war包部署到tomcat
使用方法
1. 第一种
  1. 创建一个java类
```
public class SimpleService
{
    public String getGreeting(String name)
    {
        System.out.println(name);
        return "hello===== " + name;
    }    
    public int getPrice()
    {
        return new java.util.Random().nextInt(1000);
    }    
}
```
  1. 编译java类,将编译好的class文件放在apache-tomcat-8.5.58webappsaxis2WEB-INFpojo下,pojo文件夹没有就创建
  2. 修改或添加默认的pojo文件夹-->apache-tomcat-8.5.58webappsaxis2WEB-INFconf--><deployer extension=".class" directory="pojo" class="org.apache.axis2.deployment.POJODeployer"/>
  3. 修改热部署或热更新
    <parameter name="hotdeployment">true</parameter>`` <parameter name="hotupdate">true</parameter>
2. 第二种
  1. 创建一个基本的maven项目,添加依赖
org.apache.axis2 axis2-adb 1.7.9 ``` 2. 在resource下创建文件夹`META-INF`,在该文件夹创建services.xml内容参考 ```xml <--多个使用serviceGroup在外面包围--> 测试 cn.jaminye.HelloWorld ```

import javax.jws.WebParam;

   /**
    * 测试
    *
       * @author Jamin
       * @date 2021/1/5 9:05
       */
      public class HelloWorld {
   	/**
   	 * 无返回值
			 *
			 * @param message
			 * @author Jamin
			 * @date 2021/1/5 9:16
			 */
			public void testHello(@WebParam String message) {
				System.out.println(message);
			}
		
		
			/**
			 * 有返回值
			 *
			 * @param x
			 * @param y
			 * @return {@link int}
			 * @author Jamin
			 * @date 2021/1/5 9:15
			 */
			public int plus(@WebParam int x, @WebParam int y) {
				return x + y;
			}
		}

	3. 将项目打成jar包放在`apache-tomcat-8.5.58webappsaxis2WEB-INFservices`

启动tomcat,打开http://localhost:8080/axis2/services/listServices查看所有服务
点击查看该服务的wsdl文件说明书
输入http://localhost:8080/axis2/services/HelloWorld/plus?x=1&y=2查看返回的xml数据

代码调用

第一种rpc调用

// 使用rpc的方式调用   无返回值
Options options1 = rpcServiceClient.getOptions();
//地址
options1.setTo(new EndpointReference("http://localhost:8080/axis2/services/HelloWorld/testHello"));
//参数
Object[] inArgs1 = {"测试"};
//命名空间
QName qName1 = new QName("http://jaminye.cn", "testHello");
rpcServiceClient.invokeRobust(qName1, inArgs1);

//使用rpc的方式调用    有返回值
RPCServiceClient rpcServiceClient = new RPCServiceClient();
Options options = rpcServiceClient.getOptions();
//指定调用地址
options.setTo(new EndpointReference("http://localhost:8080/axis2/services/HelloWorld"));
//指定入参与出参类型
Object[] inArgs = {1, 2};
Class[] classes = {String.class};
QName qName = new QName("http://jaminye.cn", "plus");
System.out.println(rpcServiceClient.invokeBlocking(qName, inArgs, classes)[0]);

第二种根据入参

//无返回值调用
ServiceClient serviceClient = new ServiceClient();
Options options = serviceClient.getOptions();
options.setTo(new EndpointReference("http://localhost:8080/axis2/services/HelloWorld"));
options.setAction("http://jaminye.cn/HelloWorld");
OMFactory omFactory = OMAbstractFactory.getOMFactory();
OMNamespace omNamespace = omFactory.createOMNamespace("http://jaminye.cn", "");
OMElement method = omFactory.createOMElement("testHello", omNamespace);
OMElement paramsName = omFactory.createOMElement("message", omNamespace);
paramsName.setText("测试");
method.addChild(paramsName);
method.build();
serviceClient.sendRobust(method);
//有返回值调用
ServiceClient serviceClient = new ServiceClient();
Options options = serviceClient.getOptions();
options.setTo(new EndpointReference("http://localhost:8080/axis2/services/HelloWorld"));
options.setAction("http://jaminye.cn/HelloWorld");
OMFactory omFactory = OMAbstractFactory.getOMFactory();
OMNamespace omNamespace = omFactory.createOMNamespace("http://jaminye.cn", "");
OMElement method = omFactory.createOMElement("plus", omNamespace);
OMElement paramsX = omFactory.createOMElement("x", omNamespace);
paramsX.setText("1");
OMElement paramsY = omFactory.createOMElement("y", omNamespace);
paramsY.setText("2");
method.addChild(paramsX);
method.addChild(paramsY);
method.build();
OMElement result = serviceClient.sendReceive(method);
//返回原来的xml
System.out.println(result);
//获取真正的返回值
System.out.println(result.getFirstElement().getText());

复合数据类型

/**
	 * 上传字节
	 *
	 * @param imageByte
	 * @return {@link boolean}
	 * @author Jamin
	 * @date 2021/1/14 9:33
	 */
	public boolean uploadImageWithByte(byte[] imageByte) {
		FileOutputStream fileOutputStream = null;
		try {
			fileOutputStream = new FileOutputStream("d:\1.jpeg");
			fileOutputStream.write(imageByte, 0, imageByte.length);
		} catch (IOException e) {
			e.printStackTrace();
			return false;
		} finally {
			if (fileOutputStream != null) {
				try {
					fileOutputStream.close();
				} catch (IOException e) {
					e.printStackTrace();
					return false;
				}
			}
		}

		return false;
	}

	/**
	 * 无参返回数组
	 *
	 * @param
	 * @return {@link String[]}
	 * @author Jamin
	 * @date 2021/1/19 15:46
	 */
	public String[] returnArray() {
		String[] strings = {"1", "2", "3", "4"};
		return strings;
	}

	/**
	 * 返回一个对象
	 *
	 * @param
	 * @return {@link cn.jaminye.HelloWorld.Person}
	 * @author Jamin
	 * @date 2021/1/19 15:49
	 */
	public Person returnPerson() {
		return new Person("1", "测试", "13");
	}

	/**
	 * 返回对象字节数组
	 *
	 * @param
	 * @return {@link byte[]}
	 * @author Jamin
	 * @date 2021/1/19 15:56
	 */
	public byte[] returnBytes() throws IOException {
		ByteArrayOutputStream bos = new ByteArrayOutputStream();
		ObjectOutputStream oos = new ObjectOutputStream(bos);
		Person person = new Person("1", "测试", "13");
		oos.writeObject(person);
		return bos.toByteArray();
	}

	public class Person  implements Serializable{
		/**
		 * id
		 */
		private String id;
		/**
		 * name
		 */
		private String name;
		/**
		 * age
		 */
		private String age;

		public Person(String id, String name, String age) {
			this.id = id;
			this.name = name;
			this.age = age;
		}

		public String getId() {
			return id;
		}

		public void setId(String id) {
			this.id = id;
		}

		public String getName() {
			return name;
		}

		public void setName(String name) {
			this.name = name;
		}

		public String getAge() {
			return age;
		}

		public void setAge(String age) {
			this.age = age;
		}
	}

org.apache.axis2.AxisFault: cn.jaminye.Person

}
```

作用域详细信息
1. request 请求域
2. soapsession
3. TransportSession 会话域不加managesession 和request差不多加上和TransportSession
4. Application 应用域

获取与保存当前作用域信息

MessageContext messageContext=MessageContext.getCurrentMessageContext();         ServiceContext sc = messageContext.getServiceContext(); 
//保存值
Object previousValue = sc.setProperty("VALUE");
//获取值
Object previousValue = sc.getProperty("VALUE");

跨服务获取信息
1. 将值保存在ServiceGroupContext/ServiceContext
2. 作用域改为application
3. 调用ServiceContext需要开启session管理

异步调用

rpcServiceClient = new RPCServiceClient();
	Options options = rpcServiceClient.getOptions();
	options.setTo(new EndpointReference("http://localhost:8080/axis2/services/HelloWorld"));
	options.setManageSession(true);
	QName qName = new QName("http://jaminye.cn", "asynchronousCall");
	//异步调用
	rpcServiceClient.invokeNonBlocking(qName, new Object[]{}, new AxisCallback() {
		//异步处理
		@Override
		public void onMessage(MessageContext msgContext) {

System.out.println(msgContext.getEnvelope().getBody().getFirstElement().getFirstElement().getText());
}
@Override
public void onFault(MessageContext msgContext) {
System.out.println("onFault");
}
@Override
public void onError(Exception e) {
System.out.println(e);
}
@Override
public void onComplete() {
}
});
System.out.println("结束==========>");
System.in.read();
```

自定义模块 LoggingModule

编写module类实现org.apache.axis2.modules.Module接口
主要方法为init方法

public class LoggingModule implements Module {
@Override
public void init(ConfigurationContext configContext, AxisModule module) throws AxisFault {
	System.out.println("======================>init");
}

@Override
public void engageNotify(AxisDescription axisDescription) throws AxisFault {

}

@Override
public boolean canSupportAssertion(Assertion assertion) {
	return false;
}

@Override
public void applyPolicy(Policy policy, AxisDescription axisDescription) throws AxisFault {

}

@Override
public void shutdown(ConfigurationContext configurationContext) throws AxisFault {
	System.out.println("=========================shutdown");
}

}
2. 编写LogHandler类继承org.apache.axis2.handlers.AbstractHandler 实现org.apache.axis2.engine.Handler java
public class LogHandler extends AbstractHandler implements Handler {
private static Log log = LogFactory.getLog(LogHandler.class);

@Override
public InvocationResponse invoke(MessageContext msgContext) throws AxisFault {
	log.info("returnMsg====================>{}" + msgContext.getEnvelope().toString());
	return InvocationResponse.CONTINUE;
}

}
3. 在resource创建module.xml xml

<OutFaultFlow>
    <handler name="FaultOutFlowLogHandler" class="cn.jaminye.util.LogHandler">
        <order phase="loggingPhase"/>
    </handler>
</OutFaultFlow>
<InFaultFlow>
    <handler name="FaultInFlowLogHandler" class="cn.jaminye.util.LogHandler">
        <order phase="loggingPhase"/>
    </handler>
</InFaultFlow>

``` 4. 带依赖打包,改为mar结尾,放在axis2WEB-INFmodules目录下 5. webappsaxis2WEB-INFconf下axis2.xml [InFlow,OutFlow,InFaultFlow,OutFaultFlow] 末尾加上`` 6. 需要使用的服务中添加
