MULE ESB webservice jms服务
写之前的内容时,Mule刚刚3.0.1版本,很多官方文档还没有更新(尤其示例代码),维持在V2的状态。经过了一年多的时间,Mule社区版发展至了3.2版本,并且推出了Mule Studio可视化开发工具(当前beta状态,支持Mule 3.1.2)。 将以前自己验证的示例代码在3.1.2版本上又跑了一遍(有些变化),在此做一下记录。 一. 服务调用 1. Mule实现并提供Web Service ? ? 在Mule上开发并发布一个Web Service供客户端调用。
<flow name="local-ws"> ??? <core:inbound-endpoint address="http://localhost:65082/services/Echo1" ??????? exchange-pattern="request-response" doc:name="Generic" doc:description="Generic endpoint specified by address URI" /> ??? <cxf:jaxws-service serviceClass="demo.mule.component.Echo" doc:name="SOAP" ??????? doc:description="Make a web service available via CXF" /> ??? <component doc:name="Component" doc:description="Invoke a Java component"> ??????? <singleton-object class="demo.mule.component.Echo" /> ??? </component> </ flow >
2. Web Service Proxy ? ? Web Service Proxy用来将客户端的WS请求直接转发至相应的远程WS服务端处理,并返回处理结果。Mule本身不做任何处理。 2.1 配置方式1
<flow name="local2remote-ws"> ??? <http:inbound-endpoint keep-alive="false" address="http://localhost:65000" ??????? encoding="UTF-8" disableTransportTransformer="false" exchange-pattern="request-response" doc:name="HTTP" ??????? doc:description="" /> ??? <http:outbound-endpoint method="GET" keep-alive="false" ??????? address="http://localhost:5050#[header:INBOUND:http.request]" responseTimeout="10000" encoding="UTF-8" ??????? disableTransportTransformer="false" followRedirects="false" exchange-pattern="request-response" ??????? doc:name="HTTP" doc:description="" /> </ flow >
2.2 配置方式2
<pattern:web-service-proxy name="ws-proxy" inboundAddress="http://localhost:65082/services/Echo2" ??? outboundAddress="http://localhost:65082/services/Echo1?method=echo"> </pattern:web-service-proxy>
3. Web Service to Web Service ? ? Web Service To Web Service用于在Mule中提供Web Service供客户端调用,Mule接收请求后调用远端的Web Service进行处理,并返回结果。
<flow name="local-ws2remote-ws"> ??? <core:inbound-endpoint address="http://localhost:65082/services/Echo8" ??????? disableTransportTransformer="false" exchange-pattern="request-response" doc:name="Generic" ??????? doc:description="Generic endpoint specified by address URI" /> ??? <cxf:jaxws-service serviceClass="demo.mule.component.Echo" doc:name="SOAP" ??????? doc:description="Make a web service available via CXF" /> ??? <core:outbound-endpoint ??????? address="wsdl-cxf:http://server1:5050/mule-business/webservice/EchoService?wsdl&method=Echo" /> </ flow >
4. Socket to Socket ? ? Socket To Socket用于将客户端的Socket请求转发至远程的Socket服务端处理,并返回处理结果。
<flow name="tcp2tcp"> ??? <tcp:inbound-endpoint host="localhost" port="7100" responseTimeout="10000" ??????? encoding="UTF-8" disableTransportTransformer="false" exchange-pattern="request-response" doc:name="TCP" ??????? doc:description="The TCP transport enables events to be sent and received over TCP sockets." /> ??? <tcp:outbound-endpoint host="localhost" port="7000" responseTimeout="10000" ??????? encoding="UTF-8" disableTransportTransformer="false" exchange-pattern="request-response" doc:name="TCP" ??????? doc:description="The TCP transport enables events to be sent and received over TCP sockets." /> </ flow >
5. JMS Topic ? ? 客户端发送Web Service请求,Mule将请求消息发送至远程JMS的Topic中。
<flow name="local-ws2jms-topic"> ??? <core:inbound-endpoint address="http://localhost:65082/services/Echo3" ??????? responseTimeout="10000" encoding="UTF-8" disableTransportTransformer="false" mimeType="text/plain" ??????? exchange-pattern="one-way" doc:name="Generic" doc:description="Generic endpoint specified by address URI" /> ??? <cxf:jaxws-service serviceClass="demo.mule.component.Echo" doc:name="SOAP" ??????? doc:description="Make a web service available via CXF" /> ??? <jms:outbound-endpoint topic="topic1" responseTimeout="10000" encoding="UTF-8" ??????? disableTransportTransformer="false" disableTemporaryReplyToDestinations="false" exchange-pattern="one-way" ??????? connector-ref="activemqConnector" doc:name="JMS" doc:description="Send or receive messages from a JMS queue" /> </flow> <flow name="jms-topic2echo"> ??? <jms:inbound-endpoint topic="topic1" responseTimeout="10000" encoding="UTF-8" ??????? disableTransportTransformer="false" disableTemporaryReplyToDestinations="false" exchange-pattern="one-way" ??????? connector-ref="activemqConnector" doc:name="JMS" doc:description="Send or receive messages from a JMS queue" /> ??? <echo-component doc:name="Echo" doc:description="Echoes message payload." /> </ flow >
二. 基于消息内容的路由 ? ? Mule提供基于消息内容的路由机制,根据消息中的指定信息,将消息发送至不同的服务端进行处理。 1. Socket to Socket 路由
<flow name="tcp2tcp-router"> ??? <tcp:inbound-endpoint host="localhost" port="7101" responseTimeout="10000" ??????? encoding="UTF-8" disableTransportTransformer="false" exchange-pattern="request-response" doc:name="TCP" ??????? doc:description="The TCP transport enables events to be sent and received over TCP sockets." /> ??? <choice> ??????? <when evaluator="jxpath" expression="(req/area)='bj'"> ??????????? <tcp:outbound-endpoint host="server1" port="7101" ??????????????? responseTimeout="10000" encoding="UTF-8" disableTransportTransformer="false" exchange-pattern="request-response" ??????????????? doc:name="TCP" doc:description="The TCP transport enables events to be sent and received over TCP sockets." /> ??????? </when> ??????? <when evaluator="jxpath" expression="(req/area)='sh'"> ??????????? <tcp:outbound-endpoint host="server1" port="7102" ??????????????? responseTimeout="10000" encoding="UTF-8" disableTransportTransformer="false" exchange-pattern="request-response" ??????????????? doc:name="TCP" doc:description="The TCP transport enables events to be sent and received over TCP sockets." /> ??????? </when> ??? </choice> </ flow >
2. Web Service to JMS Topic 路由
<flow name="local-ws2jms-topic-router"> ??? <core:inbound-endpoint address="http://localhost:65082/services/Echo7" ??????? disableTransportTransformer="false" exchange-pattern="request-response" doc:name="Generic" ??????? doc:description="Generic endpoint specified by address URI" /> ??? <cxf:jaxws-service serviceClass="demo.mule.component.Echo" doc:name="SOAP" ??????? doc:description="Make a web service available via CXF" /> ??? <choice> ??????? <when evaluator="jxpath" expression="(req/area)='bj'"> ??????????? <jms:outbound-endpoint topic="topic1" responseTimeout="10000" encoding="UTF-8" ??????????????? disableTransportTransformer="false" disableTemporaryReplyToDestinations="false" ??????????????? exchange-pattern="one-way" connector-ref="activemqConnector" doc:name="JMS" ??????????????? doc:description="Send or receive messages from a JMS queue" /> ??????? </when> ??????? <when evaluator="jxpath" expression="(req/area)='sh'"> ??????????? <jms:outbound-endpoint topic="topic2" responseTimeout="10000" encoding="UTF-8" ??????????????? disableTransportTransformer="false" disableTemporaryReplyToDestinations="false" ??????????????? exchange-pattern="one-way" connector-ref="activemqConnector" doc:name="JMS" ??????????????? doc:description="Send or receive messages from a JMS queue" /> ??????? </when> ??? </choice> </ flow >
3. Web Service to Web Service 路由
<flow name="local-ws2jms-topic-router"> ????<core:inbound-endpoint address="http://localhost:65082/services/Echo9" ????????disableTransportTransformer="false" exchange-pattern="request-response" doc:name="Generic" ????????doc:description="Generic endpoint specified by address URI" /> ????<cxf:jaxws-service serviceClass="demo.mule.component.Echo" doc:name="SOAP" ????????doc:description="Make a web service available via CXF" /> ????<choice> ????????<when evaluator="jxpath" expression="(req/area)='bj'"> ????????????<core:outbound-endpoint ??????????????? address="wsdl-cxf:http://server1:5050/mule-business/webservice/CalcService?wsdl&method=processXml" /> ????????</when> ????????<when evaluator="jxpath" expression="(req/area)='sh'"> ????????????<core:outbound-endpoint ????????????????address="wsdl-cxf:http://server2:5050/mule-business/webservice/CalcService?wsdl&method=processXml" /> ????????</when> ????</choice> </ flow >
三. 数据转换 1. 压缩解压 ? ? Mule原生提供了gzip压缩方式的Transformer。
<flow name="gzip"> ????<stdio:inbound-endpoint ref="stdioInEndpoint" /> ????<core:string-to-byte-array-transformer encoding="UTF-8" /> ????<component class="demo.mule.component.Passthrough" /> ????<core:gzip-compress-transformer encoding="UTF-8" /> ????<component class="demo.mule.component.Passthrough"?/> ????<core:gzip-uncompress-transformer encoding="UTF-8" /> ????<component class="demo.mule.component.Passthrough" /> ????<core:byte-array-to-string-transformer encoding="UTF-8" /> ????<stdio:outbound-endpoint ref="stdioOutEndpoint" /> </ flow >
2. 加密解密 ? ? 加密、解密是一种特定的数据转换方式,因此通过自定义Transformer的形式支持。
<flow name="encrypt"> ????<core:inbound-endpoint address="http://localhost:65082/services/Echo11" ????????responseTimeout="10000" encoding="UTF-8" disableTransportTransformer="false" mimeType="text/plain" ????????exchange-pattern="one-way" /> ????<cxf:jaxws-service serviceClass="demo.mule.component.Echo" /> ????<component> ????????<singleton-object class="demo.mule.component.Echo" /> ????</component> ????<core:custom-transformer class="demo.mule.transformer.DesEncryptTransformer" encoding="UTF-8" /> ????<component class="demo.mule.component.Passthrough" /> ????<core:custom-transformer class="demo.mule.transformer.DesDecryptTransformer" encoding="UTF-8" /> ????<stdio:outbound-endpoint ref="stdioOutEndpoint" /> </ flow >
3. 自定义Transformer
import demo.mule.dto.Envelope; ? publicclassString2EnvelopeTransformerextendsAbstractTransformer{ ??? privatestaticLoglog=LogFactory.getLog(String2EnvelopeTransformer.class); ? ??? @Override ??? protectedObjectdoTransform(Objectsrc,Stringenc)throws TransformerException { ??????? Envelopeenv=newEnvelope(); ??????? if(srcinstanceofString){ ??????????? StringTokenizerst=newStringTokenizer((String)src,","); ??????????? Stringarea=st.nextToken(); ??????????? Stringdata=st.nextToken(); ??????????? env.create(area,data); ??????? } ??????? log.debug(env); ??????? returnenv; ??? } }
<flow name="local-ws"> ????<core:inbound-endpoint address="http://localhost:65082/services/Echo1" ????????exchange-pattern="request-response" doc:name="Generic" doc:description="Generic endpoint specified by address URI" /> ????<cxf:jaxws-service serviceClass="demo.mule.component.Echo" doc:name="SOAP" ????????doc:description="Make a web service available via CXF" /> ????<component doc:name="Component" doc:description="Invoke a Java component"> ????????<singleton-object class="demo.mule.component.Echo" /> ????</component> ????<core:custom-transformer class="demo.mule.transformer.String2EnvelopeTransformer"></core:custom-transformer> ????<core:outbound-endpoint address="stdio://System.out" exchange-pattern="one-way" /> </ flow >
仅以上述示例代码作为这一段时间Mule文档阅读及试用的总结。 PS:程序代码插件有时有点问题,前几段代码字体是CN,后边就突然变成一种非等宽字体了。而且XML的格式不是很直观,因此直接粘贴了。。 (编辑:李大同) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
