Use cxf to create WebService

1. Create a web project.

2,
Introduce spring and cxf packages.

3,
Create a service Terminal interface (sayhello)

Package zxf. cxf. Service; Import javax. JWS. webmethod; Import javax. JWS. WebService; @ WebService Public interface sayhello { @ Webmethod Public String say (string name ); }

4,
Create a service implementation class (sayhello)

Package zxf. cxf. Service;   Public class sayhelloimpl implements sayhello { @ Override Public String say (string name ){ System. Out. println ("Hello! "); Return "hello" + name; } }

5,
Create a configuration file (bean. XML) for the server bean)

<Beans xmlns = "http://www.springframework.org/schema/beans" Xmlns: xsi = "http://www.w3.org/2001/XMLSchema-instance" Xmlns: jaxws = "http://cxf.apache.org/jaxws" Xsi: schemalocation = "http://www.springframework.org/schema/beans Http://www.springframework.org/schema/beans/spring-beans-3.0.xsd Http://cxf.apache.org/jaxws Http://cxf.apache.org/schemas/jaxws.xsd> <! -- The following configuration is used to create the bean object required by cxf --> <Import resource = "classpath: META-INF/cxf. xml"/> <Import resource = "classpath: META-INF/cxf/cxf-extension-soap.xml"/> <Import resource = "classpath: META-INF/cxf/cxf-servlet.xml"/> <! -- Jaxws terminal --> <Jaxws: endpoint id = "helloservice" implementor = "zxf. cxf. Service. sayhelloimpl" Address = "/sayhello"/> </Beans>

6,
Configure the Web file (with spring listener and cxf servlet)

<? XML version = "1.0" encoding = "UTF-8"?> <Web-app xmlns: xsi = "http://www.w3.org/2001/XMLSchema-instance" xmlns = "http://java.sun.com/xml/ns/javaee" xmlns: Web = "http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi: schemalocation = "http://java.sun.com/xml/ns/javaee Http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd "id =" webapp_id "version =" 2.5 "> <Display-Name> cxf_service </display-Name> <Welcome-file-List> <Welcome-File> index.html </welcome-File> <Welcome-File> index.htm </welcome-File> <Welcome-File> index. jsp </welcome-File> <Welcome-File> default.html </welcome-File> <Welcome-File> default.htm </welcome-File> <Welcome-File> default. jsp </welcome-File> </Welcome-file-List> <! -- Specify the location of the spring configuration file using the preceding parameters --> <Context-param> <Param-Name> contextconfiglocation </param-Name> <Param-value> classpath: Beans. xml </param-value> </Context-param> <! -- Configure the spring context loader listener to ensure that the spring container Initialization is completed when the web server is started. --> <Listener> <Listener-class> org. springframework. Web. Context. contextloaderlistener </listener-class> </Listener> <! -- Configure the servlet of the cxf engine --> <Servlet> <Servlet-Name> cxfservlet </servlet-Name> <Servlet-class> org. Apache. cxf. Transport. servlet. cxfservlet </servlet-class> <Load-on-startup> 1 </load-on-startup> </Servlet> <Servlet-mapping> <Servlet-Name> cxfservlet </servlet-Name> <URL-pattern>/* </url-pattern> </Servlet-mapping> </Web-app>

7,
Deploy the Web service to Tomcat. View the service documentation.

8,
View the WebService Description document http: // localhost: 8080/cxf_service/helloservice? WSDL

9,
Create an exclusive program for WebService.

(1)
Introduce the class library. Cxf + spring

(2)
Create the spring configuration file clent. xml

<Beans xmlns = "http://www.springframework.org/schema/beans" Xmlns: xsi = "http://www.w3.org/2001/XMLSchema-instance" Xmlns: jaxws = "http://cxf.apache.org/jaxws" Xsi: schemalocation = "http://www.springframework.org/schema/beans Http://www.springframework.org/schema/beans/spring-beans.xsd Http://cxf.apache.org/jaxws Http://cxf.apache.org/schemas/jaxws.xsd> <Jaxws: Client ID = "sayhelloserviceclient" Serviceclass = "zxf. cxf. Service. sayhello" Address = "http: // localhost: 8080/cxf_service/helloservice"/> </Beans>

(3) copy the sayhello interface.

(4) Create an app Client

Package zxf. cxf. Service; Import org. springframework. Context. applicationcontext; Import org. springframework. Context. Support. classpathxmlapplicationcontext; Public class app { Public static void main (string [] ARGs ){ System. Out. println (system. getproperty ("Java. endorsed. dirs ")); Applicationcontext AC = new classpathxmlapplicationcontext ("client. xml "); Sayhello S = (sayhello) AC. getbean ("sayhelloserviceclient "); System. Out. println (S. Say ("dfdsf ")); } }

(5) run the app if the following error occurs:

Java. Lang. linkageerror: jaxb 2.0 API is being loaded from the bootstrap classloader, but this Ri *** needs 2.1 API.

Solution:
1. If it is an application project, print it out in the program

System. Out. println (system. getproperty ("Java. endorsed. dirs "));
Locate the appropriate location, put the jaxb-api-2.1.jar and jaxb-impl-2.1.12.jar under the corresponding directory. No endorsed directory. Create one by yourself.
2. If it is a Java Web project, print it in a project that runs like servlet:

System. Out. println (system. getproperty ("Java. endorsed. dirs "));
Locate the appropriate location, put the jaxb-api-2.1.jar and jaxb-impl-2.1.12.jar under the corresponding directory. No endorsed directory. Create one by yourself.
In my web project, the printed path is: e: \ Java \ apache-Tomcat-7.0.19 \ endorsed

The jar files placed in the endorsed directory can overwrite the system API. It can be far-fetched to put the modified API into the virtual machine, and replace it with the startup API specified by the VM.
