Apache Axis2 是Axis的后续版本,是新一代的SOAP引擎。
Axis2 JAX-WS sample that uses JAXB artifacts created from a simple schema. 1. Given a simple schema, generate the JAXB artifacts using xjc. 2. With the generated JAXB beans in hand, write the service implementation and add annotations to make a Web Service. 3. Write a Dispatch client to interact with the service 4. Run the Dispatch client against the service implementation deployed in the Axis2 server This address book sample is based on one of the jaxws-integration tests: modules/jaxws-integration/test/org/apache/axis2/jaxws/sample/addressbook Note that this is a very simple example, and does not persist any data. The intent is to illustrate the use of JAXB objects with JAX-WS, not to actually implement and address book. The following source is included with this example: src\AddressBookEntry.xsd: Schema used to generate JAXB artifacts src\org\apache\axis2\jaxws\addressbook\ JAXWS Service Endpoint Interface (SEI) Note that this SEI is NOT CURRENTLY USED in this example. src\org\apache\axis2\jaxws\addressbook\ JAXWS Dispatch Client src\org\apache\axis2\jaxws\addressbook\ JAXWS service implementation Step 0: How to build this sample ================================ To build this sample, execute the following maven command: mvn clean install This will do the following: - Generate the JAXB artifacts (in target/schema) - Compile the service implementation classes (in target/classes), including the JAXB artifacts, and create a JAR containing those classes (target/jaxws-addressbook-SNAPSHOT.jar) - Compile the Dispatch client classes (in target/classes) and create a JAR containing those classes (target/jaxws-addressbook-SNAPSHOT-Client.jar). Step 1: Generate JAXB artifacts from simple schema ================================================== The file src/AddressBookEntry.xsd describes a simple AddressBookEntry object with the following fields: String firstName; String lastName; String phone; String street; String city; String state; The following JAXB artifacts are generated in the target/schema/src directory when the sample is built org\apache\axis2\jaxws\addressbook\ org\apache\axis2\jaxws\addressbook\ org\apache\axis2\jaxws\addressbook\ These files will be compiled into target/classes as part of the build. Step 2: Write a JAX-WS service implementation using the JAXB artifacts ====================================================================== The simple service implementation will have two methods on it: public String addEntry(String firstName, String lastName, String phone, String street, String city, String state) public AddressBookEntry findByLastName(String lastName) The service implementation does not explicitly specify a JAX-WS SEI. The public methods on the implementation will be an implicit SEI. Simply by adding an @WebService annotation to the implementation class it becomes a JAX-WS web service. The implementation class is: src\org\apache\axis2\jaxws\addressbook\ This file will be compiled into target/classes as part of the build. Step 3: Write a JAX-WS Dispatch client to interact with the service =================================================================== The extremely simple Dispatch client will be a Payload mode String Dispatch client, meaning that it will provide the exact SOAP body to send in the request (Payload mode) as a String, and expect the response to be a SOAP body returned as a String. It will invoke both methods on the service implenetation's implicit SEI. The dispatch client class is: src\org\apache\axis2\jaxws\addressbook\ This file will be compiled into target/classes as part of the build. Step 4: Run the Dispatch client against the service implementation deployed in the Axis2 server =============================================================================================== (a) Setup your environment to run the sample. You will need two windows, one for the server and one for the client. Each needs the following environment variables set: - Axis2 binary distribution. For example: AXIS2_HOME=C:\temp\Axis2\axis2-SNAPSHOT - Java5 JDK. For example: JAVA_HOME=c:\java\java5 (b) Copy the service implementation JAR file from the sample target directory to the appropriate Axis2 repository directory, %AXIS2_HOME%\repository\servicejars. Note that JAR files in this directory will be deployed into the Axis2 simple server using only annotations on classes within the JARs; no deployment descriptor is required. If the repository directory does not exist, create it first, then copy the service implementation JAR: mkdir %AXIS2_HOME%\repository\servicejars copy target\jaxws-addressbook-SNAPSHOT.jar %AXIS2_HOME%\repository\servicejars (c) Start the axis2 server. This will deploy the JAX-WS service implementation. cd %AXIS2_HOME% bin\axis2server.bat You should see a message such as: [INFO] Deploying artifact : jaxws-addressbook-SNAPSHOT.jar [INFO] Deploying JAXWS annotated class org.apache.axis2.jaxws.addressbook.AddressBookImpl as a service - AddressBookImplService.AddressBookImplPort (d) From another window with the environment setup, in the jaxws-addressbook samples directory run the Dispatch client: java -Djava.ext.dirs=%AXIS2_HOME%\lib;%JAVA_HOME%\jre\lib\ext -cp target/classes org.apache.axis2.jaxws.addressbook.AddressBookClient.class You should see something like the following in the client window: >> Invoking sync Dispatch for AddEntry Add Entry response: <dlwmin:addEntryResponse xmlns:dlwmin=""><return xmlns:ns2 ="">AddEntry Completed!</return></dlwmin:addEntryResponse> >> Invoking Dispatch for findByLastName Find response: <dlwmin:findByLastNameResponse xmlns:dlwmin=""><return xmlns:ns 2=""><firstName>firstName</firstName><lastName>lastName</lastName><phone>phone< /phone><street>street</street><city>city</city><state>state</state></return></dlwmin:findByLastNameResponse>
