[java] WSDL 파일 읽고 자바코드 생성

2017. 5. 11. 18:42

해외 기업의 웹서비스를 이용하는 기능을 개발하고 있다. 이 과정에서 낯설은 wsdl 생성과정 및 SOAP 사용방법을 정리해보고자 한다.
wsimport 는 JAX-WS 에 적합한 산출물을 생성하는 도구다. wsdl(Web Services Description Language) 을 불러와 그 파일을 기준으로 자바 코드를 생성한다.

사용방법사용방법은 간단하다(물론 옵션은 여러가지가 있다. 상황에 따라 적절한 옵션을 추가하자).
$ wsimport {wsdl-url}
선택사항$ wsimport
wsimport
Missing WSDL_URI
 
 
Usage: wsimport [options] <WSDL_URI>
 
where [options] include:
  -b <path>                 specify jaxws/jaxb binding files or additional schemas
                            (Each <path> must have its own -b)
  -B<jaxbOption>            Pass this option to JAXB schema compiler
  -catalog <file>           specify catalog file to resolve external entity references
                            supports TR9401, XCatalog, and OASIS XML Catalog format.
  -classpath <path>         specify where to find user class files and wsimport extensions
  -cp <path>                specify where to find user class files and wsimport extensions
  -d <directory>            specify where to place generated output files
  -encoding <encoding>      specify character encoding used by source files
  -extension                allow vendor extensions - functionality not specified
                            by the specification.  Use of extensions may
                            result in applications that are not portable or
                            may not interoperate with other implementations
  -help                     display help
  -httpproxy:<proxy>        set a HTTP proxy. Format is [user[:password]@]proxyHost:proxyPort
                            (port defaults to 8080)
  -J<javacOption>           pass this option to javac
  -keep                     keep generated files
  -p <pkg>                  specifies the target package
  -quiet                    suppress wsimport output
  -s <directory>            specify where to place generated source files
  -target <version>         generate code as per the given JAXWS spec version
                            Defaults to 2.2, Accepted values are 2.0, 2.1 and 2.2
                            e.g. 2.0 will generate compliant code for JAXWS 2.0 spec
  -verbose                  output messages about what the compiler is doing
  -version                  print version information
  -fullversion              print full version information
  -wsdllocation <location>  @WebServiceClient.wsdlLocation value
  -clientjar <jarfile>      creates the jar file of the generated artifacts along with the
                            WSDL metadata required for invoking the web service.
  -generateJWS              generate stubbed JWS implementation file
  -implDestDir <directory>  specify where to generate JWS implementation file
  -implServiceName <name>   local portion of service name for generated JWS implementation
  -implPortName <name>      local portion of port name for generated JWS implementation
 
Extensions:
  -XadditionalHeaders              map headers not bound to request or response message to
                                   Java method parameters
  -Xauthfile                       file to carry authorization information in the format
                                   http://username:password@example.org/stock?wsdl
  -Xdebug                          print debug information
  -Xno-addressing-databinding      enable binding of W3C EndpointReferenceType to Java
  -Xnocompile                      do not compile generated Java files
  -XdisableAuthenticator           disable Authenticator used by JAX-WS RI,
                                   -Xauthfile option will be ignored if set
  -XdisableSSLHostnameVerification disable the SSL Hostname verification while fetching
                                   wsdls
 
Examples:
  wsimport stock.wsdl -b stock.xml -b stock.xjb
  wsimport -d generated http://example.org/stock?wsdl

실습http://www.webservicex.com/globalweather.asmx?WSDL 을 기준으로 테스트를 해보자.
$ wsimport -verbose -keep -extension http://www.webservicex.com/globalweather.asmx\?WSDL
라고 실행하면

처럼 실행되어 있는 것을 볼 수 있을 것이다. 대상으로 하는 wsdl 파일을 내려받은 후에 이파일을 기준으로 자바코드를 생성하는 과정을 확인할 수 있다. 그리고 내려받은 자바코드를 컴파일하는 것까지 처리해준다.
생성된 디렉토리의 구조는 다음과 같다.
