JDK-Tools-wsimport

wsimport是JDK自带的可以根据WSDL文档生成客户端调用代码的工具。无论服务器端WebService使用什么语言编写的,都将在客户端生成Java代码。所以服务器用什么语言编写的并不重要。


wsimport常用参数

wsimport命令语法:wsimport [options] <WSDL_URI>
注意:WSDL_URI必须含有末尾的?wsdl

常用参数:

  • -d <directory>,在指定的目录生成class文件
  • -s <directory>,在指定目录生成Java源文件
  • -p <package>,指定生成代码的包目录结构,会在生成的java代码中生成包声明语句 package <package>。-p指定的包目录会接在-s目录后面,即最终客户端代码生成的位置是:-s目录/-p目录。建议-s目录为工程src目录,-p指定完全包名,这样可以保证代码中的package包声明与实际目录一致。
  • -keep,在生成class文件,或者jar包时,同时保留java源文件
  • -clientjar <jarfile>,在当前目录生成jar文件,结合-d <directory>可以在指定的目录生成jar文件

wsimport常用参数组合

  • 在当前目录生成指定包结构的class文件和java源文件

    wsimport -s . -p com.masikkk.jws.client http://localhost:8899/HelloService?wsdl
    

    等价于:

    wsimport -keep -p com.masikkk.jws.client http://localhost:8899/HelloService?wsdl
    

    会在当前目录下生成子目录com/masikkk/jws/client/,其中有class文件和java源文件

  • 在当前目录生成指定包结构的class文件,注意不带-s参数不会生成java源文件,只有class文件

    wsimport -p com.masikkk.jws.client http://localhost:8899/HelloService?wsdl
    
  • 在指定目录生成指定包结构的class文件和java源文件
    假设wsdl文档的uri为http://localhost:6666/service/interpret?wsdl ,那么在F:\temp下,生成包结构为cn.ljl.sand.jws.chapter3.client.wsimport的java源文件的命令为:

    wsimport -s F:\temp -p cn.ljl.sand.jws.chapter3.client.wsimport
    http://localhost:6666/service/interpret?wsdl
    
  • 在指定目录生成指定包结构的jar文件
    假设wsdl文档的uri为http://localhost:6666/service/interpret?wsdl ,那么在F:\temp下,生成包结构为cn.ljl.sand.jws.chapter3.client.wsimport的interpret-wsimport.jar的命令为:

    wsimport -d F:\temp -clientjar interpret-wsimport.jar -p cn.ljl.sand.jws.chapter3.client.wsimport
    http://localhost:6666/service/interpret?wsdl
    

客户端代码核心类

根据wsdl中定义的方法个数、参数类型等不同,wsimport自动生成的java源文件个数也不同,
一般来说,每个暴露的方法会对应生成2个java类,一个定义参数、一个定义返回值。
比如,HelloService包含3个暴露的方法sayHello,sayHelloName和sayHelloList,wsimport生成的HelloService的客户端代码为:

此外,如果方法的参数或返回值中有类对象,wsimport会自动生成对应参数类或返回值类的java代码。
比如,StudentService的参数为studentRequest类,返回值为StudentResponse类,wsimport生成的StudentService的客户端代码为:

wsimport生成的java源码中,有两个是我们需要直接用到的:

  • 一个是以wsdl文档的service元素的name为名的类,HelloService中是HelloServiceImplService,通过HelloServiceImplService类的getHelloServiceImplPort()方法可以获得HelloServiceImpl类的实例,然后就可以像执行本地代码一样访问HelloServiceImpl类中的方法了。
  • 一个是以wsdl文档的portType元素的name为名的接口,本例中是HelloServiceImpl,是一个和webservice发布类同名的接口,里面包含所有发布的方法,作为调用HelloServiceImpl类的方法的本地代理。

遇到的问题

http://localhost:8080/helloService 服务发布成功,浏览器能访问到服务也可以访问到wsdl文件,使用wsimport命令生成客户端代码的时候出错。

C:\Users\MaSi>wsimport http://127.0.0.1:8080/helloService?wsdl
[ERROR] Server returned HTTP response code: 503 for URL: http://127.0.0.1:8080/helloService?wsdl
Failed to read the WSDL document: http://127.0.0.1:8080/helloService?wsdl, because 1) could not find the document; /2) the document could not be read; 3) the root element of the document is not <wsdl:definitions>.
[ERROR] failed.noservice=Could not find wsdl:service in the provided WSDL(s):
At least one WSDL with at least one service definition needs to be provided.
Failed to parse the WSDL.

原因:
1、是否设置了网络代理,如果设置了,去掉代理;
2、使用本机真实IP而不是127.0.0.1或localhost来发布webservice,例如:Endpoint.publish("http://192.168.1.123:8080/MyWebService", new TestWs());
用了两种方法都可以解决:
1、关闭公司网络代理,或将localhost加入代理“例外”中。
2、Endpoint.publish时地址修改为本机真实ip,wsimport成功。
