Spring-WS：如何在不启动Web服务的情况下生成WSDL？

Question

我们使用Spring-WS作为实现Web服务的基础（使用框架生成的WSDL）。除了WAR文件，我们的构建还生成客户端JAR（供我们的Java客户端和我们自己的端到端功能测试使用），包括模式生成的DTO和Web服务方法的存根。这些是使用wsimport（JAX-WS）生成的。问题是这引起了多步骤构建过程：

1. 构建服务器WAR文件;
2. 启动Tomcat（使WSDL可用）;
3. 生成客户端存根（将wsimport指向WSDL url）。

有什么方法可以在不启动Web服务的情况下生成WSDL吗？然后，我们可以在一个步骤中建立一切。

此示例代码是适合于Ant任务的基础：

import javax.xml.stream.XMLStreamException; 
import javax.xml.transform.TransformerFactory; 

import org.springframework.core.io.FileSystemResource; 
import org.springframework.core.io.Resource; 
import org.springframework.ws.wsdl.wsdl11.DefaultWsdl11Definition; 
import org.springframework.xml.transform.StringResult; 
import org.springframework.xml.transform.StringSource; 
import org.springframework.xml.xsd.commons.CommonsXsdSchemaCollection; 

.... 

private String generateWsdlFromSpringInfrastructure() throws Exception 
{ 
    // We only need to specify the top-level XSD 
    FileSystemResource messagesXsdResource = new FileSystemResource("C:/MyProject/xsds/my-messages.xsd"); 
    CommonsXsdSchemaCollection schemaCollection = new CommonsXsdSchemaCollection(new Resource[] {messagesXsdResource}); 
    // In-line all the included schemas into the including schema 
    schemaCollection.setInline(true); 
    schemaCollection.afterPropertiesSet(); 

    DefaultWsdl11Definition definition = new DefaultWsdl11Definition(); 
    definition.setSchemaCollection(schemaCollection); 
    definition.setPortTypeName(portTypeName); 
    definition.setLocationUri("http://localhost:8080/myProject/services"); 
    definition.setTargetNamespace("http://www.acme.com/my-project/definitions"); 
    definition.afterPropertiesSet(); 

    StringResult wsdlResult = new StringResult(); 
    TransformerFactory.newInstance().newTransformer().transform(definition.getSource(), wsdlResult); 
    return wsdlResult.toString(); 
}

另一种选择可以是让从应用程序上下文已经配置豆：在

import static org.junit.Assert.fail; 
import java.io.File; 
import java.io.FileOutputStream; 
import java.io.IOException; 
import javax.xml.transform.Source; 
import javax.xml.transform.Transformer; 
import javax.xml.transform.TransformerException; 
import javax.xml.transform.TransformerFactory; 
import javax.xml.transform.stream.StreamResult; 
import org.junit.Test; 
import org.junit.runner.RunWith; 
import org.springframework.beans.factory.annotation.Autowired; 
import org.springframework.context.ApplicationContext; 
import org.springframework.test.context.ContextConfiguration; 
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner; 
import org.springframework.ws.wsdl.WsdlDefinition; 


@RunWith(SpringJUnit4ClassRunner.class) 
@ContextConfiguration(locations = {"classpath:yourWsdlConfig.xml"}) 
public class WsdlGeneratorTest { 

    @Autowired 
    private ApplicationContext ctx; 

    /* 
    * Path relative to module root (or absolute path can be used). 
    */ 
    private static final String OUTPUT_PATH = "target"; 

    @Test 
    public void test() { 
     String names[] = ctx.getBeanNamesForType(WsdlDefinition.class); 
     TransformerFactory tFactory = TransformerFactory.newInstance(); 
     for (String name : names) { 
      String filename = OUTPUT_PATH + File.separator + name + ".wsdl"; 
      WsdlDefinition wd = (WsdlDefinition) ctx.getBean(name); 
      Source source = wd.getSource(); 
      try { 
       Transformer transformer = tFactory.newTransformer(); 
       FileOutputStream fo = new FileOutputStream(filename); 
       StreamResult result = new StreamResult(fo); 
       transformer.transform(source, result); 
       fo.close(); 
      } catch (TransformerException e) { 
       fail("Error generating " + filename + ": TransformerException: " + e.getMessage()); 
      } catch (IOException e) { 
       fail("Error generating " + filename + ": IOException: " + e.getMessage()); 
      } 
     }   
    } 
}
