Spring-ws javaconfig位置转换

Question

我正在尝试使用 Java-Config 设置 Web 服务项目（目前是 SOAP - 但最终会添加 REST）。不幸的是，我无法自动公开 WSDL（据推测，Spring 可以根据 XSD 生成它并公开它）。

我找到的唯一文档在定义 servlet (web.xml) 时使用了 xml 配置。

<init-param>
    <param-name>transformWsdlLocations</param-name>
    <param-value>true</param-value>
</init-param>

如何使用 Java-config 完成此操作？

WebApplicationInitializer

public class WebApplicationInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {

/**
 * {@inheritDoc} 
 */
@Override
protected Class<?>[] getRootConfigClasses() {

    return new Class[] {WebSecurityConfiguration.class};
}

/**
 * {@inheritDoc} 
 */
@Override
protected Class<?>[] getServletConfigClasses() {

    return new Class[] {WebServicesConfiguration.class};
}

/**
 * {@inheritDoc} 
 */
@Override
protected String[] getServletMappings() {

    // get all mappings
    return new String[] { "/" };
}

Web 服务配置

@EnableWs
@Configuration
@ComponentScan("com.questsoftware")
public class WebServicesConfiguration extends WsConfigurationSupport {


@Bean
public XsdSchema schema() {

    return new SimpleXsdSchema(new ClassPathResource("lookup.xsd"));
}

@Bean
public DefaultWsdl11Definition defaultWsdl11Definition() {

    DefaultWsdl11Definition wsdl11Definition = new DefaultWsdl11Definition();
    wsdl11Definition.setTargetNamespace("http://com/[mycompany]/Lookup");
    wsdl11Definition.setPortTypeName("Lookup");
    wsdl11Definition.setLocationUri("/Lookup");
    wsdl11Definition.setSchema(schema());

    return wsdl11Definition;
}

需要说明的是 - 我还有一个 WebApplicationConfiguration (REST) - 但我还没有将它添加到 WebApplicationInitializer 中（运行先解决这个问题）。

WebApplicationConfiguration

@EnableWebMvc
@EnableAspectJAutoProxy(proxyTargetClass = true)
@Configuration
@ComponentScan("com.mycompany")
public class WebApplicationConfiguration extends WebMvcConfigurerAdapter {


/**
 * Defines {@link JdbcTemplate} as a Spring managed bean.
 * 
 * @return 
 */
@Bean
public JdbcTemplate jdbcTemplate() {

    return new JdbcTemplate(dataSource());
}

@Bean
public DataSource dataSource() {

    ...

    return dataSource;
}

/**
 * Defines a {@link ViewResolver} as a Spring managed bean.
 * 
 * @return the viewResolver
 */
@Bean
public ViewResolver viewResolver() {

    final InternalResourceViewResolver resolver = new InternalResourceViewResolver();
    resolver.setPrefix("/WEB-INF/pages");
    resolver.setSuffix(".jsp");

    return resolver;
}

/**
 * Registers resource handlers with Spring.
 * 
 * @param registry the {@link ResourceHandlerRegistry}
 */
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {

    registry.addResourceHandler("/view/**").addResourceLocations("/view/");
}

Answer 1

我想出了一个解决方案，但我不完全确定它是 'correct' 还是 'preferred' 方式。

我遵循了教程并简单地在基于 java-config 的 WebApplicationConfiguration 中定义了 beans，这些 bean 在基于教程 xml 的配置中定义。 --我的理解是，真的没有根本的区别，你只需要将 bean 添加到 Spring 容器中，所以 Spring 可以发挥它的魔力。

我对上面的代码进行了以下更改：

WebApplicationConfiguration

添加了以下bean

/**
 * Defines the {@link SaajSoapMessageFactory} as a Spring managed bean.
 * 
 * Note: we need a Soap implementation of a MessageFactory to create soap messages in Spring-WS.
 * 
 * @return the messageFactory
 */
@Bean
public SaajSoapMessageFactory messageFactory() {

    return new SaajSoapMessageFactory();
}

/**
 * Defines the {@link WebServiceMessageReceiverHandlerAdapter} as a Spring managed bean.
 * 
 * Note: We need to add this bean to the context in order for the DispatcherServlet to delegate to a MessageDispatcher 
 * (as opposed to Controllers).  The MessageDispatcher is necessary for Spring-WS.
 * 
 * @return the webServiceMessageReceiverHandlerAdapter
 */
@Bean
public WebServiceMessageReceiverHandlerAdapter webServiceMessageReceiverHandlerAdapter() {

    WebServiceMessageReceiverHandlerAdapter adapter = new WebServiceMessageReceiverHandlerAdapter();
    adapter.setMessageFactory(messageFactory());

    return adapter;
}

/**
 * Defines the {@link SimpleUrlHandlerMapping} as a Spring managed bean.
 * 
 * Note: In order for the DispatcherServlet to handle SOAP message, we were forced to add the {@link WebServiceMessageReceiverHandlerAdapter}
 * to the context. By explicitely adding that bean to the context, we are now forced to also add this bean to handle REST messages.
 * 
 * @return the simpleUrlHandlerMapping
 */
@Bean
public SimpleUrlHandlerMapping simpleUrlHandlerMapping() {

    SimpleUrlHandlerMapping simpleUrlHandlerMapping = new SimpleUrlHandlerMapping();
    simpleUrlHandlerMapping.setDefaultHandler(messageDispatcher());
    Properties urlProperties = new Properties();

    urlProperties.put("Lookup.wsdl", "Lookup");

    simpleUrlHandlerMapping.setMappings(urlProperties);
    simpleUrlHandlerMapping.setDefaultHandler(messageDispatcher());

    return simpleUrlHandlerMapping;
}

/**
 * Defines the {@link SoapMessageDispatcher} as a Spring managed bean.
 * 
 * Note: Dispatches SOAP messages.
 * 
 * @return the messageDispatcher
 */
@Bean 
public SoapMessageDispatcher messageDispatcher() {

    return new SoapMessageDispatcher();
}

/**
 * Defines the {@link SimpleControllerHandlerAdapter} as a Spring managed bean.
 * 
 * Note: In order for the DispatcherServlet to handle SOAP messages, we were forced to add the {@link WebServiceMessageReceiverHandlerAdapter}
 * to the context.  By explicitely adding that bean to the context, the default adapters were not automatically added to handle 
 * standard MVC Controllers.  We must add this bean to do that.
 * 
 * @return the simpleControllerHandlerAdapter
 */
@Bean
public SimpleControllerHandlerAdapter simpleControllerHandlerAdapter() {

    return new SimpleControllerHandlerAdapter();
}

Web 服务配置

删除了@ComponentScan("com.mycompany") - WebApplicationConfiguration 已经为我完成了这个，实际上在这个配置中获取了所有的 beans .

添加了以下bean

@Bean
public WsdlDefinitionHandlerAdapter wsdlDefinitionHandlerAdapter() {

    WsdlDefinitionHandlerAdapter wsdlDefinitionHandlerAdapter = new WsdlDefinitionHandlerAdapter();
    wsdlDefinitionHandlerAdapter.setTransformLocations(true);

    return wsdlDefinitionHandlerAdapter;
}

注意！！！ - 在 WsdlDefinitionHandlerAdapter 的 bean 定义中，我将 setter 称为 transformLocations。这与 WebApplicationConfig 中的 urlMapping 一起是公开 WSDL 的关键。当然其他 bean 是必需的，但这是原始问题的要点。
