使用 spring boot 配置 SOAP 服务时出错

【中文标题】使用 spring boot 配置 SOAP 服务时出错

【英文标题】：Error in configuring SOAP service with spring boot

【问题描述】：

我正在尝试将 SOAP Web 服务与 Spring Boot 一起使用。我能够让它与 Spring MVC 应用程序一起工作（使用 web.xml 而没有 spring boot），但我被困在使用 Spring boot xml free setup 进行配置。

下面是我尝试为其生成 wsdl 的示例服务的代码。

@WebService(serviceName="AddService", targetNamespace="http://add.sample.net/service/", name="addService", portName="adService")
public class MathOps extends SpringBeanAutowiringSupport 

    @WebMethod
    public int add(int a, int b)
        return (a+b);
    

我的 Spring Boot 配置如下：

@Configuration
@EnableAutoConfiguration
@ComponentScan
public class Application extends SpringBootServletInitializer 
    public static void main(final String[] args) 
        SpringApplication.run(Application.class, args);
    

    @Override
    protected final SpringApplicationBuilder configure(final SpringApplicationBuilder application) 
        application.logStartupInfo(true);
        return application.sources(Application.class);
    

    @Override
    public void onStartup(final ServletContext servletContext) throws ServletException 
        super.onStartup(servletContext);
        servletContext.addListener(new ContextLoaderListener());
        servletContext.addListener(new WSServletContextListener());

    

    @Bean
    public ServletRegistrationBean wsServlet()
        ServletRegistrationBean wsServletBean = new ServletRegistrationBean(new WSSpringServlet(), "/services");
        return wsServletBean;
    

当我点击 URL localhost:8080/services 时，我收到以下错误。

出现意外错误（类型=未找到，状态=404）。 /服务/

似乎对于 url 映射 /services，dispatcherServlet 被调用，而不是从下面的日志中调用 WSSpringServlet。

[2015-11-07 10:13:00.314] boot - 500 INFO [localhost-startStop-1] --- ServletRegistrationBean: 映射 servlet: 'WSSpringServlet' 到 [/services] [2015-11-07 10:13:00.316] 启动 - 500 信息 [localhost-startStop-1] --- ServletRegistrationBean：映射 servlet：'dispatcherServlet' 到 [/] [2015-11-07 10:13:01.405] boot - 500 INFO [main] --- Application: Started Application in 5.642 seconds (JVM running for 5.961) [2015-11-07 10:13:10.407] 启动 - 500 信息 [http-nio-8080-exec-1] --- [/]: 初始化 Spring FrameworkServlet 'dispatcherServlet' [2015-11-07 10:13:10.408] 启动 - 500 信息 [http-nio-8080-exec-1] --- DispatcherServlet：FrameworkServlet 'dispatcherServlet'：初始化开始 [2015-11-07 10:13:10.425] boot - 500 INFO [http-nio-8080-exec-1] --- DispatcherServlet：FrameworkServlet 'dispatcherServlet'：初始化在 17 毫秒内完成

下面是不用spring boot的web.xml配置。

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">

    <listener>
        <listener-class>
            org.springframework.web.context.ContextLoaderListener
        </listener-class>
    </listener>
  <display-name>Archetype Created Web Application</display-name>

  <servlet>
    <servlet-name>MyTest</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
  </servlet>

  <servlet-mapping>
    <servlet-name>MyTest</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>

  <servlet>
    <servlet-name>TestService</servlet-name>
    <servlet-class>com.sun.xml.ws.transport.http.servlet.WSSpringServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
  </servlet>

  <servlet-mapping>
    <servlet-name>TestService</servlet-name>
    <url-pattern>/services</url-pattern>
  </servlet-mapping>
</web-app>

请帮助解决这个问题。

【问题讨论】：

去掉监听器的注册，只留下servlet。您可能需要设置 order 属性，以便它在调度程序 servlet 之前注册。

【参考方案1】：

我终于设法让服务与 Spring Boot 一起工作:)。

唯一缺少的代码是导入包含 Web 服务绑定的 XML 配置。

以下是更新后的 WebService 配置类，用于在 Spring Boot 中配置基于 SOAP 的服务。

@Configuration
@EnableWs
@ImportResource("classpath:/applicationContext.xml")
public class WebServiceConfiguration extends WsConfigurerAdapter 

    @Bean
    public ServletRegistrationBean wsServlet()
        ServletRegistrationBean wsServletBean = new ServletRegistrationBean(new WSSpringServlet(), "/services/*");
        wsServletBean.setLoadOnStartup(1);
        //wsServletBean.setInitParameters(initParameters);
        return wsServletBean;
    

下面还有放在类路径中的applicationContext.xml。

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:ws="http://jax-ws.dev.java.net/spring/core" xmlns:wss="http://jax-ws.dev.java.net/spring/servlet"
xsi:schemaLocation=
    "http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
    http://jax-ws.dev.java.net/spring/core
    http://jax-ws.java.net/spring/core.xsd
    http://jax-ws.dev.java.net/spring/servlet
    http://jax-ws.java.net/spring/servlet.xsd">

  <wss:binding url="/services/MathService">
    <wss:service><!-- nested bean is of course fine -->
      <ws:service bean="#MathService" />
    </wss:service>
  </wss:binding>

  <wss:binding url="/services/StringService">
    <wss:service><!-- nested bean is of course fine -->
      <ws:service bean="#StringService" />
    </wss:service>
  </wss:binding>

  <!-- this bean implements web service methods -->
  <bean id="MathService" class="com.trial.services.MathOps" />
  <bean id="StringService" class="com.trial.services.StringOps" />
</beans>

希望它可以帮助在 Spring Boot 和 SOAP 服务配置方面面临类似问题的人。 :)
