使用 spring boot 配置 SOAP 服務時出錯

Question

我正在嘗試在 Spring Boot 中使用 SOAP Web 服務。 我能夠讓它與 Spring MVC 應用程序一起工作（使用 web.xml 而不使用 spring boot），但我堅持使用 Spring boot xml free setup 進行配置。

下面是我正在嘗試為其生成 wsdl 的示例服務的代碼。

@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;
    }
}

當我點擊 URL localhost:8080/services 時，出現以下錯誤。

出現意外錯誤（類型=未找到，狀態=404）。 /服務/

似乎對於 url 映射 /services，從下面的日志中調用 dispatcherServlet 而不是 WSSpringServlet。

[2015-11-07 10:13:00.314] boot - 500 INFO [localhost-startStop-1] --- ServletRegistrationBean: Mapping servlet: 'WSSpringServlet' to [/services] [2015-11-07 10:13:00.316 ] boot - 500 INFO [localhost-startStop-1] --- ServletRegistrationBean: Mapping servlet: 'dispatcherServlet' to [/] [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] boot - 500 INFO [http-nio-8080-exec-1] --- [/]: Initializing Spring FrameworkServlet ' dispatcherServlet' [2015-11-07 10:13:10.408] boot - 500 INFO [http-nio-8080-exec-1] --- DispatcherServlet: FrameworkServlet 'dispatcherServlet': 初始化開始 [2015-11-07 10:13] :10.425] boot - 500 INFO [http-nio-8080-exec-1] --- DispatcherServlet: FrameworkServlet 'dispatcherServlet': 初始化在 17 ms 內完成

沒有 spring boot 的 web.xml 配置如下。

<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>

請幫助解決這個問題。

Answer 1

我終於設法讓服務與 Spring Boot 一起工作:)。

唯一缺少的代碼是導入包含 Web 服務綁定的 XML 配置。

下面是更新的 WebService 配置類，用於在 Spring Boot 中配置基於 SOAP 的服務。

@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;
    }
}

下面還有放置在類路徑中的 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>

希望它可以幫助那些面臨 Spring Boot 和 SOAP 服務配置類似問題的人。 :)
