Question

我正在尝试将现有的SOAP服务bean配置从XML转换为JAVA。我得到这个奇怪的问题，其中一些bean配置代码被多次执行。它不会影响功能，但在使用xml配置时不会发生这种情况。我在SpringConfig类中使用的Java配置是：

@Configuration
@ImportResource("classpath:webServices.xml")
public class mySpringConfig {

    public static int i = 0;

    @Inject
    ExceptionNormalizationAdvice exceptionNormalizationAdvice;

    @Inject
    private RequestHeaderInjectorAdvice requestHeaderInjectorAdvice;

    @Inject
    private CustomHandlerResolver customHandlerResolver;


     @Bean(name = "service1")
        public JaxWsPortProxyFactoryBean service1() {
            i++;
            System.out.println("inside s1 " + i);
            JaxWsPortProxyFactoryBean bean = new JaxWsPortProxyFactoryBean();
            List<Advice> adviceList = new ArrayList<Advice>();
            adviceList.add(exceptionNormalizationAdvice);
            adviceList.add(requestHeaderInjectorAdvice);
            bean.setAdviceList(adviceList);
            bean.setHandlerResolver(customHandlerResolver);
            bean.setServiceInterface(service1Soap.class); //
            bean.setNamespaceUri("http://example.com/service1");
            bean.setWsdlDocumentUrl(this.getClass().getClassLoader().getResource("service1.wsdl"));
            bean.setServiceName("service1");
            bean.setPortName("service1Soap");
            return bean;
        }

        @Bean(name = "service2")
        public JaxWsPortProxyFactoryBean service2() {
            i++;
            System.out.println("inside s2 " + i);
            JaxWsPortProxyFactoryBean bean = new JaxWsPortProxyFactoryBean();
            List<Advice> adviceList = new ArrayList<Advice>();
            adviceList.add(exceptionNormalizationAdvice);
            adviceList.add(requestHeaderInjectorAdvice);
            bean.setHandlerResolver(customHandlerResolver);
            bean.setAdviceList(adviceList);
            bean.setServiceInterface(service2Soap.class); //
            bean.setNamespaceUri("http://example.com/servic2");
            bean.setWsdlDocumentUrl(this.getClass().getClassLoader()
                    .getResource("service2.wsdl"));
            bean.setServiceName("service2");
            bean.setPortName("service2Soap");
            return bean;

        }
}

当我尝试打印文本并计算时，我得到了＃s;＆＃34; s1＆＃34;在计数4和8和＆＃34; s2＆＃34;内打印2次打印6次，计数范围从1到7，没有4。该服务的相应XML配置是这样的。仅列出了服务1用于示例，服务2使用了类似的配置。

<bean id="service1"
        class="JaxWsPortProxyFactoryBean">
        <property name="handlerResolver" ref="customHandleResolver" />
        <property name="serviceInterface" value="service1Soap" />
        <property name="wsdlDocumentUrl" value="classpath:META-INF/wsdls/service1.wsdl" />
        <property name="namespaceUri" value="http://example.com/service1" />
        <property name="serviceName" value="service1" />
        <property name="portName" value="service1Soap" />
        <property name="adviceList">
            <list>
                <ref bean="exceptionNormalizationAdvice"/>
                <ref bean="requestHeaderInjectorAdvice"/>
            </list>
  </property>
    </bean>

在服务类中，我使用以下方法注入工厂bean并使用代理与SOAP服务器通信。

@Resource(name="service1")
private service1Soap service1;

service1.callSomeMethod();

web.xml包含：

  <display-name>my-web</display-name>
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
  <context-param>
    <param-name>contextClass</param-name>
    <param-value>
          org.springframework.web.context.support.AnnotationConfigWebApplicationContext
      </param-value>
  </context-param>
  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>com.example.myown.core.CoreSpringConfig</param-value>
  </context-param>
  <context-param>
    <param-name>spring.profiles.active</param-name>
    <param-value>my-content</param-value>
  </context-param>
    <servlet>
    <servlet-name>spring</servlet-name>
    <servlet-class>
            org.springframework.web.servlet.DispatcherServlet
        </servlet-class>
    <init-param>
      <param-name>contextClass</param-name>
      <param-value>org.springframework.web.context.support.AnnotationConfigWebApplicationContext</param-value>
    </init-param>
    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>com.example.myown.web.WebMvcSpringConfig</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>spring</servlet-name>
    <url-pattern>/myweb/*</url-pattern>
  </servlet-mapping>
</web-app>

WebMvcSpringConfig和CoreSpringConfig都有@ComponentScan注释，并扫描相同的基础包（com.example.myown），CoreSpringConfig使用{WebMvcSpringConfig排除FilterType.Assignable_Type {1}}。

我面临的问题是，当我计算s1＆＃34;内部的次数时，＃34;并且＆＃34;在s2＆＃34;内它不止一次。我尝试在excludeFilter内为mySpringConfig类添加WebMvcSpringConfig，现在一些冗余事件已经消失但并非全部。只需将mySpringConfig文件（如上所示）的输出设为：

inside s2 1
inside s2 2
inside s2 3
inside s1 4

如果我将service1()函数移到下面并将service2()函数移到顶部，则输出也会与此互换：

inside s1 1
inside s1 2
inside s1 3
inside s2 4

如何更改类中函数的位置会改变输出？理想情况下，两者都应该只打印一次。我尝试在所有地方搜索@ComponentScan，但它仅用于核心弹簧配置和WebMVCSpringConfig文件，而不是其他任何地方。我确信bean已初始化并正确配置，因为上述问题不会对功能造成任何问题。

注意：导入webservices.xml以配置其他休息服务，并在xml文件中注释掉soap服务。

多次调用JaxWsPortProxyBean？
