GWT + Spring +未定義名為“ dispatch”的bean

Question

在嘗試使用spring依賴注入而不是guice時 ，出現錯誤以下

沒有定義名為“ dispatch”的 bean

[WARN] /dispatch/
org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'dispatch' is defined
    at org.springframework.beans.factory.support.DefaultListableBeanFactory.getBeanDefinition(DefaultListableBeanFactory.java:527)

您能幫上忙嗎？

web.xml內容如下

<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath*:META-INF/applicationContext.xml</param-value>
</context-param>



<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>


<servlet>
<servlet-name>dispatch</servlet-name>
<servlet-class>org.springframework.web.context.support.HttpRequestHandlerServlet</servlet-class>
</servlet>

<servlet-mapping>
<servlet-name>dispatch</servlet-name>
<url-pattern>/dispatch/*</url-pattern>
</servlet-mapping>

SeverModule類是

package com.khush.util.server.spring;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Import;

import com.gwtplatform.dispatch.server.actionvalidator.ActionValidator;
import com.gwtplatform.dispatch.server.spring.HandlerModule;
import com.gwtplatform.dispatch.server.spring.actionvalidator.DefaultActionValidator;
import com.gwtplatform.dispatch.server.spring.configuration.DefaultModule;
import com.khush.util.shared.action.RetrieveAccountsAction;

@Configuration
@Import(DefaultModule.class)
public class ServerModule extends HandlerModule {

  public ServerModule() {
  }

  @Bean
  public RetrieveAccountsHandler getRetrieveAccountsHandler() {
    return new RetrieveAccountsHandler();
  }

  @Bean
  public ActionValidator getDefaultActionValidator() {
    return new DefaultActionValidator();
  }

  protected void configureHandlers() {
      bindHandler(RetrieveAccountsAction.class, RetrieveAccountsHandler.class);
  }
}

問候。

您可以在此處粘貼applicationContext.xml的內容嗎？ 我認為您忘記添加標簽：

<context:component-scan base-package="package to scan..."/>

沒有這個標簽，Spring將無法在XML文件之外檢測到Bean。
