尝试使用AbstractAnnotationConfigDispatcherServletInitializer而不是web.xml来初始化Web应用程序。配置文件如下：

public class FSSWebInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {

  @Override
  protected Class<?>[] getRootConfigClasses() {
    System.out.println("********** getRootConfigClasses");

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

  @Override
  protected Class<?>[] getServletConfigClasses() {
    System.out.println("********** getServletConfigClasses");

    return new Class[] {FSSServletConfig.class};
//    return null;
  }

  @Override
  protected String[] getServletMappings() {
    System.out.println("********** getServletMappings");

    return new String[] {"/" };
  }
}

@Configuration
@EnableWebMvc
//@ComponentScan(basePackages= {"com.fss.web", "com.xps"})
@ComponentScan(basePackageClasses= {TestController.class})

@ImportResource({ 
    "/WEB-INF/dispatcher-servlet.xml" 
  }
)
public class FSSServletConfig extends WebMvcConfigurerAdapter {
  public FSSServletConfig() {
    System.out.println("********** FSSServletConfig");
  }

  @Bean
  public GeneralSearchCgiDao generalSearchService() {
    return new GeneralSearchCgiDao();
  }
}

@Configuration
@ImportResource({ 
    "classpath:com/fss/application/ctx/applicationContext-cgi.xml", 
    "classpath:com/fss/application/ctx/applicationContext-pl.xml",
    "classpath:com/fss/application/ctx/connectionSetup.xml", 
    "/WEB-INF/session-beans.xml", 
    "/WEB-INF/alert-mapping-properties.xml", 
    "/WEB-INF/key-mapping.xml",
    "/WEB-INF/report-mapping-properties.xml"
    ,"/WEB-INF/common.xml"
  }
)
public class FSSRootConfig {
  public FSSRootConfig() {
    System.out.println("********** FSSRootConfig");
  }

  @Bean
  public RemoteCPStatus remoteCPStatus() {
    return new RemoteCPStatus();
  }

  @Bean
  public CgiEnviromentService cgiEnviromentService() {
    return new CgiEnviromentService();
  }
}

出现以下错误：

wonder what did I miss in these new config.  This is a working application with web.xml where we have:

       <context-param>
                <param-name>contextConfigLocation</param-name>
                <param-value>
                        classpath:com/fss/application/ctx/applicationContext-cgi.xml
                        classpath:com/fss/application/ctx/applicationContext-pl.xml
                        classpath:com/fss/application/ctx/connectionSetup.xml
                        /WEB-INF/session-beans.xml
                        /WEB-INF/alert-mapping-properties.xml
                    /WEB-INF/key-mapping.xml
                        /WEB-INF/report-mapping-properties.xml
                </param-value>
        </context-param>


...

        <servlet>
                <servlet-name>Dispatcher</servlet-name>
                <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
                <init-param>
                        <param-name>contextConfigLocation</param-name>
                        <param-value>/WEB-INF/fids-servlet-config.xml</param-value>
                </init-param>
        </servlet>

尝试了许多不同的调整，没有任何作用。

答案 0 :(得分：1)

事实证明，如果单例具有会话范围bean的自动连接字段，则会发生此错误。它需要设置代理： @Scope（value =＆＃34; session＆＃34;，proxyMode = ScopedProxyMode.TARGET_CLASS）

这让人感觉到了。但令我感到困惑的是旧方式允许它。

我发布此解决方案，以防其他人遇到与我相同的问题。

谢谢！
