Java 创建名为'；defaultServletHandlerMapping

这是eclipse上的spring（具有spring安全）+java+maven应用程序。我在提交注册表单时遇到以下错误。随后请参阅我的其他文件：

HTTP Status 500 - Request processing failed; nested exception is 
org.springframework.beans.factory.BeanCreationException:
 Error creating bean with name 'defaultServletHandlerMapping' defined in class 
org.springframework.web.servlet.config.annotation.DelegatingWebMvcConfiguration:

我很抱歉放了很多东西。我已经尝试过解决类似的问题，但没有成功。任何暗示都将不胜感激。提前谢谢

我在这个平台上的一个类似问题的解决方案的帮助下解决了这个问题

通过在myappconfig文件中添加以下注释，我排除了扫描配置筛选器：

        repository.setSessionAttributeName("_csrf");
        return repository;

    @Override

            .csrfTokenRepository(csrfTokenRepository())
            .and()
        .authorizeRequests()

@EnableWebMvc 
@Configuration
@ComponentScan(
  basePackages ={ "com.myapp" }, 
  excludeFilters = { 
    @Filter(type = FilterType.ANNOTATION, value = Configuration.class)
  }
)

这样做之后，问题没有得到解决

然后我删除了

@EnableWebMvc

，并将其放入myappinit文件，问题就解决了

我猜

@EnableWebMvc

和

@ComponentScan（basePackages={“com.myapp”}，excludeFilters={
@筛选器（type=FilterType.ANNOTATION，value=Configuration.class）}）

不应位于同一配置文件中。

请尝试删除文件AppInit一秒钟，然后重新生成应用程序！告诉我它是否有用@阿琼先生，我试过了，但问题并没有解决。我想问题在于注册控制器的级别。不知何故，请求处理程序没有得到很好的定义。但我不知道该怎么做。此外，我找不到程序试图创建和实例化的“defaultHandlerBean”。谢谢！
