没有匹配的类型的bean ...找到依赖

经过几天尝试并在泉源论坛上寻找答案后,我会在这里试试.运行我的应用程序会导致以下异常:

WebMvcConfigurationSupport和WebMvcConfigurerAdapter之间的区别

我想添加资源处理程序.在他们使用的论坛中WebMvcConfigurationSupport:http://forum.springsource.org/showthread.php？116068-How-to-configure-lt-mvc-resources-gt-mapping-to-take-precedence-over-RequestMapping&p=384066# post384066

和文档说WebMvcConfigurerAdapter:http://static.springsource.org/spring/docs/3.2.x/javadoc-api/org/springframework/web/servlet/config/annotation/EnableWebMvc.html

有什么区别,使用哪一个？两者都有addResourceHandlers我需要的方法.

这是我目前的课程:

@Configuration
@EnableWebMvc
public class WebMvcConfig extends WebMvcConfigurerAdapter {
    public @Override void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/resources/**").addResourceLocations("/resources");
    }

    public @Bean TilesViewResolver tilesViewResolver() {
        return new TilesViewResolver();
    }

    public @Bean TilesConfigurer tilesConfigurer() {
        TilesConfigurer ret = new TilesConfigurer();
        ret.setDefinitions(new String[] { "classpath:tiles.xml" });
        return ret;
    }
}

Spring Controller中的PathVariable

我正在尝试映射网址/locations/{locationId}/edit.html - 这似乎与此代码一起使用:

@Controller
@RequestMapping( "/locations" )
public class LocationController
{
  @RequestMapping( value = "/{locationId}/edit.html", method = RequestMethod.GET )
  public String showEditForm( Map<String, Object> map, @PathVariable int locationId )
  {
    map.put( "locationId", locationId );
    return "locationform";
  }
}
