Spring Boot迁移后配置ant_path_matcher不生效问题求助

背景 #

正在将Spring Boot从2.5版本迁移至3.4版本（当前处于3.0版本），由于新版本中ant_path_matcher不再是默认路径匹配策略，因此在application.yaml中添加了如下配置：

spring:
  mvc:
    pathmatch:
      matching-strategy: ant_path_matcher

该配置此前多次解决过同类问题，但本次报错仍持续存在。

WebMvcConfig配置 #

以下是WebMvcConfig.kt文件内容：

package our.application.path.configuration

import com.fasterxml.jackson.databind.ObjectMapper
import org.springframework.context.annotation.Bean
import org.springframework.context.annotation.Configuration
import org.springframework.http.converter.json.MappingJackson2HttpMessageConverter
import org.springframework.web.cors.CorsConfiguration
import org.springframework.web.cors.CorsConfigurationSource
import org.springframework.web.cors.UrlBasedCorsConfigurationSource
import org.springframework.web.servlet.config.annotation.EnableWebMvc
import org.springframework.web.servlet.config.annotation.ViewControllerRegistry
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer

@Configuration
@EnableWebMvc
class WebMvcConfig : WebMvcConfigurer {
    companion object {
        // Forwarding target
        const val FORWARD_INDEX_HTML = "forward:/index.html"
    }

    override fun addViewControllers(registry: ViewControllerRegistry) {
        // Map "/" to /index.html
        registry.addViewController("/").setViewName(FORWARD_INDEX_HTML)

        // Single directory level - no need to exclude "api"
        registry.addViewController("/{x:[\\w\\-]+}").setViewName(FORWARD_INDEX_HTML)
        // Multi-level directory path, need to exclude "api" on the first part of the path
        registry.addViewController("/{x:^(?!api$).*$}/**/{y:[\\w\\-]+}").setViewName(FORWARD_INDEX_HTML)
    }

    @Bean
    fun corsConfigurationSource(): CorsConfigurationSource {
        val source = UrlBasedCorsConfigurationSource()
        source.registerCorsConfiguration("/**", CorsConfiguration().applyPermitDefaultValues())
        return source
    }


    @Bean
    open fun mappingJackson2HttpMessageConverter(objectMapper: ObjectMapper): MappingJackson2HttpMessageConverter {
        return MappingJackson2HttpMessageConverter(objectMapper)
    }
}

启动错误日志 #

无论是否添加上述yaml配置，应用启动末尾都会出现如下错误：
