Spring Boot 3.x集成Swagger UI失败：无法访问Web界面求助

我在Spring Boot 3.2.1版本中尝试运行Swagger UI，但无法通过地址 http://localhost:8080/webjars/swagger-ui/index.html#/ 访问Web界面。打开页面时显示资源找不到错误（提示无静态资源swagger-ui/index.html），且Docker容器无相关日志输出。

初始 build.gradle 配置 #

plugins {
    id 'java'
    id 'org.springframework.boot' version '3.2.1'
    id 'io.spring.dependency-management' version '1.1.4'
}

group = 'com.naman.jain'
version = '0.0.1-SNAPSHOT'

java {
    sourceCompatibility = '17'
}

configurations {
    compileOnly {
        extendsFrom annotationProcessor
    }
}

repositories {
    mavenCentral()
}

// Disables the default jar task, preventing the creation of a JAR file during the build process.
// This is useful in scenarios where the project does not require a JAR file,
// such as when only a WAR file is needed or in specific modules of a multi-module project.
jar {
    enabled = false
}


dependencies {
    implementation project(':api')
    implementation project(':util')

    implementation 'org.springframework.boot:spring-boot-starter-actuator'
    implementation 'org.springframework.boot:spring-boot-starter-webflux'

    // https://mvnrepository.com/artifact/org.springdoc/springdoc-openapi-starter-webflux-ui

    implementation 'org.springdoc:springdoc-openapi-starter-webflux-ui:2.5.0'

    // To avoid the following error message on Apple silicon (for details, see https://github.com/netty/netty/issues/11693):
    // Unable to load io.netty.resolver.dns.macos.MacOSDnsServerAddressStreamProvider, fallback to system defaults. This may result in incorrect DNS resolutions on MacOS.

更新尝试：升级版本后问题仍未解决 #

已升级到Spring Boot 3.3.3和springdoc-openapi-starter-webflux-ui 2.6.0，但访问Swagger UI的问题依旧存在，更新后的build.gradle配置如下：

plugins {
    id 'java'
    id 'org.springframework.boot' version '3.3.3'
    id 'io.spring.dependency-management' version '1.1.6'
}

version = '0.0.1-SNAPSHOT'

java {
    sourceCompatibility = '17'
}

configurations {
    compileOnly {
        extendsFrom annotationProcessor
    }
}

repositories {
    mavenCentral()
}

// Disables the default jar task, preventing the creation of a JAR file during the build process.
// This is useful in scenarios where the project does not require a JAR file,
// such as when only a WAR file is needed or in specific modules of a multi-module project.
jar {
