我有一个 Spring Boot 项目，我想删除 JPA。但是，执行此操作后，我在启动时看到以下内容

我的 gradle 部门看起来像这样

dependencies {

    testImplementation 'org.springframework.boot:spring-boot-starter-test'

    implementation platform('software.amazon.awssdk:bom:2.+')
    implementation 'software.amazon.awssdk:s3'
    implementation 'software.amazon.awssdk:rds'

    implementation 'org.springframework.boot:spring-boot-starter-actuator'
    implementation 'org.springframework.boot:spring-boot-starter-data-rest'
    implementation 'org.springframework.boot:spring-boot-starter-security'
    implementation 'org.springframework.boot:spring-boot-starter-oauth2-client'
    implementation 'org.springframework.boot:spring-boot-starter-oauth2-resource-server'
    implementation 'org.springframework.boot:spring-boot-starter-web'
    implementation 'org.springframework.boot:spring-boot-starter-data-cassandra'
    implementation 'org.springframework.boot:spring-boot-starter-webflux'
    implementation 'org.springframework.boot:spring-boot-autoconfigure'
    implementation 'org.springframework.kafka:spring-kafka'
    implementation 'jakarta.validation:jakarta.validation-api:3.0.2'
    implementation 'com.googlecode.libphonenumber:libphonenumber:8.12.39'

    compileOnly 'org.projectlombok:lombok'
    annotationProcessor 'org.projectlombok:lombok'
    testRuntimeOnly 'org.junit.platform:junit-platform-launcher'
}

我尝试添加

//    TODO Why do I need these
    implementation 'org.springframework.boot:spring-boot-starter-data-jpa'
    implementation 'org.flywaydb:flyway-core'
    implementation 'org.liquibase:liquibase-core'

以及我的 application.yml 中的以下内容

spring:
  flyaway:
    enabled: false

但我仍然遇到同样的错误。我缺少什么如何删除 JPA 并避免这些问题？我已确认没有类仍在使用 JPA 注释。

我还尝试删除 

implementation 'org.springframework.boot:spring-boot-autoconfigure'
依赖项并重新运行，奇怪的是我遇到了同样的问题

我也在使用 Java 21 (OpenJDK)

另一件事可能值得注意的是我使用

apply plugin: 'io.spring.dependency-management'

java spring spring-boot jpa

删除 JPA 后，您根本没有任何类负责数据库连接。至少添加 JDBC 依赖。像这样：

dependencies {
  implementation 'org.springframework.boot:spring-boot-starter-jdbc'
