Spring Boot 3.5 升到 4.0:只改版本号,会遇到哪些编译和启动错误

  3.5.16:解析成功,103 个 jar,其中 spring-boot-* 模块 6 个
  4.0.8(去掉 aop 之后的 6 个 starter):解析成功,120 个 jar,其中 spring-boot-* 模块 25 个
  4.0.8 加上 spring-boot-starter-aop:解析失败 → 'dependencies.dependency.version' for org.springframework.boot:spring-boot-starter-aop:jar is missing. @ line 
  4.0.8 里新增的 spring-boot 模块名(3.5 没有同名的)共 19 个,例如:spring-boot-data-commons、spring-boot-data-jpa、spring-boot-health、spring-boot-hibernate、spring-boot-http-converter、spring-boot-jackson、spring-boot-jdbc、spring-boot-jpa
  Jackson:3.5.16:jackson-databind-2.21.4 / 4.0.8:jackson-databind-3.1.5
  Hibernate:3.5.16:hibernate-core-6.6.53.Final / 4.0.8:hibernate-core-7.2.24.Final

  3.5.16:通过 32 个,失败 0 个
  4.0.8:通过 9 个,失败 23 个

  按同名找到新位置的 19 个,同名类不存在的 4 个:MockBean、SpyBean、JsonComponent、Jackson2ObjectMapperBuilderCustomizer
  用新全限定名在加了对应模块的 classpath 上编译:通过 19 / 19 个

    MockitoBean  通过  (org.springframework.test.context.bean.override.mockito)
    MockitoSpyBean  通过  (org.springframework.test.context.bean.override.mockito)
    JacksonComponent  通过  (org.springframework.boot.jackson)
    JsonMapperBuilderCustomizer  通过  (org.springframework.boot.jackson.autoconfigure)
  对应关系(旧 → 新):MockBean → MockitoBean、SpyBean → MockitoSpyBean(都在 spring-test 里);JsonComponent → JacksonComponent;Jackson2ObjectMapperBuilderCustomizer → JsonMapperBuilderCustomizer(只验证了这四个新名字存在、能编译)

  classpath 223 个 jar(多出 103 个),旧 import 通过 9 / 32(没加之前 9)
  新增的 classic 相关 jar:logback-classic-1.5.38、spring-boot-starter-classic-4.0.8、spring-boot-autoconfigure-classic-4.0.8、spring-boot-autoconfigure-classic-modules-4.0.8、spring-boot-starter-test-classic-4.0.8、spring-boot-test-classic-modules-4.0.8
  加了 classic 之后仍然编译失败的 23 个:MockBean、SpyBean、ObjectMapper、JsonComponent、Jackson2ObjectMapperBuilderCustomizer、DataSourceProperties、HealthIndicator、AutoConfigureMockMvc、WebMvcTest、DataJpaTest、EntityScan、RestTemplateBuilder、TestRestTemplate、PathRequest、HttpMessageConverters、ServerProperties、HibernateJpaAutoConfiguration、HibernatePropertiesCustomizer、WebMvcAutoConfiguration、ErrorViewResolver、ErrorAttributes、TransactionProperties、CacheManagerCustomizer

  4.0.8:启动成功;GET /hello 不带凭证 → 401;带凭证 → 200 {"n":1,"msg":"hi"} (application/json);GET /actuator/health → 200 {"groups":["liveness","readiness"],"status":"UP"}
