升级到springboot 2.5.6后的Java 8序列化异常

Question

当我升级到sprngboot 2.5.6时，我得到了java.io.UncheckedIOException: com.fasterxml.jackson.databind.exc.InvalidDefinitionException: Java 8 date/time type java.time.LocalDateTime not supported by default: add Module "com.fasterxml.jackson.datatype:jackson-datatype-jsr310" to enable handling。我在网上尝试了几个解决方案，但没有发现对我有帮助。添加了以下依赖项

<dependency>
    <groupId>com.fasterxml.jackson.datatype</groupId>
    <artifactId>jackson-datatype-jsr310</artifactId>
    <version>2.11.3</version>
    <scope>provided</scope>
</dependency>
<dependency>
    <groupId>com.fasterxml.jackson.datatype</groupId>
    <artifactId>jackson-datatype-jdk8</artifactId>
</dependency>

拥有以下自定义对象映射程序，但禁用它也不起作用

 @Bean
    @Primary
    public ObjectMapper objectMapper() {

        return new ObjectMapper()
                .setSerializationInclusion(JsonInclude.Include.NON_NULL)
                .configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false)
                .registerModule(new JavaTimeModule())
                .registerModule(new Jdk8Module())
                .registerModule(new DefaultScalaModule())
                .enable(DeserializationFeature.READ_UNKNOWN_ENUM_VALUES_USING_DEFAULT_VALUE)
                .findAndRegisterModules();

我能够用ZonedDateTime而不是LocalDateTime修复这个问题。
