JDK 17 spring boot 无法将 java.time.LocalDateTime 设为私有

Question

我在简单的 mongodb 实体中有私有 LocalDateTime lastModifiedDate 属性。 使用最新的 2.5.5 和 openjdk 17 运行应用程序

Following exeptions I have with date time
Caused by: java.lang.reflect.InaccessibleObjectException: Unable to make private java.time.LocalDateTime(java.time.LocalDate,java.time.LocalTime) accessible: module java.base does not "opens java.time" to unnamed module @61baa894

即使我删除了 lombok，所以我们应该再次回滚到 Java 1.8？:)

Answer 1

据我了解，我们需要添加以下 Java OPT 参数：

 - JVM_OPTS=  --add-exports=java.naming/com.sun.jndi.ldap=ALL-UNNAMED --add-opens=java.base/java.lang=ALL-UNNAMED --add-opens=java.base/java.lang.invoke=ALL-UNNAMED --add-opens=java.base/java.io=ALL-UNNAMED --add-opens=java.base/java.security=ALL-UNNAMED --add-opens=java.base/java.util=ALL-UNNAMED --add-opens=java.management/javax.management=ALL-UNNAMED --add-opens=java.naming/javax.naming=ALL-UNNAMED

例如我在 docker compose 中添加的。

我认为 Spring boot/JakartaEE 很快就会升级它们的配置。

Answer 2

有同样的问题。不要使用 gson 映射器。从 application.properties 文件中删除下一行。

spring.mvc.converters.preferred-json-mapper=gson
