Spring Boot REST API: Handling JSON Serialization implementing LocalDateTime in Response
I'm refactoring my project and I'm optimizing some code but I'm working on a project and hit a roadblock. I'm currently working with an scenario with my Spring Boot REST API where I need to return a `LocalDateTime` object as part of my JSON response. I'm using Spring Boot 2.5.4 and Jackson as the JSON processor. However, when I make a GET request to my endpoint, the `LocalDateTime` field is returning a serialized value that looks like this: `"2023-10-10T15:30:00.000+00:00"`, which includes timezone information. This is not the format I want; I need it to be in a specific format, such as `yyyy-MM-dd HH:mm:ss`. I've tried adding a `@JsonFormat` annotation to the `LocalDateTime` field in my DTO class, like so: ```java public class EventDto { private String name; @JsonFormat(shape = JsonFormat.Shape.STRING, pattern = "yyyy-MM-dd HH:mm:ss") private LocalDateTime eventTime; // getters and setters } ``` Despite this, the output remains unchanged. Additionally, I've ensured that my Jackson dependency is up to date in my `pom.xml`: ```xml <dependency> <groupId>com.fasterxml.jackson.datatype</groupId> <artifactId>jackson-datatype-jsr310</artifactId> <version>2.12.5</version> </dependency> ``` I've also registered the JavaTimeModule with my `ObjectMapper` in the configuration class: ```java @Bean public ObjectMapper objectMapper() { ObjectMapper mapper = new ObjectMapper(); mapper.registerModule(new JavaTimeModule()); return mapper; } ``` However, I'm still unable to achieve the desired format for the `LocalDateTime` in the JSON response. Is there anything I might be missing, or any additional configuration needed? Any insights or suggestions would be greatly appreciated! What am I doing wrong? This is for a application running on Windows 10. I'm open to any suggestions. I've been using Java for about a year now.
