1. On pom.xml

  <dependency>
     <groupId>com.fasterxml.jackson.datatype</groupId>
     <artifactId>jackson-datatype-jsr310</artifactId>
     <version>2.9.8</version>
  </dependency>
  
2. On application.properties

  spring.jackson.serialization.write_dates_as_timestamps=false

  @JsonFormat(shape = JsonFormat.Shape.STRING, pattern = "yyyy-MM-dd HH:mm:ss")
  private LocalDateTime dateIntegration;
