Deeply complicated JPA mapping producing tables with NULL values - spring-boot

Question

Below are the entities (assume getters and setters):
#Entity
#Table(name="report_yearly")
public class AnalyticsReportYearly
{
#Id
#GeneratedValue(strategy=GenerationType.IDENTITY)
private long reportId;
private long viewId;
private long startYear;
private long endYear;
#JsonManagedReference
#OneToOne(cascade = CascadeType.ALL)
#JoinColumn(name="data_id", referencedColumnName = "dataId")
private AnalyticsData data;
#JsonManagedReference
#OneToOne(cascade = CascadeType.ALL)
#JoinColumn(name="column_header_id", referencedColumnName = "columnHeaderId")
private AnalyticsColumnHeader columnHeader;
}
#Entity
#Table(name="report_monthly")
public class AnalyticsReportMonthly
{
#Id
#GeneratedValue(strategy=GenerationType.IDENTITY)
private long reportId;
private long viewId;
private long startYear;
private long startMonth;
private long endYear;
private long endMonth;
#JsonManagedReference
#OneToOne(cascade = CascadeType.ALL)
#JoinColumn(name="data_id", referencedColumnName = "dataId")
private AnalyticsData data;
#JsonManagedReference
#OneToOne(cascade = CascadeType.ALL)
#JoinColumn(name="column_header_id", referencedColumnName = "columnHeaderId")
private AnalyticsColumnHeader columnHeader;
}
Above are the two top level entities. Either yearly or monthly reports are generated.
Below are the further nestings :
#Entity
#Table(name="report_data")
public class AnalyticsData
{
#Id
#GeneratedValue(strategy=GenerationType.IDENTITY)
private long dataId;
#JsonProperty
private boolean isDataGolden;
private long rowCount;
#JsonManagedReference
#OneToMany(mappedBy = "maximums",cascade=CascadeType.ALL)
private List<AnalyticsValue> maximums = new ArrayList<>();
#JsonManagedReference
#OneToMany(mappedBy = "minimums",cascade=CascadeType.ALL)
private List<AnalyticsValue> minimums = new ArrayList<>();
#JsonManagedReference
#OneToMany(mappedBy = "totals",cascade=CascadeType.ALL)
private List<AnalyticsValue> totals = new ArrayList<>();
#JsonManagedReference
#OneToMany(mappedBy = "analyticsData",cascade=CascadeType.ALL)
private List<AnalyticsRow> rows = new ArrayList<>();
#JsonBackReference
#OneToOne(mappedBy="data")
private AnalyticsReportMonthly analyticsReportMonthly;
#JsonBackReference
#OneToOne(mappedBy="data")
private AnalyticsReportYearly analyticsReportYearly;
getIsDataGolden() ; setIsDataGolden()
}
#Entity
#Table(name="report_column_header")
public class AnalyticsColumnHeader
{
#Id
#GeneratedValue(strategy=GenerationType.IDENTITY)
private long columnHeaderId;
#ElementCollection
#CollectionTable(name="column_header_dimensions",joinColumns=#JoinColumn(name="column_header_id"))
#Column(name="header_dimension")
private List<String> dimensions = new ArrayList<String>();
#JsonManagedReference
#OneToOne(cascade = CascadeType.ALL)
#JoinColumn(name = "metric_header_id", referencedColumnName = "metricHeaderId")
private AnalyticsMetricHeader metricHeader;
#JsonBackReference
#OneToOne(mappedBy = "columnHeader")
private AnalyticsReportYearly analyticsReportYearly;
#JsonBackReference
#OneToOne(mappedBy = "columnHeader")
private AnalyticsReportMonthly analyticsReportMonthly;
}
Below are the further nested entities for AnalyticsData:
#Entity
#Table(name="report_data_values")
public class AnalyticsValue
{
#Id
#GeneratedValue(strategy=GenerationType.IDENTITY)
private long valueId;
#ElementCollection
#CollectionTable(name="data_values",joinColumns=#JoinColumn(name="data_value_id"))
#Column(name="data_value")
private List<String> values = new ArrayList<String>();
#JsonBackReference
#ManyToOne(fetch=FetchType.LAZY)
#JoinColumn(name="data_maximums_id")
private AnalyticsData maximums;
#JsonBackReference
#ManyToOne(fetch=FetchType.LAZY)
#JoinColumn(name="data_minimums_id")
private AnalyticsData minimums;
#JsonBackReference
#ManyToOne(fetch=FetchType.LAZY)
#JoinColumn(name="data_totals_id")
private AnalyticsData totals;
#JsonBackReference
#ManyToOne(fetch=FetchType.LAZY)
#JoinColumn(name="row_id")
private AnalyticsRow analyticsRow;
}
#Entity
#Table(name="report_row")
public class AnalyticsRow
{
#Id
#GeneratedValue(strategy=GenerationType.IDENTITY)
private long rowId;
#ElementCollection
#CollectionTable(name="row_dimensions",joinColumns=#JoinColumn(name="row_id"))
#Column(name="row_dimension")
private List<String> dimensions = new ArrayList<String>();
#JsonManagedReference
#OneToMany(mappedBy = "analyticsRow",cascade=CascadeType.ALL)
private List<AnalyticsValue> metrics = new ArrayList<>();
#JsonBackReference
#ManyToOne(fetch=FetchType.LAZY)
#JoinColumn(name="data_id")
private AnalyticsData analyticsData;
}
Below the nesting for AnalyticsColumnHeader :
#Entity
#Table(name="report_metric_header")
public class AnalyticsMetricHeader
{
#Id
#GeneratedValue(strategy=GenerationType.IDENTITY)
private long metricHeaderId;
#JsonManagedReference
#OneToMany(mappedBy = "analyticsMetricHeader",cascade=CascadeType.ALL)
private List<AnalyticsMetricHeaderEntry> metricHeaderEntries = new ArrayList<>();
#JsonBackReference
#OneToOne(mappedBy = "metricHeader")
private AnalyticsColumnHeader analyticsColumnHeader;
}
#Entity
#Table(name="report_metric_header_entry")
public class AnalyticsMetricHeaderEntry
{
#Id
#GeneratedValue(strategy=GenerationType.IDENTITY)
private long metricHeaderEntryId;
private String name;
private String type;
#JsonBackReference
#ManyToOne(fetch=FetchType.LAZY)
#JoinColumn(name="METRIC_HEADER_ID")
private AnalyticsMetricHeader analyticsMetricHeader;
}
All of the tables have data except 'report_data_values'(Entity:AnalyticsValue), where it has the value_id auto-generated values. But row_id,data_maximums_id,data_minimums_id,data_totals_id are all NULL.
Below is the JSON that I am supposed to store :

}
}
These are the relevant details.
Note : I have been getting '415 Unsupported Media Type' because I added '#JsonManagedReference' and '#JsonBackReference'. I have added those because for a previous project I couldn't retrieve the JSON from the front end.
But now I am just trying to send the above JSON, so I could remove those annotations. Before adding those annotations, it saved successfully but I the values are NULL as I mentioned above.
Please help. Thanks in advance.
