Error when retrieving values from MS SQL using Hibernate

I've done a program where I have to retrieve the data from a table in MS SQL. I'm using Hibernate where AbtDebtbyCAN is an Entity class. The connection so far is fine but the only problem I'm facing is printing out data from MS SQL using Annotation Mapping. Debt is the name of the table(the name of the table is in lower case) which is to be mapped with. Below here is the result I want to print it out using Hibernate. Can anybody help me on how to achieve the fetching of data?
debt
id can bdrl_debt excess_ta_debt posting_ref debt_settlement_id debt_settlement_at debt_business_date

Not sure what types you are exactly using here, but at least DateTime is not a standard type that is supported by Hibernate. If Hibernate does not know about a type, it tries to flush the value in its serialized form as blob/byte[]. If you would use java.sql.Timestamp, java.util.Calendar or any other type that is supported by Hibernate out of the box, this should work properly.

Jooq CastException on Spring Boot context refreshed

when spring boot first startup, jooq works well.
but if i make change to code and after spring boot context refreshed,
then i stucked in trouble with class cast exception.
the problem is cast exception on same class.
my boot conf is :
#Autowired
private DataSource dataSource;
public ExecuteListener exceptionTransformer() {
return new DefaultExecuteListener() {
private static final long serialVersionUID = 1L;
#Override
public void exception(ExecuteContext context) {
SQLDialect dialect = context.configuration().dialect();
SQLExceptionTranslator translator = (dialect != null)
? new SQLErrorCodeSQLExceptionTranslator(dialect.name())
: new SQLStateSQLExceptionTranslator();
context.exception(
translator.translate("jOOQ", context.sql(), context.sqlException()));
}
};
}
#Primary
#Bean
public DefaultDSLContext dsl() {
return new DefaultDSLContext(configuration());
}
public DataSourceConnectionProvider connectionProvider() {
return new DataSourceConnectionProvider(new TransactionAwareDataSourceProxy(dataSource));
}
public DefaultConfiguration configuration() {
DefaultConfiguration configuration = new DefaultConfiguration();
configuration.set(connectionProvider());
configuration.set(new DefaultExecuteListenerProvider(exceptionTransformer()));
configuration.set(SQLDialect.MYSQL);
// #formatter:off
configuration.set(
new Settings()
.withExecuteLogging(true)
.withRenderFormatted(true)
);
// #formatter:on
configuration.set(SfmRecordMapperProviderFactory.newInstance().ignorePropertyNotFound().newProvider());
return configuration;
}
query code is :
User user = dsl.select()
.from(USER)
.where(USER.USER_ID.eq(id)).fetchOneInto(User.class);
admin.domain.User is:
#Data
public class User implements Serializable {
private static final long serialVersionUID = 1L;
private String userId;
#JsonIgnore
private String pswd;
private String name;
private String useYn;
private Timestamp registDatetime;
private Timestamp updateDatetime;
}
stack trace is :

what is my fault?

Do you have spring boot automatic restart enabled?
This look likes it, you could try:
to run without the devtools (https://docs.spring.io/spring-boot/docs/current/reference/html/using-boot-devtools.html#using-boot-devtools-restart-disable)
add the correct path to your live reload (
https://docs.spring.io/spring-boot/docs/current/reference/html/using-boot-devtools.html#using-boot-devtools-restart-additional-paths and https://docs.spring.io/spring-boot/docs/current/reference/html/using-boot-devtools.html#using-boot-devtools-customizing-classload )

MongoDB Cannot use a complex object as a key value Java

I'm implementing an object that represents a graph to be stored in a MongoDb. Here's the class definition:
#Document(collection = "mygraph")
public class MyGraph {
#Id
#JsonSerialize(using = ToStringSerializer.class)
public String id;
public Map<Instance, Set<Instance>> graph;
public String timestamp;
/**
* Add the default constructor
*/
public MyGraph() {
this.id = new ObjectId().toHexString();
this.graph = new LinkedHashMap<>();
DateFormat dateFormat = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");
this.timestamp = dateFormat.format(new Date());
}
/**
*
* #param instances
*/
public MyGraph(Set<Instance> instances) {
this.id = new ObjectId().toHexString();
this.graph = new LinkedHashMap<>();
DateFormat dateFormat = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");
this.timestamp = dateFormat.format(new Date());
/* Initialize the graph */
for (Instance instance : instances) {
this.graph.put(instance, new HashSet<>());
}
}
// get and set method are below
}
However I'm getting the following error:

How can I change my MappingMongoConverter to accomodate for that?

There's an open Improvement in Spring: Don't require Converters for Complex classes that are used as Ids.
Unfortunately, currently Spring team decided not to support it.
decided not to support it at all
EDIT
There's an open related issue Allow using complex types as Map keys that may include a fix later

I am not setting serviceBeginTime and serviceEndTime in my POST JSON currently. But this wasn't giving me a null pointer before I upgraded spring boot version.

Added a null check as that was the easiest.

Getting a JSON object returned in Java

I'm trying to get a JSON object displayed via an API, but I get a error message along with it.
Here is the method that I've written:
public MarketDataListLevel1 getMarketDataTicker() {
try {
MarketDataListLevel1 md = CS.getMarketDataTicker();
log.info(md.toString());
return md;
}
catch ( Exception e) {
e.printStackTrace();
return null;
}
}
Where CS is an object that processes the JSON data from a URL..
For some reason, when I call that method, I'm getting the precise output that I want, but I also get these additional error messages that follow it, and I'm unsure why. Any help would be appreciated.
