After upgrading to Spring Boot 3 / Hibernate 6, I am getting exceptions during Spring application / test startup.
java.lang.IllegalStateException: Failed to load ApplicationContext for [WebMergedContextConfiguration#15ec3c0c testClass = ....
Caused by: jakarta.persistence.PersistenceException: [PersistenceUnit: default] Unable to build Hibernate SessionFactory; nested exception is java.lang.IllegalArgumentException: Named type [interface java.util.List] did not implement BasicType nor UserType
Problem can be traced / debugged down to a List<String> entity property, which is using an AttributeConverter for storing it as a comma-separated string in the (MySQL) DB (TEXT field).
The converter:
#Converter
class StringListToStringConverter : AttributeConverter<List<String>, String> {
....
}
The entity:
#MappedSuperclass
abstract class MyInstance<T>(
...
#Column(name = "iface_ids", columnDefinition = "TEXT")
#Convert(converter = StringListToStringConverter::class)
var interfaceIds: List<String> = emptyList()
...
)
This has been working nicely before with Spring Boot 2.7.x / Hibernate 5.x.
Do you think there is another solution than writing a custom type (and thus removing/replacing the AttributeConverter) in this case?
Kind Regards,
dom
Expecting it to actually work OOTB, the AttributeConverter solution looks so clean&simple for this purpose compared to a custom type implementation that I don't really want to change that.

I'm trying to use Spring data JDBC with Query DSL in Kotlin.
This is my repository
#Repository
interface UserRepository : PagingAndSortingRepository<User, Int>, QuerydslPredicateExecutor<User> {}
My entity is a simple data object
#Entity
#Table(name = "user")
data class User(
#Id
#GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "user_id_seq")
#SequenceGenerator(name = "user_id_seq", sequenceName = "user_id_seq", allocationSize = 1)
val id: Int? = null,
val name: String,
val surname: String)
I've added these lines to my build.gradle
implementation("com.querydsl:querydsl-sql-spring:4.4.0") {
exclude group: 'joda-time', module: 'joda-time'
}
kapt "com.querydsl:querydsl-apt:4.4.0:jpa"
I've added the #EnableJdbcrepositories annotation in my Spring application
But when I try to start my application I get this error:
Unsatisfied dependency expressed through constructor parameter 1; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userRepository' defined in my.tests.querydsl.repositories.UserRepository defined in #EnableJdbcRepositories declared on
JdbcRepositoriesRegistrar.EnableJdbcRepositoriesConfiguration: Invocation of init method failed; nested exception is org.springframework.data.repository.query.QueryCreationException: Could not create query for public abstract long org.springframework.data.querydsl.QuerydslPredicateExecutor.count(com.querydsl.core.types.Predicate)! Reason: No property count found for type User!
I tried also to remove #EnableJdbcrepositories annotation but the error persists.
What I'm doing wrong? I'm missing some dependency?
Thanks
Infobip Spring Data Querydsl provides QuerydslPredicateExecutor fragment support for Spring Data JDBC (among other things).
With it, UserRepository definition should work as is defined, check out the module README.md JDBC section for details.
If you need SQLQuery, SQLUpdateClause or delete with Predicate support don't miss the QuerydslJdbcFragment.
The Spring-Data book says that only Spring Data JPA and MongoDB support QuerydslPredicateExecutor
I moved an entity which worked in JEE wildfly to quarkus:
#Entity
#Getter
#Setter
public class Item {
#Column(name = "archived")
private OffsetDateTime archived;
public boolean isArchived() {
return archived != null;
}
}
After running in dev-mode, I get this error:
Caused by: org.hibernate.MappingException:
In trying to locate getter for property [archived],
Class [com.Item]

I understand the error but I dont know why does this hibernate mapping work in wildfly and not in quarkus? As I declared jpa field access instead of jpa property access, hibernate should see the isArchived() automatically as transient.
Or does quarkus compiles all these field-injections to property-injections?
Quarkus generates a getter for the archived field.
Here Hibernate complains that you have two accessors for the archived field: isArchived() and getArchived().
This is an Hibernate issue/limitation, nothing specific to Quarkus.
I think the best is to rename your isArchived() method as Hibernate don't know which method to use to retrieve the value of the archivedfield. And if you add #Transient to your isArchived() method it could (depending on wich method it get first) handle your field as transient.
Here is my simple bean
#Data
#NoArgsConstructor
#AllArgsConstructor
#Builder
public class Foo {
private String firstName;
private String lastName;
public String getFullName(){
return firstName + lastName;
}
}
when this object gets serialized in Spring-boot controller with Jackson,
I get the following error

Here is the requestBody that I sent
{"firstName": "foo",
"lastName: null
}
Is Jackson trying to serialize fullName property ? but I have no such field declared. is this expected behavior? I am unable to find documentation that supports this behavior.
Thanks
Your guess is right, Jackson is trying to find the field name by its getter method, which it cannot find. And hence NPE.
Different solutions
use #JsonIgnore on the getFullName method.
you can disable this feature by setting this property in spring boot application.properties file
spring.jackson.mapper.use-getters-as-setters=false
If you wish to do it with the java code (If not using spring boot), you can do it with a bean declaration like this
#Bean
public Jackson2ObjectMapperBuilder objectMapperBuilder() {
Jackson2ObjectMapperBuilder builder = new Jackson2ObjectMapperBuilder();
builder.featuresToDisable(MapperFeature.USE_GETTERS_AS_SETTERS);
return builder;
}
I have a Spring Batch Job that defines a JdbcPagingItemReader with a BeanPropertyRowMapper :
JdbcPagingItemReader<RawNotice> reader = new JdbcPagingItemReader<>();
final SqlPagingQueryProviderFactoryBean sqlPagingQueryProviderFactoryBean = new SqlPagingQueryProviderFactoryBean();
sqlPagingQueryProviderFactoryBean.setDataSource(dataSource);
sqlPagingQueryProviderFactoryBean.setSelectClause("select *");
sqlPagingQueryProviderFactoryBean.setFromClause("from a_table");
sqlPagingQueryProviderFactoryBean.setWhereClause("state = :state");
sqlPagingQueryProviderFactoryBean.setSortKey("id");
Map<String, Object> parameters = new HashMap<>();
parameters.put("state", "interesting_state");
reader.setQueryProvider(sqlPagingQueryProviderFactoryBean.getObject());
reader.setDataSource(dataSource);
reader.setPageSize(10);
// The line below is the interesting one
reader.setRowMapper(new BeanPropertyRowMapper<>(MyEntity.class));
reader.setParameterValues(parameters);
return reader;
This used to work fine, but since we upgraded to spring boot 1.4 and spring cloud Camden, it throws an exception :
org.springframework.beans.ConversionNotSupportedException: Failed to convert property value of type [java.sql.Timestamp] to required type [org.joda.time.LocalDateTime] for property 'ADateColumn'; nested exception is java.lang.IllegalStateException: Cannot convert value of type [java.sql.Timestamp] to required type [org.joda.time.LocalDateTime] for property 'ADateColumn': no matching editors or conversion strategy found
The column ADateColumn is declared as a Joda LocalDateTime and stored as a java.sql.Timestamp in the database.
I'm quite aware I could add my own joda converters to the BeanPropertyRawMapper conversionService for example, or create a PropertyEditor that understands Java LocalDateTime, but that looks rather like a configuration problem, like something isn't being registered right.
Anybody with a solution/suggestion to fix this problem ?
Thanks !
This is the part of the entity that poses problem :
#Entity
#EqualsAndHashCode(of = { "..." })
#ToString(of = { .... })
public class MyEntity {
#Getter
#Setter
#Id
#GeneratedValue
private Long id;
#Getter
#Version
#Column(nullable = false)
private int version;
//<--- snip --->
#Getter
#Setter
#Type(type = "org.jadira.usertype.dateandtime.joda.PersistentLocalDateTime")
private LocalDateTime aDateColumn;
}
Hibernate is version 4.3.11.Final
JPA is version 2.1 with Hibernate Entity Manager 4.3.11.Final
So I finally ended up creating my own BeanPropertyRowMapper with custom Joda converters :/
Now that I found how to use converters in an HTML SELECT in Spring Roo, I am trying to do the same in a list.
I managed to register a Converter in my ApplicationConversionServiceFactoryBean, but now I need to use it as well when displaying a list of my envities. I have the following entity :
#RooJavaBean
#RooToString
#RooEntity
public class Environment {
#NotNull
#Size(min = 2, max = 30)
private String name;
#ManyToOne
private Application application;
}
When displaying it as a list in the generated MVC, it looks like the application is displayed as a toString() and not using the registered converter.
What am I missing ?
You need to push-in refactor the Roo generated converter method to the application conversion factory bean.
Sometimes, by default toString() method is used for the conversion.
Alternatively, you can try pushing in and overriding the toString() method within the entity itself. You will have to remove the #RooToString annotation while doing this.
Cheers!!!
