net.lecousin.reactive.data.relational.model.ModelAccessException: Unknown entity type

I have that error even though I already annotated the entity class with @Table(value="table_name") and entity class property with @Column(value="column_name") to be recognized as entity. Why the entity is didn't recognized by lc-spring-data-r2dbc? Can anyone help me to solve this problem? Thanks in advance!

Below is the entity.

package com.sg.atlas.infrastructure.model.entity;

import lombok.AllArgsConstructor;
import lombok.Builder;
import lombok.Data;
import lombok.NoArgsConstructor;
import org.springframework.data.annotation.Id;
import org.springframework.data.relational.core.mapping.Column;
import org.springframework.data.relational.core.mapping.Table;

import java.sql.Timestamp;

@Data
@AllArgsConstructor
@NoArgsConstructor
@Builder
@Table(value = "account")
public class Account {
    @Id
    private Long id;
    @Column
    private String name;
    @Column
    private String email;
    @Column
    private String password;
    @Column(value = "created_at")
    private Timestamp createdAt;
    @Column(value = "updated_at")
    private Timestamp updatedAt;
}

Below is the complete stack trace.

Do you have the init line in your main ?

LcReactiveDataRelationalInitializer.init();

Yes, I have. Below is the application class.

package com.sg.atlas;

import net.lecousin.reactive.data.relational.LcReactiveDataRelationalInitializer;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.context.properties.ConfigurationPropertiesScan;

@SpringBootApplication
@ConfigurationPropertiesScan("com.sg.atlas.infrastructure.property")
public class AtlasServiceApplication {

    public static void main(String[] args) {
        LcReactiveDataRelationalInitializer.init();
        SpringApplication.run(AtlasServiceApplication.class, args);
    }

}

This is the startup console log from the app run. It gives information that the lc-spring-data-r2dbc found 7 entity classes but when the repository method is called, why the lc-spring-data-r2dbc can't recognise it?

It may come from the Spring devtools restart feature, can you try to disable it and check if it works without it ?

Looks like a dependency version conflict, can you try to put the dependency io.r2dbc:r2dbc-spi:0.9.1.RELEASE at the top of your dependencies ?
For maven:

<dependency>
  <groupId>io.r2dbc</groupId>
  <artifactId>r2dbc-spi</artifactId>
  <version>0.9.1.RELEASE</version>
</dependency>

ok, the error is fixed now. how do you know the problem is dependency conflict? and, why classloaders from spring dev tools could make this lc-spring-data-r2dbc dependency not work as normal?

I will fix the version conflict by adding the version in the dependency management, because currently spring data depends on the previous r2dbc-spi version (0.8) while we already upgraded our drivers to the latest 0.9.1.RELEASE.

Regarding the spring devtools, it does not work because lc-spring-data-r2dbc needs to enhance entity classes at startup, but the devtools reload the original class in a different ClassLoader. I will have a look how we can support it.

The new release 0.10.1 should fix the 2 issues.
Could you try to upgrade and tell if it fixes it for your case ?

Already upgraded to 0.10.1 but still need to specify implementation 'io.r2dbc:r2dbc-spi:0.9.1.RELEASE' and runtimeOnly 'io.r2dbc:r2dbc-postgresql:0.9.1.RELEASE' in build.gradle dependencies. And, the classloader problem from spring devtools is fixed now.
