java.lang.IllegalArgumentException: Not a managed type: class

Question

I am creating Spring boot application with 2 different datasources. I have created configuration files for separate DB. Entities are in different package and Models are in different package for each database. When I run

mvn clean install

it creates database properly and all tables as well. But is always fails while creating repository. Below I am providing all necessary details:

Main class

@SpringBootApplication
@EnableAutoConfiguration
public class Demo {

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

Application.properties

spring.application.name= nyota-plateform
spring.jpa.database-platform=org.hibernate.dialect.MySQL5Dialect
spring.jpa.database= MYSQL
spring.jpa.generate-ddl= true
spring.jpa.hibernate.ddl-auto= update
spring.jpa.properties.hibernate.implicit_naming_strategy= org.hibernate.boot.model.naming.ImplicitNamingStrategyJpaCompliantImpl


spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.jdbc-url= jdbc:mysql://localhost:3306/DB1?useUnicode=true&createDatabaseIfNotExist=true&useSSL=false
spring.datasource.username= *
spring.datasource.password= *
spring.datasource.dbcp2.max-idle= 10000

authdb.datasource.driver-class-name=com.mysql.jdbc.Driver
authdb.datasource.jdbc-url= jdbc:mysql://localhost:3306/DB2?useUnicode=true&createDatabaseIfNotExist=true&useSSL=false
authdb.datasource.username= *
authdb.datasource.password= *
authdb.datasource.dbcp2.max-idle= 10000

Db1 configuration:

@Configuration
@EnableTransactionManagement
@EnableJpaRepositories(basePackages = { "com.test.demo.repo.db1" })
public class DatabaseConfiguration {

    @Primary
    @Bean(name = "dataSource")
    @ConfigurationProperties(prefix = "spring.datasource")
    public DataSource dataSource() {
        return DataSourceBuilder.create().build();
    }

    @Primary
    @Bean(name = "entityManagerFactory")
    public LocalContainerEntityManagerFactoryBean entityManagerFactory(EntityManagerFactoryBuilder builder,
            @Qualifier("dataSource") DataSource dataSource) {
        return builder.dataSource(dataSource).packages("com.test.demo.model.db1").persistenceUnit("main").build();
    }

    @Primary
    @Bean(name = "transactionManager")
    public PlatformTransactionManager transactionManager(
            @Qualifier("entityManagerFactory") EntityManagerFactory entityManagerFactory) {
        return new JpaTransactionManager(entityManagerFactory);
    }

}

DB2 configuration:

@Configuration
    @EnableTransactionManagement
    @EnableJpaRepositories(basePackages = { "com.test.demo.repo.db2" })
    public class DatabaseConfiguration {

    @Primary
    @Bean(name = "dataSource2")
    @ConfigurationProperties(prefix = "authdb.datasource")
    public DataSource dataSource() {
        return DataSourceBuilder.create().build();
    }

    @Bean(name = "entityManagerFactory2")
    public LocalContainerEntityManagerFactoryBean entityManagerFactory(EntityManagerFactoryBuilder builder,
            @Qualifier("dataSource2") DataSource dataSource) {
        return builder.dataSource(dataSource).packages("com.test.demo.model.db2").persistenceUnit("main").build();
    }

    @Bean(name = "transactionManager2")
    public PlatformTransactionManager transactionManager(
            @Qualifier("entityManagerFactory2") EntityManagerFactory entityManagerFactory) {
        return new JpaTransactionManager(entityManagerFactory);
    }
}

Db2 Model

@Entity
public class AuthUser {

    @Id
    @GeneratedValue
    private Long id;

    @Column
    private String name;

    @Column(nullable=false,unique=true)
    private String username;

    @Column(nullable=false)
    private String password;

    @Column(nullable=false)
    private String role;

    @Column
    private String uniqueId = UUID.randomUUID().toString();


    public AuthUser(String name, String username, String password, String role) {
        super();
        this.name = name;
        this.username = username;
        this.password = password;
        this.role = role;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    public Long getId() {
        return id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getUsername() {
        return username;
    }

    public void setUsername(String email) {
        this.username = email;
    }

    public String getRole() {
        return role;
    }

    public void setRole(String role) {
        this.role = role;
    }

    public String getUniqueId() {
        return uniqueId;
    }

    public void setUniqueId(String uniqueId) {
        this.uniqueId = uniqueId;
    }
}

Repository

@Repository
public interface AuthUserRepository extends JpaRepository<AuthUser, Long> {

    public AuthUser findByUsernameAndPassword(String email,String password);
}

Now error Log:

Can anyone help on this? What parameter I am missing or what I am doing wrong here? Thanks in advance!

@f1sh I am not sure it is same or not, but I tried ComponentScan , EntityScan, Component as well. But it doesn't work. — Jayesh Choudhary

I had a similar problem when using different datasources. Using the @Qualifier annotation solved it for me. In the configurations you could annotate your Beans with @Qualifier("DB1") and use them in your Repository with @Transactional(transactionManager="DB1").

Found solution to my problem, All I need to do is to update following line in Database configuration file.
From :

@EnableJpaRepositories(basePackages = { "com.test.demo.repo.db1" })

To :

@EnableJpaRepositories(entityManagerFactoryRef = "entityManagerFactory", transactionManagerRef = "transactionManager", basePackages = { "com.test.demo.repo.db1" })

Thanks for your help guys.
