Spring boot datasource lazy initialization

Question

@Lazy annotation not working on datasource configuration. This datasource autowired into prototype scoped bean, but datasource initialize on startup eager. In stack tracei see call from TomcatServletWebServerFactory .

@Configuration
@Lazy
public class MsSqlMppvConfig {
@Bean
@ConfigurationProperties("spring.mppvdatasource")
public DataSourceProperties mppvDataSourceProperties() {
    return new DataSourceProperties();
}

@Bean
@Lazy
@Qualifier("mppvdatasource")
@ConfigurationProperties("spring.mppvdatasource.hikari")
public DataSource mppvDataSource() {
    return mppvDataSourceProperties().initializeDataSourceBuilder().build();
}


@Bean(name = "tm_mppvdatasource")
@Autowired
DataSourceTransactionManager tm(@Qualifier("mppvdatasource") DataSource datasource) {
    return new DataSourceTransactionManager(datasource);
}}

 @Autowired
    @Qualifier("mppvdatasource")
    @Lazy
    DataSource mppvDs;

Maybe problem in @Qualifier annotation?

Had the same issue when importing spring-boot-starter-jdbc . Had to change it to just use spring-jdbc
