stacktrace

error - org.springframework.beans.factory.beancreationexception: error creating bean name 'jdbctemplate' defined in class path resource [org/springframework/boot/autoconfigure/jdbc/datasourceautoconfiguration$jdbctemplateconfiguration.class]: bean instantiation via factory method failed; nested exception org.springframework.beans.beaninstantiationexception: failed instantiate [org.springframework.jdbc.core.jdbctemplate]: factory method 'jdbctemplate' threw exception; nested exception java.lang.illegalargumentexception: property 'datasource' required 

spring boot docs describe 3 spring boot mechanisms how configure datasource bean:

1. embedded database -> add embedded db engine classpath
2. standard sql data source -> configure jdbc access in configuration file
3. jndi db access -> configured via configuration file

additionally can configure datasource bean explicitly standard spring ioc mechanisms.

your error indicates non of these constructs defining datasource bean exist in application.
