Initialization order issue -------------------------- Key: TEIIDSB-160 URL: https://issues.redhat.com/browse/TEIIDSB-160 Project: Teiid Spring Boot Issue Type: Bug Components: core Reporter: Steven Hawkins Assignee: Steven Hawkins Priority: Major Fix For: 1.4.0, 1.3.1 Original Estimate: 2 hours Remaining Estimate: 2 hours In working with the infinispan translator there is a situation where defining a project that has no relational sources, but uses infinispan and a rest source on startup gives: {code} Description: The bean 'dataSource', defined in class path resource [org/teiid/spring/autoconfigure/TeiidAutoConfiguration.class], could not be registered. A bean with that name has already been defined in class path resource [org/springframework/boot/autoconfigure/jdbc/DataSourceConfiguration$Tomcat.class] and overriding is disabled. Action: Consider renaming one of the beans or enabling overriding by setting spring.main.allow-bean-definition-overriding=true {code} Our starter has a reference to tomcat-jdbc, so that will always be in the classpath making that DataSourceConfiguration eligible. The best solution seems to be for the TeiidAutoConfiguration to be marked with {code}@AutoConfigureBefore({ DataSourceAutoConfiguration.class }){code} so that it will install the primary datasource bean first.
