@componentscan @enableautoconfiguration @propertysource(value = { "file:/users/documents/workspace/application.properties" }) public class application extends springbootservletinitializer{ public static void main(string[] args) { configurableapplicationcontext context = springapplication.run(application.class, args); }

in case gives while deploying:

org.springframework.beans.factory.nosuchbeandefinitionexception: no qualifying bean of type [org.springframework.jdbc.core.jdbctemplate] found dependency:

not able find right way externalize application properties file

i tried autowiring environment variable correctly loaded need manually define beans

@bean public jdbctemplate datasource() { string driverclassname = env .getproperty("spring.datasource.driverclassname"); string dsurl = env.getproperty("spring.datasource.url"); string username = env.getproperty("spring.datasource.username"); string password = env.getproperty("spring.datasource.password"); //datasource datasource = new simpledriverdatasource(new driverclassname, dsurl, username, password); jdbctemplate jdbc = new jdbctemplate(datasource); homecoming jdbc; }

this deploys without throwing error not responding.

there no need define using @propertysource annotation. should utilize spring.config.location property set application.properties location. property can set illustration in command line:

java -jar myapp.jar --spring.config.location=/users/documents/workspace/

spring tomcat deployment spring-boot
