Spring boot:connection oracle database - spring-boot

Question

i'am using spring boot with oracle V11.2.0.4.0 database to develop a microservice,
But my pringBootApplication failed to run due to this following error:

here is my application.properties
spring.jpa.hibernate.ddl-auto=update
spring.datasource.url= jdbc:oracle:thin:#Oracle-dev.xxx.xx.xx:1521:LBVT
spring.datasource.username=xxxx
spring.datasource.password=xxx!
spring.datasource.driver-class-name=oracle.jdbc.OracleDriver
spring.jpa.show-sql=true
Someone have an idea about this issue ?
I already download the ojdbc6.jar and use maven command to install the driver
any clue will be helpful

Answer 1

The problem is due to MAX_VALUE to large in All_sequence,
That's why i had this error
java.sql.SQLException: Numeric Overflow
I fixed this issue as follows:
I created a Custom class which extends Oracle10gDialect and redefined MIN_VALUE, MAX_VALUE in ALL_SEQUENCES,
Here is my class
package ibbl.lu.microservice_lims.config;
import org.hibernate.dialect.Oracle10gDialect;
public class CustomOracleDialect extends Oracle10gDialect {
#Override
public String getQuerySequencesString() {
return "SELECT SEQUENCE_OWNER, SEQUENCE_NAME,
greatest(MIN_VALUE,-9223372036854775807) MIN_VALUE,\n" +
"Least(MAX_VALUE, 9223372036854775808) MAX_VALUE,
INCREMENT_BY,CYCLE_FLAG, ORDER_FLAG, CACHE_SIZE,\n" +
"Least(greatest(LAST_NUMBER, -9223372036854775807),
9223372036854775808) LAST_NUMBER from ALL_SEQUENCES";
}
}
In the application.properties file referred to a dialect implementation
spring.jpa.properties.hibernate.dialect=ibbl.lu.microservice_lims.config.CustomOracleDialect
