Spring Boot wont start Tomcat - spring-boot

I am new in spring boot framework. I tried a simple scratch application but my embedded tomcat wont startup. Also i downloaded source code from spring boot initialize, same application is running smoothly in another system but giving error in my system.

Running SQL scripts on startup with spring boot and h2 memory database

I have a spring-boot application where i'm running a h2 memory database, however I can't seem to run SQL scripts when starting the app. I want to run a script to create a couple of tables.
This script works fine when I run it manually, but I want to run it automatically on startup.
I have understood that the script should be ran automatically when put in the src/main/resources directory, which is also the classpath.
I found this Stackoverflow question which seems to contain all sorts of different answers, however none of them seem to work for me.
This is my pom.xml :

This is how my application.properties looks like :
spring.h2.console.enabled=true
spring.datasource.url=jdbc:h2:mem:testdb
spring.datasource.driverClassName=org.h2.Driver
spring.datasource.username=admin
spring.datasource.password=admin
spring.jpa.database-platform=org.hibernate.dialect.H2Dialect
spring.jpa.hibernate.ddl-auto=none
I tried to configure my application.properties in a couple of ways that were listed:
//Configuration 1
spring.datasource.schema=classpath:data.sql
//Configuration 2
spring.sql.init.schema-locations=classpath:data.sql
//Configuration 3
spring.datasource.data=classpath:data.sql
//Configuration 4
spring.sql.init.data-locations=classpath:data.sql
None of them worked, I also tried to configure a DataSource Bean, which seemed to have done something different, since the logs didn't show h2 memory database starting up before, now the logs show this:

The DataSource Bean :

dataSource.setUrl("jdbc:h2:mem:testdb");
dataSource.setUsername("admin");
dataSource.setPassword("admin");
// schema init
Resource initSchema = new ClassPathResource("data.sql");
DatabasePopulator databasePopulator = new ResourceDatabasePopulator(initSchema);
DatabasePopulatorUtils.execute(databasePopulator, dataSource);
return dataSource;
}
What am I missing here? Thanks!
EDIT I fixed the issue:
I found this post on github and it seemed relevant since my hikariPool wasn't starting up, I checked one of the answers where you configure the hikaripool as a bean, like this :
#Bean
public HikariDataSource createHikariConfig() {
HikariConfig hikariConfig = new HikariConfig();
hikariConfig.setDriverClassName("org.h2.Driver");
hikariConfig.setJdbcUrl("jdbc:h2:mem:testdb");
hikariConfig.setUsername("admin");
hikariConfig.setPassword("admin");
return new HikariDataSource(hikariConfig);
}
This made the hikariPool startup and execute the schema.sql script file under my src/main/resources, and now it is working.
You've disabled schema generation with
spring.jpa.hibernate.ddl-auto=none
Set it to create and it should work with the default schema.sql or import.sql
For reference, these are the possible values you can set it to:
none: No action will be performed
create-only: Database creation will be generated
drop: Database dropping will be generated
create: Database dropping will be generated followed by database creation.
create-drop: Drop the schema and recreate it on SessionFactory startup. Additionally, drop the schema on SessionFactory shutdown
validate: Validate the database schema
update: Update the database schema

Most probably you are using incompatible modules. This is also what the error message says:
Correct the classpath of your application so that it contains a
single, compatible version of
org.springframework.web.servlet.config.annotation.ResourceHandlerRegistration
In order to fix this go to https://start.spring.io/ and generate a project based on your needs. For an "MVC project" you only need spring-boot-starter-parent and spring-boot-starter-web; you definitely should not bring in webmvc, here's an example pom:

Spring boot:connection oracle database

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.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
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

You are missing spring-boot-starter-web artifact. Artifact contains tells spring boot to scan the package (in which main method is present) and all his subpackage for configuration, components and controller. Since this artifact is missing, spring doesn’t register your controller and throws 404-Not found.
