Question
I have Spring Boot web application. It's centered around RESTful approach. All configuration seems in place but for some reason MainController fails to handle request. It results in 404 error. How to fix it?
@Controller
public class MainController {
@Autowired
ParserService parserService;
@RequestMapping(value="/", method= RequestMethod.GET)
public @ResponseBody String displayStartPage(){
return "{hello}";
}
}
Application
@Configuration
@ComponentScan(basePackages = "")
@EnableAutoConfiguration
public class Application extends SpringBootServletInitializer{
public static void main(final String[] args) {
SpringApplication.run(Application.class, args);
}
@Override
protected final SpringApplicationBuilder configure(final SpringApplicationBuilder application) {
return application.sources(Application.class);
}
}
ParserController
@RestController
public class ParserController {
@Autowired
private ParserService parserService;
@Autowired
private RecordDao recordDao;
private static final Logger LOG = Logger.getLogger(ParserController.class);
@RequestMapping(value="/upload", method= RequestMethod.POST)
public @ResponseBody String fileUploadPage(
}
}
UPDATE
Seems like MySQL cannot be initialized by Spring....

UPDATE2
application.properties
# Database
spring.datasource.driverClassName = com.mysql.jdbc.Driver
spring.datasource.url = jdbc:mysql://localhost:3306/logparser
spring.datasource.username = root
spring.datasource.password = root
spring.jpa.database = MYSQL
spring.jpa.show-sql = true
# Hibernate
hibernate.dialect: org.hibernate.dialect.MySQL5Dialect
hibernate.show_sql: true
hibernate.hbm2ddl.auto: update
entitymanager.packagesToScan: /
UPDATE4
Seems lite controllers not responding eventhough @RequestMapping are set.
Why might it be?
PS. It occurs when I run Maven's lifecycle
test. When running in degub mode in IntelliJ there is no error outputted.
UPDATE5
Also I use this DAO as explained in tutorial....
public interface RecordDao extends CrudRepository<Record, Long> {
}

UPDATE6
I did changed my application properties. And tried every single combination but it refuses to work. ;(
Maven output:

Answer
Looks like the initial problem is with the auto-config.
If you don't need the datasource, simply remove it from the auto-config process:
@EnableAutoConfiguration(exclude={DataSourceAutoConfiguration.class})
Edit: If using @SpringBootApplication in your main class:
@SpringBootApplication(exclude={DataSourceAutoConfiguration.class})
