i do not understand what is happening , i launched my application as a spring boot application and tried man of those different queries but i still get the same result , for idea my database and apache server are active and working fine and the my repositories working fine too , just the urls none worked for me!
here my application properties file:
#Server configuration
server.servlet.context-path=/SpringMVC
spring.mvc.servlet.path=/servlet
server.port=8081
### DATABASE ###
#spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/timesheet?useUnicode=true&useJDBCCo
spring.datasource.username=root
spring.datasource.password=
### JPA / HIBERNATE ###
spring.jpa.show-sql=true
spring.jpa.hibernate.ddl-auto=update
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQL5Dialect
#Web configuration
spring.mvc.view.prefix=/views/
spring.mvc.view.suffix=.jsp
#logging configuration
logging.level.tn.esprit.service=debug
logging.level.tn.esprit.repository=warn
logging.level.root=INFO
logging.pattern.console=%d{yyyy-MM-dd HH:mm:ss} - %-5level - %logger{36} - %msg%n
logging.file=C:\logs\springboot.log
what am i missing???? why postman and my browser can not catch the queries?

Answer 1

You should add #RequestMapping annotation on top of your class and this parameter should be "/SpringMVC/servlet/{function extension}". For this function "aaa" as you show.
import java.util.List;
#SpringBootApplication(scanBasePackages={"tn.esprit"})
#RestController
#RequestMapping("/SpringMVC/servlet")
public class RestControlEmploye {
#Autowired
IEmployeService empService;
#Autowired
IEntrepriseService entService;
#RequestMapping(value="/aaa", method= RequestMethod.GET, produces = "application/json; charset=utf-8")
public List<String> getAllEmployeNamesJPQL() {
List<String> list = empService.getAllEmployeNamesJPQL();
return list;
}
}
