这是我的主课
@Configuration
@EnableAutoConfiguration
@ComponentScan
public class Application extends SpringBootServletInitializer {
public static void main(final String[] args) {
SpringApplication.run(Application.class, args);
}
}
这是我的 application.properties
#server.contextPath=/SpringBootExamples
server.port=8888
logging.file=F:/new-spring-boot/Test-Spring-Boot.log
# spring security configuration
security.user.name=admin
security.user.password=admin1
management.security.role=SUPERUSER
spring.data.jpa.repositories.enabled=true
spring.datasource.url= jdbc:mysql://localhost:3306/springbootdb
spring.datasource.username=root
spring.datasource.password=root
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.jpa.hibernate.ddl-auto=create-drop
这是我的 UserServiceImpl
@Service
public class UserServiceImpl implements UserService{
@Autowired
private UserRepository userRepo;
@Override
@Transactional
public void saveUser(MyUserEntity user) {
userRepo.save(user);
//testTransaction();
}
}
**这是我的 UserRepository **
**Here is my UserRepository **
@Repository
public interface UserRepository extends CrudRepository<MyUserEntity, Long>{
}
我遇到以下错误 java -jar target/example-spring-boot-rest-1.0-SNAPSHOT.war

推荐答案
我升级到
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.3.3.RELEASE</version>
</parent>
效果很好.但它真的很奇怪，因为它使用的是 1.0.1. 版本，直到一小时前.
It worked fine. But its really strange as it was working with version 1.0.1. also till one hour before.
