When I'm creating two entities in a single database, it shows me this error. The program works fine when the other table I want to add is not there. Of course it should not give any errors as there is no conceptual flaw. I just can't happen to find the cause of this error. 

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in class path resource [org/springframework/boot/autoconfigure/orm/jpa/HibernateJpaAutoConfiguration.class]: Invocation of init method failed; nested exception is javax.persistence.PersistenceException: [PersistenceUnit: default] Unable to build Hibernate SessionFactory

  • Have you checked this? `Caused by: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'to varchar(255), to_number varchar(255), primary key (smid))' ` – harshavmb May 27 '17 at 10:10
  • I don't understand the meaning of it. I used @Entity annotation, just like I used in previous table. What could cause this error? – Pranav Sinha May 27 '17 at 10:19
  • Can you paste the class which has been marked with `@Entity`? – harshavmb May 27 '17 at 10:21
  • maybe I got it. I should not have used variables like "to". I'll try rectifying it. Thanks for pointing it out. – Pranav Sinha May 27 '17 at 10:23
  • `package com.example.sent; import javax.persistence.Column; import javax.persistence.Entity; import javax.persistence.GeneratedValue; import javax.persistence.GenerationType; import javax.persistence.Id; import javax.persistence.Table; @Entity @Table(name="sent") public class SentMessagesEntity { @Id @GeneratedValue(strategy = GenerationType.AUTO) @Column(name = "smid") private long smid; @Column(name = "to") private String to; @Column(name = "to_number") private String toNumber; @Column(name = "message") private String message;` – Pranav Sinha May 27 '17 at 10:24
  • `//getters and setters public long getSmid() { return smid; } public void setSmid(long smid) { this.smid = smid; } public String getTo() { return to; } public void setTo(String to) { this.to = to; } public String getToNumber() { return toNumber; } public void setToNumber(String toNumber) { this.toNumber = toNumber; } public String getMessage() { return message; } public void setMessage(String message) { this.message = message; } } ` – Pranav Sinha May 27 '17 at 10:24
  • After I renamed String to; to String receiver; New error checkpoint achieved LOL `Description: Field smServ in com.example.contacts.ContactsController required a bean of type 'com.example.sent.SentMessagesService' that could not be found. Action: Consider defining a bean of type 'com.example.sent.SentMessagesService' in your configuration. ` – Pranav Sinha May 27 '17 at 10:26
  • So, how are you injecting object of `SentMessagesService` in `ContactsController` ? – harshavmb May 27 '17 at 10:29
  • I have created it using @Autowired SentMessagesService smServ; then calling function of SentMessagesService. – Pranav Sinha May 27 '17 at 10:37
  • Can you paste both the classes? – harshavmb May 27 '17 at 10:37
  • Now after your help, I overcame that error. For that I referred to this link: https://stackoverflow.com/questions/40384056/consider-defining-a-bean-of-type-package-in-your-configuration-spring-boot and used @EntityScan so now it scans all my entities. Now only problem which remains is it shows can not create bean of SentMessageServices. Any suggestions? – Pranav Sinha May 27 '17 at 10:38
  • Can you paste both the classes `SentMessagesService` and `ContactsController` ? – harshavmb May 27 '17 at 10:39
  • Is there any option to attach files, cuz it shows over 1000 characters exceeded. – Pranav Sinha May 27 '17 at 10:40
  • paste on https://pastebin.com/ and share the link – harshavmb May 27 '17 at 10:41
  • ContactsController.java https://pastebin.com/T36nzeKU – Pranav Sinha May 27 '17 at 10:44
  • SentMessagesService.java https://pastebin.com/er75aLaG – Pranav Sinha May 27 '17 at 10:45
  • okay can you add `@Service` annotation on `SentMessagesService` class and try? – harshavmb May 27 '17 at 10:46
  • bingo! oops how can i miss this annotation. Thanks a lot sir. Now its smooth and fine. So since this question is answered how can i close it? – Pranav Sinha May 27 '17 at 10:48
  • let me add as an answer. Then you can mark it as an answer. – harshavmb May 27 '17 at 10:48
  • Good that you fixed this yourself ...:) – harshavmb May 27 '17 at 10:57

The below error from the stack trace says :

Caused by: org.hibernate.tool.schema.spi.SchemaManagementException: Unable to execute schema management to JDBC target [create table sent_messages (smid bigint not null auto_increment, message varchar(255), to varchar(255), to_number varchar(255), primary key (smid))]

It indicates your Entity class has some problem, I'm glad that you did by yourself as you said it is fixed by renaming the member variables in Sent class and adding @EntityScan annotation to Application class.

Regarding the below error.

Description: Field smServ in com.example.contacts.ContactsController required a bean of type 'com.example.sent.SentMessagesService' that could not be found. Action: Consider defining a bean of type 'com.example.sent.SentMessagesService' in your configuration.

To inject the instance of SentMessagesService, you ought to add @Service annotation on SentMessagesService so that spring container creates bean of type 'com.example.sent.SentMessagesService'
