mysql - Spring 与 mySql

Question

我的伙伴有相同的代码，但我是唯一遇到此问题的人。我有相同的 mySql 和 Spring 版本。这是我得到的异常:

org.springframework.beans.factory.BeanCreationException: 
  Error creating bean with name 'dataBaseUsage': Invocation of init method failed; 
  nested exception is 
  org.springframework.dao.InvalidDataAccessResourceUsageException: 
  could not execute statement; SQL [n/a]; nested exception is
  org.hibernate.exception.SQLGrammarException: could not execute statement

Caused by: org.springframework.dao.InvalidDataAccessResourceUsageException: 
could not execute statement; SQL [n/a]; nested exception is 
org.hibernate.exception.SQLGrammarException: could not execute statement

Caused by: org.hibernate.exception.SQLGrammarException: 
could not execute statement

Caused by: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: 
Unknown column 'roles' in 'field list'

DataBaseUsage是@Controller

谢谢

您只是在数据库表中没有列roles。您应该更新您的数据库。您可以使用hibernate.hbm2ddl.auto=update。
