用test類測試service的save方法時,報錯如下:

2018-08-24 21:52:13,506 - could not read a hi value
com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Table ‘sell.hibernate_sequence‘ doesn‘t exist
    at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method)
    at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:
 
62)
    at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:45)
    at java.lang.reflect.Constructor.newInstance(Constructor.java:423)
    at com.mysql.jdbc.Util.handleNewInstance(Util.java:425)
    at com.mysql.jdbc.Util.getInstance(Util.java:408)
    at com.mysql.jdbc.SQLError.createSQLException(SQLError.java:
 
944)

後經過調查,原因是實體類的自增主鍵寫的有問題,

原寫法:

@GeneratedValue
    private Integer categoryId;

現寫法:

@GeneratedValue(strategy = GenerationType.IDENTITY) //設置主鍵生成模式為自增
    private Integer categoryId;

加上策略後,問題解決
