我正在尝试让我的应用程序通过Hibernate从我的Oracle数据库中检索结果。当我用webservice点击它时,我得到了一个奇怪的SQL语句(我将hibernate.show_sql设置为true)。我没有收到任何错误,但我也没有得到任何结果。 (我很擅长冬眠,并对任何反馈表示感谢。谢谢)
来自控制台:
INFO: Server startup in 5743 ms
Hibernate: select standards0_.STANDARD_CODE as STANDARD1_0_, standards0_.STANDARD_NAME as STANDARD2_0_, standards0_.STANDARD_TYPE as STANDARD3_0_ from STANDARDS standards0_
0
这是我的表格的样子:
STANDARDS Columns:
Column Name Type Size Primary Key Foreign Key Nullable Scale
STANDARD_CODE VARCHAR2 25 true N
STANDARD_NAME VARCHAR2 100 N
STANDARD_TYPE VARCHAR2 25 N
jdbc.properties:
jdbc.driverClassName=oracle.jdbc.OracleDriver
jdbc.url=jdbc:oracle:thin:@myurl:1521:mySID
jdbc.username=MYUSERNAME
jdbc.password=MYPASSWORD
