Spring 使用 Sybase 的数据 Jpa - UnimplementedOperationException
Spring Data Jpa with Sybase - UnimplementedOperationException
我发现将对象持久化到 Sybase 起诉 Spring Data JPA 存在问题。我看到的错误是
com.sybase.jdbc3.utils.UnimplementedOperationException:
The method com.sybase.jdbc3.jdbc.SybConnection.prepareStatement(String, int)
has not been completed and should not be called.
我已将其简化为带有 ID 和描述的实体对象，但仍然看到错误。
我的实体class是
@Entity
@Table(name = "tbl_bsc_region")
public class Region implements Serializable {
private static final long serialVersionUID = -7985499571755472582L;
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Column(name = "bsc_region_id")
private Long id;
@Column(name = "region_name")
private String regionName;
protected Region() {
// for JPA only
}
public Region(final String regionName) {
this.regionName = regionName;
}
/**
* Accessor method for id.
*
* @return value of id
*/
public Long getId() {
return this.id;
}
/**
* Modifier method for id.
*
* @param id
* the id to set
*/
public void setId(final Long id) {
this.id = id;
}
/**
* Accessor method for regionName.
*
* @return value of regionName
*/
public String getRegionName() {
return this.regionName;
}
/**
* Modifier method for regionName.
*
* @param regionName
* the regionName to set
*/
public void setRegionName(final String regionName) {
this.regionName = regionName;
}
}
我的测试是
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("/spring/application-test.xml")
public class RegionIntegrationTest {
@Autowired
RegionRepository repo;
/**

*/
@Test
public void testSave() throws Exception {
final Region region = new Region("CG Region");
this.repo.save(region);
}
