通过Spring MVC从Oracle数据库获取自动增加的id（主键）

Question

我正在使用触发器在Oracle数据库中自动使表的id列自动递增。

这是我的Spring控制器中的代码，

@RequestMapping("/ssuForm/create")
@ResponseStatus(HttpStatus.OK)
@ResponseBody
public UmkeiBusinessInfo createSsuForm(@RequestBody UmkeiBusinessInfo umkeiSsu) {

    UmkeiBusinessInfo createSsuForm = umkeiBusinessInfoService.create(umkeiSsu);
    System.out.println(createSsuForm);
    return createSsuForm;
}

如何使用System.out.println查看返回的内容，我看不到列出的id。其他一切都做了。

这里是日志，

|Nexus|Wed Apr 13 00:00:00 SGT 2016|Nexus Street|NexusCity|04|null|80000|0108808550|nexus@nexi.com|1|A|2|P1|B10A218|Sun Apr 03 10:40:28 SGT 2016|null||B10A218|1|0145283459|teniousd@yahoo.com|9|A08|00751A|null|null|null|null|null

请注意，它以Nexus开头，而不是ID。

下面是我的表格的代码片段，

编辑：

这是/ business / service / impl

中的代码

    @Override
public UmkeiBusinessInfo save(UmkeiBusinessInfo umkeiBusinessInfo) {
    return update(umkeiBusinessInfo) ;
}

@Override
public UmkeiBusinessInfo create(UmkeiBusinessInfo umkeiBusinessInfo) {
    UmkeiBusinessInfoEntity umkeiBusinessInfoEntity = umkeiBusinessInfoJpaRepository.findOne(umkeiBusinessInfo.getUbiId());
    if( umkeiBusinessInfoEntity != null ) {
        throw new IllegalStateException("already.exists");
    }
    umkeiBusinessInfoEntity = new UmkeiBusinessInfoEntity();
    umkeiBusinessInfoServiceMapper.mapUmkeiBusinessInfoToUmkeiBusinessInfoEntity(umkeiBusinessInfo, umkeiBusinessInfoEntity);
    UmkeiBusinessInfoEntity umkeiBusinessInfoEntitySaved = umkeiBusinessInfoJpaRepository.save(umkeiBusinessInfoEntity);
    return umkeiBusinessInfoServiceMapper.mapUmkeiBusinessInfoEntityToUmkeiBusinessInfo(umkeiBusinessInfoEntitySaved);
}

@Override
public UmkeiBusinessInfo update(UmkeiBusinessInfo umkeiBusinessInfo) {
    UmkeiBusinessInfoEntity umkeiBusinessInfoEntity = umkeiBusinessInfoJpaRepository.findOne(umkeiBusinessInfo.getUbiId());
    umkeiBusinessInfoServiceMapper.mapUmkeiBusinessInfoToUmkeiBusinessInfoEntity(umkeiBusinessInfo, umkeiBusinessInfoEntity);
    UmkeiBusinessInfoEntity umkeiBusinessInfoEntitySaved = umkeiBusinessInfoJpaRepository.save(umkeiBusinessInfoEntity);
    return umkeiBusinessInfoServiceMapper.mapUmkeiBusinessInfoEntityToUmkeiBusinessInfo(umkeiBusinessInfoEntitySaved);
}

，这是实体部分，

//----------------------------------------------------------------------
// ENTITY PRIMARY KEY ( BASED ON A SINGLE FIELD )
//----------------------------------------------------------------------
@NotNull
@Size( min = 1, max = 20 )
private String ubiId;

//----------------------------------------------------------------------
// ENTITY DATA FIELDS 
//----------------------------------------------------------------------    
@Size( max = 100 )
private String ubiName;


private Date ubiStartDate;

@Size( max = 100 )
private String ubiAddress;

@Size( max = 64 )
private String ubiCity;

@Size( max = 10 )
private String ubiState;

@Size( max = 10 )
private String ubiCountry;

这里是JPA实体部分，

//----------------------------------------------------------------------
// ENTITY PRIMARY KEY ( BASED ON A SINGLE FIELD )
//----------------------------------------------------------------------
@Id
@Column(name="UBI_ID", nullable=false, length=20)
private String     ubiId        ;


//----------------------------------------------------------------------
// ENTITY DATA FIELDS 
//----------------------------------------------------------------------    
@Column(name="UBI_NAME", length=100)
private String     ubiName      ;

@Temporal(TemporalType.TIMESTAMP)
@Column(name="UBI_START_DATE")
private Date       ubiStartDate ;

@Column(name="UBI_ADDRESS", length=100)
private String     ubiAddress   ;

Answer 1

我刚刚开始工作。

首先，我需要在ORACLE中将数据类型更改为“Number”，然后将所有代码从String更改为BigDecimal。

然后添加Bunti提到的注释，

@GeneratedValue(strategy = GenerationType.SEQUENCE, generator="UMKEI_BUSINESS_INFO_SEQ1")
@SequenceGenerator(name="UMKEI_BUSINESS_INFO_SEQ1 ", sequenceName="UMKEI_BUSINESS_INFO_SEQ1", allocationSize=1) 

我将增量值传递给客户端。

之前由于dataType而无法正常工作。
