我有服务类，它作为单个事务执行两个db事务。如果发生异常，我想做一些其他数据库插入。我希望以上所有操作都是一次交易。
Follwing是服务类
package edu.unomaha.ist.bioinformatics.serviceimpl;
import org.apache.log4j.Logger;
import org.hibernate.exception.ConstraintViolationException;
import org.springframework.beans.factory.annotation.Autowired;
@Service
public class DbOPerationsImpl implements DbOperations {
static Logger log = Logger.getLogger(SequenceValidation.class.getName());
@Autowired
private SequencesRestRepository seqrepo;
@Autowired
private SequenceNamesRepo seqnamerepo;
@Transactional(propagation = Propagation.REQUIRED,noRollbackFor = Exception.class)
public void insertsequence(int dbid, String active, String sequence, String hash, int i3bio, int regid, int version,String genename) {
int seqid=0;
SequencesRest seqobj=null;
boolean isDuplicate=false;
try {
System.out.println("before insert");
try{
seqrepo.insertsequence(dbid,active,sequence , hash, i3bio, regid, version);
}
catch(DataIntegrityViolationException ex){
isDuplicate=true;
System.out.println("entered DataIntegrityViolationException blok");
System.out.println("exception occured");
//seqobj=seqrepo.findByData(sequence);
seqobj=seqrepo.getSequenceRestData(sequence);
seqid=seqobj.getSequencesId();
seqnamerepo.insertsequencename(genename, version, seqid);
System.out.println("After printing cause");
log.error("Exception for the sequence " + sequence);
}
if(!isDuplicate){
seqobj=seqrepo.findByData(sequence);
seqid=seqobj.getSequencesId();
seqnamerepo.insertsequencename(genename, version, seqid);
}
}
catch(DataIntegrityViolationException ex){
System.out.println("entered DataIntegrityViolationException blok");
System.out.println("exception occured");
seqobj=seqrepo.getSequenceRestData(sequence);
seqid=seqobj.getSequencesId();
seqnamerepo.insertsequencename(genename, version, seqid);
System.out.println("After printing cause");
log.error("Exception for the sequence " + sequence);
}
catch(ConstraintViolationException ex){
System.out.println("entered ConstraintViolationException blok");
System.out.println("exception occured");
seqobj=seqrepo.findByData(sequence);
seqobj=seqrepo.findByData(sequence);
seqid=seqobj.getSequencesId();
seqnamerepo.insertsequencename(genename, version, seqid);
System.out.println("After printing cause");
log.error("Exception for the sequence " + sequence);
//log.error("Excpetion occured whle inserting into DB", ex);
// throw ex;
}
catch (Exception ex){
System.out.println("After printing cause");
log.error("Exception for the sequence " + sequence);
// log.error("Excpetion occured whle inserting into DB", ex);
}
}
}
这是我的存储库类
package edu.unomaha.ist.bioinformatics.repository;
@Repository public interface SequenceNamesRepo extends JpaRepository<SequencesNamesRest,Serializable>{
@Modifying
@Query(nativeQuery=true, value=ApplicationQueries.INSERTSEQUENCENAMEREST)
public void insertsequencename(String name,int version,int id);
}
我的逻辑是，我在表中有一个可能抛出DataIntigrityException的唯一列。因此，当它与方法seqrepo.insertsequence一起发生时，我尝试在另一个表中获取序列和数据插入。但是插入另一张表并没有发生。当没有异常时，一切正常，数据被插入两个表中（请检查if（！isDuplicate）下的代码）。只有当我得到异常时，才会在第二个表中提交数据。
我收到以下异常
