JobExecutionDao, org.springframework.beans.factory.InitializingBean
```
public class JdbcJobExecutionDao
extends AbstractJdbcBatchMetadataDao
implements JobExecutionDao, org.springframework.beans.factory.InitializingBean
```
JDBC implementation of JobExecutionDao. Uses sequences (via Spring's DataFieldMaxValueIncrementer abstraction) to create all primary keys before inserting a new row. Objects are checked to ensure all mandatory fields to be stored are not null. If any are found to be null, an IllegalArgumentException will be thrown. This could be left to JdbcTemplate, however, the exception will be fairly vague, and fails to highlight which field caused the exception.

Method Summary

All Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`void`	`afterPropertiesSet()`
`java.util.List<JobExecution>`	`findJobExecutions(JobInstance job)`	Return all `JobExecution`s for given `JobInstance`, sorted backwards by creation order (so the first element is the most recent).
`java.util.Set<JobExecution>`	`findRunningJobExecutions(java.lang.String jobName)`
`JobExecution`	`getJobExecution(java.lang.Long executionId)`
`protected JobParameters`	`getJobParameters(java.lang.Long executionId)`
`JobExecution`	`getLastJobExecution(JobInstance jobInstance)`	Find the last `JobExecution` to have been created for a given `JobInstance`.
`void`	`saveJobExecution(JobExecution jobExecution)`	SQL implementation using Sequences via the Spring incrementer abstraction.
`void`	`setExitMessageLength(int exitMessageLength)`	Public setter for the exit message length in database.
`void`	`setJobExecutionIncrementer(org.springframework.jdbc.support.incrementer.DataFieldMaxValueIncrementer jobExecutionIncrementer)`	Setter for `DataFieldMaxValueIncrementer` to be used when generating primary keys for `JobExecution` instances.
`void`	`synchronizeStatus(JobExecution jobExecution)`	Because it may be possible that the status of a JobExecution is updated while running, the following method will synchronize only the status and version fields.
`void`	`updateJobExecution(JobExecution jobExecution)`	Update given JobExecution using a SQL UPDATE statement.

public JdbcJobExecutionDao()
```
- Method Detail
  - setExitMessageLength
```
public void setExitMessageLength(int exitMessageLength)
```
    Public setter for the exit message length in database. Do not set this if you haven't modified the schema.
    Parameters:
    exitMessageLength - the exitMessageLength to set
  - setJobExecutionIncrementer
```
public void setJobExecutionIncrementer(org.springframework.jdbc.support.incrementer.DataFieldMaxValueIncrementer jobExecutionIncrementer)
```
    Setter for DataFieldMaxValueIncrementer to be used when generating primary keys for JobExecution instances.
    Parameters:
    jobExecutionIncrementer - the DataFieldMaxValueIncrementer
  - afterPropertiesSet
```
public void afterPropertiesSet()
                        throws java.lang.Exception
```
    Specified by:
    afterPropertiesSet in interface org.springframework.beans.factory.InitializingBean
    Overrides:
    afterPropertiesSet in class AbstractJdbcBatchMetadataDao
    Throws:
    java.lang.Exception
  - findJobExecutions
```
public java.util.List<JobExecution> findJobExecutions(JobInstance job)
```
    Description copied from interface: JobExecutionDao
    Return all JobExecutions for given JobInstance, sorted backwards by creation order (so the first element is the most recent).
    Specified by:
    findJobExecutions in interface JobExecutionDao
    Parameters:
    job - parent JobInstance of the JobExecutions to find.
    Returns:
    List containing JobExecutions for the jobInstance.
  - saveJobExecution
```
public void saveJobExecution(JobExecution jobExecution)
```
    SQL implementation using Sequences via the Spring incrementer abstraction. Once a new id has been obtained, the JobExecution is saved via a SQL INSERT statement.
    Specified by:
    saveJobExecution in interface JobExecutionDao
    Parameters:
    jobExecution - JobExecution instance to be saved.
    Throws:
    java.lang.IllegalArgumentException - if jobExecution is null, as well as any of it's fields to be persisted.
    See Also:
    JobExecutionDao.saveJobExecution(JobExecution)
  - updateJobExecution
```
public void updateJobExecution(JobExecution jobExecution)
```
    Update given JobExecution using a SQL UPDATE statement. The JobExecution is first checked to ensure all fields are not null, and that it has an ID. The database is then queried to ensure that the ID exists, which ensures that it is valid.
    Specified by:
    updateJobExecution in interface JobExecutionDao
    Parameters:
    jobExecution - JobExecution instance to be updated.
    See Also:
    JobExecutionDao.updateJobExecution(JobExecution)
  - getLastJobExecution
```
public JobExecution getLastJobExecution(JobInstance jobInstance)
```
    Description copied from interface: JobExecutionDao
    Find the last JobExecution to have been created for a given JobInstance.
    Specified by:
    getLastJobExecution in interface JobExecutionDao
    Parameters:
    jobInstance - the JobInstance
    Returns:
    the last JobExecution to execute for this instance or null if no job execution is found for the given job instance.
  - getJobExecution
```
@Nullable
public JobExecution getJobExecution(java.lang.Long executionId)
```
    Specified by:
    getJobExecution in interface JobExecutionDao
    Parameters:
    executionId - Long containing the id of the execution.
    Returns:
    the JobExecution for given identifier.
  - findRunningJobExecutions
```
public java.util.Set<JobExecution> findRunningJobExecutions(java.lang.String jobName)
```
    Specified by:
    findRunningJobExecutions in interface JobExecutionDao
    Parameters:
    jobName - String containing the name of the job.
    Returns:
    all JobExecution that are still running (or indeterminate state), i.e. having null end date, for the specified job name.
  - synchronizeStatus
```
public void synchronizeStatus(JobExecution jobExecution)
```
    Description copied from interface: JobExecutionDao
    Because it may be possible that the status of a JobExecution is updated while running, the following method will synchronize only the status and version fields.
    Specified by:
    synchronizeStatus in interface JobExecutionDao
    Parameters:
    jobExecution - to be updated.
  - getJobParameters
```
protected JobParameters getJobParameters(java.lang.Long executionId)
```
    Parameters:
    executionId - Long containing the id for the execution.
    Returns:
    job parameters for the requested execution id
