所有已实现的接口:
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.

修饰符和类型	方法	说明
`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.

  - 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.
    参数:
    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.
    参数:
    jobExecutionIncrementer - the DataFieldMaxValueIncrementer
  - afterPropertiesSet
```
public void afterPropertiesSet()
                        throws java.lang.Exception
```
    指定者:
    afterPropertiesSet 在接口中 org.springframework.beans.factory.InitializingBean
    覆盖:
    afterPropertiesSet 在类中 AbstractJdbcBatchMetadataDao
    抛出:
    java.lang.Exception
  - findJobExecutions
```
public java.util.List<JobExecution> findJobExecutions(JobInstance job)
```
    从接口复制的说明: JobExecutionDao
    Return all JobExecutions for given JobInstance, sorted backwards by creation order (so the first element is the most recent).
    指定者:
    findJobExecutions 在接口中 JobExecutionDao
    参数:
    job - parent JobInstance of the JobExecutions to find.
    返回:
    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.
    指定者:
    saveJobExecution 在接口中 JobExecutionDao
    参数:
    jobExecution - JobExecution instance to be saved.
    抛出:
    java.lang.IllegalArgumentException - if jobExecution is null, as well as any of it's fields to be persisted.
    另请参阅:
    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.
    指定者:
    updateJobExecution 在接口中 JobExecutionDao
    参数:
    jobExecution - JobExecution instance to be updated.
    另请参阅:
    JobExecutionDao.updateJobExecution(JobExecution)
  - getLastJobExecution
```
public JobExecution getLastJobExecution(JobInstance jobInstance)
```
    从接口复制的说明: JobExecutionDao
    Find the last JobExecution to have been created for a given JobInstance.
    指定者:
    getLastJobExecution 在接口中 JobExecutionDao
    参数:
    jobInstance - the JobInstance
    返回:
    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)
```
    指定者:
    getJobExecution 在接口中 JobExecutionDao
    参数:
    executionId - Long containing the id of the execution.
    返回:
    the JobExecution for given identifier.
  - findRunningJobExecutions
```
public java.util.Set<JobExecution> findRunningJobExecutions(java.lang.String jobName)
```
    指定者:
    findRunningJobExecutions 在接口中 JobExecutionDao
    参数:
    jobName - String containing the name of the job.
    返回:
    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)
```
    从接口复制的说明: 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.
    指定者:
    synchronizeStatus 在接口中 JobExecutionDao
    参数:
    jobExecution - to be updated.
  - getJobParameters
```
protected JobParameters getJobParameters(java.lang.Long executionId)
```
    参数:
    executionId - Long containing the id for the execution.
    返回:
    job parameters for the requested execution id
