```
public JdbcExecutionContextDao()
```
- 方法详细资料
  - setSerializer
```
public void setSerializer(ExecutionContextSerializer serializer)
```
    Setter for Serializer implementation
    参数:
    serializer - ExecutionContextSerializer instance to use.
  - setShortContextLength
```
public void setShortContextLength(int shortContextLength)
```
    The maximum size that an execution context can have and still be stored completely in short form in the column SHORT_CONTEXT. Anything longer than this will overflow into large-object storage, and the first part only will be retained in the short form for readability. Default value is 2500. Clients using multi-bytes charsets on the database server may need to reduce this value to as little as half the value of the column size.
    参数:
    shortContextLength - int max length of the short context.
  - getExecutionContext
```
public ExecutionContext getExecutionContext(JobExecution jobExecution)
```
    指定者:
    getExecutionContext 在接口中 ExecutionContextDao
    参数:
    jobExecution - JobExecution instance that contains the context.
    返回:
    execution context associated with the given jobExecution
  - getExecutionContext
```
public ExecutionContext getExecutionContext(StepExecution stepExecution)
```
    指定者:
    getExecutionContext 在接口中 ExecutionContextDao
    参数:
    stepExecution - StepExecution instance that contains the context.
    返回:
    execution context associated with the given stepExecution
  - updateExecutionContext
```
public void updateExecutionContext(JobExecution jobExecution)
```
    从接口复制的说明: ExecutionContextDao
    Persist the updates of execution context associated with the given jobExecution. Persistent entry should already exist for this context.
    指定者:
    updateExecutionContext 在接口中 ExecutionContextDao
    参数:
    jobExecution - JobExecution instance that contains the context.
  - updateExecutionContext
```
public void updateExecutionContext(StepExecution stepExecution)
```
    从接口复制的说明: ExecutionContextDao
    Persist the updates of execution context associated with the given stepExecution. Persistent entry should already exist for this context.
    指定者:
    updateExecutionContext 在接口中 ExecutionContextDao
    参数:
    stepExecution - StepExecution instance that contains the context.
  - saveExecutionContext
```
public void saveExecutionContext(JobExecution jobExecution)
```
    从接口复制的说明: ExecutionContextDao
    Persist the execution context associated with the given jobExecution, persistent entry for the context should not exist yet.
    指定者:
    saveExecutionContext 在接口中 ExecutionContextDao
    参数:
    jobExecution - JobExecution instance that contains the context.
  - saveExecutionContext
```
public void saveExecutionContext(StepExecution stepExecution)
```
    从接口复制的说明: ExecutionContextDao
    Persist the execution context associated with the given stepExecution, persistent entry for the context should not exist yet.
    指定者:
    saveExecutionContext 在接口中 ExecutionContextDao
    参数:
    stepExecution - StepExecution instance that contains the context.
  - saveExecutionContexts
```
public void saveExecutionContexts(java.util.Collection<StepExecution> stepExecutions)
```
    从接口复制的说明: ExecutionContextDao
    Persist the execution context associated with each stepExecution in a given collection, persistent entry for the context should not exist yet.
    指定者:
    saveExecutionContexts 在接口中 ExecutionContextDao
    参数:
    stepExecutions - a collection of StepExecutions that contain the contexts.
  - setLobHandler
```
public void setLobHandler(org.springframework.jdbc.support.lob.LobHandler lobHandler)
```
  - 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
