- org.springframework.batch.repeat.context.SynchronizedAttributeAccessor
- - org.springframework.batch.core.scope.context.JobContext

所有已实现的接口:
org.springframework.core.AttributeAccessor
```
public class JobContext
extends SynchronizedAttributeAccessor
```
A context object that can be used to interrogate the current JobExecution and some of its associated properties using expressions based on bean paths. Has public getters for the job execution and convenience methods for accessing commonly used properties like the ExecutionContext associated with the job execution.

方法概要

所有方法实例方法具体方法
修饰符和类型	方法	说明
`void`	`close()`	Clean up the context at the end of a step execution.
`boolean`	`equals(java.lang.Object other)`	Extend the base class method to include the job execution itself as a key (i.e. two contexts are only equal if their job executions are the same).
`java.lang.String`	`getId()`
`JobExecution`	`getJobExecution()`	The current `JobExecution` that is active in this context.
`java.util.Map<java.lang.String,java.lang.Object>`	`getJobExecutionContext()`
`java.lang.String`	`getJobName()`	Convenient accessor for current job name identifier.
`java.util.Map<java.lang.String,java.lang.Object>`	`getJobParameters()`
`java.util.Properties`	`getSystemProperties()`	Convenient accessor for System properties to make it easy to access them from placeholder expressions.
`int`	`hashCode()`	Overrides the default behaviour to provide a hash code based only on the job execution.
`void`	`registerDestructionCallback(java.lang.String name, java.lang.Runnable callback)`	Allow clients to register callbacks for clean up on close.
`java.lang.Object`	`removeAttribute(java.lang.String name)`	Override base class behaviour to ensure destruction callbacks are unregistered as well as the default behaviour.
`java.lang.String`	`toString()`

  - getJobName
```
public java.lang.String getJobName()
```
    Convenient accessor for current job name identifier.
    返回:
    the job name identifier of the enclosing JobInstance associated with the current JobExecution
  - getSystemProperties
```
public java.util.Properties getSystemProperties()
```
    Convenient accessor for System properties to make it easy to access them from placeholder expressions.
    返回:
    the current System properties
  - getJobExecutionContext
```
public java.util.Map<java.lang.String,java.lang.Object> getJobExecutionContext()
```
    返回:
    a map containing the items from the job ExecutionContext
  - getJobParameters
```
public java.util.Map<java.lang.String,java.lang.Object> getJobParameters()
```
    返回:
    a map containing the items from the JobParameters
  - registerDestructionCallback
```
public void registerDestructionCallback(java.lang.String name,
                                        java.lang.Runnable callback)
```
    Allow clients to register callbacks for clean up on close.
    参数:
    name - the callback id (unique attribute key in this context)
    callback - a callback to execute on close
  - removeAttribute
```
@Nullable
public java.lang.Object removeAttribute(java.lang.String name)
```
    Override base class behaviour to ensure destruction callbacks are unregistered as well as the default behaviour.
    指定者:
    removeAttribute 在接口中 org.springframework.core.AttributeAccessor
    覆盖:
    removeAttribute 在类中 SynchronizedAttributeAccessor
    另请参阅:
    SynchronizedAttributeAccessor.removeAttribute(String)
  - close
```
public void close()
```
    Clean up the context at the end of a step execution. Must be called once at the end of a step execution to honour the destruction callback contract from the StepScope.
  - getJobExecution
```
public JobExecution getJobExecution()
```
    The current JobExecution that is active in this context.
    返回:
    the current JobExecution
  - getId
```
public java.lang.String getId()
```
    返回:
    unique identifier for this context based on the step execution
  - equals
```
public boolean equals(java.lang.Object other)
```
    Extend the base class method to include the job execution itself as a key (i.e. two contexts are only equal if their job executions are the same).
    覆盖:
    equals 在类中 SynchronizedAttributeAccessor
  - hashCode
```
public int hashCode()
```
    Overrides the default behaviour to provide a hash code based only on the job execution.
    覆盖:
    hashCode 在类中 SynchronizedAttributeAccessor
  - toString
```
public java.lang.String toString()
```
    覆盖:
    toString 在类中 SynchronizedAttributeAccessor
