想要自定义一个job,必须要继承一个抽象类AbstractJob,然后在
`safeExecute()`
方法中执行业务代码,示例代码如下:
```
java
public
class
demoJob
extends
AbstractJob
{
@Autowired
private
xxxService
service
;
//业务类
@Override
public
void
safeExecute
(
JobExecutionContext
jobExecutionContext
)
throws
Exception
{
//map中可以获取上方定义的参数,key为参数名称,value为参数值
JobDataMap
map
=
jobExecutionContext
.
getMergedJobDataMap
();
try
{
service
.
dosomething
();
}
catch
(
Exception
e
)
{
if
(
logger
.
isErrorEnabled
())
{
logger
.
error
(
e
.
getMessage
(),
e
);
}
exception
=
e
;
throw
e
;
}
if
(
exception
!=
null
)
{
setExecutionSummary
(
exception
.
getClass
().
getName
()
+
":"
+
exception
.
getMessage
());
}
else
{
setExecutionSummary
(
"执行完成!"
);
}
}
@Override
public
boolean
isRefireImmediatelyWhenException
()
{
//任务发生异常时候进行的动作
//false 挂起当前JOB等待处理
//true 继续执行
return
false
;
}
}
```
注意:
调用
`setExecutionSummary()`
方法可以在执行记录中,记录你的业务数据的记录,或者抛出的异常的具体信息。
在上下文中获取JobDataMap可以拿到你在任务配置中定义的参数
