首先创建一个自定义注解，此注解使用在流程抄送的service方法上
import java.lang.annotation.*;
/**
* 流程需要抄送的功能
*/
@Target(ElementType.METHOD)
@Retention(RetentionPolicy.RUNTIME)
public @interface FuncCCAnnotation {
String desc() default "";
String funcId() default "";
}
使用时只需要在方法上注解
/**
* 完成任务
*
* @param baseProcessForm 流程任务表单
* @return string
*/
@Override
@Transactional(rollbackFor = RuntimeException.class)
@FuncCCAnnotation(desc ="通过", funcId ="5")
public StringcompleteTask(BaseProcessForm baseProcessForm) {
//具体省略
}
