本文详细介绍了如何在Spring中配置异步任务，包括在配置文件中添加必要的XML命名空间和属性，设置异步执行器参数，以及使用注解扫描来发现带有@Service注解的组件。此外，还提到了在SpringBoot中启用异步任务的方法。

1、如果是配置文件的，需要在文件里加如下配置

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xmlns:tx="http://www.springframework.org/schema/tx"
      xmlns:context="http://www.springframework.org/schema/context"
      xmlns:task="http://www.springframework.org/schema/task"
      xmlns:aop="http://www.springframework.org/schema/aop" xmlns:jpa="http://www.springframework.org/schema/data/jpa"
      xsi:schemaLocation="http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.1.xsd
        http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd
        http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.1.xsd
        http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task-3.0.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd
      http://www.springframework.org/schema/data/repository http://www.springframework.org/schema/data/repository/spring-repository-2.1.xsd
        http://www.springframework.org/schema/data/jpa http://www.springframework.org/schema/data/jpa/spring-jpa.xsd"
      default-lazy-init="true">
<task:annotation-driven executor="asyncExecutor" />
<task:executor id="asyncExecutor" pool-size="100-10000" queue-capacity="10"/>
<!-- 注解扫描 -->
<context:component-scan base-package="com.shby.product">
   <context:include-filter type="annotation"
                     expression="org.springframework.stereotype.Service" />
</context:component-scan>

方法名加@@Async

如果是SpringBoot加@Enableasync
