Question

我们有一个在春季3.0编写的应用程序。我注意到@Async不起作用。我四处搜索，发现我需要添加

<task:annotation-driven executor="myExecutor" scheduler="myScheduler"/>
<task:executor id="myExecutor" pool-size="5"/>
<task:scheduler id="myScheduler" pool-size="10"/>

但是当我这样做时，我得到了一个例外。

这是我的配置文件：

有什么建议吗？

Answer 1

要@Async工作（我假设基于注释的配置），您需要做两件事：

<task:annotation-driven/>
使用@Async

......那就是它。

您的例外情况并不表示@Async无法正常工作。它表示字段HomepageSrvImpl存在自动装配问题。

Answer 2

这是一个古老的问题，但由于它到目前为止没有并且已经接受了答案，所以我们走了。

问题的实质是@Async机制的工作原理。正在发生的事情的提示是stacktrace的这一部分，特别是用粗体标记的部分：

引起：java.lang.IllegalArgumentException：无法设置 package.srv.homepage.impl.HomepageSrvImpl字段 package.mvc.controller.browser.LocationBrowserController.homepageSrvImpl 到$ Proxy24

正在发生的是，为了能够拦截用@Async标记的方法的调用，Spring需要为它创建一个代理。

正如用户＆＃34; El Guapo＆＃34;在另一个答案中，您可能声明了自动装配属性的类型，而不是使用接口，而是使用实际的实现。（请注意，stackTrace中的错误并不是专门指向被代理的对象，而是指向需要将其作为属性自动装配的对象，但它仍指向正确方向的故障排除。）

这可以正常工作，直到您开始使用@Async注释，因为这会强制sprint创建代理并且无法自动装配它。

我还没有对它进行过测试，但是我假设Spring会需要将代码交织在一起（例如@Transactional）。

Answer 3

我有同样的问题......我有一堆差异“IMPLS”实现了我试图自动装配的接口，问题是我是自动装配实现而不是接口......只要我开始自动装配接口（使用@Qaulifier）一切正常A-OK !!!!

Answer 4

堆栈跟踪中的此部分指示错误是什么。字段homepageSrvImpl应该是接口类型而不是具体类。如果你无法弄清楚添加的定义 LocationBrowserController和HomepageSrvImpl - 只是班级＆amp;自动装配的部分。

Caused by: java.lang.IllegalArgumentException: Can not set
package.srv.homepage.impl.HomepageSrvImpl field
package.mvc.controller.browser.LocationBrowserController.homepageSrvImpl to $Proxy24

Answer 5

我也遇到了同样的问题。

将属性proxy-target-class="true"添加到<task:annotation-driven/>为我修复了它。我的定义现在看起来像这样：

<task:annotation-driven 
   executor="myExecuter" scheduler="myScheduler" proxy-target-class="true"/>
