我正在按照一个例子去 spring mvc + hibernate，但是我遇到了很多问题，现在我有一些看起来像错误但我不知道的东西。 我正在使用 STS 和 spring MVC 项目模板。

在

<context:component-scan base-package="com.carloscortina.paidosTest" />
我在行号处得到这个红色标记:

Errors)

我不知道这是否会导致下一个错误:

我在定义方法的那一行也有一个标记

我不知道这些信息是否足够。 我希望有人能给我建议，在此先感谢。
最佳答案
在谷歌搜索并担心这个该死的小红箭头后，我开始知道它只是来自 IDE 的一个注释。
那些小标记是指代交易元素的信号线。或者与 @Transactional 元素相关。
关于spring-mvc - 通过 STS(eclipse) 建议(红色标记)它们是什么意思，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/18039104/
