我用3.1.1框架版本开发了Spring MVC应用，现在我想切换到4.0.1。

我正在使用 Maven 来处理所有依赖项。因此，当我更改 pom.xml 中的版本时，出现编译错误 JavaMailSenderImpl could not be resolved to type。

此外，我无法在 jars 中找到包 org.springframework.mail.javamail.JavaMailSenderImpl。但是从文档看来，这个包在最新版本中没有被删除。 我尝试再次清理项目和建筑，但没有帮助我。

那么知道我在这里做错了什么吗？

下面是 pom.xml 的部分 -

最佳答案

这是依赖，我错过了。所以我添加了以下依赖 -

        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-context-support</artifactId>
            <version>4.0.1.RELEASE</version>
        </dependency>

关于java - 切换到 4.0.1 版本后 "JavaMailSenderImpl cannot be resolved to a type"，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/21711462/
