java - Spring MVC 中的异常

转载作者：行者123 更新时间：2023-12-01 10:49:37

你好，我做了一点CRUD，没有WEB层，一切都可以工作。现在我附加了Spring MVC，但它不想工作。我正在尝试将应用程序部署到 Tomcat 中，并收到此异常。不明白为什么..请帮助。谢谢。

最佳答案

SynthesizingMethodParameter 仅在 Spring 4.2 中引入。如果您使用 Maven，则可以使用依赖项

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-core</artifactId>
    <version>4.2.3.RELEASE</version>
</dependency>
