Question

我正在尝试将我的Spring MVC项目移至3.2.4。

当我尝试在IntelliJ中运行应用程序时，如前所述使用Maven，我收到的错误是无法从Spring中找到一系列注释类...

@Bean
@Configuration
@ComponentScan
@PropertySource

都无法解决类错误消息而失败。

其他注释没问题，这让我觉得这是一个依赖问题，因为Spring版本是我项目代码库的主要变化。

Spring 3.2.4是否更改了包装中的注释？

我当前的pom（为简洁起见删除了一些位）：

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"

Answer 1

POM中存在org.springframework:spring-context的重复依赖项，可能导致类路径冲突。第一个是使用版本3.2.4.RELEASE的编译依赖项，第二个是使用版本3.0.0.RELEASE的运行时依赖项。

我建议你删除第二个，因为它是不必要的，应该被第一个取代。

Answer 2

对于出了什么问题，Spring并不啰嗦。要对此进行调试，请将带注释的类复制到.war项目中并使其在那里工作。很多事情可能是错误的，但春天只会说不满意的自动接线。它应该是开箱即用的，所以有些事情没有做好。未设置的属性，未满足的依赖性等。当你在项目中复制它时，你可以简化问题，一旦它在那里工作，移回课程它应该工作正常！

为什么Maven构建不能解析Spring @Bean @Configuration等注释？
