Question

我在尝试创建新的Spring MVC webapp时遇到以下错误

ClassNotFoundException: org.springframework.config.java.JavaConfigWebApplicationContext

奇怪的是，JavaConfigWebApplicationContext具有以下依赖性

<dependency>
  <groupId>org.springframework.javaconfig</groupId>
  <artifactId>spring-javaconfig</artifactId>
  <version>1.0.0.m3</version>
</dependency>

这似乎是关闭的，因为我不记得在其他Spring项目中明确添加上述依赖项。我必须错误地配置应用程序。这是我的配置

Answer 1

spring-javaconfig是一个相当古老的实验性实施。使用Spring 3.1或更高版本，Spring配置包含在Spring Core Framework中。

请参阅AnnotationConfigWebApplicationContext。

Answer 2

使用以下代码段。上面的答案是正确的，尽管这正是你所需要的：

    <init-param>
        <param-name>contextClass</param-name>
        <param-value>org.springframework.web.context.support.AnnotationConfigWebApplicationContext</param-value>
    </init-param>

使用Spring JavaConfigWebApplicationContext的ClassNotFoundException
