在applicationContext.xml </mvc：annotation-driven>中添加<mvc：annotation-driven>时出错

标签： java xml spring hibernate spring-mvc

根据Spring MVC文档，标记执行以下操作：

  
      
  1. 配置Spring 3类型ConversionService（替代PropertyEditors）
    2.   
  2. 添加了对使用@NumberFormat
    3. 格式化数字字段的支持   
  3. 如果Joda Time在类路径上，则添加对使用@DateTimeFormat格式化Date，Calendar和Joda Time字段的支持
    4.   
  4. 如果JSR-303提供程序在类路径上，则添加对使用@Valid验证@Controller输入的支持
    5.   
  5. 如果JAXB在类路径上（使用@RequestBody / @ ResponseBody进行HTTP消息转换），则支持读取和写入XML支持
    6.   
  6. 如果杰克逊在类路径上（与＃5一样），则添加对JSON读写的支持。
    7.   

但是当我将它添加到我的applicationContext.xml文件时，在启动服务器（JBoss EAP 6.1）时会引发错误。

这是错误：

删除标记<mvc:annotation-driven>一切正常。可能有什么不对？任何帮助将不胜感激。

谢谢！

答案 0 :(得分：3)

在web.xml文件中，您指定将使用Java配置来设置MVC组件，但是尝试在applicationContext.xml文件中设置MVC组件。

ContextLoaderListener中的web.xml设置为启动/WEB-INF/applicationContext.xml配置文件。 applicationContext.xml的容器设置不应包含MVC组件，但应该用于在MVC范围之外注册bean，例如用于数据持久性的bean。

如果您真的想使用Java Configuration来设置Spring MVC组件，则必须将applicationContext.xml文件中建立的所有Spring MVC组件移动到使用@Configuration注释的Java类并转换XML bean在Java中的适当配置。

请参阅：Spring + Web MVC: dispatcher-servlet.xml vs. applicationContext.xml (plus shared security)
