是不是哪里有写重复了。

没啊  我刚学的Springmvc  好多都不是很懂 要不你远程帮我看看？

你是不是没有在配置文件中定义JdbcTemplate呀

定义啦 <?xml version="1.0" encoding="UTF-8"?>

你才用注解自动装配吗？我看你配置文件没有配置<context:component-scan />  呀

在另一个xml文件中啊

自动注入的时候，找不到对应的bean
原因是：对应要注入的实现类没有 加注解，如dao层 @Repository  如service层  @Service 如controller层 @Controller

谢啦！  但是我dao层 @Repository  如service层  @Service 如controller层 @Controller都写注解了

很明显，你在Spring mvc的配置时候，activityDaoImpl这个Bean除了问题~

是不是你在activityDaoImpl类中的属性没有jdbcTemplate，或者是名字不对？

NoSuchBeanDefinitionException: No matching bean of type [org.springframework.jdbc.core.JdbcTemplate] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency

这个问题你有解决么
