SpringMVC File Upload

這次主要是公司內部使用的項目，需要做到可以上傳，並且統計count的數字。

使用的是springmvc

先來看maven

然後是SpringMVC配置文件

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:aop="http://www.springframework.org/schema/aop" xmlns:context="http://www.springframework.org/schema/context"

</beans>

最後是Controller和畫面

	}

	}

			userService.deleteUser(Integer.valueOf(ids[i]));
		}

		return "users/search";
	}

}

package cn.edu.ken.commons.util;
