springMVC属性未注入
--------------------编程问答-------------------- 错误提示：Invalid property 'tAddHandle' of bean class [controller.T_UserAddController]: No property 'tAddHandle' found，我已经在controller.T_UserAddController中写了tAddHandle的setter方法了，难道没用注入？ --------------------编程问答-------------------- 上面错误提示错了，应该是：Invalid property 'taddHandle' of bean class [controller.T_UserAddController]: No property 'taddHandle' found，我已经在controller.T_UserAddController中写了taddHandle的setter方法了，难道没用注入？ --------------------编程问答-------------------- 如果你确定你的setter方法没问题，是肯定会注入的。

No property 'taddHandle' found， 报了，最好仔细检查自己的代码。
spring-mvc ,用注解更方便好用 --------------------编程问答--------------------
现在我什么都没改，myeclipse又不报错了，刚才我在html中加几个字，但运行时候myeclipse却无动于衷，仍然运行着我改过之前的代码，myeclipse是不是需要一定时间来反映程序改动？我都无语了 --------------------编程问答-------------------- 项目重新加载一下呗，
--------------------编程问答-------------------- 配置的：<ref bean="taddHandle"/> 报错的 tAddHandle ，2个bean的名称不同啊
，重新部署项目 --------------------编程问答-------------------- 你是想了解一下springmvc ?
要不你试试3.0的很好用，自带文档很好
