12 个解决方案

#1

No bean named 'fileUploadDao' is defined
fileUploadDao这个BEAN名字对吗。。

#2

纳闷。。。。应该对了。。。我有宣告啊！

#3

你spring配置文件有配置fileUploadDao这个bean么？或是配置错误，写错？

#4

有配置啊！<!--主键Bean类 -->
<property name="annotatedClasses">
<list>
<value>com.studysystem.model.user.UserInfor</value>
<value>com.studysystem.model.action.Action</value>
<value>com.studysystem.model.menu.Menu</value>
<value>com.studysystem.model.module.Module</value>
<value>com.studysystem.model.role.Role</value>
<value>com.studysystem.model.article.ArticleInfor</value>
<value>com.studysystem.model.article.ArticleStyle</value>
<value>com.studysystem.model.article.ArticleType</value>
<value>com.studysystem.model.article.Brand</value>
    <value>com.studysystem.model.uploadfile.FileUpload</value>
</list>
</property>

#5

No bean named 'fileUploadDao' is defined

注意大小写，最好复制。。。

#6

第一、有没有包冲突，一般将系统的删去，用spring security不会有问题。

第二、确保在spring的xml里面有<http>声明默认初始化。

第三、确保能够找到spring 的xml文件。

第四、注意大小写区分。

#7

<value>com.studysystem.model.action.Action</value>
<value>com.studysystem.mode……

你这个不是配置fileUploadDao的吧？

对于你所说jar冲突的可能性不大因为我之前实现用户模块的是正常的但是这个就莫名其妙。。。。包这种错误！

#9

这个问题解决了。。。既然用这个resource（bytype=xx.class）找到了！

#10

JUnit能够测试成功了以后！tomcat却报这个错！

相当的郁闷啊！

#11

名字大小写写错了吧

终于解决哥们！是这个问题。。。@repository（"xxx"）就可以搞定了
