Do a block into the database operation:

Shielding against erroneous data entry

<base-package= "Com.liuyang"/>    <!--context: Exclude-filter type= "Annotation" expression= "Org.springframework.stereotype.Controller"         -

This is actually written off, it is also very handy. Plus, it appears that the top of the article does not find the URL address injection error.

You can configure the mask here so that the database does not enter the error data.

<Context:component-scanBase-package= "Com.liuyang">        <Context:include-filtertype= "Annotation"expression= "Org.springframework.stereotype.Controller" />        <Context:exclude-filtertype= "Annotation"expression= "Org.springframework.stereotype.Service" />    </Context:component-scan>

@Overridepublic int insertdept (Dept Dept) throws Exception {int i = 0;i = Deptdao.insertdept (Dept); Integer.parseint ("AA") ; return i;}

Hope to help you, thank you for watching.
