The prefix "xxxx" for Element "xxxxxx" in spring appears to be not bound. That is, some tags are not prompted and you cannot find a DTD constraint file

When learning the spring framework, are you experiencing this situation:


Watch someone else's video knock code, but the content of their own editor is not the same as the video; you want to add some tag hints in eclipse, but you can't find the DTD constraint file when you manually add a DTD constraint file, you can do this:


<beans xmlns= "Http://www.springframework.org/schema/beans"
Xmlns:xsi= "Http://www.w3.org/2001/XMLSchema-instance"
Xmlns:util= "Http://www.springframework.org/schema/util"
xmlns:p= "http://www.springframework.org/schema/p"
xsi:schemalocation= "Http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/ Spring-beans.xsd
Http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.0.xsd ">


By comparing the beginning of your XML file with a selective addition, you can solve the problem by adding duplicates of the content.


Mine is not prompt util tag, finally put that xmlns:util= "Http://www.springframework.org/schema/util" and http://www.springframework.org/ Schema/util Http://www.springframework.org/schema/util/spring-util-4.0.xsd is added to a specific location, the corresponding label hints will come out and eclipse will not throw an exception.


But what I wrote about these content is just one of the things that will be updated during the follow-up discovery process, if there's a DTD who has more tag hints hopefully can upload the download
