Add xmlns context with http as shown below  xmlns context  http   www springframework org schema context

This error can also be caused if the jar file that contains the XSD you require is not included in your deployed class path   Make sure the dependencies are available in your container

User · Answer

when you add context component-scan for the first time in an xml  the following needs to be added   xmlns context  http   www springframework org schema context   xsi schemaLocation  http   www springframework org schema beans http   www springframework org schema beans spring-beans xsd         http   www springframework org schema context http   www springframework org schema context spring-context xsd  gt

Add This Two Schema locations  That s enough and Efficient instead of adding all the unnecessary schema   http   www springframework org schema context  http   www springframework org schema context spring-context xsd

User · Answer

Change http to https of the marked error or all the URL ending with   xsd extension

User · Answer

The correct path shouldn t end with      I had it wrong that caused the trouble  Right way   http   www springframework org schema context http   www springframework org schema context spring-context xsd

It s too late but somewhat may useful to others     The matching wildcard is strict  but no declaration can be found for   element  context component-scan   which Means you have Missed some Declarations or The Required Declarations Not Found in Your XML  In my case i forgot to add the follwoing   http   www springframework org schema aop http   www springframework org schema aop spring-aop-4 0 xsd http   www springframework org schema tx http   www springframework org schema tx spring-tx-4 0 xsd   After Adding this the Problem Gone away   lt  xml version  1 0  encoding  UTF-8   gt   lt beans beans xmlns  http   www springframework org schema mvc      xmlns xsi  http   www w3 org 2001 XMLSchema-instance      xmlns beans  http   www springframework org schema beans      xmlns context  http   www springframework org schema context      xmlns tx  http   www springframework org schema tx      xsi schemaLocation  http   www springframework org schema mvc http   www springframework org schema mvc spring-mvc xsd         http   www springframework org schema beans http   www springframework org schema beans spring-beans xsd         http   www springframework org schema context http   www springframework org schema context spring-context xsd         http   www springframework org schema aop http   www springframework org schema aop spring-aop-4 0 xsd         http   www springframework org schema tx http   www springframework org schema tx spring-tx-4 0 xsd  gt

This path of the schema location is wrong   http   www springframework org schema beans   The correct path should end with     http   www springframework org schema beans

I was having issues with   Caused by  org xml sax SAXParseException  cvc-complex-type 2 4 c  The matching wildcard is strict  but no declaration can be found for element  security http    and for me I had to add the spring-security-config jar to the classpath  http   docs spring io spring-security site docs 3 1 x reference ns-config html  EDIT   It might be that you have the correct dependency in your pom   But     If you are using multiple spring dependencies and assembling into a single jar then the META-INF spring schemas is probably being overwritten by the spring schemas of another of your spring dependencies    Extract that file from your assembled jar and you ll understand   Spring schemas is just a bunch of lines that look like this   http    www springframework org schema p org springframework beans factory xml SimplePropertyNamespaceHandler http    www springframework org schema beans spring-beans-3 0 xsd org springframework beans factory xml spring-beans-3 0 xsd   But if another dependency overwrites that file  then the definition will be retrieved from http  and if you have a firewall proxy it will fail to get it   One solution is to append spring schemas and spring handlers into a single file   Check   Idea to avoid that spring handlers spring schemas get overwritten when merging multiple spring dependencies in a single jar

You have not specified the schema location of the context namespace  that is the reason for this specific error    lt beans         xmlns context  http   www springframework org schema context    xsi schemaLocation       http   www springframework org schema beans     http   www springframework org schema beans spring-beans-2 5 xsd     http   www springframework org schema aop     http   www springframework org schema aop spring-aop-2 5 xsd     http   www springframework org schema tx     http   www springframework org schema tx spring-tx-2 5 xsd     http   www springframework org schema context     http   www springframework org schema context spring-context xsd  gt

There are  META-INF spring schemas  files in various Spring jars containing the mappings for the URLs that are intercepted for local resolution  If a particular xsd URL is not listed in these files  for example after switching from http to https  Spring tries to load schemas from the Internet and if the system has no Internet connection it fails and causes this error   This can be the case with Spring Security v5 2 and up where there is no http mapping for the xsd file   To fix it change   xsi schemaLocation       http   www springframework org schema beans          http   www springframework org schema beans spring-beans xsd     http   www springframework org schema security       http   www springframework org schema security spring-security xsd    to  xsi schemaLocation       http   www springframework org schema beans          https   www springframework org schema beans spring-beans xsd     http   www springframework org schema security       https   www springframework org schema security spring-security xsd    Note that only actual xsd URL was modified from http to https  only two places above

If using STS  you can in Eclipse mark the configuration file as  Bean Configuration  file  you can specify that when creating or on right click on a XML file      You project has to have Spring Nature  right click on maven project for example      then spring xml is opened by default with Spring Config Editor    and this editor has Namespaces tab    Which enables you to specify the namespaces     Please be aware  that it depends on dependencies  using maven project   so if spring-tx is not defined in maven s pom xml  option is not there  which prevents you to have The matching wildcard is strict  but no declaration can be found for element   39 tx annotation-driven  39    39 context component-scan  39  problem

With namespace declaration and schema location you can also check the syntax of the namespace use for example  -   lt beans xmlns context  http   www springframework org schema context          xsi schemaLocation  http   www springframework org  enter code here schema context         http   www springframework org schema context spring-context xsd  gt    lt context annotation-driven  gt     lt  -- This is wrong -- gt   lt context annotation-config  gt   lt  -- This should work -- gt
