[FIXED] mule-module-spring-config and spring bean version mismatch

Issue

I am getting error :

Caused by: org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException: Line 5 in XML document from URL [jar:file:/<File path>/.m2/repository/org/mule/modules/mule-module-spring-config/3.9.2/mule-module-spring-config-
3.9.2.jar!/registry-bootstrap-mule-config.xml] is invalid; nested exception is org.xml.sax.SAXParseException; lineNumber: 5; columnNumber: 122; cvc-elt.1.a: Cannot find the declaration of element 'beans'.
        at <TestclassPath>.<init>(<ClassName>.java:32)

while using mule-module-spring-config-3.9.2.jar and spring bean version 5.3.22.

but same code passes when we use Spring-bean version as 4.3.18.RELEASE.

SpringBeanTest.xml:

<?xml version="1.0" encoding="UTF-8"?>

Solution

Mule 3.x doesn't allow to use a different Spring Framework version than the one that is included in its distribution. Mule 3.9.2 includes for example includes Spring 4.1.9. Using a different version of Spring than the one included in the Mule version can cause unexpected errors -as you are experiencing- and is not supported. Mule 3.9.5, the final Mule 3.x release, supports Spring 4.3.29.

In particular Spring 5 is not supported by any version of Mule 3.x. See https://help.mulesoft.com/s/article/Spring-versions-throughout-each-version-of-Mule for more information of the Spring versions supported until Mule 3.9.2.

Mule 4 isolates the version of Spring used by the runtime from the one that is used by applications through the Spring Module, however it is not compatible with Mule 3 applications.
