@runwith(springjunit4classrunner.class) @contextconfiguration(locations = { "file:spring-configuration/unit-test-config.xml" }) public abstract class abstracttestcaseunit { @resource(name = "parser") private dataparser parser;; @resource(name = "writer") private datawriter writer; public dataparser getmessageparser() { homecoming parser; } public datawriter getdatawriter() { homecoming writer; } }

dataparsetest.java

public class dataparsertest extends abstracttestcaseunit { @test public void testparsemessagehappycase() {...} }

it seems mixing different (incompatible) versions of spring components. check classpath.

if using project management tool maven or gradle, ensure dependencies of project not contain spring artifacts, otherwise picked transitive dependency mechanism.

if using ide eclipse , maven, can open pom.xml pom editor , check in dependency hierarchy tab resolved dependencies. can exclude offending (often older) dependency.
