My goal I want to achieve is to introduce enum in Spring managed bean.
I do not want my bean to be configured in XML (there is no reason for this other than this non-working enumeration).
I have a simple maven project:
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>net.betlista</groupId> <artifactId>test.spring.enum-injection</artifactId> <version>1.0-SNAPSHOT</version> <dependencies> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>3.1.3.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aspects</artifactId> <version>3.1.3.RELEASE</version> </dependency> <dependency> <groupId>aspectj</groupId> <artifactId>aspectjrt</artifactId> <version>1.5.4</version> </dependency> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>${junit.version}</version> <scope>test</scope> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> <version>3.1.3.RELEASE</version> <scope>test</scope> </dependency> </dependencies> <properties> <junit.version>4.11</junit.version> </properties> </project>
I created a simple test
import net.betlista.spring.enum_injection.EnumInjectionComponent; import org.junit.Assert; import org.junit.Test; import org.junit.runner.RunWith; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.test.context.ContextConfiguration; import org.springframework.test.context.junit4.SpringJUnit4ClassRunner; @RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration("classpath:applicationContext.xml") public class TestClass { @Autowired EnumInjectionComponent component; @Test public void test() { Assert.assertNotNull(component.roundingMode); } }
and my bean is
package net.betlista.spring.enum_injection; import java.math.RoundingMode; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Component; @Component public class EnumInjectionComponent { @Autowired public RoundingMode roundingMode; }
When I try to run my Ipm test, getting
java.lang.IllegalStateException: Failed to load ApplicationContext at org.springframework.test.context.TestContext.getApplicationContext(TestContext.java:157) at org.springframework.test.context.support.DependencyInjectionTestExecutionListener.injectDependencies(DependencyInjectionTestExecutionListener.java:109) at org.springframework.test.context.support.DependencyInjectionTestExecutionListener.prepareTestInstance(DependencyInjectionTestExecutionListener.java:75) at org.springframework.test.context.TestContextManager.prepareTestInstance(TestContextManager.java:321) at org.springframework.test.context.junit4.SpringJUnit4ClassRunner.createTest(SpringJUnit4ClassRunner.java:211) at org.springframework.test.context.junit4.SpringJUnit4ClassRunner$1.runReflectiveCall(SpringJUnit4ClassRunner.java:288) at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:12) at org.springframework.test.context.junit4.SpringJUnit4ClassRunner.methodBlock(SpringJUnit4ClassRunner.java:290) at org.springframework.test.context.junit4.SpringJUnit4ClassRunner.runChild(SpringJUnit4ClassRunner.java:231) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:50) at org.junit.runners.ParentRunner$3.run(ParentRunner.java:238) at org.junit.runners.ParentRunner$1.schedule(ParentRunner.java:63) at org.junit.runners.ParentRunner.runChildren(ParentRunner.java:236) at org.junit.runners.ParentRunner.access$000(ParentRunner.java:53) at org.junit.runners.ParentRunner$2.evaluate(ParentRunner.java:229) at org.springframework.test.context.junit4.statements.RunBeforeTestClassCallbacks.evaluate(RunBeforeTestClassCallbacks.java:61) at org.springframework.test.context.junit4.statements.RunAfterTestClassCallbacks.evaluate(RunAfterTestClassCallbacks.java:71) at org.junit.runners.ParentRunner.run(ParentRunner.java:309) at org.springframework.test.context.junit4.SpringJUnit4ClassRunner.run(SpringJUnit4ClassRunner.java:174) at org.eclipse.jdt.internal.junit4.runner.JUnit4TestReference.run(JUnit4TestReference.java:50) at org.eclipse.jdt.internal.junit.runner.TestExecution.run(TestExecution.java:38) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:467) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:683) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run(RemoteTestRunner.java:390) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:197) Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'enumInjectionComponent': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: public java.math.RoundingMode net.betlista.spring.enum_injection.EnumInjectionComponent.roundingMode; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No matching bean of type [java.math.RoundingMode] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

But in the log I see:
INFO: Destroying solitary org.s pringframework.beans.factory.support.DefaultListableBeanFactory@ 236527f: defining beans [Org.springframework.context.config.internalBeanConfigurerAspect, org.springframework.context.annotation.internalConfigurationAnnotationProcessor, org.springframework.contextnowtopuringworkationationoporotationationoprocessation. context.annotation.internalRequiredAnnotationProcessor, org.springframework.context.annotation.internalCommonAnnotationProcessor, enumInjectionComponent, rounding, org.springframework.context.annotation.ConfigurationClassPostProcessor.importAwareProcessor]; root from factory hierarchy
So I have a bean rounding in context.
What did I miss?
edit: I just found the problem with Spring version 3.1.x only, in 3.2.x it works, is there any workaround available?
edit2: here is the definition of beans
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 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 "> <context:spring-configured /> <context:annotation-config /> <context:component-scan base-package="net.betlista"/> <bean id="rounding" class="java.math.RoundingMode" factory-method="valueOf"> <constructor-arg value="UP" /> </bean> </beans>
Edit3:
as a workaround. I used the Dev Blanked traversal method to specify a list, and use @Value in my bean as
@Value("#{roundingModes[0]}") public RoundingMode roundingMode;
if there is a better (nicer) solution I would like to see -)
