Resolve ServiceConfigurationError when adding Togglz to Spring Boot application

Question

I'm trying to implement Togglz in my Spring Boot application.

I followed the Quick Start steps but when I run my application I get this exception:

Exception in thread "main" java.util.ServiceConfigurationError: org.togglz.core.spi.BeanFinder: org.togglz.cdi.spi.CDIBeanFinder Unable to get public no-arg constructor at java.base/java.util.ServiceLoader.fail(ServiceLoader.java:586) at java.base/java.util.ServiceLoader.getConstructor(ServiceLoader.java:679) at java.base/java.util.ServiceLoader$LazyClassPathLookupIterator.hasNextService(ServiceLoader.java:1240) at java.base/java.util.ServiceLoader$LazyClassPathLookupIterator.hasNext(ServiceLoader.java:1273) at java.base/java.util.ServiceLoader$2.hasNext(ServiceLoader.java:1309) at java.base/java.util.ServiceLoader$3.hasNext(ServiceLoader.java:1393) at org.togglz.core.context.BeanFinderFeatureManagerProvider.getFeatureManager(BeanFinderFeatureManagerProvider.java:36) at org.togglz.core.context.FeatureContext.findFeatureManagerInClassLoader(FeatureContext.java:107) at org.togglz.core.context.FeatureContext.getFeatureManagerOrNull(FeatureContext.java:73) at org.togglz.core.context.FeatureContext.getFeatureManager(FeatureContext.java:46) at com.paulcarron.testproject.MyFeatures.isActive(MyFeatures.java:18) at com.paulcarron.testproject.TogglzTest.getTogglzStatus(TogglzTest.java:31) at com.paulcarron.testproject.TestprojectApplication.main(TestprojectApplication.java:15) Caused by: java.lang.NoClassDefFoundError: javax/enterprise/context/spi/Contextual at java.base/java.lang.Class.getDeclaredConstructors0(Native Method) at java.base/java.lang.Class.privateGetDeclaredConstructors(Class.java:3405) at java.base/java.lang.Class.getConstructor0(Class.java:3610) at java.base/java.lang.Class.getConstructor(Class.java:2303) at java.base/java.util.ServiceLoader$1.run(ServiceLoader.java:666) at java.base/java.util.ServiceLoader$1.run(ServiceLoader.java:663) at java.base/java.security.AccessController.doPrivileged(AccessController.java:569) at java.base/java.util.ServiceLoader.getConstructor(ServiceLoader.java:674) ... 11 more Caused by: java.lang.ClassNotFoundException: javax.enterprise.context.spi.Contextual at java.base/jdk.internal.loader.BuiltinClassLoader.loadClass(BuiltinClassLoader.java:641) at java.base/jdk.internal.loader.ClassLoaders$AppClassLoader.loadClass(ClassLoaders.java:188) at java.base/java.lang.ClassLoader.loadClass(ClassLoader.java:521) ... 19 more

This is my code in TogglzTest:

if(MyFeatures.FEATURE_ONE.isActive() ) {
    System.out.println("togglzOff is " + togOnTrue);
    System.out.println("togglzOff is " + togOnFalse);
}

Here is my isActive method in MyFeatures:

public boolean isActive() {
    return FeatureContext.getFeatureManager().isActive(this);
}

I did some Googling and all I can find was various dependencies that I should add but doing so doesn't resolve my issue. Here's my pom:

How do I resolve this?

Answer 1

The current milestone 4.0.0-M3 is compatible with Spring Boot 3 and I will release a final togglz 4.0.0 soon. Right now everything is working as expected so IMO you could also use the milestone release already.
