Description:
Parameter 0 of method lockProvider in com.guru.mythoughts.MythoughtsApplication required a bean of type 'com.couchbase.client.java.Bucket' that could not be found.
Action:
Consider defining a bean of type 'com.couchbase.client.java.Bucket' in your configuration.
I have given sample code and when I tried to run the application I am getting the above error. I have scheduled a method in controller and it should run for every 5 seconds. I have followed the above in the given below link https://gitcode.net/mirrors/lukas-krecan/ShedLock/-/tree/master/providers/couchbase
How can i solve this error?
Autowired the Cluster class and used the cluster to get the bucket details with bean creation in main class which return the bucket object. please see the same code and it is working fine.
@Autowired
Cluster cluster;
@Bean
public Bucket getBucket() {
return cluster.bucket("bucket");
}
}
