java.lang.IllegalAccessError: failed to access class com.mongodb.client.internal.MongoClientDelegate from class com.mongodb.Mongo
I am upgrading the spring boot version from 2.2.7.RELEASE to 2.6.7. In order to upgrade the spring boot i am using spring-data-mongodb version 2.2.12.RELEASE. With this dependency combination my code deployed successfully at my local but when i deploy the code at my SIT server it failed and throws the following error.

following is the bean config.
<bean id="mongoClientURI" class="com.web.config.MongoConfig"/>
<bean id="mongoFactory"
class="org.springframework.data.mongodb.core.SimpleMongoDbFactory">
<constructor-arg name="uri" ref="mongoClientURI"/>

Following is the mongoconfig
public class MongoConfig implements FactoryBean<MongoClientURI> {
private String uri;
@Value("${mongo_socketTimeout}")
private int socketTimeout;
@Value("${mongo_uri}")
public void setUri(String uri) {
this.uri = uri;
}
@Override
public MongoClientURI getObject() throws Exception {
return new MongoClientURI(uri, MongoClientOptions.builder().socketTimeout(socketTimeout));
}
@Override
public Class<?> getObjectType() {
return MongoClientURI.class;
}
@Override
public boolean isSingleton() {
return true;
}
}
Your help will be really appreciated.
It's not clear to me what this problem has to do with Spring Cloud Connectors. Connectors is used when you want connection beans automatically configured based on credentials exposed by a cloud platform, but you are configuring the MongoDB connection explicitly.
i am using spring-data-mongodb version 2.2.12.RELEASE
I would strongly recommend that you use the version of spring-data-mongodb that is managed by Spring Boot. For Spring Boot 2.6.7, this is org.springframework.data:spring-data-mongodb:3.3.4.
Closing due to inactivity. If you can provide a sample that reproduces the problem after addressing the concern in my comment above, we can consider re-opening the issue.
