How to disable spring-data-mongodb autoconfiguration in spring-boot

Question

Has anyone tried disabling autoconfiguration for mongodb in spring-boot?

I am trying out spring-boot with spring-data-mongodb; Using java based configuration; Using spring-boot 1.2.1.RELEASE, I import spring-boot-starter-web and its' parent pom for dependency management. I also import spring-data-mongodb (tried spring-boot-starter-mongodb as well).

I need to connect to two different MongoDB servers. So I need to configure two sets of instances for mongo connection, MongoTemplate etc. I also want to disable auto-configuration. Since I am connecting to multiple servers, I don't need to have a single default MongoTemplate and GridFsTemplate bean autoconfigured.

My main class looks like this:

@Configuration @EnableAutoConfiguration(exclude={MongoAutoConfiguration.class, MongoDataAutoConfiguration.class}) @ComponentScan //@SpringBootApplication // @Configuration @EnableAutoConfiguration @ComponentScan  public class MainRunner {      public static void main(String[] args) {         SpringApplication.run(MainRunner.class, args);     } } 

My two mongo configuration classes look like this:

@Configuration @EnableMongoRepositories(basePackageClasses = {Test1Repository.class},         mongoTemplateRef = "template1",         includeFilters = {@ComponentScan.Filter(type = FilterType.REGEX, pattern = ".*Test1Repository")} ) public class Mongo1Config {      @Bean     public Mongo mongo1() throws UnknownHostException {         return new Mongo("localhost", 27017);     }      @Primary     @Bean     public MongoDbFactory mongoDbFactory1() throws UnknownHostException {         return new SimpleMongoDbFactory(mongo1(), "test1");     }      @Primary     @Bean     public MongoTemplate template1() throws UnknownHostException {         return new MongoTemplate(mongoDbFactory1());     } } 

and

@Configuration @EnableMongoRepositories(basePackageClasses = {Test2Repository.class},         mongoTemplateRef = "template2",         includeFilters = {@ComponentScan.Filter(type = FilterType.REGEX, pattern = ".*Test2Repository")} ) public class Mongo2Config {      @Bean     public Mongo mongo2() throws UnknownHostException {         return new Mongo("localhost", 27017);     }      @Bean     public MongoDbFactory mongoDbFactory2() throws UnknownHostException {         return new SimpleMongoDbFactory(mongo2(), "test2");     }      @Bean     public MongoTemplate template2() throws UnknownHostException {         return new MongoTemplate(mongoDbFactory2());     } } 

With this setup everything works. If I remove @Primary annotations from mongoDbFactory1 and template1 beans, application will fail with an exception that seems like autoconfiguration hasn't been disabled. Exception message is listed below:

Answer 1

This is how I do it:

@SpringBootApplication(exclude = {   MongoAutoConfiguration.class,    MongoDataAutoConfiguration.class }) 

or as suggested by Dan Oak:

spring.autoconfigure.exclude= \   org.springframework.boot.autoconfigure.mongo.MongoAutoConfiguration,\   org.springframework.boot.autoconfigure.data.mongo.MongoDataAutoConfiguration 

Answer 2

As pointed out by Andy Wilkinson in comments, when using EnableAutoConfiguration with exclude list make sure there are no other classes annotated with EnableAutoConfiguration or SpringBootApplication.
