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

问题

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:

回答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

回答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.

回答3:

My use case was slightly different. I had a requirement for 2 different databases in the same project. I extended the auto configuration classes and added a profile annotation.

@Profile("mongo")
@Configuration
public class CustomMongoAutoConfiguration extends MongoAutoConfiguration {

    public CustomMongoAutoConfiguration(
        MongoProperties properties,
        ObjectProvider<MongoClientOptions> options,
        Environment environment) {
        super(properties,options,environment);
    }
}

And

@Profile("mongo")
@Configuration
@EnableConfigurationProperties(MongoProperties.class)
public class CustomMongoDataAutoConfiguration extends MongoDataAutoConfiguration {

    public CustomMongoDataAutoConfiguration(
        ApplicationContext applicationContext,
        MongoProperties properties) {
        super(applicationContext,properties);
    }

}

回答4:

Try to Run application in Debug mode. It happens when MongoDB dependant configaration is trying to instantiate but respective bean not present. In My case I have excluded MongoDataAutoConfiguration.class and MongoRepositoriesAutoConfiguration.class, to get the application run.

@SpringBootApplication @EnableAutoConfiguration(exclude={MongoAutoConfiguration.class, MongoRepositoriesAutoConfiguration .class,MongoDataAutoConfiguration.class}) public class SomeApplication { //... }
