如何在 spring-boot 中禁用 spring-data-mongodb 自动配置

问题描述 投票：0回答：6

有人尝试过在 spring-boot 中禁用 mongodb 的自动配置吗？

我正在尝试使用 spring-boot 和 spring-data-mongodb；使用基于java的配置；使用 spring-boot 1.2.1.RELEASE，我导入 spring-boot-starter-web 及其父 pom 进行依赖管理。我还导入了 spring-data-mongodb （也尝试了 spring-boot-starter-mongodb ）。

我需要连接到两个不同的 MongoDB 服务器。所以我需要为 mongo 连接、MongoTemplate 等配置两组实例。 我还想禁用自动配置。由于我要连接到多个服务器，因此不需要自动配置单个默认 MongoTemplate 和 GridFsTemplate bean。

我的主课是这样的：

@Configuration
@EnableAutoConfiguration(exclude={MongoAutoConfiguration.class, MongoDataAutoConfiguration.class})
@ComponentScan
//@SpringBootApplication  
public class MainRunner {

    public static void main(String[] args) {
        SpringApplication.run(MainRunner.class, args);
    }
}

我的两个 mongo 配置类如下所示：

@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());
    }
}

和

@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());
    }
}

通过此设置一切正常。如果我从 mongoDbFactory1 和 template1 bean 中删除 @Primary 注释，应用程序将失败并出现似乎尚未禁用自动配置的异常。下面列出了异常消息：

我就是这样做的：

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

或按照Dan Oak的建议：

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

正如 Andy Wilkinson 在评论中指出的，在使用 EnableAutoConfiguration 和排除列表时，请确保没有其他类用 EnableAutoConfiguration 或 SpringBootApplication 注释。

我的用例略有不同。我需要在同一个项目中使用两个不同的数据库。我扩展了自动配置类并添加了配置文件注释。

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

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

还有

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

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

}

尝试在调试模式下运行应用程序。当 MongoDB 相关配置尝试实例化但相应的 bean 不存在时，就会发生这种情况。 就我而言，我已排除 MongoDataAutoConfiguration.class 和 MongoRepositoriesAutoConfiguration.class，以使应用程序运行。

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

Spring Boot 2.3.x：

spring.autoconfigure.exclude[0]: org.springframework.boot.autoconfigure.data.mongo.MongoDataAutoConfiguration
spring.autoconfigure.exclude[1]: org.springframework.boot.autoconfigure.data.mongo.MongoRepositoriesAutoConfiguration

反应式：

spring.autoconfigure.exclude[0]: org.springframework.boot.autoconfigure.data.mongo.MongoReactiveDataAutoConfiguration
spring.autoconfigure.exclude[1]: org.springframework.boot.autoconfigure.data.mongo.MongoReactiveRepositoriesAutoConfiguration

与 https://stackoverflow.com/a/45929916/5213837 与 https://stackoverflow.com/a/49980868/5213837相同，Spring boot 2.3/Kotlin

@SpringBootApplication(exclude = [MongoAutoConfiguration::class, MongoDataAutoConfiguration::class]

@Profile("mongo")
@Configuration
class CustomMongoAutoConfiguration: MongoAutoConfiguration() {
    override fun mongo(
        properties: MongoProperties?,
        environment: Environment?,
        builderCustomizers: ObjectProvider<MongoClientSettingsBuilderCustomizer>?,
        settings: ObjectProvider<MongoClientSettings>?
    ): MongoClient {
        return super.mongo(properties, environment, builderCustomizers, settings)
    }
}

@Profile("mongo")
@Configuration
@EnableConfigurationProperties(MongoProperties::class)
class CustomMongoDataAutoConfiguration : MongoDataAutoConfiguration()
