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

有没有人尝试在spring-boot中禁用mongodb的自动配置？

我正在尝试使用spring-data-mongodb进行spring-boot; 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spring-data-mongodb（尝试过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。 由于我连接到多个服务器，因此我不需要自动配置单个默认的MongoTemplate和GridFsTemplate bean。

我的主要课程如下：

@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); } } 

我的两个mongo配置类看起来像这样：

 @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()); } } 

有了这个设置一切正常。 如果我从mongoDbFactory1和template1 bean中删除@Primary注释，应用程序将失败，但似乎没有禁用自动配置的exception。 下面列出了exception消息：

Answer 1

正如Andy Wilkinson在评论中指出的那样，当使用带排除列表的EnableAutoConfiguration时，请确保没有其他类使用EnableAutoConfiguration或SpringBootApplication进行注释。

Answer 2

我是这样做的：

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

Answer 3

我的用例略有不同。 我在同一个项目中需要2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 options, Environment environment) { super(properties,options,environment); } } 

和

 @Profile("mongo") @Configuration @EnableConfigurationProperties(MongoProperties.class) public class CustomMongoDataAutoConfiguration extends MongoDataAutoConfiguration { public CustomMongoDataAutoConfiguration( ApplicationContext applicationContext, MongoProperties properties) { super(applicationContext,properties); } } 

Answer 4

尝试在调试模式下运行应用程序。 当MongoDB依赖的混淆试图实例化但相应的bean不存在时，就会发生这种情况。 在我的例子中，我已经排除了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 { //... }
