有人尝试禁用spring-boot中mongodb的自动配置吗?
我正在尝试使用基于Java的配置进行spring-boot和spring-data-mongodb的开发;使用spring-boot 1.2.1.RELEASE,并导入spring-boot-starter-web及其父POM以进行依赖管理。我还导入了spring-data-mongodb(尝试过spring-boot-starter-mongodb)。
我需要连接两个不同的MongoDB服务器。因此,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,所以不需要自动配置单个默认的MongoTemplate和GridFsTemplate bean。
我的主类如下:
@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MongoDB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());
}
}
使用这个配置,一切都正常。如果我从mongoDbFactory1和template1 bean中删除@Primary注解,则应用程序将失败,并出现一个异常消息,似乎自动配置没有被禁用。异常消息如下:
