如何在spring-boot中禁用spring-data-mongodb autoconfiguration
作者:互联网
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.我还导入了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,并显示一个似乎尚未禁用自动配置的异常.下面列出了异常消息:

解决方法:
我是这样做的:
@SpringBootApplication(exclude = {MongoAutoConfiguration.class, MongoDataAutoConfiguration.class})
