Java 如何在spring引导中禁用spring数据mongodb自动配置

有人试过在spring boot中禁用mongodb的自动配置吗

我正在试用SpringDataMongoDB的SpringBoot；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以进行依赖关系管理。我还导入了spring数据mongodb（也尝试了spring启动程序mongodb）

我需要连接到两个不同的MongoDB服务器。因此，我需要为mongo connection、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，因此不需要自动配置单个默认MongoTemplate和GridFSTemplatebean。

我的主要课程是这样的：

@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);
    }
}

@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());
    }
}

我的两个mongo配置类如下所示：

@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);
    }
}

@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());
    }
}

及

在这种设置下，一切正常。若我从mongoDbFactory1和Template1bean中删除@Primary注释，应用程序将失败，出现一个异常，看起来自动配置并没有被禁用。异常消息如下所示：

正如Andy Wilkinson在评论中指出的，当使用带有排除列表的EnableAutoConfiguration时，确保没有其他类用EnableAutoConfiguration或SpringBootApplication注释。

我的用例略有不同。我在同一个项目中需要两个不同的数据库。我扩展了自动配置并添加了一个纵断面注释

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

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

我就是这样做的：

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

或根据以下建议：

尝试在调试模式下运行应用程序。当依赖MongoDB的配置试图实例化但相应的bean不存在时，会发生这种情况。 在我的例子中，我已经排除了MongoDataAutoConfiguration.class和MongorPositioneSautoConfiguration.class，以运行应用程序

@springboot应用程序
@EnableAutoConfiguration（排除={MongoAtoConfiguration.class，MongoRepositoriesAutoConfiguration.class，MongoDataAutoConfiguration.class}）
公共类应用程序{
//...
}

与弹簧靴2.3/Kotlin相同

@SpringBootApplication（排除=[MongoAtoConfiguration:：class，MongoDataAutoConfiguration:：class]

@Profile（“mongo”）
@配置
类CustomMongoutoAtoConfiguration:MongoutoAtoConfiguration（）{
蒙哥(
属性：MongoProperties？，
环境：环境？，
BuilderCustomizer:对象提供程序？，
设置：ObjectProvider？
)：MongoClient{
返回super.mongo（属性、环境、builderCustomizers、设置）
}
