我想编写Spring Boot代码以有条件地从mongoDB提取数据

Question

我能够使用以下代码从MongoDB中获取数据，但我想将这些数据从CommandLineRunner运行器公开给其他类。

@Repository
public interface ToolsDao extends MongoRepository< Tools, String> {
     public List<Tools> findByRegistries_active(boolean active);
}

此外，我已经编写了与构造方法的getter和setter一样的类。

public class Tools{

    @Id
    private String id;
    private String type;
    private List<Registries> registries;

对于注册管理机构，

public class Registries {

    private String name;
    private String url;
    private String secret;
    private boolean active;

@Bean
CommandLineRunner runner(ToolsDao toolsDao) {
    return new CommandLineRunner() {
        @Override
        public void run(String... args) throws Exception {
            Registries activeRegistry = null;
            Iterable<Tools> toolsList= toolsDao.findByRegistries_active(true);
            System.out.println("Configuration : ");

            for (Tools tools : toolsList) {
                for (Registries registry : config.getRegistries()) {
                    if(registry.getActive()) {
                        activeRegistry = registry;
                        break;
                    }
                }
            }

            System.out.println("active registry name is " + activeRegistry.getName());
            System.out.println("active registry url " + activeRegistry.getRegistryUrl());

        }
    };
}

我在上面的函数中得到输出，但是如果我想在任何其他函数中使用它，那么它将给出空值。

public class RegistryController2 {
@Autowired
ToolsDao toolsDao;
public Registries getData() {
    Registries activeRegistry = null;
    Iterable<Tools> personList = toolsDao.findByRegistries_active(true);
    System.out.println("Configuration : ");

    for (Tools tools : toolsList) {
        for (Registries registry : tools.getRegistries()) {
            if(registry.getActive()) {
                activeRegistry = registry;
                break;
            }
        }
    }

    System.out.println("active registry name is " + activeRegistry.getName());
    System.out.println("active registry url " + activeRegistry.getRegistryUrl());
}

MongoDB数据库：

Given below is MongoDB Collection from database test. and collection name is switchrepo.

"_id" : "1234567890",
    "type" : "toolss",
    "registreis" : [ 
        {
            "name" : "test",
            "url" : "test1",
            "secret" : "secret",
            "active" : true
        }, 
        {
            "name" : "test2",
            "url" : "test12",
            "secret" : "secret2",
            "active" : false
        }
    ]
}
