将Mongobee与春季mongo一起使用

对MongoTemplate进行构造函数依赖会导致错误org.springframework.beans.factory.UnsatisfiedDependencyException:Error creating bean with name 'mongoTemplate'

这是配置代码

@Configuration
public class ProductMigration {
    private final Environment environment;
    private MongoTemplate mongoTemplate;
    private static final Logger logger = LoggerFactory.getLogger(FeteBirdProductApplication.class);

    public ProductMigration(Environment environment, MongoTemplate mongoTemplate) {
        this.environment = environment;
        this.mongoTemplate = mongoTemplate;
    }

    @Bean
    public Mongobee mongobee(){
        logger.info("Starting product migration ...");
        String mongoUri = environment.getProperty("spring.data.mongodb.uri");
        boolean migrationsEnabled = Boolean.parseBoolean(environment.getProperty("app.db.migrations.enabled"));
        Mongobee runner = new Mongobee(mongoUri);
        runner.setEnabled(migrationsEnabled);
        runner.setChangeLogsScanPackage("fete.bird.fetebirdproduct.migration");
        runner.setChangelogCollectionName("migrations");
        runner.setLockCollectionName("migrations_lock");
        runner.setMongoTemplate(this.mongoTemplate);
        logger.info("Product migration completed...");
        return runner;
    }
}

此问题是由MongoTemplate的构造函数依赖性引起的，但不知道如何解决该问题，

我尝试了@Autowired，但没有解决同样的问题。

Spring Boot 2.3中包含的Spring Data MongoDB版本使用Mongo驱动程序的版本4，但是Mongobee依赖于版本3。这两个版本具有不同的Maven坐标（组ID和工件ID），因此您最终都会得到它们在类路径上。这会使用版本3中的代码生成驱动程序版本4中的某些代码，并显示NoSuchFieldError。

您可以通过从Mongobee依赖项中排除Mongo驱动程序来避免此问题：

compile('com.github.mongobee:mongobee:0.13') {
    exclude group: 'org.mongodb'
}

似乎您没有为“ MongoTemplate”创建Bean

为此创建一个bean，并将其用于为Mongobee设置setMongoTemplate。

下面是这样做的示例

@Bean
public MongoClient mongo() {
    return new MongoClient("localhost");
}

@Bean
public MongoTemplate mongoTemplate() throws Exception {
   return new MongoTemplate(mongo(), "test");
}

然后使用此

@Bean
public Mongobee mongobee(){
    logger.info("Starting product migration ...");
    String mongoUri = environment.getProperty("spring.data.mongodb.uri");
    boolean migrationsEnabled = Boolean.parseBoolean(environment.getProperty("app.db.migrations.enabled"));
    Mongobee runner = new Mongobee(mongoUri);
    runner.setEnabled(migrationsEnabled);
    runner.setChangeLogsScanPackage("fete.bird.fetebirdproduct.migration");
    runner.setChangelogCollectionName("migrations");
    runner.setLockCollectionName("migrations_lock");
    runner.setMongoTemplate(mongoTemplate());
    logger.info("Product migration completed...");
    return runner;
}

现在，您不必使用构造函数依赖关系，以后便可以在需要MongoTemplate的任何地方使用

 @Autowired  
 MongoTemplate mongoTemplate;

希望，这将解决您的问题！！

您正在遇到Spring Data MongoDB较新版本所需的MongoDB Java驱动程序与mongobee使用的驱动程序之间的不兼容性。 Spring Data MongoDB需要Mongo Java库的版本4，而mongobee需要版本3。这两个版本彼此不兼容，并且不能在应用程序中同时使用。

从所有迹象看，mongobee已被其创建者抛弃，最后一次提交是在2018年3月进行的，此后创建者未对问题做出任何回应。因此，不要期望该库的更新版本能够支持新版本的Mongo Java驱动程序。

由于此项目的放弃，从mongobee派生了几个后继库。根据我的判断，Mongock是唯一剩下的活跃维护的后继库。它同时支持Mongo Java库的版本3和版本4。

Mongock是Mongobee的一个重大改进，其built-in support for migrating from mongobee。除了对Mongo Java驱动程序版本4的内置支持之外，它还具有与Spring＆Spring Boot的可选内置集成。

因此，如果您希望将Spring Data MongoDB的最新版本与兼容mongobee的迁移库一起使用，则Mongock将成为最简单，最直接的方法。

dependencies {
    [...]

    compile 'com.github.cloudyrock.mongock:mongock-api:4.1.14'
}

在这里，

@Bean
public MongoClient mongo() {
    return new MongoClient("localhost");
}
