在类路径资源Mongobee中创建名为“mongoTemplate”的bean时出错

Question

使用Mongobee进行数据迁移创建和错误作为Error creating bean with name 'mongoTemplate' defined in class path resource

迁移配置

@Configuration
public class ProductMigration {
    private final Environment environment;
    private final 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;
    }
}

变更日志

@ChangeLog(order = "001")
public class DbChangeLog001 {
    @ChangeSet(order = "001", id = "seedProduct", author = "San")

    public void seedProductMember(MongoTemplate mongoTemplate) {
        mongoTemplate.insert(new Product());
    }
}

Answer 1

堆栈跟踪非常直接，看起来mongo客户端bean没有被创建，这反过来又没有创建mongo模板bean，因为代码无法为mongo客户端找到一个适当的构造函数，其中包含您提供的参数数。

Caused by: org.springframework.beans.BeanInstantiationException: Failed to instantiate [com.mongodb.client.MongoClient]: Factory method 'mongo' threw exception; nested exception is java.lang.NoSuchFieldError: UNSPECIFIED

检查您的配置，并确保mongo所需的所有字段(如数据库、url等)都得到了正确的解析，并且您正在正确配置bean。请共享您的配置以获得更多的analysis.Since --您正在使用springboot mongo启动器来自动配置所有内容，确保您在application.yml或application.properties中提供了所有必要的数据，例如，如果您的本地mongo停靠程序使用一个单独的端口而不是默认端口，或者有一个用户名和密码用于登录：

spring.data.mongodb.authentication-database=admin
spring.data.mongodb.username=root
spring.data.mongodb.password=root
spring.data.mongodb.database=databasename
spring.data.mongodb.port=27017
spring.data.mongodb.host=localhost
