正在为 MongoTemplate 执行构造函数依赖导致错误 org.springframework.beans.factory.UnsatisfiedDependencyException:Error creating bean with name 'mongoTemplate'
这里是配置代码
@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;
}
}
问题是MongoTemplate的构造函数依赖引起的，不知道怎么解决，
我试过@Autowired，没有解决同样的问题。

您似乎没有为“MongoTemplate”创建的 bean
为其创建一个 bean 并使用它来为 Mongobee 设置 MongoTemplate。
下面是这样做的例子
@Bean
public MongoClient mongo() {
return new MongoClient("localhost");
}
@Bean
public MongoTemplate mongoTemplate() throws Exception {
return new MongoTemplate(mongo(), "test");
}
然后使用这个
@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项，以后您可以在需要 MongoTemplate 的任何地方使用
@Autowired
MongoTemplate mongoTemplate;
希望这能解决您的问题！！
在这里，
@Bean
public MongoClient mongo() {
return new MongoClient("localhost");
}
Spring数据MongoDB的版本SpringBoot 2.3使用Mongo驱动程序的版本4，但Mongobee依赖于在版本 3 上。这两个版本具有不同的 Maven 坐标（组 ID 和工件 ID），因此您最终会在类路径中找到它们。这会导致驱动程序版本 4 中的一些代码使用版本 3 中的代码和 NoSuchFieldError 结果。
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'
}
您 运行 遇到新版本 Spring Data MongoDB, and the one used by mongobee 所需的 MongoDB Java 驱动程序之间的不兼容性。 Spring 数据 MongoDB 需要 Mongo Java 库的第 4 版，而 mongobee 需要第 3 版。这两个版本彼此不兼容，不能在内部同时使用一个应用程序。
种种迹象表明，mongobee 已被其创建者放弃，最后一次提交是在 2018 年 3 月，此后创建者没有对问题做出任何回应。因此，不要指望发布该库的更新版本以支持新版本的 Mongo Java 驱动程序。
由于这个项目的放弃，从 mongobee 派生了几个后续库。据我所知，Mongock 是唯一剩下的积极维护的后继库。它支持 Mongo Java 库的第 3 版和第 4 版。
Mongock 是 Mongo 蜜蜂的一次重大进化，其中 built-in support for migrating from mongobee。除了 built-in 支持第 4 版 Mongo Java 驱动程序之外，它还有可选的 built-in 与 Spring & Spring Boot 的集成。
因此，如果您希望将最新版本的 Spring Data MongoDB 与 mongobee-compatible 迁移库一起使用，Mongock 将是最简单的, 最直接的方法。
