在spring mongo中使用Mongobee进行迁移

代码语言：javascript
运行
复制
 plugins {
    id 'org.springframework.boot' version '2.3.1.RELEASE'
    id 'io.spring.dependency-management' version '1.0.9.RELEASE'
    id 'java'
}

group = 'fete.bird'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '14'
compileJava {
    options.compilerArgs += ["--enable-preview"]
}
repositories {
    mavenCentral()
}
ext {
    set('springCloudVersion', "Hoxton.SR6")
}

dependencies {
    implementation 'org.springframework.boot:spring-boot-starter'
    testImplementation('org.springframework.boot:spring-boot-starter-test') {
        exclude group: 'org.junit.vintage', module: 'junit-vintage-engine'
    }
    implementation 'org.springdoc:springdoc-openapi-ui:1.4.3'
    implementation 'org.springframework.cloud:spring-cloud-starter-netflix-eureka-client'
    implementation 'org.springframework.boot:spring-boot-starter-actuator'
    developmentOnly 'org.springframework.boot:spring-boot-devtools'
    implementation 'org.springframework.cloud:spring-cloud-starter-config'
    implementation 'org.springframework.boot:spring-boot-starter-data-mongodb'

    compile 'com.github.mongobee:mongobee:0.13'
}
dependencyManagement {
    imports {
        mavenBom "org.springframework.cloud:spring-cloud-dependencies:${springCloudVersion}"
    }
}

test {
    useJUnitPlatform()
}

对导致错误org.springframework.beans.factory.UnsatisfiedDependencyException:Error creating bean with name 'mongoTemplate'的MongoTemplate执行构造函数依赖

以下是配置代码

代码语言：javascript
运行
复制
@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;
    }
}

这个问题是由MongoTemplate的构造函数依赖引起的，但是不知道如何解决这个问题。

我试过@Autowired，但不能解决同样的问题。

Spring Boot2.3中包含的Spring Data MongoDB版本使用Mongo的驱动程序版本4，但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)，因此您最终会在类路径中同时使用它们。这导致驱动程序版本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'

看起来你还没有为"MongoTemplate“创建bean

为它创建一个bean，并使用它为Mongobee创建setMongoTemplate。

下面是这样做的示例

代码语言：javascript
运行
复制
@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

代码语言：javascript
运行
复制
@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，以后只要需要MongoTemplate，就可以使用

代码语言：javascript
运行
复制
 @Autowired  
 MongoTemplate mongoTemplate;

希望，这将解决你的问题!！

您遇到了较新版本的MongoDB所需的Spring Data MongoDB Java驱动程序与mongobee使用的驱动程序不兼容的问题。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，不能在应用程序中同时使用。

所有迹象表明，mongobee已经被其创建者抛弃，最后一次提交是在2018年3月，从那时起，创建者没有对问题做出任何回应。因此，不要期望发布该库的更新版本时会支持新版本的Mongo Java驱动程序。

由于这个项目的放弃，从mongobee派生了几个后继库。根据我所能确定的，Mongock是仅存的积极维护的后继库。它同时支持Mongo Java库的版本3和版本4。

Mongock是带有built-in support for migrating from mongobee的Mongobee的重要进化。除了对Mongo Java驱动程序版本4的内置支持外，它还具有与Spring & Spring Boot的可选内置集成。

因此，如果您希望使用与MongoDB兼容的迁移库的最新版本的Spring Data Mongock，Mongock将是最简单、最直接的方法。

dependencies {
    [...]

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