Question

我使用spring 4和spring mongo数据1.7和mongo-java-driver 3.2.1。

我在tomcat启动时收到附加错误。

根据SO的建议，我多次重新编写代码，但没有成功。

我可以使用小型测试代码在侧弹簧上连接相同的mongo。

请建议。

提前感谢一百万。

Pom.xml

<dependency>
        <groupId>org.mongodb</groupId>
        <artifactId>mongo-java-driver</artifactId>
        <version>3.2.1</version>
    </dependency>
    <dependency>
        <groupId>org.springframework.data</groupId>
        <artifactId>spring-data-mongodb</artifactId>
        <version>1.7.0.RELEASE</version>
    </dependency>

Java配置文件

@Bean(name = {"mongoTemplate"})
    public MongoTemplate getMongoTemplate() throws UnknownHostException {
        MongoTemplate mongoTemplate = new MongoTemplate(getMongoDbFactory(), getMongoConverter());
        mongoTemplate.setWriteConcern(WriteConcern.SAFE);
        checkDBConnection(mongoTemplate);
        return mongoTemplate;
    }

    @Bean
    public MongoConverter getMongoConverter() throws UnknownHostException {
        MappingMongoConverter mongoConverter = new MappingMongoConverter(new DefaultDbRefResolver(getMongoDbFactory()), new MongoMappingContext());
        mongoConverter.setMapKeyDotReplacement(MAP_KEY_DOT_REPLACEMENT);
        return mongoConverter;
    }

    @Bean(name = {"mongoDbFactory"})
    public MongoDbFactory getMongoDbFactory() throws UnknownHostException {
        return new SimpleMongoDbFactory(new MongoClient(host, port), databaseName);
    }

错误发生在：

new MongoClient(host, port);

带值

new MongoClient("127.0.0.1", 27017);

如果我是正确的，他们都有自己的BSON定义，并且都使用不同的版本导致你的java.lang.IncompatibleClassChangeError异常

请参阅https://github.com/mongodb/mongo-java-driver/blob/master/driver/src/main/com/mongodb/DBDecoder.java

您已在POM中指定使用mongo驱动程序的3.2.1版本，并在弹簧库中使用版本2.1.13

https://github.com/spring-projects/spring-data-mongodb/blob/1.7.x/pom.xml

IncompatibleClassChangeError：使用spring mongo数据创建mongo客户端实例时的com / mongodb / DefaultDBDecoder
