Spring 使用 Cassandra 3.x 驱动程序启动

Question

我用Spring开机1.3.8.RELEASE。为了使用 cassandra 3.x 驱动程序，我尝试了类似下面的方法；

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-cassandra</artifactId>
        <exclusions>
            <exclusion>
                <groupId>org.springframework.data</groupId>
                <artifactId>spring-data-cassandra</artifactId>
            </exclusion>
        </exclusions>
    </dependency>
    <dependency>
        <groupId>org.springframework.data</groupId>
        <artifactId>spring-data-cassandra</artifactId>
        <version>1.4.0.RELEASE</version>
        <exclusions>
            <exclusion>
                <groupId>com.datastax.cassandra</groupId>
                <artifactId>cassandra-driver-core</artifactId>
            </exclusion>
            <exclusion>
                <groupId>com.datastax.cassandra</groupId>
                <artifactId>cassandra-driver-dse</artifactId>
            </exclusion>
        </exclusions>
    </dependency>
    <!-- https://mvnrepository.com/artifact/com.datastax.cassandra/cassandra-driver-core -->
    <dependency>
        <groupId>com.datastax.cassandra</groupId>
        <artifactId>cassandra-driver-core</artifactId>
        <version>3.1.0</version>
    </dependency>

但是我得到错误；

Caused by: java.lang.NoSuchMethodError: com.datastax.driver.core.DataType.asJavaClass()Ljava/lang/Class;
at org.springframework.data.cassandra.mapping.CassandraSimpleTypeHolder.<clinit>(CassandraSimpleTypeHolder.java:62) ~[spring-data-cassandra-1.4.0.RELEASE.jar:?]

我在 https://github.com/spring-projects/spring-boot/issues/5835 试过这个原因，有一个 post ;

Adopting the Cassandra 3 changes in Spring Data Cassandra 1.5 (Ingalls) does not impose breaking changes for Spring Boot. Tested the upgrade with Boot 1.3.3 and 1.4.0-SNAPSHOT.

不应该像上面那样吗？我哪里错了？

注意： 我正在尝试这个例子：https://github.com/spring-projects/spring-boot/tree/master/spring-boot-samples/spring-boot-sample-data-cassandra

Answer 1

spring-data-cassandra-1.4.0.RELEASE 取决于 <cassandra.version>2.1.11</cassandra.version> 和 <cassandra-driver-dse.version>2.1.7.1</cassandra-driver-dse.version> 参见 https://github.com/spring-projects/spring-data-cassandra/blob/1.4.0.RELEASE/pom.xml.

如果你想使用 Cassandra 3.x 你应该升级到 spring-boot 1.5.x 以受益于 spring-boot-starter-data-cassandra :1.5.x 取决于 <cassandra.version>3.0.0</cassandra.version> 和 <cassandra-driver.version>3.0.3</cassandra-driver.version> 请参阅 https://github.com/spring-projects/spring-data-cassandra/blob/1.5.0.M1/pom.xml

从 pom 文件中删除 Cassandra 驱动程序依赖项。 Spring 开机会提供正确的版本
