Question

我正在尝试使用spring-data-cassandra（1.2.0.BUILD-SNAPSHOT）创建一个独立的应用程序。尝试创建应用程序上下文时使用新的ClassPathXmlApplicationContext（＆＃34; context.xml＆＃34;）＆＃39;抛出以下异常（我的context.xml是here）

欣赏我做错的任何提示。

Answer 1

据我说，Spring无法找到名为bean的cqlTemplate。你必须在春天的背景下创造相同的东西。您可以按照以下链接进行XML配置（第4.3.2节）。 http://docs.spring.io/spring-data/cassandra/docs/1.0.1.RELEASE/reference/html/cassandra.core.html

Answer 2

我使用了来自there的配置（示例7）：

<!-- Loads the properties into the Spring Context and uses them to fill
in placeholders in the bean definitions -->
<context:property-placeholder location="classpath:cassandra.properties" />

<!-- REQUIRED: The Cassandra Cluster -->
<cassandra:cluster contact-points="${cassandra.contactpoints}"
port="${cassandra.port}" />

<!-- REQUIRED: The Cassandra Session, built from the Cluster, and attaching
to a keyspace -->
<cassandra:session keyspace-name="${cassandra.keyspace}" />

<!-- REQUIRED: The Default Cassandra Mapping Context used by CassandraConverter -->
<cassandra:mapping>
  <cassandra:user-type-resolver keyspace-name="${cassandra.keyspace}" />
</cassandra:mapping>

<!-- REQUIRED: The Default Cassandra Converter used by CassandraTemplate -->
<cassandra:converter />

<!-- REQUIRED: The Cassandra Template is the building block of all Spring
Data Cassandra -->
<cassandra:template id="cassandraTemplate" />

<!-- OPTIONAL: If you are using Spring Data for Apache Cassandra Repositories, add
your base packages to scan here -->
<cassandra:repositories base-package="org.spring.cassandra.example.repo" />

并得到了相同的错误，直到我通过主应用程序类中的注释@EnableCassandraRepositories启用了cassandra存储库。它类似于：

@SpringBootApplication
@ImportResource("classpath:app-integration.xml")
@EnableCassandraRepositories
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

无法解析对bean的引用＆＃39; cqlTemplate＆＃39;同时设置bean属性＆cassandraTemplate＆＃39;
