Question

我将以下用户信息对象映射到表＆＃34; user_info＆＃34;在我的密钥空间＆＃34; data_collection＆＃34;。我创建了＆＃34; user_info＆＃34;我的cassandra数据库中的表。我使用spring数据cassandra连接到JAVA的cassandra数据库和弹簧注释如下。

@Table(name="user_info",keyspace="data_collection", caseSensitiveKeyspace = false,caseSensitiveTable = false)

public class UserInfo {
    @PartitionKey
    private UUID id;

    @PrimaryKeyColumn
    private String email;

    private int phone;

    private String name;

    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public String getEmail() {
        return email;
    }
    public void setEmail(String email) {
        this.email = email;
    }
    public int getPhone() {
        return phone;
    }
    public void setPhone(int phone) {
        this.phone = phone;
    }
}

我使用以下代码将记录插入我的＆＃34; user_info＆＃34;表

    @Autowired
    CassandraTemplate cassandraTemplate;

    public void saveUserInfo(UserInfo userInfo){
        logger.debug("userInfo "+new Gson().toJson(userInfo));
        String email = userInfo.getEmail();
        Select select = QueryBuilder.select().from("user_info");
        select.where(QueryBuilder.eq("email", email));
        logger.debug("Query "+select.toString());
        UserInfo existingUser = cassandraTemplate.selectOne(select, UserInfo.class);
       if(existingUser!=null){
            cassandraTemplate.update(userInfo);
       }
       else{
            cassandraTemplate.insert(userInfo);
       }

    }

我的selectOne正常工作，而在插入过程中我遇到以下异常。我已经清楚地将UserInfo.java类映射到表名＆＃34; user_info＆＃34;使用上面的注释。我不知道为什么插件试图发生在桌面上＃user;＆＃34;。

请在下面找到cassandra中表格的描述。

CREATE TABLE user_info (
  name text,
  email text,
  phone int
  PRIMARY KEY ((email))
) WITH
  bloom_filter_fp_chance=0.010000 AND
  caching='KEYS_ONLY' AND
  comment='' AND
  dclocal_read_repair_chance=0.100000 AND
  gc_grace_seconds=864000 AND
  index_interval=128 AND
  read_repair_chance=0.000000 AND
  replicate_on_write='true' AND
  populate_io_cache_on_flush='false' AND
  default_time_to_live=0 AND
  speculative_retry='99.0PERCENTILE' AND
  memtable_flush_period_in_ms=0 AND
  compaction={'class': 'SizeTieredCompactionStrategy'} AND
  compression={'sstable_compression': 'LZ4Compressor'};

快速更新：我刚尝试保存另一个类Test.java。它被映射到一个表＆＃34; test_info＆＃34;。我收到以下错误

我只是想知道我的Java类名和cassandra中的表名是否应该始终相同。因为它寻找的是柱状家族＆＃34;测试＆＃34;而不是＆＃34; test_info＆＃34;我在@Table注释中指定的。

以下是我的密钥空间的描述

CREATE KEYSPACE data_collection WITH replication = {
  'class': 'SimpleStrategy',
  'replication_factor': '3'
};

编辑 - 已解决： 我找到了基于与@pinkpanther对话的解决方案。我导入了com.datastax.driver.mapping.annotations.Table而不是org.springframework.data.cassandra.mapping.Table，这就是为什么它不尊重表名映射。谢谢你的帮助。

问题可能在于Table的包导入，Spring Data Cassandra需要org.springframework.data.cassandra.mapping.Table。用它替换导入的com.datastax.driver.mapping.annotations.Table。
