插入过程中未配置的列误差

Question

我有以下用户信息对象映射到我的Keyspace" data_collection"中的表" user_info"。我在Cassandra数据库中创建了" User_info"表。我正在使用弹簧数据Cassandra与Java的Cassandra数据库连接，以及下面的弹簧注释。

@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;
    }
}

我正在使用以下代码将记录插入我的" user_info"表中。

    @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工作正常工作，而在插入过程中，我会得到以下例外。我清楚地将UserInfo.java类映射到了表名称为" user_info"，使用上面的注释。我不知道为什么插入插件试图发生在" UserInfo"表中。

org.springframework.cassandra.support.exception.CassandraInvalidQueryException: unconfigured columnfamily userinfo; nested exception is com.datastax.driver.core.exceptions.InvalidQueryException: unconfigured columnfamily userinfo

    at org.springframework.data.cassandra.core.CassandraTemplate.update(CassandraTemplate.java:537)
    at org.springframework.data.cassandra.core.CassandraTemplate.update(CassandraTemplate.java:532)

请在Cassandra中的表格描述下面找到。

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：我刚刚尝试保存另一个类Test.java。它被映射到表" test_info"表。我有以下错误

org.springframework.cassandra.support.exception.CassandraInvalidQueryException: unconfigured columnfamily test; nested exception is com.datastax.driver.core.exceptions.InvalidQueryException: unconfigured columnfamily test

at org.springframework.data.cassandra.core.CassandraTemplate.insert(CassandraTemplate.java:285)

我只是想知道我的Java班级名称和Cassandra中的表名是否应该始终相同。因为它在@Table注释中指定的列而不是" test_info"列"测试"。

以下是我的键空间的描述

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

编辑 - 已解决：我根据与@pinkpanther的对话找到了解决方案。我曾导入com.datastax.driver.mapping.annotations.table而不是org.springframework.data.cassandra.mapping.table，这就是为什么它不符合表名称映射的原因。感谢您的帮助。

问题可能在于表的套件导入，弹簧数据cassandra需要org.springframework.data.cassandra.mapping.Table。用它替换导入的com.datastax.driver.mapping.annotations.Table。
