我编写了一个自定义保存查询,以便可以在每个项目上添加可配置的TTL。这是我的仓库:

@Repository
public interface MyCassandraRepository extends
                                         TypedIdCassandraRepository<MyCassandraItem, UUID> {

    @Query("insert into " + TABLE_NAME + " (" + CQL_UUID + ", " + CQL_PLAN + ") values (?0, ?1) using ttl ?2")
    MyCassandraItem customSaveWithTtl(UUID uuid, String plan, Integer ttl);
}


这是我的桌子:

CREATE TABLE IF NOT EXISTS my_users.plans (
   user_id uuid,
   plan text,
   PRIMARY KEY (user_id)
) ;


但是,当我尝试添加一个计划字符串包含句号/句点(例如eyJhbGciOiJIUzUxMiJ9.hsdyu7832uwhjjdsjkdsew2389dhj)的条目时,出现以下错误:

org.springframework.cassandra.support.exception.CassandraQuerySyntaxException: line 1:110 mismatched input 'eyJhbGciOiJIUzUxMiJ9' expecting ')' (...plan) values ('c7a8fd65-8ef5-420e-b02e-898fe248bbf3', ''[eyJhbGciOiJIUzUxMiJ9]....); nested exception is com.datastax.driver.core.exceptions.SyntaxError: line 1:110 mismatched input 'eyJhbGciOiJIUzUxMiJ9' expecting ')' (...plan) values ('c7a8fd65-8ef5-420e-b02e-898fe248bbf3', ''[eyJhbGciOiJIUzUxMiJ9]....)

尝试使用CQLSH手动添加它时,我也收到“。”错误:

SyntaxException: line 1:826 no viable alternative at input '.' (... "plan") VALUES (c7a8fd65-8ef5-420e-b02e-898fe248bbf3, [eyJhbGciOiJIUzUxMiJ9].hsdyu7832uwhjjdsjkdse...)

有人能看到我如何获得它来添加整个String而不只是停在'。'上吗?

最佳答案

您可以尝试使用PreparedStatement

String originalPlan = "eyJhbGciOiJIUzUxMiJ9.hsdyu7832uwhjjdsjkdsew2389dhj";
PreparedStatement preparedStatement = cqlTemplate.getSession().prepare("insert into plans (user_id, plan) values (?, ? )");
Statement insertStatement = preparedStatement.bind(UUIDs.timeBased(), originalPlan );
cqlTemplate.execute(insertStatement);
