What is a simple way to read from a Oracle DataBase and write to a text file, not using Spring Batch (but using Java)? Too complicated for Spring Batch.

• jOOQ

  93 5,882 9.8 Java

  jOOQ is the best way to write SQL in Java

  

There are also attempts to write queries in another DSL than the already commonly known and accepted SQL (or JPQL and Criteria API with the JPA specification/standard). One prominent candidate would be jooq: https://www.jooq.org/

• Spring Data JPA

  21 2,893 9.1 Java

  Simplifies the development of creating a JPA-based data access layer.

  

"Spring Batch" is not the Spring technology to access databases conveniently. That would be "Spring Data" or even "Spring Data JPA": https://spring.io/projects/spring-data-jpa

• InfluxDB

  Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.

  

• JDBI

  27 1,899 9.5 Java

  The Jdbi library provides convenient, idiomatic access to relational databases in Java and other JVM technologies such as Kotlin, Clojure or Scala.

  

Another option is JDBI, that helps you with mappings too while having less features than JPA: https://jdbi.org/
