Maven Central

数据库分批读写交互模板

功能

  • 封装数据分批流式读写模板
  • 封装mysql, es和mongo数据库的读写模板

模块

  • db-exchange-core:核心读写交互模板
  • db-exchange-mysql:封装mysql数据库读写
  • db-exchange-es:封装es数据库读写
  • db-exchange-mongo:封装mongo数据库读写
  • db-exchange-spring-jdbc:封装Spring JDBC读写

快速开始

  1. 添加db-exchange-mysql Maven引用

            <dependency>
                <groupId>com.github.mengzuozhu</groupId>
                <artifactId>db-exchange-mysql</artifactId>
                <version>1.0.1</version>
            </dependency>
  2. mysql读取示例

    public class ExchangeDemo {
    
        public static void main(String[] args) {
            String url = "jdbc:mysql://localhost:3306/test?characterEncoding=utf8&serverTimezone=Asia/Shanghai";
            DataSource dataSource = MysqlUtil.getDataSource(url, "root", "your mysql password");
            MysqlQuery query = MysqlQuery.builder()
                    .dataSource(dataSource)
                    .sql("SELECT * FROM user")
                    .batchSize(100)
                    .build();
            DataReader<Map<String, Object>> mysqlDataReader = new MysqlDataReader<>(query, new ResultSetToMap());
            ListDataCollector<Map<String, Object>> listDataCollector = new ListDataCollector<>();
            ExchangeTemplate.from(mysqlDataReader)
                    .execute(listDataCollector)
                    .await();
            // do something
            List<Map<String, Object>> result = listDataCollector.getResult();
        }
    }
