Usage-Guide

easy-query 🚀 is a high-performance, lightweight, and versatile Java/Kotlin object query ORM framework that supports database sharding and read-write separation.

Overview

easy-query is a dependency-free JAVA/Kotlin ORM framework, extremely lightweight, with high performance. It supports single table queries, multi-table queries, union, subqueries, pagination, dynamic table names, VO object query returns, logical deletion, global interception, database column encryption (supporting high-performance LIKE queries), data tracking for differential updates, optimistic locking, multi-tenancy, automatic database sharding, automatic table sharding, read-write separation, and supports full-featured external extension customization of the framework, with strong-typed expressions.

Sharding

easy-query支持Table Sharding、Database Sharding、Table Sharding+Database Sharding

Table-Sharding

//创建Sharding对象
@Data
@Table(value = "t_topic_sharding_time",shardingInitializer = TopicShardingTimeShardingInitializer.class)
@ToString
public class TopicShardingTime {

    @Column(primaryKey = true)
    private String id;
    private Integer stars;
    private String title;
    @ShardingTableKey
    private LocalDateTime createTime;
}
//Sharding初始化器很简单 假设我们是2020年1月到2023年5月也就是当前时间进行Sharding那么要生成对应的Sharding表每月一张
public class TopicShardingTimeShardingInitializer extends AbstractShardingMonthInitializer<TopicShardingTime> {

    @Override
    protected LocalDateTime getBeginTime() {
        return LocalDateTime.of(2020, 1, 1, 1, 1);
    }

    @Override
    protected LocalDateTime getEndTime() {
        return LocalDateTime.of(2023, 5, 1, 0, 0);
    }


    @Override
    public void configure0(ShardingEntityBuilder<TopicShardingTime> builder) {

////以下条件可以选择配置也可以不配置用于优化Sharding性能
//        builder.paginationReverse(0.5,100)
//                .ascSequenceConfigure(new TableNameStringComparator())
//                .addPropertyDefaultUseDesc(TopicShardingTime::getCreateTime)
//                .defaultAffectedMethod(false, ExecuteMethodEnum.LIST,ExecuteMethodEnum.ANY,ExecuteMethodEnum.COUNT,ExecuteMethodEnum.FIRST)
//                .useMaxShardingQueryLimit(2,ExecuteMethodEnum.LIST,ExecuteMethodEnum.ANY,ExecuteMethodEnum.FIRST);

    }
}
//Sharding时间路由规则按月然后beanSharding属性就是LocalDateTime也可以自定义实现
public class TopicShardingTimeTableRoute extends AbstractMonthTableRoute<TopicShardingTime> {

    @Override
    protected LocalDateTime convertLocalDateTime(Object shardingValue) {
        return (LocalDateTime)shardingValue;
    }
}

数据库脚本参考源码

其中shardingInitializer为Sharding初始化器用来初始化告诉框架有多少Sharding的表名(支持动态添加)

ShardingTableKey表示哪个字段作为Sharding键(Sharding键不等于主键)
