场景

SaaS平台项目，需要根据租户分库，使用ShardingSphere-proxy 版本5.1
项目采用Spring Cloud微服务架构，全部是Spring Boot项目，持久层使用hibernate，版本 5.4
编程语言Java，程序运行，使用jdk 11
数据库PostgresQL 13.5
普通的JPA保存方法，代码没有变动，原本可以正常运行没有报错，使用sharding分库分表后，报错

报错一：分库的表

报错代码

报错的表，是需要分库的表，已经在配置文件里设置好了分库规则和主键规则
使用的就是hibernate普通的保存方法

Long id = this.saveEntity(cmsContentEO);

程序报错

下面是我的应用程序运行报错的部分日志

解决

关键报错是ERROR: relation "hibernate_sequence" does not exist，说明程序没有使用我的主键策略
检查了下主键注解，实体类的底层抽象类，主键策略配置的事AUTO
将主键注解改为 IDENTIFIFY 后解决，不报这个错误了
对于一个项目，建议将公共字段作为抽象类或接口，保持统一性，主键全部使用ID字段，这样也方便以后的修改，像这次，只需要修改抽象类即可，不需要改动所有实体类

	/**
	 * 主键
	 */
	@Id
	@GeneratedValue(strategy = GenerationType.IDENTITY)
	@Column(name = "id")
	private Long id;

报错二：不分库的表

报错代码

部分表不需要分库分表，单独在一个库里存储
已经在sharding的配置文件，设置了公共的主键生成策略
考虑到这些表不需要分库分表，就没有在sharding配置文件里对这些表配置
还是普通的hibernate的保存方法

this.saveEntity(customerInfoEO);

程序报错

insert的是测试数据，没有实际意义
会对部分字段（身份证、手机号）进行加密，使用的也是sharding，这里没有配置，没体现出来

解决

主要报错是ERROR: null value in column "id" of relation "customer_info" violates not-null constraint，就是因为没有自动生成主键导致插入报错
我尝试了5.0 和 5.1 两个版本，都不行，于是用我下载的源码本地调试
一开始是使用我的应用程序，去调取sharding进行调试，后面感觉这样好麻烦，有点傻
因为sharding本身就是伪装成一个数据库连接，我使用Navicat对我的sharding建立数据库连接，直接在里面执行插入SQL，效果和程序一样
进行了源码调试，发现在配置文件里配置了的表，默认的主键策略都会生效，没有在配置文件里出现的表，都没有生效 isGenerate fasle
我尝试把不分库的表也配置进去，发现可以了
以前一直以为，不分库的表，不在配置文件里，默认主键策略也会生效的，因为实际上sharding也读取到了这些表的信息。不知道是不是我的配置有问题，现在没在配置文件里的表，主键策略就是没生效
这样我需要把我的所有表，无论是否需要分库，全部配置到配置文件里，果然都可以了
下面是部分配置
