1、查看项目是否引入自动配置的数据源(比如druid-spring-boot-starter),如果有,先删除,sharding启动时会自动创建数据源,两者冲突。如果还是想用druid链接池。引入:

 

<dependency>
     <groupId>com.alibaba</groupId>
      <artifactId>druid</artifactId>
      <version>1.1.22</version>
 </dependency>

 或者在启动类上,排出

DruidDataSourceAutoConfigure,
后者在java类中配置一个sharding-DataSource,加上@Primary注解,反正就是别让他自己创建就行,

2、报错:

Caused by: java.sql.SQLFeatureNotSupportedException: getCatalog
	at org.apache.shardingsphere.shardingjdbc.jdbc.unsupported.AbstractUnsupportedOperationConnection.getCatalog(AbstractUnsupportedOperationConnection.java:91)
	at org.apache.shardingsphere.shardingjdbc.jdbc.core.datasource.EncryptDataSource.isTableExist(EncryptDataSource.java:88)

 

查看是否使用了flywaydb,如果有,删除掉,这个github上有人提了issues,可还是没有解决,参考这个,https://github.com/apache/shardingsphere/issues/2488

3、使用JPA-Hibernate的时候,id不要用数据库自增的方式,可以使用hutool工具包提供的Idutil生成器

由于需要主从同步,分库就没做,这里贴一下分表的配置

spring.shardingsphere.datasource.names=framework

spring.shardingsphere.datasource.framework.type=com.alibaba.druid.pool.DruidDataSource
spring.shardingsphere.datasource.framework.driver-class-name=com.mysql.jdbc.Driver
spring.shardingsphere.datasource.framework.url=
spring.shardingsphere.datasource.framework.username=
spring.shardingsphere.datasource.framework.password=

#article
spring.shardingsphere.sharding.tables.article.actual-data-nodes=framework.article$->{0..4}
spring.shardingsphere.sharding.tables.article.table-strategy.inline.sharding-column=id
spring.shardingsphere.sharding.tables.article.table-strategy.inline.algorithm-expression=article$->{id % 5}

spring.shardingsphere.sharding.tables.article_item.actual-data-nodes=framework.article$->{0..4}
spring.shardingsphere.sharding.tables.article_item.table-strategy.inline.sharding-column=id

spring.shardingsphere.sharding.tables.articles_attribute.actual-data-nodes=framework.articles_attribute$->{0..4}

spring.shardingsphere.sharding.tables.articles_attribute.table-strategy.inline.algorithm-expression=articles_attribute$->{id % 5}

spring.shardingsphere.sharding.tables.articles_attribute_item.actual-data-nodes=framework.articles_attribute$->{0..4}
spring.shardingsphere.sharding.tables.articles_attribute_item.table-strategy.inline.sharding-column=id
spring.shardingsphere.sharding.tables.articles_attribute_item.table-strategy.inline.algorithm-expression=articles_attribute$->{id % 5}


spring.shardingsphere.props.sql.show=true
