hi：
spring的版本为5.0.4-release，在使用shardingsphere-4.0.0-RC2版本的时候，，原有老版本配置（sharding-sphere：3.0.0.M3）的分表策略在该版本下项目启动的时候报错；后来核对了下新老sharding的分表策略，在使用上面做了修改
老版本
<sharding:inline-strategy id="xxx"
sharding-column="asset_acct_id"
algorithm-expression="xxx_${Long.valueOf(asset_acct_id.substring(asset_acct_id.length()
- 4, asset_acct_id.length())) % 10}"/>
新版本
<sharding:inline-strategy id="xxx"
sharding-column="asset_acct_id"
algorithm-expression="xxx_$->{Long.valueOf(asset_acct_id.substring(asset_acct_id.length()
- 4, asset_acct_id.length())) % 10}"/>
修改前报错的信息如下：
2019-10-31 14:19:30,238 ERROR [main] o.s.boot.SpringApplication
