Before report a bug, make sure you have: - Searched open and closed [GitHub issues](https://github.com/apache/incubator-shardingsphere/issues). - Read documentation: [ShardingSphere Doc](https://shardingsphere.apache.org/document/current/en/overview). Please pay attention on issues you submitted, because we maybe need more details. If no response **more than 7 days** and we cannot reproduce it on current information, we will **close it**. Please answer these questions before submitting your issue. Thanks! ### Which version of ShardingSphere did you use? 4.0.0-RC2-SNAPSHOT(clone from dev branch) ### Which project did you use? Sharding-JDBC or Sharding-Proxy? Sharding-JDBC ### Expected behavior sql execute success ### Actual behavior Caused by: java.lang.ClassCastException: java.lang.Long cannot be cast to java.lang.Integer ### Reason analyze (If you can) my code below: public List<User> findUsersByPageIntType(Integer begin, Integer end){ String sql = "select id,name,age,email from user limit ?,? "; Object[] params = new Object[] {begin, end}; List<User> userList = jdbcTemplate.query(sql, params, getUserMapper()); return userList; } public List<User> findUsersByPageLongType(Long begin, Long end){ String sql = "select id,name,age,email from user limit ?,? "; Object[] params = new Object[] {begin, end}; List<User> userList = jdbcTemplate.query(sql, params, getUserMapper()); return userList; } first, call findUsersByPageIntType method, it's ok but call findUsersByPageLongType method there was an error -> Caused by: java.lang.ClassCastException: java.lang.Long cannot be cast to java.lang.Integer ### Steps to reproduce the behavior, such as: SQL to execute, sharding rule configuration, when exception occur etc. 1.application.properties spring.shardingsphere.datasource.names=ds0 spring.shardingsphere.datasource.ds0.type=com.zaxxer.hikari.HikariDataSource spring.shardingsphere.datasource.ds0.driver-class-name=com.mysql.jdbc.Driver spring.shardingsphere.datasource.ds0.jdbc-url=jdbc:mysql://127.0.0.1:3306/ttx_util?useUnicode=true&useSSL=false&characterEncoding=utf8 spring.shardingsphere.datasource.ds0.username=test spring.shardingsphere.datasource.ds0.password=test spring.shardingsphere.sharding.tables.user.actual-data-nodes=ds0.user_$->{0..1} spring.shardingsphere.sharding.tables.user.table-strategy.inline.sharding-column=erp_id spring.shardingsphere.sharding.tables.user.table-strategy.inline.algorithm-expression=user_$->{erp_id % 2} spring.shardingsphere.sharding.tables.user.key-generator.column=id spring.shardingsphere.sharding.tables.user.key-generator.type=SNOWFLAKE #是否开启SQL显示，默认值: false spring.shardingsphere.props.sql.show=true 2.table create sql: CREATE TABLE `user_0` ( `id` bigint(20) NOT NULL COMMENT '主键ID', `erp_id` int(11) NOT NULL COMMENT '分表erpId', `name` varchar(30) DEFAULT NULL COMMENT '姓名', `age` int(11) DEFAULT NULL COMMENT '年龄', `email` varchar(50) DEFAULT NULL COMMENT '邮箱', PRIMARY KEY (`id`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4; CREATE TABLE `user_1` ( `id` bigint(20) NOT NULL COMMENT '主键ID', `erp_id` int(11) NOT NULL COMMENT '分表erpId', `name` varchar(30) DEFAULT NULL COMMENT '姓名', `age` int(11) DEFAULT NULL COMMENT '年龄', `email` varchar(50) DEFAULT NULL COMMENT '邮箱', PRIMARY KEY (`id`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4; ### Example codes for reproduce this issue (such as a github link).
