场景：项目整合mybatis-Plus分页失效，current一直是1，size一直是10，total属性一直是0，数据分页不准
先看官网给的示例：
解决方案是新建mybatis-Plus的配置文件：
package com.amc.config;
import com.baomidou.mybatisplus.annotation.DbType;
import com.baomidou.mybatisplus.autoconfigure.ConfigurationCustomizer;
import com.baomidou.mybatisplus.extension.plugins.MybatisPlusInterceptor;
import com.baomidou.mybatisplus.extension.plugins.inner.OptimisticLockerInnerInterceptor;
import com.baomidou.mybatisplus.extension.plugins.inner.PaginationInnerInterceptor;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.transaction.annotation.EnableTransactionManagement;
/**

* @CreateTime: 2022-12-11 17:36
* @Description: mybatisPlus配置

* @Version: 1.0
*/
@EnableTransactionManagement
@MapperScan("com.amc.**.mapper")
@Configuration
public class MyBatisPlusConfig {
@Bean
public MybatisPlusInterceptor mybatisPlusInterceptor() {
MybatisPlusInterceptor interceptor = new MybatisPlusInterceptor();
PaginationInnerInterceptor innerInterceptor = new PaginationInnerInterceptor();
innerInterceptor.setDbType(DbType.MYSQL);
innerInterceptor.setOverflow(true);
interceptor.addInnerInterceptor(new OptimisticLockerInnerInterceptor());
interceptor.addInnerInterceptor(innerInterceptor);
return interceptor;
}
@Bean
public ConfigurationCustomizer configurationCustomizer() {
return mybatisConfiguration -> mybatisConfiguration.setUseGeneratedShortKey(false);
}
}响应：
{
"code": "00",
"msg": "成功",
"data": {
"records": [

"userId": "1599928568143081472",

}
],
"total": 1,
"size": 1,
"current": 1,
"orders": [],
"optimizeCountSql": true,
"hitCount": false,
"countId": null,
"maxLimit": null,
"searchCount": true,
"pages": 1
}
}
至此，分页方案解决完毕！！！
