SpringBoot整合Mybatis-Plus分页失效

news2024/10/7 17:29:17

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;

 * @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);
    }
}
