SpringBoot使用MybatisPlus分頁插件

MybatisPlus3.4.1版本

1、配置分頁插件

@Configuration
public class MybatisPlusConfig {

    /*    舊版本配置
    @Bean
    public PaginationInterceptor paginationInterceptor(){
        return new PaginationInterceptor();
    }*/

    /**
     * 新的分頁插件,一緩和二緩遵循mybatis的規則,需要設置
     * MybatisConfiguration#useDeprecatedExecutor = false 避免緩存出現問題
     */
    @Bean
    public MybatisPlusInterceptor mybatisPlusInterceptor() {
        MybatisPlusInterceptor interceptor = new MybatisPlusInterceptor();
        interceptor.addInnerInterceptor(new PaginationInnerInterceptor(DbType.MYSQL));
        return interceptor;
    }

    @Bean
    public ConfigurationCustomizer configurationCustomizer() {
        return configuration -> configuration.setUseDeprecatedExecutor(false);
    }
}

 

2、添加@MapperScan注解，掃描mapper接口

@SpringBootApplication
@MapperScan("com.donleo.mp.mapper")
public class MybatisPlusApplication {

    public static void main(String[] args) {
        SpringApplication.run(MybatisPlusApplication.class, args);
    }

}

 

3、測試

 /**
     * MybatisPlus分頁插件使用
     */
    @Test
    void TestPagination(){
        Page<User> userPage = new Page<User>(1,2);
        Page<User> pageList = userMapper.selectPage(userPage, new QueryWrapper<User>()
                .eq("nick_name", "xx")
        );
        long current = pageList.getCurrent();
        long size = pageList.getSize();
        long total = pageList.getTotal();

        System.out.println("當前頁："+current);
        System.out.println("一頁顯示幾條："+size);
        System.out.println("總條數："+total);
        System.out.println("查詢數據："+pageList.getRecords());
    }

查詢結果：
