SpringBoot+mybatisPlus分页,与字段自动填充配置类

使用分页所需依赖

<dependency>
            <groupId>com.baomidou</groupId>
            <artifactId>mybatis-plus-extension</artifactId>
            <version>3.4.1</version>
        </dependency>

配置详情

import com.baomidou.mybatisplus.annotation.DbType;
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.context.annotation.Primary;
import org.springframework.transaction.annotation.EnableTransactionManagement;

@MapperScan(basePackages = "cn.mbz.carsale.mapper")
@EnableTransactionManagement
@Configuration
public class MybatisPlusConfig {
    @Bean
    @Primary
    public MybatisPlusInterceptor mybatisPlusInterceptor() {
        MybatisPlusInterceptor interceptor = new MybatisPlusInterceptor();
        //分页支持(添加了一个分页插件)
        interceptor.addInnerInterceptor(new PaginationInnerInterceptor(DbType.MYSQL));
        //乐观锁支持的插件
        interceptor.addInnerInterceptor(new OptimisticLockerInnerInterceptor());
        return interceptor;
    }
}

使用自动填充所需依赖

<dependency>
            <groupId>com.baomidou</groupId>
            <artifactId>mybatis-plus-core</artifactId>
            <version>3.4.1</version>
        </dependency>

配置详情

import com.baomidou.mybatisplus.core.handlers.MetaObjectHandler;
import org.apache.ibatis.reflection.MetaObject;
import org.springframework.stereotype.Component;

import java.util.Date;

@Component
public class MyMetaObjectHandler implements MetaObjectHandler {
    @Override
    public void insertFill(MetaObject metaObject) {
        //如果插入数据的时候遇到 createTime 则填充当前时间
        this.setFieldValByName("createTime", new Date(), metaObject);
        //如果插入数据的时候遇到 updateTime 则填充当前时间
        this.setFieldValByName("updateTime", new Date(), metaObject);
        //如果插入数据的时候遇到 deleted 则填充1
        this.setFieldValByName("deleted", 1, metaObject);
        //如果插入数据的时候遇到 status 则填充1
        this.setFieldValByName("status", "1", metaObject);
    }

    @Override
    public void updateFill(MetaObject metaObject) {
        //如果更新数据的时候遇到 updateTime 则填充当前时间
        this.setFieldValByName("updateTime", new Date(), metaObject);
    }
}

例如,如下:实体类配置

/**
     * 逻辑删除
     * 0表示删除 1表示正常
     */
    @TableLogic(value = "1", delval = "0")
    //自动填充
    @TableField(fill = FieldFill.INSERT)
    private Integer deleted;
