一、数据库部分

1. 创建数据库

创建more-insert

2. 初始化表结构

-- 一次性插入多张表测试
--oracle 表结构
create table HERO
(
    SNO       VARCHAR2(20) not null,
    USER_NAME VARCHAR2(20),
    AGE       NUMBER(3)
);

alter table HERO
    add primary key (SNO);

create table HERO2
(
    SNO       VARCHAR2(20) not null,
    USER_NAME VARCHAR2(20),
    AGE       NUMBER(3)
);
alter table HERO2
    add primary key (SNO);

二、代码部分

声明：这里为了演示省略service层

2.1. controller

package com.gblfy.modular.order.controller;

import com.gblfy.modular.order.mapper.MysqlMoreInsertMapper;
import com.gblfy.modular.order.model.request.OracleMoreInsertParam;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class MoreController {

    @Autowired
    private OraclelMoreInsertMapper oraclelMoreInsertMapper;
    
    @GetMapping("/oracleMoreInsert")
    public String oracleMoreInsert() {
        OracleMoreInsertParam oracleMoreInsertParam = new OracleMoreInsertParam();
        oracleMoreInsertParam.setSno("1");
        oracleMoreInsertParam.setUserName("Name1");
        oracleMoreInsertParam.setAge(1);
        oracleMoreInsertParam.setSno2("2");
        oracleMoreInsertParam.setUserName2("Name2");
        oracleMoreInsertParam.setAge2(2);

        oraclelMoreInsertMapper.oraclelmoreInsert(oracleMoreInsertParam);
        return "SUCCESS";
    }
}

2.2. mapper接口

package com.gblfy.modular.order.mapper;

import com.baomidou.dynamic.datasource.annotation.DS;
import com.gblfy.modular.order.model.request.OracleMoreInsertParam;
import org.apache.ibatis.annotations.Param;

/**
 * <p>
 * 通用Mapper 接口
 * </p>
 *
 * @author gblfy
 * @since 2021-08-13
 */
@DS("oracle_1")
public interface OraclelMoreInsertMapper {
    void oraclelmoreInsert(@Param("paramCondition") OracleMoreInsertParam paramCondition);

}

mapper类上添加@DS注解是因为我使用了多数据源，不涉及可以删除此注解

2.3. 映射文件

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.gblfy.modular.order.mapper.OraclelMoreInsertMapper">

    <insert id="oraclelmoreInsert" parameterType="com.gblfy.modular.order.model.request.OracleMoreInsertParam">
        begin
        insert into hero(SNO, USER_NAME, AGE) values (#{paramCondition.sno}, #{paramCondition.userName}, #{paramCondition.age});
        insert into hero2(SNO, USER_NAME, AGE) values (#{paramCondition.sno2}, #{paramCondition.userName2}, #{paramCondition.age2});
        end;
    </insert>

</mapper>

2.4. 参数封装

package com.gblfy.modular.order.model.request;

import lombok.Data;

import java.io.Serializable;

/**
 * oracle演示对象
 *
 * @author gblfy
 * @since 2021-08-13
 */
@Data
public class OracleMoreInsertParam implements Serializable {

    private static final long serialVersionUID = 1L;
    private String sno;
    private String userName;
    private Integer age;
    private String sno2;
    private String userName2;
    private Integer age2;
}

三、测试验证

3.1. 发起请求

​​http://localhost/oracleMoreInsert​​

3.2. 查看数据库

3.3. 配置文件部分

########################################## 多数据源配置 ############################################
spring:
  datasource:
    dynamic:
      primary: master #设置默认的数据源或者数据源组,默认值即为master
      strict: false #严格匹配数据源,默认false. true未匹配到指定数据源时抛异常,false使用默认数据源
      datasource:
        master:
          url: jdbc:mysql://localhost:3306/more-insert?autoReconnect=true&useUnicode=true&characterEncoding=utf8&zeroDateTimeBehavior=CONVERT_TO_NULL&useSSL=false&serverTimezone=CTT&nullCatalogMeansCurrent=true&allowMultiQueries=true
          username: root
          password: 123456
          driver-class-name: com.mysql.cj.jdbc.Driver # 3.2.0开始支持SPI可省略此配置
