##### 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][http_localhost_oracleMoreInsert]

###### 3.2. 查看数据库 ######

###### 3.3. 配置文件部分 ######
