开发工具使用的idea2022.3，数据库是mysql5.X系列，springboot用的是2.7系列，使用了java8的joda类型的时间格式完成mybatis的插入操作。下面贴代码说明实现过程
项目结构如下图：
下面说一些关键的maven配置
<!-- springboot mybatis支持包 -->
<dependency>
<groupId>org.mybatis.spring.boot</groupId>
<artifactId>mybatis-spring-boot-starter</artifactId>
<version>2.2.2</version>
</dependency>
<!--支持对joda的支持-->
<dependency>
<groupId>io.eliez</groupId>
<artifactId>joda-time-mybatis</artifactId>
<version>2.0.2</version>
</dependency>
vacationMapper类的写法：
@Mapper
public interface VacationMapper {
void addVactionApplyInfo(VacationApply vacationApply);
}
VacationApply写法
import com.fasterxml.jackson.annotation.JsonFormat;
import lombok.Getter;
import lombok.Setter;
import lombok.ToString;
import org.joda.time.DateTime;
import java.util.Date;
@Getter
@Setter
@ToString
public class VacationApply {
//请假开始时间、结束时间、请假时长、申请人、对应实例ID、请假类型、
private int vaID;
private DateTime bTime;
private DateTime eTime;
private double len;//请假时长，转换成分钟数
private String applicant;//请假申请人
private String instanceID;//实例ID
private String type;//请假类型
private String desc;//请假原因
}
vacationMapper.xml的写法
<?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.imooc.activity_workflow.mapper.VacationMapper">
<insert id="addVactionApplyInfo" parameterType="com.imooc.activity_workflow.model.VacationApply">
insert into vacationapply(`bTime`,`eTime`,`len`,`applicant`,`instanceID`,`type`,`desc`) VALUES (#{bTime,typeHandler=org.joda.time.mybatis.handlers.DateTimeTypeHandler},
#{eTime,typeHandler=org.joda.time.mybatis.handlers.DateTimeTypeHandler},
#{len},#{applicant},#{instanceID},#{type},#{desc})
</insert>
</mapper>
这里注意joda格式的字段需要指定类型转换就行了。
打印的结果
JDBC Connection [com.alibaba.druid.proxy.jdbc.ConnectionProxyImpl@4942e6af] will be managed by Spring
==> Preparing: insert into vacationapply(`bTime`,`eTime`,`len`,`applicant`,`instanceID`,`type`,`desc`) VALUES (?, ?, ?,?,?,?,?)
