Mybatis新增之後返回一個id有兩種方法，如下：

A.直接寫在insert標籤裡

<insert id="insertRadar" parameterType="com.hhigh.business.domain.Radar" useGeneratedKeys="true" keyProperty="id">
	insert into t_radar (
		<include refid="radarAttributes" />
	) values (
		#{id},#{file_name},#{format},#{file_size},#{file_url},#{station_name},#{province},#{city},
		#{cnty},#{town},#{datetime},#{station_id_c},#{year},#{mon},#{day},#{hour},#{min},#{second},
		#{rada_model},#{scanning_mode},#{filename_orig}
	)
</insert>
 

B.寫在插入語句下面

<insert id="insertRadar" parameterType="com.hhigh.business.domain.Radar">
	insert into t_radar (
		<include refid="radarAttributes" />
 	) values (
		#{id},#{file_name},#{format},#{file_size},#{file_url},#{station_name},#{province},#{city},
		#{cnty},#{town},#{datetime},#{station_id_c},#{year},#{mon},#{day},#{hour},#{min},#{second},
		#{rada_model},#{scanning_mode},#{filename_orig}
	)
	<selectKey resultType="java.lang.Integer" keyProperty="id" order="AFTER" >
		select @@identity as id;
	</selectKey>
</insert>
