mybatis持久化操作“无效的类型111解决”

mybatis持久化操作时，如果插入数据为null的情况下，由于内部机制问题，会导致报错，导致出现：“无效的类型：1111”示例如下：

org.springframework.jdbc.UncategorizedSQLException: Error setting null parameter.  Most JDBC drivers require that the JdbcType must be specified for all nullable parameters. Cause: java.sql.SQLException: 无效的列类型: 1111

; uncategorized SQLException for SQL []; SQL state [99999]; error code [17004]; 无效的列类型: 1111; nested exception is java.sql.SQLException: 无效的列类型: 1111

解决方案：数据库插入、更新操作需要对where后条件做处理具体处理示例如下：

<insert id="insert" parameterType="daSysYgtbl">

		insert into

		DA_SYS_YGTBL(

				ygId,

				ygName,

				ygDm,

				sortId,

				passWord,

				PHONE,

				TEL,

				loginXz,

				ipMac,

				STATUS

			)VALUES (

				#{ygId,jdbcType=NUMBER},

				#{ygName,jdbcType=VARCHAR},

				#{ygDm,jdbcType=VARCHAR},

				#{sortId,jdbcType=VARCHAR},

				#{passWord,jdbcType=VARCHAR},

				#{phone,jdbcType=VARCHAR},

				#{tel,jdbcType=VARCHAR},

				#{loginXz,jdbcType=VARCHAR},

				#{ipMac,jdbcType=VARCHAR},

				#{status,jdbcType=VARCHAR}

			)

	</insert>





<update id="update" parameterType="daSysYgtbl">

		UPDATE DA_SYS_YGTBL

		<set>

			<if test="ygId!=null and ygId!=''">

				ygId = #{ygId,jdbcType=NUMBER},

			</if>

			<if test="ygName!=null and ygName!=''">

				ygName = #{ygName,jdbcType=VARCHAR},

			</if>

			<if test="ygDm!=null and ygDm!=''">

				ygDm = #{ygDm,jdbcType=VARCHAR},

			</if>

			<if test="sortId!=null and sortId!=''">

				sortId = #{sortId,jdbcType=VARCHAR},

			</if>

			<if test="passWord!=null and passWord!=''">

				passWord = #{passWord,jdbcType=VARCHAR},

			</if>

			<if test="phone!=null and phone!=''">

				PHONE = #{phone,jdbcType=VARCHAR},

			</if>

			<if test="tel!=null and tel!=''">

				TEL = #{tel,jdbcType=VARCHAR},

			</if>

			<if test="loginXz!=null and loginXz!=''">

				loginXz = #{loginXz,jdbcType=VARCHAR},

			</if>

			<if test="ipMac!=null and ipMac!=''">

				ipMac = #{ipMac,jdbcType=VARCHAR},

			</if>

			<if test="status!=null and status!=''">

				STATUS = #{status,jdbcType=VARCHAR}

			</if>

		</set>

		WHERE ygId = #{ygId} 

	</update>
