异常：java.sql.SQLException: 无效的列类型: 1111

异常现象

最近项目中遇到的，项目框架用的SpringBoot，MyBatis做持久层，以下是出现的异常重现：

异常分析

根据异常信息：nested exception is org.apache.ibatis.type.TypeException: Could not set parameters for mapping: ParameterMapping{property='phone', mode=IN, javaType=class java.lang.Object, jdbcType=null, numericScale=null, resultMapId='null', jdbcTypeName='null', expression='null'}. Cause: org.apache.ibatis.type.TypeException: Error setting null for parameter #1 with JdbcType OTHER . Try setting a different JdbcType for this parameter or a different jdbcTypeForNull configuration property. Cause: java.sql.SQLException: 无效的列类型: 1111] with root cause，大概可以确定出问题的是传入的参数为null，正常情况下MyBatis是可以把null和空字符串保存到数据库的，这里不应该报错；再看对应的mapper如下：

int update1(@Param(value = "id") String id, @Param(value = "phone") String phone);

xml配置如下：

		update TEST_USER set phone = #{phone}
		where id = #{id}
	

原来，xml配置中对应的开发忘了指定参数的类型：jdbcType。在没有指定的情况下，MyBatis会把对应参数的jdbcType设置为：

JdbcType.OTHER。

 

解决办法

把对应的xml中的参数加上对应的jdbcType：

		update TEST_USER set phone = #{phone,jdbcType=VARCHAR}
		where id = #{id,jdbcType=VARCHAR}
