[Solved] org.apache.ibatis.binding.BindingException: Parameter ‘area_id’ not found. Available parameters are [areaId, param1]


1. Error information:

API Documentation:

org.apache.ibatis.binding.BindingException: Parameter ‘area_ id’ not found. Available parameters are [areaId, param1]

org.apache.ibatis.binding.BindingException: Parameter ‘area_ id’ not found。 The available parameters are [areaid, Param1]

2. Error reporting reason:

The XML internal input parameter has no corresponding.

3. Solution:

area_id = #{areaId,jdbcType=VARCHAR}; Front area_ID is the same as the header in the database, and the simultaneous interpreting of the same areaId is the same as the @Param.

Mapper layer:

public interface SalaryStandardConfigMapper extends BaseMapper<SalaryStandardConfig> {

    SalaryStandardConfig getConfigIdByAreaId(@Param("areaId") String areaId);

    Integer getConfigIdNums(@Param("areaId") String areaId);

XML layer:

    <select id="getConfigIdNums" resultType="java.lang.Integer" parameterType="java.lang.String">
        COUNT(config_id), area_id
        area_id = #{areaId,jdbcType=VARCHAR};
