java.sql.SQLSyntaxErrorException: Unknown column 'department_name' in 'field list',設置mybatis.configuration.map-underscore-to-camel-case: true之后沒有效果

報錯信息：

### Error updating database. Cause: java.sql.SQLSyntaxErrorException: Unknown column 'department_name' in 'field list'
### The error may exist in com/jjit/springboot/mapper/DepartmentMapper.java (best guess)
### The error may involve com.jjit.springboot.mapper.DepartmentMapper.insertDept-Inline
### The error occurred while setting parameters
### SQL: insert into department(id,department_name) values(?,?)
### Cause: java.sql.SQLSyntaxErrorException: Unknown column 'department_name' in 'field list'
; bad SQL grammar []; nested exception is java.sql.SQLSyntaxErrorException: Unknown column 'department_name' in 'field list'] with root cause

在application.yml文件配置mybatis.configuration.map-underscore-to-camel-case: true無效，不起作用

解決方法（創建MybatisConfig類）內容如下：

package com.jjit.springboot.config;

import org.apache.ibatis.session.Configuration;
import org.mybatis.spring.boot.autoconfigure.ConfigurationCustomizer;
import org.springframework.context.annotation.Bean;

@org.springframework.context.annotation.Configuration
public class MybatisConfig {
    @Bean
    public ConfigurationCustomizer configurationCustomizer() {
        return new ConfigurationCustomizer() {
            @Override
            public void customize(Configuration configuration) {
                configuration.setMapUnderscoreToCamelCase(true);
            }
        };
    }
}

重啟項目后測試可用。
