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

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

解决方法（创建MybatisConfig类）内容如下：

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);
            }
        };
    }
}

重启项目后测试可用。
