Spring Data JPA column既有下划线，又有驼峰

参考：https://www.jianshu.com/p/fc2c79814956

驼峰与下划线的转化 通用配置：

无修改命名

spring.jpa.hibernate.naming.physical-strategy=org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl

遇到大写加下划线"_" 的命名

spring.jpa.hibernate.naming.physical-strategy=org.springframework.boot.orm.jpa.hibernate.SpringPhysicalNamingStrategy

如果项目中使用的表既有下划线，又有驼峰，而且还不想使用@Column一个个标识：

spring.jpa.hibernate.naming.physical-strategy=org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl 

ReceptionDBConfig.class

// 配置字段
protected Map<String, Object> jpaProperties() {
        Map<String, Object> props = new HashMap<>();
        props.put("hibernate.physical_naming_strategy", SpringPhysicalNamingStrategy.class.getName());
        props.put("hibernate.implicit_naming_strategy", SpringImplicitNamingStrategy.class.getName());
        return props;
    }

@Bean(name = "receptionEntityManagerFactory")
	public LocalContainerEntityManagerFactoryBean kcEntityManagerFactory(EntityManagerFactoryBuilder builder,
			@Qualifier("receptionDataSource") DataSource dataSource) {
		return builder.dataSource(dataSource).packages("com.icil.elsa.milestone.query.entities.reception")
				.persistenceUnit("reception")
				.properties(jpaProperties())  // 引入属性配置
				.build();
	}
