Spring boot+Mybatis 多数据源驼峰式/普通式驼峰式命名

一：普通式驼峰式命名

1、方式一

　　直接application.yml文件中配置开启

#mybatis配置
mybatis:
  typeAliasesPackage: com.example.mybaitsxml.dao.entity
  mapperLocations: classpath:mapper/*.xml
  configuration:
    map-underscore-to-camel-case: true

2、方式二

　application.yml 文件中配置引入mybatis-config.xml。

• application.yml文件：

#mybatis配置
mybatis:
  typeAliasesPackage: com.example.mybaitsxml.dao.entity
  mapperLocations: classpath:mapper/*.xml
  configLocation: classpath:/mybatis-config.xml

• mybatis-config.xml进行配置驼峰命名：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration
        PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-config.dtd">

<configuration>
    <!--开启驼峰命名规则自动转换-->
    <settings>
       <setting name="mapUnderscoreToCamelCase" value="true" />
    </settings>
</configuration>

二：多数据源驼峰式命名

• 多数据源切换实现连接 此链接实现中已配置（https://blog.youkuaiyun.com/Ghost_hell/article/details/109550749）
• 在配置类方法上加入如下即可

    @Bean(name = "test1SqlSessionFactory")
    @Primary
    public SqlSessionFactory sqlSessionFactory(@Qualifier("test1DataSource") DataSource dataSource) throws Exception {
        SqlSessionFactoryBean bean = new SqlSessionFactoryBean();
        org.apache.ibatis.session.Configuration configuration = new org.apache.ibatis.session.Configuration();
        configuration.setMapUnderscoreToCamelCase(true);
        bean.setConfiguration(configuration); #设置驼峰式命名
        bean.setDataSource(dataSource);
        bean.setMapperLocations(new PathMatchingResourcePatternResolver().getResources("classpath*:mapping/test1/*Mapper.xml"));
        return bean.getObject();
    }
