工具类，它包含一些实用方法，可使从 classpath 或其他位置加载资源文件更加容易。 String resource = "org/mybatis/example/mybatis-config.xml"; InputStream inputStream = Resources.getResourceAsStream(resource); sqlSessionFactory = new SqlSessionFactoryBuilder() value="${password}"/> resource="org/mybatis/example/BlogMapper.xml"/> 当然，还有很多可以在XML 文件中进行配置，上面的示例指出的则是最关键的部分。要注意 properties 这些属性都是可外部配置且可动态替换的，既可以在典型的 Java 属性文件中配置，亦可通过 properties 元素的子元素来传递。例 如： resource="org/mybatis/example/config.properties">

ShardingSphere ElasticJob document Through the functions of flexible scheduling, resource management and job management, it creates a distributed scheduling solution suitable for Internet scenarios, and can release operators too, so that they do not have to worry about jobs high availability and management, and can automatic operation by simply adding servers. ElasticJob is a lightweight, decentralized improvement – Job processing capacity is flexible and scalable with the allocation of resources • Resource Assign – Execute job on suitable time and assigned resources – Aggregation same job to same job
