After that I am not able to reach the services anymore by using the same urls that I was using with the web.xml approach. I don't understand how the ResourceConfig is affecting the paths.

I did the same. Still, I'm unable to invoke it. 回答1: I've read there is no need to mention the servlet in web.xml. You're probably confusing with the legacy Tomcat-builtin InvokerServlet which was present in older versions of Apache Tomcat (and still mentioned in poor and outdated tutorials/books). It indeed allowed to

1. Spring Spring框架是一个轻量级的解决方案，是一个潜在的一站式商店，用于构建企业就绪的应用程序。 Spring框架是一个Java平台，为开发Java应用程序提供全面的基础架构支持。Spring处理基础结构，因此您可以专注于应用程序。Spring使您能够从“普通的Java对象”（POJO）构建应用程序，并将企业服务非侵入性地应用于POJO。此功能适用于Java SE编程模型以及全部和部分Java EE 。但是，Spring是模块化的，允许您仅使用所需的那些部分，而不必引入其余部分。您可以将IoC容器与顶部的任何Web框架一起使用，但也可以仅使用 Hibernate集成代码或JDBC抽象层。Spring框架支持声明式事务管理，通过RMI或Web服务对逻辑的远程访问以及用于持久化数据的各种选项。它提供了功能全面的MVC框架，并使您能够将AOP透明地集成到软件中。 Spring被设计为非侵入式的，这意味着您的域逻辑代码通常不依赖于框架本身。在您的集成层（例如数据访问层）中，将存在对数据访问技术和Spring库的某些依赖关系。但是，将这些依赖项与其余代码库隔离起来应该很容易。Spring的两大核心特征：IoC（控制反转），AOP（面向切面编程）。IoC作用：把对象的控制权交给容器管理。AOP作用：面向切面编程（比如日志打印），底层使用动态代理实现。

1. MyBatis 说出你所了解的持久层（ORM）框架 mybatis，hibernate，jpa，jooq object relationship mapping 建立java 对象与关系型数据库之间的映射关系 mybatis 是轻量级的 orm，hibernate 是重量级的（用注解方式建立orm关系，很多sql由框架生成） jpa 是一套接口，hibernate 同时也作为 jpa 2）什么是 MVC，你的项目中哪里体现了 MVC 模型（model） - 数据，domain，java bean 视图（view） - 数据的展现方式，jsp 控制器（controller） - 把模型和视图联系在一起，对应着 servlet 3）梳理一下 MyBatis 的使用步骤 pom.xml 中添加 mybatis 依赖 resources/mybatis-config.xml 配置文件(配置数据库连接和映射关系) 提供 xml mapper 或 接口 映射 (都是通过这些映射管理 sql 语句) 使用 mybatis 的api 执行增删改查 4）列举 MyBatis 中重要的接口，它们分别是干什么的？ SqlSessionFactory (接口) - 创建 sqlsession 的 SqlSessionFactoryBuilder (类) - 创建工厂对象 SqlSession (接口
