day01（RESTful Web Service、SVN）

1. 今日大纲

1. 搭建SSM环境
2. 基于SSM环境实现用户管理系统
3. 学习RESTful Web Service
4. 学习SVN

 

1. 统一开发环境

1. JDK
   1.7 32？ 64？ -- 64
2. Eclipse

   使用4.4.1 luna 课前资料中提供
   

3. 数据库，mysql 《淘宝技术这十年》
   1. 统一使用5.6，但是，项目开发阶段可以使用5.5或5.6
   2. Mysql的读写分离，统一成5.6
4. 数据库的客户端工具
   1. 
   2. Mysql最好用的客户端。
   3. 
5. Maven
   1. 统一使用3.2.3
   2. 统一使用Maven的私服
      http://192.168.50.22:8081/nexus/#welcome
      
6. 实施：《Eclipse相关配置.docx》

   1. 实施

      1. Eclipse

 

1. 搭建SSM环境

   1. 数据库

      1. 使用navicat创建数据库连接

执行SQL脚本：

 

 

1. Tb_user

查看表结构：

 

表结构：

1. 统一管理依赖的版本

需要：将多个项目的依赖的版本号统一管理起来。

 

如何实现？ --- 使用Maven的继承实现。

1. 导入itcast-parent

 

1. 完整pom

1. 继承parent

1. 出现小红叉

 

解决：

 

 

原因：

 

定义的java编译器插件的jdk版本和默认使用的jdk版本不一致，导致。

 

 

1. 创建工程

   1. 新建工程

1. 填写项目的Maven坐标

 

 

Maven会自动从192.168.50.22的私服下载所需要的依赖。

1. 子工程使用依赖

 

1. Parent中的依赖管理

 

1. 导入依赖

1. SpringMVC配置文件

1. Mybatis和Spring的整合

   1. 整合文件

1. Mybatis的全局配置文件

 

1. 导入jsp页面

 

1. 启动报错

由于在mappers目录中没有xml配置文件，所以报错。

 

1. 通用页面跳转

 

测试：

1. 配置通用Mapper

   1. 导入依赖

已完成。

1. 配置通用Mapper的插件

1. 作业

分页助手和通用Mapper的配置的顺序是否能颠倒？

1. User实体添加JPA注解

1. 创建UserMapper接口

 

1. EasyUI的datagrid的数据结构

 

1. 封装EasyUIResult

 

1. 实现用户列表的查询

   1. Controller实现

1. 分页（分页助手）

   1. 导入依赖

已完成。

1. 配置插件

1. 使用分页助手

1. UserService

使用分页助手完成分页功能。

1. UserMapper

 

1. 效果

1. Datagrid的formatter方法

后台返回的数据是时间戳：

 

 

 

1. 扩展JS的内置对象的方法

在内置对象的原型上扩展方法：

1. RESTful Web Service

   1. 大纲

1. REST是什么？

大神：

 

论文：Roy Thomas Fielding博士论文REST(中文版).pdf

1. REST到底是什么？

1. RESTful是什么？

 

Web service：

JAX-WS

JAX-RS

 

 

1. REST 架构的主要原则

1. URI和URL

1. 无状态性

1. 资源操作

 

 

之前的操作：

http://127.0.0.1/user/query/1 GET 根据用户id查询用户数据

http://127.0.0.1/user/save POST 新增用户

http://127.0.0.1/user/update POST 修改用户信息

http://127.0.0.1/user/delete GET/POST 删除用户信息

 

RESTful用法：

http://127.0.0.1/user/1 GET 根据用户id查询用户数据

http://127.0.0.1/user POST 新增用户

http://127.0.0.1/user PUT 修改用户信息

http://127.0.0.1/user DELETE 删除用户信息

1. REST接口定义

1. 最佳实践

   1. REST接口设计

1. 响应设计

 

1. 响应示例

 

1. 指定响应的属性字段

1. http响应状态码

1. SpringMVC实现RESTful服务

1. 查询资源

1. 新增资源

 

测试：

 

 

1. 更新资源

 

Service：

 

测试：

 

默认情况下，PUT请求是无法提交表单数据的，需要在web.xml中添加过滤器解决：

 

    <!-- 解决PUT请求无法提交表单数据的问题 -->

    <filter>

        <filter-name>HttpMethodFilter</filter-name>

        <filter-class>org.springframework.web.filter.HttpPutFormContentFilter</filter-class>

    </filter>

    <filter-mapping>

        <filter-name>HttpMethodFilter</filter-name>

        <url-pattern>/*</url-pattern>

    </filter-mapping>

 

1. 删除资源

 

测试：

 

 

需要在web.xml中添加过滤器解决DELETE请求无法提交表单数据的问题：

    <!--

        将POST请求转化为DELETE或者是PUT

        要用_method指定真正的请求参数

     -->

    <filter>

        <filter-name>HiddenHttpMethodFilter</filter-name>

        <filter-class>org.springframework.web.filter.HiddenHttpMethodFilter</filter-class>

    </filter>

    <filter-mapping>

        <filter-name>HiddenHttpMethodFilter</filter-name>

        <url-pattern>/*</url-pattern>

    </filter-mapping>
