1.新建一个maven项目
2.在pom.xml中，配置所需的jar包及其版本号

3.建造完成后，自动生成一个web.xml
在web.xml中:
A. 加载Spring配置文件
B. 配置Spring的监听
C. 配置SpringMVC的核心控制器
D. 配置编码过滤器,作用:防止中文乱码
E. 配置验证码相关servlet（有需要的话）
代码如下：
<!-- 加载Spring配置文件 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicationContext.xml</param-value> </context-param> <!--配置Spring的监听--> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- 配置SpringMVC的核心控制器 拦截所有请求 --> <servlet> <servlet-name>springMVC</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:springMVC.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>springMVC</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> <!-- 配置编码过滤器,作用:防止中文乱码 --> <filter> <filter-name>abc</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <async-supported>true</async-supported> <init-param> <param-name>encoding</param-name> <param-value>utf-8</param-value> </init-param> </filter> <filter-mapping> <filter-name>abc</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- 配置验证码相关servlet --> <servlet> <servlet-name>CheckCodeServlet</servlet-name> <servlet-class>cn.fh.servlet.CheckCodeServlet</servlet-class> </servlet> <servlet-mapping> <servlet-name>CheckCodeServlet</servlet-name> <url-pattern>/CheckCodeServlet</url-pattern> </servlet-mapping>
4.在resources文件夹下，创建并配置applicationContext.xml和springMVC.xml文件
applicationContext.xml中详细配置：
A. 创建数据源：创建c3p0连接池，连接数据库
B. 根据数据源，创建实体管理工厂
C. 配置事务
D. SpringDataJpa的相关配置
E. 开启组件的扫描
F. 定义advice,配置传播特性、事务隔离级别、只读事务、回滚策略
G. 切点配置 execution
springMVC.xml
A. 开启注解
B. 放开静态资源
C. 配置视图解析器
D. 上传文件相关配置
E. 注册拦截器
5.新建model层，在实体类中，通过注解的方式来配置数据库中表的信息
@Entity 表明这是一个实体类
@Table(name = "")在数据库中生成对应的表名
@Id声明主键
@GeneratedValue设置主键生成策略
GenerationType.IDENTITY mySql主键生成策略
GenerationType.SEQUENCE oracle主键生成策略
GenerationType.AUTO 根据不同的数据库，设置对应的主键生成策略
6.新建repository层，并创建接口，同时继承两个接口
其中：
分别是: JpaRepository<T,ID>和JpaSpecificationExecutor<T>
T 与model层对象相对应
ID跟model层对象Id的类型相对应
JpaRepository:排序，分页，一些简单的增删改查
JpaSpecificationExecutor:复杂的动态条件查询
7.新建service serviceImpl controller层，并完成自动注入(通过@Autowired注解)
其中：
serviceImpl类中注入repository
@Autowired private UserRepository userRepository;
controller层中注入service
@Autowired private UserService userService;
8.新建controller层之后，先测试一下项目的视图解析器(@RequestMapping) 和springMVC拦截器（主要通过@ResponseBody注解，把返回的结果转换为json格式，给浏览器），然后再进行后续代码的具体编写。
// 测试拦截器
@RequestMapping("test")
@ResponseBody
public String test(){
return "test";
}
// 测试SpringMVC视图解析器
@RequestMapping("toIndex")
public String toIndex(){
return "index";
}
9.将项目部署到tomcat下，并运行此项目。
