一、准备工作

  • 安装并配置Java运行环境
  • Oracle数据库的安装与配置
  • 安装并配置Tomcat
  • 配置Maven环境
  • 创建Maven web-app项目

二、项目结构

在这里插入图片描述

三、导包

因为使用Maven管理项目，所以jar无需手动导入包，只需在pom.xml中配置即可。

pom.xml配置文件如下

  1. <?xml version="1.0" encoding="UTF-8"?>
  2. <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

  147.         </resources>
  148.     </build>
  149. </project>

四、SpringMVC配置

spring-mvc.xml配置文件如下

  1. <?xml version="1.0" encoding="UTF-8"?>
  2. <beans xmlns="http://www.springframework.org/schema/beans"
  3.        xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p"
  4.        xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  5.        xsi:schemaLocation="http://www.springframework.org/schema/beans
  6.       http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
  7.       http://www.springframework.org/schema/context
  8.       http://www.springframework.org/schema/context/spring-context-3.1.xsd
  9.       http://www.springframework.org/schema/mvc
  10.       http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">
  12.     <!-- 注解扫描包，扫描 -->
  13.     <context:component-scan base-package="cn.demo.controller" />
  15.     <!-- 开启mvc注解 -->
  16.     <mvc:annotation-driven/>
  18.     <!--配置视图解析器-->
  19.     <bean id="viewResolver"
  20.           class="org.springframework.web.servlet.view.InternalResourceViewResolver">
  21.         <!--视图名称前缀-->
  22.         <property name="prefix" value="/WEB-INF/jsp/"></property>
  23.         <!--视图名称后缀-->
  24.         <property name="suffix" value=".jsp"></property>
  25.     </bean>
  27.     <!--配置静态资源路径-->
  28.     <mvc:resources mapping="/statics/**" location="/statics/"/>
  29. </beans>

在web.xml中完善springmvc配置

  1. <?xml version="1.0" encoding="UTF-8"?>
  2. <web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee"
  3.          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  4.          xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
  5.     http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">
  7.   <!-- 配置前端控制器DispatcherServlet-->
  8.   <servlet>
  9.     <servlet-name>springmvc</servlet-name>
  10.     <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
  11.     <init-param>
  12.       <param-name>contextConfigLocation</param-name>
  13.       <!--对应springmvc配置文件名-->
  14.       <param-value>classpath:spring-mvc.xml</param-value>
  15.     </init-param>
  16.     <!--配置容器在启动的时候就加载这个servlet并实例化-->
  17.     <load-on-startup>1</load-on-startup>
  18.   </servlet>
  20.   <servlet-mapping>
  21.     <servlet-name>springmvc</servlet-name>
  22.     <url-pattern>/</url-pattern>
  23.   </servlet-mapping>
  25. </web-app>

测试SpringMVC配置：TestController

  1. package cn.demo.controller;
  2. import org.springframework.stereotype.Controller;
  3. import org.springframework.web.bind.annotation.RequestMapping;
  4. import org.springframework.web.bind.annotation.RequestMethod;
  6. @Controller
  7. public class TestController {
  9.     @RequestMapping(value="/index",method= RequestMethod.GET)
  10.     public String index(){
  11.         return "index";    //返回实际视图，路径在springmvc配置文件中已配置完成
  12.     }
  13. }

浏览器输入URL：

  1. http://localhost:8080/SSHDemo/index

index.jsp页面如下

  1. <html>
  2. <body>
  3. <h2>Hello World!</h2>
  4. </body>
  5. </html>

运行结果

五、Spring+Spring MVC整合

applicationContext.xml

  1. <?xml version="1.0" encoding="UTF-8"?>
  2. <beans xmlns="http://www.springframework.org/schema/beans"
  3.        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  4.        xmlns:context="http://www.springframework.org/schema/context"
  5.        xmlns:tx="http://www.springframework.org/schema/tx"
  6.        xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd
  7.     http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd
  8.     http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.1.xsd">
  10.     <!-- 自动扫描 -->
  11.     <context:component-scan base-package="cn.demo">
  12.         <!-- 扫描时跳过 @Controller 注解的JAVA类（控制器） -->
  13.         <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
  14.     </context:component-scan>
  15. </beans>

完善web.xml如下

  1. <?xml version="1.0" encoding="UTF-8"?>
  2. <web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee"
  3.          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  4.          xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
  5.     http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">
  7.   <!-- 配置前端控制器DispatcherServlet-->
  8.   <servlet>
  9.     <servlet-name>springmvc</servlet-name>
  10.     <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
  11.     <init-param>
  12.       <param-name>contextConfigLocation</param-name>
  13.       <!--对应springmvc配置文件名-->
  14.       <param-value>classpath:spring-mvc.xml</param-value>
  15.     </init-param>
  16.     <!--配置容器在启动的时候就加载这个servlet并实例化-->
  17.     <load-on-startup>1</load-on-startup>
  18.   </servlet>
  19.   <servlet-mapping>
  20.     <servlet-name>springmvc</servlet-name>
  21.     <url-pattern>/</url-pattern>
  22.   </servlet-mapping>
  25.   <!--加载Spring的配置文件到上下文中去-->
  26.   <context-param>
  27.     <param-name>contextConfigLocation</param-name>
  28.     <param-value>classpath:applicationContext.xml</param-value>
  29.   </context-param>
  32.   <!-- Spring监听器 -->
  33.   <listener>
  34.     <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  35.   </listener>
  38.   <!-- 增加中文乱码过滤器 -->
  39.   <filter>
  40.     <description><!--字符编码过滤器--></description>
  41.     <filter-name>encodingFilter</filter-name>
  42.     <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
  43.     <init-param>
  44.       <param-name>encoding</param-name>
  45.       <param-value>UTF-8</param-value>
  46.     </init-param>
  47.     <init-param>
  48.       <param-name>forceEncoding</param-name>
  49.       <param-value>true</param-value>
  50.     </init-param>
  51.   </filter>
  52.   <filter-mapping>
  53.     <filter-name>encodingFilter</filter-name>
  54.     <url-pattern>/*</url-pattern>
  55.   </filter-mapping>
  57. </web-app>

Spring+Spring MVC配置完成，进行测试

  1. package cn.demo.service;
  2. import org.springframework.stereotype.Service;
  4. @Service
  5. public class TestServiceImpl implements TestService{
  7.     @Override
  8.     public String test1(){
  9.         return "index";
  10.     }
  11. }

注意 ：类上面的标注@Service注解

  1. package cn.demo.controller;
  3. import cn.demo.service.TestService;
  4. import cn.demo.service.TestServiceImpl;
  5. import org.springframework.beans.factory.annotation.Autowired;
  6. import org.springframework.stereotype.Controller;
  7. import org.springframework.web.bind.annotation.RequestMapping;
  8. import org.springframework.web.bind.annotation.RequestMethod;
  10. @Controller
  11. public class TestController {
  13.     @Autowired
  14.     private TestService testService;
  16.     @RequestMapping(value = "/testService",method =RequestMethod.GET)
  17.     public String main(){
  18.         return testService.test1();
  19.     }
  21. }

浏览器输入URL：

  1. http://localhost:8080/SSHDemo/testService

运行结果

六、Spring+SpringMVC+Hibernate整合

完善applicationContext.xml文件，配置dataSource、sessionFactory等

完整applicationContext.xml如下

  1. <?xml version="1.0" encoding="UTF-8"?>
  2. <beans xmlns="http://www.springframework.org/schema/beans"

  36.         <!--配置实体类与数据库表关系-->
  37.         <property name="packagesToScan" value="cn.demo.pojo"/>
  38.     </bean>
  41.     <!-- 自动扫描 -->
