springMVC学习笔记---day02 springMVC+spring+mybatis整合开发框架搭建

一：springmvc+spring+mybatis整合

1.创建动态web项目，导入jar包

2.在web.xml中配置spring监听器以及springmvc核心控制器

<?xml version="1.0" encoding="UTF-8"?><web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns="http://java.sun.com/xml/ns/javaee"xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"id="WebApp_ID" version="2.5"><display-name>ssm-Demo</display-name><welcome-file-list><welcome-file>index.html</welcome-file><welcome-file>index.htm</welcome-file><welcome-file>index.jsp</welcome-file><welcome-file>default.html</welcome-file><welcome-file>default.htm</welcome-file><welcome-file>default.jsp</welcome-file></welcome-file-list><!-- 初始化spring容器，配置spring核心配置文件位置 --><context-param><param-name>contextConfigLocation</param-name><param-value>classpath:application-context.xml</param-value></context-param><listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener><!-- 解决POST提交中文时的乱码问题 --><filter><filter-name>characterEncoding</filter-name><filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class><init-param><param-name>encoding</param-name><param-value>UTF-8</param-value></init-param></filter><filter-mapping><filter-name>characterEncoding</filter-name><url-pattern>*.do</url-pattern></filter-mapping><!-- 配置springmvc核心控制器 --><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-config.xml</param-value></init-param><!-- 配置使读取配置文件时实例化springmvc --><load-on-startup>1</load-on-startup></servlet><servlet-mapping><servlet-name>springmvc</servlet-name><url-pattern>*.do</url-pattern></servlet-mapping></web-app>

3.创建包，配置其他配置文件

a、配置mybatis核心配置文件 -- mybatis-config.xml

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE configurationPUBLIC "-//mybatis.org//DTD Config 3.0//EN""http://mybatis.org/dtd/mybatis-3-config.dtd"><configuration><!-- 配置包下自动别名 --><typeAliases><package name="com.ssm.pojo"/></typeAliases></configuration>

b、配置springmvc核心配置文件 -- springmvc-config.xml

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc"      xmlns:context="http://www.springframework.org/schema/context"      xmlns:aop="http://www.springframework.org/schema/aop"       xmlns:tx="http://www.springframework.org/schema/tx"      xmlns:task="http://www.springframework.org/schema/task"      xsi:schemaLocation="http://www.springframework.org/schema/beans           http://www.springframework.org/schema/beans/spring-beans-3.0.xsd           http://www.springframework.org/schema/mvc           http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd           http://www.springframework.org/schema/context           http://www.springframework.org/schema/context/spring-context-3.0.xsd           http://www.springframework.org/schema/aop           http://www.springframework.org/schema/aop/spring-aop-3.0.xsd           http://www.springframework.org/schema/tx           http://www.springframework.org/schema/tx/spring-tx-3.0.xsd          http://www.springframework.org/schema/task          http://www.springframework.org/schema/task/spring-task-3.0.xsd"><!-- 配置开启扫描注解 --><context:component-scan base-package="com.ssm" use-default-filters="false"><!-- springmvc的配置文件，因此,配置为只扫描Controller中的注解 --><context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/></context:component-scan><!-- 配置处理器映射器，处理器适配器，使用该配置可以替代处理器适配器、处理器映射器的配置 --><mvc:annotation-driven/><!-- 配置处理器映射器,当使用上面的mvc标签时，可以不用配置处理器映射器和处理器适配器 <bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping"></bean>--><!-- 配置处理器适配器 <bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter"></bean>--><!-- 配置视图解析器 --><bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"><!-- 前缀 --><property name="prefix" value="/WEB-INF/jsp/items" /><!-- 后缀 --><property name="suffix" value=".jsp" /></bean></beans>

c、配置spring核心配置文件 -- application-context.xml

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc"xmlns:context="http://www.springframework.org/schema/context"xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"xmlns:task="http://www.springframework.org/schema/task"xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsdhttp://www.springframework.org/schema/task   http://www.springframework.org/schema/task/spring-task-3.0.xsd"><!-- 导入所有配置文件 --><import resource="config/*.xml"/></beans>

d、配置数据库连接属性 -- jdbc.properties
