1. 在IDEA中创建一个空白工程,在空白工程新建maven父工程,父工程中创建子工程:
maven父子工程的创建:地址
maven添加依赖:地址
两种类型:
qucikstart:
- model:javabean
- service:业务逻辑
- dao:数据库管理
webapp:
- manager:controller
- api:接口
2. manager:配置springMVC
- pom.xml中配置spring/springmvc依赖
- 创建springmvc配置文件:springMVC.xml(扫描controller注解、注解映射器和注解适配器、视图解析器 )
<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"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-4.3.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-4.3.xsd
http://www.springframework.org/schema/aop
http://www.springframework.org/schema/aop/spring-aop-5.1.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx-5.1.xsd ">
<!-- 扫描controller注解,多个包中间使用半角逗号分隔 -->
<context:component-scan base-package="com.moke.edu.web.controller"/>
<!--注解映射器、注解适配器 -->
<mvc:annotation-driven></mvc:annotation-driven>
<!-- 视图解析器 -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="viewClass" value="org.springframework.web.servlet.view.JstlView" />
<property name="prefix" value="/WEB-INF/jsp/" />
<property name="suffix" value=".jsp" />
</bean>
</beans>
- 在web.xml中加载配置文件,即配置前端控制器
<servlet>
<servlet-name>DispatcherServlet</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>DispatcherServlet</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
3.dao:配置mybatis
- pom.xml中配置mybatis依赖、model依赖
- 创建需要的Mapper接口文件、Mapper映射文件(可以创建一个BaseMapper)
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper
PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.moke.edu.mapper.UserMapper"><!-- 1 -->
<!-- 根据id获取用户信息 -->
<select id="findById" parameterType="int" resultType="com.moke.edu.model.User">
select * from t_user where id = #{id}
</select>
</mapper>
- 注意:maven编译时不会加入xml文件,需要在pom.xml的build中配置:
<resources>
<resource>
<directory>src/main/java</directory>
<includes>
<include>**/*.xml</include>
</includes>
</resource>
</resources>
4.service:
- pom.xml中配置dao依赖[注入dao]、springbean(@Autowire)、context(@Service)、tx(@Translation)依赖
- 创建所需要的service接口、service实现类(可以创建一个BaseService、BaseServiceImp)
5. manager:添加其它依赖包
- 添加service依赖[注入service]
- 添加数据库驱动、数据库连接池
- 添加jstl标签库
- 添加taglib动态代理
- 添加log4j日志
- 添加json支持
- 添加mybatis和spring整合
6. manager:其它配置文件:
- mybatis配置文件:mybatis(加载mapper.xml映射文件)
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
<typeAliases>
<package name="com.moke.edu.model"/>
</typeAliases>
<!-- 加载mapper.xml映射文件 -->
<mappers>
<package name="com.moke.edu.mapper"/>
</mappers>
</configuration>
- log4j配置文件:log4j.properties
# Global logging configuration
# 开发环境下日志级别为DEBUG,生产环境下设置为info
log4j.rootLogger=DEBUG, stdout
# Console output...
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%5p [%t] - %m%n
- 数据库连接配置文件:db.properties
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/edu1
jdbc.username=root
jdbc.password=123
- spring配置文件:applicationContext(加载配置文件(db、log4j)、数据源、sqlSessionFactory[数据源、mybatis配置文件]、自动扫描service、自动扫描mapper.java)

- web.xml中加载spring配置文件

<param-name>contextConfigLocation</param-name>
<param-value>classpath:applictionContext.xml
</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
7. manager:整合页面(由前端完成)
- webapp:js文件、图片…
- webapp/WEB-INF:html…
