IDEA搭建-SSM三步走之步骤02
IDEA搭建-SSM三步走之步骤02
使用 IDEA搭建SSM项目[ SSM 全名: Spring+SpringMVC+MyBatis ]
环境: IDEA, JDK1.8, Maven3.6,Tomcat7.0
步骤分为三步:
01: 创建maven 工程;
02: 创建spring工程
03: 写个查询demo测试
第二步,创建spring工程
基本目录结构
目录位置\simplessm\src
└─main
├─java
│ └─com
│ └─dafei
│ ├─controller
│ ├─dao
│ ├─model
│ └─service
│ └─impl
├─resources
│ └─mapper
└─webapp
└─WEB-INF
└─jsp
第二步最终所有文件结构
目录位置\simplessm\src
└─main
├─java
│ └─com
│ └─dafei
│ ├─controller
│ ├─dao
│ ├─model
│ └─service
│ └─impl
├─resources
│ │ jdbc.properties
│ │ log4j.properties
│ │ spring-mvc.xml
│ │ spring-mybatis.xml
│ │
│ └─mapper
└─webapp
│ index.jsp
│
└─WEB-INF
│ web.xml
配置 pom.xml 文件,内容如下
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0

创建数据库配置 和 日志配置文件
数据库配置文件jdbc.properties
日志配置文件log4j.properties
jdbc.properties 文件内容
driver=com.mysql.jdbc.Driver url=jdbc:mysql://localhost:3306/feissm?characterEncoding=utf8&useSSL=false #数据库的用户名 和 密码 username=afei2 password=123456 #定义初始连接数 initialSize=0 #定义最大连接数 maxActive=20 #定义最大空闲 maxIdle=20 #定义最小空闲 minIdle=1 #定义最长等待时间 maxWait=60000
log4j.properties 问内容
#日志输出级别
log4j.rootLogger=debug,stdout,D,E
#设置stdout的日志输出控制台
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
#输出日志到控制台的方式，默认为System.out
log4j.appender.stdout.Target = System.out
#设置使用灵活布局
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
#灵活定义输出格式
log4j.appender.stdout.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss,SSS} -[%p] method:[%c (%rms)] - %m%n
创建 spring-mvc 和 spring-mybatis
spring-mvc 文件内容
<?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:context="http://www.springframework.org/schema/context" xmlns:mvc="http://www.springframework.org/schema/mvc" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd"> <!-- 自动扫描 --> <context:component-scan base-package="com.dafei"/> <!-- 开启SpringMVC注解模式 --> <mvc:annotation-driven/> <!-- 静态资源默认servlet配置 --> <mvc:default-servlet-handler /> <!-- 配置返回视图的路径，以及识别后缀是jsp文件 --> <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>
spring-mybatis 文件内容
<?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:tx="http://www.springframework.org/schema/tx" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"> <!-- 加载properties文件 --> <bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> <property name="location" value="classpath:jdbc.properties"/> </bean> <!-- 配置数据源 --> <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource"> <property name="driverClassName" value="${driver}"/> <property name="url" value="${url}"/> <property name="username" value="${username}"/> <property name="password" value="${password}"/> </bean> <!-- mybatis和spring完美整合，不需要mybatis的配置映射文件 --> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="dataSource" ref="dataSource"/> <!-- 扫描model包 --> <property name="typeAliasesPackage" value="com.dafei"/> <!-- 扫描sql配置文件:mapper需要的xml文件 --> <property name="mapperLocations" value="classpath:mapper/*.xml"/> </bean> <!-- Mapper动态代理开发，扫描dao接口包--> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <!-- 注入sqlSessionFactory --> <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/> <!-- 给出需要扫描Dao接口包 --> <property name="basePackage" value="com.dafei.dao"/> </bean> <!-- 事务管理 --> <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <!--数据库连接池--> <property name="dataSource" ref="dataSource"/> </bean> </beans>
修改web.xml
web.xml文件内容
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd" > <web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" version="3.1"> <display-name>Archetype Created Web Application</display-name> <!--项目的欢迎页，项目运行起来后访问的页面--> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> <!-- 注册ServletContext监听器，创建容器对象，并且将ApplicationContext对象放到Application域中 --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- 指定spring核心配置文件 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring-mybatis.xml</param-value> </context-param> <!-- 解决乱码的过滤器 --> <filter> <filter-name>CharacterEncodingFilter</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> <init-param> <param-name>forceEncoding</param-name> <param-value>true</param-value> </init-param> </filter> <filter-mapping> <filter-name>CharacterEncodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- 配置前端控制器 --> <servlet> <servlet-name>springmvc</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <!-- 指定配置文件位置和名称 如果不设置,默认找/WEB-INF/<servlet-name>-servlet.xml --> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring-mvc.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> <async-supported>true</async-supported> </servlet> <servlet-mapping> <servlet-name>springmvc</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> </web-app>
运行测试
如果在第一步已经配置Tomcat,这里可以直接启动
