通过IEAD+Maven快速搭建SSM项目的过程(Spring + Spring MVC + Mybatis)
weixin_41583535 人气:0项目效果预览:
通过访问控制层的test/dologin方法进入index.jsp,展示jsp中的“hello,ssm”内容
一、新建项目:
1.打开IDEA,新建一个Maven项目
2.点击next,新建一个为ssmDemo的Maven项目(自己定义项目GroupId和ArtifactId)
3.配置本地Maven路径
4.点击Next,确认项目信息,配置项目名称和项目路径,点击Finish按钮即可创建项目
5.项目创建完成,目录结构如下:
注:如项目目录中未包含src,则项目还在初始化,注意网络连接,稍等片刻即可
二、补充项目结构:
1.在main文件夹下面创建java和resources文件夹
2.使java文件夹为项目资源文件夹(Sources root)
3.使resources文件夹为Resources root
4.在src/java目录下面创建com包,在com包创建controller、dao、po、service、service.impl包
三、完善pom.xml(添加项目依赖--完整pom.xml代码)

效果图:
注1:代码复制完成后,选择右下角的Import Changes
注2:如Import Changes后External还未出现jar包,则选中项目,右键,选择maven,Generate Sources...
四、为项目导入jar包
1.选择项目右键 -- open Module Setting
2.选择Artifact
3.选择项目名,选择outPut LayOut,选择Available Elements -- 选择项目名称 -- 右键 -- put into...
效果图(WEB-INF中添加了lib目录):
五、完善target文件夹
1.选择右侧侧栏的maven
2.选择Lifecycle -- 选择clean(双击)
3.选择Lifecycle -- 选择install(双击)
4.效果图
六、测试项目
1.添加tomcat(run --> editConfigurations --> 点击+ --> 选择tomcat-- local)
2.配置Deployment(点击Deployment -- 选择右下角+ -- 选择Artifact --选择Artifa)
3.配置访问路径:/ssmDemotest
4.启动tomcat,访问:http://localhost:8080/ssmDemotest
七、编写ssm框架所需xml
1.在src/resources文件夹下面添加mybatis包、spring包
2.在src/resources文件夹下面添加log4j.properties、db.properties
3.在mybatis包下添加:mybatis-config.xml
<?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> <!-- 别名 --> <typeAliases> <package name="com.po" /> </typeAliases> </configuration>
4.在spring包下添加:spring-dao.xml
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.0.xsd"> <!-- 1.配置component-scan 扫描service,mapper包 --> <!-- 如不写,则在控制层的@Resource注解则指定不到对应的service类 --> <context:component-scan base-package="com.service" /> <context:component-scan base-package="com.dao" /> <!-- 2.配置 读取properties文件 jdbc.properties --> <context:property-placeholder location="classpath:db.properties" /> <!-- 3.配置 数据源 --> <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource"> <property name="driverClassName" value="${jdbc.driver}" /> <property name="url" value="${jdbc.url}" /> <property name="username" value="${jdbc.username}" /> <property name="password" value="${jdbc.password}" /> </bean> <!-- 4.配置SqlSessionFactory对象 --> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <!-- 4.1.注入数据库连接池 --> <property name="dataSource" ref="dataSource" /> <!-- 4.2.配置MyBaties全局配置文件:mybatis-config.xml --> <property name="configLocation" value="classpath:mybatis/mybatis-config.xml" /> <!-- 4.3.扫描entity包 使用别名 --> <property name="typeAliasesPackage" value="com.po" /> <!-- 4.4.扫描sql配置文件:mapper需要的xml文件 <property name="mapperLocations" value="classpath:com/dao/*.xml" /> --> </bean> <!-- 5.配置Mapper扫描 --> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <!-- 5.1.注入sqlSessionFactory --> <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" /> <!-- 5.2.配置Mapper扫描 --> <property name="basePackage" value="com.dao" /> </bean> </beans>
5.在spring包下添加:spring-service.xml
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.0.xsd"> <!-- 配置Service扫描 --> <context:component-scan base-package="com.service" /> </beans>
6.在spring包下添加:spring-mvc.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:p="http://www.springframework.org/schema/p" 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-4.0.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd"> <!-- 1.配置Controller扫描 --> <context:component-scan base-package="com.controller" /> <!-- 2.配置注解驱动 --> <mvc:annotation-driven /> <!-- 3.配置视图解析器 --> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <!-- 4.1.前缀 --> <property name="prefix" value="/WEB-INF/jsp/" /> <!-- 4.2.后缀 --> <property name="suffix" value=".jsp" /> </bean> </beans>
7. 完善web.xml
<?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>Archetype Created Web Application</display-name> <!-- 1.加载spring容器 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring/spring-dao.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- 2.springmvc前端控制器 --> <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:spring/spring-mvc.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> <!-- 3.设置匹配所有的url --> <servlet-mapping> <servlet-name>default</servlet-name> <url-pattern>*.js</url-pattern> </servlet-mapping> </web-app>
八、启动tomcat,测试xml文件是否正确
1.如启动日志没有错误信息,则xml添加无误
2.如网址:http://localhost:8080/ssmDemotest 正常展示,则xml添加无误
注:由于大部分代码均为复制,可以重启IDEA
九、controller层
1.在controller包新建类:TestController
2.在类顶部(导包语句下面)添加注解:@Controller,@RequestMapping(value = "test")
3.编写方法:
@RequestMapping("dologin") public String dologin() { System.out.println("====test===="); return "index"; }
十、JSP
1.在web-inf下创建目录:jsp
2.在jsp文件下创建:index.jsp
3.在index.jsp下添加:hello,ssm
十一、测试
加载全部内容
