maven整合SSM框架
因为最近练习用到maven与ssm,脑子不够用,所以写篇博客记录一下,这也是我的第一篇博客
- 工具
Eclipse
Oracle11g
Spring
Mybatis
Log4j
Maven
Tomcat 7 - 配置maven
下载maven,解压maven到本地目录,并修改maven conf目录下的settings.xml文件
首先配置本地仓库localRepository标签(项目依赖jar包插件的下载位置)
由于远程仓库国外服务器下载速度慢,可以配置国内镜像,在settings.xml添加代码
<mirror> <id>alimaven</id> <name>aliyun maven</name> <url>http://maven.aliyun.com/nexus/content/groups/public/</url> <mirrorOf>central</mirrorOf> </mirror>
还要注意jdk版本要与环境变量配置的jdk版本一致
3. Eclipse集成maven
eclipse默认是集成maven,但我们可以自己集成自己下载的maven
- 创建maven项目
file->new->other->maven->maven project
点两下next然后输入坐标,groupId artifactId 以及version(groupid一般是公司域名的倒写,artifactid是项目名)
在src/main下面创建名为java的folder文件夹
这样前期工作就做完了
- 配置pom.xml
因为maven项目是基于项目对象模型即pom.xml,通过配置pom.xml来构建项目的依赖

这样当你保存的时候,eclipse就会下载对应的jar包了
- 集成spring,springmvc,mybatis
在resources下面添加,spring-mvc.xml配置文件(前端控制器的配置文件)
<?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">
<!-- 配置注解驱动 -->
<mvc:annotation-driven />
<!-- 配置Controller扫描 -->
<context:component-scan base-package="com.nwf.controller" />
<!-- 配置视图解析器 -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<!-- 前缀 -->
<property name="prefix" value="/WEB-INF/view/" />
<!-- 后缀 -->
<property name="suffix" value=".jsp" />
</bean>
</beans>
然后创建spring-mybatis.xml(spring集成mybatis框架),数据源DataSource中的数据需要从jdbc.properties中读取,所以需要在resources中添加对应文件
<?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 读取properties文件 jdbc.properties -->
<context:property-placeholder location="classpath:jdbc.properties" />
<!-- 配置 数据源 -->
<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<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>
<!-- 配置SqlSessionFactory -->
<bean class="org.mybatis.spring.SqlSessionFactoryBean">
<!-- 设置MyBatis核心配置文件 -->
<!-- <property name="configLocation" value="classpath:resources/mybatis/mybatis-config.xml" /> -->
<!-- 设置数据源 -->
<property name="dataSource" ref="dataSource" />
<!-- 它表示我们的Mapper文件存放的位置,当我们的Mapper文件跟对应的Mapper接口处于同一位置的时候可以不用指定该属性的值。 -->
<!-- <property name="mapperLocations" value="classpath:/mapper/**/*.xml" /> -->
<!-- 那么在Mapper文件里面就可以直接写对应的类名 而不用写全路径名了 -->
<!-- 跟mybatis中<typeAliases>作用一样 -->
<property name="typeAliasesPackage" value="com.nwf.pojo"/>
</bean>
<!-- 配置Mapper扫描 -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<!-- 设置Mapper扫描包 -->
<property name="basePackage" value="com.nwf.mapper" />
</bean>
</beans>
jdbc.driver=oracle.jdbc.driver.OracleDriver
jdbc.url=jdbc:oracle:thin:@localhost:1521:XE
jdbc.username=
jdbc.password=
在resources下添加spring-service.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">
<!-- 配置service扫描 -->
<context:component-scan base-package="com.nwf.service.*" />
</beans>
最后需要在项目配置文件web.xml配置信息
注意web.xml有dtd语法检查,要注意各个参数的前后顺序,否则报错
<!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>
<display-name>Archetype Created Web Application</display-name>
<!-- 配置spring -->
<context-param>
<param-name>contextConfigLocation</param-name>
<!-- 全部引入 -->
<param-value>classpath:spring-*.xml</param-value>
</context-param>
<!-- 配置过滤器,解决post的乱码问题 -->
<filter>
<filter-name>encoding</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>encoding</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<!-- 配置监听器加载spring -->
<listener>
<!-- <listener-class>com.jeenotes.common.listener.WebContextListener</listener-class> -->
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!-- 配置SpringMVC -->
<servlet>
<servlet-name>mvc</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring-mvc.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>mvc</servlet-name>
<!-- 所有的请求都进入springMVC -->
<url-pattern>/</url-pattern>
</servlet-mapping>
</web-app>
这样就搭好了maven与ssm的架子了,注意配置文件中的注解扫描的包要配置好.另外我将jsp文件放入了web-inf下创建的view文件夹中,也需要注意一下.
