maven整合ssm(spring+spring mvc+mybatis)框架的步骤

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

  1. 工具
    Eclipse
    Oracle11g
    Spring
    Mybatis
    Log4j
    Maven
    Tomcat 7
  2. 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)
    本地仓库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>
    阿里镜像还要注意jdk版本要与环境变量配置的jdk版本一致

jdk版本要与环境变量配置的一致
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

在这里插入图片描述在这里插入图片描述

  1. 创建maven项目

file->new->other->maven->maven project

点两下next在这里插入图片描述然后输入坐标,groupId artifactId 以及version(groupid一般是公司域名的倒写,artifactid是项目名)
在这里插入图片描述在src/main下面创建名为java的folder文件夹
在这里插入图片描述这样前期工作就做完了

  1. 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

  </build>
</project>

这样当你保存的时候,eclipse就会下载对应的jar包了

  1. 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.
