使用maven快速构建SSM项目

这里我就假设大家都已经配置好Maven，就不在重复说明了。若没有配置可以参考《首次使用maven的配置过程》。

1.新建Maven项目

工作区–右键—new—other–搜索maven

现在maven项目新建完毕，需要将其转化为一个动态web项目。

2.将Maven项目转为动态web项目

选中项目—右键–properties—project facets—Dynamic Web Module—（RunTime）Appache Tomcat—…

上面的步骤一般首次都会报如下错误，我们重复刚刚的操作就行

重复步骤如下：注意依然要再次选择Dynamic Web Module ,然后选择 Appache Tomcat，再重复下面的

这样Maven转为Web项目就成功了。现在来配置一下SSM架构了。

3.构建SSM框架

3.1配置pom.xml

<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 http://maven.apache.org/xsd/maven-4.0.0.xsd">  <modelVersion>4.0.0</modelVersion>  <groupId>com.java</groupId>  <artifactId>Maven_SSM_Demo</artifactId>  <version>0.0.1-SNAPSHOT</version>  <packaging>jar</packaging>  <name>Maven_SSM_Demo</name>  <url>http://maven.apache.org</url>  <properties>       <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>    <!-- 声明spring 对应版本：标签名可以任意取 -->    <spring-version>4.3.8.RELEASE</spring-version>  </properties>  <dependencies>    <dependency>      <groupId>junit</groupId>      <artifactId>junit</artifactId>      <version>3.8.1</version>      <scope>test</scope>    </dependency>    <dependency>            <groupId>org.springframework</groupId>            <artifactId>spring-context</artifactId>            <version>4.3.8.RELEASE</version>        </dependency>        <!-- ssm开发 Spring jar / Spring MVCjar SpringJDBC jar -->        <dependency>            <groupId>org.springframework</groupId>            <artifactId>spring-context</artifactId>            <version>${spring-version}</version>        </dependency>        <dependency>            <groupId>org.springframework</groupId>            <artifactId>spring-core</artifactId>            <version>${spring-version}</version>        </dependency>        <dependency>            <groupId>org.springframework</groupId>            <artifactId>spring-beans</artifactId>            <version>${spring-version}</version>        </dependency>        <dependency>            <groupId>org.springframework</groupId>            <artifactId>spring-web</artifactId>            <version>${spring-version}</version>        </dependency>        <dependency>            <groupId>org.springframework</groupId>            <artifactId>spring-webmvc</artifactId>            <version>${spring-version}</version>        </dependency>        <dependency>            <groupId>org.springframework</groupId>            <artifactId>spring-jdbc</artifactId>            <version>${spring-version}</version>        </dependency>        <!-- mybaits jar -->        <dependency>            <groupId>org.mybatis</groupId>            <artifactId>mybatis</artifactId>            <version>3.4.1</version>        </dependency>        <!-- mybatis和Spring集成需要的jar -->        <dependency>            <groupId>org.mybatis</groupId>            <artifactId>mybatis-spring</artifactId>            <version>1.3.0</version>        </dependency>        <!--c3p0 jar -->        <dependency>            <groupId>com.mchange</groupId>            <artifactId>c3p0</artifactId>            <version>0.9.5.2</version>        </dependency>        <!-- jackson @ResponseBody -->        <dependency>            <groupId>com.fasterxml.jackson.core</groupId>            <artifactId>jackson-databind</artifactId>            <version>2.8.7</version>        </dependency>        <!-- mysql 数据库 -->        <dependency>            <groupId>mysql</groupId>            <artifactId>mysql-connector-java</artifactId>            <version>5.1.38</version>        </dependency>  </dependencies></project>

3.2配置web.xml

<?xml version="1.0" encoding="UTF-8"?><web-app id="WebApp_ID" version="3.0" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"><display-name>Maven_SSM_Demo</display-name>  <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>  <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:applicationContext.xml</param-value>    </init-param>  </servlet>  <servlet-mapping>    <servlet-name>SpringMVC</servlet-name>    <url-pattern>/</url-pattern>  </servlet-mapping>  <filter>    <filter-name>HiddenHttpMethod</filter-name>    <filter-class>org.springframework.web.filter.HiddenHttpMethodFilter</filter-class>  </filter>  <filter-mapping>    <filter-name>HiddenHttpMethod</filter-name>    <url-pattern>/*</url-pattern>  </filter-mapping>  <welcome-file-list>    <welcome-file>index.html</welcome-file>    <welcome-file>index.htm</welcome-file>    <welcome-file>index.jsp</welcome-file>    <welcome-file>default.html</welcome-file>    <welcome-file>default.htm</welcome-file>    <welcome-file>default.jsp</welcome-file>  </welcome-file-list></web-app>

3.3有关Maven与Web基础的配置

选中项目—右键—properties—deployment Assembly–add(目的：让maven的jar映射到web的lib下）

最后，apply —ok保存即可

3.4新建Source Folder

在资源夹是专门用来放置配置文件的

3.5 applicationContext.xml配置

<?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:aop="http://www.springframework.org/schema/aop"    xmlns:mvc="http://www.springframework.org/schema/mvc"    xmlns:jdbc="http://www.springframework.org/schema/jdbc"    xsi:schemaLocation="http://www.springframework.org/schema/jdbc http://www.springframework.org/schema/jdbc/spring-jdbc-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/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/aop http://www.springframework.org/schema/aop/spring-aop.xsd">    <!-- springmvc处理静态资源 -->    <mvc:default-servlet-handler />    <mvc:annotation-driven></mvc:annotation-driven>    <context:component-scan base-package="com.java"></context:component-scan>    <!-- 第一步 加载jdbc.properties -->    <context:property-placeholder location="classpath:jdbc.properties" />    <!-- 第二步，配置C3P0数据连接池 -->    <!-- 需要数据源 C3P0 -->    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">        <property name="driverClass" value="${jdbc_driver}"></property>        <property name="jdbcUrl" value="${jdbc_url}"></property>        <property name="password" value="${jdbc_password}"></property>        <property name="user" value="${jdbc_user}"></property>    </bean>    <!-- 第三步 SpringJDBC   -->    <bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate">        <property name="dataSource" ref="dataSource"></property>    </bean>    <!-- mybatis集成 -->    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">        <property name="dataSource" ref="dataSource"></property>        <!-- mappers 配置文件映射 -->        <property name="mapperLocations" value="classpath:com/java/dao/*.xml"></property>        <!-- 别名设置 将该包内所有的类定义了别名，别名就是其类名 -->        <property name="typeAliasesPackage" value="com.java.bean"></property>    </bean>    <!-- 配置对应的SqlSession -->    <bean id="sqlSession" class="org.mybatis.spring.SqlSessionTemplate">        <constructor-arg index="0" ref="sqlSessionFactory"></constructor-arg>    </bean>    <!-- 自动扫描，完成代码Mapper -->    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">        <property name="basePackage" value="com.java.dao"></property>        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>    </bean></beans>

3.6 jdbc.properties配置

# remark#driver=oracle.jdbc.driver.OracleDriver#url=jdbc:oracle:thin:@localhost:1521:orcl#user=test1#password=test1#mysql connectionjdbc_driver=com.mysql.jdbc.Driverjdbc_url=jdbc:mysql://localhost:3306/mybatisjdbc_user=rootjdbc_password=123

这样使用Maven构建SSM项目就成功来。可以自己可以测试一下。

我的小demo项目–《Maven_SSM_Demo》，项目做了测试，有相关的sql文件，直接可以直接测试。
