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">

</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.xsdhttp://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsdhttp://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsdhttp://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsdhttp://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 connection
jdbc_driver=com.mysql.jdbc.Driver
jdbc_url=jdbc:mysql://localhost:3306/mybatis
jdbc_user=root
jdbc_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。
