在Intellij idea中用maven创建ssm项目

第一步：创建maven项目
1.1 打开idea，选择创建项目：Create New Project

1.2 在打开的对话框中选中maven，配置jdk、maven home，选择web app骨架等。

1.3 填写项目的 g、a、v 即：包名、模块名、版本号。

1.4 为了加快maven的构建，添加本地的catelog=local

1.5 填写项目的名称

1.6 在新建的maven项目中，修改web.xml信息 改为最新的版本

<web-app 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"         version="3.0"         metadata-complete="true">

第二步：配置pom.xml文件，导入依赖的jar包。

<dependencies>    <!--配置依赖 -->    <dependency>      <groupId>junit</groupId>      <artifactId>junit</artifactId>      <version>4.10</version>      <scope>test</scope>    </dependency>    <!--一、配置数据库相关 -->    <!--1.1配置mysql驱动 -->    <dependency>      <groupId>mysql</groupId>      <artifactId>mysql-connector-java</artifactId>      <version>5.1.32</version>      <scope>runtime</scope>    </dependency>    <!--1.2 配置c3p0数据库连接池 -->    <dependency>      <groupId>c3p0</groupId>      <artifactId>c3p0</artifactId>      <version>0.9.1.2</version>    </dependency>    <!-- 二、配置mybatis相关配置-->    <!-- 2.1配置mybatis-->    <dependency>      <groupId>org.mybatis</groupId>      <artifactId>mybatis</artifactId>      <version>3.2.8</version>    </dependency>    <!--2.2 配置mybatis 与spring的整合包 -->    <dependency>      <groupId>org.mybatis</groupId>      <artifactId>mybatis-spring</artifactId>      <version>1.2.2</version>    </dependency>    <!--三、配置spring相关 -->    <!--3.1 spring core -->    <dependency>      <groupId>org.springframework</groupId>      <artifactId>spring-core</artifactId>      <version>4.1.3.RELEASE</version>    </dependency>    <!--3.2 spring ioc -->    <dependency>      <groupId>org.springframework</groupId>      <artifactId>spring-beans</artifactId>      <version>4.1.3.RELEASE</version>    </dependency>    <dependency>      <groupId>org.springframework</groupId>      <artifactId>spring-context</artifactId>      <version>4.1.3.RELEASE</version>    </dependency>    <!--3.3 spring jdbc -->    <dependency>      <groupId>org.springframework</groupId>      <artifactId>spring-jdbc</artifactId>      <version>4.1.3.RELEASE</version>    </dependency>    <!-- 3.4 spring 事务-->    <dependency>      <groupId>org.springframework</groupId>      <artifactId>spring-tx</artifactId>      <version>4.1.3.RELEASE</version>    </dependency>    <!--spring web -->    <dependency>      <groupId>org.springframework</groupId>      <artifactId>spring-web</artifactId>      <version>4.1.3.RELEASE</version>    </dependency>    <!--spring-mvc -->    <dependency>      <groupId>org.springframework</groupId>      <artifactId>spring-webmvc</artifactId>      <version>4.1.3.RELEASE</version>    </dependency>    <!--spring-test-->    <dependency>      <groupId>org.springframework</groupId>      <artifactId>spring-test</artifactId>      <version>4.1.3.RELEASE</version>      <scope>test</scope>    </dependency>    <!-- spring-jackson -->    <dependency>      <groupId>com.fasterxml.jackson.core</groupId>      <artifactId>jackson-core</artifactId>      <version>2.8.3</version>    </dependency>    <dependency>      <groupId>com.fasterxml.jackson.core</groupId>      <artifactId>jackson-databind</artifactId>      <version>2.4.2</version>    </dependency>    <dependency>      <groupId>com.fasterxml.jackson.core</groupId>      <artifactId>jackson-annotations</artifactId>      <version>2.4.0</version>    </dependency>    <!--文件上传相关 -->    <dependency>      <groupId>commons-fileupload</groupId>      <artifactId>commons-fileupload</artifactId>      <version>1.3.1</version>    </dependency>    <!--jsp 相关 -->    <dependency>      <groupId>javax.servlet</groupId>      <artifactId>servlet-api</artifactId>      <version>3.0</version>    </dependency>    <dependency>      <groupId>javax.servlet.jsp</groupId>      <artifactId>jsp-api</artifactId>      <version>2.1</version>    </dependency>    <dependency>      <groupId>javax.servlet.jsp.jstl</groupId>      <artifactId>jstl-api</artifactId>      <version>1.2</version>    </dependency>    <dependency>      <groupId>taglibs</groupId>      <artifactId>standard</artifactId>      <version>1.1.2</version>    </dependency>    <!--日志相关 -->    <dependency>      <groupId>org.slf4j</groupId>      <artifactId>slf4j-api</artifactId>      <version>1.7.2</version>    </dependency>    <dependency>      <groupId>ch.qos.logback</groupId>      <artifactId>logback-core</artifactId>      <version>1.1.7</version>    </dependency>    <dependency>      <groupId>ch.qos.logback</groupId>      <artifactId>logback-classic</artifactId>      <version>1.1.7</version>    </dependency>  </dependencies>

第三步：ssm框架的整合。
版本号:
mybatis :3.2.8
spring:4.2.X

3.1 配置mybatis的核心配置文件。

在src/main/resource/
创建mybatis文件夹，创建mybatis-config.xml配置文件

内容如下：

<?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>    <!--配置mybatis的一些设置 -->    <settings>        <!--支持主键自增 -->        <setting name="useGeneratedKeys" value="true"/>        <!--支持驼峰转换 -->        <setting name="mapUnderscoreToCamelCase" value="true"/>        <!-- 设置列明自定义-->        <setting name="useColumnLabel" value="true"/>    </settings>    <!-- 类型映射-->    <typeAliases>        <package name="com.jlju.docmanager.bean"/>    </typeAliases></configuration>

3.2 配置数据库连接信息：jdbc.properties

driverClass=com.mysql.jdbc.DriverjdbcUrl=jdbc:mysql://localhost:3306/docmanager?useUnicode=true&characterEncoding=utf8user=rootpassword=x5

3.3 spring 与mybatis整合：spring-jdbc.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:context="http://www.springframework.org/schema/context"       xsi:schemaLocation="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">       <!-- 加载jdbc配置文件-->       <context:property-placeholder location="classpath:jdbc.properties"/>       <!-- 配置数据源-->       <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">               <!--数据库连接属性 -->              <property name="driverClass" value="${driverClass}"/>              <property name="jdbcUrl" value="${jdbcUrl}"/>              <property name="user" value="${user}"/>              <property name="password" value="${password}"/>              <!-- 数据源连接配置-->              <property name="autoCommitOnClose" value="false"/>              <property name="checkoutTimeout" value="3000"/>              <property name="acquireRetryAttempts" value="3"/>              <property name="maxPoolSize" value="5"/>              <property name="minPoolSize" value="3"/>       </bean>       <!--配置mybatis -->       <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">              <!-- 配置数据源-->              <property name="dataSource" ref="dataSource"/>              <!--配置属性文件位置 -->              <property name="configLocation" value="classpath:mybatis/mybatis-config.xml"/>              <!-- 配置mapper文件位置-->              <property name="mapperLocations" value="classpath:mybatis/mapper/*.xml"/>       </bean>       <!-- 配置dao接口自动生成-->       <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">              <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>              <property name="basePackage" value="com.jlju.docmanager.dao"/>       </bean></beans>

3.3 事务配置 spring-tx.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:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx"       xsi:schemaLocation="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/tx http://www.springframework.org/schema/tx/spring-tx.xsd">       <!-- 配置事务-->       <!-- 配置包扫描-->       <context:component-scan base-package="com.jlju.docmanager.service.impl"/>       <!--配置事务管理器 -->       <bean id="transactionManager"  class="org.springframework.jdbc.datasource.DataSourceTransactionManager">              <!-- 配置要引用的datasource-->              <property name="dataSource" ref="dataSource"/>       </bean>        <!--启动注解式事务管理器 -->       <tx:annotation-driven transaction-manager="transactionManager"/></beans>

3.4 spring mvc配置:srping-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:context="http://www.springframework.org/schema/context"       xmlns:tx="http://www.springframework.org/schema/tx"       xmlns:mvc="http://www.springframework.org/schema/mvc"       xsi:schemaLocation="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/tx http://www.springframework.org/schema/tx/spring-tx.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd">    <!-- 配置mvc-->    <!-- 配置注解-->    <mvc:annotation-driven/>    <!--配置包扫描 -->    <context:component-scan base-package="com.jlju.docmanager.controller"/>    <!-- 配置视图解析器-->    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">        <property name="prefix" value="/WEB-INF/jsp/"/>        <property name="suffix" value=".jsp"/>    </bean>    <!--配置静态资源解析器 -->    <mvc:default-servlet-handler/></beans>

3.5 spring-mvc 前端控制器配置：web.xml中添加配置

<web-app 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"         version="3.0"         metadata-complete="true">  <display-name>DocManager</display-name>  <!-- 配置servlet 前端控制器-->    <servlet>        <servlet-name>DispatcherServlet</servlet-name>        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>        <init-param>            <param-name>contextConfigLocation</param-name>            <param-value>classpath:spring/spring-*.xml</param-value>        </init-param>        <load-on-startup>1</load-on-startup>    </servlet>    <servlet-mapping>        <servlet-name>DispatcherServlet</servlet-name>        <url-pattern>/</url-pattern>    </servlet-mapping></web-app>

3.6 事务测试

 */@RunWith(SpringJUnit4ClassRunner.class)@ContextConfiguration(value = {"classpath:spring/spring-dao.xml","classpath:spring/spring-tx.xml"})public class UsersSerivceTest {    @Autowired    private UsersSerivce us;    @Test    public void testQueryAllUsers() throws Exception {        List<Users> userses = us.queryAllUsers();        System.out.println(userses.size());    }    @Test    public void testInsertUsers() throws Exception {        Users u = new Users();        u.setPassword("123");        u.setRealName("丁春秋");        u.setUsername("1235");         us.insertUsers(u);        System.out.println();    }}
