快速集成搭建SSM框架

附上项目结构图：

1.添加maven依赖

<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/maven-v4_0_0.xsd">  <modelVersion>4.0.0</modelVersion>  <groupId>com.chen</groupId>  <artifactId>spring-springmvc-mybatis</artifactId>  <packaging>war</packaging>  <version>1.0-SNAPSHOT</version>  <name>spring-springmvc-mybatis Maven Webapp</name>  <url>http://maven.apache.org</url>  <properties>    <project.build-sourceEncoding>UTF-8</project.build-sourceEncoding>    <project.reporting-outputEncoding>UTF-8</project.reporting-outputEncoding>    <spring.version>4.3.5.RELEASE</spring.version>    <mybatis.version>3.4.1</mybatis.version>    <javaee.version>7.0</javaee.version>    <net.sf.json>2.4</net.sf.json>    <mysql.version>5.1.41</mysql.version>    <pagehelper.varsion>4.1.0</pagehelper.varsion>    <mybatis.spring.version>1.3.1</mybatis.spring.version>    <commons-dbcp.version>1.2.2</commons-dbcp.version>    <aspectj.version>1.8.6</aspectj.version>    <jackson.version>2.9.0</jackson.version>  </properties>  <dependencies>    <!--java ee 依赖-->    <dependency>      <groupId>javax</groupId>      <artifactId>javaee-api</artifactId>      <version>${javaee.version}</version>    </dependency>    <!--json 依赖-->    <dependency>      <groupId>net.sf.json-lib</groupId>      <artifactId>json-lib</artifactId>      <version>${net.sf.json}</version>    </dependency>    <!--mysql 数据库-->    <dependency>      <groupId>mysql</groupId>      <artifactId>mysql-connector-java</artifactId>      <version>${mysql.version}</version>      <scope>runtime</scope>    </dependency>    <!--数据库连接池-->    <dependency>      <groupId>commons-dbcp</groupId>      <artifactId>commons-dbcp</artifactId>      <version>${commons-dbcp.version}</version>    </dependency>    <!--mybatis 依赖-->    <dependency>      <groupId>org.mybatis</groupId>      <artifactId>mybatis</artifactId>      <version>${mybatis.version}</version>    </dependency>    <!--mybatis 分页查询插件-->    <dependency>      <groupId>com.github.pagehelper</groupId>      <artifactId>pagehelper</artifactId>      <version>${pagehelper.varsion}</version>    </dependency>    <!--整合mybatis和spring-->    <dependency>      <groupId>org.mybatis</groupId>      <artifactId>mybatis-spring</artifactId>      <version>${mybatis.spring.version}</version>    </dependency>    <!--spring 依赖-->    <!--底层核心-提供IOC-->    <dependency>      <groupId>org.springframework</groupId>      <artifactId>spring-core</artifactId>      <version>${spring.version}</version>    </dependency>    <dependency>      <groupId>org.springframework</groupId>      <artifactId>spring-beans</artifactId>      <version>${spring.version}</version>    </dependency>    <dependency>      <groupId>org.springframework</groupId>      <artifactId>spring-webmvc</artifactId>      <version>${spring.version}</version>    </dependency>    <dependency>      <groupId>org.springframework</groupId>      <artifactId>spring-context</artifactId>      <version>${spring.version}</version>    </dependency>    <dependency>      <groupId>org.springframework</groupId>      <artifactId>spring-jdbc</artifactId>      <version>${spring.version}</version>    </dependency>    <dependency>      <groupId>org.springframework</groupId>      <artifactId>spring-tx</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-test</artifactId>      <version>${spring.version}</version>    </dependency>    <dependency>      <groupId>org.springframework</groupId>      <artifactId>spring-aop</artifactId>      <version>${spring.version}</version>    </dependency>    <dependency>      <groupId>org.aspectj</groupId>      <artifactId>aspectjweaver</artifactId>      <version>${aspectj.version}</version>    </dependency>    <!--单元测试-->      <dependency>          <groupId>junit</groupId>          <artifactId>junit</artifactId>          <version>RELEASE</version>      </dependency>    <!--jackson 依赖-->    <dependency>      <groupId>com.fasterxml.jackson.core</groupId>      <artifactId>jackson-core</artifactId>      <version>${jackson.version}</version>    </dependency>    <dependency>      <groupId>com.fasterxml.jackson.core</groupId>      <artifactId>jackson-databind</artifactId>      <version>${jackson.version}</version>    </dependency>  </dependencies>  <build>    <finalName>spring-springmvc-mybatis</finalName>    <plugins>      <plugin>        <groupId>org.apache.maven.plugins</groupId>        <artifactId>maven-compiler-plugin</artifactId>        <configuration>            <source>1.8</source>            <target>1.8</target>        </configuration>      </plugin>    </plugins>  </build></project>

2.配置数据库连接信息jdbc.properties
