前言

今天开始就做一个个人博客实战项目了,首先就项目环境的搭建，万丈高楼平地起。这篇 博客主要讲解基于maven的ssm项目整合。

1、ssm系统架构

这里写图片描述
整合步骤

第一步:

　　MyBatis和Spring整合，通过Spring管理mapper接口。

　　使用mapper的扫描器自动扫描mapper接口在Spring中进行注册。

第二步：

　　通过Spring管理Service接口。

　　使用配置方式将Service接口配置在Spring配置文件中。

　　实现事务控制。

第三步：

　　由于SpringMVC是Spring的模块，无需整合这两个。

项目架构:
这里写图片描述
下面讲解部分包/文件作用

mapper:存放mybatis的mapper文件夹
log4j.properties:log4j日志属性文件
mybatis-conf.xml:mybatis全局配置文件
spring-bean.xml:spring与mybatis整合配置文件
spring-mvc.xml:spring mvc配置文件

下面就开始我们的项目整合吧

2、项目整合

2.1、新建maven项目添加依赖

maven是一个优秀的项目对象管理器工具我可以通过在pom.xml中添加需要的jar包的依赖就可以导入对应的jar包了，非常的方便。
下面就列出整合ssm所对应的依赖

<!-- 添加sevlet支持 -->    <dependency>      <groupId>javax.servlet</groupId>      <artifactId>javax.servlet-api</artifactId>      <version>3.1.0</version>    </dependency>    <!-- 添加jsp支持 -->    <dependency>      <groupId>javax.servlet.jsp</groupId>      <artifactId>javax.servlet.jsp-api</artifactId>      <version>2.3.1</version>    </dependency>    <!-- 添加jstl支持 -->    <dependency>      <groupId>javax.servlet</groupId>      <artifactId>jstl</artifactId>      <version>1.1.2</version>    </dependency>    <dependency>      <groupId>taglibs</groupId>      <artifactId>standard</artifactId>      <version>1.1.2</version>    </dependency>    <!-- 添加spring支持 -->    <dependency>      <groupId>org.springframework</groupId>      <artifactId>spring-core</artifactId>      <version>4.3.0.RELEASE</version>    </dependency>    <dependency>      <groupId>org.springframework</groupId>      <artifactId>spring-beans</artifactId>      <version>4.3.0.RELEASE</version>    </dependency>    <dependency>      <groupId>org.springframework</groupId>      <artifactId>spring-context</artifactId>      <version>4.3.0.RELEASE</version>    </dependency>    <dependency>      <groupId>org.springframework</groupId>      <artifactId>spring-context-support</artifactId>      <version>4.3.0.RELEASE</version>    </dependency>    <dependency>      <groupId>org.springframework</groupId>      <artifactId>spring-web</artifactId>      <version>4.3.0.RELEASE</version>    </dependency>    <!--spring test支持-->    <dependency>      <groupId>org.springframework</groupId>      <artifactId>spring-test</artifactId>      <version>4.3.0.RELEASE</version>    </dependency>    <!--spring mvc支持-->    <dependency>      <groupId>org.springframework</groupId>      <artifactId>spring-webmvc</artifactId>      <version>4.3.0.RELEASE</version>    </dependency>    <!--spring 事务管理支持-->    <dependency>      <groupId>org.springframework</groupId>      <artifactId>spring-tx</artifactId>      <version>4.3.0.RELEASE</version>    </dependency>    <!--spring jdbc操作支持-->    <dependency>      <groupId>org.springframework</groupId>      <artifactId>spring-jdbc</artifactId>      <version>4.3.0.RELEASE</version>    </dependency>    <!--spring aop编程支持-->    <dependency>      <groupId>org.springframework</groupId>      <artifactId>spring-aop</artifactId>      <version>4.3.0.RELEASE</version>    </dependency>    <dependency>      <groupId>org.springframework</groupId>      <artifactId>spring-aspects</artifactId>      <version>4.3.0.RELEASE</version>    </dependency>    <!-- 添加mybatis支持 -->    <dependency>      <groupId>org.mybatis</groupId>      <artifactId>mybatis</artifactId>      <version>3.4.0</version>    </dependency>    <dependency>      <groupId>org.mybatis</groupId>      <artifactId>mybatis-spring</artifactId>      <version>1.3.0</version>    </dependency>    <!--  jdbc驱动包 -->    <dependency>      <groupId>mysql</groupId>      <artifactId>mysql-connector-java</artifactId>      <version>5.1.30</version>    </dependency>    <!-- 添加阿里巴巴连接池Druid支持 -->    <dependency>      <groupId>com.alibaba</groupId>      <artifactId>druid</artifactId>      <version>1.0.16</version>    </dependency>    <!-- 添加log4j日志 -->    <dependency>      <groupId>log4j</groupId>      <artifactId>log4j</artifactId>      <version>1.2.17</version>    </dependency>    <dependency>      <groupId>org.slf4j</groupId>      <artifactId>slf4j-api</artifactId>      <version>1.7.21</version>    </dependency>    <!-- apache共公包 -->     <dependency>      <groupId>commons-logging</groupId>      <artifactId>commons-logging</artifactId>      <version>1.2</version>    </dependency>    <!-- 添加junit支持 -->    <dependency>      <groupId>junit</groupId>      <artifactId>junit</artifactId>      <version>4.12</version>      <scope>test</scope>    </dependency>

2.2spring与mybatis整合

2.2.1 新建mybatis-conf.xml文件

这个文件主要配置mybatis全局配置文件
例如别名驼峰命名自动转换等在这里我暂时只配置别名

<?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>    <!-- 别名 -->    <typeAliases>        <package name="ssm.blog.entity"/>    </typeAliases></configuration>

2.2.2新建spring-beans.xml文件

整合主要步骤

开启包扫描
配置druid数据源
列表内容
配置sqlSessionFactory
开启mybatis dao接口扫描
具体配置注解讲的很清楚

<?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">    <!-- 开启包扫描-->    <context:component-scan base-package="ssm.blog"/>    <!-- 配置druid数据源 -->    <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource">        <property name="username" value="root"/>        <property name="password" value="root"/>        <property name="driverClassName" value="com.mysql.jdbc.Driver"/>        <property name="url" value="jdbc:mysql://localhost:3306/db_blog"/>    </bean>    <!-- 配置mybatis的sqlSessionFactory -->    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">        <property name="dataSource" ref="dataSource"/>        <!-- 自动扫描mapper.xml文件-->        <property name="mapperLocations" value="classpath:mapper/*.xml"/>        <!-- 载入mybatis全局配置文件-->        <property name="configLocation" value="classpath:mybatis-conf.xml"/>    </bean>    <!-- 配置mybatis dao接口扫描-->    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">        <property name="basePackage" value="ssm.blog.dao"/>        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>    </bean>    <!-- 配置spring的声明式事务，名字为默认值 -->      <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">          <property name="dataSource" ref="dataSource" />      </bean>      <!-- 开启事务控制的注解支持 -->      <tx:annotation-driven transaction-manager="transactionManager"/> </beans>

现在mybatis与spring整合已经算完成了接下来我们测试一下

2.2.3测试spring与mybatis整合

1、表格结构
这里写图片描述
sql 文件

DROP DATABASE IF EXISTS db_blog;/*创建数据库，并设置编码*/CREATE DATABASE db_blog DEFAULT CHARACTER SET utf8;USE db_blog;CREATE TABLE `t_blogger` (  `id` INT(11) NOT NULL AUTO_INCREMENT COMMENT '博主id',  `username` VARCHAR(50) NOT NULL COMMENT '博主姓名',  `password` VARCHAR(100) NOT NULL COMMENT '博主密码',  `profile` TEXT COMMENT '博主信息',  `nickname` VARCHAR(50) DEFAULT NULL COMMENT '博主昵称',  `sign` VARCHAR(100) DEFAULT NULL COMMENT '博主签名',  `imagename` VARCHAR(100) DEFAULT NULL COMMENT '博主头像路径',  PRIMARY KEY (`id`)) ENGINE=INNODB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8;

2、实体类

package ssm.blog.entity;import org.springframework.stereotype.Component;import java.io.Serializable;/** * Created by xp on 2017/4/13. * @author xp * @Description 博主信息实体类 */@Component  //注册bean 为spring容器管理public class Blogger implements Serializable {    private Integer id;    private String userName;    //用户名    private String password;    //密码    private String profile;     //博主信息    private String nickName;    //昵称    private String sign;        //博主签名    private String imageName;   //图片路径    public Blogger(String userName, String password, String profile, String nickName, String sign, String imageName) {        this.userName = userName;        this.password = password;        this.profile = profile;        this.nickName = nickName;        this.sign = sign;        this.imageName = imageName;    }    public Blogger() {    }    public Integer getId() {        return id;    }    public void setId(Integer id) {        this.id = id;    }    public String getUserName() {        return userName;    }    public void setUserName(String userName) {        this.userName = userName;    }    public String getPassword() {        return password;    }    public void setPassword(String password) {        this.password = password;    }    public String getProfile() {        return profile;    }    public void setProfile(String profile) {        this.profile = profile;    }    public String getNickName() {        return nickName;    }    public void setNickName(String nickName) {        this.nickName = nickName;    }    public String getSign() {        return sign;    }    public void setSign(String sign) {        this.sign = sign;    }    public String getImageName() {        return imageName;    }    public void setImageName(String imageName) {        this.imageName = imageName;    }    @Override    public String toString() {        return "Blogger{" +                "id=" + id +                ", userName='" + userName + '\'' +                ", password='" + password + '\'' +                ", profile='" + profile + '\'' +                ", nickName='" + nickName + '\'' +                ", sign='" + sign + '\'' +                ", imageName='" + imageName + '\'' +                '}';    }}

3、dao接口以及mapper文件
dao接口

package ssm.blog.dao;import org.springframework.stereotype.Repository;import ssm.blog.entity.Blogger;/** * Created by xp on 2017/4/13. * 博主dao接口 */@Repository //注册为持久层的beanpublic interface BloggerDao {    /**     * 查询博主信息     * @return     */    Blogger getBloggerData();}

mapper

<?xml version="1.0" encoding="UTF-8" ?><!DOCTYPE mapper        PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"        "http://mybatis.org/dtd/mybatis-3-mapper.dtd"><mapper namespace="ssm.blog.dao.BloggerDao">    <!--        返回结果映射        如果开启驼峰命名转换且命名规范该段代码可以不写        因为配置别名 所以type属性使用的是mybatis-conf中的别名        -->    <resultMap type="Blogger" id="BloggerResult">        <id property="id" column="id"/>        <result property="userName" column="username"/>        <result property="password" column="password"/>        <result property="profile" column="profile"/>        <result property="nickName" column="nickname"/>        <result property="sign" column="sign"/>        <result property="imageName" column="imagename"/>    </resultMap>    <!--  定义字段集合 -->    <sql id="BloggerColumns">        id,username,password,profile,nickname,sign,imagename    </sql>    <!-- 接口中getBloggerData 具体实现-->    <select id="getBloggerData" resultMap="BloggerResult">            select <include refid="BloggerColumns"/>    from t_blogger where id = 1    </select></mapper>

4、log4j.properties 文件
创建log4j.properties 打印日志查看执行sql语句

log4j.rootLogger=DEBUG, Console  #Console  log4j.appender.Console=org.apache.log4j.ConsoleAppender  log4j.appender.Console.layout=org.apache.log4j.PatternLayout  log4j.appender.Console.layout.ConversionPattern=%d [%t] %-5p [%c] - %m%n  log4j.logger.java.sql.ResultSet=INFO  log4j.logger.org.apache=INFO  log4j.logger.java.sql.Connection=DEBUG  log4j.logger.java.sql.Statement=DEBUG  log4j.logger.java.sql.PreparedStatement=DEBUG

5、创建测试类并测试
BloggerDaoTest

package ssm.blog.dao;import org.junit.Test;import org.junit.runner.RunWith;import org.springframework.test.context.ContextConfiguration;import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;import ssm.blog.entity.Blogger;import javax.annotation.Resource;import static org.junit.Assert.*;/** * Created by xp on 2017/4/13. */@RunWith(SpringJUnit4ClassRunner.class) //使用spring测试@ContextConfiguration(locations = "classpath:spring-beans.xml") //设置spring配置文件路径public class BloggerDaoTest {    @Resource   //注入BloggerDao对象    private BloggerDao bloggerDao;    @Test    public void getBloggerData() throws Exception {        Blogger blogger = bloggerDao.getBloggerData();        System.out.println(blogger);    }}

打印结果
这里写图片描述
成功打印结果说明spring与mybatis整合成功。

2.3spring与springmvc整合

2.3.1创建spring-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: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/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd">    <!-- 扫描所有ssm.blog.controller包下面的所有controller -->    <context:component-scan base-package="ssm.blog.controller"/>    <!-- 开启注解配置-->    <mvc:annotation-driven/>    <!-- 静态资源解析，包括js,css,img... -->    <mvc:resources location="/static/" mapping="/static/**"/>    <!-- 配置视图解析器-->    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">        <!--视图前缀-->        <property name="prefix" value="/"/>        <!--视图后缀-->        <property name="suffix" value=".jsp"/>    </bean></beans>

2.3.2 配置web.xml文件

注释讲的很清楚我就不再讲了

<?xml version="1.0" encoding="UTF-8"?><web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"         xmlns="http://java.sun.com/xml/ns/javaee"         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee         http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"         id="WebApp_ID" version="3.0">    <!--spring配置文件路径-->    <context-param>        <param-name>contextConfigLocation</param-name>        <param-value>classpath:spring-beans.xml</param-value>    </context-param>    <!-- 配置spring监听器-->    <listener>        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>    </listener>    <!--spring mvc核心servlet-->    <servlet>        <servlet-name>dispatcherServlet</servlet-name>        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>        <!-- 初始化参数配置 springnvc配置文件路径-->        <init-param>            <param-name>contextConfigLocation</param-name>            <param-value>classpath:spring-mvc.xml</param-value>        </init-param>        <load-on-startup>1</load-on-startup>        <async-supported>true</async-supported>    </servlet>    <servlet-mapping>        <servlet-name>dispatcherServlet</servlet-name>        <url-pattern>*.do</url-pattern>    </servlet-mapping>    <servlet-mapping>        <servlet-name>dispatcherServlet</servlet-name>        <url-pattern>*.html</url-pattern>    </servlet-mapping>    <!-- 编码过滤器 -->    <filter>        <filter-name>encodingFilter</filter-name>        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>        <async-supported>true</async-supported>        <init-param>            <param-name>encoding</param-name>            <param-value>UTF-8</param-value>        </init-param>    </filter>    <filter-mapping>        <filter-name>encodingFilter</filter-name>        <url-pattern>/*</url-pattern>    </filter-mapping></web-app>

2.3.2测试

新建BloggerController

package ssm.blog.controller;import jdk.internal.org.objectweb.asm.tree.analysis.Value;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.ResponseBody;/** * Created by xp on 2017/4/13. * 博主控制器 */@Controller  //注册为控制器bean@RequestMapping(value = "/blog")    //请求路径public class BloggerController {    @ResponseBody  //返回json数据    @RequestMapping(value="/hello")    public String hello(){        return "hello";    }}
