### ssm整合的简单案例（有源码） ###

*  一、先搭建整合环境
 *   *  1.使用maven创建一个web项目
     *  2.在pom.xml中导入相关坐标
     *  3.创建java文件夹与resource文件夹
 *  二、先把spring配置搭建完
 *   *  1.编写applicationContext.xml文件
     *  测试spring是否配置成功
 *  三、再使用spring整合springMVC框架
 *   *  1.编写web.xml,配置前端控制器 、解决中文乱码
     *  2.编写springmvc.xml文件，开启注解扫描，只扫描Controller注解、配置视图解析器、过滤静态资源
     *  3.测试springMVC是否搭好
     *  4.spring整合springMVC框架
 *  四、最后使用spring整合MyBatis框架
 *   *  1.编写MyBatis核心文件
     *  2.编写Dao接口
     *  3.测试MyBatis是否配置成功
     *  4.spring整合MyBatis框架
     *   *  1）applicationContext.xml 追加一下配置
         *  2）把Dao给spring管理
         *  测试整合

ssm框架的整合可以采用多种方式，这里选择xml + 注解的方式，整合的前提是每一个部分都要能自己独立运行，不然就没有意义了。

整合思路如下图：

## 2.在pom.xml中导入相关坐标 ##

如下：

## 3.创建java文件夹与resource文件夹 ##

![在这里插入图片描述][20200702221342241.png]

# 二、先把spring配置搭建完 #

## 1.编写applicationContext.xml文件 ##

值得一提的是，spring只处理业务层与持久层的注释，所以编写扫描时，要把表现层controller排除

applicationContext.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:aop="http://www.springframework.org/schema/aop" 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/aop http://www.springframework.org/schema/aop/spring-aop.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd">
    
        
        <context:component-scan base-package="ssm.test">
            
            <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
        </context:component-scan>
    </beans>

## 测试spring是否配置成功 ##

service的实现类

package ssm.test.service.impl;
    
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.stereotype.Service;
    import ssm.test.dao.AccountDao;
    import ssm.test.domain.Account;
    import ssm.test.service.AccountService;
    
    import java.util.List;
    
    
    @Service("accountService")
    public class AccountServiceImpl implements AccountService { 
    
        @Autowired
        private AccountDao accountDao;
    
        public List<Account> findAll() { 
            System.out.println("业务层：查询所有。。。");
            return accountDao.findAll();
        }
    
    
        public void saveAccount(Account account) { 
            System.out.println("业务层：保存用户。。，");
            accountDao.saveAccount(account);
        }
    
        @Override
        public void Delete(Integer id) { 
            System.out.println("业务层：删除账户。。。");
            accountDao.Delete(id);
        }
    }

测试类：

package ssm.test.test;
    
    import org.junit.Test;
    import org.springframework.context.ApplicationContext;
    import org.springframework.context.support.ClassPathXmlApplicationContext;
    import ssm.test.service.AccountService;
    
    public class testSpring { 
        @Test
        public void run1(){ 
            //加载配置文件
            ApplicationContext ac = new ClassPathXmlApplicationContext("classpath:applicationContext.xml");
            //获取对象
            AccountService as = (AccountService) ac.getBean("accountService");
            //调用方法
            as.findAll();
        }
    }

结果：  
![在这里插入图片描述][20200702222906322.png]  
说明spring框架可以使用，测试通过

# 三、再使用spring整合springMVC框架 #

## 1.编写web.xml,配置前端控制器 、解决中文乱码 ##

web.xml

<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd" >
    
    <web-app>
      <display-name>Archetype Created Web Application</display-name>
    
      
      <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:springmvc.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>
    
      
      <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>
      </filter>
      <filter-mapping>
        <filter-name>characterEncodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
      </filter-mapping>
    </web-app>

## 2.编写springmvc.xml文件，开启注解扫描，只扫描Controller注解、配置视图解析器、过滤静态资源 ##

springmvc.xml

<?xml version="1.0" encoding="UTF-8"?>
    <beans xmlns="http://www.springframework.org/schema/beans" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd ">
    
        
        <context:component-scan base-package="ssm.test">
            <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
        </context:component-scan>
    
        
        <bean id="internalResourceViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
            <property name="prefix" value="/WEB-INF/pages/"/>
            <property name="suffix" value=".jsp"/>
        </bean>
    
    
        
        <mvc:resources mapping="/css/**" location="/css/"/>
        <mvc:resources mapping="/images/**" location="/images/"/>
        <mvc:resources mapping="/js/**" location="/js/"/>
    
        
        <mvc:annotation-driven/>
    </beans>

## 3.测试springMVC是否搭好 ##

由于内容和代码比较多，我就不写上去了，最下面有我整个案例的源码的链接，可以自行下载  
![在这里插入图片描述][20200702225132986.png]  
如图，spring环境搭好

## 4.spring整合springMVC框架 ##

思路：spring整合springMVC：启动Tomcat服务器的时候，需要加载spring的配置文件，来完成正常的依赖注入

具体实现，在web.xml中加入spring监听器

<listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
      </listener>
      
      <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:applicationContext.xml</param-value>
      </context-param>

测试：  
![在这里插入图片描述][20200702230113573.png]  
两个一起出现说明整合成功

# 四、最后使用spring整合MyBatis框架 #

## 1.编写MyBatis核心文件 ##

SqlMapConfig.xml

<?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>
        
    
    
        
        <typeAliases>
            
            <package name="ssm.test.domain"/>
        </typeAliases>
    
        
        <environments default="mysql">
            
            <environment id="mysql">
                
                <transactionManager type="JDBC"></transactionManager>
                
                <dataSource type="POOLED">
                    
                    <property name="driver" value="com.mysql.jdbc.Driver"></property>
                    <property name="url" value="jdbc:mysql://localhost:3306/ssm"></property>
                    <property name="username" value="root"></property>
                    <property name="password" value="root"></property>
                </dataSource>
            </environment>
        </environments>
        
        <mappers>
            
            
            <package name="ssm.test.dao"></package>
        </mappers>
    </configuration>

## 2.编写Dao接口 ##

关于数据库和实体类我没有给出，但是可以在最下面我在GitHub的源码下载整个案例

package ssm.test.dao;
    
    import org.apache.ibatis.annotations.Delete;
    import org.apache.ibatis.annotations.Insert;
    import org.apache.ibatis.annotations.Select;
    import org.springframework.stereotype.Repository;
    import ssm.test.domain.Account;
    
    import java.util.List;
    
    /* * 账户Dao接口 * */
    public interface AccountDao { 
    
        //查询所有
        @Select("select * from account")
        public List<Account> findAll();
    
        //保存账户
        @Insert("insert into account (name,money) values (#{name},#{money})")
        public  void  saveAccount(Account account);
    
        //删除账户
        @Delete("delete from account where id = #{id}")
        public void Delete(Integer id);
    
    }

## 3.测试MyBatis是否配置成功 ##

![在这里插入图片描述][20200702231920261.png]  
如图，测试成功

## 4.spring整合MyBatis框架 ##

### 1）applicationContext.xml 追加一下配置 ###

<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
            <property name="driverClass" value="com.mysql.jdbc.Driver"></property>
            <property name="jdbcUrl" value="jdbc:mysql://localhost:3306/ssm"></property>

### 2）把Dao给spring管理 ###

在接口那里加上@Repository

/* * 账户Dao接口 * */
    @Repository
    public interface AccountDao { 
    
        //查询所有
        @Select("select * from account")
        public List<Account> findAll();
    
        //保存账户
        @Insert("insert into account (name,money) values (#{name},#{money})")
        public  void  saveAccount(Account account);
    
        //删除账户
        @Delete("delete from account where id = #{id}")
        public void Delete(Integer id);
    
    }

### 测试整合 ###

业务层调用了持久层的接口，测试成功

最后，因为刚接触ssm，肯定有很多问题，希望大佬的指正。
