一：导入所需要的依赖与处理静态资源导出问题：

<dependencies>
    <dependency>
        <groupId>junit</groupId>
        <artifactId>junit</artifactId>
        <version>4.12</version>

    </dependency>
    <dependency>
        <groupId>com.mchange</groupId>

        <version>2.5</version>
    </dependency>
    <dependency>
        <groupId>javax.servlet.jsp</groupId>
        <artifactId>jsp-api</artifactId>
        <version>2.2</version>
    </dependency>
    <dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>jstl</artifactId>
        <version>1.2</version>
    </dependency>
    <dependency>
        <groupId>org.mybatis</groupId>
        <artifactId>mybatis-spring</artifactId>
        <version>2.0.2</version>
    </dependency>
    <dependency>
        <groupId>org.mybatis</groupId>
        <artifactId>mybatis</artifactId>
        <version>3.5.2</version>
    </dependency>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-webmvc</artifactId>
        <version>5.1.9.RELEASE</version>
    </dependency>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-jdbc</artifactId>
        <version>5.1.9.RELEASE</version>
    </dependency>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-test</artifactId>
        <version>5.1.9.RELEASE</version>

    </dependency>
    <dependency>
        <groupId>jstl</groupId>
        <artifactId>jstl</artifactId>
        <version>1.2</version>
    </dependency>

    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-aspects</artifactId>
        <version>5.1.9.RELEASE</version>
    </dependency>
    
</dependencies>
<build>
    <resources>
        <resource>
            <directory>src/main/java</directory>
            <includes>
                <include>**/*.properties</include>
                <include>**/*.xml</include>
            </includes>
            <filtering>false</filtering>

                <include>**/*.properties</include>
                <include>**/*.xml</include>
            </includes>
            <filtering>false</filtering>
        </resource>
    </resources>
</build>

二：在resource目录下建立mybatis.xml（其实有没有这个无所谓，这个文件的目的只是看起来像整合了mybatis层，其中mybatis.xml中的跟数据库有关的操作都交给spring去接管）

<?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>
    <settings>
        <setting name="logImpl" value="STDOUT_LOGGING"/>
    </settings>
</configuration>

三：在resource目录下建立datebase.properties文件

jdbc.driverClass=com.mysql.jdbc.Driver
jdbc.jdbcurl=jdbc:mysql://localhost:3306/mybatis?useSSL=false&useUnicode=true&characterEncoding=UTF-8
jdbc.user=root
jdbc.password=ztb

四：在resource目录下建立spring-mapper.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 https://www.springframework.org/schema/context/spring-context.xsd">
    <!--    读取数据配置属性文件-->
    <context:property-placeholder location="classpath:db.properties"></context:property-placeholder>
    <!--    配置数据源-->
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">

        <property name="driverClass" value="${jdbc.driverClass}"></property>
        <property name="jdbcUrl" value="${jdbc.jdbcurl}"></property>
        <property name="user" value="${jdbc.user}"></property>
        <property name="password" value="${jdbc.password}"></property>
    </bean>
    <!--    配置sqlsessionfactorybean-->
    <bean  class="org.mybatis.spring.SqlSessionFactoryBean">
        <!--        关联数据源-->
        <property name="dataSource" ref="dataSource"></property>
        <!--绑定mybatis核心配置文件-->
        <property name="configLocation" value="classpath:mybatis-config.xml"></property>
        <!--    给实体类起别名-->
        <property name="typeAliasesPackage" value="com.ztb.pojo"></property>
    </bean>
    <!--  注册mapper.xml文件  -->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="com.ztb.mapper"></property>
    </bean>
</beans>

五：在resource目录下建立spring-service.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:aop="http://www.springframework.org/schema/aop"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context https://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/aop https://www.springframework.org/schema/aop/spring-aop.xsd">
<!--     要有mapper层的文件-->
    <import resource="spring-mapper.xml"></import>
    <!--添加包扫描-->
    <context:component-scan base-package="com.ztb.service"></context:component-scan>

 <!--下面这些是事务操作，但是加上事务会一直报错，不知道是什么原因-->

<!--&lt;!&ndash;    添加事务管理器&ndash;&gt;-->
<!--    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">-->
<!--&lt;!&ndash;        切记要配置数据源&ndash;&gt;-->
<!--        <property name="dataSource" ref="dataSource"></property>-->
<!--    </bean>-->


<!--    <tx:advice id="myadvice" transaction-manager="transactionManager">-->
<!--        <tx:attributes>-->
<!--            &lt;!&ndash;     *指的是为所有方法添加事务       REQUIRED指的是增删改，&ndash;&gt;-->
<!--            <tx:method name="*" propagation="NOT_SUPPORTED"/>-->

<!--        </tx:attributes>-->
<!--    </tx:advice>-->
<!--<aop:config>-->
<!--    <aop:pointcut id="mycut" expression="execution(* com.ztb.service.*.*(..))"/>-->
<!--&lt;!&ndash;    把myadvice的事务绑定到service的所有方法中&ndash;&gt;-->
<!--    <aop:advisor advice-ref="myadvice" pointcut-ref="mycut"></aop:advisor>-->
<!--</aop:config>-->
</beans>

六：在resource目录下建立spring-controller.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
        https://www.springframework.org/schema/context/spring-context.xsd
        http://www.springframework.org/schema/mvc
        https://www.springframework.org/schema/mvc/spring-mvc.xsd">
<!--    要有上一层servcie的文件-->
<import resource="spring-service.xml"></import>
    <!--添加包扫描-->
    <context:component-scan base-package="com.ztb.controller"/>
<!--    添加注解驱动-->
    <mvc:annotation-driven></mvc:annotation-driven>
<!--    如果是ajax请求,那么不需要配置视图解析器-->

<!--    如果不是ajax请求，则需要配置视图解析器-->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" id="internalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/jsp/"/>
        <property name="suffix" value=".jsp"/>
    </bean>
</beans>

上面这几个文件分别对应ssm三层架构的几个接口与类

七：在web.xml文件中注册spring和springmvc框架，以及字符编码过滤器

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"
         version="4.0">
<!--字符编码过滤问题-->
    <filter>
        <filter-name>character-filter</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>character-filter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

<!--    注册mvc框架-->
    <servlet>
        <servlet-name>springmvc</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:spring-controller.xml</param-value>
        </init-param>
    </servlet>
    <servlet-mapping>
        <servlet-name>springmvc</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>
<!--    注册spring框架,目的就是启动spring容器-->
    <listener>
        <listener-class>org.springframework.web.context.ContextCleanupListener</listener-class>
    </listener>
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:spring-*.xml</param-value>
    </context-param>
</web-app>

八：建立实体类包pojo，包中建立实体类

package com.ztb.pojo;

public class User {
    private Integer id;
    private String name;
    private String pwd;

    public User() {
    }

    public User(Integer id, String name, String pwd) {
        this.id = id;
        this.name = name;
        this.pwd = pwd;
    }

    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getPwd() {
        return pwd;
    }

    public void setPwd(String pwd) {
        this.pwd = pwd;
    }

    @Override
    public String toString() {
        return "User{" +
                "id=" + id +
                ", name='" + name + '\'' +
                ", pwd='" + pwd + '\'' +
                '}';
    }
}

九：建立mapper包，包中建立接口与对应的数据库的操作的xml文件，注意接口与xml文件的名字必须一致

接口：

package com.ztb.mapper;

import com.ztb.pojo.User;

import java.util.List;

public interface UserMapper {
    List<User> selectAll();

    int deleteid(Integer id);

    int insertuser(User user);

    int updateuser(User user);
}

xml文件：

<?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="com.ztb.mapper.UserMapper">
    <select id="selectAll" resultType="user">
        select  * from user
    </select>

    <delete id="deleteid" parameterType="int">
        delete from user where id=#{id}
    </delete>

    <insert id="insertuser" parameterType="user">
        insert into user (id,name,pwd) values (#{id},#{name},#{pwd})
    </insert>
    <update id="updateuser" parameterType="user">
        update user set pwd=#{pwd},name=#{name} where id=#{id}
    </update>
</mapper>

十：建立service包，包中建立接口与对应的类

接口：

public interface UserService {
    List<User> selectAll();

    int deleteid(Integer id);

    int insertuser(User user);
    int updateuser(User user);
}

实现类：

@Service
public class UserServiceImpl implements UserService {
    @Autowired
    UserMapper userMapper;
    public List<User> selectAll() {
        return userMapper.selectAll();
    }

    public int deleteid(Integer id) {
        return userMapper.deleteid(id);
    }

    public int insertuser(User user) {
        return userMapper.insertuser(user);
    }

    public int updateuser(User user) {
        return userMapper.updateuser(user);
    }
}

十一：进行测试，测试通过后在进行controller层

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {
        "classpath:spring-service.xml"})
public class ServiceTest {
    @Autowired
    UserService userService;
    @Test
    public void test1(){
        List<User> list = userService.selectAll();
        for (User user : list) {
            System.out.println(user);
        }
    }
    @Test
    public void test2(){
        int deleteid = userService.deleteid(16);
        System.out.println(deleteid);
    }

    @Test
    public void test3(){
        int deleteid = userService.insertuser(new User(14,"宋","www"));
        System.out.println(deleteid);
    }
}

十二：进行controller层的编写：

@Controller
public class UserController {
    @Autowired
    UserService userService;
    @RequestMapping("showuser")
    public String showuser(HttpServletRequest request){
        List<User> list = userService.selectAll();
        request.setAttribute("userlist",list);
        return "main";
    }

十三：配置tomcat，测试浏览器与服务器的交互

 

遇到的一些问题以及解决方法：

一：spring单元测试的依赖版本要和spring-*各个依赖的版本相同，否则会报错

二：添加包扫描时，要用<context:compoent-scan>，不能用<context:scan>，否则会报无法找到bean的错。

三：在spring-service.xml文件中一定要导入spring-mapper.xml，在在spring-controller.xml文件中一定要导入spring-service.xml，否则会报错

四：需要在web-inf目录下新建lib包，然后加入全部的外部依赖，步骤file-project settings-artifacts

五：就是事务的切面配置，只要配置事务切面，就会报错，不知道该怎么解决
