            <version>1.2</version>
        </dependency>
    </dependencies>

2、創建項目目錄結構

3、創建spring-mybatis.xml文件

<?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">

    <!-- 掃描service包下所有使用注解的類型 -->
    <context:component-scan base-package="com.forever.service"/>

    <!-- 配置數據庫相關參數properties的屬性：${url} -->
    <context:property-placeholder location="classpath:properties/jdbc.properties"/>

    <!-- 數據庫連接池 -->
    <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
        <property name="driverClassName" value="${jdbc.driver}"/>
        <property name="url" value="${jdbc.url}"/>
        <property name="username" value="${jdbc.username}"/>
        <property name="password" value="${jdbc.password}"/>
    </bean>

    <!-- 配置SqlSessionFactory對象 -->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <!-- 注入數據庫連接池 -->
        <property name="dataSource" ref="dataSource"/>
        <!-- 掃描model包 使用別名 -->
        <property name="typeAliasesPackage" value="com.forever.pojo"/>
        <!-- 掃描sql配置文件:mapper需要的xml文件 -->
        <property name="mapperLocations" value="classpath:mapper/*.xml"/>
    </bean>

    <!-- 配置掃描Dao接口包，動態實現Dao接口，注入到spring容器中 -->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <!-- 注入sqlSessionFactory -->
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
        <!-- 給出需要掃描Dao接口包 -->
        <property name="basePackage" value="com.forever.mapper"/>
    </bean>

    <!-- 配置事務管理器 -->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <!-- 注入數據庫連接池 -->
        <property name="dataSource" ref="dataSource"/>
    </bean>

    <!-- 配置基於注解的聲明式事務 -->
    <tx:annotation-driven transaction-manager="transactionManager"/>

</beans>

4、創建spring-mvc.xml文件

<?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-3.0.xsd">

    <!-- 掃描web相關的bean -->
    <context:component-scan base-package="com.forever.controller"/>

    <!-- 開啟SpringMVC注解模式 -->
    <mvc:annotation-driven/>

    <!-- 靜態資源默認servlet配置 -->
    <mvc:default-servlet-handler/>

    <!-- 配置jsp 顯示ViewResolver -->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>
        <property name="prefix" value="/WEB-INF/jsp/"/>
        <property name="suffix" value=".jsp"/>
    </bean>

</beans>

5、創建jdbc.properties

jdbc.driver=com.mysql.cj.jdbc.Driver
#url
jdbc.url=jdbc:mysql://localhost:3306/db_boot?useUnicode=true&characterEncoding=utf8
#賬號
jdbc.username=root
#密碼
jdbc.password=root

6、日志文件log4j2.xml

<?xml version="1.0" encoding="UTF-8"?>
<!-- 設置log4j2的自身log級別為warn -->
<!-- OFF > FATAL > ERROR > WARN > INFO > DEBUG > TRACE > ALL -->
<configuration status="WARN" monitorInterval="30">
    <appenders>
        <console name="Console" target="SYSTEM_OUT">
            <PatternLayout pattern="[%d{HH:mm:ss:SSS}] [%p] - %l - %m%n"/>
        </console>

        <RollingFile name="RollingFileInfo" fileName="${sys:catalina.home}/logs/info/info.log"
                     filePattern="${sys:user.home}/logs/$${date:yyyy-MM}/info-%d{yyyy-MM-dd}-%i.log">
            <!--控制台只輸出level及以上級別的信息（onMatch），其他的直接拒絕（onMismatch）-->
            <Filters>
                <ThresholdFilter level="INFO"/>
                <ThresholdFilter level="WARN" onMatch="DENY" onMismatch="NEUTRAL"/>
            </Filters>
            <PatternLayout pattern="[%d{HH:mm:ss:SSS}] [%p] - %l - %m%n"/>
            <Policies>
                <TimeBasedTriggeringPolicy/>
                <SizeBasedTriggeringPolicy size="50 MB"/>
            </Policies>
        </RollingFile>

        <RollingFile name="RollingFileWarn" fileName="${sys:catalina.home}/logs/warn/warn.log"
                     filePattern="${sys:user.home}/logs/$${date:yyyy-MM}/warn-%d{yyyy-MM-dd}-%i.log">
            <Filters>
                <ThresholdFilter level="WARN"/>
                <ThresholdFilter level="ERROR" onMatch="DENY" onMismatch="NEUTRAL"/>
            </Filters>
            <PatternLayout pattern="[%d{HH:mm:ss:SSS}] [%p] - %l - %m%n"/>
            <Policies>
                <TimeBasedTriggeringPolicy/>
                <SizeBasedTriggeringPolicy size="50 MB"/>
            </Policies>
        </RollingFile>

        <RollingFile name="RollingFileError" fileName="${sys:catalina.home}/logs/error/error.log"
                     filePattern="${sys:user.home}/logs/$${date:yyyy-MM}/error-%d{yyyy-MM-dd}-%i.log">
            <ThresholdFilter level="ERROR"/>
            <PatternLayout pattern="[%d{HH:mm:ss:SSS}] [%p] - %l - %m%n"/>
            <Policies>
                <TimeBasedTriggeringPolicy/>
                <SizeBasedTriggeringPolicy size="50 MB"/>
            </Policies>
        </RollingFile>

    </appenders>

    <loggers>
        <!--過濾掉spring和mybatis的一些無用的DEBUG信息-->
        <logger name="org.springframework" level="INFO"></logger>
        <logger name="org.mybatis" level="INFO"></logger>
        <root level="all">
            <appender-ref ref="Console"/>
            <appender-ref ref="RollingFileInfo"/>
            <appender-ref ref="RollingFileWarn"/>
            <appender-ref ref="RollingFileError"/>
        </root>
    </loggers>

</configuration>

7、web.xml配置如下

<?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">
    <!-- 編碼過濾器 -->
    <filter>
        <filter-name>encodingFilter</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>encodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
    <!-- spring-mvc -->
    <servlet>
        <servlet-name>SpringMVC</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <!-- 配置springMVC需要加載的配置文件-->
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>
                classpath:spring/spring-mvc.xml
                classpath:spring/spring-mybatis.xml
            </param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
        <async-supported>true</async-supported>
    </servlet>
    <servlet-mapping>
        <servlet-name>SpringMVC</servlet-name>
        <!-- 匹配所有請求，此處也可以配置成 *.do 形式 -->
        <url-pattern>/</url-pattern>
    </servlet-mapping>

    <!--log4j2-->
    <listener>
        <listener-class>org.apache.logging.log4j.web.Log4jServletContextListener</listener-class>
    </listener>
    <filter>
        <filter-name>log4jServletFilter</filter-name>
        <filter-class>org.apache.logging.log4j.web.Log4jServletFilter</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>log4jServletFilter</filter-name>
        <url-pattern>/*</url-pattern>
        <dispatcher>REQUEST</dispatcher>
        <dispatcher>FORWARD</dispatcher>
        <dispatcher>INCLUDE</dispatcher>
        <dispatcher>ERROR</dispatcher>
    </filter-mapping>

</web-app>

8、創建數據庫表 插入信息

CREATE TABLE `users` (
`id`  int(11) NOT NULL AUTO_INCREMENT COMMENT '用戶id' ,
`username`  varchar(50) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL COMMENT '賬號' ,
`password`  varchar(50) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL COMMENT '密碼' ,
PRIMARY KEY (`id`)
)
ENGINE=InnoDB
DEFAULT CHARACTER SET=utf8 COLLATE=utf8_general_ci
COMMENT='用戶表'
AUTO_INCREMENT=4
ROW_FORMAT=COMPACT
;

INSERT INTO `users` (`id`, `username`, `password`) VALUES ('1', 'root', 'root');

9、創建實體IUsers

package com.forever.pojo;

public class IUsers {
    private int id;
    private String username;
    private String password;

    @Override
    public String toString() {
        return "IUsers{" +
                "id=" + id +
                ", username='" + username + '\'' +
                ", password='" + password + '\'' +
                '}';
    }

    public int getId() {
        return id;
    }

    public void setId(int 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;
    }
}

10、創建 IUsersMapper

package com.forever.mapper;

import com.forever.pojo.IUsers;
import org.springframework.stereotype.Repository;

import java.util.List;

@Repository
public interface IUsersMapper {

    public List<IUsers> selectAll();
    public boolean selectOne(IUsers users);
}

11、創建 IUsersService

package com.forever.service;

import com.forever.pojo.IUsers;

import java.util.List;

public interface IUsersService {
    public List<IUsers> selectAll();

    public boolean selectOne(IUsers users);
}

12、創建 UsersServiceImpl

package com.forever.service.impl;

import com.forever.mapper.IUsersMapper;
import com.forever.pojo.IUsers;
import com.forever.service.IUsersService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

import java.util.List;

@Service
@Transactional
public class UsersServiceImpl implements IUsersService {

    @Autowired
    private IUsersMapper usersMapper;

    public List<IUsers> selectAll(){
        return usersMapper.selectAll();
    }

    public boolean selectOne(IUsers users) {
        return usersMapper.selectOne(users);
    }
}

13、創建IUsersMapper.xml

<?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">
<!-- 設置為IUserDao接口方法提供sql語句配置 -->
<mapper namespace="com.forever.mapper.IUsersMapper">
    <select id="selectAll" resultType="IUsers">
        SELECT * FROM users
    </select>
    <select id="selectOne" resultType="boolean" parameterType="IUsers">
        select count(1) from users where username=#{username} and password=#{password}
    </select>
</mapper>

14、創建UsersController

package com.forever.controller;

import com.forever.pojo.IUsers;
import com.forever.service.IUsersService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

import javax.servlet.http.HttpServletRequest;
import java.util.List;

@Controller
public class UsersController {

    @Autowired
    private IUsersService usersService;

    @RequestMapping("/selectList")
    public String selectAl(HttpServletRequest request,IUsers users){
        boolean dron=usersService.selectOne(users);
        if (dron){
            request.setAttribute("ulist",usersService.selectAll());
            return "index";
        }
        request.setAttribute("error","賬號或密碼錯誤");
        return "login";
    }
    @RequestMapping("/login")
    public String login(){
        return "login";
    }
}

 15、創建login.jsp和index.jsp

        login.jsp

16、測試運行

   

啟動成功   瀏覽器訪問 http://localhost:8080/login

     輸入賬號密碼 查詢成功

到此ssm實現登錄查詢整合完成
