項目需求：
使用 ： Spring+Mybatis+Spring-mvc 搭建項目 實現用戶的登錄
開發環境：
intellij idea：2019 + maven：3.5.4 + jdk：1.8
接下來直接開始流水線式教程
搭建不成功別着急 也別在一個問題上卡死 我為了學這個 應該練習了不少於20次，第一次的話 我覺得沒有一個人能一次成功！
Maven下載特別慢 直接翻到文章最下面 有解決方法
1、新建項目
2.配置搭建的基礎配置
3.一切選擇完了以后選擇 Next 進入項目名稱設置
4,配置項目名稱 等等 改成自己的項目名稱 也可以默認
項目新建完成了 開始配置項目的整體結構
這個是我項目的結構 搭建的時候可以參考下 如果哪里出問題了 記得看看結構是不是有問題 下面介紹下每個文件夾都是干嘛的
java - 存放項目源代碼的 - 包括 ： controller 控制層，mapper 接口層 我的 sql映射文件也放在這個里面了（這里不明白先不管往下走） ，pojo實體類，service業務邏輯層 這邊非常相似 最初版本的三層模式
resources - 存放項目配置文件的 ，后面文章的配置文件部分都是放在這里的
webapp - 建完項目自動會生成 （一般情況下 有些人就沒有 我曾經也沒有） 這個沒有的話百度 看看 實在不行的話應該是我的鍋 我的新建項目過程比較簡陋 看看別的博主的 應該能解決 這個里面 有個static的文件夾里面放的就是css ， js ， images 這些東西 jsp目錄就是jsp的內容 路徑這邊盡量就按照我的來 因為方便后面配置文件
前面基本上都是IDEA怎么新建Maven項目 介紹的不夠詳細 也可以去參考別的博客 下面直接開始干貨 （特別提醒：復制的時候記得把配置文件映射的路徑等等改成自己的項目路徑 不要無腦的亂來）
1.配置pom.xml 配置pom文件 copy的時候看着點 不要copy
下面這句話自己看着點 這個是防止xml文件不編譯的

2.新建 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:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.1.xsd"> <!-- 加載配置文件 *.properties --> <context:property-placeholder location="classpath:jdbc.properties"/> <!--配置數據庫 dataSource --> <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"> <!-- 加載數據庫用戶名 --> <property name="driverClass" value="${jdbc.driver}"/> <!-- 加載數據庫密碼 --> <property name="jdbcUrl" value="${jdbc.url}"/> <!-- 加載數據庫連接 --> <property name="user" value="${jdbc.username}"/> <!-- 加載數據庫驅動 --> <property name="password" value="${jdbc.password}"/> <!-- 最大並發連接數 --> <property name="maxPoolSize" value="30"/> <!-- 最小空閑連接數 --> <property name="minPoolSize" value="5"/> </bean> <!-- 配置sqlsessioFactory --> <bean id="sqlSessionFactoryBean" class="org.mybatis.spring.SqlSessionFactoryBean"> <!-- 配置數據源 引用（ref）dataSource（bean） --> <property name="dataSource" ref="dataSource"/> <!-- 加載mybatis 配置文件 --> <property name="configLocation" value="classpath:mybatis.xml"/> <property name="mapperLocations" value="classpath:com/hover/mapper/*Mapper.xml"/> </bean> <!-- 配置掃描包 加載mapper代理對象 --> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <!-- 掃描mapper路徑 --> <property name="basePackage" value="com.hover.mapper"/> <property name="sqlSessionFactoryBeanName" value="sqlSessionFactoryBean"/> </bean> <!-- 掃描Service包 --> <context:component-scan base-package="com.hover.service"/> </beans>
3.新建jdbc.properties配置文件 這個是數據庫的配置信息 記得里面的東西改成跟你相關的
jdbc.driver=com.mysql.jdbc.Driver #數據庫地址 jdbc.url=jdbc:mysql://localhost:3306/24-hourobserver?useUnicode=true&characterEncoding=utf8 #用戶名 jdbc.username=root #密碼 jdbc.password=1234
4.新建mybatis.xml配置文件
<?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> <!-- 開啟二級緩存 --> <settings> <!--<setting name="cacheEnabled" value="true"/>--> <!-- 是否開啟二級緩存 默認為true --> <setting name="cacheEnabled" value="true"/> <!-- 是否懶加載 --> <setting name="lazyLoadingEnabled" value="true" /> </settings> <typeAliases> <!--批量配置別名--> <package name="com.hover.pojo"/> </typeAliases> </configuration>
新建 spring-mvc.xml 配置文件
<?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:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:mvc="http://www.springframework.org/schema/mvc" xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.3.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.3.xsd"> <!--1.注解掃描位置--> <context:component-scan base-package="com.hover.controller"/> <mvc:resources location="/static/" mapping="/static/**"></mvc:resources> <mvc:annotation-driven > <!-- 消息轉換器 --> <mvc:message-converters register-defaults="true"> <bean class="org.springframework.http.converter.StringHttpMessageConverter"> <property name="supportedMediaTypes" value="text/plain;charset=UTF-8"/> </bean> </mvc:message-converters> </mvc:annotation-driven> <!--2.配置映射處理和適配器--> <bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter"/> <bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping"/> <!--3.視圖的解析器--> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/WEB-INF/jsp/"/> <property name="suffix" value=".jsp"/> </bean> </beans>
配置Web.xml配置文件
<!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 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_3_1.xsd" version="3.1"> <display-name>Archetype Created Web Application</display-name> <!-- 配置SprongIoC容器加載的配置文件 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicationContext.xml</param-value> </context-param> <context-param> <param-name>log4jRefreshInterval</param-name> <param-value>6000</param-value> </context-param> <!-- 用於初始化SpringIoC容器 --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <listener> <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class> </listener> <servlet> <servlet-name>DispatcherServlet</servlet-name> <!-- 核心控制器 --> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring-mvc.xml</param-value> </init-param> <!-- 應用啟動時,加載servlet --> <load-on-startup>1</load-on-startup> <multipart-config> <location>e:/upimgs</location> <max-file-size>5242880</max-file-size> <max-request-size>10485760</max-request-size> <file-size-threshold>0</file-size-threshold> </multipart-config> </servlet> <servlet-mapping> <!-- 約定優於配置，Spring MVC框架默認加載/WEB-INF/<servlet-name/>開頭-servlet.xml作為配置文件載入web工程中--> <servlet-name>DispatcherServlet</servlet-name> <!-- 攔截配置 --> <url-pattern>/</url-pattern> </servlet-mapping> <welcome-file-list> <welcome-file>/WEB-INF/jsp/login.jsp</welcome-file> </welcome-file-list> <!--亂碼過濾器--> <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> <init-param> <param-name>forceEncoding</param-name> <param-value>true</param-value> </init-param> </filter> <filter-mapping> <filter-name>characterEncodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> </web-app>
=====================都完了以后配置文件基本上就完事了========================
開始具體的功能部分
1.新建實體類 建在 java-包名-pojo里面 我里面的東西這個請不要照搬 跟着你的數據庫來
package com.hover.pojo; import java.util.Date; /** * 用戶表 * @author Yang * */ public class Users { private Integer u_id; //用戶編號 private Integer r_id; //角色編號 private String u_mobilephone; //手機號 private String u_password; //密碼 private Date u_createDate; //注冊時間 private String u_weiboaccount; //微信賬號 private String u_qqaccount; //QQ賬號 private String u_weChataccount; //微博賬號 private Integer u_delete; //物理是否被刪除 private Userinformation userInfo; //用戶詳細信息 //無參構造 public Users() { super(); // TODO Auto-generated constructor stub } //全參構造 public Users(Integer u_id, Integer r_id, String u_mobilephone, String u_password, Date u_createDate, String u_weiboaccount, String u_qqaccount, String u_weChataccount, Integer u_delete) { super(); this.u_id = u_id; this.r_id = r_id; this.u_mobilephone = u_mobilephone; this.u_password = u_password; this.u_createDate = u_createDate; this.u_weiboaccount = u_weiboaccount; this.u_qqaccount = u_qqaccount; this.u_weChataccount = u_weChataccount; this.u_delete = u_delete; } //get set public Integer getU_id() { return u_id; } public void setU_id(Integer u_id) { this.u_id = u_id; } public Integer getR_id() { return r_id; } public void setR_id(Integer r_id) { this.r_id = r_id; } public String getU_mobilephone() { return u_mobilephone; } public void setU_mobilephone(String u_mobilephone) { this.u_mobilephone = u_mobilephone; } public String getU_password() { return u_password; } public void setU_password(String u_password) { this.u_password = u_password; } public Date getU_createDate() { return u_createDate; } public void setU_createDate(Date u_createDate) { this.u_createDate = u_createDate; } public String getU_weiboaccount() { return u_weiboaccount; } public void setU_weiboaccount(String u_weiboaccount) { this.u_weiboaccount = u_weiboaccount; } public String getU_qqaccount() { return u_qqaccount; } public void setU_qqaccount(String u_qqaccount) { this.u_qqaccount = u_qqaccount; } public String getU_weChataccount() { return u_weChataccount; } public void setU_weChataccount(String u_weChataccount) { this.u_weChataccount = u_weChataccount; } public Integer getU_delete() { return u_delete; } public void setU_delete(Integer u_delete) { this.u_delete = u_delete; } public Userinformation getUserInfo() { return userInfo; } public void setUserInfo(Userinformation userInfo) { this.userInfo = userInfo; } public Users(Integer u_id, Integer r_id, String u_mobilephone, String u_password, Date u_createDate, String u_weiboaccount, String u_qqaccount, String u_weChataccount, Integer u_delete, Userinformation userInfo) { super(); this.u_id = u_id; this.r_id = r_id; this.u_mobilephone = u_mobilephone; this.u_password = u_password; this.u_createDate = u_createDate; this.u_weiboaccount = u_weiboaccount; this.u_qqaccount = u_qqaccount; this.u_weChataccount = u_weChataccount; this.u_delete = u_delete; this.userInfo = userInfo; } }
2.新建 mapper的接口 可以看到 前面說的 我的映射文件 和 dao放一個包里面了 名字也一樣 方便管理
2.1 先看 UserMapper.java 這個 Mapper 也就是曾經的DAO接口
package com.hover.mapper; import org.apache.ibatis.annotations.Param; public interface UserMapper { /** * 用戶登錄的方法 * @return */ public Integer userLogin(@Param("userCode")String userCode,@Param("password")String password); }
2.2下面是 UserMapper.xml 這個是Mapper的映射文件 （這邊強調一下 所有的命名都是 XXXMapper.xml）因為配置文件掃描的時候 我的規則是*Mapper.xml 你們也可改動 新手的話不要改了 （eg:我也是看着別的博主的博客學習 才會的 也是新手）
代碼里面的 <mapper namespace="com.hover.mapper.UserMapper"> 這句話當中的 namespace記得改成你的 這個相當於命名空間是唯一的 規范:包名+*Mapper的名字
<?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.hover.mapper.UserMapper"> <select id="userLogin" resultType="java.lang.Integer"> SELECT COUNT(1) FROM users WHERE u_mobilePhone=#{userCode} AND u_password=#{password} AND r_id<=3 </select> </mapper>
3.下面來看UserService.java
package com.hover.service; import org.apache.ibatis.annotations.Param; import org.springframework.stereotype.Service; @Service public interface UserService { /** * 用戶登錄的方法 * @return */ public Integer userLogin(@Param("userCode")String userCode, @Param("password")String password); }
4.接下來是 UserServiceImpl.java 也就是 Service層的實現 這邊 有用到注解
package com.hover.service.impl; import com.hover.mapper.UserMapper; import com.hover.service.UserService; import org.springframework.stereotype.Service; import javax.annotation.Resource; @Service public class UserServiceImpl implements UserService { @Resource private UserMapper userMapper; @Override public Integer userLogin(String userCode,String password) { return userMapper.userLogin(userCode,password); } }
5.下面就是最后一步了 UserController.java 控制層 如果是用Servlet的話 他應該跟Servlet作用差不多吧 我的理解 大佬勿噴 最后那個return "login" 是返回login.jsp 配置文件配置了 視圖解析器 所以說不用返回login.jsp 直接 login就行了
package com.hover.controller; import com.hover.service.UserService; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestParam; import javax.annotation.Resource; import javax.servlet.http.HttpServletRequest; @Controller @RequestMapping("/userController") public class UserController { @Resource private UserService userService; @RequestMapping("userLogin") public String userLogin(@RequestParam("userCode")String userCode, @RequestParam("password")String password, HttpServletRequest request){ Integer result=userService.userLogin(userCode,password); System.out.println("用戶的用戶名:"+userCode); System.out.println("用戶的密碼:"+password); if (result>0){ System.out.println("登錄成功!"); return "index"; }else{ System.out.println("登錄失敗!"); request.setAttribute("error","賬號或者密碼輸入錯誤"); } return "login"; } }
下面來看看 login.jsp的代碼
<%-- Created by IntelliJ IDEA.

OK了基本上 就通了 其中好多地方都沒說明白 有什么問題在QQ聯系：1336486608 這個項目有點其他問題 暫時不能大家共享 有什么問題直接聯系我
前面基本上完成了項目搭建 這邊 有個Maven的配置 可以看看 使用阿里的倉庫下載jar包快 需要改一下 conf-settings.xml 配置文件 切換成 阿里的倉庫 你要是翻牆 什么的 那默認用國外的也行 具體Maven下載是個什么 自行百度
我那個下載地址在 E：maven 根據自己的 改就行

Profiles can also be activated by JDK version prefix, where a | value of '1.4' might activate a profile when the build is executed on a JDK version of '1.4.2_07'. | Finally, the list of active profiles can be specified directly from the command line. | | NOTE: For profiles defined in the settings.xml, you are restricted to specifying only artifact | repositories, plugin repositories, and free-form properties to be used as configuration | variables for plugins in the POM. | |--> <profiles> <!-- profile | Specifies a set of introductions to the build process, to be activated using one or more of the | mechanisms described above. For inheritance purposes, and to activate profiles via <activatedProfiles/> | or the command line, profiles have to have an ID that is unique. | | An encouraged best practice for profile identification is to use a consistent naming convention | for profiles, such as 'env-dev', 'env-test', 'env-production', 'user-jdcasey', 'user-brett', etc. | This will make it more intuitive to understand what the set of introduced profiles is attempting | to accomplish, particularly when you only have a list of profile id's for debug. | | This profile example uses the JDK version to trigger activation, and provides a JDK-specific repo. <profile> <id>jdk-1.4</id> <activation> <jdk>1.4</jdk> </activation> <repositories> <repository> <id>jdk14</id> <name>Repository for JDK 1.4 builds</name> <url>http://www.myhost.com/maven/jdk14</url> <layout>default</layout> <snapshotPolicy>always</snapshotPolicy> </repository> </repositories> </profile> --> <!-- | Here is another profile, activated by the system property 'target-env' with a value of 'dev', | which provides a specific path to the Tomcat instance. To use this, your plugin configuration | might hypothetically look like: | | ... | <plugin> | <groupId>org.myco.myplugins</groupId> | <artifactId>myplugin</artifactId> | | <configuration> | <tomcatLocation>${tomcatPath}</tomcatLocation> | </configuration> | </plugin> | ... | | NOTE: If you just wanted to inject this configuration whenever someone set 'target-env' to | anything, you could just leave off the <value/> inside the activation-property. | <profile> <id>env-dev</id> <activation> <property> <name>target-env</name> <value>dev</value> </property> </activation> <properties> <tomcatPath>/path/to/tomcat/instance</tomcatPath> </properties> </profile> --> </profiles> <!-- activeProfiles | List of profiles that are active for all builds. | <activeProfiles> <activeProfile>alwaysActiveProfile</activeProfile> <activeProfile>anotherAlwaysActiveProfile</activeProfile> </activeProfiles> --> </settings>
