零件库管理信息系统设计--part03：管理员登录部分设计

时间：2019-08-23 20:12:48

兄弟们，我又回来啦！

上次我把表建完了。今天来点干货，我们用ssm框架来先简单实现一下管理员的登录功能。

在实现之前，我对user表（管理员表）做了些简单的修改，先来看看：

忽略哪些蓝色的马赛克和乱输的数据，这个表一共5个字段，useraccountnum为账号，其他的都应该能看出来是什么。当然这里还是要说一句，这不是最终的表结构，以后根据需求还会修改的。

那么表有了，开始创建一个动态网页项目，这里我用的eclipse,项目是导的包，包如下：

本来想用maven配置包的，但想到自己对maven用的不熟练，算了，下次用maven做。

建好目录，项目结构如下：

项目名是pls,取得是parts,Library,System三个单词的首字母。服务器用的tomcat9,我觉得挺好用的。比myeclipse自带的服务器不知道快到哪里去了。

首先来看web.xml,代码如下:

1 <?xml version="1.0" encoding="UTF-8"?> 2 <web-app xmlns:xsi="/2001/XMLSchema-instance" xmlns="/xml/ns/javaee" xsi:schemaLocation="/xml/ns/javaee /xml/ns/javaee/web-app_3_1.xsd" id="WebApp_ID" version="3.1"> 3 <display-name>pls</display-name> 4 <welcome-file-list> 5<welcome-file>login.html</welcome-file> 6<welcome-file>index.htm</welcome-file> 7<welcome-file>index.jsp</welcome-file> 8<welcome-file>default.html</welcome-file> 9<welcome-file>default.htm</welcome-file>10<welcome-file>default.jsp</welcome-file>11 </welcome-file-list>12 13 14<context-param>15 <param-name>contextConfigLocation</param-name>16 <param-value>/WEB-INF/classes/spring/applicationContext.xml,/WEB-INF/classes/spring/applicationContext-*.xml</param-value>17</context-param>18<listener>19 <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>20</listener> 21222324<filter>25 <filter-name>encodingFilter</filter-name>26 <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>27 <async-supported>true</async-supported>28 <init-param>29 <param-name>encoding</param-name>30 <param-value>UTF-8</param-value>31 </init-param>32</filter>33<filter-mapping>34 <filter-name>encodingFilter</filter-name>35 <url-pattern>/*</url-pattern>36</filter-mapping>373839<listener>40 <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>41</listener>424344<servlet>45 <servlet-name>SpringMVC</servlet-name>46 <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>47 <init-param>48 <param-name>contextConfigLocation</param-name>49 <param-value>/WEB-INF/classes/spring/springmvc.xml</param-value>50 </init-param>51 55</servlet>56<servlet-mapping>57 <servlet-name>SpringMVC</servlet-name> 58 <url-pattern>*.action</url-pattern>59</servlet-mapping>60<welcome-file-list>61 <welcome-file>/index.jsp</welcome-file>62</welcome-file-list>63 64 </web-app>

感觉没什么好说的，用处注释都写了，看下一项，config文件夹的目录结构：

一样一样来，先是applicationContext.xml:

1 <beans xmlns="/schema/beans" 2xmlns:xsi="/2001/XMLSchema-instance" xmlns:mvc="/schema/mvc" 3xmlns:context="/schema/context" 4xmlns:aop="/schema/aop" xmlns:tx="/schema/tx" 5xsi:schemaLocation="/schema/beans 6 /schema/beans/spring-beans-3.1.xsd 7 /schema/mvc 8 /schema/mvc/spring-mvc-3.1.xsd 9 /schema/context 10 /schema/context/spring-context-3.1.xsd 11 /schema/aop 12 /schema/aop/spring-aop-3.1.xsd 13 /schema/tx 14 /schema/tx/spring-tx-3.1.xsd ">15 161718<context:property-placeholder location="classpath:db.properties" />1920<bean id="dataSource" class="mons.dbcp.BasicDataSource"21 destroy-method="close">22 <property name="driverClassName" value="${jdbc.driver}" />23 <property name="url" value="${jdbc.url}" />24 <property name="username" value="${jdbc.username}" />25 <property name="password" value="${jdbc.password}" />26 27 <property name="maxActive" value="${jdbc.maxActive}" />28 <property name="maxIdle" value="${jdbc.maxIdle}" />29</bean>3031323336<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">37 38 <property name="dataSource" ref="dataSource"/>39</bean>404142<tx:advice id="txAdvice" transaction-manager="transactionManager">43 44 <tx:attributes>45 <tx:method name="save*" propagation="REQUIRED" />46 <tx:method name="insert*" propagation="REQUIRED"/>47 <tx:method name="update*" propagation="REQUIRED"/>48 <tx:method name="delete*" propagation="REQUIRED"/>49 <tx:method name="find*" propagation="SUPPORTS" read-only="true"/>50 <tx:method name="get*" propagation="SUPPORTS" read-only="true"/>51 <tx:method name="select*" propagation="SUPPORTS" read-only="true"/>52 </tx:attributes>53</tx:advice>545556<aop:config>57 <aop:advisor advice-ref="txAdvice"58pointcut="execution(* com.pls.service.imp.*.*(..))"/>59</aop:config>60 61 62 </beans>

然后是applicationContext-dao.xml:

1 <beans xmlns="/schema/beans" 2xmlns:xsi="/2001/XMLSchema-instance" xmlns:mvc="/schema/mvc" 3xmlns:context="/schema/context" 4xmlns:aop="/schema/aop" xmlns:tx="/schema/tx" 5xsi:schemaLocation="/schema/beans 6 /schema/beans/spring-beans-3.1.xsd 7 /schema/mvc 8 /schema/mvc/spring-mvc-3.1.xsd 9 /schema/context 10 /schema/context/spring-context-3.1.xsd 11 /schema/aop 12 /schema/aop/spring-aop-3.1.xsd 13 /schema/tx 14 /schema/tx/spring-tx-3.1.xsd ">15 16 17 <bean id="sqlSessionFactoryBean" class="org.mybatis.spring.SqlSessionFactoryBean">1819<property name="dataSource" ref="dataSource"/>2021<property name="configLocation" value="classpath:mybatis/SqlMapConfig.xml"/>22 </bean>23 24 25 29 30 31 32 35 41 42 46 <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">4748<property name="sqlSessionFactoryBeanName" value="sqlSessionFactoryBean"/>49 52<property name="basePackage" value="com.pls.mapper"/>53 </bean>54 55 56 </beans>

这是以前学的时候用的配置文件，改了改继续拿来用，所以有大量注释掉的代码（我舍不得删.）

applicationContext-service.xml:

这里我本来想用注解代替的，但不知怎么的注解没起作用，无法完成注入，有大神的话希望看到后面能为我指出原因。

springmvc-xml：

还有：sqlmapconfig.xml:

1 <?xml version="1.0" encoding="UTF-8" ?> 2 <!DOCTYPE configuration 3 PUBLIC "-////DTD Config 3.0//EN" 4 "/dtd/mybatis-3-config.dtd"> 5 <configuration> 6 7 8<typeAliases> 9 <package name="com.pls.po" />10</typeAliases>1112<mappers>13 14 15 16 17 18</mappers>19 </configuration>

为什么<mappers>内没有代码？回去看dao的xml。

这里共有八张表的接口和pojo，今天要涉及到的只有红圈的选中的部分。

这些mapper和pojo不全是自己写的，大部分还是利用mybatis的逆向工程生成的，生成的配置文件如下：

1 <?xml version="1.0" encoding="UTF-8"?> 2 <!DOCTYPE generatorConfiguration 3 PUBLIC "-////DTD MyBatis Generator Configuration 1.0//EN" 4 "/dtd/mybatis-generator-config_1_0.dtd"> 5 6 <generatorConfiguration> 7<context id="testTables" targetRuntime="MyBatis3"> 8 <commentGenerator> 9 10 <property name="suppressAllComments" value="true" />11 </commentGenerator>12 13 <jdbcConnection driverClass="com.mysql.jdbc.Driver"14 connectionURL="jdbc:mysql://localhost:3306/partslibrarysystem" userId="root"15 password="20">16 </jdbcConnection>17 22 23 25 <javaTypeResolver>26 <property name="forceBigDecimals" value="false" />27 </javaTypeResolver>28 29 3031 <javaModelGenerator targetPackage="com.pls.po"32 targetProject=".\src">33 34 35 36 <property name="enableSubPackages" value="false" />37 38 39 40 <property name="trimStrings" value="true" />41 </javaModelGenerator>42 43 44 <sqlMapGenerator targetPackage="com.pls.mapper" 45 targetProject=".\src">46 47 <property name="enableSubPackages" value="false" />48 </sqlMapGenerator>49 50 <javaClientGenerator type="XMLMAPPER"51 targetPackage="com.pls.mapper" 52 targetProject=".\src">53 54 <property name="enableSubPackages" value="false" />55 </javaClientGenerator>56 57 <table schema="" tableName="allsortparts"></table>58 <table schema="" tableName="user"></table>59 <table schema="" tableName="bearing"></table>60 <table schema="" tableName="coupling"></table>61 <table schema="" tableName="electromotor"></table>62 <table schema="" tableName="fastener"></table>63 <table schema="" tableName="flange"></table>64 <table schema="" tableName="sealing_element"></table>65 66 70</context>71 </generatorConfiguration>

还需要这个java类：

1 package gm; 2 3 4 import java.io.File; 5 import java.util.ArrayList; 6 import java.util.List; 7 8 import org.mybatis.generator.api.MyBatisGenerator; 9 import org.mybatis.generator.config.Configuration;10 import org.mybatis.generator.config.xml.ConfigurationParser;11 import org.mybatis.generator.internal.DefaultShellCallback;12 13 public class GeneratorSqlmap {14 15public void generator() throws Exception{16 17 List<String> warnings = new ArrayList<String>();18 boolean overwrite = true;19 //指定逆向工程配置文件。20 File configFile = new File("generatorConfig.xml"); 21 ConfigurationParser cp = new ConfigurationParser(warnings);22 Configuration config = cp.parseConfiguration(configFile);23 DefaultShellCallback callback = new DefaultShellCallback(overwrite);24 MyBatisGenerator myBatisGenerator = new MyBatisGenerator(config,25 callback, warnings);26 myBatisGenerator.generate(null);27 28} 29public static void main(String[] args) throws Exception {30 try {31 GeneratorSqlmap generatorSqlmap = new GeneratorSqlmap();32 generatorSqlmap.generator();33 } catch (Exception e) {34 e.printStackTrace();35 }36 37}38 39 }

运行这个文件，mapper和pojo就自动帮你生成了，是不是很方便。

看一看mapper.xml和dao接口吧：

1 package com.pls.mapper; 2 3 import com.pls.po.User; 4 import com.pls.po.UserExample; 5 import java.util.List; 6 import org.apache.ibatis.annotations.Param; 7 8 public interface UserMapper { 9int countByExample(UserExample example);10 11int deleteByExample(UserExample example);12 13int deleteByPrimaryKey(Integer iduser);14 15int insert(User record);16 17int insertSelective(User record);18 19List<User> selectByExample(UserExample example);20 21User selectByPrimaryKey(Integer iduser);22 23int updateByExampleSelective(@Param("record") User record, @Param("example") UserExample example);24 25int updateByExample(@Param("record") User record, @Param("example") UserExample example);26 27int updateByPrimaryKeySelective(User record);28 29int updateByPrimaryKey(User record);3031User selectByUseraccountnum(String useraccountnum);3233List<User> getAllUser();3435 }

user.java没什么好说的，但还是贴上来：

service接口就不看了，直接看实现类代码：

1 package com.pls.service.imp; 2 3 import java.util.List; 4 5 import javax.annotation.Resource; 6 7 import org.springframework.stereotype.Service; 8 9 import com.pls.mapper.UserMapper;10 import com.pls.po.User;11 import com.pls.po.UserExample;12 import com.pls.po.UserExample.Criteria;13 import com.pls.service.PlsService;14 15 @Service("plsService")16 public class PlsServiceImp implements PlsService {17 18@Resource19private UserMapper userDao;22@Override23public User getUserById(int iduser) {24 // TODO Auto-generated method stub25 return this.userDao.selectByPrimaryKey(iduser);26}2728@Override29public List<User> getAllUser() {30 // TODO Auto-generated method stub31 //List<User> list;32 3334 //UserExample e=new UserExample();35 36 List<User> list=this.userDao.getAllUser();37 38 return list;39}40 41//根据用户名查找用户，主要用于登录时验证密码42@Override43public User getUserByUseraccountnum(String useraccountnum){44 45 //UserExample example= new UserExample();46 //Criteria criteria=example.createCriteria();47 //criteria.andUseraccountnumEqualTo(useraccountnum);48 User user=this.userDao.selectByUseraccountnum(useraccountnum);49 50 51 52 return user;53}5455//删除方法56@Override57public void deleteUser(int iduser){58 this.userDao.deleteByPrimaryKey(iduser);59}6061//根据名字或账号查询方法62@Override63public List<User> findByNameOrAccountnum(String nameOrAccountnum){64 UserExample e1=new UserExample();65 Criteria c1=e1.createCriteria();66 c1.andUsernameLike("%"+nameOrAccountnum+"%");67 List<User> list=this.userDao.selectByExample(e1);68 UserExample e2=new UserExample();69 Criteria c2=e2.createCriteria();70 c2.andUseraccountnumLike("%"+nameOrAccountnum+"%");71 list.addAll(this.userDao.selectByExample(e2));72 return list;73}7475//插入的方法76@Override77public int insertUser(User user){78 79 int iduser=this.userDao.insert(user);80 81 return iduser;82}8384//更新用户85@Override86public int updateUser(User User){87 88 int iduser=this.userDao.updateByPrimaryKey(User);89 90 return iduser;91 92}93 }

控制层目录：

先看userController:

1 package com.pls.controller; 2 3 import javax.servlet.http.HttpServletRequest; 4 5 import org.springframework.context.ApplicationContext; 6 import org.springframework.context.support.ClassPathXmlApplicationContext; 7 import org.springframework.stereotype.Controller; 8 import org.springframework.ui.Model; 9 import org.springframework.web.bind.annotation.RequestMapping;10 11 import com.pls.po.User;12 import com.pls.service.PlsService;13 14 @Controller15 @RequestMapping("/log")16 public class UserController {17 18ApplicationContext ac = new ClassPathXmlApplicationContext(new String[] { "spring/applicationContext.xml",19 "spring/applicationContext-dao.xml", "spring/applicationContext-service.xml" });20PlsService plsService = (PlsService) ac.getBean("plsService");21 22//用于验证用户密码是否输入正确23@RequestMapping("/submit")24public String toIndex(HttpServletRequest request, Model model, String useraccountnum, String password) {25 26 27 User user = this.plsService.getUserByUseraccountnum(useraccountnum);28 if (user != null) {29 if (user.getUserpassword().equals(password)) {30 31 model.addAttribute("user", user);32 model.addAttribute("iduser", user.getIduser());33 return "index";34 35 } else {36 return "error";37 }38 } else {39 return "error";40 }41 42}43 44//跳转到登录页面45@RequestMapping("/login")46public String login(Model model) throws Exception {47 48 return "login";49}505152 }

本来想用注解直接注入service的，结果一直报空指针错误，注入不成功，没办法只好用导配置文件的方式，不知道哪位大神能给我指点一下，说一下那个地方出错了。

这里我就不按action一个一个给你们看jsp页面及实现效果了，现在已经快12点了，我待会儿集中放后面。

代码是糙了一点，不过因为是第一次做项目嘛，包容包容。

来看看最后效果：

这肯定不是最终版本，我还有一些功能及一些地方需要修改。前端的代码不是我自己写的，是从网上下载的免费模板，在此感谢源码之家提供的免费模板，有兴趣的小伙伴可以取下一个来玩。本人第一次做项目，发到博客来和大家探讨学习，希望那些大神嘴下留情，不喜勿喷。

我还会继续更新我的毕设的，感谢大家支持。
