一、员工管理系统项目说明：

该项目主要是完成Spring+SpringMVC+mybatis的完整整合，功能实现比较单一，就是一个完成增删改查的小项目！

源代码在githee仓库：SSM实战项目：人事管理系统（蓝色版）

1、整个项目实现功能

管理员的登录，注册，员工的增删改查，批量删除，整个系统设计的目标人群是管理者，系统的主要功能是对员工进行各种信息的操作。主要是完成对数据库的增删改查的功能。

2、开发环境

3、数据库表设计

-- 创建员工表create table t_emp(id int primary key auto_increment,name varchar(20) not null,salary double not null,age int not null)-- 添加员工数据insert into t_emp values(null,"王恒杰",20000,21);insert into t_emp values(null,"杨福君",9000,19);-- 查询员工数据select * from t_emp;-- 创建管理员表create table t_admin(  id    int  primary key auto_increment, username varchar(20), password varchar(50))-- 添加数据insert into t_admin values(null,"王恒杰","123456");-- 查询select * from t_admin

4、Maven导入项目所依赖的jar包

          <dependency>            <groupId>junitgroupId>            <artifactId>junitartifactId>            <version>4.11version>            <scope>testscope>        dependency>        <dependency>            <groupId>org.springframeworkgroupId>            <artifactId>spring-coreartifactId>            <version>4.3.2.RELEASEversion>        dependency>        <dependency>            <groupId>org.springframeworkgroupId>            <artifactId>spring-contextartifactId>            <version>4.3.2.RELEASEversion>        dependency>        <dependency>            <groupId>org.springframeworkgroupId>            <artifactId>spring-context-supportartifactId>            <version>4.3.2.RELEASEversion>        dependency>        <dependency>            <groupId>org.springframeworkgroupId>            <artifactId>spring-jdbcartifactId>            <version>4.3.2.RELEASEversion>        dependency>        <dependency>            <groupId>org.springframeworkgroupId>            <artifactId>spring-aopartifactId>            <version>4.3.2.RELEASEversion>        dependency>        <dependency>            <groupId>org.springframeworkgroupId>            <artifactId>spring-beansartifactId>            <version>4.3.2.RELEASEversion>        dependency>        <dependency>            <groupId>org.springframeworkgroupId>            <artifactId>spring-expressionartifactId>            <version>4.3.2.RELEASEversion>        dependency>        <dependency>            <groupId>org.springframeworkgroupId>            <artifactId>spring-aspectsartifactId>            <version>4.3.2.RELEASEversion>        dependency>        <dependency>            <groupId>org.springframeworkgroupId>            <artifactId>spring-txartifactId>            <version>4.3.2.RELEASEversion>        dependency>        <dependency>            <groupId>org.springframeworkgroupId>            <artifactId>spring-webartifactId>            <version>4.3.2.RELEASEversion>        dependency>                <dependency>            <groupId>org.springframeworkgroupId>            <artifactId>spring-webmvcartifactId>            <version>4.3.2.RELEASEversion>        dependency>                <dependency>            <groupId>javax.servletgroupId>            <artifactId>servlet-apiartifactId>            <version>2.5version>            <scope>providedscope>        dependency>                <dependency>            <groupId>javax.servlet.jspgroupId>            <artifactId>jsp-apiartifactId>            <version>2.1version>        dependency>                <dependency>            <groupId>jstlgroupId>            <artifactId>jstlartifactId>            <version>1.2version>        dependency>                <dependency>            <groupId>mysqlgroupId>            <artifactId>mysql-connector-javaartifactId>            <version>8.0.16version>        dependency>                <dependency>            <groupId>org.mybatisgroupId>            <artifactId>mybatisartifactId>            <version>3.4.6version>        dependency>                <dependency>            <groupId>org.mybatisgroupId>            <artifactId>mybatis-springartifactId>            <version>1.3.1version>        dependency>

5、Spring+mybatis整合工厂（applicationContext.xml）

        <context:component-scan base-package="com.tjcu.whj">context:component-scan>          <context:property-placeholder location="classpath:jdbc.properties">context:property-placeholder>           <bean class="com.alibaba.druid.pool.DruidDataSource" name="dataSource">        <property name="driverClassName" value="${jdbc.driver}">property>        <property name="url" value="${jdbc.url}">property>        <property name="username" value="${jdbc.username}">property>        <property name="password" value="${jdbc.password}">property>    bean>        <bean class="org.mybatis.spring.SqlSessionFactoryBean" id="sqlSessionFactory">                <property name="dataSource" ref="dataSource">property>                <property name="mapperLocations" value="classpath:com/tjcu/mapper/*DaoMapper.xml">property>                <property name="typeAliasesPackage" value="com.tjcu.whj.entity">property>    bean>            <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">                <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory">property>                <property name="basePackage" value="com.tjcu.whj.dao">property>    bean>            <bean class="org.springframework.jdbc.datasource.DataSourceTransactionManager" id="transactionManager">        <property name="dataSource" ref="dataSource">property>    bean>            <tx:annotation-driven transaction-manager="transactionManager">tx:annotation-driven>

6、Spring+SpringMVC整合工厂（Spring-mvc.xml）

      <context:component-scan base-package="com.tjcu.whj">context:component-scan>        <mvc:annotation-driven/>        <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">                <property name="prefix" value="/">property>                <property name="suffix" value=".jsp">property>    bean>        <mvc:default-servlet-handler/>

二、管理员登录/注册模块功能开发

• 功能模块：登录，注册，注销，密码加密

• 注册示意图

• 登录示意图

1、dao层（adminDao.java）

public interface AdminDao {    /**     * 登录     * @param admin     * @return     */    public Admin login(Admin admin);    /**     *  注册     * @param admin     */    public void register(Admin admin);}

2、Service层

（1）adminService接口层

public interface AdminService {    /**     * 登录     * @param admin     * @return     */    public Admin login(Admin admin);    /**     *  注册     * @param admin     */    public void register(Admin admin);}

（2）adminServiceImpl实现类

@Service("adminService")@Transactionalpublic class AdminServiceImpl implements AdminService {    @Autowired  private AdminDao adminDao;    @Override    public Admin login(Admin admin) {        return adminDao.login(admin);    }    @Override    public void register(Admin admin) {         adminDao.register(admin);    }}

3、功能测试（adminTest）

public class AdminTest {    @Test    public void login(){        ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");        AdminService adminService = (AdminService) context.getBean("adminService");        Admin admin = new Admin(null,null, "王恒杰", "123456",true);        Admin login = adminService.login(admin);        System.out.println(login);    }    @Test    public void register(){        ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");        AdminService adminService = (AdminService) context.getBean("adminService");        Admin admin = new Admin(null, "风犬少年","邓正武", "234567",true);        adminService.register(admin);    }}

4、Controller层

@Controller("adminController")@RequestMapping("admin")public class AdminController {    /**     * 将adminService到AdminController中     */    @Autowired    private AdminService adminService;    /**     * 登录     * @param admin     * @return     */    @RequestMapping("login")    public String login(Admin admin,HttpServletRequest request){        String password = MD5Utils.md5(admin.getPassword());        admin.setPassword(password);        Admin admin1 = adminService.login(admin);        System.out.println(admin1);        if(admin1!=null){            request.getSession().setAttribute("admin",admin1);            return "redirect:/emp/show";        }       return "redirect:/login.jsp";    }    /**     *  注册     * @param admin     */    @RequestMapping("register")    public String register(Admin admin){        String password = MD5Utils.
            
                     

                 

                                                                                                                    
                         服务器托管

                                                                                               客户管理系统代码项目
                                                                                                           java代码蓝色字
