四、数据库创建

use workingsystem;
-- #行政班级表
create table adminClass
(
    id         int primary key not null auto_increment comment '行政班级id',
    name       varchar(255)    not null comment '班级名称',
    teacher_id int             not null default 0 comment '所属教师id'
);

-- #教学班级表
create table teacherClass
(
    id         int primary key not null auto_increment comment '行政班级id',
    name       varchar(255)    not null comment '班级名称',
    teacher_id int             not null default 0 comment '所属教师id'
);

-- #学生表
create table student
(
    id               int primary key not null auto_increment comment '学生id',
    name             varchar(255)    not null default '' comment '学生姓名',
    card_id          long            not null comment '学生卡id',
    phone            varchar(15)     not null default 0 comment '手机号',
    password         varchar(255)    not null comment '账号密码',
    admin_class_id   int                      default 0 not null comment '所属行政班级id',
    teacher_class_id int                      default 0 not null comment '所属教学班级id'
);

-- #教师表
create table teacher
(
    id       int primary key not null auto_increment comment '教师id',
    card_id  long            not null comment '教师工号',
    name     varchar(255)    not null default '' comment '教师姓名',
    phone    varchar(15)     not null default 0 comment '手机号',
    password varchar(255)    not null comment '账号密码'
);


-- #家长表
create table patriarch
(
    id         int primary key not null auto_increment comment '家长id',
    name       varchar(255)    not null default '' comment '家长姓名',
    phone      varchar(15)     not null comment '手机号',
    password   varchar(255)    not null comment '账号密码',
    student_id int             not null comment '对应绑定的学生id'
);

create table work_record
(
    id          int primary key not null auto_increment comment '作业记录id',
    work_id     int             not null default 0 comment '作业id',
    student_id  int             not null default 0 comment '提交的学生id',
    submit_time datetime        not null comment '提交时间',
    end_time    datetime comment '截至时间',
    appendix    varchar(255) comment '附件地址',
    teacher_id  int                      default 0 not null comment '创建的教师的id'
);

create table work
(
    id               int primary key not null auto_increment comment '作业id',
    name             varchar(255)    not null comment '作业名称',
    description      longtext comment '作业描述',
    create_time      datetime comment '创建时间',
    end_time         datetime comment '截至时间',
    appendix         varchar(255) comment '附件地址',
    teacher_id       int comment '创建教师的id',
    admin_class_id   int default 0 comment '行政班级id',
    teacher_class_id int default 0 comment '教学班级的id'
);

五、SSM框架整合

1. 项目创建

项目才有idea进行开发，首先在idea中创建maven项目

2. 依赖添加

pom.xml

</project>

3. 配置web.xml文件

web.xml

<!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_4_0.xsd"
         version="4.0">

  <display-name>Archetype Created Web Application</display-name>

  <!-- 添加日志监听器 -->
  <context-param>
    <param-name>log4jConfigLocation</param-name>
    <param-value>classpath:log4j.properties</param-value>
  </context-param>




  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:spring/spring.xml</param-value>
  </context-param>


  <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>
  </filter>
  <filter-mapping>
    <filter-name>CharacterEncodingFilter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>

  <servlet>
    <servlet-name>mvc</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <!-- 局部参数：声明配置文件位置 -->
    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath:spring/spring-mvc.xml</param-value>
    </init-param>
    <!-- Servlet启动时刻：可选 -->
    <load-on-startup>1</load-on-startup>

  </servlet>
  <servlet-mapping>
    <servlet-name>mvc</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>


</web-app>

4. 配置日志输出

log4j.properties

log4j.rootLogger = debug, stdout

log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{MM-dd HH:mm:ss} [%X{traceId}] %-5p [%t] %c{2}:%L - %m%n

5. spring配置文件

spring.xml

<beans  xmlns="http://www.springframework.org/schema/beans"
        xmlns:context="http://www.springframework.org/schema/context"
        xmlns:mvc="http://www.springframework.org/schema/mvc"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        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
                            http://www.springframework.org/schema/context/spring-context.xsd
                            http://www.springframework.org/schema/aop
                            http://www.springframework.org/schema/aop/spring-aop.xsd
                            http://www.springframework.org/schema/mvc
                            http://www.springframework.org/schema/mvc/spring-mvc.xsd">

    <import resource="classpath:spring/dao.xml"/>
    <import resource="classpath:spring/spring-mvc.xml"/>

    <context:property-placeholder location="classpath:config/config.properties" />

    <context:component-scan base-package="org.gjs">
        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
        <context:exclude-filter type="annotation" expression="org.springframework.web.bind.annotation.RestController"/>
        <context:exclude-filter type="annotation" expression="org.springframework.web.bind.annotation.ControllerAdvice"/>
    </context:component-scan>

    <!-- 注册注解开发驱动 -->
    <mvc:annotation-driven>
        <mvc:message-converters register-defaults="true">
            <bean class="org.springframework.http.converter.StringHttpMessageConverter">

                        <property name="failOnEmptyBeans" value="false"/>
                    </bean>
                </property>
            </bean>
        </mvc:message-converters>
    </mvc:annotation-driven>


    <aop:aspectj-autoproxy />

</beans>

6. spring-mvc配置

spring-mvc.xml

<beans  xmlns="http://www.springframework.org/schema/beans"
        xmlns:context="http://www.springframework.org/schema/context"
        xmlns:mvc="http://www.springframework.org/schema/mvc"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        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.xsd">

    <!-- 自动扫描且只扫描@Controller -->
    <context:component-scan base-package="org.gjs" use-default-filters="false">
        <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
        <context:include-filter type="annotation" expression="org.springframework.web.bind.annotation.RestController"/>
        <context:include-filter type="annotation" expression="org.springframework.web.bind.annotation.ControllerAdvice"/>
    </context:component-scan>




    <mvc:interceptors>
        <mvc:interceptor>
            <mvc:mapping path="/**"/>
            <bean class="org.gjs.interceptor.LogInterceptor" />
        </mvc:interceptor>
    </mvc:interceptors>
    <mvc:interceptors>
        <mvc:interceptor>
            <mvc:mapping path="/**"/>
            <!--   配置三个登陆地址不进行鉴权      -->
            <mvc:exclude-mapping path="/admin/login"/>
            <mvc:exclude-mapping path="/teacher/login"/>
            <mvc:exclude-mapping path="/student/login"/>
            <bean class="org.gjs.interceptor.AuthInterceptor" />
        </mvc:interceptor>
    </mvc:interceptors>

</beans>

7.mybatis整合
