二.测试环境 1.创建项目目录 1.创建一个Maven项目。
2.在main目录中创建java目录
com.inspur.bean
com.inspur.controller
com.inspur.mapper
com.inspur.service
3.在resourses下创建
applicationContext.xml
dp.properties
mybatis-config.xml
springMVC.xml
log4j.properties
/mappers目录（如果不使用注解的话）
4.在webapp目录下创建以下目录
/css目录
/js目录
/images目录
/pages目录
2.配置文件 1.修改pom.xml文件，导入下列依赖。

3.测试环境 1.在bean目录下创建User类
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 package com.inspur.bean;import lombok.AllArgsConstructor;import lombok.Data;import lombok.NoArgsConstructor;@Data @NoArgsConstructor @AllArgsConstructor public class User { private Integer id; private String username; private String password; }
2.在mapper目录下创建UserMapper接口
1 2 3 4 5 6 7 8 9 10 11 12 package com.inspur.mapper;import com.inspur.bean.User;import org.apache.ibatis.annotations.Insert;import org.apache.ibatis.annotations.Mapper;@Mapper public interface UserMapper { @Insert("insert into user(username,password) values (#{username},#{password})") int save (User user) ; }
3.在service目录下创建UserService接口
1 2 3 4 5 6 7 8 package com.inspur.service;import com.inspur.bean.User;public interface UserService { public boolean save (User user) ; }
4.在service目录下创建impl目录并在该目录下创建UserServiceImpl类
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 package com.inspur.service.impl;import com.inspur.bean.User;import com.inspur.mapper.UserMapper;import com.inspur.service.UserService;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Service;import org.springframework.transaction.annotation.Transactional;@Service @Transactional public class UserServiceImpl implements UserService { @Autowired private UserMapper userMapper; @Override public boolean save (User user) { System.out.println(user); return userMapper.save(user)>0 ; } }
5.修改index.jsp文件，创建一个表单
1 2 3 4 5 6 7 8 9 10 11 12 13 <%@ page contentType="text/html;charset=UTF-8" language="java" isELIgnored="false" %> <html> <body> <h2>Hello World!</h2> <form action="${pageContext.request.contextPath}/user/save" method="post" > 用户名<input type="text" name="username" ><br> 密码<input type="password" name="password" ><br> <input type="submit" value="注册" > </form> </body> </html>
6.在webapp/pages目录下创建success.jsp
1 2 3 4 5 6 7 8 9 <%@ page contentType="text/html;charset=UTF-8" language="java" %> <html> <head> <title>Title</title> </head> <body> success </body> </html>
7.创建his数据库，并创建user表
1 2 3 4 5 6 create database hisCREATE TABLE user ( id int (11 ) , username varchar (30 ) , password varchar (30 ) ) DEFAULT CHARSET= utf8;
8.运行项目，插入数据成功即可。
三.项目开发 登录功能 1.创建一个扩展类
1 2 3 4 5 6 7 8 9 10 11 12 13 14 @Data @AllArgsConstructor @NoArgsConstructor public class QueryExtends { private String id; private String name; private String password; private String role; }
创建一个mapper,查看是哪种用户并获取它的id,name,role
1 2 3 4 5 6 7 8 9 @Mapper public interface QueryExtendsMapper { @Select(" SELECT id, username, role, password FROM users WHERE username=#{name} AND PASSWORD =#{password} " + " UNION " + " SELECT id, name, role, password FROM member WHERE name=#{name} AND PASSWORD =#{password} " + " UNION " + " SELECT id, name, role, password FROM doctor WHERE name=#{name} AND PASSWORD =#{password} ") QueryExtends login (@Param(value = "name") String name, @Param(value = "password") String password) ; }
service层创建接口与实现类
1 2 3 4 public interface QueryExtendsService { QueryExtends login (String name,String password) ; }
1 2 3 4 5 6 7 8 9 10 @Service @Transactional public class QueryExtendsServiceImpl implements QueryExtendsService { @Autowired private QueryExtendsMapper queryExtendsMapper; @Override public QueryExtends login (String name, String password) { return queryExtendsMapper.login(name,password); } }

创建过滤器
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 public class LoginCheckFilter implements Filter { @Override public void init (FilterConfig filterConfig) throws ServletException { } @Override public void doFilter (ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException { HttpServletRequest request= (HttpServletRequest) servletRequest; HttpSession session= request.getSession(); Object users = session.getAttribute("users" ); if (users!= null ){ filterChain.doFilter(servletRequest,servletResponse); }else { String requestURI = request.getRequestURI(); if (requestURI.contains("login" )){ filterChain.doFilter(servletRequest,servletResponse); }else { request.getRequestDispatcher("/pages/login.jsp" ).forward(servletRequest,servletResponse); } } } }
在web.xml中配置过滤器
1 2 3 4 5 6 7 8 <filter > <filter-name > loginFilter</filter-name > <filter-class > com.inspur.filter.LoginCheckFilter</filter-class > </filter > <filter-mapping > <filter-name > loginFilter</filter-name > <url-pattern > /pages/*</url-pattern > </filter-mapping >
增删改查功能 以增删改查会员为例
创建实体类
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 @Data public class Member { private String id; private String name; private String password; private String role; private String realname; private String credit; private String sex; private Integer age; private String tel; private Integer balance; private String anaphylaxis; private String createTime; }
创建mapper
注解方式
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 @Mapper public interface MemberMapper { @Insert("insert into member (id, name, password, role, realname, credit, sex, age, tel, balance, anaphylaxis, create_time) values (#{id}, #{name}, #{password}, #{role}, #{realname}, #{credit}, #{sex}, #{age}, #{tel}, #{balance}, #{anaphylaxis}, #{createTime})") int save (Member members) ; @Update("update member set name = #{name}, credit = #{credit}, tel = #{tel}, balance = #{balance} where id = #{id}") int update (Member members) ; List<Member> findMemberByCondition (Member member) ; @Delete("delete from member where id = #{id}") boolean deleteByMemberId (String id) ; @Select("select * from member where id = #{id}") Member findMemberById (String id) ; @Update("update member set password=#{password} where id = #{id}") void updatePassword (@Param(value = "id") String id, @Param(value = "password") String password) ; }
映射文件方式
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 <?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.inspur.mapper.MemberMapper" > <select id ="findMemberByCondition" resultType ="com.inspur.entity.Member" > select * from member <where > <if test ="id!=null and id!=''" > and id= #{id} </if > <if test ="name!=null and name!=''" > and name like '%${name}%' </if > <if test ="credit!=null and credit!=''" > and credit like '%${credit}%' </if > <if test ="tel!=null and tel!=''" > and tel like '%${tel}%' </if > </where > </select > </mapper >
业务层创建接口与实现类
1 2 3 4 5 6 7 8 9 10 11 12 13 public interface MemberService { boolean saveOrUpdateMember (Member member) ; PageInfo<Member> getMemberByCondition (Member member, Integer pageNum, Integer pageSize) ; boolean deleteByMemberId (String id) ; Member findMemberById (String id) ; List<Member> getAllMember () ; void updatePassword (String id, String password) ; }

其他关键技术 前端开启el表达式与c标签库
1 2 <%@ page contentType="text/html;charset=UTF-8" language="java" isELIgnored="false" %> <%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
使用for-each遍历集合,其中pageInfo.list 为固定写法
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 <c:forEach items="${pageInfo.list}" var ="doctorAdvice" > <tr> <td>${doctorAdvice.id}</td> <td>${doctorAdvice.memberId}</td> <td> <c:forEach items="${doctorList}" var ="doctor" > <c:if test="${doctor.id == doctorAdvice.doctorId}" >${doctor.name}</c:if > </c:forEach> </td> <td>${doctorAdvice.createTime}</td> <td>${doctorAdvice.prescription}</td> <%-- <td>西药治疗：皮炎平</td>--%> <td><a onclick="deletes(${doctorAdvice.id})" ><img src="../images/icon/del.png" width="16" height="16" /></a></td> <td><a onclick="ky(${doctorAdvice.registerOrderId}, ${doctorAdvice.id})" ><img src="../images/icon/edit2.png" width="16" height="16" /></a></td> </tr> </c:forEach>
c-if进行页面选择
1 2 3 4 5 6 7 8 <c:if test="${sessionScope.users.role==2}" > <ul> <li><a href="${pageContext.request.contextPath}/prescribe/sendList" target="right" >药品发放</a></li> <li><a href="${pageContext.request.contextPath}/registerorder/list" target="right" >挂号管理</a></li> <li><a href="${pageContext.request.contextPath}/doctorduty/list" target="right" >医生值班管理</a></li> <li><a href="${pageContext.request.contextPath}/doctorAdvice/list" target="right" >医生诊断管理</a></li> </ul> </c:if >
for-each加c-if进行判断选中
1 2 3 <c:forEach items="${doctorList}" var ="doctor" > <c:if test="${payment.userId == doctor.id}" >${doctor.name}</c:if > </c:forEach>
导航栏效果
