1. 环境准备
开发环境确保安装了Java Development Kit (JDK)建议使用最新版本的Java。IDE推荐使用Eclipse, IntelliJ IDEA等支持Java开发的集成开发环境。数据库选择适合的数据库如MySQL, PostgreSQL等并准备好相应的驱动。构建工具可以使用Maven或Gradle来管理项目的依赖关系和构建过程。服务器Tomcat是常用的Servlet容器用于部署和运行Web应用程序。
2. 项目结构规划
创建一个新的Maven项目并设置好目录结构。通常的Maven项目结构如下
myProject
├── src
│ ├── main
│ │ ├── java
│ │ │ └── com.example
│ │ ├── resources
│ │ └── webapp
│ │ ├── WEB-INF
│ │ │ ├── views
│ │ │ ├── web.xml
│ │ │ └── spring-config.xml
│ │ └── index.jsp
│ └── test
│ └── java
│ └── com.example
└── pom.xml3. 配置文件
pom.xml在pom.xml中添加必要的依赖项例如Spring, MyBatis, MyBatis-Spring, 数据库驱动, Servlet API, JSTL等。web.xml配置Spring MVC的前端控制器DispatcherServlet以及字符编码过滤器等。spring-config.xml配置数据源、事务管理、MyBatis的SQLSessionFactoryBean等。applicationContext.xml如果需要可以分离出专门的应用上下文配置文件用于配置业务逻辑层和服务层的bean。mybatis-config.xml配置MyBatis的相关设置比如类型别名、映射器等。
4. 数据库设计
根据病人的治疗跟踪需求设计数据库表。可能需要的表包括但不限于
patients存储病人信息。treatments记录每个病人的治疗历史。doctors医生信息。appointments预约信息。medical_records医疗记录。medications药物信息。
确保为每个表定义主键并考虑外键约束以维护数据完整性。
5. 编写代码
DAO层编写接口和对应的Mapper XML文件用于与数据库交互。使用MyBatis进行查询、插入、更新和删除操作。Service层实现业务逻辑调用DAO层的方法完成对数据的操作。Controller层处理HTTP请求调用Service层提供的服务将结果返回给视图。View层使用JSP或其他模板引擎如Thymeleaf创建用户界面显示数据并接收用户的输入。
6. 测试
单元测试编写单元测试用例确保各个组件的功能正确无误。集成测试测试不同组件之间的协作是否正常。系统测试模拟真实场景下的操作验证整个系统的功能。
7. 部署
将项目打包成WAR文件并部署到Tomcat等Servlet容器上。配置好数据库连接和其他外部资源。启动服务器访问应用检查其是否正常工作。
8. 维护与优化
根据用户反馈和实际使用情况不断改进系统。优化性能提高响应速度。定期备份数据保证信息安全。
1. Maven依赖pom.xml
确保你的pom.xml中包含以下必要的依赖

/dependencies2. 数据库表设计
这里假设我们有一个简单的patients表
CREATE TABLE patients (id INT AUTO_INCREMENT PRIMARY KEY,name VARCHAR(100) NOT NULL,gender ENUM(M, F) NOT NULL,birth_date DATE NOT NULL,phone_number VARCHAR(20),address TEXT
);3. DAO层 (MyBatis Mapper)
创建一个PatientMapper接口和对应的XML映射文件。
PatientMapper.java:
package com.example.dao;import com.example.model.Patient;
import org.apache.ibatis.annotations.*;import java.util.List;Mapper
public interface PatientMapper {Select(SELECT * FROM patients WHERE id #{id})Patient selectById(Integer id);Insert(INSERT INTO patients(name, gender, birth_date, phone_number, address) VALUES(#{name}, #{gender}, #{birthDate}, #{phoneNumber}, #{address}))Options(useGeneratedKeys true, keyProperty id)void insert(Patient patient);Update(UPDATE patients SET name#{name}, gender#{gender}, birth_date#{birthDate}, phone_number#{phoneNumber}, address#{address} WHERE id#{id})void update(Patient patient);Delete(DELETE FROM patients WHERE id#{id})void deleteById(Integer id);Select(SELECT * FROM patients)ListPatient selectAll();
}PatientMapper.xml:
?xml version1.0 encodingUTF-8 ?
!DOCTYPE mapperPUBLIC -//mybatis.org//DTD Mapper 3.0//ENhttp://mybatis.org/dtd/mybatis-3-mapper.dtdmapper namespacecom.example.dao.PatientMapper!-- SQL statements here --
/mapper4. Service层
PatientService.java:
package com.example.service;import com.example.dao.PatientMapper;
import com.example.model.Patient;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;import java.util.List;Service
public class PatientService {Autowiredprivate PatientMapper patientMapper;public Patient getPatientById(Integer id) {return patientMapper.selectById(id);}public ListPatient getAllPatients() {return patientMapper.selectAll();}public void addPatient(Patient patient) {patientMapper.insert(patient);}public void updatePatient(Patient patient) {patientMapper.update(patient);}public void deletePatient(Integer id) {patientMapper.deleteById(id);}
}5. Controller层
PatientController.java:
package com.example.controller;import com.example.model.Patient;
import com.example.service.PatientService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.*;import java.util.List;Controller
RequestMapping(/patients)
public class PatientController {Autowiredprivate PatientService patientService;GetMappingpublic String listPatients(Model model) {ListPatient patients patientService.getAllPatients();model.addAttribute(patients, patients);return patientList;}GetMapping(/{id})public String viewPatient(PathVariable Integer id, Model model) {Patient patient patientService.getPatientById(id);model.addAttribute(patient, patient);return patientView;}PostMappingpublic String addPatient(ModelAttribute Patient patient) {patientService.addPatient(patient);return redirect:/patients;}PutMapping(/{id})public String updatePatient(PathVariable Integer id, ModelAttribute Patient patient) {patient.setId(id);patientService.updatePatient(patient);return redirect:/patients/ id;}DeleteMapping(/{id})public String deletePatient(PathVariable Integer id) {patientService.deletePatient(id);return redirect:/patients;}

/web-app7. 视图层 (JSP)
为了简单起见这里只给出一个patientList.jsp的例子
patientList.jsp:
% page languagejava contentTypetext/html; charsetUTF-8 pageEncodingUTF-8%
% taglib urihttp://java.sun.com/jsp/jstl/core prefixc %
!DOCTYPE html

/body
/html8. 启动项目
确保你的数据库已经启动并且根据applicationContext.xml中的配置正确设置了数据源连接信息。将项目部署到Tomcat服务器上启动服务器并访问应用。
以上代码只是一个简化版的例子实际项目中可能需要更多的功能和更复杂的逻辑比如用户认证、权限控制、日志记录等。
