基于S2SH架构的J2EE课程设计实训项目——《社区医疗信息管理系统》——构建出项目的Hibernate框架的开发环境

1、杨教授大学堂 精心创作的优秀程序员 职业提升必读系列资料基于S2SH架构的J2EE课程设计实训项目社区医疗信息管理系统构建出项目的Hibernate框架的开发环境1.1.1 构建出项目的Hibernate框架的开发环境1、在项目中添加Hibernate的系统库（1）然后将下面的各个*.lib库文件（总共13文件）在Eclipse中导入放到Web应用的/WEB-INF/lib目录中。antlr-2.7.6.jar、cglib-2.2.jar、commons-collections-3.1.jar、commons-logging-1.0.4.jar (在Struts中已经包含有，可以不再需要它)、

2、 javassist-3.9.0.GA.jar、ehcache-1.2.3.jar hibernate3.jar、jta-1.1.jar、dom4j-1.6.1.jar和log4j-1.2.15.jar、slf4j-api-1.5.8.jar和slf4j-simple-1.5.8.jar和c3p0-0.9.1.jar。（2）最后为下面的状态2、在项目中添加hibernate.cfg.xml文件（1）创建出Hibernate框架的系统配置文件hibernate.cfg.xml（2）系统配置文件hibernate.cfg.xml的代码示例 org.hibernate.dialect.MySQLDi

3、alect com.mysql.jdbc.Driver jdbc:mysql:/192.168.0.20:3306/chimsdb root root true 3、在项目中添加工作人员的PO实体类（1）实体类名称为StaffInfoPO，程序包名称为com.px1987.sshchims.dao.po（2）添加相关的成员属性（名称与数据库库表中的字段名称保持一致性）private String staffID=null;private String staffName=null;private String staffPassWord=null;private int staffSex=0;

4、private int staffAge=0;private String staffBirth=null;private int department=0;/* * 职务 */private String duty;/* * 职称 */private String positional_titles;（3）为每个成员属性添加get/set方法（4）再添加equals和Hashcode方法（5）StaffInfoPO类最终的代码示例package com.px1987.sshchims.dao.po;public class StaffInfoPO private String staffID

5、=null;public int hashCode() final int prime = 31;int result = 1;result = prime * result + department;result = prime * result + (duty = null) ? 0 : duty.hashCode();result = prime* result+ (positional_titles = null) ? 0 : positional_titles.hashCode();result = prime * result + staffAge;result = prime *

6、 result+ (staffBirth = null) ? 0 : staffBirth.hashCode();result = prime * result + (staffID = null) ? 0 : staffID.hashCode();result = prime * result+ (staffName = null) ? 0 : staffName.hashCode();result = prime * result+ (staffPassWord = null) ? 0 : staffPassWord.hashCode();result = prime * result +

7、 staffSex;return result;public boolean equals(Object obj) if (this = obj)return true;if (obj = null)return false;if (getClass() != obj.getClass()return false;StaffInfoPO other = (StaffInfoPO) obj;if (department != other.department)return false;if (duty = null) if (other.duty != null)return false; el

8、se if (!duty.equals(other.duty)return false;if (positional_titles = null) if (other.positional_titles != null)return false; else if (!positional_titles.equals(other.positional_titles)return false;if (staffAge != other.staffAge)return false;if (staffBirth = null) if (other.staffBirth != null)return f

9、alse; else if (!staffBirth.equals(other.staffBirth)return false;if (staffID = null) if (other.staffID != null)return false; else if (!staffID.equals(other.staffID)return false;if (staffName = null) if (other.staffName != null)return false; else if (!staffName.equals(other.staffName)return false;if (

10、staffPassWord = null) if (other.staffPassWord != null)return false; else if (!staffPassWord.equals(other.staffPassWord)return false;if (staffSex != other.staffSex)return false;return true;public String getStaffID() return staffID;public void setStaffID(String staffID) this.staffID = staffID;public S

11、tring getStaffName() return staffName;public void setStaffName(String staffName) this.staffName = staffName;public String getStaffPassWord() return staffPassWord;public void setStaffPassWord(String staffPassWord) this.staffPassWord = staffPassWord;public int getStaffSex() return staffSex;public void

12、 setStaffSex(int staffSex) this.staffSex = staffSex;public int getStaffAge() return staffAge;public void setStaffAge(int staffAge) this.staffAge = staffAge;public String getStaffBirth() return staffBirth;public void setStaffBirth(String staffBirth) this.staffBirth = staffBirth;public int getDepartme

13、nt() return department;public void setDepartment(int department) this.department = department;public String getDuty() return duty;public void setDuty(String duty) this.duty = duty;public String getPositional_titles() return positional_titles;public void setPositional_titles(String positionalTitles) positional_titles = positionalTitles;private String staffName=null;private String staffPassWord=null;private int staffSex=0;private int staffAge=0;private String staffBirth=null;private int department=
