SSH(Spring4+Struts2+Hibernate5整合)

首先准备jar包和配置文件搭建环境jar包和配置文件如图:

其分别在spring-framework-4.3.9.RELEASE-dist.zip和hibernate-release-5.2.10.Final.zip与struts-2.5.10.1-all.zip中获取

这里配置jar包的方法使用的是eclipse配置导入jar包这里可以参考我之前的文章里面有配置的具体步骤:

以下是我的目录结构如图:

代码如下:

Dept.java

package entity;public class Dept {private int id;private String name;public int getId() {return id;}public void setId(int id) {this.id = id;}public String getName() {return name;}public void setName(String name) {this.name = name;}}

Dept.hbm.xml

Employee.java

package entity;public class Employee {private int id;private String empName;private double salary;private Dept dept;public int getId() {return id;}public void setId(int id) {this.id = id;}public String getEmpName() {return empName;}public void setEmpName(String empName) {this.empName = empName;}public double getSalary() {return salary;}public void setSalary(double salary) {this.salary = salary;}public Dept getDept() {return dept;}public void setDept(Dept dept) {this.dept = dept;}}

Employee.hbm.xml

EmployeeDao.java

package dao;import java.io.Serializable;import org.hibernate.SessionFactory;import entity.Employee;public class EmployeeDao {// 注入sessionFactory对象private SessionFactory sessionFactory;public void setSessionFactory(SessionFactory sessionFactory) {this.sessionFactory = sessionFactory;}/** * 保存员工 *  * @param employee */public Employee findById(Serializable id) {return sessionFactory.getCurrentSession().get(Employee.class, id);}}

EmployeeService.java

package service;import java.io.Serializable;import dao.EmployeeDao;import entity.Employee;public class EmployeeService {private EmployeeDao employeeDao;public void setEmployeeDao(EmployeeDao employeeDao) {this.employeeDao = employeeDao;}public Employee findById(Serializable id) {Employee employee = employeeDao.findById(id);return employee;}}

EmployeeAction.java

package action;import java.util.Map;import com.opensymphony.xwork2.ActionContext;import com.opensymphony.xwork2.ActionSupport;import entity.Employee;import service.EmployeeService;@SuppressWarnings("serial")public class EmployeeAction extends ActionSupport {private EmployeeService employeeService;public void setEmployeeService(EmployeeService employeeService) {this.employeeService = employeeService;}@Overridepublic String execute() {int empId = 2;Employee employee = employeeService.findById(empId);@SuppressWarnings("unchecked")Map request = (Map) ActionContext.getContext().get("request");request.put("employee", employee);return "success";}}
