SpringMVC + Spring + Hibernate
本文主要记录: 框架需要的配置文件的配置 + Dao层写法 + Service层写法 + Controller写法
spring的配置文件还有spring mvc的配置文件如下:

Controller层写法
- package cn.demo;
- import javax.annotation.Resource;
- import org.springframework.stereotype.Controller;
- import org.springframework.web.bind.annotation.RequestMapping;
- import org.springframework.web.servlet.ModelAndView;
- import cn.edu.fjnu.hubmis.model.personnel.Employee;
- /**
- *
- * Simple to Introduction
- *
- * @ProjectName: [HubMIS]
- * @Package: [cn.edu.fjnu.hubmis.web.controller]
- * @ClassName: [helloworldController]

- /* 还可以加入@RequestMapping (
- * 财务部:@RequestMapping(value = "/finance")
- * 人事部:@RequestMapping(value = "/personnel")
- * 其他的根据需要来定
- * )
- * @RequestMapping(value = "/monitor", method = RequestMethod.GET)
- * 表示此类接受 http://localhost:8080/monitor这类型的访问请求,请求的方式为Get请求,
- * 不写默认为两种请求方式都处理
- * */
- @Controller
- @RequestMapping(value = "/personnel")
- public class employeeController {
- /*你下面需要用到的ServiceImpl,由于之前已经把xxxxServiceImpl都写出来了,并通过了测试,所以直接用你之前注入的service就可以了
- * 如:
- * 我这里想完成一个员工的添加, 我要往helloworldController引入EmployeeServiceImpl对象,用IEmployeeService接口来定义它
- * 但名字为employeeServiceImpl(第一个字母小写)
- *
- *
- * */
- @Resource
- private IEmployeeService employeeServiceImpl;
- //请求URL到处理器功能处理方法的映射,如果类名写了映射的地址如/monitor,这里又写了/hello
- //那么当访问http://localhost:8080/monitor/hello时,就会调用这个方法
- //如果类名头没写,则访问http://localhost:8080/hello时,调用此方法
- @RequestMapping(value = "/hello")
- public ModelAndView hello() {
- /* jsp -> controller 传递的数据*/
- /*此处为传递过来的数据对象类(这个具体看你们开发的过程中需要哪些类,可以自己定义。)
- * 如:
- * (data) 一般会传递JSON格式,接受
- * Form -> javabean
- *
- * */

- /* Result -> return: jsp*/
- ModelAndView mv = new ModelAndView();

- // A项目的开发人员,你们可以放你们的Page,List<Page>或者单个javabean实体对象!
- mv.addObject("message", "ResultObject");
- // 设置逻辑视图名,视图解析器会根据该名字解析到具体的视图页面:
- //如这里,它会去找hello.jsp这个页面
- mv.setViewName("hello");
- return mv; //模型数据和逻辑视图名
- }
- /*
- * @RequestBody 将HTTP请求正文转换为适合的HttpMessageConverter对象。
- @ResponseBody 将内容或对象作为 HTTP 响应正文返回,并调用适合HttpMessageConverter的Adapter转换对象,写入输出流。
- * */
- /*

Service层写法
- package cn.demo;
- import javax.annotation.Resource;
- import org.springframework.stereotype.Service;
- import org.springframework.transaction.annotation.Transactional;
- import cn.edu.fjnu.hubmis.dao.personnel.IEmployeeDao;
- import cn.edu.fjnu.hubmis.model.personnel.Employee;
- /**
- *
- * Simple to Introduction
- *
- * @ProjectName: [HubMIS]
- * @Package: [cn.demo]
- * @ClassName: [EmployeeServiceImpl]
- * @Description: [描述该类的功能]
- * @Author: [逍遥梦]
- * @CreateDate: [2014-3-19 上午8:35:02]
- * @UpdateUser: [逍遥梦]
- * @UpdateDate: [2014-3-19 上午8:35:02]
- * @UpdateRemark: [说明本次修改内容]
- * @Version: [v1.0]
- *
- * Demo作用:大家来参考此XxxxxServiceImpl的写法
- *
- * 明白Service所处的位置:
- * Jsp -> Controller -> Service -> Dao -> hibernate -> DataBase
- * Result -> return: Service -> return: Controller -> return: Jsp
- *
- *
- * 现在会涉及到几个问题:
- * 1.springmvc中controller和jsp之间的几种传值(写到cn.demo.helloworldController中)
- * 2.
- * 即:
- * 如果Controller需要一个员工Employee, 这个JavaBean类已经存在,Controller将"表单"
- *
- */
- /*Service的实现类要加上 Transactional事务处理注解 和 service注解*/
- @Transactional
- @Service
- public class EmployeeServiceImpl implements IEmployeeService {
- /*注入dao对象*/
- @Resource
- private IEmployeeDao employeeDaoImpl;
- public void addEmployee(Employee employee){
- //增加一个员工
- employeeDaoImpl.addEmployee(employee);
- }
- }
Dao层写法
- package cn.edu.fjnu.hubmis.dao.personnel.impl;
- import javax.annotation.Resource;
- import org.springframework.stereotype.Repository;
- import cn.edu.fjnu.hubmis.dao.common.IGenericDao;
- import cn.edu.fjnu.hubmis.dao.personnel.IEmployeeDao;
- import cn.edu.fjnu.hubmis.model.personnel.Employee;
- import cn.edu.fjnu.hubmis.utils.Page;
- @Repository
- public class EmployeeDaoImpl implements IEmployeeDao{
- @Resource
- private IGenericDao genericDAO;
- public boolean addEmployee(Employee employee) {
- try {
- this.genericDAO.save(employee);
