Spring MVC+Hibernate整合简单讲解

SpringMVC+Hibernate整合

 

bean对象主要代码如下所示：

public class Student implements Serializable {
 private int sid;
 private String sname;
 private String description;
}

 

dao层对象主要代码如下所示：

public class StudentDao extends HibernateDaoSupport implements IstudentDao {

 public void addStudent(Student stu) {
  this.getHibernateTemplate().save(stu);

 }

 public void deleteStudent(Serializable key) {
    Student stu = this.getHibernateTemplate().get(Student.class, key);
  if (stu != null) {
   this.getHibernateTemplate().delete(stu);
  }
 }

 public List<Student> getAll() {
   List<Student> list = this.getHibernateTemplate().find("from Student");
  return list;
 }

 public Student getByKey(Serializable key) {
    return this.getHibernateTemplate().get(Student.class, key);
 }

 public void update(Student stu) {
   this.getHibernateTemplate().update(stu);
 }

}

 

Service层主要代码如下所示：

public class StudentService {
 private IstudentDao studao;

 public IstudentDao getStudao() {
  return studao;
 }

 public void setStudao(IstudentDao studao) {
  this.studao = studao;
 }

 public void addStudent(Student stu) {
  studao.addStudent(stu);
 }

 public void deleteStudent(Serializable key) {
  studao.deleteStudent(key);
 }

 public List<Student> getAll() {
  List<Student> list = studao.getAll();
  return list;
 }

 public Student getByKey(Serializable key) {
  return studao.getByKey(key);
 }

 public void update(Student stu) {
  studao.update(stu);
 } 
}

 

Control层代码如下所示：

@org.springframework.stereotype.Controller
@RequestMapping("/student")
public class Controller {
 private StudentService stuService;

 public StudentService getStuService() {
  return stuService;
 }

 @Resource(name = "stuService")
 public void setStuService(StudentService stuService) {
  this.stuService = stuService;
 }

 // /student/save.action
 @RequestMapping("/save")
 public String saveStudent(Student stu, HttpServletRequest req,
   Map<String, Object> map) {
  System.out.println(stu);
  System.out.println(stuService);
  stuService.addStudent(stu);
  return "redirect:all.action";
 }

 @RequestMapping("/delete")
 public String deleteStudent(int sid) {
  System.out.println("deleteStudent" + sid);
  stuService.deleteStudent(sid);
  return "redirect:all.action";
 }

 @RequestMapping("/update")
 public String updateStudent(Student stu) {
  stuService.update(stu);
  return "redirect:all.action";
 }

 @RequestMapping("/key")
 public String getByKey(int sid, HttpServletRequest req) {
  Student stu = stuService.getByKey(sid);
  req.setAttribute("stu", stu);
  return "showStu";
 }

 @RequestMapping("/all")
 public String getAll(HttpServletRequest req) {
  List<Student> list = stuService.getAll();
  req.setAttribute("list", list);
  return "showAll";
 }

}

 

 web.xml配置文件中的主要配置代码

<!-- 防止session提前关闭处理 将Hibernate的Session生命延长，为了解决由于Hibernate延迟加载，Session过早关闭问题-->
 <filter>
  <filter-name>OpenSessionInViewFilter</filter-name>
  <filter-class>org.springframework.orm.hibernate3.support.OpenSessionInViewFilter</filter-class>
 </filter>

 <filter-mapping>
  <filter-name>OpenSessionInViewFilter</filter-name>
  <url-pattern>*.action</url-pattern>
 </filter-mapping>

 <servlet>
  <servlet-name>test</servlet-name>
  <!-- 负责加载springmvc的配置文件 -->
  <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

 </servlet>
 <servlet-mapping>
  <servlet-name>test</servlet-name>

 </welcome-file-list>

 

springmvc配置文件中的主要配置代码:test-servlet.xml
