SSH2框架实现添加源码

1、SSH2与SSH1之简要比较SSH框架的优势开发效率高适应客户的需求随机变化代码耦合度小，易于扩展和维护大量简少配置文件编写，甚至可以零配置更大程度解耦合，架构之间不再互相依赖struts不再依赖servlet通配符配置，简化配置SSH1框架的劣势繁琐的配置文件编写struts1.X Action线程安全，仅允许一个实例去处理所有请求forward过于繁琐对Servlet依赖过强注解使用（struts、spring、hibernate或JPA及JDK注解）struts2借鉴webwork的成功之处，兼容struts1，集合两者优点，更易于整合spring及hibernate框架。Web.xml

2、配置文件qhjmencodingFilterorg.springframework.web.filter.CharacterEncodingFilterencodingUTF-8forceEncodingtrueencodingFilter/*struts2org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilteractionPackages.actionstruts2/*contextConfigLocationclasspath:applicationContext*.xmlorg.springframewor

3、k.web.context.ContextLoaderListenerindex.htmlindex.htmindex.jspdefault.htmldefault.htmdefault.jspapplicationContext.xml配置文件org.hibernate.dialect.MySQLDialecttrue.entity将以上配置文件放到项目中，以下是我的ssh项目目录C.entity实体类C.daodao类C.bizbiz业务类C.actionAction类用到的jar包下面写.entity实体类可用myeclipse方向生成，package .entity;import ja

4、vax.persistence.Column;import javax.persistence.Entity;import javax.persistence.GeneratedValue;import static javax.persistence.GenerationType.IDENTITY;import javax.persistence.Id;import javax.persistence.Table;/* * Student entity. * * author MyEclipse Persistence Tools */EntityTable(name = student)p

5、ublic class Student implements java.io.Serializable / Fieldsprivate Integer studentid;private String studentpass;private String studentlogin;private String studentname;/ Constructors/* default constructor */public Student() /* full constructor */public Student(String studentpass, String studentlogin

6、, String studentname) this.studentpass = studentpass;this.studentlogin = studentlogin;this.studentname = studentname;IdColumn(name = studentid, unique = true, nullable = false)public Integer getStudentid() return this.studentid;public void setStudentid(Integer studentid) this.studentid = studentid;C

7、olumn(name = studentpass, nullable = false, length = 50)public String getStudentpass() return this.studentpass;public void setStudentpass(String studentpass) this.studentpass = studentpass;Column(name = studentlogin, nullable = false, length = 50)public String getStudentlogin() return this.studentlo

8、gin;public void setStudentlogin(String studentlogin) this.studentlogin = studentlogin;Column(name = studentname, nullable = false, length = 50)public String getStudentname() return this.studentname;public void setStudentname(String studentname) this.studentname = studentname;还没有我们的BaseDao呢.这里用简单的Bas

9、eDao，可以通用C.baopackage .dao;import java.io.Serializable;import java.util.List;import org.springframework.orm.hibernate3.support.HibernateDaoSupport;import org.springframework.stereotype.Repository;Repositorypublic class BaseDao extends HibernateDaoSupport /* * * param object */public void add(Object

10、object)Object object2=super.getHibernateTemplate();super.getHibernateTemplate().save(object);/* * * param z * param id */public void del(Class z,Serializable id)super.getHibernateTemplate().delete(super.getHibernateTemplate().get(z, id);/* * * param object */public void update(Object object)super.ge

11、tHibernateTemplate().update(object);/* * * param hql * return */public List findByHql(String hql)return super.getHibernateTemplate().find(hql);/* * * param z * param id * return */public Object findById(Class z,Serializable id)return super.getHibernateTemplate().get(z, id);这次开始实现biz类.biz注释中出现了中文乱码我这

12、里，不影响我们项目package .biz;import java.util.List;import org.springframework.stereotype.Service;import org.springframework.transaction.annotation.Transactional;import .dao.BaseDao;import .entity.Student;Servicepublic class StudentBiz BaseDao baseDao=null;public void setBaseDao(BaseDao baseDao) this.baseDa

13、o = baseDao;/* * * param student */Transactionalpublic void addStudent(Student student)baseDao.add(student);/* * * param id */Transactionalpublic void delStudent(long id)baseDao.del(Student.class, id);/* * * param student */Transactionalpublic void updStudent(Student student)baseDao.update(student);

14、/* * hql * param hql * return */Transactional(readOnly=true)public List findAll(String hql)List list=baseDao.findByHql(hql);return list;/* * id * param id * return */Transactional(readOnly=true)public Student findByid(long id)Student student=(Student)baseDao.findById(Student.class, id);return studen

15、t;C.action类package .action;import java.util.List;import org.apache.struts2.convention.annotation.Namespace;import org.apache.struts2.convention.annotation.ParentPackage;import org.apache.struts2.convention.annotation.Result;import org.apache.struts2.convention.annotation.Results;import org.springfra

16、mework.context.annotation.Scope;import org.springframework.stereotype.Controller;import .biz.StudentBiz;import .entity.Student;import com.opensymphony.xwork2.ActionSupport;ControllerScope(prototype)Namespace(/)ParentPackage(struts-default)Results(Result(name=view,location=/add.jsp),Result(name=succe

17、ss,location=/view.jsp)public class StudentAction extends ActionSupport private StudentBiz studentBiz=null;public void setStudentBiz(StudentBiz studentBiz) this.studentBiz = studentBiz;private List liststu;private long id;private Student student;public List getListstu() return liststu;public void setListstu(List liststu) this.liststu = liststu;public long getId() return id;public void setId(long id) this.id = id;public Student getStudent() return student;public void setStudent(Student student) this.student = stu
