MyEclipse10+Struts2.1+Spring3.3+Hibernate3.3全注解框架搭建.docx

一、 新建web项目1. FileNewweb project2. 工程名称：king-back点选Java EE 6.0标准二、 添加ssh2支持1. 添加struts2工程上点右键myeclipseadd struts capabilites点选struts2.1url模式点选 /*添加struts2 core lib和struts2 spring lib新建LoginAction类package com.frank.action;import com.opensymphony.xwork2.ActionSupport;/* * author steve frank * */public class LoginAction extends ActionSupport private String name;private String password;public String getName() return name;public void setName(String name) = name;public String getPassword() return password;public void setPassword(String password) this.password = password;public String execute() if (name.equals(steve) & password.equals(123)return SUCCESS;elsereturn INPUT;修改struts.xml/success.jsp/fail.jsp 修改index.jspMy JSP index.jsp starting page 添加success.jspMy JSP success.jsp starting page$password添加fail.jspMy JSP fail.jsp starting page登录失败,用户名或密码错误.当前web.xml如下，直接启动会报spring监听错误，因为刚才已经添加了spring支持struts的lib包。添加spring监听，重新启动会提示找不到spring配置文件。2. 添加spring右键myeclipseadd spring capabilities勾选spring 3.0 aop lib,spring 3.0 core lib,spring 3.0 persistence core lib,spring 3.0 persistence jdbc lib,spring 3.0 web lib;点选copy checked library contents to project folder当前web.xml如下，重新启动tomcat，成功。打开浏览器，输入http:/localhost:8088/king-back,（tomcat端口未修改过的应该为8080），出现如下界面。直接点击submit，成功跳转到success.jsp，界面如下。如果修改用户名为frank,如下点击submit后跳转到fail.jsp如下3. 添加hibernate先配置好数据源驱动，如下右键myeclipseadd hibernate capabilities点选hibernate 3.3，勾选enable hibernate annotations support;勾选hibernate 3.3 annotations&entity manager,hibernate 3.3 core lib;点选copy checked library jars to project folder and add to build-path点选spring configuration file,交给spring配置数据源勾选existing spring configuration file选择配置好的数据源驱动 去掉create seesionfactory class的勾。然后点击完成。三、 数据反向生成1. 新建文件夹com.frank.model，准备放置生成的实体类和dao类2. 在项目中新建data.sql文件，内容如下，连接mysql的test库，新建表studentDROP TABLE IF EXISTS student;CREATE TABLE student ( id int(11) NOT NULL, name varchar(20) default NULL, role_id int(11) default NULL, PRIMARY KEY (id) ENGINE=InnoDB DEFAULT CHARSET=utf8;- - Records of student- -INSERT INTO student VALUES (1, 张三, 1);INSERT INTO student VALUES (2, 李四, 2);INSERT INTO student VALUES (3, 王五, 1);SELECT * FROM student;3. 生成Dao和实体类过程如下打开Test库，选择student表，右键hibernate reverse engineering出现如下视图，通过browse选择king-back项目和com.frank.model文件夹结果如下，勾选create pojo db table mapping information点选add hibernate mapping annotations to pojo保留update hibernate configuration with mapping resource location;去掉create abstract class勾；勾选java data access object(dao) 勾选generate precise findby methods点选spring daoId generator 选择native结果如下四、 编写测试1. 新建test类package test;import java.util.List;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;import com.frank.model.Student;import com.frank.model.StudentDAO;public class Test public static void main(String args) ApplicationContext context = new ClassPathXmlApplicationContext(applicationContext.xml);StudentDAO dao = (StudentDAO) context.getBean(StudentDAO);List list = dao.findAll();int n = list.size();for (int i = 0; i n; i+) Student c = list.get(i);String name = c.getName();System.out.println(name);运行结果如下，说明项目基本上是ok的。2. 修改action类public String execute() getData();if (name.equals(steve) & password.equals(123)return SUCCESS;elsereturn INPUT;private void getData() ApplicationContext context = new ClassPathXmlApplicationContext(applicationContext.xml);StudentDAO dao = (StudentDAO) context.getBean(StudentDAO);List list = dao.findAll();int n = list.size();for (int i = 0; i n; i+) Student c = list.get(i);String name = c.getName();System.out.println(name);刷新浏览器，查看控制台打印结果。五、 添加注解配置1. 修改struts.xml2. 修改LoginAction,在execute方法上添加Action(value = login, results = Result(name = INPUT, location = /index.jsp),Result(name = SUCCESS, location = /WEB-INF/content/success.jsp) )3. action注解完成,可以测试通过,接下来添加service注解等4. 修改applicationContext.xmlorg.hibernate.dialect.MySQLDialectcom.frank.model.Student5. Service、dao 的接口和实现类StudentService.javapublic interface StudentService /* * 根据主键查询Student * param id * return */public Student findById(Integer id);StudentServiceImpl.javaServicepublic class StudentServiceImpl implements StudentService Resourceprivate StudentDAO studentDAO;Overridepublic Student findById(Integer id) / TODO Auto-generated method stubreturn studentDAO.findById(id);StudentDAO.javapublic interface StudentDAOpublic abstract void save(Student transientInstance);public abstract void delete(Student persistentInstance);public abstract Student findById(java.lang.Integer id);public abstract List findByExample(Student instance);public abstract List findByProperty(String propertyName, Object value);public abstract List findByName(Object name);public abstract List findAll();public abstract Student merge(Student detachedInstance);public abstract void attachDirty(Student instance);public abstract void attachClean(Student instance);StudentDAOImpl.javaRepositorypublic class StudentDAOImpl extends HibernateDaoSupport implements StudentDAO private static final Logger log = LoggerFactory.getLogger(StudentDAOImpl.class);/ property constantspublic static final String NAME = name;private SessionFactory sessionFacotry;Resourcepublic void setSessionFacotry(SessionFactory sessionFacotry) super.setSessionFactory(sessionFacotry);protected void initDao() / do nothing/* * (non-Javadoc) * * see com.frank.dao.impl.S#save(com.frank.model.Student) */Overridepublic void save(Student transientInstance) log.debug(saving Student instance);try getHibernateTemplate().save(transientInstance);log.debug(save successful); catch (RuntimeException re) log.error(save failed, re);throw re;/* * (non-Javadoc) * * see com.frank.dao.impl.S#delete(com.frank.model.Student) */Overridepublic void delete(Student persistentInstance) log.debug(deleting Student instance);try getHibernateTemplate().delete(persistentInstance);log.debug(delete successful); catch (RuntimeException re) log.error(delete failed, re);throw re;/* * (non-Javadoc) * * see com.frank.dao.impl.S#findById(java.lang.Integer) */Overridepublic Student findById(java.lang.Integer id) log.debug(getting Student instance with id: + id);try Student instance = (Student) getHibernateTemplate().get(com.frank.model.Student, id);return instance; catch (RuntimeException re) log.error(get failed, re);throw re;/* * (non-Javadoc) * * see com.frank.dao.impl.S#findByExample(com.frank.model.Student) */Overridepublic List findByExample(Student instance) log.debug(finding Student instance by example);try List results = (List) getHibernateTemplate().findByExample(instance);log.debug(find by example successful, result size: + results.size();return results; catch (RuntimeException re) log.error(find by example failed, re);throw re;/* * (non-Javadoc) * * see com.frank.dao.impl.S#findByProperty(java.lang.String, * java.lang.Object) */Overridepublic List findByProperty(String propertyName, Object value) log.debug(finding Student instance with property: + propertyName+ , value: + value);try String queryString = from Student as model where model.+ propertyName + = ?;return getHibernateTemplate().find(queryString, value); catch (RuntimeException re) log.error(find by property name failed, re);throw re;/* * (non-Javadoc) * * see com.frank.dao.impl.S#findByName(java.lang.Object) */Overridepublic List findByName(Object name) return findByProperty(NAME, name);/* * (non-Javadoc) * * see com.frank.dao.impl.S#findAll() */Overridepublic List findAll() log.debug(finding all Student instances);try String queryString = from Student;return getHibernateTemplate().find(queryString); catch (RuntimeException re) log.error(find all failed, re);throw re;/* * (non-Javadoc) * * see com.frank.dao.impl.S#merge(com.frank.model.Student) */Overridepublic Student merge(Student detachedInstance) log.debug(merging Student instance);try Student result = (Student) getHibernateTemplate().merge(detachedInstance);log.debug(merge successful);return result; catch (RuntimeException re) log.error(merge failed, re);throw re;/* * (non-Javadoc) * * see com.frank.dao.impl.S#attachDirty(com.frank.model.Student) */Overridepublic void attachDirty(Student instance) log.debug(attaching dirty Student instance);try getHibernateTemplate().saveOrUpdate(instance);log.debug(attach successful); catch (RuntimeException re) log.error(attach failed, re);throw re;/* * (non-Javadoc) * * see com.frank.dao.impl.S#attachClean(com.frank.model.Student) */Overridepublic void attachClean(Student instance) log.deb
