MyEclipse搭建SSH並實現增刪改查
一、 新建一個web專案命名為ssh
完成之後目錄結構
二、 為工程加上Struts2的支援
然後是選擇struts的包，根據需要將struts的包新增進來，一般需要新增的包如下
Struts Core libraries
Struts必須包
StrutsSpring libraries
Spring支援包
三、 為工程加上Spring的支援
如果選擇next進入下一步，裡面是指定spring配置檔案的位置，
一般都不需要修改直接點finish就可以了，這樣就使你的工程新增進了spring的支援
四、 為工程加上hibernate的支援
然後點finish，完成hibernate的配置
在web.xml檔案必須新增如下配置
<!-- spring監聽器 -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>
執行結果
專案結構如下
新建一個TestAction
package com.xwd.action;
import java.util.List;
import com.xwd.entity.User;
import com.xwd.service.TestService;
public class TestAction {
private User user;
private TestService testservice;
private List list;
public String execute(){
int save=testservice.add(user);
System.out.println("save:"+save);
list=testservice.findAll(User.class);
return "success";
}
public String delete(){
testservice.delete(User.class,user.getId());
System.out.println("delete:"+1);
//錕斤拷詢錕斤拷錕斤拷錕斤拷錕斤拷錕斤拷,錕斤拷示頁錕斤拷
list=testservice.findAll(User.class);
return "success";
}
public String update(){
int update = testservice.update(user);
System.out.println("update:"+update);
//錕斤拷詢錕斤拷錕斤拷錕斤拷錕斤拷錕斤拷,錕斤拷示頁錕斤拷
list = testservice.findAll(User.class);
return "success";
}
public User getUser() {
return user;
}
public void setUser(User user) {
this.user = user;
}
public TestService getTestservice() {
return testservice;
}
public void setTestservice(TestService testservice) {
this.testservice = testservice;
}
public List getList() {
return list;
}
public void setList(List list) {
this.list = list;
}
}
新建一個TestDao
package com.xwd.dao;
import java.io.Serializable;
import java.util.List;
import org.hibernate.HibernateException;
import org.hibernate.Query;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
public class TestDao {
private SessionFactory sf;
public int insert(Object o){
try {
Session session=sf.getCurrentSession();
session.save(o);
return 1;
} catch (HibernateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return -1;
}
public int delete(Class cls,Serializable id){
try {
Session session=sf.getCurrentSession();
Object o = session.get(cls,id);
session.delete(o);
return 1;
} catch (HibernateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return -1;
}
public int update(Object o){
try {
Session session=sf.getCurrentSession();
session.update(o);
return 1;
} catch (HibernateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return -1;
}
public List getAll(Class cls){
Session session=sf.getCurrentSession();
Query query = session.createQuery("from "+cls.getSimpleName());
System.out.println("TestDao getAll cls.getSimpleName()"+cls.getSimpleName());
return query.list();
}
public SessionFactory getSf() {
return sf;
}
public void setSf(SessionFactory sf) {
this.sf = sf;
}
}
新建一個User
package com.xwd.entity;
public class User {
private int id;
private String name;
private int pwd;
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;
}
public int getPwd() {
return pwd;
}
public void setPwd(int pwd) {
this.pwd = pwd;
}
public User(int id, String name, int pwd) {
this.id = id;
this.name = name;
this.pwd = pwd;
}
public User() {
}
@Override
public String toString() {
return "User{" +
"id=" + id +
", name='" + name + '\'' +
", pwd=" + pwd +
'}';
}
}
新建一個User.hbm.xml
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">
<hibernate-mapping>
<class name="com.xwd.entity.User" table="user">
<id name="id">
<generator class="native"/>
</id>
<property name="name"/>
<property name="pwd"/>
</class>
</hibernate-mapping>
新建一個TestService
package com.xwd.service;
import java.io.Serializable;
import java.util.List;
import org.hibernate.HibernateException;
import org.hibernate.Query;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import com.xwd.dao.TestDao;
import com.xwd.entity.User;
public class TestService {
private SessionFactory sf;
private TestDao testdao;
public int add(Object o){//新增
System.out.println("我在TestService類中,新增的方法運行了"+o);
return testdao.insert(o);
}
public int delete(Class cls,Serializable id){//刪除
System.out.println("我在TestService類中,刪除的方法運行了");
return testdao.delete(cls, id);
}
public int update(Object o){//修改
System.out.println("我在TestService類中,修改的方法運行了"+o);
return testdao.update(o);
}
public List findAll(Class cls){//查詢
System.out.println("我在TestService類中,查詢的方法運行了");
return testdao.getAll(cls);
}
public SessionFactory getSf() {
return sf;
}
public void setSf(SessionFactory sf) {
this.sf = sf;
}
public TestDao getTestdao() {
return testdao;
}
public void setTestdao(TestDao testdao) {
this.testdao = testdao;
}
}
