SSH三大框架的整合+利用Ajax实现无刷新分页

以下是我利用Struts2.3.24、Spring4.0、Hibernate4.2 结合Mysql数据库进行的ssh整合，实现分页需要json.js

首先ssh的整合需要导入所有的jar包

在web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">
<display-name>testssh</display-name>
<!-- 加载Struts配置文件 -->
<filter>
<filter-name>struts2</filter-name>
<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<!--加载spring  -->
<!-- needed for ContextLoaderListener -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext-*.xml</param-value>
</context-param>

<!-- Bootstraps the root web application context before servlet initialization -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
</web-app>

接下来需要加入实体类与数据库相连接

Person.java

package com.zking.entity;

public class Person {
private int pid;
private String pname;
private int page;
public int getPid() {
return pid;
}
public void setPid(int pid) {
this.pid = pid;
}
public String getPname() {
return pname;
}
public void setPname(String pname) {
this.pname = pname;
}
public int getPage() {
return page;
}
public void setPage(int page) {
this.page = page;
}
public Person(String pname, int page) {
super();
this.pname = pname;
this.page = page;
}
public Person() {
super();
// TODO Auto-generated constructor stub
}

}

加入是实体类的映射文件

Person.hbm.xml

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<!-- Generated 2017-2-18 20:09:46 by Hibernate Tools 3.4.0.CR1 -->
<hibernate-mapping>
<class name="com.zking.entity.Person" table="PERSON">
<id name="pid" type="int">
<column name="PID" />
<generator class="native" />
</id>
<property name="pname" type="java.lang.String">
<column name="PNAME" />
</property>
<property name="page" type="int">
<column name="PAGE" />
</property>
</class>
</hibernate-mapping>

写一个PersoDao.java

package com.zking.dao;

import java.util.List;

import com.zking.entity.Person;

public interface PersonDao {
public void addPerson(Person person);
public List<Person> getPersons(int pageNo,int pageSize);
}

用PersonDaoImp.java实现PersonDao

package com.zking.dao;

import java.util.List;

import org.hibernate.Session;
import org.hibernate.SessionFactory;

import com.zking.entity.Person;

public class PersonDaoImp implements PersonDao {
private SessionFactory sessionFactory;
public SessionFactory getSessionFactory() {
return sessionFactory;
}

public void setSessionFactory(SessionFactory sessionFactory) {
this.sessionFactory = sessionFactory;
}

public Session getSession(){
return sessionFactory.getCurrentSession();
}

@Override
public void addPerson(Person person) {
getSession().save(person);
}

@Override
public List<Person> getPersons(int pageNo,int pageSize) {
List<Person> persons=getSession().createQuery("from Person")
.setFirstResult((pageNo-1)*pageSize)//从第几条开始拿
.setMaxResults(pageSize)//每次拿几条
.list();
return persons;
}
}

PersonBiz.java

package com.zking.biz;

import java.util.List;

import com.zking.entity.Person;

public interface PersonBiz {
public void addPerson(Person person);
public List<Person> getPersons(int pageNo,int pageSize);
}

PersonBizImp.java

package com.zking.biz;

import java.util.List;

import com.zking.dao.PersonDao;
import com.zking.entity.Person;

public class PersonBizImp implements PersonBiz{

private PersonDao personDao;
public PersonDao getPersonDao() {
return personDao;
}

public void setPersonDao(PersonDao personDao) {
this.personDao = personDao;
}

@Override
public void addPerson(Person person) {
personDao.addPerson(person);
}

@Override
public List<Person> getPersons(int pageNo,int pageSize) {
return personDao.getPersons(pageNo,pageSize);
}

}

PersonAction.java

package com.zking.action;

import java.io.IOException;
import java.io.PrintWriter;
import java.util.List;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.struts2.ServletActionContext;

import com.opensymphony.xwork2.ActionSupport;
import com.zking.biz.PersonBiz;
import com.zking.entity.Person;

import net.sf.json.JSONArray;

public class PersonAction extends ActionSupport{
/**
*
*/
private static final long serialVersionUID = 1L;
private Person person;
private PersonBiz personBiz;

private int pageNo=1;
private int pageSize=5;

public int getPageNo() {
return pageNo;
}

public void setPageNo(int pageNo) {
this.pageNo = pageNo;
}

public int getPageSize() {
return pageSize;
}

public void setPageSize(int pageSize) {
this.pageSize = pageSize;
}

public PersonBiz getPersonBiz() {
return personBiz;
}

public void setPersonBiz(PersonBiz personBiz) {
this.personBiz = personBiz;
}

public void setPerson(Person person) {
this.person = person;
}

public Person getPerson() {
return person;
}

public String add() throws Exception {
// TODO Auto-generated method stub
System.out.println("wwwwwwwww");
System.out.println("添加"+person.getPname()+person.getPage());
personBiz.addPerson(person);
//展示
List<Person> persons=personBiz.getPersons(pageNo, pageSize);
//得到请求域
ServletActionContext.getRequest().setAttribute("persons", persons);

return "success";
}

//chaxun
public void query(){

System.out.println("pageNo"+pageNo);
List<Person> persons=personBiz.getPersons(pageNo, pageSize);
//把查询到的值转为json（对象集合转json）
JSONArray jsonArray=new JSONArray();
jsonArray=JSONArray.fromObject(persons);
String str=jsonArray.toString();

try {
HttpServletResponse response=ServletActionContext.getResponse();
response.setCharacterEncoding("utf-8");
PrintWriter printWriter=response.getWriter();
printWriter.write(str);
printWriter.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

}

}

接下来是关键的配置文件

struts.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
"http://struts.apache.org/dtds/struts-2.3.dtd">
<struts>
<package name="myPackage" extends="struts-default">
<action name="personAction*" class="personAction" method="{1}">
<result name="success">/success.jsp</result>
</action>

</package>
</struts>

hibernate.cfg.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

<property name="show_sql">true</property>
<property name="format_sql">true</property>

</session-factory>
</hibernate-configuration>

db.properties连接数据库的信息

initPoolSize=5
maxPoolSize=10
