Structs 2 Action 与 JQuery Datatable 的整合_JAVA_编程开发_程序员俱乐部

这篇文章主要讲述SSH框架下如何整合AngularJS， JQuery Datatable 以及Bootstrap。?

?

废话少说，进入主题，本篇主要以代码粘贴为主。?

?

第一步：新建Maven项目，pom文件如下：

class="xml" name="code"><project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</project>

?可以看出SSH的版本：

Spring ： 3.1.0.RELEASE

Struts2： 2.3.15

Hibernate ： 4.2.0.Final

?

?第二步: 设置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" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0">

  <url-pattern>/*</url-pattern>
 </filter-mapping>

 
 <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>
        /WEB-INF/dispatcher-servlet.xml
    </param-value>
</context-param>

 <listener>
  <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
 </listener>

 <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>*.action</url-pattern>  
    </filter-mapping>  
</web-app>

?

?

第三步：设置dispatcher-servlet.xml

?

<?xml version="1.0" encoding="UTF-8"?>

?第四步，准备css和js目录

?

1. 从JQuery官网下载最新的jquery.min.js ，copy到js目录，这里我下载的是jQuery v1.11.1

2. 从Bootstrap官网下载最新的bootstrap.min.js，?bootstrap.min.css，分别copy到js和css目录中，这里我下载的是Bootstrap v3.3.0

3. 从Datatables官网下载最新的jquery.dataTables.min.js，?dataTables.bootstrap.min.js，dataTables.bootstrap.css， 分别copy到js和css目录中，?

目录结构如下：

第五步：写hibernate实体类

?

package com.boyi.web.entity;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;

@Entity
@Table(name = "PERSON")
public class Person {

	@Id
	@GeneratedValue(strategy = GenerationType.AUTO)
	private int id;

	@Column(name = "NAME")
	private String name;

	@Column(name = "BIRTHDAY")
	private String birth;

	@Column(name = "GENDER")
	private String gender;

	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 String getBirth() {
		return birth;
	}

	public void setBirth(String birth) {
		this.birth = birth;
	}

	public String getGender() {
		return gender;
	}

	public void setGender(String gender) {
		this.gender = gender;
	}

}

?
?第六步：写hibernateDAO超类

?

?

package com.boyi.web.dao;

import java.io.Serializable;
import java.util.List;

import org.hibernate.Query;
import org.hibernate.Session;
import org.hibernate.criterion.Criterion;

public interface HqlBaseDao<T, PK extends Serializable> {
	int count();
	 /**

    /**

     */
    T load(PK id, Session session);

    /**
     * Loads the given Object.
     * @param id Id to load
     * @param session to use
     * @return An object of type T
     */
    T get(PK id, Session session);

    /** Save object to disk using given session.
     * @param o to save
     * @param session to use
     * @return the id of the saved object
     * 
     */
    PK save(T o, Session session);

    /** Save or update given object.
     * @param o item to save.
     * @param session to use
     * 
     */
    void saveOrUpdate(T o, Session session); 

    /** Update given object.
     * @param o item to update

     * 
     */
    void update(T o, Session session); 
    
    /** Refreshes the object of type T.
     * @param persistentObject to refresh
     */
    void refresh(T persistentObject);
    
    /**
     * Get a query handle.
     * @param s Query to use
     * @param session to use
     * @return Query object
     */
    Query getQuery(String s, Session session);

    /** FindByExample.
     * @param exampleInstance to use
     * @param excludeProperty to exclude
     * @return A list of objects
     */
    List<T> findByExample(T exampleInstance, String... excludeProperty);
    
    /** Returns a list of objects.
     * @return list of objects
     */
    List<T> findAll();
    
    List<T> findListForPage(String hql, Integer page, Integer size, Object... objects);
    
    /** Flushes the cache of the currently-used session.
     * 
     */
    void flush();
    
    /** Object to evict from cache.
     * @param obj Object to evict
     */
    void evict(Object obj);
    
    /** Hibernate wrapper.

?第七步：写hibernateDAO类

?

package com.boyi.web.dao;

import java.io.Serializable;
import java.util.List;

import com.boyi.web.entity.Person;

public interface PersonDao extends HqlBaseDao<Person, Serializable> {
	
	
	/**
	 * 
	 * @param page
	 * @param pageSize
	 * @return the person by pagination
	 * @throws Exception
	 */
	public List<Person> list(Integer page, Integer pageSize) throws Exception;
}

?

package com.boyi.web.dao.impl;

import java.io.Serializable;
import java.util.List;

import org.springframework.stereotype.Repository;

import com.boyi.web.dao.PersonDao;
import com.boyi.web.entity.Person;

@Repository 
public class PersonDaoImpl extends HqlBaseDaoImpl<Person, Serializable> implements PersonDao {

	public PersonDaoImpl() {
		super(Person.class);
	}
	
	public List<Person> list(Integer page, Integer pageSize) throws Exception {
		return findListForPage("from Person", page, pageSize);
	}

}

??第八步：写Service类

package com.boyi.web.service;

import java.util.List;

import com.boyi.web.entity.Person;

public interface PersonService {
	/**
	 * return the person counts
	 * @return
	 * @throws Exception
	 */
	public int count() throws Exception;
	
	/**
	 * 
	 * @param page
	 * @param pageSize
	 * @return the person by pagination
	 * @throws Exception
	 */
	public List<Person> list(Integer page, Integer pageSize) throws Exception;
}

?

package com.boyi.web.service.impl;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import com.boyi.web.dao.PersonDao;
import com.boyi.web.entity.Person;
import com.boyi.web.service.PersonService;

@Service
public class PersonServiceImpl implements PersonService {

	@Autowired
	PersonDao dao;
	
	public int count() throws Exception {
		return dao.count();
	}

	public List<Person> list(Integer page, Integer pageSize) throws Exception {
		return dao.list(page, pageSize);
	}

}

? 第九步：写Action类

package com.boyi.web.action;

import java.util.List;

import javax.annotation.Resource;

import org.apache.struts2.convention.annotation.Action;
import org.apache.struts2.convention.annotation.ParentPackage;

import com.boyi.web.entity.Person;
import com.boyi.web.service.PersonService;
import com.opensymphony.xwork2.ActionSupport;

@ParentPackage("json-default")
@Controller
public class PersonAjaxAction extends ActionSupport {

	private static final long serialVersionUID = 1L;

	/**
	 * datatable start value
	 */
	private int start;

	/**
	 * datatable page size
	 */
	private int length;
	private int recordsTotal;
	private int recordsFiltered;
	private int recordsDisplay;
	private List<Person> aaData;
	@Resource
	PersonService service;

	@Override
	@Action(value = "/persons", results = { @Result(name = "success", type = "json") })
	public String execute() throws Exception {
		// calculate the total records
		recordsTotal = service.count();

		// calculate the current page
		int page = start / length + 1;

		// query the persons
		aaData = service.list(page, length);
		
		recordsFiltered = recordsTotal;
		
		recordsDisplay = aaData.size();
		
		return ActionSupport.SUCCESS;
	}

	public int getStart() {
		return start;
	}

	public void setStart(int start) {
		this.start = start;
	}

	public int getLength() {
		return length;
	}

	public void setLength(int length) {
		this.length = length;
	}

	public int getRecordsTotal() {
		return recordsTotal;
	}

	public void setRecordsTotal(int recordsTotal) {
		this.recordsTotal = recordsTotal;
	}

	public int getRecordsFiltered() {
		return recordsFiltered;
	}

	public void setRecordsFiltered(int recordsFiltered) {
		this.recordsFiltered = recordsFiltered;
	}

	public List<Person> getAaData() {
		return aaData;
	}

	public void setAaData(List<Person> aaData) {
		this.aaData = aaData;
	}

	public static long getSerialversionuid() {
		return serialVersionUID;
	}

	public int getRecordsDisplay() {
		return recordsDisplay;
	}

	public void setRecordsDisplay(int recordsDisplay) {
		this.recordsDisplay = recordsDisplay;
	}
	
}

? 第十步：写JSP

? 第十一步：写JS

$(document).ready(function() {

	$("#example").dataTable({
		dom:
			"<'row'<'col-sm-12'tr>>" +
			"<'row'<'col-sm-3'i><'col-sm-3'l><'col-sm-6'p>>",

		"paginationType" : "full_numbers",
		"lengthMenu" : [ 5, 10, 25, 50, 75, 100 ],
		"ajax" : {
			"url" : "persons.action",
			"type" : "POST"
		},
		"columns" : [ {
			"title" : "ID",
			"data" : "id",
			"visible" : true,
			"orderable" : true,
			"render" : function(data, type, full, meta){

?第十二步：数据库建表

DROP DATABASE IF EXISTS `ssh`;
CREATE DATABASE IF NOT EXISTS `ssh` 
USE `ssh`;

DROP TABLE IF EXISTS `PERSON`;
CREATE TABLE IF NOT EXISTS `PERSON` (
  `ID` int(9) NOT NULL AUTO_INCREMENT,

  `BIRTHDAY` varchar(20) NOT NULL,
  `GENDER` varchar(5) NOT NULL,
  PRIMARY KEY (`ID`)
) ENGINE=InnoDB AUTO_INCREMENT=22 DEFAULT CHARSET=utf8;
INSERT INTO `PERSON` (`ID`, `NAME`, `BIRTHDAY`, `GENDER`) VALUES
	(1, 'NAME1', '1984-01-02', '男'),
	(2, 'NAME2', '1984-01-03', '男'),
	(3, 'NAME3', '1984-01-04', '男'),
