Structs 2 Action 与 JQuery Datatable 的整合

博客分类：

Java AngularJS SSH JQuery Datatable

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：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
	<modelVersion>4.0.0</modelVersion>

	<artifactId>ssh-datatabase-example</artifactId>

	<packaging>war</packaging>

	<properties>

		<hibernate.version>4.2.0.Final</hibernate.version>
		<mysql.version>5.1.6</mysql.version>
	</properties>

	<dependencies>

	</dependencies>
	<build>
		<finalName>ssh</finalName>
	</build>
</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">
  <display-name>ssh-datatable-example</display-name>
  <filter>
  <filter-name>CharacterEncoding</filter-name>
  <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
  <init-param>
   <param-name>encoding</param-name>
   <param-value>UTF-8</param-value>
  </init-param>
  <init-param>
   <param-name>forceEncoding</param-name>
   <param-value>true</param-value>
  </init-param>
 </filter>
  <filter-mapping>
  <filter-name>CharacterEncoding</filter-name>
  <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();
	 /** 
     * Persist the newInstance object into database.
     * @param newInstance to save
     * @return The identifier
     **/
    PK save(T newInstance);

    /**
     * Save or update.
     * @param transientObject to save
     */
    void saveOrUpdate(T transientObject);
    
    /** 
     * Retrieve a persisted object with a given id from the database.
     * @param id to load
     * @return An object of type T
     */
    T load(PK id);
    
    /** 
     * Retrieve a persisted object with a given id from the database.
     * @param id to get
     * @return An object of type T
     */
    T get(PK id);
    /** 
     * Save changes made to a persistent object.  
     * @param transientObject object to update
     **/
    void update(T transientObject);

    /** 
     * Remove the given object from persistent storage in the database.
     * @param persistentObject object to delete.
     **/
    void delete(T persistentObject);
    
    /** 
     * Remove the given object from persistent storage in the database. 
     * @param s Query to execute 
     * @return A query object
     **/
    Query getQuery(String s);
    
    /** Deletes an object of a given Id. Will load the object internally so 
     * consider using delete (T obj) directly.
     * @param id Id of record
     */
    void delete(PK id);
    
    
    /** Delete object from disk.
     * @param persistentObject to delete
     * @param session to use
     * 
     */
    void delete(T persistentObject, Session session);

    /** Deletes an object of a given Id. Will load the object internally so consider using delete (T obj) directly.
     * @param id to delete 
     * @param session to use
     */
    void delete(PK id, Session session);

    /**
     * Loads the given Object.
     * @param id to load
     * @param session to use
     * @return  an object of type T
     */
    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 
     * @param session to use
     * 
     */
    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.
     * @param criterion to filter.
     * @return list of objects
     */
    List<T> findByCriteria(Criterion... criterion);
}

}

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 org.apache.struts2.convention.annotation.Result;
import org.springframework.stereotype.Controller;

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

<%@ page language="java" contentType="text/html; charset=UTF-8"
	pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>SHH - Datatable - Example</title>
<link rel='stylesheet' type='text/css' href='css/bootstrap.min.css'>
<link rel='stylesheet' type='text/css' href='css/dataTables.bootstrap.css'>
</head>
<body>
	<hr>
	<center>
		<h1>SHH - Datatable - Example</h1>
	</center>
	<hr>
	<div class="container">
		<div class="row">
			<table class="table table-striped table-bordered table-hover datatable" id="example"></table>
		</div>
		
	</div>
	
	<script src='js/jquery.min.js'></script>
	<script src='js/jquery.dataTables.min.js'></script>
	<script src='js/dataTables.bootstrap.min.js'></script>
	<script src='js/bootstrap.min.js'></script>
	<script src='js/index.js'></script>
</body>
</html>

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>>",
		"processing" : true,
		"serverSide" : true,
		"length" : 5,
		"paging" : true,
		"ordering" : true,
		"pageLength" : 5,
		"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){
				return '<a href="http://www.baidu.com">' + data +'</a>';
			}
		}, {
			"title" : "NAME",
			"data" : "name",
			"visible" : true,
			"orderable" : true
		}, {
			"title" : "BIRTHDAY",
			"data" : "birth",
			"visible" : true,
			"orderable" : true
		}, {
			"title" : "GENDER",
			"data" : "gender",
			"visible" : true,
			"orderable" : true
		} ],
		"language" : {
			"emptyTable" : "没有数据",
			"info" : "显示 第 _START_ 到 _END_ 条数据  总共 _TOTAL_ 条数据 ",
			"infoEmpty" : "没有数据",
			"infoFiltered" : "(filtered from _MAX_ total entries)",
			"infoPostFix" : "",
			"thousands" : ",",
			"lengthMenu" : "每页显示条数 _MENU_ ",
			"loadingRecords" : "加载中...",
			"processing" : "处理中...",
			"search" : "搜索:",
			"zeroRecords" : "找不到匹配的数据",
			"paginate" : {
				"first" : "首页",
				"last" : "尾页",
				"next" : "下页",
				"previous" : "上页"
			}
		}
	});

});

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,
  `NAME` varchar(20) NOT NULL,
  `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'),
	(4, 'NAME4', '1984-01-05', '女'),
	(5, 'NAME5', '1984-01-06', '男'),
	(6, 'NAME6', '1984-01-07', '女'),
	(7, 'NAME7', '1984-01-08', '男'),
	(8, 'NAME8', '1984-01-09', '男'),
	(9, 'NAME9', '1984-01-10', '男'),
	(10, 'NAME10', '1984-01-11', '女'),
	(11, 'NAME11', '1984-01-12', '男'),
	(12, 'NAME12', '1984-01-13', '男'),
	(13, 'NAME13', '1984-01-14', '女'),
	(14, 'NAME14', '1984-01-15', '男'),
	(15, 'NAME15', '1984-01-16', '男'),
	(16, 'NAME16', '1984-01-17', '女'),
	(17, 'NAME17', '1984-01-18', '男'),
	(18, 'NAME18', '1984-01-19', '人妖'),
	(19, 'NAME19', '1984-01-20', '男'),
	(20, 'NAME20', '1984-01-12', '男'),
	(21, 'NAME21', '1984-01-22', '男');
