structs +hibernate 通过Action 将前台数据存入数据库 ， 表单提交
逻辑：前台jsp中的form，调用action中的add方法，action中通过定义和页面元素相同的私有变量（生成get、set方法可以拿到前台变量），然后调用dao中的hibernate保存
1、struts.xml
采用通配符配置
<action name="test_*" class="com.action.TestAction" method="{1}">
<result name="add_sucess">/test/addTestSucess.jsp</result>
<result name="search_sucess">/test/searchTest.jsp</result>
</action>
2、前台页面 addTest.jsp
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%@ taglib uri="/struts-tags" prefix="s"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<body style="background:#F5F5F5">
<div>
<ol class="breadcrumb">
<li class="active">测试</a></li>
<li class="active">添加</li>
</ol>
<div id="content">
<form action="test_add.action" method="post" id="test">
<table class="table table-bordered" border="0" width="100%" align="center">

<td style="width: 270px; height: 18px;">

3、TestAction
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import com.bean.TestPortal;
import com.service.TestService;
import com.opensymphony.xwork2.ActionSupport;
/**
* 测试action
* @author anjl
*
*/
public class TestAction extends ActionSupport {
private static final long serialVersionUID = 1L;
@Autowired
private TestService testService;
private String a="";
private String b="";
private String c="";
/*private int page =1;
private String op;*/
private List<TestPortal> list;
public List<TestPortal> getList() {
return list;
}
public void setList(List<TestPortal> list) {
this.list = list;
}
public String getA() {
return a;
}
public void setA(String a) {
this.a = a;
}
public String getB() {
return b;
}
public void setB(String b) {
this.b = b;
}
public String getC() {
return c;
}
public void setC(String c) {
this.c = c;
}
public String add() {
System.out.println("==add===="+getA());
TestPortal t = new TestPortal(getA(),getB(),getC());
testService.add(t);
return "add_sucess";
}
public String search(){
/*if(op!=null&&op.equals("first")){
page=1;
}else if(op!=null&&op.equals("before")){
page = page-1;
}else if(op!=null&&op.equals("after")){
page = page+1;
}*/
System.out.println("==========search=========");
list = testService.search(getA(), getB(), getC());
return "search_sucess";
}
}
4、bean TestPortal 和数据表对应
import java.io.Serializable;
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="testPortal")
public class TestPortal implements Serializable{
private static final long serialVersionUID = 1L;
public TestPortal(){
}
public TestPortal(String a,String b,String c){
this.a=a;
this.b=b;
this.c=c;
}
@Id
@GeneratedValue(strategy=GenerationType.AUTO)
@Column(name = "id")
private Long id;
@Column(name = "a")
private String a;
@Column(name = "b")
private String b;
@Column(name = "c")
private String c;
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getA() {
return a;
}
public void setA(String a) {
this.a = a;
}
public String getB() {
return b;
}
public void setB(String b) {
this.b = b;
}
public String getC() {
return c;
}
public void setC(String c) {
this.c = c;
}
}
5、service层和dao层
主要是dao层，service没做处理
（1）、TestDaoImpl
import java.util.List;
import javax.annotation.Resource;
import org.hibernate.Query;
import org.hibernate.Session;
import org.hibernate.Transaction;
import org.springframework.orm.hibernate3.HibernateTemplate;
import org.springframework.stereotype.Repository;
import com.haier.bean.TestPortal;
import com.haier.dao.TestDao;
@Repository("testDao")
public class TestDaoImpl implements TestDao {
private HibernateTemplate hibernateTemplate;
public HibernateTemplate getHibernateTemplate() {
return hibernateTemplate;
}
@Resource
public void setHibernateTemplate(HibernateTemplate hibernateTemplate) {
this.hibernateTemplate = hibernateTemplate;
}
@Override
public void add(TestPortal t) {
Session session = this.getHibernateTemplate().getSessionFactory()
.getCurrentSession();
session.save(t);
}
@Override
public List<TestPortal> search(String a, String b, String c) {
Session session = this.getHibernateTemplate().getSessionFactory()
.getCurrentSession();
StringBuffer hql = new StringBuffer("from TestPortal testPortal where 1=1 ");
if(!"".equals(a) && null!=a){
hql.append(" and a='"+a+"' ");
}
if(!"".equals(b) && null!=b){
hql.append(" and b='"+b+"' ");
}
if(!"".equals(c) && null!=c){
hql.append(" and c='"+c+"' ");
}
List<TestPortal> list =null;
System.out.println("search hql : "+hql.toString());
Query query = session.createQuery(hql.toString());
list = query.list();
return list;
}
}
（2）、service 没做处理
import java.util.List;
import javax.annotation.Resource;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import com.gp.dao.UserDao;
import com.haier.bean.TestPortal;
import com.haier.dao.TestDao;
import com.haier.service.TestService;
@Service("testService")
public class TestServiceImpl implements TestService{
private TestDao testDao;
public TestDao getTestDao() {
return testDao;
}
@Resource(name="testDao")
public void setTestDao(TestDao testDao) {
this.testDao = testDao;
}
@Override
public void add(TestPortal t) {
testDao.add(t);
}
@Override
public List<TestPortal> search(String a, String b, String c) {
List<TestPortal> list = testDao.search(a, b, c);
return list;
}
}
