SSH整合

1.首先我们创建一个Maven项目

然后我们导入jar包因为是maven所以是节点

<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/maven-v4_0_0.xsd"> <parent>

</project>

2.然后我们看一下架构：

3.我们先写实体类我们用的是注解版的所以不需要小配置

package cn.happy.beans;

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

/**
* Created by linlin on 2017/10/13.
*/
@Entity
public class Dept {
@Id
@GeneratedValue
private Integer deptno;
@Column
private String deptname;

public Integer getDeptno() {
return deptno;
}

public void setDeptno(Integer deptno) {
this.deptno = deptno;
}

public String getDeptname() {
return deptname;
}

public void setDeptname(String deptname) {
this.deptname = deptname;
}
}

4.dao层

package cn.happy.dao;

import cn.happy.beans.Dept;
import org.hibernate.Session;

/**
* Created by linlin on 2017/10/13.
*/
public interface IDeptDao {
public int addDept(Dept dept);
}

package cn.happy.dao;

import cn.happy.beans.Dept;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.stereotype.Repository;
import org.springframework.transaction.annotation.Transactional;

import javax.annotation.Resource;
import java.io.Serializable;

/**
* Created by linlin on 2017/10/13.
*/
@Repository("deptDAO")
public class DeptDaoImpl implements IDeptDao{
@Resource
private SessionFactory sessionFactory;

public int addDept(Dept dept) {
Serializable count = sessionFactory.getCurrentSession().save(dept);
return (Integer) count;
}

public SessionFactory getSessionFactory() {
return sessionFactory;
}

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

servier层：
package cn.happy.service;

import cn.happy.beans.Dept;

/**
* Created by linlin on 2017/10/13.
*/
public interface IDeptService {
public int addDept(Dept dept);

}

package cn.happy.service;

import cn.happy.beans.Dept;
import cn.happy.dao.IDeptDao;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

import javax.annotation.Resource;

/**
* Created by linlin on 2017/10/13.
*/
@Service("deptService")
public class DeptServiceImpl implements IDeptService{
@Resource()
private IDeptDao dao;
@Transactional
public int addDept(Dept dept) {
int result=dao.addDept(dept);
return result;
}

public IDeptDao getDao() {
return dao;
}

public void setDao(IDeptDao dao) {
this.dao = dao;
}
}

controller层：

package cn.happy.controller;

import cn.happy.beans.Dept;
import cn.happy.service.IDeptService;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

import javax.annotation.Resource;

/**
* Created by linlin on 2017/10/13.
*/
@Controller
public class DeptController {
@Resource(name="deptService")
private IDeptService deptService;

@RequestMapping("/adds")
public String add(Dept dept){
deptService.addDept(dept);
return "index";
}

public IDeptService getDeptService() {
return deptService;
}

public void setDeptService(IDeptService deptSe
4000
rvice) {
this.deptService = deptService;
}
}

我们写配置文件大配置：

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

jdbc.properties 连接数据库

jdbc.driverClassName=oracle.jdbc.OracleDriver
jdbc.url=jdbc:oracle:thin:@localhost:1521:orcl
jdbc.username=sll
jdbc.password=sll

log4j.properties

log4j.rootLogger=info,Console,R

log4j.appender.Console=org.apache.log4j.ConsoleAppender

log4j.appender.Console.layout=org.apache.log4j.PatternLayout

#log4j.appender.Console.layout.ConversionPattern=%d [%t] %-5p %c - %m%n

log4j.appender.Console.layout.ConversionPattern=%d{yy-MM-dd HH:mm:ss} %5p %c{1}:%L - %m%n

log4j.appender.R=org.apache.log4j.DailyRollingFileAppender

页面：

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
<title>添加部门</title>
</head>
<body>
<form method="post" action="/adds">
部门名称： <input name="deptname"/>
<input type="submit" value="添加"/>
</form>
</body>
</html>

添加成功后

<%@page language="java" pageEncoding="utf-8" %>
<html>
<body>
<h2>login !!!</h2>
</body>
</html>

还有一个就是web.xml

这个是我们必须写的

<!DOCTYPE web-app PUBLIC
"-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd" >
