一、实习已经有大半年了 企业的项目都是搭建好的 自己也学习了去搭建一个 基于SSH的项目整合 其中查阅了很多资料 遇到一些问题也解决了。希望大家可以共同进步。
感谢http://blog.csdn.net/js931178805/article/details/39642743这篇文章。
二、搭建maven项目
（1）新建maven项目
<1>我们选Maven Project
<2>选择maven-archetype-webapp
<3> 填写项目信息
<4> 补全目录 右键--> bulid path
项目基本结构
三、集成jetty 主要在pom 文件 添加配置
pom.xml
<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"> <modelVersion>4.0.0</modelVersion> <groupId>com</groupId> <artifactId>sms</artifactId> <packaging>war</packaging> <version>0.0.1-SNAPSHOT</version> <name>sms Maven Webapp</name> <url>http://maven.apache.org</url> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>3.8.1</version> <scope>test</scope> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.mortbay.jetty</groupId> <artifactId>maven-jetty-plugin</artifactId> <version>6.1.26</version> <configuration> <scanIntervalSeconds>3</scanIntervalSeconds> <connectors> <connector implementation="org.mortbay.jetty.nio.SelectChannelConnector"> <port>8090</port> </connector> </connectors> <scanTargetPatterns> <scanTargetPattern> <directory>src/main/webapp/WEB-INF</directory> <excludes> <exclude>**/*.jsp</exclude> </excludes> <includes> <include>**/*.properties</include> <include>**/*.xml</include> </includes> </scanTargetPattern> </scanTargetPatterns> </configuration> </plugin></plugins> <finalName>sms</finalName> </build></project>
jetty:run
打开浏览器 访问 http://localhost:8090/sms/index.jsp
四、利用maven来下载所有的jar
pom.xml
<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

五、文件配置
配置文件都放在 src/main/resouces 下面
config.properties
#属性文件 #Oracle 的配置 hibernate.dialect=org.hibernate.dialect.OracleDialectdriverClassName=oracle.jdbc.driver.OracleDrivervalidationQuery=SELECT 1 FROM DUALjdbc_url=jdbc:oracle:thin:@127.0.0.1:1521:orcljdbc_username=systemjdbc_password=Oracle123 #SQLServer 的配置 #hibernate.dialect=org.hibernate.dialect.SQLServerDialect #driverClassName=net.sourceforge.jtds.jdbc.Driver #validationQuery=SELECT 1 #jdbc_url=jdbc:jtds:sqlserver://127.0.0.1:1433/sy #jdbc_username= #jdbc_password= #Derby 的配置 #hibernate.dialect=org.hibernate.dialect.DerbyDialect #driverClassName=org.apache.derby.jdbc.EmbeddedDriver #validationQuery=SELECT 1 #jdbc_url=jdbc:derby:sy;create=true #jdbc_username= #jdbc_password= #MySQL 的配置 #hibernate.dialect=org.hibernate.dialect.MySQLDialect #driverClassName=com.mysql.jdbc.Driver #validationQuery=SELECT 1 #jdbc_url=jdbc:mysql://localhost:3306/sshf?useUnicode=true&characterEncoding=utf-8 #jdbc_username=root #jdbc_password=

六、实现一个学生表的增删改查
新建 controller dao model service service.impl包
Student.java
package com.sms.model;import java.io.Serializable;import javax.persistence.Column;import javax.persistence.GeneratedValue;import javax.persistence.Id;import org.hibernate.annotations.AccessType;import org.hibernate.annotations.GenericGenerator;@javax.persistence.Entity@javax.persistence.Table(name = "STUDENT")@AccessType("field")public class Student implements Serializable{private static final long serialVersionUID = 1L;/** * */@Id@Column(name = "ID", length = 32)@GeneratedValue(generator = "uuid") @GenericGenerator(name = "uuid", strategy = "uuid") private String id;/** * */@Column(name = "NAME", length = 10)private String name;/** * */public String getId(){return this.id;}/** * *@param id */public void setId(String id){this.id=id;}/** * */public String getName(){return this.name;}/** * *@param name */public void setName(String name){this.name=name;}}StudentDao.java
package com.sms.dao;import java.util.List;import org.hibernate.Query;import org.hibernate.Session;import org.hibernate.SessionFactory;import org.hibernate.Transaction;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Repository;import org.springframework.transaction.annotation.Transactional;import com.sms.model.Student;@Repositorypublic class StudentDao {@Autowired private SessionFactory sessionFactory; /** * * 获取studentList */public List<Student> getstudentList(){Session session = sessionFactory.openSession();String hql = "from Student"; Query query = session.createQuery(hql); List<Student> studentList = query.list(); session.close();return studentList;}/** * * 根据id删除学生 */public void deleteStudent(String sid){Session session = sessionFactory.openSession();String hql = "delete from Student where id = ? ";Query query = session.createQuery(hql);query.setString(0, sid);query.executeUpdate();session.close();}/** * * 保存学生 */@Transactionalpublic void saveOrUpdate(Student student,String sid){if(!"".equals(sid)&&null!=sid){student.setId(sid);}Session session = sessionFactory.openSession();Transaction tx = session.beginTransaction();session.saveOrUpdate(student);tx.commit();}/** * 获取学生 */public Student getStudent(String sid){Session session = sessionFactory.openSession();return (Student) session.get(Student.class, sid);}}IStudentService.java
package com.sms.service.impl;import java.util.List;import com.sms.model.Student;public interface IStudentService {public List<Student> getStudentList();public void deleteStudent(String sid);public void saveOrUpdateStudent(Student student,String sid);public Student getStudent(String sid);}StudentService.java

package com.sms.controller;import java.util.List;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Controller;import org.springframework.ui.Model;import org.springframework.web.bind.annotation.RequestMapping;import com.sms.model.Student;import com.sms.service.StudentService;@Controllerpublic class StudentController {@Autowiredprivate StudentService service;/** * 获取学生列表 */@RequestMapping("/getstudentList.do")public String getStudentList(Model model){List<Student> list = service.getStudentList();model.addAttribute("slist", list);return "studentList";}/** * 根据id删除学生 */@RequestMapping("/deleteStudent.do")public String deleteStudent(String sid){service.deleteStudent(sid);return "redirect:/getstudentList.do";}/** * * 跳转到新增 编辑学生界面 */@RequestMapping("/addOreditStudent.do")public String toAddStudentPage(String sid,Model model){Student student = new Student();if(!"".equals(sid)&&null!=sid){student = service.getStudent(sid);}else{student = null;}model.addAttribute("student", student);return "addStudentPage";}/** *保存学生 */@RequestMapping("/saveOrupdateStudent.do")public String saveOrUpdateStudent(Student student,String sid){service.saveOrUpdateStudent(student,sid);return "redirect:/getstudentList.do";}}七、前台界面

首页：
学生列表
删除
新增
