2、applicationContext.xml（spring配置文件）

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

    	<aop:aspectj-autoproxy></aop:aspectj-autoproxy>
    
    </beans>

3、struts.xml（struts2配置）

<?xml version="1.0" encoding="UTF-8"?>
    
    <!DOCTYPE struts PUBLIC
    	"-//Apache Software Foundation//DTD Struts Configuration 2.5//EN"
    	"http://struts.apache.org/dtds/struts-2.5.dtd">
    
    <struts>

    	<interceptor-ref name="myi"></interceptor-ref>
    	
    	</action>
    	</package>
    
    </struts>

4、dbconfig.properties（数据库配置，引用阿里巴巴的druid）

jdbc.driver=com.mysql.jdbc.Driver
    jdbc.url=jdbc:mysql://localhost:3306/qf?characterEncoding=UTF-8
    jdbc.username=root
    jdbc.password=123456

5、log4j.properties（日志文件，debug级）

6、web.xml

<?xml version="1.0" encoding="UTF-8"?>
    <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    	xmlns="http://xmlns.jcp.org/xml/ns/javaee"
    	xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
    	version="3.1">
    	<display-name>day21_S2SH</display-name>
    	<welcome-file-list>
    		<welcome-file>student.jsp</welcome-file>

    	<context-param>
    		<param-name>contextConfigLocation</param-name>
    		<param-value>classpath:applicationContext.xml</param-value>

    		<filter-name>struts2</filter-name>
    		<url-pattern>/*</url-pattern>
    	</filter-mapping>
    </web-app>

7、控制器示例（包含上传文件）

@Controller
    public class StudentAction extends ActionSupport implements ModelDriven<Student>{
    
    	@Autowired
    	private StudentService service;
    
    	//上传的文件
    	private File fileupload;
    	//上传的文件名称
    	private String fileuploadFileName;
    	//上传文件的MIME类型
    	private String fileuploadContentType;
    	
    	
    	
    	public File getFileupload() {
    		return fileupload;
    	}
    
    	public void setFileupload(File fileupload) {
    		this.fileupload = fileupload;
    	}
    
    	public String getFileuploadFileName() {
    		return fileuploadFileName;
    	}
    
    	public void setFileuploadFileName(String fileuploadFileName) {
    		this.fileuploadFileName = fileuploadFileName;
    	}
    
    	public String getFileuploadContentType() {
    		return fileuploadContentType;
    	}
    
    	public void setFileuploadContentType(String fileuploadContentType) {
    		this.fileuploadContentType = fileuploadContentType;
    	}
    	private Student  stu=new Student();
    	@Override
    	public Student getModel() {
    		// TODO Auto-generated method stub
    		return stu;
    	}
    	
    	//新增
    	public String add() throws IOException {
    		//进行头像的保存
    		HttpServletRequest request=ServletActionContext.getRequest();
    		File dir=new File(new File(request.getServletContext().getRealPath("/")).getParent(),"s2shImages");
    		if(!dir.exists()) {
    			dir.mkdirs();
    		}
    		//创建要保存的File对象
    		File file=new File(dir, fileuploadFileName);
    		//将上传的文件保存到服务器
    		FileUtils.copyFile(fileupload, file);
    		//设置图片的路径
    		stu.setImgurl(dir.getName()+File.separator+file.getName());
    		
    		System.out.println("新增："+service.save(stu));
    		return "success";
    		
    	}
    	//删除
    	public String delete() {
    		service.delete(stu);
    		return "success";
    		
    	}
    	//修改
    	public String update() {
    		service.update(stu);
    		return "success";
    		
    	}
    	//查询
    	public String query() {
    		HttpServletRequest request=ServletActionContext.getRequest();
    		
    		request.setAttribute("list", service.queryAll());
    		
    		return "success";
    		
    	}

8、service层

@Service
    @Transactional
    public class StudentService {
    
    	@Autowired
    	private StudentDao dao;
    
    	// 新增
    	public Long save(Student student) {
    		return dao.save(student);
    	}
    
    	// 修改
    	public void update(Student student) {
    		dao.update(student);
    	}
    
    	// 删除
    	public void delete(Student student) {
    		dao.delete(student);
    	}
    
    	// 查询
    	public List<Student> queryAll() {
    		return dao.queryAll();
    	}
    }

9、dao层

@Repository
    public class StudentDao {
    	@Autowired
    	private SessionFactory factory;
    	//新增
    	public Long save(Student student) {
    		return (Long)factory.getCurrentSession().save(student);
    	}
    	//修改
    	public void update(Student student) {
    		 factory.getCurrentSession().update(student);
    	}
    	//删除
    	public void delete(Student student) {
    		factory.getCurrentSession().delete(student);
    	}
    	//查询
    	public List<Student> queryAll() {
    		return factory.getCurrentSession().createQuery("from Student", Student.class).getResultList();
    	}
    }

10.domain层（实体层）

@Entity
    @Table(name="t_student")
    public class Student implements Serializable{
    
    
    	@Id
    	@GeneratedValue(strategy=GenerationType.IDENTITY)
    	private Long id;
    	@Column(length=10)
    	private String name;
    	@Column(length=2)
    	private String sex;
    	private int age;
    	@Column(length=11)
    	private String phone;
    	@Column(length=200)
    	private String imgurl;
    	
    	public String getImgurl() {
    		return imgurl;
    	}
    	public void setImgurl(String imgurl) {
    		this.imgurl = imgurl;
    	}
    	public Long getId() {
    		return id;
    	}
    	public void setId(Long id) {
    		this.id = id;
    	}
    	public String getName() {
    		return name;
    	}
    	public void setName(String name) {
    		this.name = name;
    	}
    	public String getSex() {
    		return sex;
    	}
    	public void setSex(String sex) {
    		this.sex = sex;
    	}
    	public int getAge() {
    		return age;
    	}
    	public void setAge(int age) {
    		this.age = age;
    	}
    	public String getPhone() {
    		return phone;
    	}
    	public void setPhone(String phone) {
    		this.phone = phone;
    	}
    }
