spring、spring mvc、hibernate框架集成（ssh搭建,简单实例）
spring、spring mvc、hibernate三大框架集成
开发工具：Eclipse
jdk版本：1.8
tomcat：8.5
前段框架：bootstrap
项目结构：
第一步：pom.xml 文件导包
各种包可以去maven公共库

第二步：配置spring—mvc.xml文件：
第三步：定义实体类，写java分层代码，运用aop面向切面注入对象，映射关系文件配置。
1、我们定义一个双向一对多的映射关系，一个作者对应多本书籍，多本书籍同样可以对应一个作者。
/**
* *作者实体类
* @author Administrator
*
*/
public class Author {
private int aid;
private String name;
private String password;
private Set books = new HashSet();//保存书籍的集合
此处省略get（）和set（）方法...
/**
* *书籍实体类
* @author Administrator
*
*/
public class Book {
private int bid;
private String bookname;
private Author author;//保存作者对象
同样省略get（）和set（）方法
Author.xml文件：
seq_author_id
Book.xml文件：
seq_book_id
AuthorDao:
public interface AuthorDao {
public Author getAuthorByName(Author author);//通过名字查找作者
}
AuthorDaoImpl:
@Component("authorDaoImpl")//把authorDaoImpl实例化到spring容器中
public class AuthorDaoImpl implements AuthorDao{
private SessionFactory sessionFactory;
@Resource//装配bean，默认取属性名进行装配
public void setSessionFactory(SessionFactory sessionFactory) {
this.sessionFactory = sessionFactory;
}
@Override
public Author getAuthorByName(Author author) {
// TODO Auto-generated method stub
Session session = null;
Author a = null;
try {
session = sessionFactory.openSession();
String hql = "from Author where name =:name and password =:password";
Query query = session.createQuery(hql);
query.setString("name", author.getName());
query.setString("password", author.getPassword());
a = (Author) query.uniqueResult();
} catch (Exception e) {
// TODO: handle exception
e.printStackTrace();
} finally {
if(session!=null) {
session.close();
}
}
return a;
}
}
AuthorService:
public interface AuthorService {
public Author getAuthorByName(Author author);
}
AuthorServiceImpl:
@Component("authorServiceImpl")//把authorServiceImpl实例化到spring容器中
public class AuthorServiceImpl implements AuthorService{
private AuthorDao authorDao;
@Resource(name="authorDaoImpl")
public void setAuthorDao(AuthorDao authorDao) {
this.authorDao = authorDao;
}
@Override
public Author getAuthorByName(Author author) {
// TODO Auto-generated method stub
return authorDao.getAuthorByName(author);
}
}
LoginController:
@Controller
public class LoginController {
private AuthorService authorService;
@Resource(name="authorServiceImpl")//将authorServiceImpl实例化到spring容器中
public void setAuthorService(AuthorService authorService) {
this.authorService = authorService;
}
@RequestMapping(method=RequestMethod.GET,value="index")//定义一个请求路径
public String index() {
return "login";
}
@RequestMapping(method=RequestMethod.POST,value="login")
public ModelAndView AuthorLogin(@ModelAttribute ModelAndView mav,Author author) {
Author a1 = authorService.getAuthorByName(author);
if(a1!=null) {
mav.addObject(a1);
mav.setViewName("list");
}else {
mav.setViewName("redirect:index");
}
return mav;
}
}
第四步：配置spring—hibernacle.xml 文件：
1、先导入jdbc和log4j的properties文件
jdbc：
jdbc.driver = oracle.jdbc.driver.OracleDriver
jdbc.url = jdbc:oracle:thin:@localhost:1521:orcl
jdbc.username = scott
jdbc.password = sa
log4j：
log4j.rootLogger=info,a,b
log4j.appender.a=org.apache.log4j.ConsoleAppender
log4j.appender.a.Target=System.err
log4j.appender.a.layout=org.apache.log4j.SimpleLayout
log4j.appender.b = org.apache.log4j.FileAppender
log4j.appender.b.File = E:/gz.log
log4j.appender.b.layout = org.apache.log4j.PatternLayout
log4j.appender.b.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %l %F %p %m%n
spring—hibernacle.xml：
classpath:jdbc.properties
classpath:hbm/*.hbm.xml
hibernate.dialect=org.hibernate.dialect.OracleDialect
hibernate.hbm2ddl.auto = update
hibernate.show_sql =true
第五步：配置web.xml文件：
ssh
index.html
index.htm
index.jsp
default.html
default.htm
default.jsp
dispatcherServlet
org.springframework.web.servlet.DispatcherServlet
contextConfigLocation
classpath*:spring-mvc.xml
dispatcherServlet
*.html
org.springframework.web.context.ContextLoaderListener
contextConfigLocation
classpath*:spring-*.xml
jsp页面：
index.jsp
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
Insert title here
list.jsp
<%@ page language="java" contentType="text/html; charset=utf-8"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
Insert title here `在这里插入代码片`
${b.bookname}
login.jsp:
<%@ page language="java" contentType="text/html; charset=utf-8"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
Insert title here
