ssh框架搭建

1.搭建环境windows10+eclipse4.8+jdk1.8+maven

2.框架springMVC+spring+Hibernate

3.搭建步骤

1)首先创建maven项目

    file--new--other---maven-project

2)配置pom文件

spring-core  spring-context  spring-web  spring-webmvc  spring-orm   hibernate-core  hibernate-entitymanager   mysql-connector-java

3)创建对应的资源包 src/main/java   src/main/resources

4)添加配置文件

spring-mvc.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:p="http://www.springframework.org/schema/p"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.0.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">

<!-- 对web包中的所有类进行扫描，以完成Bean创建和自动依赖注入的功能 -->
<context:component-scan base-package="cn.temptation" />

<!-- 激活基于注解的配置 @RequestMapping, @ExceptionHandler,数据绑定 ,@NumberFormat ,

<mvc:annotation-driven />

<!-- 视图层配置 -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<!--配置JSTL表达式-->
<property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>
<!-- 前缀 -->
<property name="prefix" value="/WEB-INF/view/"/>
<!-- 后缀 -->
<property name="suffix" value=".jsp"/>
</bean>

<!-- 配置静态资源 -->
<mvc:resources location="/res/" mapping="/res/**"/>
</beans>

 

 

 spring.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans default-autowire="byName"

<!-- 对web包中的所有类进行扫描，以完成Bean创建和自动依赖注入的功能 -->
<context:component-scan base-package="cn.temptation" />

<!-- 数据源，BasicDataSource,commons-dbcp -->
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
<property name="driverClassName" value="com.mysql.jdbc.Driver" />

<property name="sessionFactory" ref="sessionFactory" />
</bean>

<tx:annotation-driven transaction-manager="transactionManager" />
</beans>

 4)修改web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
id="WebApp_ID" version="3.0">

<display-name>Archetype Created Web Application</display-name>

<!-- 配置spring容器 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring.xml</param-value>
</context-param>

<!-- 配置监听器 -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

<!-- 请求都交给DispatcherServlet处理 -->
<servlet>
<servlet-name>springmvc</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring-mvc.xml</param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>springmvc</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>

<!-- 增加中文乱码过滤器 -->
<filter>
<filter-name>CharacterEncodingFilter</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>CharacterEncodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

<!-- 清除jsp空格 -->
<jsp-config>
<jsp-property-group>
<url-pattern>*.jsp</url-pattern>
<trim-directive-whitespaces>true</trim-directive-whitespaces>
</jsp-property-group>
</jsp-config>

<!--<welcome-file-list>
<welcome-file>/view/login.jsp</welcome-file>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>-->

</web-app>

 

5）编写测试的控制层和逻辑层代码

LoginController

package cn.temptation.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

import cn.temptation.entity.User;
import cn.temptation.service.LoginService;

/**
* @version
* @time 2018-2-28 下午5:57:07
* @describe:控制器
*/
@Controller
// 注解为控制器
@RequestMapping(value = "/login")
// 截获带有/login的请求
public class LoginController {
@Autowired
LoginService loginService; // 注入service层

@RequestMapping(method = RequestMethod.GET)
public String get() { // 用来返回一个页面
return "login"; // 返回指向login.jsp页面
}

@RequestMapping(method = RequestMethod.POST)
public String post(User user) { // 用来处理用户的登陆请求
if (loginService.login(user.getUserName(), user.getPassword()) == 1) {
return "login_success"; // 登陆成功，跳转到login_success.jsp页面
}
return "login";

}
}

 

LoginService

package cn.temptation.service;

public interface LoginService {
public int login(String userName, String password);
}

LoginServiceImpl

package cn.temptation.service;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import cn.temptation.dao.UserDao;

@Service
public class LoginServiceImpl implements LoginService {
@Autowired
private UserDao userDao;

@Override
public int login(String userName, String password) {
return userDao.find(userName, password) == null ? 0 : 1;
}

}

UserDao

package cn.temptation.dao;

import cn.temptation.entity.User;

public interface UserDao {
public User find(String userName, String password);
}

UserDaoImpl

package cn.temptation.dao;

import java.util.List;

import javax.annotation.Resource;

import org.hibernate.SessionFactory;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;
import org.springframework.stereotype.Repository;

import cn.temptation.entity.User;

@Repository
public class UserDaompl extends HibernateDaoSupport implements UserDao {

// 用来注入sessionFactory（不注入会报错）
@Resource(name = "sessionFactory")
public void setSessionFactoryOverride(SessionFactory sessionFactory) {
super.setSessionFactory(sessionFactory);
}

@Override
public User find(String userName, String password) {
List<?> users = getHibernateTemplate()
.find("from User where userName=? and password=?", userName,
password);
return users.size() > 0 ? (User) users.get(0) : null;// 通过Hibernate去数据库取
}

}

User

package cn.temptation.entity;

public class User {
private Integer id;
private String userName;
private String password;

public Integer getId() {
return id;
}

public void setId(Integer id) {
this.id = id;
}

public String getUserName() {
return userName;
}

public void setUserName(String userName) {
this.userName = userName;
}

public String getPassword() {
return password;
}

public void setPassword(String password) {
this.password = password;
}

@Override
public String toString() {
return "User [id=" + id + ", userName=" + userName + ", password="
+ password + "]";
}

}

User.hbm.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd" >
<hibernate-mapping package="cn.temptation.entity">
<class name="User" table="user">
<id name="id">
<generator class="native"/>
</id>
<property name="userName" length="12" not-null="true" unique="true"/>
<property name="password" length="12" not-null="true"/>
</class>
</hibernate-mapping>

6)编写视图层的jsp代码

在webapp下创建新的文件夹view将测试的登录和登录成功的jsp放到这个文件夹下

login.jsp

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd" >
<hibernate-mapping package="cn.temptation.entity">
<class name="User" table="user">
<id name="id">
<generator class="native"/>
</id>
<property name="userName" length="12" not-null="true" unique="true"/>
<property name="password" length="12" not-null="true"/>
</class>
</hibernate-mapping>

 login-success.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>登陆成功</title>
</head>
<body>
登陆成功
</body>
</html>

 7)项目部署到tomcat中启动服务
