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 ,
@datetimeformat ,@controller ,@valid ,@requestbody ,@responsebody等 -->
<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"
xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/xmlschema-instance"

<!-- 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="url" value="jdbc:mysql://localhost:3306/ket-test?useunicode=true&amp;characterencoding=utf-8" />

<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
