SSH

介绍:
SSH即struts+spring+hibernate的一个集成框架他们各自是
struts:控制器 spring:调度 hibernate:操作数据库
SSH框架从业务逻辑上分为四层:

Dao层:数据访问层:使用hibernate链接数据库(增删改查)操作
配置:在spring的配置中进行文件配置

Service层:业务逻辑层:负责业务模块的设计逻辑,设计接口，再设计实现的类
配置:在spring的配置中进行配置

Controller层:控制器层:调用Service层的接口来控制业务流程。
配置:在spring的配置中进行配置

View层:表现层:与Controller层紧密联系,主要负责前端jsp页面展示.

开整:是在eclipse上的简单的项目:
1:建一个maven项目:**

 

完成以后点Finish
建成功以后他会报错那是没有web.xml文件,步骤如下:
单击选中项目右键如下图:

2.接下来配置一下tomcat:

 

 

 

 

3.配置pom.xml文件,数据库是mysql

4.配置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" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" version="2.5">

  <welcome-file-list>
    <welcome-file>index.html</welcome-file>
    <welcome-file>index.htm</welcome-file>
    <welcome-file>index.jsp</welcome-file>
    <welcome-file>default.html</welcome-file>
    <welcome-file>default.htm</welcome-file>
    <welcome-file>default.jsp</welcome-file>
  </welcome-file-list>
  
         <servlet>
            <servlet-name>spring</servlet-name>
            <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
            <init-param>
              <param-name>contextConfigLocation</param-name>
              <!-- 此处指向的的是SpringMVC的配置文件 -->
              <param-value>classpath:spring-mvc.xml</param-value>
            </init-param>
            <!--配置容器在启动的时候就加载这个servlet并实例化-->
            <load-on-startup>1</load-on-startup>
        </servlet>

        <servlet-mapping>
            <servlet-name>spring</servlet-name>
            <url-pattern>/</url-pattern>
        </servlet-mapping>
        
        <!-- Spring监听器 -->
        <listener>
            <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
        </listener>

        <!--  字符集过滤  -->
        <filter>

            <param-value>classpath:spring-hibernate.xml</param-value>
        </context-param>
</web-app>

 
5.springMVC配置

<mvc:annotation-driven />
    <context:component-scan
        base-package="com.zhiyou100" />
    <!-- 对模型视图名称的解析,在请求时模型视图名称添加前后缀 -->
    <bean id="viewResolver"
        class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="viewClass"
            value="org.springframework.web.servlet.view.JstlView" />
        <!-- 前缀 -->
        <property name="prefix" value="view/" />
        <!-- 后缀 -->
        <property name="suffix" value=".jsp" />
    </bean>

    <!--这里是对静态资源的映射 -->
    <mvc:resources mapping="/js/**" location="/resources/js/" />
    <mvc:resources mapping="/css/**"
        location="/resources/css/" />
    <mvc:resources mapping="/img/**"
        location="/resources/img/" />

</beans>

    <mvc:resources mapping="/css/**"
        location="/resources/css/" />
    <mvc:resources mapping="/img/**"
        location="/resources/img/" />

</beans>

需要修改一下你自己的包名

6.配置spring-hibernate:文件名称:spring_hibernate.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: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-4.1.xsd
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context-4.1.xsd
        http://www.springframework.org/schema/mvc
        http://www.springframework.org/schema/mvc/spring-mvc-4.1.xsd">
        
          <!--********************************************配置Spring***************************************-->
        <!-- 自动扫描 -->
        <context:component-scan base-package="com.zy">
            <!-- 扫描时跳过 @Controller 注解的JAVA类（控制器） -->
            <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
        </context:component-scan>


    <!--********************************************配置hibernate********************************************-->

    <!--扫描配置文件(这里指向的是之前配置的那个config.properties)-->
    <context:property-placeholder location="classpath:/db.properties" />

    <!--配置数据源-->
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close">
        <property name="driverClass" value="${jdbc.driver}" />  <!--数据库连接驱动-->
        <property name="jdbcUrl" value="${jdbc.url}" />     <!--数据库地址-->
        <property name="user" value="${jdbc.username}" />   <!--用户名-->
        <property name="password" value="${jdbc.password}" />   <!--密码-->
        <property name="maxPoolSize" value="40" />      <!--最大连接数-->
        <property name="minPoolSize" value="1" />       <!--最小连接数-->
        <property name="initialPoolSize" value="10" />      <!--初始化连接池内的数据库连接-->
        <property name="maxIdleTime" value="20" />  <!--最大空闲时间-->
    </bean>

    <!--配置session工厂-->
    <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
        <property name="dataSource" ref="dataSource" />
        <property name="packagesToScan" value="com.zy.pojo" />
        <property name="hibernateProperties">
            <props>
                <prop key="hibernate.hbm2ddl.auto">${hibernate.hbm2ddl.auto}</prop> <!--hibernate根据实体自动生成数据库表-->
                <prop key="hibernate.dialect">${hibernate.dialect}</prop>   <!--指定数据库方言-->
                <prop key="hibernate.show_sql">${hibernate.show_sql}</prop>     <!--在控制台显示执行的数据库操作语句-->
                <prop key="hibernate.format_sql">${hibernate.format_sql}</prop>     <!--在控制台显示执行的数据哭操作语句（格式）-->
            </props>
        </property>
    </bean>

    <!-- 事物管理器配置  -->
    <bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
        <property name="sessionFactory" ref="sessionFactory" />
    </bean>

</beans>

注意:里面需要修改包名,在session工厂,还有在spring自动扫描:

7.创建db.property文件:

#database connection config
jdbc.driver = com.mysql.jdbc.Driver
jdbc.url = jdbc:mysql:///ssm?useUnicode=true&characterEncoding=utf-8
jdbc.username = root
jdbc.password = 123456

#hibernate config
hibernate.dialect = org.hibernate.dialect.MySQLDialect
hibernate.show_sql = true
hibernate.format_sql = true
hibernate.hbm2ddl.auto = update

注意:需要修改数据库密码,名称

8.日志配置log4j.properties

### direct log messages to stdout ###
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.err
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n
 
### direct messages to file mylog.log ###
log4j.appender.file=org.apache.log4j.FileAppender
log4j.appender.file.File=c:mylog.log
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n
 
### set log levels - for more verbose logging change 'info' to 'debug' ###
 
log4j.rootLogger=DEBUG, stdout

9.开始建包建层

9.1先建View层一个展示页面:

<%@ 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>Insert title here</title>
</head>
<body>
<center>
<h2 style="color: #ff261a;">this is my test page!</h2>
</center>
</body>
</html>

9.2 建Controller层

package com.zy.controller;

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

@Controller
public class UserController {

}

9.3 dao层和pojo实体类层
9.3.1 dao层

package com.zy.dao;

public interface UserDao {

}

9.3.2 实体类

package com.zy.pojo;

public class User {

}

9.4 Service层和实现类

9.4.1service层

package com.zy.service;

public interface UserService {

}

9.4.2 实现类,实现UserService

package com.zy.service.imp;

import org.springframework.stereotype.Service;

import com.zy.service.UserService;

@Service
public class UserServiceImp implements UserService{

}
