框架篇：Spring+SpringMVC+hibernate整合开发

1、创建项目

一、新建一个空项目project 至关于eclipse的workspacecss

二、新建module至关于eclipse的projecthtml

File---New----Modulejava

2、项目完整目录：mysql

导包

不一样于以往的导包，因为咱们建立的是maven的webapp项目，因此如今只需配置下pomxml这个配置文件，系统会自动到maven的中央仓库去下载相应的包.web

本人的pom.xml配置文件以下（都写有说明的哈）： spring

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

OK，配置后运行下maven,就会自动向中央仓库下载相应的包啦！（这个就很少说了）。sql

3、SpringMVC配置

咱们先配置下SpringMVC的配置：resources/META-INF/spring-mvc.xml数据库

<?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.xsd
       http://www.springframework.org/schema/context
       http://www.springframework.org/schema/context/spring-context.xsd
       http://www.springframework.org/schema/mvc
       http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">

    <!-- 自动扫描该包，使SpringMVC认为包下用了@controller注解的类是控制器 -->
    <context:component-scan base-package="com.test.controller"/>

    <!-- 开启SpringMVC注解模式 -->
    <mvc:annotation-driven/>

    <!-- 静态资源默认servlet配置 -->
    <mvc:default-servlet-handler/>

    <!-- 定义跳转的文件的先后缀 ，视图模式配置-->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>
        <property name="prefix" value="/WEB-INF/views/"/>
        <property name="suffix" value=".jsp"/>
    </bean>


    <!-- 配置文件上传，若是没有使用文件上传能够不用配置，固然若是不配，那么配置文件中也没必要引入上传组件包 -->
    <bean id="multipartResolver"
          class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
        <!-- 默认编码 -->
        <property name="defaultEncoding" value="utf-8" />
        <!-- 文件大小最大值 -->
        <property name="maxUploadSize" value="10485760000" />
        <!-- 内存中的最大值 -->
        <property name="maxInMemorySize" value="40960" />
    </bean>


    <!-- 静态资源的处理 -->
    <!-- <mvc:resources mapping="/static/**" location="/static/" />-->
    <mvc:resources mapping="/js/**" location="/static/js/" />
    <mvc:resources mapping="/css/**" location="/static/css/" />
    <mvc:resources mapping="/images/**" location="/static/images/" />


</beans>

好了，咱们如今修改下web.xml这个配置文件，完善下SpringMVC的配置， web.xml配置以下：express

<?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_3_0.xsd"
         version="3.0">
  <!-- 地址为http://localhost:8080/  显示的默认网页-->
  <welcome-file-list>
    <welcome-file>/index.jsp</welcome-file>
  </welcome-file-list>

  <!--加载Spring的配置文件到上下文中去-->
  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>
      classpath:META-INF/applicationContext.xml
    </param-value>
  </context-param>

  <!-- spring MVC config start-->
  <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:META-INF/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 MVC config end-->


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

  <!--  字符集过滤  -->
  <filter>
    <filter-name>encodingFilter</filter-name>
    <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
    <init-param>
      <param-name>encoding</param-name>
      <param-value>UTF-8</param-value>
    </init-param>
    <init-param>
      <param-name>forceEncoding</param-name>
      <param-value>true</param-value>
    </init-param>
  </filter>
  <filter-mapping>
    <filter-name>encodingFilter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>

</web-app>

OK，SpringMVC配置完成，如今咱们进行一下测试吧apache

在controller层新建一个TestController，内容以下

package com.test.controller;

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

@Controller
@RequestMapping(value = "/test")
public class TestController {
    @RequestMapping(value = "/mvc")
    public String testMvc()
    {
        return "test";
    }
}

test.jsp网页以下：

<html>
<body>
<center>
<h2 style="color: #ff261a;">this is my test page!</h2>
</center>
</body>
</html>

重启Tomcat服务器，而后浏览器访问http://localhost/test/mvc以下图所示：

PS： Tomcat默认端口是8080，我更改了端口号，如若大家为更改，正确的访问地址是localhost：8080/test

OK，成功访问。

SpringMVC+Spring整合

这个就十分简单了，配置applicationContext.xml这个Spring的配置文件以下：

<?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:aop="http://www.springframework.org/schema/aop"

       xmlns:jdbc="http://www.springframework.org/schema/jdbc" xmlns:jee="http://www.springframework.org/schema/jee"

web.xml配置文件中更改了三处：引入Spring配置文件 Spring的监听器以及字符集过滤

OK，Spring+SpringMVC配置完成，下面咱们开始测试：

在service写一个TestServiceImpl实现TestService接口并实现其test()方法，代码以下：

yes，成功返回，说明咱们以前的配置没问题

Spring+SpringMVC+hibernate整合

好了，如今就缺hibernate这个框架了。。我先给你们看些我搭建好以后的结构图吧

咱们想来编写config.properties这个配置文件，里面存放的是hibernate的一些配置

#database connection config
jdbc.driver = com.mysql.jdbc.Driver
jdbc.url = jdbc:mysql://?????:3306/ssh?useUnicode=true&characterEncoding=utf-8
jdbc.username = root
jdbc.password = ???

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

这里链接数据库的参数因为我是链接我晚上的数据库，所以我数据库地址和密码打了“？？？”,大家链接时改为本身本地的就OK了
