ssm框架搭建之ss框架

很早就有写点博客的想法了，却一直没有实施。这个是我的第一篇博客，就从ssm框架的搭建开始吧。

因时间仓促所以先纪录下搭建ss的，后期再逐渐完善，虽然没有对数据的操作，但是项目基本是可以正常跑起来了。

一开发环境：
jdk1.8;tomcat8;idea;maven

二开发过程
1 创建项目
使用idea开发工具创建的一个maven项目。
2 项目结构（见附件）
src

|-- filters （主要是一些环境配置文件，比如一些数据库的参数配置等等）

|-- dev.properties

|-- test.properties

|-- main

|-- java

|-- FirstDemo

|-- controller

|--test

|--dao

|--server

|-- resources （资源配置文件）

|-- dubbo

|-- spring

|-- applicationContext.xml

|-- spring-dal-mysql.xml

|--spring-mvc.xml

|-- webapp

|-- WEB-INF

|-- view

|-- hello.html

|-- web.xml

|-- index.jsp

4 web.xml文件的配置

ps：只是一些简单配置，如果项目全面还需要添加一些过滤器啊等等配置，每个配置都有对应的注释

<!--加载spring的配置，主要是spring的配置文件，当然也可以在启动的时候加载其他的配置文件入spring容器-->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:spring/applicationContext.xml</param-value>
    </context-param>
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

    <!--配置servlet拦截器，springmvc框架的配置文件-->
    <servlet>
       <servlet-name>springWeb</servlet-name>
       <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:spring/spring-mvc.xml</param-value>
        </init-param>
        <!--容器启动的优先级，正整数值越小，优先级越高，相同则按顺序加载-->
        <load-on-startup>1</load-on-startup>
    </servlet>
   <!--设定需要拦截的url-->
    <servlet-mapping>
        <servlet-name>springWeb</servlet-name>
        <url-pattern>*.do</url-pattern>
    </servlet-mapping>
    <servlet-mapping>
        <servlet-name>springWeb</servlet-name>
        <url-pattern>*.action</url-pattern>
    </servlet-mapping>

    <!--过滤页面字符编码-->
    <filter>
      <filter-name>characterEncodingFilter</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>
    </filter>
    <filter-mapping>
        <filter-name>characterEncodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

5 资源配置文件

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

   <!--配置视图文件地方-->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/view/"/>
        <property name="suffix" value=".html"/>
    </bean>
    </beans>

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

	http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd"
       default-lazy-init="true">

    <!--扫描包-->
    <context:component-scan base-package="FirstDemo"/>
    <aop:aspectj-autoproxy expose-proxy="true"/>
    <!--注解驱动-->
    <mvc:annotation-driven/>
    <!--开启哪个数据库连接包下的事务-->
    <!-- <tx:annotation-driven transaction-manager="channelTansactionManager" proxy-target-class="true" />-->

    <!--可以通过import引用一些别的资源配置文件..比如专门数据源的等等-->
    <!--<import resource="spring-mvc.xml"/>-->
   <!-- <import resource="spring-dal-mysql.xml"></import>-->
</beans>

6 以上差不多就可以简单的跑起来了，看下效果吧

7 当然好像还忘了点什么，就是controller中的一点东西

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

/**
 * Created by sunholdIng on 2017/1/12.
 */
@Controller
@RequestMapping(value = "/hello")
public class test {

    @RequestMapping(value = "/hello")
    public String hello(){
        return "hello";
    }
}
