篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了SSM相关的知识,希望对你有一定的参考价值。

1. 项目环境准备

1.1. 技术选型

整个项目使用的SSM框架 SpringMVCSpringMyBatismysql数据库,Shiro安全框架

 

1.2. 使用Maven创建Web项目

 

1.3. 引入maven项目pom文件依赖的和插件配置

Mavenpom文件集成了整个项目所需要的绝大部分框架依赖,后期其他依赖在实际开发中按需引入集合

2. 框架集成配置

整个框架的 SpringSpringMVC采用 xml方式配置(也可以自定义使用注解配置),

所以需要创建准备对应的xml配置文件

spring.xml

Spring框架的主配置文件,主要

springmvc.xml

SpringMVC配置文件

db.properties

数据库连接配置文件

log4j.properties

Log4j日志配置文件

其他配置文件后面使用到按需配置

使用Web项目,需要将框架位置到web.xml中才能生效

 

2.1. spring.xml文件配置

Spring.xml配置文件,主要配置spring注解配置包扫描组件位置,MyBatis代理对象创建

事务管理的配置

<?xml version="1.0" encoding="UTF-8"?>

<!-- 切面:切入点+通知 -->

<aop:advisor advice-ref="txAdvice" pointcut-ref="pt" />

</aop:config>

</beans>

 

2.2. springmvc.xml配置

Springmvc.xml主要配置一些springmvc框架相关配置,开启注解驱动,视图解析器,静态资源处理等等

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"

xmlns:context="http://www.springframework.org/schema/context"

xmlns:mvc="http://www.springframework.org/schema/mvc"

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

        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.xsd

        ">

 

<!-- 开启SpringMVC的注解驱动 -->

<mvc:annotation-driven />

 

 

<!-- 配置视图解析器 -->

<bean

class="org.springframework.web.servlet.view.InternalResourceViewResolver">

 

<property name="prefix" value="/WEB-INF/view/" />

 

<property name="suffix" value=".jsp"></property>

 

</bean>

 

<!-- 支持静态资源处理 -->

<mvc:default-servlet-handler/>

 

 

</beans>

 

2.3. db.properties配置文件

数据库连接配置文件

jdbc.driverClassName=com.mysql.jdbc.Driver

jdbc.url=jdbc:mysql://localhost:3306/logistics?characterEncoding=utf-8

jdbc.username=root

jdbc.password=root

jdbc.maxActive=10

2.4. log4j.properties日志配置文件

# Global logging configuration

log4j.rootLogger=ERROR, stdout

# MyBatis logging configuration...

log4j.logger.cn.zj.logistics=TRACE

# Console output...

log4j.appender.stdout=org.apache.log4j.ConsoleAppender

log4j.appender.stdout.layout=org.apache.log4j.PatternLayout

log4j.appender.stdout.layout.ConversionPattern=%5p [%t] - %m%n

 

2.5. web.xml

Web.xml作为动态web项目的入口文件,springspringmvc框架集成相关配置需要放到在此文件下配置

<?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">

 

 <!-- 配置spring的授权过滤器,让spring来管理shiro框架 -->

 <filter>

  <filter-name>shiroFilter</filter-name>

  <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>

  <!-- 配置shirofilter的生命周期交给servlet管理 -->

  <init-param>

  <param-name>targetFilterLifecycle</param-name>

  <param-value>true</param-value>

  </init-param>

 </filter>

 <filter-mapping>

  <filter-name>shiroFilter</filter-name>

  <url-pattern>/*</url-pattern>

 </filter-mapping>

  

  <!--  字符编码过滤器 -->

  <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>

 

 

<!-- 1.配置SpringMVC的前端控制器(总控) -->

<servlet>

<servlet-name>MVC</servlet-name>

<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

<init-param>

<param-name>contextConfigLocation</param-name>

<param-value>classpath:spring*.xml</param-value>

</init-param>

<load-on-startup>1</load-on-startup>

</servlet>

 

<servlet-mapping>

<servlet-name>MVC</servlet-name>

<url-pattern>*.do</url-pattern>

</servlet-mapping>

 

 

<!-- 设置项目的欢迎页面 -->

   <welcome-file-list>

   <welcome-file>/login.jsp</welcome-file>

   </welcome-file-list>

</web-app>

1.1. Springmvc框架集成的测试

 

1.1.1. 新建一个AdminController

package cn.zj.logistic.controller;

 

import org.springframework.stereotype.Controller;

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

 

@Controller

@RequestMapping("/admin")

public class AdminController {

 

//后台用户列表显示页面

@RequestMapping("/adminPage.do")

public String adminPage() {

 

return "admin_list";

}

}

 

1.1.2. adminPage.jsp管理员操作jsp文件

因为springmvc框架配置了视图解析器,所有SpringMVC控制器请求默认都请求转发

WEB-INF/view 目录下面

WEB-INF目录下面新建一个view目录,在下面再创建一个 adminPage.jsp文件
