spring项目篇2----编写配置文件

我们接下来开始编写我们的权限系统，以便进一步熟悉SSM，接下来按照第一篇起一个maven项目，项目简介如下，接下来看一下配置文件 

 web.xml

DOCTYPE web-app PUBLIC
 "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
 "http://java.sun.com/dtd/web-app_2_3.dtd" >

<web-app xmlns="http://java.sun.com/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
                      http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
         version="3.0"
         metadata-complete="false">

接下来看一下spring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"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context https://www.springframework.org/schema/context/spring-context.xsd">
    
    <context:component-scan base-package="com.yang" />

    
    <import resource="classpath:application-mybatis" />

    
    <import resource="classpath:application-mvc.xml" />

beans>

数据库属性文件

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/promission?characterEncoding=utf-8
jdbc.username=root
jdbc.password=mysql

mybatis的配置文件

springMvc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"

sqlMapConfig

xml version="1.0" encoding="UTF-8" ?>
DOCTYPE configuration
        PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-config.dtd">

        <package name="com.yang.domain" />
    typeAliases>
    <plugins>
        
        <plugin interceptor="com.github.pagehelper.PageHelper" />
    plugins>

最后看一下可以根据数据库帮助我们生成mapper接口以及xml文件的插件的配置

xml version="1.0" encoding="UTF-8"?>
DOCTYPE generatorConfiguration
        PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"
        "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">

文件结尾，我们看一下maven的项目依赖
