SSM整合總結筆記-1（nf4slide項目筆記 ）

Spring

SpringMVC

分離控制器、模型對象、分派器以及處理程序對象的角色

配置springmvc-servlet.xml文件、配置web.xml文件

Mybatis

本爲ibatis。基於Java的持久層框架，（SQL  Maps 和DAO即Data Access Objects）。MyBatis 使用簡單的 XML或註解用於配置和原始映射，將接口和 Java 的POJOs（Plain Old Java Objects，普通的 Java對象）映射成數據庫中的記錄。（配置Mapping映射文件）

整合

• 配置spring-mvc-servlet.xml文件

• 配置web.xml文件，配置的spring-mvc的Servlet就是爲了完成SpringMVC+MAVEN的整合。
• Log4j:使用日誌來輸出信息 Log4j配置詳解

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee"

    <display-name>nf404</display-name>

    <welcome-file-list>
        <welcome-file>homeA.html</welcome-file>

        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:applicationContext.xml</param-value>

    <!--log4j配置-->

        <param-name>log4jConfigLocation</param-name>
        <param-value>classpath:log4j.properties</param-value>

 <!-- Spring監聽器 -->  
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

<!-- Spring MVC servlet --> 
    <servlet>

    <servlet-mapping>
        <servlet-name>dispatch</servlet-name>
        <url-pattern>/</url-pattern>

        <filter-name>characterEncodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
</web-app>

• 配置mybatis-config.xml文件

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

        "http://mybatis.org/dtd/mybatis-3-config.dtd">

            <dataSource type="POOLED">
                <!--maxActive: 最大連接數量-->
                <property name="maxActive" value="150"/>
                <!--minIdle: 最小空閒連接-->
                <property name="minIdle" value="5"/>

            </dataSource>
        </environment>
    </environments>
    <mappers>

• 設置db.properties文件

driver=com.mysql.jdbc.Driver
url = 
username = 
password =
