老三老大框架整合的思路

框架整合思路

springmvc+mybaits的体系架构

spring将各层进行整治并

透过spring管理持久层的mapper(相当给dao接口)
通过spring管理事务层service,service中得以调用mapper接口。
spring进行作业控制。
经spring管理呈现层Controller,Controller中好调用service接口。
mapper、service、Controller都是javabean,可以由spring来进展统一管理。

第一步:整合dao层
mybatis和spring整合,通过spring管理mapper接口。
动用mapper的扫描器自动扫描mapper接口在spring中展开挂号。
第二步:整合service层
通过spring管理 service接口。
用安排方式拿service接口配置于spring配置文件被。
兑现工作控制。
第三步:整合springmvc
由springmvc是spring的模块,不需要结合。

1、Dao层:

所需的jar包

mysql数据库让包:
mybatis的jar包
mybatis和spring整合包
log4j包
druid数据库连接池包
spring所有jar包(4.x搭配jdk8,3.x搭配jdk7)
jstl包

Mybatis的部署文件:SqlMapConfig.xml

匪需要安排外内容,需要出文件头。文件要在。

整合dao

数据库服务器配置文件
在classpath下创建db.properties

#配置信息采取name = value的形式

#1.配置驱动程序
jdbc.driver =com.mysql.jdbc.Driver

#2.配置数据库url
jdbc.url = jdbc:mysql://localhost:3306/coder_school?useUnicode=true&characterEncoding=UTF-8

#3.配置用户名
jdbc.username=root

#4.配置用户密码
jdbc.password=root

日记配置文件
在classpath下创建log4j.properties

# Global logging configuration
#\u751F\u4EA7\u73AF\u5883\u914D\u7F6Einfo   ERROR
log4j.rootLogger=DEBUG,stdout
# MyBatis logging configuration...
log4j.logger.org.mybatis.example.BlogMapper=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

Mybatis配置文件
在classpath下创建mybatis/SqlMapConfig.xml

<?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">
<configuration>
    <typeAliases>
        <package name="school.coder.domain"></package>
    </typeAliases>
</configuration>

spring管理SqlSessionFactory、mapper
在classpath下创建spring/ applicationContext-dao.xml
安排数据源

applicationContext-dao.xml:

整合service

Spring管理service bean,并开展作业控制
定义service接口

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc"

<!--     <bean id="ibs" class="com.neusoft.service.impl.AccountServiceImpl"/>
    <bean id="ius" class="com.neusoft.service.impl.UserServiceImpl"/> -->

以applicationContext-transaction.xml中使spring声明式事务控制方法

        http://www.springframework.org/schema/tx 
        http://www.springframework.org/schema/tx/spring-tx-4.0.xsd ">

<!-- 事务管理器 
    对mybatis操作数据库事务控制,spring使用jdbc的事务控制类
-->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource"/>
    </bean>

    <tx:annotation-driven transaction-manager="transactionManager"></tx:annotation-driven>

</beans>

测试service,在章程实现上上加 @Transactional注解测试工作是否见效。

老三老框架整合了,编写测试程序验证。

mybatis整合spring,通过由spring创建数据库连接池,spring管理SqlSessionFactory、mapper代理对象。需要mybatis和spring的整合包。

2、Service层:

applicationContext-service.xml:

具备的service实现类都放至spring容器中管理。并出于spring管理作业。

 

3、表现层:

Springmvc框架,由springmvc管理controller。

Springmvc的老三死组件。

(1)使用maven管理jar包
(这间除了ssm框架的jar包之外,其他的可依据需要选择去)

(3)在web.xml中布局spring监听,加载spring配置文件

布局springmvc前端控制器,拦截请求

        <param-value>classpath:spring/applicationContext*.xml</param-value>
    </context-param>
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

    <!-- 解决post乱码 -->
    <filter>
        <filter-name>CharacterEncodingFilter</filter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
        <init-param>

        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>CharacterEncodingFilter</filter-name>
        <url-pattern>/*</url-pattern>

    <!-- springmvc的前端控制器 -->
    <servlet>
        <servlet-name>e3-manager</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <!-- contextConfigLocation不是必须的, 如果不配置contextConfigLocation, springmvc的配置文件默认在:WEB-INF/servlet的name+"-servlet.xml" -->
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:spring/springmvc.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
