SpringMVC+Spring+mybatis项目从零开始--Spring mybatis mysql配置实现

上一章我们把SSM项目结构已搭建(SSM框架web项目从零开始--分布式项目结构搭建)完毕,本章将实现Spring,mybatis,mysql等相关配置。

1.    外部架包依赖引入

外部依赖包引入可以根据相关包名从

网站:http://mvnrepository.com/

获取依赖引入语句结构。

SSM项目详细依赖包请见ssm-parent中的pom.xml文件。

1.1  spring框架依赖包引入

spring-context

spring-beans

spring-jdbc

spring aspects

spring-webmvc

1.2  spring-mybatis依赖包引入

mybatis

mybatis-spring

1.3  数据库依赖包引入

mysql-connector-java

druid

1.4  redis依赖包引入

jedis

1.5  web相关依赖包引入

jstl

servlet-api

jsp-api

Jackson-databind

1.6  其他日志和公共包依赖引入

slf4j-log4j12

junit

commons-langs

commons-io

2.    各项目间依赖关系以及架包引入

ssm-parent实现了所有外部依赖包引入

(1)ssm-commons 实现公共的组件,工具类等

(2)ssm-manager 实际业务管理工程,聚合工程,

其包含工程依赖(1)

(3)ssm-manager-pojo

(4)ssm-manager-mapper 依赖(3)

(5)ssm-manager-service  依赖(3,4)

(6)ssm-manager-controller 依赖(3,5)

3.    Spring简单介绍

Spring是一个开源框架,Spring是于2003年兴起的一个轻量级的Java开发框架,由Rod Johnson创建。简单来说,Spring是一个分层的JavaSE/EEfull-stack(一站式) 轻量级开源框架。

轻量——从大小与开销两方面而言Spring都是轻量的。完整的Spring框架可以在一个大小只有1MB多的JAR文件里发布。并且Spring所需的处理开销也是微不足道的。此外,Spring是非侵入式的:典型地,Spring应用中的对象不依赖于Spring的特定类。

控制反转——Spring通过一种称作控制反转(IoC)的技术促进了低耦合。当应用了IoC,一个对象依赖的其它对象会通过被动的方式传递进来,而不是这个对象自己创建或者查找依赖对象。你可以认为IoC与JNDI相反——不是对象从容器中查找依赖,而是容器在对象初始化时不等对象请求就主动将依赖传递给它。

面向切面——Spring提供了面向切面编程的丰富支持,允许通过分离应用的业务逻辑与系统级服务(例如审计(auditing)和事务transaction)管理)进行内聚性的开发。应用对象只实现它们应该做的——完成业务逻辑——仅此而已。它们并不负责(甚至是意识)其它的系统级关注点,例如日志或事务支持。

容器——Spring包含并管理应用对象的配置和生命周期,在这个意义上它是一种容器,你可以配置你的每个bean如何被创建——基于一个可配置原型(prototype),你的bean可以创建一个单独的实例或者每次需要时都生成一个新的实例——以及它们是如何相互关联的。然而,Spring不应该被混同于传统的重量级的EJB容器,它们经常是庞大与笨重的,难以使用。

框架——Spring可以将简单的组件配置、组合成为复杂的应用。在Spring中,应用对象被声明式地组合,典型地是在一个XML文件里。Spring也提供了很多基础功能(事务管理、持久化框架集成等等),将应用逻辑的开发留给了你。

MVC——Spring的作用是整合,但不仅仅限于整合,Spring框架可以被看做是一个企业解决方案级别的框架。客户端发送请求,服务器控制器(由DispatcherServlet实现的)完成请求的转发,控制器调用一个用于映射的类HandlerMapping,该类用于将请求映射到对应的处理器来处理请求。HandlerMapping将请求映射到对应的处理器Controller(相当于Action)在Spring当中如果写一些处理器组件,一般实现Controller接口,在Controller中就可以调用一些Service或DAO来进行数据操作 ModelAndView用于存放从DAO中取出的数据,还可以存放响应视图的一些数据。如果想将处理结果返回给用户,那么在Spring框架中还提供一个视图组件ViewResolver,该组件根据Controller返回的标示,找到对应的视图,将响应response返回给用户。

所有Spring的这些特征使你能够编写更干净、更可管理、并且更易于测试的代码。它们也为Spring中的各种模块提供了基础支持。

--摘自百度百科

总结几点:

1)   spring是轻量级的,而且是开发源码的。

2)   spring有控制反转和依赖注入的特性,将类之间的主动关联转换为被动关联,实现的相互间的解耦,通过配置文件,简化了开发;

3)   aop面向切面编程,将系统核心业务与服务分离,实现了代码的解耦,通过切面实现全局调用,如日志,事务等;

4)   与其他框架能很好的集成,如mybatis,struts2,hibernate,redis等。

详情见官网:  http://spring.io/

4.    mybatis简单介绍

MyBatis是支持定制化 SQL、存储过程以及高级映射的优秀的持久层框架。MyBatis避免了几乎所有的 JDBC代码和手动设置参数以及获取结果集。MyBatis可以对配置和原生Map使用简单的 XML或注解,将接口和Java的 POJOs(Plain Old Java Objects,普通的 Java对象)映射成数据库中的记录。

详情见官网:http://www.mybatis.org/mybatis-3/zh/index.html

mybatis相对hibernate优势

1)   mybatis是轻量级的,学习成本较低,易上手;

2)   mybatis是半自动化的,相关的sql需要手动实现;

mybatis工作原理:

5.    Spring,mybatis,mysql等配置实现

由于SSM项目中ssm-controller依赖所有模块,为了方便配置文件易于管理,一般将项目的配置文件统一放置于smm-controller目录文件。

5.1  ssm-manager-controller项目中的所有配置文件

SpringMVC+Spring+mybatis项目从零开始--Spring mybatis mysql配置实现

db.properties

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://127.0.0.1:3306/ussm?characterEncoding=utf-8
jdbc.username=root
jdbc.password=root

log4j.pertites

#log4j.rootLogger=DEBUG,INFO,Console,ERROR,stdout
log4j.rootLogger=INFO,Console,ERROR,stdout # Druid

8.    总结

本章我们讲解了SSM项目中配置各项目pom文件、spring的事务、springaop、mybatis等配置。

代码路径(待确定):

mysql创建语句:

*/ SET FOREIGN_KEY_CHECKS=0; -- ----------------------------
-- Table structure for t_user

DROP TABLE IF EXISTS `t_user`;
CREATE TABLE `t_user` (
`id` int(32) NOT NULL,
`userName` varchar(255) DEFAULT NULL,

-- Records of t_user
-- ----------------------------
INSERT INTO `t_user` VALUES ('', 'liuren', '');
INSERT INTO `t_user` VALUES ('', 'lisi', '');
INSERT INTO `t_user` VALUES ('', 'lisi', '');
