SSM整合案例

SSM项目编程思路

项目准备

1、 分析需求，根据需求创建相应数据库 （基本sql语句）
​
2、 创建Maven项目，配置pom.xml，导入相应jar包 （mvn仓库），需要再Artifacts手动创建lib目录将jar包部署
​
3、 根据数据库创建相应pojo，搭建日志环境Log4j   （Book lombok插件 log4j.properties）

Dao层

4、 根据业务需求创建接口，编写增删改查的方法  （BookMapper）
​
5、 编写BookMapper.xml配置文件，编写sql语句，实现BookMapper接口中的功能。 （BookMapper.xml）
​
6、 编写mybatis-config.xml配置文件，设置别名、绑定mapper等  （mybatis.xml）
​
7、 编写spring-dao.xml配置文件，创建sqlSession，有多种方法，本案例采用继承SqlSessionDaoSupport，
    给BookMapperImpl注入sqlSessionFactory，dataSource也有多种方法，c3p0/druid/spring-jdbc等，
    本案例采用spring-jdbc，另外将pojo类交由spring-dao管理 （spring-dao.xml）
    
8、 编写BookMapper接口实现类，用java实现BookMapper.xml中的sql （BookMapperImpl.xml）

Service层

9、 编写BookService接口，写入需要实现的业务 （BookService）
​
10、编写BookService实现类，实现方法，此处需要组合BookMapper （BookServiceImpl）
​
11、编写spring-service.xml，并将service层类交由其管理，此处需要注入BookMapper，
    @Resource先根据名字注入，不匹配再按照类型注入，@Autowire那类型注入，可以和@Qualifier搭配使用 （spring-service.xml）

Controller层

12、编写web.xml配置DispatcherServlet和CharacterEncodingFilter，后者主要解决前端与后端的数据乱码问题，
    DispatcherServlet主要用作职责调度工作，本身主要用于控制流程，主要职责如下：
​
①、文件上传解析，如果请求类型是multipart将通过MultipartResolver进行文件上传解析；
​
②、通过HandlerMapping，将请求映射到处理器（返回一个HandlerExecutionChain，它包括一个处理器、多个HandlerInterceptor拦截器）；
​
③、通过HandlerAdapter支持多种类型的处理器(HandlerExecutionChain中的处理器)；
​
④、通过ViewResolver解析逻辑视图名到具体视图实现；
​
⑤、本地化解析；
​
⑥、渲染具体的视图等；
​
⑦、如果执行过程中遇到异常将交给HandlerExceptionResolver来解析。  （web.xml）
​
13、编写spring-mvc.xml配置视图层InternalViewResolver，注入前缀后缀，开启扫描注解context和mvn的均要开启以及开启对静态资源的访问。 （spring-mvc.xml）
​
14、编写Controller通过@Controller和return “页面名称”以及@RequestMapping实现对页面的访问，此外需要注入bookService，
    同上，可以通过@Resource、@Autowire和@Qualifier搭配使用实现注入。 （Controller）
  
15、根据业务内容去编写前端页面，可以参考***Bootstrao可视化系统***
    
16、配置Tomcat服务器，fix项目的Artifacts即可。

SSM环境搭建

SQL

CREATE DATABASE `ssmbuild`;
​
USE `ssmbuild`;
​
DROP TABLE IF EXISTS `books`;
​
CREATE TABLE `books` (
                         `bookID` INT(10) NOT NULL AUTO_INCREMENT COMMENT '书id',
                         `bookName` VARCHAR(100) NOT NULL COMMENT '书名',
                         `bookCounts` INT(11) NOT NULL COMMENT '数量',
                         `detail` VARCHAR(200) NOT NULL COMMENT '描述',
                         KEY `bookID` (`bookID`)
) ENGINE=INNODB DEFAULT CHARSET=utf8
​
INSERT  INTO `books`(`bookID`,`bookName`,`bookCounts`,`detail`)VALUES 
(1,'Java',1,'从入门到放弃'),
(2,'MySQL',10,'从删库到跑路'),
(3,'Linux',5,'从进门到进牢');

注意小细节

① 给工程Artifacts添加lib目录将包导入
② 项目的默认maven版本要进行修改
③ tomcat配置时，无需其他操作，fix模块就行
④ 配置DispatcherServlet的初始参数时，文件应选择applicationContext.xml，不选择spring-mvc.xml
⑤ 前端页面传回对象的属性时，Controller层可以用对象接收，字段名不匹配时则为空。
⑥ BeanCreateException出现在sqlSessionFactory时，尝试把数据库连接工作交给mybatis-config.xml管理，
  就避开了sqlSessionFactory问题了。(参考如下xml文件)
待补充。。。

mybatis-config.xml （管理数据库连接）

<?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>

    <environments default="development">
        <environment id="development">
            <transactionManager type="JDBC"/>
            <dataSource type="POOLED">
                <property name="driver" value="com.mysql.jdbc.Driver"/>

    </environments>
    <mappers>
        <mapper resource="com/beal/dao/BookMapper.xml"/>
    </mappers>

</configuration>

spring-dao.xml (不管理dataSource)
