hj_ssm

SSM(Spring+SpringMVC+MyBatis)框架集由Spring、MyBatis两个开源框架整合而成(SpringMVC是Spring中的部分内容).常作为数据源较简单的web项目的框架.

框架整合也主要是spring+mybatis整合,springmvc+mybaits整合.ssm是一个标准经典的mvc设计.

spring整合mybatis:

jdbc.properties<UTF-8>

driver=com.mysql.jdbc.Driver
url=jdbc:mysql://1127.0.0.1:3306/db_hj
username=root
password=123456
#定义初始连接数
initialSize=1
#定义最大连接数
maxActive=10
#定义最大空闲
maxIdle=8
#定义最小空闲
minIdle=1
#定义最长等待时间
maxWait=60000

配置日志文件log4j.properties

# LOG输出级别 debug,info,warn,error,fatal
log4j.rootLogger=INFO,Console,File
#定义日志输出目的地为控制台
log4j.appender.Console=org.apache.log4j.ConsoleAppender
log4j.appender.Console.Target=System.out
#灵活配置日志输出格式,下面一行是指定具体的格式
log4j.appender.Console.layout = org.apache.log4j.PatternLayout
log4j.appender.Console.layout.ConversionPattern=[%c] - %m%n

#文件大小到达指定尺寸的时候产生一个新的文件
log4j.appender.File = org.apache.log4j.RollingFileAppender
#指定输出目录
log4j.appender.File.File = logs/hj.log
#定义文件最大大小
log4j.appender.File.MaxFileSize = 10MB
# 输出所有日志,如果换成DEBUG表示输出DEBUG以上级别日志
log4j.appender.File.Threshold = ALL
log4j.appender.File.layout = org.apache.log4j.PatternLayout
log4j.appender.File.layout.ConversionPattern =[%p] [%d{yyyy-MM-dd HH\:mm\:ss}][%c]%m%n

整合springmvc spring-mvc.xml

配置 web.xml

	</servlet-mapping>
	<welcome-file-list>
		<welcome-file>/index.jsp</welcome-file>
	</welcome-file-list>

</web-app>

ssm框架整合的配置文件大致就是这几个.内容什么的再调整即可.

综合:log4j.xml->web.xml(springContext监听器,springMVC核心过滤器,中文过滤器)

->spring配置文件(数据库连接,mybatis总配置文件,sessionFactory,事务,扫描注解,不扫描controller,sessionTemplate,转换器)

->mybatis映射文件 ->springMVC配置文件(扫描controller,不扫描service)

基本现在新项目不会再用到SSM,胡乱记下,纪念过往时光~

 

附注:可以使用 mybatis的ScriptRunner在springboot项目启动时就执行sql文件.  @PostConstruct 这个注解标注方法会执行一次.

SELECT
`table_name`
FROM
information_schema.TABLES
WHERE
TABLE_SCHEMA = ( SELECT DATABASE ( ) ) 查询所有的表名.
