基于XML的SSM框架整合
根据学习,现在整理一下基于XML的SSM框架整合.
~~
1 首先是要创建一些素材
1.1 创建一个JavaWeb模块~~
1.2 创建一个我们使用的数据库(MySQL)
drop database if exists ssm;
create database ssm;
use ssm;
##创建图书表
create table t_book(
`id` int(11) primary key auto_increment, ## 主键
`name` varchar(50) not null, ## 书名
`author` varchar(50) not null, ## 作者
`price` decimal(11,2) not null, ## 价格
`sales` int(11) not null, ## 销量
`stock` int(11) ## 库存
);
## 插入初始化测试数据
insert into t_book(`id` , `name` , `author` , `price` , `sales` , `stock`)
values(null , 'java从入门到放弃' , '爱你哟' , 80 , 9999 , 9 );
1.3 然后在web工程下导入所需要的的所有jar包
如果你使用maven,这一段就可以自动跳过啦~
数据库连接池:
druid-1.1.9.jar
切入点表达式解析:
com.springsource.org.aspectj.weaver-1.6.8.RELEASE.jar
Junit测试包:
junit_4.12.jar
org.hamcrest.core_1.3.0.jar
Mybatis的jar包:
mybatis-3.5.1.jar
Mybatis整合Spring的包:
mybatis-spring-2.0.4.jar
mysql数据库驱动jar:
mysql-connector-java-5.1.37-bin.jar
Spring核心层包:
spring-beans-5.2.5.RELEASE.jar
spring-context-5.2.5.RELEASE.jar
spring-core-5.2.5.RELEASE.jar
spring-expression-5.2.5.RELEASE.jar
Spring的日记桥接包( 是核心包的依赖包必须导 ):
spring-jcl-5.2.5.RELEASE.jar
Spring切面包:
spring-aop-5.2.5.RELEASE.jar
spring-aspects-5.2.5.RELEASE.jar
Spring数据库访问以及事务:
spring-jdbc-5.2.5.RELEASE.jar
spring-orm-5.2.5.RELEASE.jar
spring-tx-5.2.5.RELEASE.jar
Spring的测试包:
spring-test-5.2.5.RELEASE.jar
SpringMVC需要的jar包:
spring-web-5.2.5.RELEASE.jar
spring-webmvc-5.2.5.RELEASE.jar
**
2 整合–配置文件
**
2.1在src目录下创建配置文件
具体文件名及目录如下
每个文件配置内容如下:
applicationContext.xml:
<?xml version="1.0" encoding="UTF-8"?>

-->
<!-- Mybatis整合Spring的核心配置之二 扫描并将Mapper接口注入到SpringIOC容器中 -->
<mybatis:scan base-package="com.csdn.mapper" />
<!-- 配置事务属性 -->
<tx:advice id="tx_ssm" transaction-manager="transactionManager">
<tx:attributes>
<tx:method name="add*" propagation="REQUIRED" />
<tx:method name="save*" propagation="REQUIRED" />
<tx:method name="update*" propagation="REQUIRED" />
<tx:method name="delete*" propagation="REQUIRED" />
<tx:method name="*" read-only="true" />
</tx:attributes>
</tx:advice>
<!-- 配置事务切面 -->
<aop:config>
<aop:advisor advice-ref="tx_ssm"
pointcut="execution(* com..service..*.*(..))" />
</aop:config>
</beans>
jdbc.properties文件:
user=root //这里不能使用username 会跟spring中默认的adminor冲突
password=root
url=jdbc:mysql://localhost:3306/ssm
driverClassName=com.mysql.jdbc.Driver
initialSize=5
maxActive=10
log4j.properties文件:
# Global logging configuration
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
mbg.xml文件:
这个文件在applicationContext中加入也可以,分开也可以.
<?xml version="1.0" encoding="UTF-8"?>
