一个简单的ssm框架的搭建

简单的ssm框架的搭建和配置文件

ssm框架里边的配置：

1.src路径下直接存放数据库和log4j的properties文件

2.src路径下建个config包，分别放置ssm的xml文件

3.修改WEB-INF路径下的web.xml

4.注意放置配置文件的路径问题

1.src路径下的jdbc.propreties和log4j.properties

log4j.properties

log4j.properties里边的代码，例如：

# Global logging configuration
log4j.rootLogger=DEBUG, stdout
# 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

jdbc.properties

jdbc.properties里边的代码，例如：

# Global logging configuration
jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql:///ssm_my?useUnicode=true&characterEncoding=utf8
jdbc.username=root
jdbc.password=root

2.src路径下建个config包，分别放置ssm的xml文件

applicationContext.xml

spring框架里边applicationContext.xml配置文件的代码，例如：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"

</context:component-scan>

<!-- 加载配置文件 -->
<context:property-placeholder location="classpath:jdbc.properties" />
<!-- 数据库的配置文件 -->
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
<property name="driverClassName" value="${jdbc.driverClassName}"></property>
<property name="url" value="${jdbc.url}"></property>
<property name="username" value="${jdbc.username}"></property>

</bean>

<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.offcn.mapper"></property>
</bean>

<bean id="transactionManager"
class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource"></property>
</bean>

<tx:advice id="txAdvice" transaction-manager="transactionManager">
<tx:attributes>
<tx:method name="find*" isolation="DEFAULT" propagation="REQUIRED"
read-only="true" />
<tx:method name="*" isolation="DEFAULT" propagation="REQUIRED"
read-only="false" />
</tx:attributes>
</tx:advice>
<!-- aop配置 -->
<aop:config>
<aop:pointcut expression="execution(* com.offcn.service.*.*(..))"
id="poit" />
<aop:advisor advice-ref="txAdvice" pointcut-ref="poit" />
</aop:config>
</beans>

springmvc-servlet.xml

springmvc框架里边springmvc-servlet.xml配置文件的代码，例如：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.3.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsd"> 
<bean
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="viewClass"
value="org.springframework.web.servlet.view.JstlView"></property>
<property name="prefix" value="/views/"></property>
<property name="suffix" value=".jsp"></property>
</bean>

<context:component-scan base-package="com.offcn.controller"></context:component-scan>
<mvc:annotation-driven>
</mvc:annotation-driven>
<mvc:default-servlet-handler />

<mvc:interceptors>
<mvc:interceptor>
<mvc:mapping path="/**" />
<bean class="com.offcn.interceptor.LoginInterceptor">
<property name="excuteMappingURL">
<list>
<value>.js</value>
<value>.css</value>
<value>.png</value>
<value>.gif</value>
<value>.jsp</value>

xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"> 
<display-name>ssm</display-name>

<welcome-file-list>
<welcome-file>views/login.jsp</welcome-file>
</welcome-file-list>

<!-- 解决字符乱码问题 -->
<filter>
<filter-name>CharacterEncodingFilter</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>utf-8</param-value>
</init-param>

</listener>

<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:config/applicationContext.xml</param-value>
</context-param>

</web-app>

4.注意放置配置文件的路径问题
