##Spring + MyBatis 整合 (收权)
###创建JDBC配置文件jdbc.properties和MyBatis配置文件mybatis-config.xml
在resources目录下建立JDBC配置文件jdbc.properties
配置内容，需要修改数据库名、用户名、密码
# 加载MySQL驱动类
jdbc.mysql.driver=com.mysql.jdbc.Driver
# 数据库访问路径
# useUnicode=true 启动编码格式
# characterEncoding=UTF-8 设置编码格式为UTF-8
# allowMultiQueries=true 设置MySQL允许执行多条SQL语句属性
jdbc.mysql.url=jdbc:mysql://127.0.0.1:3306/数据库名?useUnicode=true&characterEncoding=UTF-8&allowMultiQueries=true
# 数据库用户名
jdbc.mysql.username=用户名
# 数据库密码
jdbc.mysql.password=密码
#-----------------------------MySQL数据配置信息----------------------------------------#
#配置初始化大小、最小、最大
jdbc.initialSize = 3
jdbc.minIdle = 5
jdbc.maxActive = 20
#配置获取连接等待超时的时间
jdbc.maxWait = 60000
#配置间隔多久才进行一次检测，检测需要关闭的空闲连接，单位是毫秒
jdbc.timeBetweenEvictionRunsMillis = 60000
#配置一个连接在池中最小生存的时间，单位是毫秒
jdbc.minEvictableIdleTimeMillis = 300000
#测试代码
jdbc.validationQuery = SELECT 'x'
jdbc.testWhileIdle=true
jdbc.testOnBorrow=false
jdbc.testOnReturn=false
###收回连接数据源的权力
包括收回连接数据源的权力、收回创建SqlSessionFactory的权力、读取核心配置文件、读取映射文件的权力、事务管理器
配置beans.xml
<!-- 3.读取属性文件 -->
<context:property-placeholder location="classpath:jdbc.properties"/>
<!-- 4.配置数据源 -->
<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource" destroy-method="close">
<property name="driverClassName" value="${jdbc.mysql.driver}" />
<property name="url" value="${jdbc.mysql.url}" />
<property name="username" value="${jdbc.mysql.username}" />
<property name="password" value="${jdbc.mysql.password}" />
<!-- 配置初始化大小、最小、最大 -->
<property name="initialSize" value="3" />
<!-- 最大空闲时，当经过一个高峰之后，连接池可以将一些用不到的连接释放，一直减少到maxIdle为止 -->
<property name="minIdle" value="5" />
<!-- 连接池的最大值 -->
<property name="maxActive" value="20" />
<!-- 配置获取连接等待超时的时间 -->
<property name="maxWait" value="60000" />
<!-- 配置间隔多久才进行一次检测，检测需要关闭的空闲连接，单位是毫秒 -->
<property name="timeBetweenEvictionRunsMillis" value="60000" />
<!-- 配置一个连接在池中最小生存的时间，单位是毫秒 -->
<property name="minEvictableIdleTimeMillis" value="300000" />
<property name="validationQuery" value="SELECT 'x'" />
<property name="testWhileIdle" value="true" />
<property name="testOnBorrow" value="false" />
<property name="testOnReturn" value="false" />
</bean>
<!-- 5.创建SqlSession工厂和读取核心配置文件以及映射文件 -->
<bean id="sqlSessionFactoryBean" class="org.mybatis.spring.SqlSessionFactoryBean">
<!-- 配置数据源 -->
<property name="dataSource" ref="dataSource"/>
<!-- 配置读取核心配置文件 -->
<property name="configLocation" value="classpath:mybatis-config.xml"/>
<!-- 配置读取映射文件 -->
<property name="mapperLocations" value="classpath:com/gobha/**/model/*Mapper.xml"/>
</bean>
<!-- 6.动态创建接口实现类的工具类 sqlsession.getMapper方法 -->
<bean id="mapperScannerConfigurer" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<!-- 实现接口的位置 -->
<property name="basePackage">
<value>com.gobha.**.dao</value>
</property>
<!-- 注入的名字 -->
<property name="sqlSessionFactoryBeanName" value="sqlSessionFactoryBean"/>
<!-- 如果你想在接口使用注解 -->
<!-- <property name="annotationClass" value="org.springframework.stereotype.Repository"/> -->
</bean>
<!-- 7.配置事务管理器 -->
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource"/>
</bean>
<!-- 8.配置哪些方法需要使用事务管理器进行管理 -->
<tx:advice id="serviceAdvice" transaction-manager="transactionManager">
<tx:attributes>
<tx:method name="get*" read-only="true"/>
<tx:method name="load*" read-only="true"/>
<tx:method name="query*" read-only="true"/>
<tx:method name="list*" read-only="true"/>
<tx:method name="find*" read-only="true"/>
<tx:method name="sel*" read-only="true"/>
<tx:method name="login*" read-only="true"/>
<tx:method name="check*" read-only="true"/>
<tx:method name="valid*" read-only="true"/>
<tx:method name="*"/>
</tx:attributes>
</tx:advice>
<!-- 9.使用AOP告知是哪个层次下的方法被监控 -->
<aop:config proxy-target-class="true">
<aop:pointcut expression="execution(* com.gobha..service.*Service.*(..))" id="servicePointCut"/>
<aop:advisor advice-ref="serviceAdvice" pointcut-ref="servicePointCut"/>
</aop:config>
<!-- 10.注解版本的事务 -->
<tx:annotation-driven proxy-target-class="true"/>
如果报错缺少相应的class，就将缺少的class的jar包放入lib文件夹中，并build path可解决问题。（Druid和mysql-connector易出现问题）
###创建log4j配置文件log4j.properties
在resources目录下建立log4j配置文件log4j.properties
配置内容
#可以设置级别：trace>debug>info>warn>error
#debug：显示debug、info、error
#info：显示info、error
#error：只error
# Global logging configuration
log4j.rootLogger=INFO, stdout
# 配置命名控件的位置
log4j.logger.com.gobha.dao.UserDao=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
##配置其他重要内容
###完成springMVC.xml配置
配置JSP请求转发的视图解析器、配置静态资源的排除方案、配置文件上传的解析器、配置统一简单异常处理
<!-- 3.JSP请求转发的视图解析器 -->
<bean id="internalResourceViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<!-- 前缀 -->
<property name="prefix" value="/WEB-INF/"/>
<!-- 后缀 -->
<property name="suffix" value=".jsp"/>
<!-- JSTL视图 -->
<property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>
<!-- 排序 -->
<property name="order" value="10"/>
</bean>
<!-- 4.配置静态资源的排除方案,使用简单方式 -->
<mvc:default-servlet-handler default-servlet-name="default" />
<!-- 5.配置文件上传的解析器,需要注意ID问题 -->
<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
<!-- 文件上传的编码格式 -->
<property name="defaultEncoding" value="UTF-8" />
<!-- 配置文件上传的大小 -->
<property name="maxUploadSize" value="20971520" />
<!-- 配置文件上传缓存 -->
<property name="maxInMemorySize" value="2048" />
<!-- 配置文件上传的延迟操作，提高效率 -->
<property name="resolveLazily" value="true" />
</bean>
<!-- 6.配置统一简单异常处理,匹配的映射为RuntimeException/Exception,后续可以添加其他注解版本 -->
<bean id="simpleExceptionCacheResolver" class="org.springframework.web.servlet.handler.SimpleMappingExceptionResolver">
<property name="defaultErrorView" value="jsp/error" />
<property name="exceptionAttribute" value="ex" />
<property name="exceptionMappings">
<props>
<prop key="ArithmeticException">jsp/error</prop><!-- /WEB-INF/jsp/error.jsp -->
<prop key="NullPointerException">jsp/error</prop>
</props>
</property>
</bean>
JSP请求转发的视图解析器即要求jsp文件需要放置在WEB-INF文件夹中保证安全，同时自动加上前后缀，简化代码
###完成web.xml配置
配置HttpServletRequest监听器、配置Log4j的监听器、配置Spring解决缓存异常问题的监听器
<!-- 5.配置HttpServletRequest监听器,方便以后在任何层次都能获取ServletAPI -->
<listener>
<listener-class>org.springframework.web.context.request.RequestContextListener</listener-class>
</listener>
<!-- 6.配置Log4j的监听器 -->
<context-param>
<param-name>log4jConfigLocation</param-name>
<param-value>classpath:log4j.properties</param-value>
</context-param>
<context-param>
<param-name>log4jRefreshInterval</param-name>
<!-- 6秒 -->
<param-value>6000</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
</listener>
<!-- 7.Spring解决缓存异常问题的监听器 -->
<listener>
<listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class>
</listener>
<welcome-file-list>
<welcome-file>jsp/login</welcome-file>
</welcome-file-list>
##创建测试项目—模拟登陆
项目结构图
关于项目代码就不粘贴了，需要的可以去github上下载
额外配置Session拦截器SessionInterceptor.java
配置springMVC.xml
<!-- 7.Session拦截器 -->
<mvc:interceptors>
<mvc:interceptor>
<mvc:mapping path="/sys/**" />
<mvc:exclude-mapping path="/sys/login" />
<bean class="com.gobha.interceptor.SessionInterceptor" />
</mvc:interceptor>
</mvc:interceptors>
拦截器代码
import java.io.PrintWriter;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;
import org.springframework.web.servlet.handler.HandlerInterceptorAdapter;
public class SessionInterceptor extends HandlerInterceptorAdapter {
private final static String SESSION_KEY = "session_user";
@Override
public boolean preHandle( HttpServletRequest request , HttpServletResponse response , Object handler )
throws Exception {
HttpSession session = request.getSession();
if(session.getAttribute(SESSION_KEY)==null){
response.setContentType("text/html;charset=UTF-8");
PrintWriter out = response.getWriter();
out.write("<script type='text/javascript'>alert('你没有登陆！');"
+ "window.top.location.href='"+request.getContextPath()+"/sys/login';"
+ "</script>");
out.flush();
out.close();
return false;
}else{
return true;
}
}
}
