添加log4j配置文件#
-
由于MyBatis依赖与log4j输出sql语句信息，所以需要配置log4j配置文件。
#设置输出级别和输出位置 log4j.rootLogger=debug,Console #设置控制台相关的参数 log4j.appender.Console=org.apache.log4j.ConsoleAppender log4j.appender.Console.layout=org.apache.log4j.PatternLayout log4j.appender.Console.layout.ConversionPattern=%d [%t] %-5p [%c] - %m%n #设置MyBatis的输出内容 log4j.logger.java.sql.ResultSet=INFO log4j.logger.org.apache=INFO log4j.logger.java.sql.Connection=DEBUG log4j.logger.java.sql.Statement=DEBUG log4j.logger.java.sql.PreparedStatement=DEBUG
配置web.xml#
-
添加SpringMVC核心控制器DispatcheerServlet配置信息
<!-- 配置SpringMVC的处理请求的Servlet --> <servlet> <servlet-name>dispatcherServlet</servlet-name> <servlet-class> org.springframework.web.servlet.DispatcherServlet </servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:springmvc.xml</param-value> </init-param> <!-- 表示系统启动时自动加载这个servlet --> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>dispatcherServlet</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping>
添加编码过滤器#
-
添加乱码过滤器，避免提交时出现乱码。
<!-- 开启编码过滤器 --> <filter> <description>字符集过滤器</description> <filter-name>encodingFilter</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <init-param> <description>字符集编码</description> <param-name>encoding</param-name> <param-value>UTF-8</param-value> </init-param> </filter> <filter-mapping> <filter-name>encodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping>
添加put和delete请求#
-
支持put和delete请求
<!-- 设置是否支持put和delete请求 --> <filter> <filter-name>HiddenHttpMethodFilter</filter-name> <filter-class>org.springframework.web.filter.HiddenHttpMethodFilter</filter-class> </filter> <filter-mapping> <filter-name>HiddenHttpMethodFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping>
配置springmvc.xml#
-
添加springmvc的配置文件，设置自动扫描包路径，静态资源处理，视图解析器等。
<?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:context="http://www.springframework.org/schema/context" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.2.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.2.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.2.xsd"> <!-- 自动扫描基包，将类加载到Spring容器中 --> <context:component-scan base-package="com.znsd.ssm" /> <!-- 视图解析器：将逻辑视图转发到对应的物理视图 --> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/WEB-INF/views/" /> <property name="suffix" value=".jsp" /> </bean> <!-- 将静态资源交由tomcat来处理 --> <mvc:default-servlet-handler /> <!-- 注册类型转换器 --> <mvc:annotation-driven />
配置文件上传#
-
配置文件上传组件。
<!-- 配置文件上传组件 --> <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"> <!-- 指定默认的编码格式 --> <property name="defaultEncoding" value="UTF-8" /> <!-- 指定允许上传的文件大小，单位Byte --> <property name="maxUploadSize" value="512000" /> </bean>
配置druid连接池信息#
-
配置c3p0连接池信息
<!-- 加载properties配置文件 --> <context:property-placeholder location="classpath:jdbc.properties" /> <!-- druid数据源 --> <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource" init-method="init" destroy-method="close"> <!-- 基本属性 url、user、password --> <property name="driverClassName" value="${jdbc.driver}" /> <property name="url" value="jdbc:mysql://${jdbc.host}:${jdbc.port}/${jdbc.dbname}?characterEncoding=UTF-8&zeroDateTimeBehavior=convertToNull&noAccessToProcedureBodies=true" /> <property name="username" value="${jdbc.user}" /> <property name="password" value="${jdbc.password}" /> <!-- 配置初始化大小、最小、最大 --> <property name="initialSize" value="1" /> <property name="minIdle" value="1" /> <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="${jdbc.pool.timeBetweenEvictionRunsMillis}" /> <!-- 配置一个连接在池中最小生存的时间，单位是毫秒 --> <property name="minEvictableIdleTimeMillis" value="${jdbc.pool.minEvictableIdleTimeMillis}" /> <property name="validationQuery" value="SELECT 'x'" /> <property name="testWhileIdle" value="true" /> <property name="testOnBorrow" value="false" /> <property name="testOnReturn" value="false" /> <!--如果是Oracle的话需要配置一下参数 --> <!-- 打开PSCache，并且指定每个连接上PSCache的大小 --> <!--<property name="poolPreparedStatements" value="true" /> --> <!--<property name="maxPoolPreparedStatementPerConnectionSize" value="20" /> --> <!-- 配置监控统计拦截的filters --> <property name="filters" value="stat" /> </bean> -
jdbc.properties文件
##jdbc\u914D\u7F6E## jdbc.driver=com.mysql.jdbc.Driver jdbc.dbname=test jdbc.port=3306 jdbc.host=192.168.41.10 jdbc.user=znsd_test jdbc.password=123456 jdbc.pool.minPoolSize=5 jdbc.pool.maxPoolSize=30 jdbc.pool.initialPoolSize=5 jdbc.pool.maxIdleTime=60 jdbc.pool.timeBetweenEvictionRunsMillis=60000 jdbc.pool.minEvictableIdleTimeMillis=300000
配置sqlSessionFactory#
-
MyBatis中使用sqlSessionFactory来生产session对象，和Hibernate中相似，也可以交由spring来管理。
-
设置扫描的映射文件和dao包
<!-- mybatis session 工厂 --> <bean id="sessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="dataSource" ref="dataSource" /> <property name="mapperLocations"> <list> <value>classpath*:/mybatis-mapping/*.xml</value> </list> </property> <!-- 指定mybatis的配置文件(可有可无) --> <property name="configLocation" value="classpath:mybatis.xml"></property> </bean> <!-- mybatis接口 --> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <!-- mybatis 接口包（如果有多个可以用,逗号隔开） --> <property name="basePackage" value="com.znsd.ssm" /> <property name="sqlSessionFactoryBeanName" value="sessionFactory" /> <property name="annotationClass" value="org.springframework.stereotype.Repository" /> </bean>
Mybatis映射文件#
-
在SSM中，可以省略mybatis配置文件，也可以添加，只不过需要在sqlSessionFactory中配置configLocation属性即可。
<?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> <!-- 取别名，这个必须按照一定的顺序配置 --> <typeAliases> <!-- 将这个包下面的所有的类全部倒入进来，明明规则就是类名首字母小写 --> <package name="com.lxit.ssm.entities"/> <!-- 指定单独一个类的别名 --> <!-- <typeAlias type="com.lxit.ssm.entities.Student" alias="stu"/> --> </typeAliases> </configuration>
配置事务#
-
在Spring里面，可以通过AOP来管理事务，非常强大。
<!-- 定义事务管理器（声明式的事务） --> <bean id="txManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource" /> </bean> <!-- 事务的通知方式 --> <tx:advice id="txAdvice" transaction-manager="txManager"> <tx:attributes> <tx:method name="find*" propagation="REQUIRED" read-only="true" /> <tx:method name="search*" propagation="REQUIRED" read-only="true" /> <tx:method name="query*" propagation="REQUIRED" read-only="true" /> <tx:method name="add*" propagation="REQUIRED" /> <tx:method name="submit*" propagation="REQUIRED" /> <tx:method name="save*" propagation="REQUIRED" /> <tx:method name="insert*" propagation="REQUIRED" /> <tx:method name="del*" propagation="REQUIRED" /> <tx:method name="remove*" propagation="REQUIRED" /> <tx:method name="update*" propagation="REQUIRED" /> <tx:method name="modify*" propagation="REQUIRED" /> <tx:method name="*" propagation="REQUIRED" read-only="true" /> </tx:attributes> </tx:advice>
到了这里配置就已经完成了。
