Remember_Ray 人气:0第一步:添加数据库配置文件
jdbc.properties
# 数据库驱动 jdbc.driver=com.mysql.jdbc.Driver # 数据库地址 jdbc.url=jdbc:mysql://localhost:3306/library?useUnicode=true&characterEncoding=UTF-8 # 用户名 jdbc.username=root # 密码 jdbc.password=root # 初始化连接 initialSize=0 # 最大连接数量 maxActive=20 # 最大空闲连接 maxIdle=20 # 最小空闲连接 minIdle=1 # 超时等待时间 maxWait=60000
第二步:添加mybatis配置文件
mybatis-config.xml
<?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> <!-- 配置全局属性 --> <settings> <!-- 使用jdbc的getGeneratedKeys获取主键 --> <setting name="useGeneratedKeys" value="true"/> <!-- 使用别名替换列名, 默认ture --> <setting name="useColumnLabel" value="true"/> <!-- 开启驼峰命名转换 --> <setting name="mapUnderscoreToCamelCase" value="true"/> </settings> </configuration>
第三步:添加Spring配置文件
在resources/spring目录下新建二个文件:
│ └── spring
│ ├── spring-mybatis.xml
│ ├── spring-service.xml
│ └── spring-mvc.xml
spring-mvc.xml
<?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:mvc="http://www.springframework.org/schema/mvc" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd"> <!-- 注册组件扫描器 --> <context:component-scan base-package="com.ray.controller"/> <!-- 访问静态资源 --> <mvc:default-servlet-handler/> <!-- 开启注解模式 --> <mvc:annotation-driven> <mvc:message-converters> <bean class="org.springframework.http.converter.StringHttpMessageConverter"> <property name="supportedMediaTypes"> <list> <!-- 解决中文乱码 --> <value>text/plain;charset=UTF-8</value> <value>text/html;charset=UTF-8</value> <value>application/json;charset=UTF-8</value> </list> </property> </bean> </mvc:message-converters> </mvc:annotation-driven> <!-- 视图解析器 --> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <!-- 前缀 --> <property name="prefix" value="/WEB-INF/views/"/> <!-- 后缀 --> <property name="suffix" value=".jsp"/> </bean> </beans>
spring-mybatis.xml
<?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:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd"> <!-- 1.配置数据库相关参数 --> <context:property-placeholder location="classpath:jdbc.properties"/> <!-- 2.配置druid数据源 --> <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource" init-method="init" destroy-method="close"> <!-- 配置连接池属性 --> <property name="driverClassName" value="${jdbc.driver}"/> <property name="url" value="${jdbc.url}"/> <property name="username" value="${jdbc.username}"/> <property name="password" value="${jdbc.password}"/> <!-- 配置初始化大小,最小,最大值 --> <property name="initialSize" value="1"/> <property name="minIdle" value="1"/> <property name="maxActive" value="10"/> <!-- 配置获取连接等待超时的时间 --> <property name="maxWait" value="10000"/> <!-- 配置间隔多久才进行一次检测,检测需要关闭空闲连接,单位毫秒 --> <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"/> <!-- 验证连接有效与否的SQL,不同的数据配置不同 --> <property name="validationQuery" value="SELECT 1" /> <!-- 如果空闲时间大于timeBetweenEvictionRunsMillis,执行validationQuery检测连接是否有效 --> <property name="testWhileIdle" value="true"/> <!-- 这里建议配置为TRUE,防止取到的连接不可用 --> <property name="testOnBorrow" value="true"/> <property name="testOnReturn" value="false"/> <!-- 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"/> <!-- 这里配置提交方式,默认就是TRUE,可以不用配置 --> <property name="defaultAutoCommit" value="true" /> <!-- 开启Druid的监控统计功能 --> <property name="filters" value="stat"/> </bean> <!-- 3.配置Mybatis的SqlSessionFactory对象 --> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <!-- 配置MyBatis全局配置文件 --> <property name="configLocation" value="classpath:mybatis-config.xml"/> <!-- 注入数据库连接池 --> <property name="dataSource" ref="dataSource"/> <!-- 扫描配置文件 --> <property name="mapperLocations" value="classpath:mapping/*.xml"/> </bean> <!-- 4.配置扫描Dao接口包,动态实现Dao接口,注入到spring容器中 --> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <!-- 给出需要扫描Dao接口包 --> <property name="basePackage" value="com.ray.dao"/> </bean> </beans>
spring-service.xml
<?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: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.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd"> <!-- 自动扫描 --> <context:component-scan base-package="com.ray"/> <!-- 事务管理 --> <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource"/> </bean> <!-- 开启事务控制的注解支持 --> <tx:annotation-driven transaction-manager="transactionManager"/> </beans>
第四步:添加logback配置文件
logback配置比log4j要简单点,功能类似
├── resources
│ ├── logback.xml
在resources文件夹下新建文件:logback.xml
<?xml version="1.0" encoding="UTF-8" ?> <configuration debug="true"> <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender"> <encoder> <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern> </encoder> </appender> <!--开启debug日志模式,在控制台打印日志--> <root level="debug"> <appender-ref ref="STDOUT" /> </root> </configuration>
第五步:配置web.xml
web.xml
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" version="3.1" metadata-complete="true"> <display-name>Archetype Created Web Application</display-name> <!-- 配置DispatcherServlet --> <servlet> <servlet-name>seckill-dispatcher</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <!-- 配置springMVC需要加载的配置文件 spring-dao.xml,spring-service.xml,spring-web.xml Mybatis - > spring -> springmvc --> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring/spring-*.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> <async-supported>true</async-supported> </servlet> <servlet-mapping> <servlet-name>seckill-dispatcher</servlet-name> <!-- 默认匹配所有的请求 --> <url-pattern>/</url-pattern> </servlet-mapping> <!-- 处理中文乱码 --> <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> </filter> <filter-mapping> <filter-name>CharacterEncodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> </web-app>
