Idea+Maven+Spring+SpringMVC+MyBatis环境搭建

Idea+Maven+Spring+SpringMVC+MyBatis环境搭建

首先搭建Spring+MyBatis环境

在单独MyBatis中,使用SqlSessionFactoryBuilder创建SqlSessionFactory,然后创建SqlSession.Mybatis社区自己开发了一个Mybatis-spring用来满足Mybatis用户整合Spring的需求。为了代替手工使用 SqlSessionDaoSupport 或 SqlSessionTemplate 编写数据访问对象 (DAO)的代码,MyBatis-Spring 提供了一个动态代理的实现:MapperFactoryBean。这个类可以让你直接注入数据映射器接口到你的 service 层 bean 中。当使用映射器时,你仅仅如调用你的DAO一样调用它们就可以了,但是你不需要编写任何 DAO 实现的代码,因为 MyBatis-Spring 将会为你创建代理。 详细参考:http://www.mybatis.org/spring/zh/index.html

工程目录结构如图

可以使用MyBatis generator生成Dao和Mapper代码,防止手写出现错误.

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" 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"> <!-- 自动扫描 --> <context:component-scan base-package="controller,dao,model,service" /> <!-- 导入properties配置文件 --> <bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> <property name="location" value="classpath:jdbc.properties" /> </bean> <!-- 配置数据源使用SpEL表达式 --> <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close"> <property name="driverClassName" value="${driver}" /> <property name="url" value="${url}" /> <property name="username" value="${username}" /> <property name="password" value="${password}" /> <!-- 初始化连接大小 --> <property name="initialSize" value="${initialSize}"></property> <!-- 连接池最大数量 --> <property name="maxActive" value="${maxActive}"></property> <!-- 连接池最大空闲 --> <property name="maxIdle" value="${maxIdle}"></property> <!-- 连接池最小空闲 --> <property name="minIdle" value="${minIdle}"></property> <!-- 获取连接最大等待时间 --> <property name="maxWait" value="${maxWait}"></property> </bean> <!-- spring和MyBatis整合时，使用SqlSessionFactoryBean则放弃了mybatis的配置映射文件 --> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <!-- 注入数据源 --> <property name="dataSource" ref="dataSource" /> <!-- 自动扫描mapping.xml文件 --> <property name="mapperLocations" value="classpath:mapping/*.xml"/> </bean> <!-- 配置MapperScannerConfigurer之后,不需要我们写Dao实现类,需要告诉MapperScannerConfigurer,Dao接口在哪 --> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="dao" /> <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" /> </bean> <!-- 配置事务 --> <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource" /> </bean> </beans>

jdbc.properties

driver=com.mysql.jdbc.Driver url=jdbc:mysql://localhost:3306/sas?useUnicode=true&characterEncoding=utf-8&zeroDateTimeBehavior=convertToNull username=root password=mysql #定义初始连接数 initialSize=0 #定义最大连接数 maxActive=20 #定义最大空闲 maxIdle=20 #定义最小空闲 minIdle=1 #定义最长等待时间 maxWait=60000

log4j.properties

log4j.rootLogger=INFO,Console,File #控制台日志 log4j.appender.Console=org.apache.log4j.ConsoleAppender log4j.appender.Console.Target=System.out log4j.appender.Console.layout=org.apache.log4j.PatternLayout log4j.appender.Console.layout.ConversionPattern=[%p][%t][%d{yyyy-MM-dd HH\:mm\:ss}][%C] - %m%n #普通文件日志 log4j.appender.File=org.apache.log4j.RollingFileAppender log4j.appender.File.File=logs/ssm.log log4j.appender.File.MaxFileSize=10MB #输出日志，如果换成DEBUG表示输出DEBUG以上级别日志 log4j.appender.File.Threshold=ALL log4j.appender.File.layout=org.apache.log4j.PatternLayout log4j.appender.File.layout.ConversionPattern=[%p][%t][%d{yyyy-MM-dd HH\:mm\:ss}][%C] - %m%n

然后搭建Spring+SpringMVC环境

---

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-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/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd"> <!-- 启动Springmvc注解--> <mvc:annotation-driven/> <!-- 自动扫描该包，使SpringMVC认为包下用了@controller注解的类是控制器 --> <context:component-scan base-package="controller"> <!-- 只是扫描Controller注解 --> <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/> </context:component-scan> <!-- 排除静态资源的默认方式 --> <mvc:default-servlet-handler default-servlet-name="default"/> <!-- 配置视图解析器 --> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/WEB-INF/"/> <property name="suffix" value=".jsp"/> </bean> <!-- 配置文件上传 --> <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"> <!-- 默认编码 --> <property name="defaultEncoding" value="utf-8"/> <!-- 文件大小最大值 --> <property name="maxUploadSize" value="10485760000"/> <!-- 内存中的最大值 --> <property name="maxInMemorySize" value="40960"/> </bean> </beans>

最后配置web.xml

<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0"> <display-name>Archetype Created Web Application</display-name> <!-- 加载Spring-mybatis的配置文件 ->通过Spring的监听器加载 spring-mybatis.xml的配置文件 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring-mybatis.xml</param-value> </context-param> <!-- Spring监听器 --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- 防止Spring内存溢出监听器 --> <listener> <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class> </listener> <!-- 编码过滤器 必须配置在所有过滤器的最前面 --> <filter> <filter-name>encodingFilter</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <async-supported>true</async-supported> <init-param> <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> <!-- 配置REST风格： get请求代表查询 post 添加 delete 删除 put 等幂更新 patch 不等幂更新 --> <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的Servlet -> DispatcherServlet --> <servlet> <servlet-name>SpringMVC</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring-mvc.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> <async-supported>false</async-supported> </servlet> <servlet-mapping> <servlet-name>SpringMVC</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> <welcome-file-list> <welcome-file>/login.jsp</welcome-file> </welcome-file-list> </web-app> posted on 2016-12-26 14:56  MonkeyB 阅读( ...) 评论( ...) 编辑 收藏
