Before building the project framework ...
项目环境
IntelliJ IDEA 2016.1.2、JDK 1.8.0_31、Apache-maven-3.5.0、Tomcat-9.0.0.M11
Maven项目搭建
自行百度 ..
Build project framework ...
1.项目pom.xml文件

2.spring-mvc.xml
(第一句扫描注解，扫描出的注解对象都依赖注入到了Spring MVC容器中，这时不可再次扫描Service，不然事务不能用了，所以扫描时将Service除去，这时必须扫描Controller，不然服务会出404错误。)
<?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" 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"> <!-- 自动扫描该包，使用SpringMVC认为包下用了@Controller注解的类是控制器,避免扫描@Service导致事务不能使用 --> <context:component-scan base-package = "com.xiaonan.project"> <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/> <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Service"/> </context:component-scan> <!--避免IE执行AJAX时，返回JSON出现下载文件 --> <bean id = "mappingJacksonHttpMessageConverter" class = "org.springframework.http.converter.json.MappingJackson2HttpMessageConverter"> <property name = "supportedMediaTypes"> <list> <value>text/html;charset=UTF-8</value> </list> </property> </bean> <!-- 启动SpringMVC的注解功能，完成请求和注解POJO的映射 --> <bean class="org.springframework.web.servlet.view.ContentNegotiatingViewResolver"> <property name="order" value="1"/> <property name="defaultViews"> <list> <!-- JSON View --> <bean class="org.springframework.web.servlet.view.json.MappingJackson2JsonView"> </bean> </list> </property> </bean> <!-- 定义跳转的文件的前后缀 ，视图模式配置--> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <!-- 自动给后面action的方法return的字符串加上前缀和后缀，变成一个 可用的url地址 --> <property name="prefix" value="/page/" /> <property name="suffix" value=".jsp" /> </bean> <!-- 添加后可以显示welcome-file界面 --> <mvc:default-servlet-handler/> <!-- 启动注解 --> <mvc:annotation-driven /> </beans>
3.spring-mybatis.xml
(第一句自动扫描是为了扫描包中的注解，然后进行依赖注入，这时所有扫描的注解对象都在Spring容器中。配置数据源，整合使用Mybatis)
<?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"> <!-- 自动扫描 --> <context:component-scan base-package="com.xiaonan.project"> <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/> </context:component-scan> <!-- 引入数据库配置文件 --> <bean id = "propertyConfigurer" class = "org.springframework.beans.factory.config.PreferencesPlaceholderConfigurer"> <property name = "location" value="classpath:properties/jdbc.properties" /> </bean> <!-- 连接池 --> <bean id = "dataSource" class = "org.apache.commons.dbcp.BasicDataSource" destroy-method = "close"> <property name="driverClassName" value="${jdbc.driver}" /> <property name="url" value="${jdbc.url}" /> <property name="username" value="${jdbc.username}" /> <property name="password" value="${jdbc.password}" /> <!-- 初始化连接大小 --> <property name="initialSize" value="${jdbc.initialSize}" /> <!-- 连接池最大数量 --> <property name="maxActive" value="${jdbc.maxActive}"/> <!-- 连接池最大空闲 --> <property name="maxIdle" value="${jdbc.maxIdle}" /> <!-- 连接池最小空闲 --> <property name="minIdle" value="${jdbc.minIdle}" /> <!-- 获取连接最大等待时间 --> <property name="maxWait" value="${jdbc.maxWait}" /> </bean> <!-- 结合Spring和Mybatis --> <bean id = "sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="dataSource" ref="dataSource" /> <!-- 自动扫描mapping.xml文件 --> <property name = "mapperLocations" value="classpath:mapper/*Mapper.xml" /> </bean> <!-- DAO接口所在包名，Spring会自动查找其下的类 --> <bean class = "org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name = "basePackage" value="com.xiaonan.project.mapper" /> <property name = "sqlSessionFactoryBeanName" value = "sqlSessionFactory" /> </bean> <!-- 定义事务 --> <bean id = "transactionManager" class = "org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name = "dataSource" ref = "dataSource" /> </bean> <!-- 使用注解定义事务 --> <tx:annotation-driven transaction-manager = "transactionManager" /> </beans>
4.jdbc.properties
(设置好一些基本属性，可以直接在spring-mybatis.xml中使用${属性名}访问)
## oracle 定义 jdbc.driver=oracle.jdbc.driver.OracleDriver jdbc.url=jdbc:oracle:thin:@127.0.0.1:1521:orcl jdbc.username=bms jdbc.password=bms #定义初始连接数 jdbc.initialSize=0 #定义最大连接数 jdbc.maxActive=100 #定义最大空闲 jdbc.maxIdle=20 #定义最小空闲 jdbc.minIdle=1 #定义最长等待时间 jdbc.maxWait=60000
5.log4j.properties
#定义LOG输出级别 log4j.rootLogger=INFO,Console,File #定义日志输出目的地为控制台 log4j.appender.Console=org.apache.log4j.ConsoleAppender log4j.appender.Console.Target=System.out #可以灵活地指定日志输出格式，下面一行是指定具体的格式 log4j.appender.Console.layout = org.apache.log4j.PatternLayout log4j.appender.Console.layout.ConversionPattern=[%c] - %m%n #文件大小到达指定尺寸的时候产生一个新的文件 log4j.appender.File = org.apache.log4j.RollingFileAppender #指定输出目录 log4j.appender.File.File = logs/ssm.log #定义文件最大大小 log4j.appender.File.MaxFileSize = 10MB # 输出所以日志，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] [%d{yyyy-MM-dd HH\:mm\:ss}][%c]%m%n
6.web.xml
(初始化加载spring-mybatis.xml文件。ContextLoaderListener监听器的作用就是启动Web容器时自动装配ApplicationContext的配置信息。若无该语句，就无法依赖注入注解标注产生的对象)
<?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> <!-- Spring和Mybatis的配置文件 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:application/spring-mybatis.xml</param-value> </context-param> <!-- 编码过滤器 --> <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> <!-- 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> <!-- Spring MVC servlet --> <servlet> <servlet-name>SpringMVC</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name>
