一、新建Maven项目

点击菜单栏File项，选择New-》Project，选中Maven Project,如下图：

二、配置pom.xml

  1. <?xml version="1.0" encoding="UTF-8"?>
  2. <project xmlns="http://maven.apache.org/POM/4.0.0"
  3.          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  4.          xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

  175.         </dependency>
  176.  
  177.     </dependencies>
  178. </project>

三、配置springMVC

在resources文件夹下建立spring-mvc.xml,如下图

具体内部配置如下：

  1. <?xml version="1.0" encoding="UTF-8" ?>
  2. <beans xmlns="http://www.springframework.org/schema/beans"
  3.        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  4.        xmlns:context="http://www.springframework.org/schema/context"
  5.        xmlns:mvc="http://www.springframework.org/schema/mvc"
  6.        xsi:schemaLocation="http://www.springframework.org/schema/beans
  7.                         http://www.springframework.org/schema/beans/spring-beans-3.1.xsd
  8.                         http://www.springframework.org/schema/context
  9.                         http://www.springframework.org/schema/context/spring-context-3.1.xsd
  10.                         http://www.springframework.org/schema/mvc
  11.                         http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">
  12.     <!-- 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 -->
  13.     <context:component-scan base-package = "fv">
  14.         <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
  15.         <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Service"/>
  16.     </context:component-scan>
  17.  
  18.     <!--避免IE执行AJAX时，返回JSON出现下载文件 -->
  19.     <bean id = "mappingJacksonHttpMessageConverter"
  20.           class = "org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
  21.         <property name = "supportedMediaTypes">
  22.             <list>
  23.                 <value>text/html;charset=UTF-8</value>
  24.             </list>
  25.         </property>
  26.     </bean>
  27.  
  28.     <!-- 启动SpringMVC的注解功能，完成请求和注解POJO的映射 -->
  29.     <bean class="org.springframework.web.servlet.view.ContentNegotiatingViewResolver">
  30.         <property name="order" value="1"/>
  31.         <property name="defaultViews">
  32.             <list>
  33.                 <!-- JSON View -->
  34.                 <bean class="org.springframework.web.servlet.view.json.MappingJackson2JsonView">
  35.                 </bean>
  36.             </list>
  37.         </property>
  38.     </bean>
  39.  
  40.     <!-- 定义跳转的文件的前后缀 ，视图模式配置-->
  41.     <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
  42.         <!-- 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 -->
  43.         <property name="prefix" value="/WEB-INF/page/" />
  44.         <property name="suffix" value=".jsp" />
  45.         <!-- <property name="viewClass" value="org.springframework.web.servlet.view.InternalResourceView"/>   -->
  46.     </bean>
  47.  
  48.     <!-- 文件上传 -->
  49.     <!-- <bean id="multipartResolver"  class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
  50.         <property name="maxUploadSize" value="102400000"></property>
  51.     </bean> -->
  52.    <!-- <mvc:interceptors>
  53.         <mvc:interceptor>
  54.             <mvc:mapping path="/mvc/**"/>
  55.             <bean class="test.SpringMVC.Interceptor.MyInterceptor"></bean>
  56.         </mvc:interceptor>
  57.     </mvc:interceptors> -->
  58.     <!-- 添加后可以显示welcome-file界面 -->
  59.     <mvc:default-servlet-handler/>
  60.  
  61.     <!-- 启动注解 -->
  62.     <mvc:annotation-driven />
  63. </beans>

四、整合mybatis

在resource文件夹下建立spring-mybatis.xml文件夹，配置内容如下：

　　

  1. <?xml version="1.0" encoding="UTF-8" ?>
  2. <beans xmlns="http://www.springframework.org/schema/beans"
  3.        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  4.        xmlns:context="http://www.springframework.org/schema/context"
  5.        xmlns:tx="http://www.springframework.org/schema/tx"
  6.        xsi:schemaLocation="http://www.springframework.org/schema/beans
  7.                         http://www.springframework.org/schema/beans/spring-beans-3.1.xsd
  8.                         http://www.springframework.org/schema/context
  9.                         http://www.springframework.org/schema/context/spring-context-3.1.xsd
  10.                         http://www.springframework.org/schema/tx
  11.                         http://www.springframework.org/schema/tx/spring-tx.xsd">
  12.     <!-- 自动扫描 -->
  13.     <context:component-scan base-package="fv">
  14.         <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
  15.     </context:component-scan>
  16.  
  17.     <!-- 引入数据库配置文件 -->
  18.     <bean id = "propertyConfigurer"
  19.           class = "org.springframework.beans.factory.config.PreferencesPlaceholderConfigurer">
  20.         <property name = "location" value="classpath:jdbc.properties" />
  21.     </bean>
  22.     <!-- 连接池 -->
  23.     <bean id = "dataSource" class = "org.apache.commons.dbcp.BasicDataSource"
  24.           destroy-method = "close">
  25.         <property name="driverClassName" value="${jdbc.driver}" />
  26.         <property name="url" value="${jdbc.url}" />
  27.         <property name="username" value="${jdbc.username}" />
  28.         <property name="password" value="${jdbc.password}" />
  29.         <!-- 初始化连接大小 -->
  30.         <property name="initialSize" value="${jdbc.initialSize}" />
  31.         <!-- 连接池最大数量 -->
  32.         <property name="maxActive" value="${jdbc.maxActive}"/>
  33.         <!-- 连接池最大空闲 -->
  34.         <property name="maxIdle" value="${jdbc.maxIdle}" />
  35.         <!-- 连接池最小空闲 -->
  36.         <property name="minIdle" value="${jdbc.minIdle}" />
  37.         <!-- 获取连接最大等待时间 -->
  38.         <property name="maxWait" value="${jdbc.maxWait}" />
  39.     </bean>
  40.  
  41.     <!-- 结合Spring和Mybatis -->
  42.     <bean id = "sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
  43.         <property name="dataSource" ref="dataSource" />
  44.         <!-- 自动扫描mapping.xml文件 -->
  45.         <property name = "mapperLocations" value="classpath:fv/mapping/*.xml" />
  46.     </bean>
  47.  
  48.     <!-- DAO接口所在包名，Spring会自动查找其下的类 -->
  49.     <bean class = "org.mybatis.spring.mapper.MapperScannerConfigurer">
  50.         <property name = "basePackage" value="fv.dao" />
  51.         <property name = "sqlSessionFactoryBeanName" value = "sqlSessionFactory" />
  52.     </bean>
  53.  
  54.     <!-- 定义事务 -->
  55.     <bean id = "transactionManager"
  56.           class = "org.springframework.jdbc.datasource.DataSourceTransactionManager">
  57.         <property name = "dataSource" ref = "dataSource" />
  58.     </bean>
  59.     <!-- 使用注解定义事务 -->
  60.     <tx:annotation-driven transaction-manager = "transactionManager" />
  61. </beans>

　五、配置属性文件

在此总共有两个属性文件，一个是log4j.properties,另一哥是数据库连接文件jdbc.properties;

log4j.properties文件内容如下：

  1. #定义LOG输出级别
  2. log4j.rootLogger=INFO,Console,File
  3. #定义日志输出目的地为控制台
  4. log4j.appender.Console=org.apache.log4j.ConsoleAppender
  5. log4j.appender.Console.Target=System.out
  6. #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
  7. log4j.appender.Console.layout = org.apache.log4j.PatternLayout
  8. log4j.appender.Console.layout.ConversionPattern=[%c] - %m%n
  9.  
  10. #文件大小到达指定尺寸的时候产生一个新的文件
  11. log4j.appender.File = org.apache.log4j.RollingFileAppender
  12. #指定输出目录
  13. log4j.appender.File.File = logs/ssm.log
  14. #定义文件最大大小
  15. log4j.appender.File.MaxFileSize = 10MB
  16. # 输出所以日志，如果换成DEBUG表示输出DEBUG以上级别日志
  17. log4j.appender.File.Threshold = ALL
  18. log4j.appender.File.layout = org.apache.log4j.PatternLayout
  19. log4j.appender.File.layout.ConversionPattern =[%p] [%d{yyyy-MM-dd HH\:mm\:ss}][%c]%m%n

jdbc.properties文件如下:

  1. jdbc.driver=oracle.jdbc.driver.OracleDriver
  2. jdbc.url=jdbc:oracle:thin:@192.168.1.213:1521:orcl
  3. jdbc.username=KYYS
  4. jdbc.password=kyys
  5. #定义初始连接数
  6. jdbc.initialSize=0
  7. #定义最大连接数
  8. jdbc.maxActive=20
  9. #定义最大空闲
  10. jdbc.maxIdle=20
  11. #定义最小空闲
  12. jdbc.minIdle=1
  13. #定义最长等待时间
  14. jdbc.maxWait=60000

　在webapp/WEB-INF/下web.xml文件内容如下：

  1. <?xml version="1.0" encoding="UTF-8"?>
  2. <web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
  3.          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  4.          xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
  5.          version="3.1">
  6.     <display-name>Archetype Created Web Application</display-name>
  7.     <!-- Spring和Mybatis的配置文件 -->
  8.     <context-param>
