实习小结（五）--- SSM框架搭建（Maven项目）
之前分享了一个普通的SSM框架的搭建方法，感觉还是过于老套，现在都流行使用Maven来管理项目，在这分享一个使用Maven搭建的SSM（SpringMVC+Spring+MyBatis）
1、首先maven项目的最重要的部分是在pom.xml中添加依赖
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0

</dependencies> <build> <finalName>traineeManage</finalName> </build> </project>
2、在resources下存放一些配置文件信息，包括MyBatis中的实体类映射文件
（1）applicationContext.xml是Spring的配置文件，其中包括了连接数据库，配置mybatis的sqlSessionFactory，dao接口，事务，以及Shiro，aop的配置
<?xml version="1.0" encoding="UTF-8"?> <!--suppress ALL --> <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:aop="http://www.springframework.org/schema/aop" xmlns:context="http://www.springframework.org/schema/context" xmlns:jee="http://www.springframework.org/schema/jee" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation=" http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd 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/jee http://www.springframework.org/schema/jee/spring-jee-4.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd"> <context:property-placeholder location="classpath:jdbc.properties"/> <!-- 配置数据源 --> <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource"> <property name="url" value="${jdbc.url}"/> <property name="username" value="${jdbc.username}"/> <property name="password" value="${jdbc.password}"/> </bean> <!-- 配置mybatis的sqlSessionFactory --> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="dataSource" ref="dataSource" /> <!-- 自动扫描mappers.xml文件 --> <property name="mapperLocations" value="classpath:com/tm/mappers/*.xml"/> <!-- mybatis配置文件 --> <property name="configLocation" value="classpath:mybatis-config.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.tm.dao" /> <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/> </bean> <!-- (事务管理)transaction manager, use JtaTransactionManager for global tx --> <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource" /> </bean> <!-- 自定义Realm --> <bean id="myRealm" class="com.tm.realm.MyRealm"/> <!-- 安全管理器 --> <bean id="securityManager" class="org.apache.shiro.web.mgt.DefaultWebSecurityManager"> <property name="realm" ref="myRealm"/> </bean> <!-- Shiro过滤器 --> <bean id="shiroFilter" class="org.apache.shiro.spring.web.ShiroFilterFactoryBean"> <!-- Shiro的核心安全接口,这个属性是必须的 --> <property name="securityManager" ref="securityManager"/> <!-- 身份认证失败，则跳转到登录页面的配置 --> <property name="loginUrl" value="/login.jsp"/> <!-- Shiro连接约束配置,即过滤链的定义 --> <property name="filterChainDefinitions"> <value> <!-- 配置不需要拦截的请求 --> /emp/login.do=anon /login.do = anon /assets/**=anon <!-- 配置退出过滤器,其中的具体的退出代码由Shiro实现了 --> /logout=logout <!-- 拦截其他所有请求 --> /**=authc </value> </property> </bean> <!-- 保证实现了Shiro内部lifecycle（生命周期）函数的bean执行 --> <bean id="lifecycleBeanPostProcessor" class="org.apache.shiro.spring.LifecycleBeanPostProcessor"/> <!-- 开启Shiro注解 --> <bean class="org.springframework.aop.framework.autoproxy.DefaultAdvisorAutoProxyCreator" depends-on="lifecycleBeanPostProcessor"/> <bean class="org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor"> <property name="securityManager" ref="securityManager"/> </bean> <!-- 配置事务通知属性 --> <tx:advice id="txAdvice" transaction-manager="transactionManager"> <!-- 定义事务传播属性 --> <tx:attributes> <tx:method name="insert*" propagation="REQUIRED" /> <tx:method name="update*" propagation="REQUIRED" /> <tx:method name="edit*" propagation="REQUIRED" /> <tx:method name="save*" propagation="REQUIRED" /> <tx:method name="add*" propagation="REQUIRED" /> <tx:method name="new*" propagation="REQUIRED" /> <tx:method name="set*" propagation="REQUIRED" /> <tx:method name="remove*" propagation="REQUIRED" /> <tx:method name="delete*" propagation="REQUIRED" /> <tx:method name="change*" propagation="REQUIRED" /> <tx:method name="check*" propagation="REQUIRED" /> <tx:method name="get*" propagation="REQUIRED" read-only="true" /> <tx:method name="find*" propagation="REQUIRED" read-only="true" /> <tx:method name="load*" propagation="REQUIRED" read-only="true" /> <tx:method name="*" propagation="REQUIRED" read-only="true" /> </tx:attributes> </tx:advice> <!-- 配置事务切面 --> <aop:config> <aop:pointcut id="serviceOperation" expression="execution(* com.tm.service.*.*(..))" /> <aop:advisor advice-ref="txAdvice" pointcut-ref="serviceOperation" /> </aop:config> <!-- 自动扫描 --> <context:component-scan base-package="com.tm.service" /> </beans>
（2）jdbc.properties和log4j.properties是连接数据库的信息和打印日志的信息
jdbc.properties
#jdbc.name= jdbc.url=jdbc:mysql://localhost:3306/studentmanager?characterEncoding=utf8&useSSL=no jdbc.username=root jdbc.password=root
log4j.properties
log4j.rootLogger=DEBUG, Console
#Console
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
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
（3）mybatis-config.xml是MyBatis的配置文件
<?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> <!-- 别名 --> <typeAliases> <package name="com.tm.entity"/> </typeAliases> </configuration>
（4）spring-mvc.xml是SpringMVC的配置文件
<?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:aop="http://www.springframework.org/schema/aop" xmlns:context="http://www.springframework.org/schema/context" xmlns:jee="http://www.springframework.org/schema/jee" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:mvc="http://www.springframework.org/schema/mvc" xsi:schemaLocation=" http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-4.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd"> <mvc:annotation-driven> <!-- 解决@ResponseBody中文乱码 --> <mvc:message-converters> <bean class="org.springframework.http.converter.StringHttpMessageConverter"> <constructor-arg value="UTF-8" /> </bean> </mvc:message-converters> </mvc:annotation-driven> <!-- 视图解析器 --> <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/" /> <property name="suffix" value=".jsp"></property> </bean> <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"> <property name="defaultEncoding" value="UTF-8"/> <property name="maxUploadSize" value="10000000"/> </bean> <!-- 使用注解的包，包括子集 --> <context:component-scan base-package="com.tm.controller" /> </beans>
（5）最后是web.xml文件
<?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" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0"> <display-name>Archetype Created Web Application</display-name> <!-- 该监听器监听应用的启动，加载Spring的配置文件，默认加载WEB-INF下的名字为applicationContext.xml文件 并创建Spring容器 --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <filter> <filter-name>shiroFilter</filter-name> <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class> <init-param> <!-- 该值缺省为false,表示生命周期由SpringApplicationContext管理,设置为true则表示由servlet container管理 --> <param-name>targetFilterLifecycle</param-name> <param-value>true</param-value> </init-param> </filter> <filter-mapping> <filter-name>shiroFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- 告诉ContextLoaderListener下面配置的文件也是需要加载的 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicationContext.xml</param-value> </context-param> <!-- 拦截器用于解决post请求中请求参数值可能出现乱码的情况 --> <filter> <filter-name>characterEncoding</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>characterEncoding</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- 配置SpringMVC中的分发控制器DispatcherServlet 默认加载WEB-INF下的springmvc-servlet.xml --> <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> </servlet> <servlet-mapping> <servlet-name>springmvc</servlet-name> <url-pattern>*.do</url-pattern> </servlet-mapping> <welcome-file-list> <welcome-file>/login.jsp</welcome-file> </welcome-file-list> </web-app>
SSM框架的配置文件就放在这里，以后若有用到搭建环境的时候，直接可以拿去使用。
