maven整合ssm框架
一、建立maven web工程
建立完成後，項目結構以下前端
二、項目配置文件
在pom.xml中添加SSM框架相關jar包的依賴關係，pom.xml代碼以下
<?xml version="1.0" encoding="UTF-8"?> <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

在main下建立resources文件夾和java文件夾
在java文件夾下建立包結構
在resources文件夾下建立mybatis、spring和springmvc文件夾，以及jdbc.properties、log4j.properties文件
jdbc.properties
jdbc.driver=com.mysql.jdbc.Driver jdbc.url=jdbc:mysql://localhost:3306/test?characterEncoding=utf-8 jdbc.username=root jdbc.password=root
log4j.properties
log4j.rootLogger=DEBUG,A1 log4j.appender.A1=org.apache.log4j.ConsoleAppender log4j.appender.A1.layout=org.apache.log4j.PatternLayout log4j.appender.A1.layout.ConversionPattern=%-d{yyyy-MM-dd HH:mm:ss,SSS} [%t] [%c]-[%p] %m%n
在mybatis文件夾下建立SqlMapConfig.xml文件，並給出內容
<?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>
<!--分頁插件-->
<plugins>
<plugin interceptor="com.github.pagehelper.PageHelper">
<property name="dialect" value="mysql"/>
</plugin>
</plugins>
</configuration>
在spring文件夾下建立applicationContext-dao.xml、applicationContext-service.xml、applicationContext-trans.xml三個文件，分別給出內容
applicationContext-dao.xml
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.2.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.2.xsd"> <!-- 數據庫鏈接池 --> <!-- 加載配置文件 --> <context:property-placeholder location="classpath:jdbc.properties"/> <!-- 數據庫鏈接池 --> <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource" destroy-method="close"> <property name="url" value="${jdbc.url}"/> <property name="username" value="${jdbc.username}"/> <property name="password" value="${jdbc.password}"/> <property name="driverClassName" value="${jdbc.driver}"/> <property name="maxActive" value="10"/> <property name="minIdle" value="5"/> </bean> <!-- 讓Spring管理sqlSessionFactory 使用Mybatis和Spring整合包中的 --> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <!-- 數據庫鏈接池 --> <property name="dataSource" ref="dataSource"/> <!-- 加載Mybatis全局配置文件 --> <property name="configLocation" value="classpath:mybatis/SqlMapConfig.xml"/> </bean> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="cn.zhuangxp.dao"/> </bean> </beans>
applicationContext-service.xml
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.2.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.2.xsd"> <!--配置包掃描器--> <context:component-scan base-package="cn.zhuangxp.service"/> </beans>
applicationContext-trans.xml
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.2.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.2.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.2.xsd"> <!-- 事務管理器 --> <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <!-- 數據源 --> <property name="dataSource" ref="dataSource" /> </bean> <!-- 通知 --> <tx:advice id="txAdvice" transaction-manager="transactionManager"> <tx:attributes> <!-- 傳播行爲 --> <tx:method name="save*" propagation="REQUIRED" /> <tx:method name="insert*" propagation="REQUIRED" /> <tx:method name="add*" propagation="REQUIRED" /> <tx:method name="create*" propagation="REQUIRED" /> <tx:method name="delete*" propagation="REQUIRED" /> <tx:method name="update*" propagation="REQUIRED" /> <tx:method name="find*" propagation="SUPPORTS" read-only="true" /> <tx:method name="select*" propagation="SUPPORTS" read-only="true" /> <tx:method name="get*" propagation="SUPPORTS" read-only="true" /> </tx:attributes> </tx:advice> <!-- 切面 --> <aop:config> <aop:advisor advice-ref="txAdvice" pointcut="execution(* cn.zhuangxp.service.*.*(..))" /> </aop:config> </beans>
在springmvc下面建立springmvc.xml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: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-4.2.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.2.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.2.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task.xsd"> <!--掃描@Controller註解--> <mvc:annotation-driven/> <context:component-scan base-package="cn.zhuangxp.controller"/> <!--SpringMVC視圖解析器--> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/WEB-INF/views/"/> <property name="suffix" value=".jsp"/> </bean> <!-- 文件上傳解析器 --> <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"> <!-- 設定默認編碼 --> <property name="defaultEncoding" value="UTF-8"></property> <!-- 設定文件上傳的最大值5MB，5*1024*1024 --> <property name="maxUploadSize" value="5242880"></property> </bean> <!--配置資源映射--> <!-- /會攔截搜索資源，包括靜態資源 --> <!--<mvc:resources mapping="/resources/**" location="/resources/"/>--> </beans>
web.xml配置
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd" > <web-app> <display-name>ssm-demo</display-name> <!-- 加載spring容器 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring/applicationContext*.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- 解決POST亂碼 --> <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> <!-- SpringMVC前端控制器 --> <servlet> <servlet-name>ssm-demo</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <!-- contextConfigLocation不是必須的，若是不配置，SpringMVC的配置文件默認在：WEB-INF/servlet的name+"-servlet.xml" --> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:springmvc/springmvc.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <!--"/"攔截全部請求--> <servlet-mapping> <servlet-name>ssm-demo</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> </web-app>
三、測試
controller
@Controller public class TestController { @Autowired public TestService testService; @GetMapping("/getNow") @ResponseBody public String test(){ String now = testService.getNow(); return now; } }
service接口
public interface TestService { public String getNow(); }
service實現類
@Service public class TestServiceImpl implements TestService { @Autowired public TestMapper testMapper; @Override public String getNow() { return testMapper.getNow(); } }
mapper接口
public interface TestMapper { public String getNow(); }
mapper.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="cn.zhuangxp.dao.TestMapper">
<select id="getNow" resultType="java.lang.String">
select now()
</select>
</mapper>
配置tomcat,啓動項目，訪問
http://localhost:8080/getNow
