阿新 • • 發佈：2019-01-26
開啟idea File->New->Project 新建一個maven web 專案
下一步 填寫GroupId和ArtifactId
下一步 專案名和存放路徑
finish，完善的專案的目錄結構如下圖所示：
然後開始配置pom.xml
<properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <maven.compiler.source>1.7</maven.compiler.source> <maven.compiler.target>1.7</maven.compiler.target> <!--版本資訊統一定義--> <springframework.version>4.2.2.RELEASE</springframework.version> <servlet-api.version>3.1.0</servlet-api.version> <jstl.version>1.1.2</jstl.version> <mybatis.version>3.4.1</mybatis.version> <jdbc.version>5.1.35</jdbc.version> </properties> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.11</version> <scope>test</scope> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</artifactId> <version>${servlet-api.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>${springframework.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-tx</artifactId> <version>${springframework.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>${springframework.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>${springframework.version}</version> </dependency> <dependency> <groupId>jstl</groupId> <artifactId>jstl</artifactId> <version>${jstl.version}</version> </dependency> <!-- 資料庫連線池 --> <dependency> <groupId>com.mchange</groupId> <artifactId>c3p0</artifactId> <version>0.9.5.2</version> </dependency> <!-- 資料庫驅動 --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>${jdbc.version}</version> </dependency> <!-- MyBatis --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>${mybatis.version}</version> </dependency> <!-- mybatis/spring整合包 --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> <version>1.3.1</version> </dependency> </dependencies>
web.xml
<!--主要監聽Spring配置檔案變化--> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring-mybatis.xml</param-value> </context-param> <servlet> <servlet-name>dispatcherServlet</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <!-- 配置SpringMVC下的配置檔案位置及名稱 --> <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>dispatcherServlet</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> <!--配置編碼過濾器,設定編碼：utf-8設定強制編碼--> <filter> <filter-name>encodingFilter</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> <init-param> <param-name>forceEncoding</param-name> <param-value>true</param-value> </init-param> </filter> <!--配置編碼過濾器,設定所有資源--> <filter-mapping> <filter-name>encodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list>
spring-mvc.xml
<!-- 自動掃描controller包下的所有類--> <context:component-scan base-package="com.xiaodou.ssm.controller"/> <mvc:annotation-driven></mvc:annotation-driven> <!-- 配置檢視解析器--> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name = "prefix" value="/WEB-INF/jsp/"></property> <property name = "suffix" value = ".jsp"></property> </bean>
jdbc.properties
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/xiaodou?useUnicode=true&characterEncoding=utf8
jdbc.username=root
jdbc.password=123456
c3p0.maxPoolSize=30
c3p0.minPoolSize=10
c3p0.autoCommitOnClose=false
c3p0.checkoutTimeout=10000
c3p0.acquireRetryAttempts=2spring-mybatis.xml
<!-- 掃描service包下所有使用註解的型別 -->
<context:component-scan base-package="com.xiaodou.ssm.service.impl"/>
<!-- 配置資料庫相關引數properties的屬性：${url} -->
<context:property-placeholder location="classpath:jdbc.properties"/>
<!-- 資料庫連線池 -->
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
<property name="driverClass" value="${jdbc.driver}"/>
<property name="jdbcUrl" value="${jdbc.url}"/>
<property name="user" value="${jdbc.username}"/>
<property name="password" value="${jdbc.password}"/>
<property name="maxPoolSize" value="${c3p0.maxPoolSize}"/>
<property name="minPoolSize" value="${c3p0.minPoolSize}"/>
<property name="autoCommitOnClose" value="${c3p0.autoCommitOnClose}"/>
<property name="checkoutTimeout" value="${c3p0.checkoutTimeout}"/>
<property name="acquireRetryAttempts" value="${c3p0.acquireRetryAttempts}"/>
</bean>
<!-- 配置SqlSessionFactory物件 -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<!-- 注入資料庫連線池 -->
<property name="dataSource" ref="dataSource"/>
<!-- 掃描model包 使用別名 -->
<property name="typeAliasesPackage" value="com.xiaodou.ssm.domain"/>
<!-- 掃描sql配置檔案:mapper需要的xml檔案 -->
<property name="mapperLocations" value="classpath:mapper/*.xml"/>
</bean>
<!-- 配置掃描Dao介面包,動態實現Dao介面,注入到spring容器中 -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<!-- 注入sqlSessionFactory -->
<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
<!-- 給出需要掃描Dao介面包 -->
<property name="basePackage" value="com.xiaodou.ssm.dao"/>
</bean>
<!-- 配置事務管理器 -->
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<!-- 注入資料庫連線池 -->
<property name="dataSource" ref="dataSource"/>
</bean>
<!-- 配置基於註解的宣告式事務 -->
<tx:annotation-driven transaction-manager="transactionManager"/>配置完成後，新增一些示例來測試一下。
在mapper中新增一個UserMapper.xml（Dao和Service在此省略）
<mapper namespace="com.xiaodou.ssm.dao.UserMapper">
<select id="getUserInfo" parameterType="java.lang.String" resultType="com.xiaodou.ssm.domain.User">
select * from user where id=#{id}
</select>
</mapper>新建一個MainController
@Controller
public class MainController {
@RequestMapping("/index")
public ModelAndView index(){
ModelAndView modelAndView = new ModelAndView();
modelAndView.addObject("id","3");
modelAndView.setViewName("index");
return modelAndView;
}
}UserController
@Controller
@RequestMapping("/user")
public class UserController {
@Autowired
private UserService userService;
@RequestMapping("/getUserInfo")
public ModelAndView getUserInfo(String id){
ModelAndView modelAndView = new ModelAndView();
User user = userService.getUserInfo(id);
modelAndView.addObject("user",user);
modelAndView.setViewName("user");
return modelAndView;
}
}執行結果
到此結束，一個最基本的ssm專案搭建完成。
