1、新建maven專案，在pom.xml中新增相關依賴
<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 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>demoGroup</groupId><artifactId>websocket</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>war</packaging> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <!-- 設定 Spring 的版本 --> <spring.version>4.1.2.RELEASE</spring.version> <!-- mybatis版本號 --> <mybatis.version>3.2.8</mybatis.version> <postgresql.driver.version>9.3-1101-jdbc4</postgresql.driver.version> <org.springframework.version>4.1.2.RELEASE</org.springframework.version> <org.slf4j.version>1.6.6</org.slf4j.version> </properties> <dependencies> <!-- junit --> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.12-beta-3</version> <scope>test</scope> </dependency> <!-- log4j --> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>1.2.17</version> </dependency> <dependency> <groupId>jstl</groupId> <artifactId>jstl</artifactId> <version>1.2</version> </dependency> <!-- spring 的基本依賴 開始 --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-expression</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-beans</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aop</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context-support</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-tx</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aspects</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> <version>${spring.version}</version> </dependency> <!-- spring 的基本依賴 結束 --> <!-- mybatis核心包 --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>${mybatis.version}</version> </dependency> <!-- mybatis/spring包 --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> <version>1.2.2</version> </dependency> <!-- postgresql驅動 依賴 --> <dependency> <groupId>org.postgresql</groupId> <artifactId>postgresql</artifactId> <version>${postgresql.driver.version}</version> </dependency> <!-- c3p0連線池 --> <dependency> <groupId>c3p0</groupId> <artifactId>c3p0</artifactId> <version>0.9.1.2</version> </dependency> <!-- Spring WebSocket --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-websocket</artifactId> <version>${org.springframework.version}</version> </dependency> <dependency> <groupId>org.codehaus.jackson</groupId> <artifactId>jackson-mapper-asl</artifactId> <version>1.9.4</version> </dependency> <dependency> <groupId>org.codehaus.jackson</groupId> <artifactId>jackson-core-asl</artifactId> <version>1.9.4</version> </dependency> </dependencies> </project>
2、在java目錄下建立entity、dao、server、controller等主要目錄
3、在resource中建立mapper資料夾，用於存放mybatis的mapper.xml檔案
4、在resource中建立jdbc.properties檔案，用於配置資料庫連線引數
# jdbc要和依賴中的對應
jdbc.driver=org.postgresql.Driver
jdbc.url=jdbc:postgresql://127.0.0.1:5432/dm_video_demo
jdbc.username=postgresql
jdbc.password=123456
5、在resource中建立mybatis.xml檔案
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd"> <configuration> <!-- 配置全域性屬性 --> <settings> <!-- 使用jdbc的getGeneratedKeys獲取資料庫自增主鍵值 --> <setting name="useGeneratedKeys" value="true" /> <!-- 使用列別名替換列名 預設:true --> <setting name="useColumnLabel" value="true" /> <!-- 開啟駝峰命名轉換:Table{a_bc} -> Entity{aBc} --> <setting name="mapUnderscoreToCamelCase" value="true" /> </settings> </configuration>
6、在resource中建立spring_dao.xml檔案
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"> <!-- 配置整合mybatis過程 --> <!-- 1.配置資料庫相關引數properties的屬性：${url} --> <context:property-placeholder location="classpath:jdbc.properties" /> <!-- 2.資料庫連線池 --> <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"> <!-- 配置連線池屬性 --> <property name="driverClass" value="${jdbc.driver}" /> <property name="jdbcUrl" value="${jdbc.url}" /> <property name="user" value="${jdbc.username}" /> <property name="password" value="${jdbc.password}" /> <!-- c3p0連線池的私有屬性 --> <property name="maxPoolSize" value="30" /> <property name="minPoolSize" value="10" /> <!-- 關閉連線後不自動commit --> <property name="autoCommitOnClose" value="false" /> <!-- 獲取連線超時時間 --> <property name="checkoutTimeout" value="10000" /> <!-- 當獲取連線失敗重試次數 --> <property name="acquireRetryAttempts" value="2" /> </bean> <!-- 3.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" /> <!-- MyBaties配置檔案:mybatis.xml --> <property name="configLocation" value="classpath:mybatis.xml" /> <!-- 掃描entity包 使用別名 --> <property name="typeAliasesPackage" value="com.test.entity" /> <!-- 掃描sql配置檔案:mapper需要的xml檔案 --> <property name="mapperLocations" value="classpath:mapper/*.xml" /> </bean> <!-- 4.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.test.dao" /> </bean> </beans>
7、在resource中建立spring_server.xml檔案
<?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.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd"> <!-- 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" /> </beans>
8、在resource中建立spring_mvc.xml檔案
<?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.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd"> <!-- 註解掃描檔案 --> <context:component-scan base-package="com.test.controller"/> <context:component-scan base-package="com.test.dao"/> <context:component-scan base-package="com.test.server"/> <context:component-scan base-package="com.test.socket"/> <!-- 靜態資源放行 --> <mvc:resources location="/static/" mapping="/static/**"/> <!-- 配置SpringMVC --> <!-- 1.開啟SpringMVC註解模式 --> <mvc:annotation-driven /> <!-- 2.靜態資源預設servlet配置 (1)加入對靜態資源的處理：js,gif,png (2)允許使用"/"做整體對映 --> <mvc:default-servlet-handler/> <!-- 3.配置jsp 顯示ViewResolver --> <!-- jsp響應路徑 --> <bean id="viewResolverJsp" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/WEB-INF/jsp/" /> <property name="suffix" value=".jsp" /> <property name="order" value="1"/> </bean> </beans>
9、修改web.xml 檔案
<?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_2_5.xsd" version="2.5"> <display-name>websocket</display-name> <!-- <welcome-file-list> <welcome-file>index.html</welcome-file> <welcome-file>index.htm</welcome-file> <welcome-file>index.jsp</welcome-file> <welcome-file>default.html</welcome-file> <welcome-file>default.htm</welcome-file> <welcome-file>default.jsp</welcome-file> </welcome-file-list>--> <!-- 區分專案名稱，防止重名 --> <context-param> <param-name>websocket</param-name> <param-value>maven.example.root</param-value> </context-param> <!-- Spring的log4j監聽器 --> <listener> <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class> </listener> <!-- 字符集 過濾器 --> <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> <init-param> <param-name>forceEncoding</param-name> <param-value>true</param-value> </init-param> </filter> <filter-mapping> <filter-name>CharacterEncodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- Spring view分發器 --> <servlet> <servlet-name>springMvc</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <!-- 配置需要載入的配置檔案 spring-dao.xml,spring-service.xml,spring-mvc.xml --> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring-*.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <!-- 預設匹配所有的請求 --> <servlet-mapping> <servlet-name>springMvc</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> </web-app>
