jdb 初始化 lsi nco location www. 新人 tis 和我
前不久剛學過ssm框架的使用,在此記錄下來,如果內容有誤歡迎指正!
這篇文章只展示我建立項目的過程,至於各種配置這麽寫的原因在今後的時間裏我會為Spring,Springmvc,mybatis各寫一篇文章進行說明!
創建一個web項目
我使用的是eclipse,相信大多數新手都和我一樣吧,新建web項目就不說了,各位應該都如喝水吃飯一樣熟練了。
導入項目需要的jar包
我是在eclipse中建立的maven項目,因此在pom.xml中寫導入jar包的配置,maven自行下載jar包,目前只會這一種導入jar包的方式。
<dependencies> <!-- Spring MVC --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>4.3.9.RELEASE</version> </dependency> <!-- Spring JDBC --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>4.3.9.RELEASE</version> </dependency> <!-- 單元測試 --> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.12</version> </dependency> <!-- MyBatis --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>3.4.6</version> </dependency> <!-- MyBatis整合Spring --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> <version>1.3.2</version> </dependency> <!-- 數據源/數據庫連接池 --> <dependency> <groupId>commons-dbcp</groupId> <artifactId>commons-dbcp</artifactId> <version>1.4</version> </dependency> <!-- MySQL數據庫連接驅動 --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.8</version> </dependency> <!-- Jackson --> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-databind</artifactId> <version>2.9.7</version> </dependency> <!-- 消息摘要 --> <dependency> <groupId>commons-codec</groupId> <artifactId>commons-codec</artifactId> <version>1.10</version> </dependency> <!-- 文件上傳 --> <dependency> <groupId>commons-fileupload</groupId> <artifactId>commons-fileupload</artifactId> <version>1.3.3</version> </dependency> </dependencies>
編寫web.xml配置文件
打開src/main/webapp/WEB-INF文件夾下的web.xml文件,在其中主要是配置DispatcherServlet,在其中添加如下配置:
<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-*.xml</param-value> <!-- spring配置文件的路徑,根據自己需要選擇路徑 --> </init-param> <load-on-startup>1</load-on-startup> <!-- 初始化優先級為1,使應用啟動時就初始化DispatcherServlet --> </servlet> <servlet-mapping> <servlet-name>SpringMVC</servlet-name> <url-pattern>*.yc</url-pattern> <!-- 需要DispatcherServlet攔截的請求的路徑 --> </servlet-mapping>
編寫Spring配置文件
我習慣將spring文件拆分為3個來寫,分別是spring-mvc.xml,spring-service.xml,spring-dao.xml。
spring-mvc.xml
<?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:jdbc="http://www.springframework.org/schema/jdbc" xmlns:jee="http://www.springframework.org/schema/jee" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:util="http://www.springframework.org/schema/util" xmlns:jpa="http://www.springframework.org/schema/data/jpa" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd http://www.springframework.org/schema/jdbc http://www.springframework.org/schema/jdbc/spring-jdbc-3.2.xsd http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-3.2.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.2.xsd http://www.springframework.org/schema/data/jpa http://www.springframework.org/schema/data/jpa/spring-jpa-1.3.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.2.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-3.2.xsd"> <!-- 組件掃描 --> <context:component-scan base-package="controller" /> <!-- controller所在的包路徑 --> <!-- 配置視圖解析器ViewResolver --> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <!-- 配置前綴 --> <property name="prefix" value="/WEB-INF/" /> <!-- 配置後綴 --> <property name="suffix" value=".jsp" /> <!-- 經過以上配置後, --> <!-- 當前項目中的jsp文件都應該放在/WEB-INF/下 --> </bean> <!-- CommonsMultipartResolver 字符編碼過濾器 --> <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"> <property name="defaultEncoding" value="utf-8" /> </bean> <!-- 註解驅動 --> <mvc:annotation-driven /> </beans>

spring-dao.xml
<?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:jdbc="http://www.springframework.org/schema/jdbc" xmlns:jee="http://www.springframework.org/schema/jee" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:util="http://www.springframework.org/schema/util" xmlns:jpa="http://www.springframework.org/schema/data/jpa" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd http://www.springframework.org/schema/jdbc http://www.springframework.org/schema/jdbc/spring-jdbc-3.2.xsd http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-3.2.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.2.xsd http://www.springframework.org/schema/data/jpa http://www.springframework.org/schema/data/jpa/spring-jpa-1.3.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.2.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-3.2.xsd"> <!-- 讀取db.properties

經過如上配置,這個應用的基本配置就完成了,然後就可以根據配置的位置去寫你的代碼了!
