easyui+spring+springmvc+ibatis學習（一）

使用easyui+spring+springmvc+ibatis搭建一個管理系統的專案，效果圖如下：
首先，基於建立一個maven工程，轉換為web專案，我的專案結構如下：
我使用的是jetty伺服器，jetty的配置檔案如下：
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE Configure PUBLIC "-//Mort Bay Consulting//DTD Configure//EN" "http://jetty.mortbay.org/configure.dtd"> <Configure id="Serve" class="org.mortbay.jetty.Server"> <Call name="addConnector"> <Arg> <New class="org.mortbay.jetty.nio.SelectChannelConnector"> <Set name="host"><SystemProperty name="jetty.host" /></Set> <Set name="port"><SystemProperty name="jetty.port" default="9090"/></Set> </New> </Arg> </Call> </Configure>
在pom.xml中引入相關的jar包，web.xml的配置如下：
<?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" id="WebApp_ID" version="2.5"> <!-- 應用程式名 --> <display-name>easyui</display-name> <!-- 應用程式描述說明文字 --> <description>spring springmvc ibatis easyui</description> <!-- ServletContext初始化引數 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicationContext.xml</param-value> </context-param> <context-param> <param-name>log4jConfigLocation</param-name> <param-value>classpath:log4j.properties</param-value> </context-param> <!-- 預設起始頁面 --> <welcome-file-list> <!--welcome-file-list一般情況下只能使用靜態網頁，如果非要把他配置成SpringMVC的控制器URL就會報錯. --> <welcome-file>login.jsp</welcome-file> </welcome-file-list> <!-- spring security 過濾器 <filter> <filter-name>springSecurityFilterChain</filter-name> <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class> </filter> <filter-mapping> <filter-name>springSecurityFilterChain</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> --> <!-- 配置監聽器，用於初始化 --> <listener> <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class> </listener> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!--Servlet初始化引數，配置springmvc特性 --> <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:springmvc-servlet.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>springmvc</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> <!-- 登陸過濾 --> <filter> <filter-name>LoginFilter</filter-name> <filter-class>com.cjb.test.filter.MyLoginFilter</filter-class> </filter> <filter-mapping> <filter-name>LoginFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> </web-app>
spring的配置檔案applicationContext.xml的配置如下：
<?xml version="1.0" encoding="UTF-8"?> <!-- Spring框架配置檔案 --> <!-- 配置ContextLoaderListener表示，該工程要以spring的方式啟動。啟動時會預設在/WEB-INF目錄下查詢applicationContext.xml 作為spring容器的配置檔案，這裡可以初始化一些bean，如DataSource和iBATIS的整合 --> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd <span style="white-space:pre"> </span>http://www.springframework.org/schema/aop <span style="white-space:pre"> </span>http://www.springframework.org/schema/aop/spring-aop-3.0.xsd" default-autowire="byName"> <!-- 自動掃描 所有註解 註冊為bean (啟動註解)--> <context:component-scan base-package="com.cjb.test"> <!-- 自動掃描元件，這裡要把web下面的 controller去除，他們是在springmvc-servlet.xml中配置的，如果不去除會影響事務管理的。--> <span style="white-space:pre"> </span><context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/> </context:component-scan> <span style="white-space:pre"> </span><!-- DataSource定義 --> <span style="white-space:pre"> </span><bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"> <span style="white-space:pre"> </span><property name="driverClassName" value="oracle.jdbc.driver.OracleDriver" /> <span style="white-space:pre"> </span><property name="url" value="jdbc:oracle:thin:@127.0.0.1:1521:XE"/> <span style="white-space:pre"> </span><property name="username" value="chengjunbo" /> <span style="white-space:pre"> </span><property name="password" value="chengjunbo" /> <span style="white-space:pre"> </span><property name="maxActive" value="50" /> <span style="white-space:pre"> </span><property name="maxIdle" value="5" /> <span style="white-space:pre"> </span><property name="maxWait" value="5000" /> <span style="white-space:pre"> </span><property name="removeAbandoned" value="true" /> <span style="white-space:pre"> </span><property name="removeAbandonedTimeout" value="5" /> <span style="white-space:pre"> </span></bean> <span style="white-space:pre"> </span><!-- 配置事務管理器--> <span style="white-space:pre"> </span><bean id="transactionManager" <span style="white-space:pre"> </span>class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <span style="white-space:pre"> </span><property name="dataSource" ref="dataSource" /> <span style="white-space:pre"> </span></bean> <!-- 啟動spring事務註解，事務註解盡在此 --> <tx:annotation-driven transaction-manager="transactionManager"/> <span style="white-space:pre"> </span><bean id="transactionTemplate" <span style="white-space:pre"> </span>class="org.springframework.transaction.support.TransactionTemplate"> <span style="white-space:pre"> </span><property name="transactionManager" ref="transactionManager" /> <span style="white-space:pre"> </span></bean> <span style="white-space:pre"> </span><!-- 配置SqlMapClient物件 --> <span style="white-space:pre"> </span><bean id="sqlMapClient" class="org.springframework.orm.ibatis.SqlMapClientFactoryBean"> <span style="white-space:pre"> </span><property name="dataSource" ref="dataSource" /> <span style="white-space:pre"> </span><property name="configLocation" value="classpath:sql-map-config.xml"/> <span style="white-space:pre"> </span></bean> <!--根據sqlMapClien建立一個SqlMapClient模版類--> <bean id="sqlMapClientTemplate" class="org.springframework.orm.ibatis.SqlMapClientTemplate"> <span style="white-space:pre"> </span><property name="sqlMapClient" ref="sqlMapClient"/> </bean> </beans>
springmvc的配置檔案springmvc-servlet.xml的配置如下：
<?xml version="1.0" encoding="UTF-8"?>
<!--springmvc-servlet.xml(Springmvc框架配置檔案)該檔案是springmvc框架配置檔案，也是它的核心檔案 -->
<!-- Bean頭部
配置DispatcherServlet表示，該工程將採用springmvc的方式。啟動時也會預設在/WEB-INF目錄下查詢XXX-servlet.xml作為配置檔案，
XXX就是DispatcherServlet的名字，該檔案中將配置兩項重要的mvc特性：
HandlerMapping,負責為DispatcherServlet這個前端控制器的請求查詢Controller；
ViewResolver,負責為DispatcherServlet查詢ModelAndView的檢視解析器
