二、spring-mybatis.xmlcss
1 <?xml version="1.0" encoding="UTF-8"?> 2 <beans xmlns="http://www.springframework.org/schema/beans" 3 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" 4 xmlns:tx="http://www.springframework.org/schema/tx" xmlns:aop="http://www.springframework.org/schema/aop" 5 xsi:schemaLocation="http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.2.xsd 6 http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd 7 http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.2.xsd 8 http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.2.xsd"> 9 <!-- 自動掃描 --> 10 <context:component-scan base-package="com.jdw" /> 11 <!-- 引入配置文件 --> 12 <bean id="propertyConfigurer" 13 class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> 14 <property name="location" value="classpath:jdbc.properties" /> 15 </bean> 16 17 <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" 18 destroy-method="close"> 19 <property name="driverClassName" value="${driver}" /> 20 <property name="url" value="${url}" /> 21 <property name="username" value="${username}" /> 22 <property name="password" value="${password}" /> 23 <!-- 初始化鏈接大小 --> 24 <property name="initialSize" value="${initialSize}"></property> 25 <!-- 鏈接池最大數量 --> 26 <property name="maxActive" value="${maxActive}"></property> 27 <!-- 鏈接池最大空閒 --> 28 <property name="maxIdle" value="${maxIdle}"></property> 29 <!-- 鏈接池最小空閒 --> 30 <property name="minIdle" value="${minIdle}"></property> 31 <!-- 獲取鏈接最大等待時間 --> 32 <property name="maxWait" value="${maxWait}"></property> 33 </bean> 34 35 <!-- spring和MyBatis完美整合，不須要mybatis的配置映射文件 --> 36 <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> 37 <property name="dataSource" ref="dataSource" /> 38 <!-- 39 <property name="configLocation" value="classpath:SqlMapConfig.xml" /> --> 40 <!-- 自動掃描mapping.xml文件 --> 41 <property name="mapperLocations" value="classpath:com/jdw/mapping/*.xml"></property> 42 43 <property name="plugins"> 44 <array> 45 <bean class="com.github.pagehelper.PageHelper"> 46 <property name="properties"> 47 <value> 48 dialect=mysql 49 </value> 50 </property> 51 </bean> 52 </array> 53 </property> 54 </bean> 55 56 <!-- DAO接口所在包名，Spring會自動查找其下的類 --> 57 <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> 58 <property name="basePackage" value="com.jdw.dao" /> 59 <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property> 60 </bean> 61 62 <!-- ================================事務相關控制================================================= --> 63 <bean name="transactionManager" 64 class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> 65 <property name="dataSource" ref="dataSource"></property> 66 </bean> 67 68 <tx:advice id="userTxAdvice" transaction-manager="transactionManager"> 69 <tx:attributes> 70 <tx:method name="delete*" propagation="REQUIRED" read-only="false" 71 rollback-for="java.lang.Exception" no-rollback-for="java.lang.RuntimeException" /> 72 <tx:method name="insert*" propagation="REQUIRED" read-only="false" 73 rollback-for="java.lang.RuntimeException" /> 74 <tx:method name="update*" propagation="REQUIRED" read-only="false" 75 rollback-for="java.lang.Exception" /> 76 77 <tx:method name="find*" propagation="SUPPORTS" /> 78 <tx:method name="get*" propagation="SUPPORTS" /> 79 <tx:method name="select*" propagation="SUPPORTS" /> 80 </tx:attributes> 81 </tx:advice> 82 83 <aop:config> 84 <aop:pointcut id="pc" 85 expression="execution(public * com.jdw.service.*.*(..))" /> <!--把事務控制在Service層 --> 86 <aop:advisor pointcut-ref="pc" advice-ref="userTxAdvice" /> 87 </aop:config> 88 89 </beans>
三、spring-mvc.xmlhtml
<?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/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.2.xsd 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-4.2.xsd"> <!-- <mvc:view-controller path="/" view-name="index" /> --> <mvc:default-servlet-handler /> <!-- 自動掃描該包，使SpringMVC認爲包下用了@controller註解的類是控制器 --> <context:component-scan base-package="com.jdw.controller" /> <!-- 啓用默認配置 --> <mvc:annotation-driven> <mvc:message-converters register-defaults="true"> <!-- 配置Fastjson支持 --> <bean class="com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter"> <property name="supportedMediaTypes" > <array> <value>text/html;charset=UTF-8</value> <value>application/json</value> </array> </property> <property name="features"> <array> <value>WriteMapNullValue</value> <value>WriteNullStringAsEmpty</value> </array> </property> </bean> </mvc:message-converters> </mvc:annotation-driven> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <!-- 這裏的配置個人理解是自動給後面action的方法return的字符串加上前綴和後綴，變成一個 可用的url地址 --> <property name="prefix" value="/WEB-INF/" /> <property name="suffix" value=".jsp" /> </bean> <!-- 配置文件上傳，若是沒有使用文件上傳能夠不用配置，固然若是不配，那麼配置文件中也沒必要引入上傳組件包 --> <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"> <!-- 默認編碼 --> <property name="defaultEncoding" value="utf-8" /> <!-- 文件大小最大值 --> <property name="maxUploadSize" value="10485760000" /> <!-- 內存中的最大值 --> <property name="maxInMemorySize" value="40960" /> </bean> </beans>
四、service代碼java
@Override public Map<String,Object> query(String type, Integer pageNo, Integer pageSize) { pageNo = pageNo == null?1:pageNo; pageSize = pageSize == null?10:pageSize; PageHelper.startPage(pageNo, pageSize); List<Category> list = this.dao.selectCategoryByType(type); for(Category c:list) { System.out.println(c); } //用PageInfo對結果進行包裝 PageInfo<Category> page = new PageInfo<Category>(list); //測試PageInfo所有屬性 /* System.out.println(page.getPageNum()); System.out.println(page.getPageSize()); System.out.println(page.getStartRow()); System.out.println(page.getEndRow()); System.out.println(page.getTotal()); System.out.println(page.getPages()); System.out.println(page.getFirstPage()); System.out.println(page.getLastPage()); System.out.println(page.isHasPreviousPage()); System.out.println(page.isHasNextPage());*/ Map<String, Object> map=new HashMap<String, Object>(); map.put("total", page.getTotal()); map.put("rows", page.getList()); return map; }
五、controller代碼mysql
@ResponseBody @RequestMapping(value = "/list") public Map<String, Object> getCategories(HttpServletRequest request,HttpServletResponse response) { int page=Integer.parseInt(request.getParameter("page")); int rows=Integer.parseInt(request.getParameter("rows")); String type=request.getParameter("type"); return categoryService.query(type, page, rows); }
六、easyui調用jquery
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <%@ include file="/public/head.jspf"%> <style type="text/css"> body { margin: 1px; } .searchbox { margin: -3; } </style> <script type="text/javascript"> $(function() { $('#dg') .datagrid( { url : '${shop}/category/list', //width:250, idField : 'id', pageSize : 5, pageList : [ 5, 10, 15, 20, 25 ], queryParams : { type : '' }, striped : true, nowrap : true, fitColumns : true, singleSelect : false, pagination : true, toolbar : [ { iconCls : 'icon-add', text : '添加類別', handler : function() { parent .$("#win") .window( { title : '添加類別', width : 400, height : 300, content : '<iframe src="send_category_add.action" frameborder="0" width="100%" height="100%" />' }); } }, '-', { iconCls : 'icon-edit', text : '更新類別', handler : function() { var rows = $("#dg").datagrid( "getSelections"); if (rows.length != 1) { $.messager.show({ title : '錯誤提示', msg : '一次只能更新一條記錄。', timeout : 5000, showType : 'slide' }); } else { parent .$("#win") .window( { title : '更新類別', width : 400, height : 240, content : '<iframe src="send_category_update.action" frameborder="0" width="100%" height="100%" />' }); } } }, '-', { iconCls : 'icon-remove', text : '刪除類別', handler : function() { var rows = $("#dg").datagrid( "getSelections"); if (rows.length == 0) { $.messager.show({ title : '錯誤提示', msg : '至少選中一條記錄。', timeout : 5000, showType : 'slide' }); } else { $.messager .confirm( '刪除確認對話框', '是否刪除選中記錄？', function(r) { if (r) { var ids = ""; for (var i = 0; i < rows.length; i++) { ids += rows[i].id + ","; } ids = ids .substring( 0, ids .lastIndexOf(',')); $ .post( "category_deleteByIds.action", { ids : ids }, function( result) { if (result == "true") { //取消選中的全部行 $( "#dg") .datagrid( 'uncheckAll'); $( "#dg") .datagrid( 'reload'); } else { $.messager .show({ title : '刪除異常', msg : '刪除失敗，請檢查操做。', timeout : 5000, showType : 'slide' }); } }, 'text'); } }); } } }, '-', { text : "<input id='ss' name='search' />" } ], rowStyler : function(index, row) { if (index % 2 == 0) { return 'background-color:#6293BB;color:#fff;'; } }, frozenColumns : [ [ { field : 'xyz', checkbox : true }, { field : 'cId', title : '編號', width : 100 } ] ], columns : [ [ { field : 'cName', title : '類別', width : 100, formatter : function(value, row, index) { return "<span title="+value+">" + value + "</span>"; } }, { field : 'hot', title : '熱點', width : 100, align : 'center', formatter : function(value, row, index) { if (value) return "<input type='checkbox' checked disabled='true' />"; else return "<input type='checkbox' disabled='true' />"; } /* styler : function(value, row, index) { if (value < 20) { return 'background-color:#ffee00;color:red;'; } }*/ } ] ] }); $('#ss').searchbox({ searcher : function(value, name) { $('#dg').datagrid('load', { type : value }); }, prompt : 'sssssss' }); }); </script> </head> <body> <table id="dg"></table> </body> </html>
七、總結說明git
（1）注意bean的getter、setter寫法，不能這麼寫getcName,要這麼寫getCName,不然fastjson會找不到cName屬性github
（2）暫時不要用fastjson 1.2.10,有bug.會拋出 java.lang.AbstractMethodError異常web
（3）<mvc:default-servlet-handler />處理靜態資源，不要用mvc:resources，很差用，容易出問題；spring
（4）靜態資源最好用以下方式:
head.jspf：
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%> <c:set value="${pageContext.request.contextPath }" var="shop" /> <title>my website</title> <link rel="stylesheet" href="${shop}/jquery-easyui-1.3.5/themes/default/easyui.css" type="text/css" /> <link rel="stylesheet" href="${shop}/jquery-easyui-1.3.5/themes/icon.css" type="text/css" /> <script type="text/javascript" src="${shop}/jquery-easyui-1.3.5/jquery.min.js"></script> <script type="text/javascript" src="${shop}/jquery-easyui-1.3.5/jquery.easyui.min.js"></script> <script type="text/javascript" src="${shop}/jquery-easyui-1.3.5/locale/easyui-lang-zh_CN.js"></script>
其餘頁面：
<head> <%@ include file="/public/head.jspf"%> </head>
