项目框架图：
1、pom.xml 文件内容
<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/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>spring.mvc.mybatis</groupId> <artifactId>ssm</artifactId> <packaging>war</packaging> <version>0.0.1-SNAPSHOT</version> <name>ssm Maven Webapp</name> <url>http://maven.apache.org</url> <properties> <!-- spring版本号 --> <spring.version>4.0.2.RELEASE</spring.version> <!-- mybatis版本号 --> <mybatis.version>3.2.6</mybatis.version> <!-- log4j日志文件管理包版本 --> <slf4j.version>1.7.7</slf4j.version> <log4j.version>1.2.17</log4j.version> </properties> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.11</version> <!-- 表示开发的时候引入，发布的时候不会加载此包 --> <scope>test</scope> </dependency> <!-- spring核心包 --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</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-oxm</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-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-aop</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-test</artifactId> <version>${spring.version}</version> </dependency> <!-- mybatis核心包 --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>${mybatis.version}</version> </dependency> <!-- mybatis/spring包 --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> <version>1.2.2</version> </dependency> <!-- 导入java ee jar 包 --> <dependency> <groupId>javax</groupId> <artifactId>javaee-api</artifactId> <version>7.0</version> </dependency> <!-- 导入Mysql数据库链接jar包 <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.30</version> </dependency> --> <!-- Oracl数据源 --> <dependency><groupId>com.oracle</groupId><artifactId>ojdbc5</artifactId><version>11.2.0.3</version></dependency> <!-- 导入dbcp的jar包，用来在applicationContext.xml中配置数据库 --> <dependency> <groupId>commons-dbcp</groupId> <artifactId>commons-dbcp</artifactId> <version>1.2.2</version> </dependency> <!-- JSTL标签类 --> <dependency> <groupId>jstl</groupId> <artifactId>jstl</artifactId> <version>1.2</version> </dependency> <!-- 日志文件管理包 --> <!-- log start --> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>${log4j.version}</version> </dependency> <!-- 格式化对象，方便输出日志 --> <dependency> <groupId>com.alibaba</groupId> <artifactId>fastjson</artifactId> <version>1.1.41</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-api</artifactId> <version>${slf4j.version}</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-log4j12</artifactId> <version>${slf4j.version}</version> </dependency> <!-- log end --> <!-- 映入JSON --> <dependency> <groupId>org.codehaus.jackson</groupId> <artifactId>jackson-mapper-asl</artifactId> <version>1.9.13</version> </dependency> <!-- 上传组件包 --> <dependency> <groupId>commons-fileupload</groupId> <artifactId>commons-fileupload</artifactId> <version>1.3.1</version> </dependency> <dependency> <groupId>commons-io</groupId> <artifactId>commons-io</artifactId> <version>2.4</version> </dependency> <dependency> <groupId>commons-codec</groupId> <artifactId>commons-codec</artifactId> <version>1.9</version> </dependency> </dependencies> <build> <finalName>ssm</finalName> </build></project>2、jdbc.properties
driver=oracle.jdbc.driver.OracleDriverurl=jdbc:oracle:thin:@172.16.1.51:1521:yldb username=pospuat2 password=pospuat2 #定义初始连接数 initialSize=0 #定义最大连接数 maxActive=20 #定义最大空闲 maxIdle=20 #定义最小空闲 minIdle=1 #定义最长等待时间 maxWait=60000
3、spring-mybatis.xml 这里先配置mybatis和spring整合，先跟着做吧。
<?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:p="http://www.springframework.org/schema/p" 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-3.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd"> <!-- 自动扫描 @Component @Controller@Service--> <context:component-scan base-package="com.ssm" /> <!-- 引入配置文件 --> <bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> <property name="location" value="classpath:jdbc.properties" /> </bean> <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close"> <property name="driverClassName" value="${driver}" /> <property name="url" value="${url}" /> <property name="username" value="${username}" /> <property name="password" value="${password}" /> <!-- 初始化连接大小 --> <property name="initialSize" value="${initialSize}"></property> <!-- 连接池最大数量 --> <property name="maxActive" value="${maxActive}"></property> <!-- 连接池最大空闲 --> <property name="maxIdle" value="${maxIdle}"></property> <!-- 连接池最小空闲 --> <property name="minIdle" value="${minIdle}"></property> <!-- 获取连接最大等待时间 --> <property name="maxWait" value="${maxWait}"></property> </bean> <!-- spring和MyBatis完美整合，不需要mybatis的配置映射文件 --> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="dataSource" ref="dataSource" /> <!-- 自动扫描mapping.xml文件 --> <property name="mapperLocations" value="classpath:sqlmap/*.xml"></property> </bean> <!-- DAO接口所在包名，Spring会自动查找其下的类 --> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="com.ssm.pospMapper" /> <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property> </bean> <!-- (事务管理)transaction manager, use JtaTransactionManager for global tx --> <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource" /> </bean> </beans> 4、log4j.properties
#定义LOG输出级别 log4j.rootLogger=INFO,Console,File #定义日志输出目的地为控制台 log4j.appender.Console=org.apache.log4j.ConsoleAppender log4j.appender.Console.Target=System.out #可以灵活地指定日志输出格式，下面一行是指定具体的格式 log4j.appender.Console.layout = org.apache.log4j.PatternLayout log4j.appender.Console.layout.ConversionPattern=[%c] - %m%n #文件大小到达指定尺寸的时候产生一个新的文件 log4j.appender.File = org.apache.log4j.RollingFileAppender #指定输出目录 log4j.appender.File.File = logs/ssm.log #定义文件最大大小 log4j.appender.File.MaxFileSize = 10MB # 输出所以日志，如果换成DEBUG表示输出DEBUG以上级别日志 log4j.appender.File.Threshold = ALL log4j.appender.File.layout = org.apache.log4j.PatternLayout log4j.appender.File.layout.ConversionPattern =[%p] [%d{yyyy-MM-dd HH\:mm\:ss}][%c]%m%n 5、现在配置好了可以做一些测试。需要写service、DAO等。自己写比较麻烦，我选择自动生成。
好吧。我们还要先建表：ORACLE数据库，数据库自己建吧。建表语句如下
-- Create tablecreate table PFB_PAYMENT_ORDER_INFO( ID VARCHAR2(32) not null, PAYMENT_ORDER_CODE VARCHAR2(32) not null, BILL_ORDER_DATA_ID VARCHAR2(32) not null, CHANNEL_CODE VARCHAR2(32) not null, ITEM_CODE VARCHAR2(32) not null, ORDER_AMOUNT NUMBER(12,2) not null, FEE_AMOUNT NUMBER(12,2), PAYMENT_CHANNEL VARCHAR2(32) not null, PAYMENT_CHANNEL_CODE VARCHAR2(32), PAY_CHANNEL_ORDER VARCHAR2(32), ORDER_STATUS VARCHAR2(8) not null, CREATE_DATE CHAR(20) not null, UPDATE_DATE CHAR(20) not null, MACHINE_NUMBER VARCHAR2(40) not null, PAYMENT_TIME CHAR(20), BUSINESS_CODE VARCHAR2(32));-- Add comments to the columns comment on column PFB_PAYMENT_ORDER_INFO.ID is 'uuid';comment on column PFB_PAYMENT_ORDER_INFO.PAYMENT_ORDER_CODE is '支付订单号';comment on column PFB_PAYMENT_ORDER_INFO.BILL_ORDER_DATA_ID is '账单订单号';comment on column PFB_PAYMENT_ORDER_INFO.CHANNEL_CODE is '渠道号';comment on column PFB_PAYMENT_ORDER_INFO.ITEM_CODE is '机构项目编号';comment on column PFB_PAYMENT_ORDER_INFO.ORDER_AMOUNT is '订单缴费金额（分）';comment on column PFB_PAYMENT_ORDER_INFO.FEE_AMOUNT is '手续费（分）';comment on column PFB_PAYMENT_ORDER_INFO.PAYMENT_CHANNEL is '支付方式（1微信，2支付宝，3 申鑫扫码微信，4 申鑫扫码支付宝，5 欣客扫码微信，6 欣客扫码支付宝）';comment on column PFB_PAYMENT_ORDER_INFO.PAYMENT_CHANNEL_CODE is '支付机构号';comment on column PFB_PAYMENT_ORDER_INFO.PAY_CHANNEL_ORDER is '支付流水号';comment on column PFB_PAYMENT_ORDER_INFO.ORDER_STATUS is '订单支付状态(F 付款失败,S 付款成功,I 待付款,P 付款中)';comment on column PFB_PAYMENT_ORDER_INFO.CREATE_DATE is '创建时间';comment on column PFB_PAYMENT_ORDER_INFO.UPDATE_DATE is '更新时间';comment on column PFB_PAYMENT_ORDER_INFO.MACHINE_NUMBER is '机表号billkey';comment on column PFB_PAYMENT_ORDER_INFO.PAYMENT_TIME is '发货更新时间';comment on column PFB_PAYMENT_ORDER_INFO.BUSINESS_CODE is '商户号';-- Create/Recreate primary, unique and foreign key constraints alter table PFB_PAYMENT_ORDER_INFO add constraint PFB_PAYMENT_ORDER_INFO_PK primary key (ID) using index;
6、自动生成MyBatis DAO、脚本文件需要工具，地址如下：
http://download.csdn.net/detail/q260996583/9906043
解压后打开 ..\mybatis-generator-core-1.3.2\lib\generatorConfig.xml
<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE generatorConfiguration PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN" "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd"><generatorConfiguration> <classPathEntry location="ojdbc14.jar"/> <context id="DB2Tables" targetRuntime="MyBatis3"> <commentGenerator> <property name="suppressDate" value="true"/> <property name="suppressAllComments" value="true"/> </commentGenerator> <jdbcConnection driverClass="oracle.jdbc.driver.OracleDriver" connectionURL="jdbc:oracle:thin:@172.16.1.51:1521:yldb" userId="pospuat2" password="pospuat2"> </jdbcConnection> <javaTypeResolver> <property name="forceBigDecimals" value="false"/> </javaTypeResolver><!-- 建立java文件夹 --> <javaModelGenerator targetPackage="com.ssm.entity" targetProject="E:\iTudou\java"> <property name="enableSubPackages" value="true"/> <property name="trimStrings" value="true"/> </javaModelGenerator><!-- 建立resources文件夹 --> <sqlMapGenerator targetPackage="sqlmap" targetProject="E:\iTudou\resources"> <property name="enableSubPackages" value="true"/> </sqlMapGenerator> <javaClientGenerator type="XMLMAPPER" targetPackage="com.ssm.pospMapper" targetProject="E:\iTudou\java"> <property name="enableSubPackages" value="true"/> </javaClientGenerator><!-- 表名，和类名 --> <table tableName="PFB_PAYMENT_ORDER_INFO" domainObjectName="PFBPAYMENTORDERINFODO"></table> </context></generatorConfiguration>
红色部分按需填写 mybatis-generator-core-1.3.2\lib\run.bat 运行后可以得到相应文件 copy到项目中
7、建立service
package com.ssm.business.service.impl;import java.util.List;import javax.annotation.Resource;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Service;import com.ssm.business.service.interfaces.IPaymentOrderInfoSV;import com.ssm.entity.PFBPAYMENTORDERINFODO;import com.ssm.entity.PFBPAYMENTORDERINFODOExample;import com.ssm.pospMapper.PFBPAYMENTORDERINFODOMapper;@Servicepublic class PaymentOrderInfoSVImpl implements IPaymentOrderInfoSV {@AutowiredPFBPAYMENTORDERINFODOMapper mapper;public List<PFBPAYMENTORDERINFODO> selectByExample(PFBPAYMENTORDERINFODOExample example) {return mapper.selectByExample(example);}}接口：
package com.ssm.business.service.interfaces;import java.util.List;import com.ssm.entity.PFBPAYMENTORDERINFODO;import com.ssm.entity.PFBPAYMENTORDERINFODOExample;public interface IPaymentOrderInfoSV {List<PFBPAYMENTORDERINFODO> selectByExample(PFBPAYMENTORDERINFODOExample example);}8、SpringMVC 加入
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:p="http://www.springframework.org/schema/p" 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-3.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd"> <!-- 自动扫描该包，使SpringMVC认为包下用了@controller注解的类是控制器 --> <context:component-scan base-package="com.ssm.business.action" /> <!--避免IE执行AJAX时，返回JSON出现下载文件 --> <bean id="mappingJacksonHttpMessageConverter" class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter"> <property name="supportedMediaTypes"> <list> <value>text/html;charset=UTF-8</value> </list> </property> </bean> <!-- 启动SpringMVC的注解功能，完成请求和注解POJO的映射 --> <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"> <property name="messageConverters"> <list> <ref bean="mappingJacksonHttpMessageConverter" /> <!-- JSON转换器 --> </list> </property> </bean> <!-- 定义跳转的文件的前后缀 ，视图模式配置--> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <!-- 这里的配置我的理解是自动给后面action的方法return的字符串加上前缀和后缀，变成一个 可用的url地址 --> <property name="prefix" value="/WEB-INF/" /> <property name="suffix" value=".jsp" /> </bean> <!-- 配置文件上传，如果没有使用文件上传可以不用配置，当然如果不配，那么配置文件中也不必引入上传组件包 --> <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"> <!-- 默认编码 --> <property name="defaultEncoding" value="utf-8" /> <!-- 文件大小最大值 --> <property name="maxUploadSize" value="10485760000" /> <!-- 内存中的最大值 --> <property name="maxInMemorySize" value="40960" /> </bean> </beans>
9、配置web.xml文件
<?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_3_0.xsd" version="3.0"> <display-name>Archetype Created Web Application</display-name> <!-- Spring和mybatis的配置文件 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring-mybatis.xml</param-value> </context-param> <!-- 编码过滤器 --> <filter> <filter-name>encodingFilter</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <async-supported>true</async-supported> <init-param> <param-name>encoding</param-name> <param-value>UTF-8</param-value> </init-param> </filter> <filter-mapping> <filter-name>encodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- Spring监听器 --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- 防止Spring内存溢出监听器 --> <listener> <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class> </listener> <!-- Spring MVC servlet --> <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-mvc.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> <async-supported>true</async-supported> </servlet> <servlet-mapping> <servlet-name>SpringMVC</servlet-name> <!-- 此处可以可以配置成*.do，对应struts的后缀习惯 --> <url-pattern>/</url-pattern> </servlet-mapping> <welcome-file-list> <welcome-file>/index.jsp</welcome-file> </welcome-file-list></web-app>
10、Controller搭建
package com.ssm.business.action;import java.util.List;import javax.servlet.http.HttpServletRequest;import org.apache.log4j.Logger;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Controller;import org.springframework.ui.Model;import org.springframework.web.bind.annotation.RequestMapping;import com.ssm.business.service.interfaces.IPaymentOrderInfoSV;import com.ssm.entity.PFBPAYMENTORDERINFODO;import com.ssm.entity.PFBPAYMENTORDERINFODOExample;@Controller @RequestMapping("/payment")public class PaymentOrderController {private static Logger logger = Logger.getLogger(PaymentOrderController.class); @AutowiredIPaymentOrderInfoSV service;@RequestMapping("/showPayment") public String showPayment(HttpServletRequest request,Model model){ String channelCode = request.getParameter("channelCode"); PFBPAYMENTORDERINFODOExample example = new PFBPAYMENTORDERINFODOExample();example.createCriteria().andChannelCodeEqualTo(channelCode); List<PFBPAYMENTORDERINFODO> paymentDO = service.selectByExample(example); for(PFBPAYMENTORDERINFODO payDo : paymentDO) {logger.info(payDo.getId() + ":" + payDo.getChannelCode());} model.addAttribute("payment", paymentDO); return "show"; } }<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%><!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"><html><head><meta http-equiv="Content-Type" content="text/html; charset=UTF-8"><title>Insert title here</title></head><body>返回：${payment }</body></html>测试吧，数据库自己插几条数据进件，将项目放到tomcat中启动。访问地址如下。http://localhost:8080/ssm/payment/showPayment?channelCode=abc
