时间：2023-11-24 11:39:52

博主初学SSM时记录的搭建过程

开发工具：eclipse开发环境：jdk1.8+tomcat8.5+maven数据库：MySQL

1、创建maven项目（webapp）

2、导入依赖（Spring 4.0.2 RELEASE+Spring MVC 4.0.2 RELEASE+MyBatis 3.2.6）

<project xmlns="/POM/4.0.0" xmlns:xsi="/2001/XMLSchema-instance" xsi:schemaLocation="/POM/4.0.0 /xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><groupId>com</groupId><artifactId>ssm</artifactId><version>0.0.1-SNAPSHOT</version><name>SSM</name><url></url><properties> <spring.version>4.0.2.RELEASE</spring.version>  <mybatis.version>3.2.6</mybatis.version>  <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>  <scope>test</scope> </dependency>  <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>${spring.version}</version> </dependency>  <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>${mybatis.version}</version> </dependency>  <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> <version>1.2.2</version> </dependency> <dependency><groupId>org.mybatis.generator</groupId><artifactId>mybatis-generator-core</artifactId><version>1.3.2</version></dependency> <dependency> <groupId>javax</groupId> <artifactId>javaee-api</artifactId> <version>7.0</version> </dependency>  <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.30</version> </dependency>  <dependency> <groupId>commons-dbcp</groupId> <artifactId>commons-dbcp</artifactId> <version>1.2.2</version> </dependency>  <dependency> <groupId>jstl</groupId> <artifactId>jstl</artifactId> <version>1.2</version> </dependency>   <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>${log4j.version}</version> </dependency>  <dependency> <groupId>com.alibaba</groupId> <artifactId>fastjson</artifactId> <version>1.1.41</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-api</artifactId> <version>${slf4j.version}</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-log4j12</artifactId> <version>${slf4j.version}</version> </dependency>   <dependency> <groupId>org.codehaus.jackson</groupId> <artifactId>jackson-mapper-asl</artifactId> <version>1.9.13</version> </dependency>  <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>

3、Spring与MyBatis的整合

1）建立JDBC属性文件（jdbc.properties）

jdbc.driver=com.mysql.jdbc.Driverjdbc.url=jdbc:mysql://localhost:3306/db_ssmjdbc.username=rootjdbc.password=123456#定义初始连接数 jdbc.initialSize=0 #定义最大连接数 jdbc.maxActive=20 #定义最大空闲 jdbc.maxIdle=20 #定义最小空闲 jdbc.minIdle=1 #定义最长等待时间 jdbc.maxWait=60000

2）建立spring-mybatis.xml配置文件

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="/schema/beans" xmlns:xsi="/2001/XMLSchema-instance" xmlns:p="/schema/p" xmlns:context="/schema/context" xmlns:mvc="/schema/mvc" xsi:schemaLocation="/schema/beans /schema/beans/spring-beans-3.1.xsd /schema/context /schema/context/spring-context-3.1.xsd /schema/mvc /schema/mvc/spring-mvc-4.0.xsd"> <context:component-scan base-package=".hnust"></context:component-scan><bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"><property name="location" value="classpath:jdbc.properties"/></bean><bean id="dataSource" class="mons.dbcp.BasicDataSource" destroy-method="close"> <property name="driverClassName" value="${jdbc.driver}" /> <property name="url" value="${jdbc.url}" /> <property name="username" value="${jdbc.username}" /> <property name="password" value="${jdbc.password}" />  <property name="initialSize" value="${jdbc.initialSize}"></property>  <property name="maxActive" value="${jdbc.maxActive}"></property>  <property name="maxIdle" value="${jdbc.maxIdle}"></property>  <property name="minIdle" value="${jdbc.minIdle}"></property>  <property name="maxWait" value="${jdbc.maxWait}"></property> </bean><bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"><property name="dataSource" ref="dataSource"/><property name="mapperLocations" value="classpath:com/cn/hnust/mapper/*.xml"></property></bean><bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"><property name="basePackage" value=".hnust.mapper"/><property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property></bean><bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"><property name="dataSource" ref="dataSource"/></bean></beans>

3）Log4j的配置（log4j.properties）——非必须

#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

4、创建测试表

DROP TABLE IF EXISTS `user_t`; CREATE TABLE `user_t` ( `id` int(11) NOT NULL AUTO_INCREMENT, `user_name` varchar(40) NOT NULL, `password` varchar(255) NOT NULL, `age` int(4) NOT NULL, PRIMARY KEY (`id`) ) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8; /*Data for the table `user_t` */

5、generatorConfig.xml的配置——自动生成代码

1）pom.xml文件中添加依赖包及插件

dependencies中添加：

<dependency><groupId>org.mybatis.generator</groupId><artifactId>mybatis-generator-core</artifactId><version>1.3.2</version></dependency>

在build的plugins中添加：

<plugin><groupId>org.mybatis.generator</groupId><artifactId>mybatis-generator-maven-plugin</artifactId><version>1.3.2</version><configuration><configurationFile>src/main/resources/generatorConfig.xml</configurationFile><verbose>true</verbose><overwrite>true</overwrite></configuration></plugin>

2）generatorConfig.xml

<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE generatorConfiguration PUBLIC "-////DTD MyBatis Generator Configuration 1.0//EN" "/dtd/mybatis-generator-config_1_0.dtd"><generatorConfiguration><classPathEntry location="C:\Users\44839\.m2\repository\mysql\mysql-connector-java\5.1.30\mysql-connector-java-5.1.30.jar"/><context id="my" targetRuntime="MyBatis3"><commentGenerator><property name="suppressDate" value="true"/><property name="suppressAllComments" value="true"/></commentGenerator><jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://localhost:3306/db_ssm" userId="root" password="123456"/><javaModelGenerator targetPackage=".hnust.model" targetProject="src/main/java"><property name="enableSubPackages" value="true"/><property name="trimStrings" value="true"/></javaModelGenerator><sqlMapGenerator targetPackage=".hnust.mapper" targetProject="src/main/resources"><property name="enableSubPackages" value="true"/></sqlMapGenerator><javaClientGenerator type="XMLMAPPER" targetPackage=".hnust.mapper" targetProject="src/main/java"><property name="enableSubPackages" value="true"/></javaClientGenerator><table tableName="user_t" domainObjectName="User" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table></context></generatorConfiguration>

3）在ecplise中使用，则右击工程，maven build，添加命令mybatis-generator:generate，代码生成完毕！

6、建立Service接口和实现类

1）IUserService.java

package .hnust.service;import .hnust.model.User;public interface IUserService {public User getUserById(int userId);}

2）UserServiceImpl.java

package .hnust.service.impl;import javax.annotation.Resource;import org.springframework.stereotype.Service;import .hnust.mapper.UserMapper;import .hnust.model.User;import .hnust.service.IUserService;@Service("userService")public class UserServiceImpl implements IUserService{@Resourceprivate UserMapper userDao;@Overridepublic User getUserById(int userId) {return this.userDao.selectByPrimaryKey(userId);}}

3）目录结构

7、建立测试类

测试类在src/test/java中建立，下面测试类中注释掉的部分是不使用Spring时，一般情况下的一种测试方法；如果使用了Spring那么就可以使用注解的方式来引入配置文件和类，然后再将service接口对象注入，就可以进行测试了。

如果测试成功，表示Spring和Mybatis已经整合成功了。输出信息使用的是Log4j打印到控制台。

package org.zsl.testMybatis;import javax.annotation.Resource;import org.apache.log4j.Logger;import org.junit.Test;import org.junit.runner.RunWith;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;import org.springframework.test.context.ContextConfiguration;import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;import com.alibaba.fastjson.JSON;import .hnust.model.User;import .hnust.service.IUserService;@RunWith(SpringJUnit4ClassRunner.class) //表示继承了SpringJUnit4ClassRunner类@ContextConfiguration(locations= {"classpath:spring-mybatis.xml"})public class TestMyBatis {private static Logger logger=Logger.getLogger(TestMyBatis.class);//private ApplicationContext ac=null;@Resourceprivate IUserService userService=null;//@Before//public void Before() {//ac=new ClassPathXmlApplicationContext("applicationContext.xml");//userService=(IUserService)ac.getBean("BeanService");//}@Testpublic void test1() {User user=userService.getUserById(1);//System.out.println(user.getUserName());//logger.info("值:"+user.getUserName());logger.info(JSON.toJSON(user));}}

8、Spring MVC的整合

Spring MVC单独配置，然后在web.xml中整合配置

1）配置spring-mvc.xml(主要是自动扫描控制器，视图模式，注解启动)

<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="/schema/beans" xmlns:xsi="/2001/XMLSchema-instance" xmlns:p="/schema/p" xmlns:context="/schema/context" xmlns:mvc="/schema/mvc" xsi:schemaLocation="/schema/beans /schema/beans/spring-beans-3.1.xsd /schema/context /schema/context/spring-context-3.1.xsd /schema/mvc /schema/mvc/spring-mvc-4.0.xsd"> <context:component-scan base-package=".hnust.controller"/><bean id="mappingJacksonHttpMessageConverter" class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter"><property name="supportedMediaTypes"><list><value>text/html;charset=UTF-8</value></list></property></bean><bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"><property name="messageConverters"><list><ref bean="mappingJacksonHttpMessageConverter"/></list></property></bean> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"><property name="prefix" value="/WEB-INF/jsp/"/><property name="suffix" value=".jsp"/></bean> <bean id="multipartResolver" class="org.springframework.monsMultipartResolver"><property name="defaultEncoding" value="utf-8"/><property name="maxUploadSize" value="10485760000"/><property name="maxInMemorySize" value="40960"/></bean><mvc:annotation-driven/></beans>

2）配置web.xml文件

<?xml version="1.0" encoding="UTF-8"?><web-app xmlns:xsi="/2001/XMLSchema-instance" xmlns="/xml/ns/javaee" xsi:schemaLocation="/xml/ns/javaee /xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0"><display-name>ssm</display-name><context-param><param-name>contextConfigLocation</param-name><param-value>classpath:spring-mybatis.xml</param-value></context-param><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><listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener><listener><listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class></listener><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><url-pattern>/</url-pattern></servlet-mapping><welcome-file-list><welcome-file>index.jsp</welcome-file></welcome-file-list></web-app>

9、新建jsp文件（WebContent->WEB-INF->jsp->showUser.jsp）

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <title>测试</title> </head> <body> ${user.userName} </body> </html>

10、建立UserController类

package .hnust.controller;import javax.annotation.Resource;import javax.servlet.http.HttpServletRequest;import org.springframework.stereotype.Controller;import org.springframework.ui.Model;import org.springframework.web.bind.annotation.RequestMapping;import .hnust.model.User;import .hnust.service.IUserService;@Controller@RequestMapping("/user")public class UserController {@Resourceprivate IUserService userService;@RequestMapping("/showUser")public String toIndex(HttpServletRequest request,Model model) {int userId=Integer.parseInt(request.getParameter("id"));User user=this.userService.getUserById(userId);model.addAttribute("user",user);return "showUser";}}

11、输入地址

浏览器输入：http://localhost:8080/ssm/user/showUser?id=1
