Maven+Spring+SpringMVC+MyBatis+MySQL 整合SSM框架

一、Mysql数据库 （书表，种类表 多对多的关系）

CREATE TABLE `book` (  `bid` int(11) NOT NULL AUTO_INCREMENT,  `bname` varchar(20) DEFAULT NULL,  PRIMARY KEY (`bid`)) ENGINE=MyISAM AUTO_INCREMENT=11 DEFAULT CHARSET=utf8;-- ------------------------------ Records of book-- ----------------------------INSERT INTO `book` VALUES ('1', 'SQL技术');INSERT INTO `book` VALUES ('2', 'SSM+MySQL详解');INSERT INTO `book` VALUES ('3', 'C++和java对比');-- ------------------------------ Table structure for category-- ----------------------------DROP TABLE IF EXISTS `category`;CREATE TABLE `category` (  `cid` int(11) NOT NULL AUTO_INCREMENT,  `cname` varchar(20) DEFAULT NULL,  PRIMARY KEY (`cid`)) ENGINE=MyISAM AUTO_INCREMENT=4 DEFAULT CHARSET=utf8;-- ------------------------------ Records of category-- ----------------------------INSERT INTO `category` VALUES ('1', 'java');INSERT INTO `category` VALUES ('2', 'c++');INSERT INTO `category` VALUES ('3', 'mysql');-- ------------------------------ Table structure for middle-- ----------------------------DROP TABLE IF EXISTS `middle`;CREATE TABLE `middle` (  `m_bid` int(11) DEFAULT NULL,  `m_cid` int(11) DEFAULT NULL,  KEY `fk_bid` (`m_bid`),  KEY `fk_cid` (`m_cid`)) ENGINE=MyISAM DEFAULT CHARSET=utf8;-- ------------------------------ Records of middle-- ----------------------------INSERT INTO `middle` VALUES ('1', '3');INSERT INTO `middle` VALUES ('2', '1');INSERT INTO `middle` VALUES ('2', '3');INSERT INTO `middle` VALUES ('3', '2');INSERT INTO `middle` VALUES ('3', '1');

二、Maven WEB项目的创建（省略）

   2.1）pom.xml文件 

<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/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><groupId>ssmaven</groupId><artifactId>ssmaven</artifactId><version>0.0.1-SNAPSHOT</version><packaging>war</packaging><name /><description /><properties><project.build.sourceEncoding>UTF-8</project.build.sourceEncoding></properties><dependencies><!-- https://mvnrepository.com/artifact/org.mybatis/mybatis --><dependency><groupId>org.mybatis</groupId><artifactId>mybatis</artifactId><version>3.2.3</version></dependency><!-- https://mvnrepository.com/artifact/org.mybatis/mybatis-spring --><dependency><groupId>org.mybatis</groupId><artifactId>mybatis-spring</artifactId><version>1.2.3</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-webmvc</artifactId><version>4.3.10.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-tx</artifactId><version>4.3.10.RELEASE</version></dependency><!-- https://mvnrepository.com/artifact/org.springframework/spring-jdbc --><dependency><groupId>org.springframework</groupId><artifactId>spring-jdbc</artifactId><version>4.3.10.RELEASE</version></dependency><!--mysql数据 --><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><version>5.1.22</version></dependency><!-- https://mvnrepository.com/artifact/junit/junit --><dependency><groupId>junit</groupId><artifactId>junit</artifactId><version>4.11</version><scope>test</scope> <!-- web发布时，这个包不用的！ --></dependency><!-- 阿里巴巴的數據源 --><dependency><groupId>com.alibaba</groupId><artifactId>druid</artifactId><version>1.0.29</version></dependency><!-- 显示日志信息 --><dependency><groupId>log4j</groupId><artifactId>log4j</artifactId><version>1.2.17</version></dependency><!-- spring test --><dependency><groupId>org.springframework</groupId><artifactId>spring-test</artifactId><version>3.0.5.RELEASE</version></dependency><!--织入的包 --><dependency><groupId>org.aspectj</groupId><artifactId>aspectjweaver</artifactId><version>1.8.6</version></dependency><!-- 阿里巴巴的JSON --><dependency><groupId>com.alibaba</groupId><artifactId>fastjson</artifactId><version>1.2.38</version></dependency><!--jsp标准标签库jstl --><dependency><groupId>jstl</groupId><artifactId>jstl</artifactId><version>1.2</version></dependency></dependencies><build><plugins><plugin><artifactId>maven-war-plugin</artifactId></plugin><plugin><artifactId>maven-compiler-plugin</artifactId><configuration><source>1.6</source><target>1.6</target></configuration></plugin></plugins></build></project>

 2.2）工程图：

  

三、用mybatis工具生成对应的dao,entity,mapping。

四、写Service层，接口和实现的类。

五、写配置文件

   5.1） config.properties

  

driverClassName=com.mysql.jdbc.DrivervalidationQuery=SELECT 1jdbc_url=jdbc:mysql://localhost:3306/school?useUnicode=true&characterEncoding=UTF-8&zeroDateTimeBehavior=convertToNulljdbc_username=rootjdbc_password=root

  5.2）log4j.properties

log4j.rootLogger=DEBUG,Console,Filelog4j.appender.Console=org.apache.log4j.ConsoleAppenderlog4j.appender.Console.Target=System.outlog4j.appender.Console.layout=org.apache.log4j.PatternLayoutlog4j.appender.Console.layout.ConversionPattern=[%c]%m%nlog4j.appender.File=org.apache.log4j.RollingFileAppender log4j.appender.File.File=mybatis.loglog4j.appender.File.MaxFileSize=10MBlog4j.appender.File.Threshold=ALLlog4j.appender.File.layout=org.apache.log4j.PatternLayoutlog4j.appender.File.layout.ConversionPattern=[%p][%d{yyyy-MM-dd HH\:mm\:ss,SSS}][%c]%m%n

  5.4）spring-service.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"xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsdhttp://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd"><!-- 自动扫描 --><context:component-scan base-package="com.hlx.service.impl" /></beans>

  5.5）springmvc.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-3.0.xsdhttp://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsdhttp://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd"><context:component-scan base-package="com.hlx.control" /><mvc:annotation-driven /><!-- 视图解析器 --><beanclass="org.springframework.web.servlet.view.InternalResourceViewResolver"><property name="prefix" value="/" /><property name="suffix" value=".jsp" /></bean></beans>

5.6）BookMapper.xml

<!-- 自己写 --><select id="getAll" resultMap="BaseResultMap">select * from book</select><!-- manytomany  第二种方式; extends继承哦！ --><resultMap type="com.hlx.entity.Book" id="BooKMapper"extends="BaseResultMap"><!-- property属性集合，column列FK； select查询 --><collection property="categories" column="m_cid" select="getCategory" /></resultMap><select id="getCategory" resultType="com.hlx.entity.Category">select * from category wherecid=#{cid}</select><!-- 根据ID查询数据 --><select id="findById" parameterType="int" resultMap="BooKMapper">select *from book b,middle m where b.bid=m.m_bid and b.bid=#{cid}</select><!-- manytomany 第一种方式; 查询全部数据(3张表的数据) --><resultMap type="com.hlx.entity.Book" id="BookMapper2"extends="BaseResultMap"><collection property="categories"ofType="com.hlx.entity.Category"><id column="cid" property="cid" jdbcType="INTEGER" /><result column="cname" property="cname" jdbcType="VARCHAR" /></collection></resultMap><select id="findById2" resultMap="BookMapper2">select * from book b,Middlem,category c where b.bid=m.m_bid andm.m_cid=c.cid</select>

六、测试

 

package com.hlx.test;import java.util.List;import org.apache.log4j.Logger;import org.junit.Test;import org.junit.runner.RunWith;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.test.context.ContextConfiguration;import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;import com.alibaba.fastjson.JSON;import com.hlx.entity.Book;import com.hlx.service.BookService;//spring单元测试@RunWith(SpringJUnit4ClassRunner.class)// 读取配置文件@ContextConfiguration(locations = { "classpath:spring-service.xml","classpath:spring-mybatis.xml" })public class TestBook {//日志对象private static Logger logger= Logger.getLogger(TestBook.class);@Autowiredprivate BookService bookService;@Testpublic void test1() throws Exception {Book book = bookService.getBookByID(1);//System.out.println(book);//此时输出的是[com.hlx.test.TestBook]com.hlx.entity.Book@1798928//具体的对象//logger.info(book);//将Object=>String类型logger.info(JSON.toJSONString(book));}@Testpublic void test2() throws Exception {List<Book> books = bookService.loadAll();//将Object=>String类型logger.info(JSON.toJSONStringWithDateFormat(books, null));}@Testpublic void testManytoMany() throws Exception {List<Book> books = bookService.findById(3);//将Object=>String类型logger.info(JSON.toJSONStringWithDateFormat(books, null));}}

七、Controller控制层

@Controllerpublic class BookController {@Autowiredprivate BookService bookService;@RequestMapping("/all")public String all(ModelMap map) throws Exception {List<Book> list = bookService.loadAll();map.put("list", list);return "index";}@RequestMapping("/many")public String many(ModelMap map,Integer cid) throws Exception {List<Book> list = bookService.findById(cid);map.put("list", list);return "show";}}

八、Web页面

   

  8.1) web.xml

   

<?xml version="1.0" encoding="UTF-8"?><web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"><display-name></display-name><welcome-file-list><welcome-file>index.jsp</welcome-file></welcome-file-list><!--配置全局参数 --> <context-param>        <param-name>contextConfigLocation</param-name>        <param-value>classpath:spring-*.xml</param-value>    </context-param><!--1) 启动Spring容器 --><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><!-- 2) 中文过滤器 --><filter><filter-name>ChinaFilter</filter-name><filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class><init-param><param-name>encoding</param-name><param-value>utf-8</param-value></init-param></filter><filter-mapping><filter-name>ChinaFilter</filter-name><url-pattern>/*</url-pattern></filter-mapping><!--3) springmvc前端控制器 --><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.xml</param-value></init-param><load-on-startup>1</load-on-startup></servlet><servlet-mapping><servlet-name>springMvc</servlet-name><url-pattern>*.action</url-pattern></servlet-mapping></web-app>

 8.2) index.jsp 

  

<table border="1" width="40%"><tr><td>bid</td><td>bname</td><td>select-kind</td></tr><c:forEach var="book" items="${list}"><tr><td>${book.bid }</td><td>${book.bname}</td><td><a href="many.action?cid=${book.bid }">kind</a></td></tr></c:forEach></table>

  8.3) show.jsp 

<table border="1" width="40%"><tr><td>bid</td><td>bname</td><td>cname</td></tr><c:forEach var="book" items="${list}"><tr><td>${book.bid }</td><td>${book.bname}</td> <!-- 书的种类 --><c:forEach var="c" items="${book.categories}"> <td>${c.cname}</td></c:forEach></tr></c:forEach></table>

运行结果：
