首先介绍一下，我的工具使用的是STS, 需要的童鞋可以到官网下载：http://spring.io/tools/sts/all
使用STS是因为她集成了Maven进行 “包“ 管理以及自带 Web server 方便部署（不用配置啦~），个人感觉还是挺方便的。如果大家想要自己配置Tomcat，也未尝不可 :)
我下载的是压缩包的STS，下载完成后解压缩 -> 启动STS.exe ->指定 workspace ->创建Maven项目 -> 选择建立 webapp 项目。 等待片刻以后，我们就可以看到STS为我们创建的项目架构如下：
在这里，我们使用Maven来做 jar 包的管理（修改 Maven 的 POM 文件即可）。
这里推荐一下 Maven 仓库的网址：http://mvnrepository.com 或者 http://search.maven.org
我们只需要在上面搜索需要的jar包，将<dependency />的内容复制到POM文件中的
<dependencies>
...
</dependencies>
即可完成Jar包的引用。
我这里参照的是Spring3.x版本，比较老，希望有更新版本的童鞋给我指点一下，THX~~
POM 内容如下，这里直接贴出所有依赖包：

这部分很简单，我在这里放出SQL与截图，供大家参考。
我们可以看到我们建立了一个数据库 db_SSM, 一张表t_user, 里面有两个user，具体的SQL如下：
/* SQLyog 企业版 - MySQL GUI v8.14 MySQL - 5.1.49-community : Database - db_ssm ********************************************************************* */ /*!40101 SET NAMES utf8 */; /*!40101 SET SQL_MODE=‘‘*/; /*!40014 SET @OLD_UNIQUE_CHECKS=@@UNIQUE_CHECKS, UNIQUE_CHECKS=0 */; /*!40014 SET @OLD_FOREIGN_KEY_CHECKS=@@FOREIGN_KEY_CHECKS, FOREIGN_KEY_CHECKS=0 */; /*!40101 SET @OLD_SQL_MODE=@@SQL_MODE, SQL_MODE=‘NO_AUTO_VALUE_ON_ZERO‘ */; /*!40111 SET @OLD_SQL_NOTES=@@SQL_NOTES, SQL_NOTES=0 */; CREATE DATABASE /*!32312 IF NOT EXISTS*/`db_ssm` /*!40100 DEFAULT CHARACTER SET utf8 */; USE `db_ssm`; /*Table structure for table `t_user` */ DROP TABLE IF EXISTS `t_user`; CREATE TABLE `t_user` ( `ID` int(11) NOT NULL AUTO_INCREMENT, `NAME` varchar(50) DEFAULT NULL, `PWD` varchar(50) DEFAULT NULL, PRIMARY KEY (`ID`) ) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=utf8; /*Data for the table `t_user` */ insert into `t_user`(`ID`,`NAME`,`PWD`) values (1,‘tony‘,‘tony‘),(2,‘sasha‘,‘sasha‘); /*!40101 SET SQL_MODE=@OLD_SQL_MODE */; /*!40014 SET FOREIGN_KEY_CHECKS=@OLD_FOREIGN_KEY_CHECKS */; /*!40014 SET UNIQUE_CHECKS=@OLD_UNIQUE_CHECKS */; /*!40111 SET SQL_NOTES=@OLD_SQL_NOTES */;
总的项目结构如下：
package cgt.service; import cgt.model.User; public interface IUserService { public User getUserById(int id); }
package cgt.service; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service; import cgt.dao.UserMapper; import cgt.model.User; @Service("userService") public class UserService implements IUserService{ private UserMapper userMapper; public UserMapper getUserMapper() { return userMapper; } @Autowired public void setUserMapper(UserMapper userMapper) { this.userMapper = userMapper; } public User getUserById(int id) { // TODO Auto-generated method stub User u=userMapper.selectById(id); return u; } }
由于我们以 Spring 自动扫描包的方式加载service，所以，在这里我们只要使用@service以及@autowired注解即可。
package cgt.dao; import cgt.model.User; public interface UserMapper { User selectById(int id); }
<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd" > <mapper namespace="cgt.dao.UserMapper"> <resultMap id="BaseResultMap" type="cgt.model.User"> <id column="ID" property="id" jdbcType="INTEGER" /> <result column="NAME" property="name" jdbcType="VARCHAR" /> <result column="PWD" property="pwd" jdbcType="VARCHAR" /> </resultMap> <sql id="Base_Column_List"> ID, NAME, PWD </sql> <select id="selectById" resultMap="BaseResultMap" parameterType="java.lang.Integer"> select <include refid="Base_Column_List" /> from t_user where ID = #{id,jdbcType=VARCHAR} </select> </mapper>
package cgt.model; public class User { private int id; private String name; private String pwd; public int getId() { return id; } public void setId(int id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } public String getPwd() { return pwd; } public void setPwd(String pwd) { this.pwd = pwd; } public User() { super(); // TODO Auto-generated constructor stub } public User(String name, String pwd) { super(); this.name = name; this.pwd = pwd; } @Override public String toString() { return "User [id=" + id + ", name=" + name + ", pwd=" + pwd + "]"; } }
到这里，我们关于Spring & Mybatis 相关的业务逻辑部分就完成了。
关于Junit test，这里介绍两种方式 ：
package cgt.test; import org.junit.Test; import org.springframework.context.ApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext; import cgt.model.User; import cgt.service.IUserService; public class SpinrgMybatisTest { @Test public void test1(){ ApplicationContext ac = new ClassPathXmlApplicationContext("classpath:spring-mybatis.xml"); IUserService userService=(IUserService)ac.getBean("userService"); User u = userService.getUserById(2); System.out.println(u); } }
测试结果：
首先需要在POM.xml引入jar包
<dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> <version>3.2.0.RELEASE</version> </dependency>
Test类的写法如下：
package cgt.test; import org.junit.Test; import org.junit.runner.RunWith; import org.springframework.beans.factory.annotation.Autowired; 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 cgt.model.User; import cgt.service.IUserService; @RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration(locations={"classpath:spring-mybatis.xml"}) public class SpinrgMybatisTest2 { private IUserService userService; public IUserService getUserService() { return userService; } @Autowired public void setUserService(IUserService userService) { this.userService = userService; } @Test public void test2(){ User u = userService.getUserById(1); System.out.println(u); } }
测试结果：
通过 Junit 测试，我们可以看到Spring & Mybatis 的集成成功啦， nice！ :)
我们需要以SpringMVC的方式接受HTTP Request，request的URL格式我们使用的是类似于REST的格式。例如：http://localhost:8080/SpringMVC_Mybatis/userController/getUserName.do?id=1
她是整个程序的入口，我们需要在这里特别注意两点：
1. 以SpringMVC的方式接受request（servlet）
2. 项目需要读取哪些配置文件。
<?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" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0"> <display-name>SpringMVC_Mybatis</display-name> <!-- 需要加载的配置文件 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring-mybatis.xml</param-value> </context-param> <!-- 字符集过滤器 --> <filter> <filter-name>encodingFilter</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>encodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <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> </servlet> <servlet-mapping> <servlet-name>springMvc</servlet-name> <url-pattern>*.do</url-pattern> </servlet-mapping> <!-- 配置session超时时间，单位分钟 --> <session-config> <session-timeout>15</session-timeout> </session-config> <welcome-file-list> <welcome-file>/index.jsp</welcome-file> </welcome-file-list> </web-app>
这里主要是 “指明” 扫描 Controller 的包下的类（与 @controller 配合）。
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:mvc="http://www.springframework.org/schema/mvc" 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.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd"> <!-- 自动扫描controller包下的所有类，使其认为spring mvc的控制器 --> <context:component-scan base-package="cgt.controller" /> <!-- 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Spring MVC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> <!-- 对模型视图名称的解析，即在模型视图名称添加前后缀 --> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" p:prefix="/" p:suffix=".jsp" /> <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"> <property name="defaultEncoding"> <value>UTF-8</value> </property> <property name="maxUploadSize"> <value>32505856</value><!-- 上传文件大小限制为31M，31*1024*1024 --> </property> <property name="maxInMemorySize"> <value>4096</value> </property> </bean> </beans>
这个类需要接受Request请求，并且转到对应的 JSP 页面
package cgt.controller; import javax.servlet.http.HttpServletRequest; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.PathVariable; import org.springframework.web.bind.annotation.RequestMapping; import cgt.service.IUserService; @Controller @RequestMapping("/userController") public class UserController { private IUserService userService; public IUserService getUserService() { return userService; } @Autowired public void setUserService(IUserService userService) { this.userService = userService; } @RequestMapping("/getUserName/{id}") public String getUserNameById(@PathVariable String id, HttpServletRequest request) { request.setAttribute("user", userService.getUserById(Integer.parseInt(id))); return "showUser"; } }
请注意这里的几个细节：
首先注解部分：
@Controller - 指明这是一个Controller类，需要被Spring管理。
@RequestMapping - 指明URL的请求路径。
@PathVariable - 与方法上面的@RequestMapping注解 中的 {id} 相结合，表示接受id作为请求的参数
方法的返回值：
返回值为 “showUser”。它与SpringMVC中的 “InternalResourceViewResolver”
<!-- 对模型视图名称的解析，即在模型视图名称添加前后缀 --> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" p:prefix="/" p:suffix=".jsp" />
一同指定了返回的jsp页面为： 根目录下的showUser.jsp，如图所示：
1. Maven install
2. 使用STS内置的Server，运行起来后输入URL=http://localhost:8080/SpringMVC_Mybatis/userController/getUserName/2.do
结果如下：
Well done！ 我们的集成之路顺利完成！！
lz入Java坑时间不长，所以我这里主要是参考网上的一些示例来做的集成。 因此，使用的Spring版本比较老，如果大家较新版本（Sping 4 or later）的集成，请务必推荐给我，感谢 :)
