1.开发环境搭建以及创建Maven Web项目
参看之前的博文：http://www.cnblogs.com/cainiaomahua/p/6306476.html
2.SSM整合
这次整合有2个配置文件，分别是spring-mybatis.xml，包含spring和mybatis的配置文件，还有个是spring-mvc的配置文件，此外有2个资源文件：jdbc.propertis和log4j.properties。
完整目录结构如下:
使用框架的版本：
Spring 4.0.2 RELEASE
Spring MVC 4.0.2 RELEASE
MyBatis 3.2.6
2.1 Maven引入需要的JAR包
在pom.xml中引入jar包(此处引入jar包,可以复制代码,也可以使用视图的方式,参考此链接:http://www.360doc.com/content/14/0517/18/9560593_378558295.shtml)

2.2 整合SpringMVC
2.2.1 配置spring-mvc.xml
配置里面的注释也很详细，主要是自动扫描控制器，视图模式，注解的启动这三个。
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:p="http://www.springframework.org/schema/p" 4 xmlns:context="http://www.springframework.org/schema/context" 5 xmlns:mvc="http://www.springframework.org/schema/mvc" 6 xsi:schemaLocation=" 7 http://www.springframework.org/schema/beans 8 http://www.springframework.org/schema/beans/spring-beans-3.1.xsd 9 http://www.springframework.org/schema/context 10 http://www.springframework.org/schema/context/spring-context-3.1.xsd 11 http://www.springframework.org/schema/mvc 12 http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd"> 13 <!-- 自动扫描,使SpringMVC认为包下用了@Controller注解的类是控制器 --> 14 <context:component-scan base-package="com.cn.hnust.controller" /> 15 <!-- 扩充了注解驱动,可以将请求参数绑定到控制器参数 --> 16 <mvc:annotation-driven /> 17 <!-- 静态资源处理 css js imgs --> 18 <mvc:resources location="/resources/**" mapping="/resources" /> 19 <!-- 避免IE执行AJAX时,返回JSON出现下载文件 --> 20 <bean id="mappingJacksonHttpMessageConverter" 21 class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter"> 22 <property name="supportedMediaTypes"> 23 <list> 24 <value>text/html;charset=UTF-8</value> 25 </list> 26 </property> 27 </bean> 28 29 <!-- 启动SpringMVC的注解功能,完成请求和注解POJO的映射 --> 30 <bean 31 class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"> 32 <property name="messageConverters"> 33 <list> 34 <!-- JSON转换器 --> 35 <ref bean="mappingJacksonHttpMessageConverter" /> 36 </list> 37 </property> 38 </bean> 39 40 <!-- 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 --> 41 <bean id="multipartResolver" 42 class="org.springframework.web.multipart.commons.CommonsMultipartResolver"> 43 <!-- 默认编码 --> 44 <property name="defaultEncoding" value="utf-8"></property> 45 <!-- 文件大小最大值 --> 46 <property name="maxUploadSize" value="10485760000"></property> 47 <!-- 内存中的最大值 --> 48 <property name="maxInMemorySize" value="40960"></property> 49 <!-- 启用是为了推迟文件解析,以便捕获文件大小异常 --> 50 <property name="resolveLazily" value="true"></property> 51 </bean> 52 53 <!-- 配置ViewResolver。可用多个ViewResolver。使用order属性排序。 InternalResourceViewResolver 54 放在最后 --> 55 <bean 56 class="org.springframework.web.servlet.view.ContentNegotiatingViewResolver"> 57 <property name="order" value="1"></property> 58 <property name="mediaTypes"> 59 <map> 60 <!-- 告诉视图解析器,返回的类型是json格式 --> 61 <entry key="json" value="application/json"></entry> 62 <entry key="xml" value="application/xml"></entry> 63 <entry key="htm" value="text/htm"></entry> 64 </map> 65 </property> 66 <property name="defaultViews"> 67 <list> 68 <!-- ModelAndView里的数据变成JSON --> 69 <bean 70 class="org.springframework.web.servlet.view.json.MappingJacksonJsonView"></bean> 71 </list> 72 </property> 73 <property name="ignoreAcceptHeader" value="true"></property> 74 </bean> 75 <!-- 定义跳转的文件的前后缀,视图模式配置 --> 76 <bean 77 class="org.springframework.web.servlet.view.InternalResourceViewResolver"> 78 <!-- 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 --> 79 <property name="prefix" value="/WEB-INF/jsp/"></property> 80 <property name="suffix" value=".jsp"></property> 81 </bean> 82 </beans>
2.2.2 配置web.xml文件
配置的spring-mvc的Servlet就是为了完成SpringMVC+MAVEN的整合。
web.xml
1 <?xml version="1.0" encoding="UTF-8"?> 2 <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 3 xmlns="http://java.sun.com/xml/ns/javaee" 4 xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" 5 version="3.0"> 6 <display-name>Archetype Created Web Application</display-name> 7 <!-- Spring和MyBatis的配置文件 --> 8 <!-- <context-param> 9 <param-name>contextConfigLocation</param-name> 10 <param-value>classpath:spring-mybatis.xml</param-value> 11 </context-param> --> 12 <!-- 编码过滤器 --> 13 <filter> 14 <filter-name>encodingFilter</filter-name> 15 <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> 16 <async-supported>true</async-supported> 17 <init-param> 18 <param-name>encoding</param-name> 19 <param-value>UTF-8</param-value> 20 </init-param> 21 </filter> 22 <filter-mapping> 23 <filter-name>encodingFilter</filter-name> 24 <url-pattern>/*</url-pattern> 25 </filter-mapping> 26 <!-- Spring监听器 --> 27 <!-- <listener> 28 <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> 29 </listener> --> 30 <!-- 防止Spring内存溢出监听器 --> 31 <!-- <listener> 32 <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class> 33 </listener> --> 34 35 <!-- Spring MVC servlet --> 36 <servlet> 37 <servlet-name>SpringMVC</servlet-name> 38 <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> 39 <!-- 下面init-param是自定义servlet.xml配置文件的位置和名称，默认为WEB-INF目录下，名称为[<servlet-name>]-servlet.xml，如spring-servlet.xml --> 40 <init-param> 41 <param-name>contextConfigLocation</param-name> 42 <param-value>classpath:spring-mvc.xml</param-value> 43 </init-param> 44 <load-on-startup>1</load-on-startup> 45 <async-supported>true</async-supported> 46 </servlet> 47 <servlet-mapping> 48 <servlet-name>SpringMVC</servlet-name> 49 <!-- 此处可以配置成*.do,对应struts的后缀习惯 --> 50 <url-pattern>/</url-pattern> 51 </servlet-mapping> 52 <welcome-file-list> 53 <welcome-file>/index.jsp</welcome-file> 54 </welcome-file-list> 55 </web-app>
2.2.3 Log4j的配置
为了方便调试，一般都会使用日志来输出信息，Log4j是Apache的一个开放源代码项目，通过使用Log4j，我们可以控制日志信息输送的目的地是控制台、文件、GUI组件，甚至是套接口服务器、NT的事件记录器、UNIX Syslog守护进程等；我们也可以控制每一条日志的输出格式；通过定义每一条日志信息的级别，我们能够更加细致地控制日志的生成过程。
Log4j的配置很简单，而且也是通用的，下面给出一个基本的配置，换到其他项目中也无需做多大的调整。
log4j.properties
1 #定义LOG输出级别
2 log4j.rootLogger=INFO,Console,File
3 #定义日志输出目的地为控制台
4 log4j.appender.Console=org.apache.log4j.ConsoleAppender
5 log4j.appender.Console.Target=System.out
6 #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
7 log4j.appender.Console.layout=org.apache.log4j.PatternLayout
8 log4j.appender.Console.layout.ConversionPattern=[%c] - %m%n
9
10 #文件大小达到指定尺寸的时候产生一个新的文件
11 log4j.appender.File=org.apache.log4j.RollingFileAppender
12 #指定输出目录
13 log4j.appender.File.File=logs/ssm.log
14 #定义文件最大大小
15 log4j.appender.File.MaxFileSize=10MB
16 #输出所有日志,如果换成DEBUG表示输出DEBUG以上级别日志
17 log4j.appender.File.Threshold=ALL
18 log4j.appender.File.layout=org.apache.log4j.PatternLayout
19 log4j.appender.File.layout.ConversionPattern =[%p] [%d{yyyy-MM-dd HH:mm:ss}][%c]%m%n
2.2.4 使用Jetty测试
Student类对应于数据库中表的属性
1 package com.cn.hnust.pojo;
2
3 public class Student {
4 private Integer id;
5
6 private String stu_name;
7
8 private Integer gender;
9
10 private Integer age;
11
12 private String address;
13
14 public Integer getId() {
15 return id;
16 }
17
18 public void setId(Integer id) {
19 this.id = id;
20 }
21
22 public String getStu_name() {
23 return stu_name;
24 }
25
26 public void setStu_name(String stu_name) {
27 this.stu_name = stu_name;
28 }
29
30 public Integer getGender() {
31 return gender;
32 }
33
34 public void setGender(Integer gender) {
35 this.gender = gender;
36 }
37
38 public Integer getAge() {
39 return age;
40 }
41
42 public void setAge(Integer age) {
43 this.age = age;
44 }
45
46 public String getAddress() {
47 return address;
48 }
49
50 public void setAddress(String address) {
51 this.address = address;
52 }
53
54 @Override
55 public String toString() {
56 return "Student [id=" + id + ", stu_name=" + stu_name + ", gender="
57 + gender + ", age=" + age + ", address=" + address + "]";
58 }
59 }
控制器类
1 package com.cn.hnust.controller;
2
3 import java.io.File;
4 import java.io.IOException;
5 import java.util.Map;
6
7 import javax.annotation.Resource;
8 import javax.servlet.http.HttpServletRequest;
9
10 import org.apache.commons.io.FileUtils;
11 import org.slf4j.Logger;
12 import org.slf4j.LoggerFactory;
13 import org.springframework.http.HttpStatus;
14 import org.springframework.http.ResponseEntity;
15 import org.springframework.stereotype.Controller;
16 import org.springframework.ui.Model;
17 import org.springframework.web.bind.annotation.PathVariable;
18 import org.springframework.web.bind.annotation.RequestMapping;
19 import org.springframework.web.bind.annotation.RequestMethod;
20 import org.springframework.web.bind.annotation.RequestParam;
21 import org.springframework.web.bind.annotation.ResponseBody;
22 import org.springframework.web.multipart.MultipartFile;
23
24 import com.cn.hnust.pojo.Student;
25 import com.cn.hnust.service.IStudentService;
26
27 @Controller
28 @RequestMapping("/student")
29 public class StudentController {
30 private static Logger log = LoggerFactory
31 .getLogger(StudentController.class);
32
33 @Resource
34 private IStudentService studentService;
35
36 // /student/test?id=1
37 @RequestMapping(value = "/test", method = RequestMethod.GET)
38 public String test(HttpServletRequest request, Model model) {
39 int studentId = Integer.parseInt(request.getParameter("id"));
40 System.out.println("test studentId:" + studentId);
41 Student student = null;
42 if (studentId == 1) {
43 student = new Student();
44 student.setAge(19);
45 student.setId(1);
46 student.setGender(1);
47 student.setAddress("北京七里省际大厦3栋4402");
48 student.setStu_name("江泽");
49 }
50
51 log.debug(student.toString());
52 model.addAttribute("student", student);
53 return "index";
54 }
55 }
运行测试
控制台没有报错
在浏览器中输入：http://localhost:8090/student/test?id=1 (端口号根据你的设置有关,自己调查)
到此 SpringMVC+Maven 整合完毕
2.3 Spring与MyBatis的整合
取消2.2.2 web.xml中注释的代码,下面是去除后的代码
1 <?xml version="1.0" encoding="UTF-8"?> 2 <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 3 xmlns="http://java.sun.com/xml/ns/javaee" 4 xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" 5 version="3.0"> 6 <display-name>Archetype Created Web Application</display-name> 7 <!-- Spring和MyBatis的配置文件 --> 8 <context-param> 9 <param-name>contextConfigLocation</param-name> 10 <param-value>classpath:spring-mybatis.xml</param-value> 11 </context-param> 12 <!-- 编码过滤器 --> 13 <filter> 14 <filter-name>encodingFilter</filter-name> 15 <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> 16 <async-supported>true</async-supported> 17 <init-param> 18 <param-name>encoding</param-name> 19 <param-value>UTF-8</param-value> 20 </init-param> 21 </filter> 22 <filter-mapping> 23 <filter-name>encodingFilter</filter-name> 24 <url-pattern>/*</url-pattern> 25 </filter-mapping> 26 <!-- Spring监听器 --> 27 <listener> 28 <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> 29 </listener> 30 <!-- 防止Spring内存溢出监听器 --> 31 <listener> 32 <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class> 33 </listener> 34 35 <!-- Spring MVC servlet --> 36 <servlet> 37 <servlet-name>SpringMVC</servlet-name> 38 <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> 39 <!-- 下面init-param是自定义servlet.xml配置文件的位置和名称，默认为WEB-INF目录下，名称为[<servlet-name>]-servlet.xml，如spring-servlet.xml --> 40 <init-param> 41 <param-name>contextConfigLocation</param-name> 42 <param-value>classpath:spring-mvc.xml</param-value> 43 </init-param> 44 <load-on-startup>1</load-on-startup> 45 <async-supported>true</async-supported> 46 </servlet> 47 <servlet-mapping> 48 <servlet-name>SpringMVC</servlet-name> 49 <!-- 此处可以配置成*.do,对应struts的后缀习惯 --> 50 <url-pattern>/</url-pattern> 51 </servlet-mapping> 52 <welcome-file-list> 53 <welcome-file>/index.jsp</welcome-file> 54 </welcome-file-list> 55 </web-app>
2.3.1、建立JDBC属性文件
jdbc.properties（文件编码修改为utf-8） 根据自己数据库配置url username password
1 #连接数据库 2 #jdbc.driver=net.sf.log4jdbc.DriverSpy 3 #jdbc.url=jdbc:log4jdbc:oracle:thin:@192.168.0.125:1521:xe 4 jdbc.driver=oracle.jdbc.OracleDriver 5 jdbc.url=jdbc:oracle:thin:@192.168.0.125:1521:xe 6 jdbc.username=orcl 7 jdbc.password=orcl 8 9 #dbcp settings 10 dbcp.maxIdle=5 11 dbcp.maxActive=50
2.3.2、建立spring-mybatis.xml配置文件
这个文件就是用来完成spring和mybatis的整合的。主要的就是自动扫描，自动注入，配置数据库。注释也很详细，大家看看就明白了。
spring-mybatis.xml

2.4 JUnit测试
创建实体类、MyBatis映射文件以及DAO接口
DAO接口类
1 package com.cn.hnust.dao;

3 import com.cn.hnust.pojo.Student;
4
5 public interface IStudentDao {
6 int deleteByPrimaryKey(Integer id);
