2、整合SpringMVC：

（1）在web.xml文件中配置前端控制器：

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_2_5.xsd"

id="serviceMarket" version="2.5">

ssm-test

index.html

index.htm

index.jsp

default.html

default.htm

default.jsp

contextConfigLocation

classpath:spring/applicationContext*.xml

org.springframework.web.context.ContextLoaderListener

CharacterEncodingFilter

org.springframework.web.filter.CharacterEncodingFilter

encoding

utf-8

CharacterEncodingFilter

ssm-test

org.springframework.web.servlet.DispatcherServlet

contextConfigLocation

classpath:spring/springmvc.xml

ssm-test

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_2_5.xsd"

id="serviceMarket" version="2.5">

ssm-test

index.html

index.htm

index.jsp

default.html

default.htm

default.jsp

contextConfigLocation

classpath:spring/applicationContext*.xml

org.springframework.web.context.ContextLoaderListener

CharacterEncodingFilter

org.springframework.web.filter.CharacterEncodingFilter

encoding

utf-8

CharacterEncodingFilter

ssm-test

org.springframework.web.servlet.DispatcherServlet

contextConfigLocation

classpath:spring/springmvc.xml

ssm-test

（2）编写springmvc.xml文件：

在文件中配置与springmvc框架相关的配置，比如：springmvc.xml约束、处理器映射器、处理器适配器、视图解析器、Handler等配置。

xmlns:xsi="http://w3.org/2001/XMLSchema-instance" xmlns:p="http://springframework.org/schema/p"

xmlns:context="http://springframework.org/schema/context"

xmlns:mvc="http://springframework.org/schema/mvc"

xsi:schemaLocation="http://springframework.org/schema/beans http://springframework.org/schema/beans/spring-beans.xsd

http://springframework.org/schema/mvc http://springframework.org/schema/mvc/spring-mvc-4.0.xsd

http://springframework.org/schema/context http://springframework.org/schema/context/spring-context.xsd">

class="org.springframework.web.multipart.commons.CommonsMultipartResolver">

xmlns:xsi="http://w3.org/2001/XMLSchema-instance" xmlns:p="http://springframework.org/schema/p"

xmlns:context="http://springframework.org/schema/context"

xmlns:mvc="http://springframework.org/schema/mvc"

xsi:schemaLocation="http://springframework.org/schema/beans http://springframework.org/schema/beans/spring-beans.xsd

http://springframework.org/schema/mvc http://springframework.org/schema/mvc/spring-mvc-4.0.xsd

http://springframework.org/schema/context http://springframework.org/schema/context/spring-context.xsd">

class="org.springframework.web.multipart.commons.CommonsMultipartResolver">

（3）编写Handler：

//User类的Handler

//需要在类上面加@Controller注解，这样才能被自动扫描到

@Controller

@RequestMapping("/user")

public class UserController {

private static Logger log=LoggerFactory.getLogger(UserController.class);

@RequestMapping(value="/login",method=RequestMethod.GET)

public String login(HttpServletRequest request,Model model){

String username = request.getParameter("username");

String password = request.getParameter("password");

System.out.println("username:"+username+";password:"+password);

User user=null;

if (username.equals("zwp") && password.equals("123456")) {

user = new User();

user.setAge(11);

user.setId(1);

user.setPassword("123456");

user.setUsername("zwp");

log.debug(user.toString());

}

model.addAttribute("user", user);

return "index";

}

//User实体类

public class User {

private Integer id;

private String username;

private String password;

private Integer age;

public Integer getId() {

return id;

}

public void setId(Integer id) {

this.id = id;

}

public String getUsername() {

return uhttp://sername;

}

public void setUsername(String username) {

this.username = username;

}

public String getPassword() {

return password;

}

public void setPassword(String password) {

this.password = password;

}

public Integer getAge() {

return age;

}

public void setAge(Integer age) {

this.age = age;

}

@Override

public String toString() {

return "User [id=" + id + ", username=" + username + ", password=" + password + ", age=" + age + "]";

}

（4）配置日志文件：

在项目根目录下面创建log4j.properties日志文件，下面是日志文件的基本配置，可以满足大多数项目的需求。

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）启动项目，进行测试：

访问地址：http://localhost:8080/ssm/user/login?username=zwp&password=123456，如果出现下面页面则代表映射成功。

至此，SpringMVC的配置就已经成功。

3、Spring和Mybatis框架的整合：

整合思路：由Spring通过单例方式管理SqlSessionFactory；spring和mybatis整合生成代理对象，使用SqlSessionFactory创建SqlSession，持久层的mapper都需要有spring进行管理。

（1）配置dao层，即配置sqlSessionFactory：（我的配置在applicationContext-dao.xml文件中）

xmlns:context="http://springframework.org/schema/context" xmlns:p="http://springframework.org/schema/p"

xmlns:aop="http://springframework.org/schema/aop" xmlns:tx="http://springframework.org/schema/tx"

xmlns:xsi="http://w3.org/2001/XMLSchema-instance"

xsi:schemaLocation="http://springframework.org/schema/beans http://springframework.org/schema/beans/spring-beans-4.0.xsd

http://springframework.org/schema/context http://springframework.org/schema/context/spring-context-4.0.xsd

http://springframework.org/schema/aop http://springframework.org/schema/aop/spring-aop-4.0.xsd http://springframework.org/schema/tx http://springframework.org/schema/tx/spring-tx-4.0.xsd

http://springframework.org/schema/util http://springframework.org/schema/util/spring-util-4.0.xsd">

destroy-method="close">

xmlns:context="http://springframework.org/schema/context" xmlns:p="http://springframework.org/schema/p"

xmlns:aop="http://springframework.org/schema/aop" xmlns:tx="http://springframework.org/schema/tx"

xmlns:xsi="http://w3.org/2001/XMLSchema-instance"

xsi:schemaLocation="http://springframework.org/schema/beans http://springframework.org/schema/beans/spring-beans-4.0.xsd

http://springframework.org/schema/context http://springframework.org/schema/context/spring-context-4.0.xsd

http://springframework.org/schema/aop http://springframework.org/schema/aop/spring-aop-4.0.xsd http://springframework.org/schema/tx http://springframework.org/schema/tx/spring-tx-4.0.xsd

http://springframework.org/schema/util http://springframework.org/schema/util/spring-util-4.0.xsd">

destroy-method="close">

创建并编写SqlMapConfig.xml文件：

PUBLIC "-//mybatis.org//DTD Config 3.0//EN"

"http://mybatis.org/dtd/mybatis-3-config.dtd">

（2）配置service层：（我的配置在applicationContext-service.xml文件中）

xmlns:context="http://springframework.org/schema/context" xmlns:p="http://springframework.org/schema/p"

xmlns:aop="http://springframework.org/schema/aop" xmlns:tx="http://springframework.org/schema/tx"

xmlns:xsi="http://w3.org/2001/XMLSchema-instance"

xsi:schemaLocation="http://springframework.org/schema/beans http://springframework.org/schema/beans/spring-beans-4.0.xsd

http://springframework.org/schema/context http://springframework.org/schema/context/spring-context-4.0.xsd

http://springframework.org/schema/aop http://springframework.org/schema/aop/spring-aop-4.0.xsd http://springframework.org/schema/tx http://springframework.org/schema/tx/spring-tx-4.0.xsd

http://springframework.org/schema/util http://springframework.org/schema/util/spring-util-4.0.xsd">

xmlns:context="http://springframework.org/schema/context" xmlns:p="http://springframework.org/schema/p"

xmlns:aop="http://springframework.org/schema/aop" xmlns:tx="http://springframework.org/schema/tx"

xmlns:xsi="http://w3.org/2001/XMLSchema-instance"

xsi:schemaLocation="http://springframework.org/schema/beans http://springframework.org/schema/beans/spring-beans-4.0.xsd

http://springframework.org/schema/context http://springframework.org/schema/context/spring-context-4.0.xsd

http://springframework.org/schema/aop http://springframework.org/schema/aop/spring-aop-4.0.xsd http://springframework.org/schema/tx http://springframework.org/schema/tx/spring-tx-4.0.xsd

http://springframework.org/schema/util http://springframework.org/schema/util/spring-util-4.0.xsd">

（3）配置事务：（我的配置在applicationContext-trans.xml文件中）

xmlns:context="http://springframework.org/schema/context" xmlns:p="http://springframework.org/schema/p"

xmlns:aop="http://springframework.org/schema/aop" xmlns:tx="http://springframework.org/schema/tx"

xmlns:xsi="http://w3.org/2001/XMLSchema-instance"

xsi:schemaLocation="http://springframework.org/schema/beans http://springframework.org/schema/beans/spring-beans-4.0.xsd

http://springframework.org/schema/context http://springframework.org/schema/context/spring-context-4.0.xsd

http://springframework.org/schema/aop http://springframework.org/schema/aop/spring-aop-4.0.xsd http://springframework.org/schema/tx http://springframework.org/schema/tx/spring-tx-4.0.xsd

http://springframework.org/schema/util http://springframework.org/schema/util/spring-util-4.0.xsd">

class="org.springframework.jdbc.datasource.DataSourceTransactionManager">

pointcut="execution(* com.zwp.service.*.*(..))" />

xmlns:context="http://springframework.org/schema/context" xmlns:p="http://springframework.org/schema/p"

xmlns:aop="http://springframework.org/schema/aop" xmlns:tx="http://springframework.org/schema/tx"

xmlns:xsi="http://w3.org/2001/XMLSchema-instance"

xsi:schemaLocation="http://springframework.org/schema/beans http://springframework.org/schema/beans/spring-beans-4.0.xsd

http://springframework.org/schema/context http://springframework.org/schema/context/spring-context-4.0.xsd

http://springframework.org/schema/aop http://springframework.org/schema/aop/spring-aop-4.0.xsd http://springframework.org/schema/tx http://springframework.org/schema/tx/spring-tx-4.0.xsd

http://springframework.org/schema/util http://springframework.org/schema/util/spring-util-4.0.xsd">

class="org.springframework.jdbc.datasource.DataSourceTransactionManager">

pointcut="execution(* com.zwp.service.*.*(..))" />

至此，Spring和Mybatis框架的整合就完成了。

4、测试：

（1）创建测试用表：

（2）利用MyBatis-Generator自动创建实体类、Mybatis映射文件以及Dao接口。

（3）建立Service和实现类：

//UserService接口类：

@Service

public interface UserService {

public User getUserById(int userId);

}

//UserService的实现类

@Service

public class UserServiceImpl implements UserService {

//注入UserMapper接口

@Autowired

private UserMapper userMapper;

@Override

public User getUserById(int userId) {

User user = userMapper.selectByPrimaryKey(userId);

return user;

}

（3）建立UserController类：

//User类的Handler

//需要在类上面加@Controller注解，这样才能被自动扫描到

@Controller

@RequestMapping("/user")

public class UserController {

@Autowired

private UserService userService;

private static Logger log=LoggerFactory.getLogger(UserController.class);

@RequestMapping(value="/getUserById/{userId}",method=RequestMethod.GET)

public @ResponseBody User getUserById(@PathVariable Integer userId){

return userService.getUserById(userId);

}

@RequestMapping(value="/login",method=RequestMethod.GET)

public String login(HttpServletRequest request,Model model){

String username = request.getParameter("username");

String password = request.getParameter("password");

System.out.println("username:"+username+";password:"+password);

User user=null;

if (username.equals("zwp") && password.equals("123456")) {

user = new User();

user.setAge(11);

user.setId(1);

user.setPassword("123456");

user.setUsername("zwp");

log.debug(user.toString());

}

model.addAttribute("user", user);

return "index";

}

（4）部署项目，输入地址：http://localhost:8080/ssm/user/getUserById/2，出现下面响应结果，则表示整合成功了。

至此，Maven+Spring+SpringMVC+Mybatis的整合就完成了。
