使用maven整合Spring+SpringMVC+Mybatis框架详细步骤(图文)
(项目结构图参照文章末尾)
1、创建maven工程,在pom.xml文件中导入需要的jar包依赖:
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">
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">
(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">
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">
destroy-method="close">
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">
class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
pointcut="execution(* com.zwp.service.*.*(..))" />
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。
