SSM(SpringMVC Spring Mybatis)框架整合搭建

1、新建一个web工程。

2、首先看一下整体的框架结构：

3、将ssm框架搭建所需要的jar包复制到lib目录下

3、需要配置各个配置文件。

1）配置web.xml文件：

<?xml version="1.0" encoding="UTF-8"?>
<web-app
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance
http://www.springmodules.org/schema/cache/springmodules-cache.xsd
http://www.springmodules.org/schema/cache/springmodules-encache.xsd"
xmlns="http://java.sun.com/xml/ns/javaee"
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>qzone</display-name>
<welcome-file-list>
<welcome-file>user.jsp</welcome-file>
</welcome-file-list>
<!-- spring配置文件 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring/applicationContext.xml</param-value>
</context-param>
<!-- spring监听器 -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

<!-- 编码过滤器 -->
<filter>
<filter-name>encodingFilter</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<async-supported>true</async-supported>
<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>

<!-- 添加springmvc的支持 -->
<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/spring-mvc.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
<async-supported>true</async-supported>
</servlet>
<servlet-mapping>
<servlet-name>springMVC</servlet-name>
<url-pattern>*.do</url-pattern>
</servlet-mapping>
</web-app>

2）在resource/spring下创建applicationContext.xml配置文件：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

            <tx:method name="*" propagation="REQUIRED" read-only="true" />
        </tx:attributes>
    </tx:advice>
    
</beans>

3)在resource/spring下创建spring-mvc.xml文件：

<?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:aop="http://www.springframework.org/schema/aop" xmlns:context="http://www.springframework.org/schema/context"
    xmlns:jee="http://www.springframework.org/schema/jee" xmlns:tx="http://www.springframework.org/schema/tx"
    xmlns:mvc="http://www.springframework.org/schema/mvc"
    xsi:schemaLocation="
    http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd

    http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.1.xsd">
    <!-- 指定注解要扫描的包 -->
    <context:component-scan base-package="com.ekingwin.bas.cloud.user.web"></context:component-scan>
    <!-- 视图解析器，自动加上前缀和后缀 -->
    <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/"></property>
        <property name="suffix" value=".jsp"></property>
    </bean>
    

    <!-- Spring 来扫描指定包下的类，并注册被@Component，@Controller，@Service，@Repository等注解标记的组件 -->
    <mvc:annotation-driven />
 
</beans>

4）在resource/mybatis下创建mybatis-config.xml配置文件：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration 
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
    <!-- 批量定义别名，使得com.etc.entity包下的所有bean都使用别名（别名就是类名，首字母大写或小写都可以） -->
    <typeAliases>
        <package name="com.ekingwin.bas.cloud"/>
    </typeAliases>
</configuration>

5）在resource下创建dbconfig.properties文件：

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/ssm
jdbc.username=root
jdbc.password=123456

6）在resource下创建log4j.properties文件：

<span style="font-size:18px;">log4j.rootLogger=info,appender1,appender2
log4j.appender.appender1=org.apache.log4j.ConsoleAppender

log4j.appender.appender2.File=D:/logFile.txt
log4j.appender.appender1.layout=org.apache.log4j.TTCCLayout
log4j.appender.appender2.layout=org.apache.log4j.TTCCLayout</span>

7）在resource/mapper下创建UserMapper.xml文件：

<?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="com.ekingwin.bas.cloud.user.dao.IUserDao">
<!-- <resultMap type="User" id="UserResult">
        <result property="id" column="id"/>
        <result property="username" column="username"/>
    <result property="password" column="password"/> 
    </resultMap>      -->
<!--      <select id="login" parameterType="User" resultMap="UserResult">
        select * from user where username=#{username}
    </select> -->
   <select id="getInfo" parameterType="String" resultType="map">
        select * from user where username=#{username}
    </select> 
</mapper>

8）在user/web下的到下创建UserController.java文件：

package com.ekingwin.bas.cloud.user.web;
 
import javax.annotation.Resource;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;

import com.ekingwin.bas.cloud.user.UserException;
import com.ekingwin.bas.cloud.user.dao.entity.User;
import com.ekingwin.bas.cloud.user.dto.UserDto;
import com.ekingwin.bas.cloud.user.service.IUserService;
import com.ekingwin.bas.cloud.user.service.impl.UserServiceImpl;




//@RestController
@Controller
@RequestMapping("/user")
public class UserController {

    @Autowired
//    @Qualifier(value = "userMetaServiceImpl")
    private IUserService userService;
    
//    
//    @Resource
//    private UserServiceImpl userService;
    
//    @RequestMapping(value = "/login", method = RequestMethod.POST)
//    public String login(UserDto user) throws UserException{
//        System.out.println("123123");
//        return     userService.getmessage(user);
//        }
    
    @RequestMapping(value = "/login", method = RequestMethod.POST)
    public String login (@RequestBody UserDto user) throws UserException{
        System.out.println("123123");
        return     userService.getmessage(user);
//        User resultUser = userService.login(user);
//        if(resultUser == null){
//            request.setAttribute("user", user);
//            request.setAttribute("errorMsg","用户名或密码错误");
//            return "index";
//        }else{
//            HttpSession session = request.getSession();
//            session.setAttribute("currentUser",user);
//            return "redirect:/success.jsp";
//        }
//        return  null;
    }
    
}

9）在user/service下创建IUserService.java：

package com.ekingwin.bas.cloud.user.service;

import javax.servlet.http.HttpServletRequest;

import com.ekingwin.bas.cloud.user.UserException;
import com.ekingwin.bas.cloud.user.dto.UserDto;

public interface IUserService {
    
    public String  getmessage(UserDto user) throws UserException;

}

10）在user/service/impl下创建UserServiceImpl.java文件：

package com.ekingwin.bas.cloud.user.service.impl;

import java.util.List;
import java.util.Map;

import javax.annotation.Resource;
import javax.servlet.http.HttpServletRequest;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Primary;
import org.springframework.stereotype.Service;

import com.ekingwin.bas.cloud.user.UserException;

import com.ekingwin.bas.cloud.user.dao.IUserDao;
import com.ekingwin.bas.cloud.user.dao.entity.User;
import com.ekingwin.bas.cloud.user.dto.UserDto;
import com.ekingwin.bas.cloud.user.service.IUserService;


@Primary
@Service
public class UserServiceImpl implements IUserService{
    
//    @Resource
//    private UserDao userDao;
    
    @Autowired
    private IUserDao userDao;

    public User login(User user) {
        User users =  userDao.login(user);
        System.out.println("12313247092137498123");
         return users;
    }
    
    @Override
    public String getmessage(UserDto user) throws UserException {
        // TODO Auto-generated method stub
        
        String username = user.getUsername();
        List<Map<String, Object>>  list = userDao.getInfo(username);
        System.out.println(list);
        System.out.println("123123");
        return null;
    }
}


//@Service
//public class UserServiceImpl implements IUserService{
//
//
//    @Autowired
//    private UserDao userDao;
//
//    
//    @Override
//    public String getmessage(UserDto user) throws UserException {
////        String username = user.getUsername();
////        String username=user.getParameter("username");
////        List<Map<String,Object>> list =userDao.getInfo(username);
////        System.out.println(list.get(0).get("username"));
//        return null;
//    }
//    }

11）user/dto下创建UserDto.java文件：

package com.ekingwin.bas.cloud.user.dto;

public class UserDto {
    private String id;
    private String username;
    private String password;
    private String company;
    private String age;
    private String sex;

    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }

    public String getUsername() {
        return username;
    }

    public void setUsername(String username) {
        this.username = username;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    public String getCompany() {
        return company;
    }

    public void setCompany(String company) {
        this.company = company;
    }

    public String getAge() {
        return age;
    }

    public void setAge(String age) {
        this.age = age;
    }

    public String getSex() {
        return sex;
    }

    public void setSex(String sex) {
        this.sex = sex;
    }
}

 12）user/dao下创建IUserDao.java文件：

package com.ekingwin.bas.cloud.user.dao;

import java.util.List;
import java.util.Map;

import org.apache.ibatis.annotations.Param;

import com.ekingwin.bas.cloud.user.dao.entity.User;
import com.ekingwin.bas.cloud.utils.BasMapper;


public interface IUserDao extends BasMapper<User>{
    public User login(User user);
    public List<Map<String, Object>> getInfo(@Param("username")String username);
}

13）在user/dao/entity下创建User.java文件：

package com.ekingwin.bas.cloud.user.dao.entity;

import javax.persistence.Id;
import javax.persistence.Table;

//@Table(name = "user")
public class User {

    @Id
    private String id;
    private String username;
    private String password;
    private String company;
    private String age;
    private String sex;

    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }

    public String getUsername() {
        return username;
    }

    public void setUsername(String username) {
        this.username = username;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    public String getCompany() {
        return company;
    }

    public void setCompany(String company) {
        this.company = company;
    }

    public String getAge() {
        return age;
    }

    public void setAge(String age) {
        this.age = age;
    }

    public String getSex() {
        return sex;
    }

    public void setSex(String sex) {
        this.sex = sex;
    }
}

4、启动Tomcat在浏览器上即可。
