SSM(Spring +SpringMVC + Mybatis)框架搭建

SSM(Spring +SpringMVC + Mybatis)框架的搭建

最近經過學習別人博客發表的SSM搭建Demo,嘗試去搭建一個簡單的SSMDemo---實現的功能是對用戶增刪改查的操做
參考博客連接javascript

工程結構

src目錄結構
css

工程所需jar包(jar包下載地址
html

一、User實體類

package com.ssm.ljn.user.model;

import java.io.Serializable;

/**
 * 
 * <p>
 * <b>用戶實體類</b></>
 * 
 * @author Luojiening
 */
public class User implements Serializable {

    private int id;
    private String username;
    private int age;
    private String sex;

    public User() {
        super();
    }

    public User(int id, String username, int age, String sex) {
        super();
        this.id = id;
        this.username = username;
        this.age = age;
        this.sex = sex;
    }

    public int getId() {
        return id;
    }

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

    public String getUsername() {
        return username;
    }

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

    public int getAge() {
        return age;
    }

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

    public String getSex() {
        return sex;
    }

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

二、dao層

package com.ssm.ljn.user.dao;

import java.util.List;

import org.springframework.stereotype.Repository;

import com.ssm.ljn.user.model.User;

@Repository
public interface IUserDao {
    
    void saveUser(User user);
    
    boolean updateUser(User user);
    
    boolean deleteUser(int id);
    
    User queryUserById(int id);
    
    List<User> queryAllUser();
}

三、實現Dao接口(主要是SQL語句)

<?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">    
<!--     
    namespace:必須與對應的接口全類名一致  UserMapper.java  
    id :必須與對應接口的某個對應的方法名一致即必需要和UserMapper.java接口中的方法同名。  
 -->
<mapper namespace="com.ssm.ljn.user.dao.IUserDao">
    <!-- 新增用戶-->
    <insert id="saveUser" parameterType="com.ssm.ljn.user.model.User">
        insert into User(user_id,user_name,user_age,user_sex) value(#{id},#{username},#{age},#{sex})
    </insert>
    <!-- 修改用戶 -->
    <update id="updateUser" parameterType="com.ssm.ljn.user.model.User">
        update User set user_name=#{username},user_age=#{age},user_sex=#{sex} where user_id=#{id}
    </update>
    <!-- 刪除用戶 -->
    <delete id="deleteUser" parameterType="com.ssm.ljn.user.model.User">
        delete from User where user_id = #{id}
    </delete>
    <!-- 根據id查找用戶 -->
    <select id="queryUserById" parameterType="int" resultType="com.ssm.ljn.user.model.User">
        select user_id id,user_name username,user_age age,user_sex sex from User where user_id=#{id}
    </select>
    <!-- 查詢全部用戶 -->
    <select id="queryAllUser" resultType="com.ssm.ljn.user.model.User">
        select user_id id,user_name userName,user_age age,user_sex sex from User order by id
    </select>
</mapper>

四、spring-mybatis配置文件

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

            </tx:attributes>
        </tx:advice>
</beans>

五、mybatis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>
    <typeAliases>
        <package name="com.ssm.ljn.*.model"/>
    </typeAliases>
    
    <!-- mybatis分頁插件 -->
    <plugins>
        <plugin interceptor="com.github.pagehelper.PageHelper"></plugin>
    </plugins>
</configuration>

六、springmvc配置文件

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

        ">
    
     <!-- 掃描註解包  -->
       <context:component-scan base-package="com.ssm.ljn.user.action"></context:component-scan> 
      <!-- 配置sprigmvc視圖解析器:解析邏輯試圖

       <mvc:annotation-driven />
        <!-- 2.配置靜態資源訪問 -->
       <mvc:default-servlet-handler/>
       <!-- 使用CGLib動態代理技術 -->
       <aop:aspectj-autoproxy proxy-target-class="true" />
</beans>

七、jdbc.properties

#jdbc.properties
jdbc.driver = com.mysql.jdbc.Driver
jdbc.url = jdbc:mysql://127.0.0.1:3306/ssm?useUnicode=true&characterEncoding=utf8&useSSL=false
jdbc.username = root
jdbc.password = 123456

八、log4j.xml

### set log levels ###  
log4j.rootLogger = INFO , console , debug , error  

### console ###  
log4j.appender.console = org.apache.log4j.ConsoleAppender  
log4j.appender.console.Target = System.out  
log4j.appender.console.layout = org.apache.log4j.PatternLayout  
log4j.appender.console.layout.ConversionPattern = %-d{yyyy-MM-dd HH\:mm\:ss} [%p]-[%c] %m%n

log4j.appender.debug.Threshold = INFO  
log4j.appender.debug.layout = org.apache.log4j.PatternLayout  
log4j.appender.debug.layout.ConversionPattern = %-d{yyyy-MM-dd HH\:mm\:ss} [%p]-[%c] %m%n  

### exception ###

log4j.logger.druid.sql.ResultSet=warn,stdout

八、web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app  version="2.4"  xmlns="http://java.sun.com/xml/ns/j2ee"

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

                  xmlns:web="http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"

                xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee

                  http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

  </listener>
 
 <!-- 配置SpringMVC核心控制器 -->
  <servlet>

  </filter-mapping>
 
  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
</web-app>

十、service層及其實現類

package com.ssm.ljn.user.service;

import java.util.List;

import org.springframework.stereotype.Service;

import com.ssm.ljn.user.model.User;

public interface IUserService {
    
    void saveUser(User user);
    
    boolean updateUser(User user);
    
    boolean deleteUser(int id);
    
    User queryUserById(int id);
    
    List<User> queryAllUser();
}
package com.ssm.ljn.user.service.impl;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

import com.ssm.ljn.user.dao.IUserDao;
import com.ssm.ljn.user.model.User;
import com.ssm.ljn.user.service.IUserService;

@Service("userService")
@Transactional
public class UserService implements IUserService{
    
    @Autowired
    private IUserDao iUserDao;
    
    @Override
    public void saveUser(User user) {
        iUserDao.saveUser(user);
    }

    @Override
    public boolean updateUser(User user) {
        return iUserDao.updateUser(user);
    }

    @Override
    public boolean deleteUser(int id) {
        return iUserDao.deleteUser(id);
    }

    @Override
    public User queryUserById(int id) {
        return iUserDao.queryUserById(id);
    }

    @Override
    public List<User> queryAllUser() {
        return iUserDao.queryAllUser();
    }
}

十一、創建controllor

package com.ssm.ljn.user.action;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;

import com.github.pagehelper.PageHelper;
import com.github.pagehelper.PageInfo;
import com.ssm.ljn.user.model.User;
import com.ssm.ljn.user.service.IUserService;;


@Controller
@RequestMapping("/user")
public class UserAction {
    
    @Autowired
    private IUserService iUserService;
    
    /**
    *跳轉到添加用戶界面
    */
   @RequestMapping("toAddUser")
   public String toAddUser(){
       return "addUser";
   }
   
   /**
    * 添加用戶並重定向  
    * @param model
    * @param user
    * @return
    */
   @RequestMapping("addUser") 
   public String addUser(Model model,User user){
       if(user != null){
           iUserService.saveUser(user);
       }
       return "redirect:/user/userInfo";
   }

   /**
    * 修改用戶
    * @param model
    * @param request
    * @param user
    * @return
    */
   @RequestMapping("updateUser")  
   public String UpdateUser(Model model,User user){
            if(iUserService.updateUser(user)){  
                   user = iUserService.queryUserById(user.getId());  
                   model.addAttribute("user", user);  
                   return "redirect:/user/userInfo";  
               } 
        return "/error";  
   }

   /**
    * 查詢全部用戶
    * @param request
    * @param model
    * @return
    */
   @RequestMapping("getAllUser")  
   public String getAllUser(Model model){
       List<User> user = iUserService.queryAllUser();
       model.addAttribute("userList",user);
       return "allUser";
   }

   /**
    * 查詢單個用戶
    * @param id
    * @param request
    * @param model
    * @return
    */
   @RequestMapping("/getUser")  
   public String getUser(int id,Model model){
       model.addAttribute("user", iUserService.queryUserById(id));  
       return "editUser";
   }
   /**
    * 根據id刪除用戶
    * @param id
    * @param request
    * @param response
    */
   @RequestMapping("/delUser") 
   public String deleteUser(int id,Model model){
       model.addAttribute("user", iUserService.deleteUser(id));  
       return "redirect:/user/userInfo";
   }
   
   @RequestMapping("userInfo")
   public String getUsers(@RequestParam(value="pn",defaultValue="1")Integer pn,Model model){
       //從第一條開始 每頁查詢五條數據
       PageHelper.startPage(pn, 5);
       List<User> users = iUserService.queryAllUser();
       //將用戶信息放入PageInfo對象裏
       PageInfo page = new PageInfo(users,5);
       model.addAttribute("pageInfo", page);
       return "allUser";
   }
}

WebContent目錄結構
java

index界面mysql

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<%
    pageContext.setAttribute("path", request.getContextPath());
%>
<!DOCTYPE htm >

數據庫建表語句,相對較爲簡單,也沒有任何的約束條件web

CREATE TABLE `user` (
  `user_id` int(50) NOT NULL,
  `user_name` varchar(20) DEFAULT NULL,
  `user_age` int(10) DEFAULT NULL,
  `user_sex` varchar(2) DEFAULT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

在參考實現過程當中遇到不少的問題,有的是jar的缺失引發的,有的是路徑錯誤引發的,主要經過百度相關異常從而找到相應的解決方法。
最後,用戶增刪改查的界面調試成功
