ssm整合超详细步骤

简介

1. 首先目录 java根目录、resources配置文件目录、webapp目录
2. java 目录设为Sources Root resources 设为Resources Root
3. java 目录下面建必须有的四个文件包
   • Controller
   • Mapper
   • Service
     • 建一个Impl包
   • Pojo （存放实体类的包）
4. resources
   • heuet.edu.Mapper
   • spring
     • applicationContext.xml
     • spring-servlet.xml
     • spring-mybatis.xml
     • spring-context.xml
   • db.properties
   • log4j.properties

首先导入jar包

<properties>
    <project.build.sourceEncoding>UTF-8project.build.sourceEncoding>
    <maven.compiler.source>1.7maven.compiler.source>
    <maven.compiler.target>1.7maven.compiler.target>
    <spring.version>5.0.8.RELEASEspring.version>

配置db.properties

注意如果mysql-connection-java 的版本高的话url后面加上serverTimezone=UTC

driver用com.mysql.cj.jdbc.Driver

低版本的话 用com.mysql.jdbc.Driver

可以都试试

jdbc.driver=com.mysql.cj.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/mysql?3useUnicode=true&characterEncoding=utf8&serverTimezone=UTC
#jdbc.url=jdbc:mysql://localhost:3306/mysql
jdbc.username=root
jdbc.password=123456

配置log4j.properties

#定义log输出级别
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
#可以灵活的指定日志输出格是，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

#mybatis显示sql语句配置
log4j/logger.heuet.edu.Mapper=DEBUG
#文件大小制定尺寸的时候产生一个新文件
log4j.appender.File=org.apache.log4j.RollingFileAppender
#指定输出目录，这里会放tomcat之下
log4j.appender.File.File=E://idea//log4j//log.log
#定义文件最大大小
log4j.appender.File.MaxFileSize=100MB
#输出所有日志，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

配置完毕

做一个简单的登陆功能

1. 建立一个数据库found 并创建一个student表

2. 建立两个字段username 和password （自己加一个值 username 123456 ）

3. 然后在Pojo文件夹下创建一个User实体类

   • package heuet.edu.Pojo;
     
     public class User {
         private String username;
         private String password;
     
         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;
         }
     }
     
     

4. 在Controller包下创建一个UserController的类

   • package heuet.edu.Controller;
     
     import heuet.edu.Pojo.User;
     import heuet.edu.Service.UserService;
     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 org.springframework.web.bind.annotation.ResponseBody;
     
     @Controller
     @RequestMapping("/user")
     public class UserController {
     
         @Autowired
         private UserService userService;
         @RequestMapping("/login")
     
         public String login( User user,Model model){
             user=userService.get(user);
             model.addAttribute("user",user);
             return "/login/login";
         }
     }
     
     

5. 在Mapper下创建一个UserMapper的接口

   • package heuet.edu.Mapper;
     
     import heuet.edu.Pojo.User;
     
     public interface UserMapper {
         User select(User user);
     }
     
     

6. 在resources 中的heuet.edu.Mapper的包下创建一个UserMapper.xml文件

   • 
     
     <mapper namespace="heuet.edu.Mapper.UserMapper">
     <select id="select" parameterType="heuet.edu.Pojo.User" resultType="heuet.edu.Pojo.User">
         select *
         from found.student
         where
         username=#{username}
         and
         password=#{password}
     select>
     
     mapper>
     

7. 在Service包下创建一个接口UserService

   • package heuet.edu.Service;
     
     
     import heuet.edu.Pojo.User;
     
     public interface UserService {
         User get(User user);
     }
     
     

   • 在Service包中的Impl包下创建一个UserServiceImpl的UserService实现类

     • package heuet.edu.Service.Impl;
       
       import heuet.edu.Mapper.UserMapper;
       import heuet.edu.Pojo.User;
       import heuet.edu.Service.UserService;
       import org.springframework.beans.factory.annotation.Autowired;
       import org.springframework.stereotype.Service;
       import org.springframework.transaction.annotation.Transactional;
       
       @Service("userService")
       public class UserServiceImpl implements UserService {
       
           @Autowired
           private UserMapper userMapper;
           @Transactional
           public User get(User user) {
       
               return userMapper.select(user);
           }
       }
       
       

至此所有的后台代码都写完了下面只需写两个前端网页

在webapp下创建一个login文件夹 和一个login.jsp

login文件夹下放一个user.jsp

首先login.jsp

<%@ page contentType="text/html;charset=UTF-8" language="java" %>


    



    账号：

    密码：

    

user.jsp

<%@ page contentType="text/html;charset=UTF-8" language="java" %>


    



欢迎您${user.username}

注意

• 看一下你JDK包下jre\lib\ext是否有mysql-connector-java-8.0.13.jar 或者是否与所引入的依赖的版本号相同如果不一样的话有可能报错，版本过低也有可能报错。当时就是因为这个问题困扰了我两天。
• 希望这个能够帮助到你。
