前言

根据自己的环境参考狂神的视频进行了SSM框架整合,用于备忘

SSM框架整合步骤

1. 创建数据库

2. IDEA创建maven项目.在pom.xml中设设置java conpiler版本(jdk13)

3. 导入依赖 jnuit 数据库驱动 数据库连接 Severlet JSp

4. maven 资源过滤

 4.0.0
 
  
   
    src/main/java
    
     **/*.properties
     **/*.xml
    
    false
   
   
    src/main/resources
    
     **/*.properties
     **/*.xml
    
    false
   
  
 

 org.example
 ssm
 1.0-SNAPSHOT
 
  13
  13
 
 
  
  
   junit
   junit
   4.12
  
  
  
   mysql
   mysql-connector-java
   5.1.47
  
  
  
   com.mchange
   c3p0
   0.9.5.2
  

  
  
   javax.servlet
   servlet-api
   2.5
  
  
   javax.servlet.jsp
   jsp-api
   2.2
  
  
   javax.servlet
   jstl
   1.2
  

  
  
   org.mybatis
   mybatis
   3.5.2
  
  
   org.mybatis
   mybatis-spring
   2.0.6
  

  
  
   org.springframework
   spring-webmvc
   5.3.4
  
  
   org.springframework
   spring-jdbc
   5.3.4
  
 

5. 创建两个项目的目录结构以及Spring 和 Mybatis的配置文件

Mybatis

6. 配置数据库属性

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/ssmbuild?useSSL=false&useUnicode=true&characterEncoding=UTF-8&serverTimezone=UTC
jdbc.username=root
jdbc.password=root

7. 创建Book实体类(使用lombok插件),编写Dao层mapper接口,在mybatis配置中注册mapper

package com.projectname.pojo;

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;

@Data
@AllArgsConstructor
@NoArgsConstructor
public class Book {
 private int bookID;
 private String bookName;
 private int bookCounts;
 private String detail;

}

package com.projectname.dao;

import com.projectname.pojo.Book;

import java.util.List;

public interface DaoBook {
 //增加一个Book
 int addBook(Book book);

 //根据id删除一个Book
 int deleteBookById(int id);

 //更新Book
 int updateBook(Book books);

 //根据id查询,返回一个Book
 Book queryBookById(int id);

 //查询全部Book,返回list集合
 List queryAllBook();
}

 
 
  insert into ssmbuild.books(bookName,bookCounts,detail)
  values (#{bookName}, #{bookCounts}, #{detail})
 

 
 
  delete from ssmbuild.books where bookID=#{bookID}
 

 
 
  update ssmbuild.books
  set bookName = #{bookName},bookCounts = #{bookCounts},detail = #{detail}
  where bookID = #{bookID}
 

 
 
  select * from ssmbuild.books
  where bookID = #{bookID}
 

 
 
  SELECT * from ssmbuild.books
 

8. 编写service层的接口和实现类代码

package com.projectname.service;

import com.projectname.pojo.Book;

import java.util.List;

public interface BookService {
 //增加一个Book
 int addBook(Book book);
 //根据id删除一个Book
 int deleteBookById(int id);
 //更新Book
 int updateBook(Book books);
 //根据id查询,返回一个Book
 Book queryBookById(int id);
 //查询全部Book,返回list集合
 List queryAllBook();
}

package com.projectname.service;

import com.projectname.dao.BookMapper;
import com.projectname.pojo.Book;

import java.util.List;

public class BookServiceImpl implements BookService {

 //调用dao层的操作，设置一个set接口，方便Spring管理
 private BookMapper bookMapper;

 public void setBookMapper(BookMapper bookMapper) {
  this.bookMapper = bookMapper;
 }

 public int addBook(Book book) {
  return bookMapper.addBook(book);
 }

 public int deleteBookById(int id) {
  return bookMapper.deleteBookById(id);
 }

 public int updateBook(Book books) {
  return bookMapper.updateBook(books);
 }

 public Book queryBookById(int id) {
  return bookMapper.queryBookById(id);
 }

 public List queryAllBook() {
  return bookMapper.queryAllBook();
 }
}

Spring

9. 使用Spring编写Mybatis配置文件:spring-dao.xml

10. Spring 整合service层

spring-service

Spring MVC层

11. configuate the web.xml

 
 
 
  DispatcherServlet
  org.springframework.web.servlet.DispatcherServlet
  
   contextConfigLocation
   
   classpath:applicationContext.xml
  
  1
 
 
  DispatcherServlet
  /
 

 
 
  encodingFilter
  
   org.springframework.web.filter.CharacterEncodingFilter
  
  
   encoding
   utf-8
  
 
 
  encodingFilter
  /*
 

 
 
  15
 

12. spring-mvc.xml

13. configuate applicationContext.xml

一些杂七杂八的配置

14. 添加日志功能

15. add lib

File -> Project Structure->Artifacts
Type -> Bundle

new directory lib
