SSM整合
作者:互联网
整合SSM框架
环境要求
环境:
-
IDEA
-
MySQL 5.7.19
-
Tomcat 9
-
Maven 3.6
要求:
-
需要熟练掌握MySQL数据库,Spring,JavaWeb及MyBatis知识,简单的前端知识;
数据库环境
CREATE DATABASE `ssmbuild`;
USE `ssmbuild`;
DROP TABLE IF EXISTS `books`;
CREATE TABLE `books` (
`bookID` INT(10) NOT NULL AUTO_INCREMENT COMMENT '书id',
`bookName` VARCHAR(100) NOT NULL COMMENT '书名',
`bookCounts` INT(11) NOT NULL COMMENT '数量',
`detail` VARCHAR(200) NOT NULL COMMENT '描述',
KEY `bookID` (`bookID`)
) ENGINE=INNODB DEFAULT CHARSET=utf8;
INSERT INTO `books`(`bookID`,`bookName`,`bookCounts`,`detail`)VALUES
(1,'Java',1,'从入门到放弃'),
(2,'MySQL',10,'从删库到跑路'),
(3,'Linux',5,'从进门到进牢');
基本环境搭建
-
新建一Maven项目!ssmbuild , 添加web的支持
-
导入相关的pom依赖!

-
Maven资源过滤设置
<!--静态资源导出问题--> <build> <resources> <resource> <directory>${basedir}/src/main/webapp</directory> </resource> <resource> <directory>${basedir}/src/main/resources</directory> </resource> <resource> <directory>${basedir}/src/main/java</directory> <includes> <include>**/*.xml</include> <include>**/*.properties</include> </includes> </resource> </resources> </build>
-
建立基本结构和配置框架!
-
com.sheng.pojo
-
com.sheng.dao
-
com.shengc.service
-
com.sheng.controller
-
mybatis-config.xml
<?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> <settings> <setting name="logImpl" value="STDOUT_LOGGING" /> </settings> <!--配置数据源,交给Spring去做--> <typeAliases> <package name="com.sheng.pojo"/> </typeAliases> <mappers> <mapper class="com.sheng.dao.BookMapper"/> </mappers> </configuration>
-
application.xml
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd"> <import resource="classpath:spring-dao.xml"/> <import resource="classpath:spring-service.xml"/> <import resource="classpath:spring-mvc.xml"/> </beans>
-
Mybatis层编写
-
数据库配置文件 database.properties
jdbc.driver=com.mysql.jdbc.Driver # 如果使用的是MySQL8.0+,增加一个时区的配置;&serverTimezone=Asia/Shanghai jdbc.url=jdbc:mysql://localhost:3306/Mybatis?serverTimezone=UTC&useUnicode=true&characterEncoding=utf8 jdbc.username=root jdbc.password=sxf000218
-
pojo层 实体类
package com.sheng.pojo; public class Books { private int bookID; private String bookName; private int bookCounts; private String detail; public Books() { } public Books(int bookID, String bookName, int bookCounts, String datail) { this.bookID = bookID; this.bookName = bookName; this.bookCounts = bookCounts; this.detail = detail; } public int getBookID() { return bookID; } public void setBookID(int bookID) { this.bookID = bookID; } public String getBookName() { return bookName; } public void setBookName(String bookName) { this.bookName = bookName; } public int getBookCounts() { return bookCounts; } public void setBookCounts(int bookCounts) { this.bookCounts = bookCounts; } public String getDetail() { return detail; } public void setDetail(String detail) { this.detail = detail; } @Override public String toString() { return "Books{" + "bookID=" + bookID + ", bookName='" + bookName + '\'' + ", bookCounts=" + bookCounts + ", detail='" + detail + '\'' + '}'; } }
-
dao层 Mapper接口
package com.sheng.dao; import com.sheng.pojo.Books; import org.apache.ibatis.annotations.Param; import java.awt.print.Book; import java.util.List; public interface BookMapper { //增加一本书 int addBook(Books books); //删除一本书 int deleteBookById(@Param("bookID") int id); //更新一本书 int updateBook(Books books); //查询一本书 Books queryBookById(@Param("bookID")int id); //查询全部的书 List<Books> queryAllBook(); //根据名字查询书籍 Books queryBookName(@Param("bookName") String bookName); }
-
dao层 Mapper接口的配置
<?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.sheng.dao.BookMapper"> <insert id="addBook" parameterType="Books"> insert into ssmbuild.books (bookName, bookCounts, detail) values (#{bookName},#{bookCounts},#{detail}); </insert> <delete id="deleteBookById" parameterType="int"> delete from ssmbuild.books where bookID = #{bookID} </delete> <update id="updateBook" parameterType="Books"> update ssmbuild.books set bookName = #{bookName},bookCounts= #{bookCounts},detail = #{detail} where bookID = #{bookID}; </update> <select id="queryBookById" resultType="Books"> select * from ssmbuild.books where bookID = #{bookID} </select> <select id="queryAllBook" resultType="Books"> select * from ssmbuild.books </select> <select id="queryBookName" resultType="Books"> select * from ssmbuild.books where bookName = #{bookName} </select> </mapper>
-
service层 的接口
package com.sheng.service; import com.sheng.pojo.Books; import org.apache.ibatis.annotations.Param; import java.util.List; public interface BookService { //增加一本书 int addBook(Books books); //删除一本书 int deleteBookById(int id); //更新一本书 int updateBook(Books books); //查询一本书 Books queryBookById(int id); //查询全部的书 List<Books> queryAllBook(); //根据名字查询书籍 Books queryBookByName(@Param("bookName") String bookName); }
-
service层 的实现类
package com.sheng.service; import com.sheng.dao.BookMapper; import com.sheng.pojo.Books; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service; import java.util.List; //@Service public class BookServiceImpl implements BookService { //service调dao层 : 组合dao //@Autowired private BookMapper bookMapper; public void setBookMapper(BookMapper bookMapper) { this.bookMapper = bookMapper; } public int addBook(Books books) { return bookMapper.addBook(books); } public int deleteBookById(int id) { return bookMapper.deleteBookById(id); } public int updateBook(Books books) { return bookMapper.updateBook(books); } public Books queryBookById(int id) { return bookMapper.queryBookById(id); } public List<Books> queryAllBook() { return bookMapper.queryAllBook(); } public Books queryBookByName(String bookName) { return bookMapper.queryBookName(bookName); } }
Spring操作
-
配置Spring整合MyBatis,我们这里数据源使用c3p0连接池;
-
我们去编写Spring整合Mybatis的相关的配置文件;
