SSM配置地狱？一篇整合模板迅速解决！【建议收藏】

Spring+SpringMVC+Mybatis

环境配置
IDEA
MySQL 5.7
Tomcat 8.5
Maven 3.6
创建数据库

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=utf8INSERT  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');

编写数据库对应的实体类com.longdi.pojo.Books
导入lombok在pom.xml中

package com.longdi.pojo;import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;/*** @author: 龍弟* @description* @date: 2021/9/27 20:22*/
@Data
@AllArgsConstructor
@NoArgsConstructor
public class Books {private int bookID;private String bookName;private int bookCounts;private String detail;
}

导入相关的pom依赖

资源过滤设置

<build><resources><resource><directory>src/main/java</directory><includes><include>**/*.properties</include><include>**/*.xml</include></includes><filtering>false</filtering></resource><resource><directory>src/main/resources</directory><includes><include>**/*.properties</include><include>**/*.xml</include></includes><filtering>false</filtering></resource></resources>
</build>

Mybatis层编写
创建mybatis-config.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configurationPUBLIC "-//mybatis.org//DTD Config 3.0//EN""http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration><settings><setting name="logImpl" value="STDOUT_LOGGING"/></settings><typeAliases><package name="com.longdi.pojo"/></typeAliases><mappers><mapper class="com.longdi.dao.BookMapper"/></mappers>
</configuration>

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/ssmbuild?useSSL=true&useUnicode=true&characterEncoding=utf8
jdbc.username=root
jdbc.password=123456

编写Dao层的Mapper接口

package com.longdi.dao;import com.longdi.pojo.Books;
import org.apache.ibatis.annotations.Param;import java.util.List;/*** @author: 龍弟* @description* @date: 2021/9/27 20:32*/
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();Books queryBookByName(@Param("bookName")String bookName);}

编写接口对应的 Mapper.xml 文件。需要导入MyBatis的包；

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapperPUBLIC "-//mybatis.org//DTD Config 3.0//EN""http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.longdi.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.booksset bookName=#{bookName},bookCounts=#{bookCounts},detail=#{detail}where bookID=#{bookID};</update><select id="queryBookById" resultType="Books">select * from ssmbuild.bookswhere bookID=#{bookId}</select><select id="queryAllBook" resultType="Books">select * from ssmbuild.books</select><select id="queryBookByName" resultType="Books">select * from ssmbuild.books where bookName=#{bookName}</select></mapper>

编写Service层的接口

package com.longdi.service;import com.longdi.pojo.Books;import java.util.List;/*** @author: 龍弟* @description* @date: 2021/9/27 21:03*/
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();Books queryBookByName(String bookName);
}

Service层的实现类

package com.longdi.service;import com.longdi.dao.BookMapper;
import com.longdi.pojo.Books;
import org.springframework.stereotype.Service;import java.util.List;/*** @author: 龍弟* @description* @date: 2021/9/27 21:05*/public class BookServiceImpl implements BookService{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) {System.out.println("BookServiceImpl:updateBook=>"+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.queryBookByName(bookName);}
}

Spring整合Mybatis spring-dao.xml
以下为spring层

<?xml version="1.0" encoding="UTF-8"?>

spring-service.xml文件

以下为SpringMVC层
配置web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"version="4.0"><!--DispatcherServlet--><servlet><servlet-name>DispatcherServlet</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><init-param><param-name>contextConfigLocation</param-name><!--一定要注意:我们这里加载的是总的配置文件，之前被这里坑了！--><param-value>classpath:applicationContext.xml</param-value></init-param><load-on-startup>1</load-on-startup></servlet><servlet-mapping><servlet-name>DispatcherServlet</servlet-name><url-pattern>/</url-pattern></servlet-mapping><!--encodingFilter--><filter><filter-name>encodingFilter</filter-name><filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class><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><!--Session过期时间--><session-config><session-timeout>15</session-timeout></session-config></web-app>

以上为SSM的环境配置，下面编写Controller层和视图层，实现书籍的CRUD功能

controller层书籍的增删改查功能

import java.util.ArrayList;
import java.util.List;/*** @author: 龍弟* @description* @date: 2021/9/27 22:47*/
@Controller
@RequestMapping("/book")
public class BookController {@Autowired@Qualifier("BookServiceImpl")private BookService bookService;@RequestMapping("/allBook")public String list(Model model) {List<Books> list = bookService.queryAllBook();model.addAttribute("list", list);return "allBook";}//跳转到增加书籍页面@RequestMapping("/toAddBook")public String toAddPaper(){return "addBook";}//添加书籍的请求@RequestMapping("/addBook")public String addBook(Books books){System.out.println("addBook=>"+books);bookService.addBook(books);return "redirect:/book/allBook";}//跳转到修改页面@RequestMapping("toUpdateBook")public String toUpdatePaper(int id,Model model){Books books = bookService.queryBookById(id);model.addAttribute("book",books);return "updateBook";}//修改书籍@RequestMapping("updateBook")public String updateBook(Books books){System.out.println("updateBook=>"+books);int i=bookService.updateBook(books);if(i>0){System.out.println("添加books成功"+books);}return "redirect:/book/allBook";}//删除书籍@RequestMapping("/deleteBook/{bookId}")public String deleBook(@PathVariable("bookId") int id){bookService.deleteBookById(id);return "redirect:/book/allBook";}//查询书籍@RequestMapping("/queryBook")public String queryBook(String queryBookName,Model model){Books books=bookService.queryBookByName(queryBookName);System.err.println("queryBook=>"+books);List<Books> list=new ArrayList<Books>();list.add(books);if(books==null){list=bookService.queryAllBook();model.addAttribute("error","未查到");}model.addAttribute("list",list);return "allBook";}}
