配置Maven

  • 自行选择Maven工具(不建议使用IDEA自带)
  • 自行配置Maven项目所需的各种参数设置
  • 自行指定本地存储位置(避免依赖默认路径),推荐采用**$path变量**来表示本地项目的存储位置(避免使用预设配置文件位置)

    </project>

建立基本的包结构

在这里插入图片描述

新建实体类

复制代码
    package com.cloud.pojo;
    
    import lombok.AllArgsConstructor;
    import lombok.Data;
    import lombok.NoArgsConstructor;
    
    @Data
    @AllArgsConstructor
    @NoArgsConstructor
    public class Books {
    private int bookID;
    private String bookName;
    private int bookCounts;
    private String detail;
    }

新建查询接口

复制代码
    package com.cloud.dao;
    
    import com.cloud.pojo.Books;
    
    import java.util.List;
    
    public interface BookMapper {
    
    //增
    int addBooks(Books books);
    
    //删
    int deleteBookById(int id);
    
    //查
    Books queryBookById(int id);
    
    List<Books> queryAllBooks();
    
    //改
    int updateBook(Books books);
    }

实现查询接口

复制代码
    <?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.cloud.dao.BookMapper">
    
    <insert id="addBooks" parameterType="com.cloud.pojo.Books">
        insert into 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="com.cloud.pojo.Books">
        update ssmbuild.books
        set bookName=#{bookName},bookCounts=#{bookCounts},detail=#{detail}
        where bookID = #{bookID};
    </update>
    
    <select id="queryBookById" resultType="com.cloud.pojo.Books">
        select * from ssmbuild.books where bookID = #{bookID};
    </select>
    
    <select id="queryAllBooks" resultType="com.cloud.pojo.Books">
        select * from ssmbuild.books;
    </select>
    </mapper>

编写Mybatis的配置文件

在resources文件夹下新建mybatis-config.xml

复制代码
    <?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>
    <!--取别名-->
    <typeAliases>
        <package name="com.cloud.pojo"/>
    </typeAliases>
    
    <mappers>
        <mapper class="com.cloud.dao.BookMapper"/>
    </mappers>
    
    </configuration>

编写业务层

复制代码
    package com.cloud.service;
    
    import com.cloud.pojo.Books;
    
    import java.util.List;
    
    public interface BookService {
    //增
    int addBooks(Books books);
    
    //删
    int deleteBookById(int id);
    
    //查
    Books queryBookById(int id);
    
    List<Books> queryAllBooks();
    
    //改
    int updateBook(Books books);
    }

编写业务层实现

复制代码
    package com.cloud.service;
    
    import com.cloud.dao.BookMapper;
    import com.cloud.pojo.Books;
    
    import java.util.List;
    
    public class BookServiceImpl implements BookService {
    
    //service层调dao层
    private BookMapper bookMapper;
    
    public void setBookMapper(BookMapper bookMapper) {
        this.bookMapper = bookMapper;
    }
    
    public int addBooks(Books books) {
        return bookMapper.addBooks(books);
    }
    
    public int deleteBookById(int id) {
        return bookMapper.deleteBookById(id);
    }
    
    public Books queryBookById(int id) {
        return bookMapper.queryBookById(id);
    }
    
    public List<Books> queryAllBooks() {
        return bookMapper.queryAllBooks();
    }
    
    public int updateBook(Books books) {
        return bookMapper.updateBook(books);
    }
    }

编写Spring配置文件

spring整合dao层

在resources文件夹下新建spring-dao.xml

复制代码
    <?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:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans.xsd
       http://www.springframework.org/schema/context
       https://www.springframework.org/schema/context/spring-context.xsd">
    
    <!--关联数据库配置文件-->
    <context:property-placeholder location="classpath:database.properties"/>
    
    <!--连接池
        dbcp:半自动化,不能自动连接
        c3p0:自动化操作:自动化的加载配置文件,并且可以自动设置到对象中
        druid,hikari-->
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <property name="driverClass" value="${jdbc.driver}"/>
        <property name="jdbcUrl" value="${jdbc.url}"/>
        <property name="user" value="${jdbc.username}"/>
        <property name="password" value="${jdbc.password}"/>
    </bean>
    
    <!--sqlSessionFactory-->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource"/>
        <!--绑定MyBatis的配置文件-->
        <property name="configLocation" value="classpath:mybatis-config.xml"/>
    </bean>
    
    <!--配置dao接口扫描包,动态实现Dao接口可以注入到Spring容器中-->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <!--注入sqlSessionFactory-->
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
        <!--要扫描的dao包-->
        <property name="basePackage" value="com.cloud.dao"/>
    </bean>
    </beans>

spring整合service层

在resources文件夹下新建spring-service.xml

复制代码
    <?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:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans.xsd
       http://www.springframework.org/schema/context
       https://www.springframework.org/schema/context/spring-context.xsd">
    
    <!--扫描service下的包-->
    <context:component-scan base-package="com.cloud.service"/>
    <!--将所有的业务类注入到Spring,可以通过配置或者注解实现-->
    
    <!--声明事务配置-->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <!--注入数据源-->
        <property name="dataSource" ref="dataSource"/>
    </bean>
    
    </beans>

整合springmvc

编写web.xml文件

如果创建项目时没有生成web.xml,右键项目添加web支持

复制代码
    <?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">
    <!--DispatchServlet-->
    <servlet>
        <servlet-name>springmvc</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:applicationContext.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>springmvc</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>
    
    <!--乱码过滤-->
    <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>
    </web-app>
编写spring-mvc.xml文件

在resources文件夹下新建spring-mvc.xml

复制代码
    <?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:mvc="http://www.springframework.org/schema/mvc"

       http://www.springframework.org/schema/mvc
       https://www.springframework.org/schema/mvc/spring-mvc.xsd
       http://www.springframework.org/schema/context
       https://www.springframework.org/schema/context/spring-context.xsd">
    
    <!--注解驱动-->
    <mvc:annotation-driven/>
    <!--静态资源过滤-->
    <mvc:default-servlet-handler/>
    <!--扫描包:controller-->
    <context:component-scan base-package="com.cloud.controller"/>
    <!--视图解析器-->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/jsp/"/>
        <property name="suffix" value=".jsp"/>
    </bean>
    </beans>

整合Spring配置文件
