2021-09-14 20:53:18

环境要求

环境：IDEA、MySQL5.7.19、Tomact8.5、Mavec3.6.1

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‘,
PRIMARY KEY (`bookID`),
KEY `bookID` (`bookID`)
) ENGINE=InnoDB AUTO_INCREMENT=4 DEFAULT CHARSET=utf8;

INSERT INTO `books` VALUES (‘1‘, ‘Java‘, ‘1213‘, ‘从入门到放弃‘);
INSERT INTO `books` VALUES (‘2‘, ‘MySQL‘, ‘212‘, ‘从删库到跑路‘);
INSERT INTO `books` VALUES (‘3‘, ‘Linux‘, ‘1231‘, ‘从进门到进牢‘);

基本环境搭建

1.新建Maven项目，ssmbuild，添加web的支持

2.导入相关的pom依赖

   <!--依赖：junit,数据库驱动,连接池,servlet,jsp,mybatis,mybatis-spring,spring-->

        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <version>4.13</version>
        </dependency>
        <!--数据库驱动-->
        <dependency>

            <version>5.3.9</version>
        </dependency>
    </dependencies>

3.Maven资源过滤设置

    <!--静态资源导出问题-->
    <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>

4.建立基本结构和配置框架！

com.yyw.pojo
com.yyw.dao
com.yyw.service
com.yyw.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>
    
</configuration>

applicationContext.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

1.数据库配置文件database.properties

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/ssmbuild?userSSL=true&useUnicode=true&characterEncoding=utf8
jdbc.username=root
jdbc.password=wuhui1017

2.IDEA关联数据库

3.编写MyBatis的核心配置文件

<?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>

    <!--配置数据源，交给Spring去做-->
    <typeAliases>
        <package name="com.yyw.pojo"/>
    </typeAliases>

    <mappers>
        <mapper class="com.yyw.dao.BookMapper"/>
    </mappers>
</configuration>

4.编写实体类com.yyw.pojo.Books,使用lombok插件！

package com.yyw.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;
}

5编写Dao层的Mapper接口！

package com.yyw.dao;

import com.yyw.pojo.Books;
import org.apache.ibatis.annotations.Param;

import java.util.List;

public interface BookMapper {

    //增加
    int addBook(Books books);

    //删除
    int deleteBookById(@Param("bookId") int id);

    //更新
    int updateBook(Books books);


    //查询一本书
    Books queryBookById(@Param("bookId") int id);


    //查询全部
    List<Books> queryAllBook();

    //根据书名查询
    Books queryBookByName(@Param("bookName") String bookName);

}

6.编写对应的Mapper.xml文件，需要导入MyBatis的包

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE mapper
        PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.yyw.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="queryBookByName" resultType="Books">
        select * from ssmbuild.books
        where bookName=#{bookName}
    </select>
</mapper>

7.编写Service层的接口和实现类

接口：

package com.yyw.service;

import com.yyw.pojo.Books;
import org.apache.ibatis.annotations.Param;

import java.util.List;

public interface BookService {

    //增加
    int addBook(Books books);

    //删除
    int deleteBookById(int id);

    //更新
    int updateBook(Books books);


    //查询一本书
    Books queryBookById(int id);


    //查询全部
    List<Books> queryAllBook();

    //根据书名查询
    Books queryBookByName(String bookName);

}

实现类：

package com.yyw.service;

import com.yyw.dao.BookMapper;
import com.yyw.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) {
        System.out.println("BookServiceImpl:addBook=>"+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层

1.配置Spring整合Mybatis，我们这里使用c3p0连接池

2.编写Spring整合MyBatis的相关配置文件spring-dao.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"
       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">

    <!--1.关联数据库配置文件-->
    <context:property-placeholder location="classpath:database.properties"/>

    <!--2.连接池
            dbcp:半自动化操作，不能自动连接
            c3p0:自动化操作，自动加载配置文件，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}"/>

        <!--c3p0连接池的私有属性-->
        <property name="maxPoolSize" value="30"/>
        <property name="minPoolSize" value="10"/>
        <!--关闭连接后不自动commit-->
        <property name="autoCommitOnClose" value="false"/>
        <!--获取连接超时时间-->
        <property name="checkoutTimeout" value="10000"/>
        <!--当获取连接失败重试次数-->
        <property name="acquireRetryAttempts" value="2"/>
    </bean>
    <!--3.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"/>
        <!--扫描Dao包-->
        <property name="basePackage" value="com.yyw.dao"/>
    </bean>

</beans>

3.Spring整合service层

<?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"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xmlns:tx="http://www.springframework.org/schema/tx"
       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
         http://www.springframework.org/schema/aop
         https://www.springframework.org/schema/aop/spring-aop.xsd
          http://www.springframework.org/schema/tx
          http://www.springframework.org/schema/tx/spring-tx.xsd">

    <!--1.扫描service下的包-->
    <context:component-scan base-package="com.yyw.service"/>

    <!--2.将我们的所有业务类，注入到Spring,可以通过配置或者注解实现-->
    <bean id="BookServiceImpl" class="com.yyw.service.BookServiceImpl">
        <property name="bookMapper" ref="bookMapper"/>
    </bean>
    <!--3.声明式事务配置-->
    <!--注入数据源-->
    <bean id="TransactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource"/>
    </bean>


    <!--结合AOP实现事务的织入-->
    <!--配置事务通知-->
    <tx:advice id="txAdvice" transaction-manager="TransactionManager">
        <!--给那些方法配置事务-->
        <!--配置事务的传播特性：new propagation-->
        <tx:attributes>
            <tx:method name="*" propagation="REQUIRED"/>
        </tx:attributes>
    </tx:advice>
    <!--4.aop事务支持-->
    <aop:config>
        <aop:pointcut id="txPointCut" expression="execution(* com.yyw.dao.*.*(..))"/>
        <aop:advisor advice-ref="txAdvice" pointcut-ref="txPointCut"/>
    </aop:config>


</beans>

SpringMVC层

1.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">

    </servlet-mapping>


    <!--乱码过滤-->
    <filter>

    <!--Session-->
    <session-config>
        <session-timeout>15</session-timeout>
    </session-config>
</web-app>

2.spring-mvc.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"

    <!--2.静态资源过滤-->
    <mvc:default-servlet-handler/>

        <property name="prefix" value="/WEB-INF/jsp/"/>
        <property name="suffix" value=".jsp"/>
    </bean>

</beans>

3.Spring配置整合文件，applicationContext.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>

配置文件暂时结束，Controller和视图层编写

1.BookController类编写

package com.yyw.controller;

import com.yyw.pojo.Books;
import com.yyw.service.BookService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

import javax.servlet.http.HttpServletRequest;
import java.util.ArrayList;
import java.util.List;

@Controller
@RequestMapping("/book")
public class BookController {
    //controller调service层
    @Autowired
    @Qualifier("BookServiceImpl")
    private BookService bookService;

    //查询全部书籍，并返回到书籍展示页面
    @RequestMapping("/allBook")
    public String list(Model model){
        List<Books> list = bookService.queryAllBook();
        model.addAttribute("list",list);
        return "allBook";
    }

    //添加书籍
    @RequestMapping("/addBook")
    public String add(){
        return "addBook";
    }

    //添加书籍请求
    @RequestMapping("/addBook1")
    public String addBook(Books books){
        System.out.println("addBook==>"+books);
        bookService.addBook(books);
        return "redirect:/book/allBook";//重定向到allBook
    }

    //删除书籍
    @RequestMapping("/deleteBook/{bookId}")
    public String deleteBook(@PathVariable("bookId") int id){
        bookService.deleteBookById(id);

        return "redirect:/book/allBook";
    }

    //修改书籍
    @RequestMapping("/update")
    public String update(int id,Model model){
        Books books = bookService.queryBookById(id);
        model.addAttribute("QBooks",books);
        return "updateBook";
    }

    //修改书籍详情
    @RequestMapping("/updateBook")
    public String updateBook(Books books){
        System.out.println("updateBooks=>"+books);
        int i = bookService.updateBook(books);

        if (i>0){
            System.out.println("添加books成功"+books);
        }
        return "redirect:/book/allBook";
    }

    //查询书籍
    @RequestMapping("/query")
    public String queryBook(String queryBookName,Model model){

        Books books = bookService.queryBookByName(queryBookName);
        List<Books> list=new ArrayList<Books>();
        list.add(books);

        if (books==null){
            list=bookService.queryAllBook();
            model.addAttribute("error","没有对应信息");
        }


        model.addAttribute("list",list);
        return "allBook";
    }



}
