整合SSM框架

环境要求

环境:

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

  1. 新建一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-spring,spring-->
        <dependencies>
            <!--Junit-->
            <dependency>

            </dependency>
        </dependencies>
       
    
  3. 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>
    
  4. 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

  1. 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
    
  2. 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 + '\'' +
                    '}';
        }
    }
    
  3. 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);
    }
    
  4. 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>
    
  5. 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);
    }
    
    
  6. 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

  1. 配置Spring整合MyBatis,我们这里数据源使用c3p0连接池;

  2. 我们去编写Spring整合Mybatis的相关的配置文件;

    Spring整合dao操作

    <?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}"/>
    
            <!--c3p0连接池的私有属性-->
            <property name="maxPoolSize" value="30"/>
            <property name="minPoolSize" value="10"/>
            <!--关闭连接池后不自动启动commit-->
            <property name="autoCommitOnClose" value="false"/>
            <!--获取连接超时时间-->
            <property name="checkoutTimeout" value="10000"/>
            <!--当获得连接失败重试次数-->
            <property name="acquireRetryAttempts" value="2"/>
         </bean>
    
        <!--3.sqlSessionFactory-->
        <bean id="sqlSessionFactroy" 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,动态的实现了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="sqlSessionFactroy"/>
            <!--要扫描额包-->
            <property name="basePackage" value="com.sheng.dao"/>
        </bean>
    
    </beans>
    
  3. Spring整合service操作

    <?xml version="1.0" encoding="UTF-8"?>
    <beans xmlns="http://www.springframework.org/schema/beans"
           xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

        <!--扫描service下的包-->
        <context:component-scan base-package="com.sheng.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.sheng.service.BookServiceImpl">
            <property name="bookMapper" ref="bookMapper"/>
        </bean>
    
        <!--3.声明式事务配置-->
        <bean id="TransactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
            <!--注入数据源-->
            <property name="dataSource" ref="dataSource"/>
        </bean>
    
        <!--4. AOP事务支持-->
    
        <!--结合AOP实现事务的植入-->
        <!--配置事务通纸-->
        <tx:advice id="txAdvice" transaction-manager="TransactionManager">

            <aop:advisor advice-ref="txAdvice" pointcut-ref="txPointCut"/>
        </aop:config>
    
    
    </beans>
    
  4. Spring整合mvc操作

    <?xml version="1.0" encoding="UTF-8" ?>
    <beans xmlns="http://www.springframework.org/schema/beans"
           xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

          https://www.springframework.org/schema/mvc/spring-mvc.xsd">
    
        <!--1.注解驱动-->
        <mvc:annotation-driven/>
