前言

根据自己的环境参考狂神的视频进行了SSM框架整合,用于备忘

SSM框架整合步骤

1. 创建数据库

在这里插入图片描述

2. IDEA创建maven项目.在pom.xml中设设置java conpiler版本(jdk13)

在这里插入图片描述

3. 导入依赖 jnuit 数据库驱动 数据库连接 Severlet JSp

4. maven 资源过滤

        </dependency>
    </dependencies>

</project>

5. 创建两个项目的目录结构以及Spring 和 Mybatis的配置文件

<?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">

</beans>

<?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>

Mybatis

6. 配置数据库属性

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/ssmbuild?useSSL=false&useUnicode=true&characterEncoding=UTF-8&serverTimezone=UTC
jdbc.username=root
jdbc.password=root

7. 创建Book实体类(使用lombok插件),编写Dao层mapper接口,在mybatis配置中注册mapper

package com.projectname.pojo;

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;

@Data
@AllArgsConstructor
@NoArgsConstructor
public class Book {
    
    
    private int bookID;
    private String bookName;
    private int bookCounts;
    private String detail;

}

package com.projectname.dao;

import com.projectname.pojo.Book;

import java.util.List;

public interface DaoBook {
    
    
    //增加一个Book
    int addBook(Book book);

    //根据id删除一个Book
    int deleteBookById(int id);

    //更新Book
    int updateBook(Book books);

    //根据id查询,返回一个Book
    Book queryBookById(int id);

    //查询全部Book,返回list集合
    List<Book> queryAllBook();
}

<?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.kuang.dao.BookMapper">

    <!--增加一个Book-->
    <insert id="addBook" parameterType="Books">
      insert into ssmbuild.books(bookName,bookCounts,detail)
      values (#{bookName}, #{bookCounts}, #{detail})
   </insert>

    <!--根据id删除一个Book-->
    <delete id="deleteBookById" parameterType="int">
      delete from ssmbuild.books where bookID=#{bookID}
   </delete>

    <!--更新Book-->
    <update id="updateBook" parameterType="Books">
      update ssmbuild.books
      set bookName = #{bookName},bookCounts = #{bookCounts},detail = #{detail}
      where bookID = #{bookID}
   </update>

    <!--根据id查询,返回一个Book-->
    <select id="queryBookById" resultType="Books">
      select * from ssmbuild.books
      where bookID = #{bookID}
   </select>

    <!--查询全部Book-->
    <select id="queryAllBook" resultType="Books">
      SELECT * from ssmbuild.books
   </select>

</mapper>

<?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>
<mappers>
<mapper resource="com/projectname/dao/BookMapper.xml"/>
</mappers>
</configuration>

8. 编写service层的接口和实现类代码

package com.projectname.service;

import com.projectname.pojo.Book;

import java.util.List;

public interface BookService {
    
    
    //增加一个Book
    int addBook(Book book);
    //根据id删除一个Book
    int deleteBookById(int id);
    //更新Book
    int updateBook(Book books);
    //根据id查询,返回一个Book
    Book queryBookById(int id);
    //查询全部Book,返回list集合
    List<Book> queryAllBook();
}

package com.projectname.service;

import com.projectname.dao.BookMapper;
import com.projectname.pojo.Book;

import java.util.List;

public class BookServiceImpl implements BookService {
    
    

    //调用dao层的操作，设置一个set接口，方便Spring管理
    private BookMapper bookMapper;

    public void setBookMapper(BookMapper bookMapper) {
    
    
        this.bookMapper = bookMapper;
    }

    public int addBook(Book book) {
    
    
        return bookMapper.addBook(book);
    }

    public int deleteBookById(int id) {
    
    
        return bookMapper.deleteBookById(id);
    }

    public int updateBook(Book books) {
    
    
        return bookMapper.updateBook(books);
    }

    public Book queryBookById(int id) {
    
    
        return bookMapper.queryBookById(id);
    }

    public List<Book> queryAllBook() {
    
    
        return bookMapper.queryAllBook();
    }
}

Spring

9. 使用Spring编写Mybatis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">
    <context:property-placeholder location="classpath:database.properties"/>
    <!-- 2.数据库连接池 -->
    <!--数据库连接池
        dbcp 半自动化操作 不能自动连接
        c3p0 自动化操作（自动的加载配置文件 并且设置到对象里面）
    -->
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <!-- 配置连接池属性 -->
        <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.配置SqlSessionFactory对象 -->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <!-- 注入数据库连接池 -->
        <property name="dataSource" ref="dataSource"/>
        <!-- 配置MyBaties全局配置文件:mybatis-config.xml -->
        <property name="configLocation" value="classpath:mybatis-configuration.xml"/>
    </bean>
    <!-- 4.配置扫描Dao接口包，动态实现Dao接口注入到spring容器中 -->
    <!--解释 ：https://www.cnblogs.com/jpfss/p/7799806.html-->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <!-- 注入sqlSessionFactory -->
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
        <!-- 给出需要扫描Dao接口包 -->
        <property name="basePackage" value="com.projectname.dao"/>
    </bean>
</beans>

10. Spring 整合service层 spring-service

<?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相关的bean -->
    <context:component-scan base-package="com.projectname.service" />

    <!--BookServiceImpl注入到IOC容器中-->
    <bean id="BookServiceImpl" class="com.projectname.service.BookServiceImpl">
        <property name="bookMapper" ref="bookMapper"/>
    </bean>

    <!-- 配置事务管理器 -->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <!-- 注入数据库连接池 -->
        <property name="dataSource" ref="dataSource" />
    </bean>

</beans>

Spring MVC层

11. configuate the 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"> <!-- 配置SpringMVC -->
    <!-- 1.开启SpringMVC注解驱动 -->
    <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-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>

12. 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" xmlns:mvc="http://www.springframework.org/schema/mvc"
       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/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">
    <!-- 配置SpringMVC -->
    <!-- 1.开启SpringMVC注解驱动 -->
    <mvc:annotation-driven />
    <!-- 2.静态资源默认servlet配置-->
    <mvc:default-servlet-handler/>

    <!-- 3.配置jsp 显示ViewResolver视图解析器 -->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="viewClass" value="org.springframework.web.servlet.view.JstlView" />
        <property name="prefix" value="/WEB-INF/jsp/" />
        <property name="suffix" value=".jsp" />
    </bean>
    <!-- 4.扫描web相关的bean -->
    <context:component-scan base-package="com.projectname.controller" />
</beans>

13. configuate 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" xmlns:mvc="http://www.springframework.org/schema/mvc"
    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/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">

 <import resource="spring-dao.xml"/>
 <import resource="spring-service.xml"/>
 <import resource="spring-mvc.xml"/>

</beans>

一些杂七杂八的配置

14. 添加日志功能
