Mybatis层编写
数据库配置文件 database.properties
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/shagnhai
jdbc.url=jdbc:mysql://localhost:3306/mybatis?useSSL=false&useUnicode=true&characterEncoding=UTF-8&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=false&serverTimezone=UTC
jdbc.username=root
jdbc.password=
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,整合后交给spring去做-->
<!--起别名-->
<settings>
<setting name="logImpl" value="STDOUT_lOGGING"/>
</settings>
<typeAliases>
<package name="com.zwt.pojo"/>
</typeAliases>
<mappers>
<mapper class="com.zwt.dao.BookMapper"/>
</mappers>
</configuration>
编写数据库对应的实体类 com.zwt.pojo.Books
package com.zwt.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;
}
编写Dao层的 Mapper接口!
package com.zwt.dao;
import com.zwt.pojo.Books;
import java.util.List;
public interface BookMapper {
//增加一本书
int addBook(Books books);
//删除一本书
int deleteBookById(int id);
//修改一本书
int updateBook(Books books);
//查找一本书
Books queryBookById(int id);
//查找所有书
List<Books> queryAllBook();
//新增搜索框功能
Books queryBookByName(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 mapper
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.zwt.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>
编写Service层的接口和实现类
接口:
package com.zwt.service;
import com.zwt.pojo.Books;
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);
//修改一本书
int updateBook(Books books);
//查找一本书
Books queryBookById(int id);
//查找所有书
List<Books> queryAllBook();
//新增搜索框功能
Books queryBookByName(String bookName);
}
实现类:
package com.zwt.service;
import com.zwt.dao.BookMapper;
import com.zwt.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.queryBookByName(bookName);
}
}
Spring层
1、配置Spring整合MyBatis,我们这里数据源使用c3p0连接池;
2、编写Spring整合Mybatis的相关的配置文件;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">
<!--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>
<!--4、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="sqlSessionFactory"/>
<!--要扫描的dao包-->
<property name="basePackage" value="com.zwt.dao"/>
</bean>
</beans>
Spring整合service层
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

http://www.springframework.org/schema/tx/spring-tx.xsd
http://www.springframework.org/schema/aop
https://www.springframework.org/schema/aop/spring-aop.xsd">
<!--1、扫描service下的包-->
<context:component-scan base-package="com.zwt.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.zwt.service.BookServiceImpl">
<property name="bookMapper" ref="bookMapper"/>
</bean>
<!--3、声明式事务配置-->
<bean id="transactionManage" 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实现事务的织入-->
<!--配置事务的通知-->
<tx:advice id="txAdvice" transaction-manager="transactionManage">
<!--给哪些方法配置事务-->
<!--配置事务的传播特性-->
<tx:attributes>
<tx:method name="*" propagation="REQUIRED"/>
</tx:attributes>
</tx:advice>
<!--配置事务的切入-->
<aop:config>
<aop:pointcut id="txPointCut" expression="execution(* com.zwt.dao.*.*(..))"/>
<aop:advisor advice-ref="txAdvice" pointcut-ref="txPointCut"/>
</aop:config>
</beans>
Spring就是一个大杂烩,一个容器!
SpringMVC层

Spring配置整合文件,applicationContext.xml

Controller 和 视图层编写
BookController 类编写 , 方法一:查询全部书籍
@Controller
//@RequestMapping("/book")
public class BookController {
//controller调service层
@Autowired
@Qualifier("BookServiceImpl")
private BookService bookService;
//查询全部的书籍,并且返回到一个书籍展示页面
@RequestMapping("/allBook")
public String list(Model model){
List<Books> list = bookService.queryAllBook();
model.addAttribute("list",list);
return "allBook";
}
}
编写首页 index.jsp
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
<title>首页</title>
<style>
a{
text-decoration: none;
color:black;
font-size: 18px;
}
h3{
width: 180px;
height: 38px;
margin: 100px auto;
text-align: center;
line-height: 38px;
background: deepskyblue;
border-radius:5px;
}
</style>
</head>
<body>
<h3>
<a href="${pageContext.request.contextPath}/allBook">点击进入列表页</a>
</h3>
