SpringMVC05——SSM整合
整合SSM
需求：熟练掌握MySQL数据库，Spring，JavaWeb及MyBatis知识，简单的前端知识
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、创建一个Maven项目，添加web支持。
2、导入pom相关依赖

<includes>
<include>**/*.properties</include>
<include>**/*.xml</include>
</includes>
<filtering>false</filtering>
</resource>
</resources>
</build>
3、搭建基本结构和配置框架
基本结构:
- com.pp.pojo
- com.pp.dao(mapper)
- com.pp.service
- com.pp.controller
配置框架: - 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">
</beans>
MyBatis层
1、数据库配置文件db.properties
（这里注意区分自己的MySQL版本，8.0+要在url之后配置时区设置）
jdbc.driver=com.mysql.cj.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/ssmbuild?useSSL=true&useUnicode=true&characterEncoding=utf8&serverTimezone=Asia/Shanghai
jdbc.username=root
jdbc.password=root
2、IDEA关联数据库
（这里注意区分自己的MySQL版本，8.0+要在url之后配置时区设置）
3、编写MyBatis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>
<settings>
<setting name="logImpl" value="STDOUT_LOGGING"/>
</settings>
<typeAliases>
<package name="com.pp.pojo"/>
</typeAliases>
<mappers>
<mapper resource="com/pp/mapper/BookMapper.xml"/>
</mappers>
</configuration>
4、编写数据库对应的实体类
（要用到lombok，偷个懒嘿嘿）
package com.pp.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（Mapper层）接口！
package com.pp.mapper;
import com.pp.pojo.Books;
import org.apache.ibatis.annotations.Param;
import java.util.List;
public interface BookMapper {
//增加一个Book
int addBook(Books book);
//根据id删除一个Book
int deleteBookById(int id);
//更新Book
int updateBook(Books books);
//根据id查询,返回一个Book
Books queryBookById(int id);
//查询全部Book,返回list集合
List<Books> queryAllBook();
//查询
List<Books> queryBookByName(@Param("bookName") String bookName);
}
6、编写接口所对应的Mapper.xml文件
<?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.pp.mapper.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>
<select id="queryBookByName" parameterType="java.lang.String" resultType="Books">
select * from books where bookName like concat('%',#{bookName},'%')
</select>
</mapper>
7、编写Service层的接口and实现类
接口：
package com.pp.service;
import com.pp.pojo.Books;
import java.util.List;
public interface BookService {
//增加一个Book
int addBook(Books book);
//根据id删除一个Book
int deleteBookById(int id);
//更新Book
int updateBook(Books books);
//根据id查询,返回一个Book
Books queryBookById(int id);
//查询全部Book,返回list集合
List<Books> queryAllBook();
List<Books> queryBookByName(String bookName);
}
实现类：
package com.pp.service;
import com.pp.mapper.BookMapper;
import com.pp.pojo.Books;
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 BookMapper getBookMapper() {
return bookMapper;
}
public void setBookMapper(BookMapper bookMapper) {
this.bookMapper = bookMapper;
}
public int addBook(Books book) {
return bookMapper.addBook(book);
}
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 List<Books> queryBookByName(String bookName) {
return (List<Books>) bookMapper.queryBookByName(bookName);
}
}
Spring层
1、配置Spring整合MyBatis，使用c3p0连接池
2、编写Spring整合Mybatis的相关配置文件：Spring-mapper.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">
<!-- 配置整合mybatis -->
<!-- 1.关联数据库文件 -->
<context:property-placeholder location="classpath:db.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-config.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.pp.mapper"/>
</bean>
</beans>
3、Spring整合Service层，在Spring-Service.xml中编写
<?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
http://www.springframework.org/schema/context/spring-context.xsd
http://www.springframework.org/schema/aop
http://www.springframework.org/schema/aop/spring-aop.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx.xsd">
<!-- 扫描service相关的bean -->
<context:component-scan base-package="com.pp.service"/>
<!--BookServiceImpl注入到IOC容器中-->
<bean id="BookServiceImpl" class="com.pp.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>
<!-- aop事务支持-->
<!-- 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>
<aop:config>
<!-- 切入点-->
<aop:pointcut id="txPointCut" expression="execution(* com.pp.mapper.*.*(..))"/>
<aop:advisor advice-ref="txAdvice" pointcut-ref="txPointCut"/>
</aop:config>
</beans>
SpringMVC层
这里首先要确保自己的项目是个web项目，如果不是，请添加为web项目！
1、配置web.xml文件
<?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">
<!-- 首先引用DispatcherServlet-->
<servlet>
<servlet-name>DispatcherServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<!-- 关联配置文件！！一定搞清楚，这里关联的是总的配置文件！！！-->
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</init-param>
<!-- 设置加载顺序为1-->
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>DispatcherServlet</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
<!-- 解决乱码的问题，springmvc自带的乱码处理器-->
<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>
<!--Session过期时间 => 这里设置为15min-->
<session-config>
<session-timeout>15</session-timeout>
</session-config>
</web-app>
2、编写Spring-mvc.xml
步骤：
- 扫描web相关的bean：
<context:component-scan base-package="com.pp.controller"/>
- 开启SpringMVC注解驱动：
<mvc:annotation-driven/>
- 静态资源默认servlet配置：
<mvc:default-servlet-handler/>
- 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>
<?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:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd
http://www.springframework.org/schema/mvc
https://www.springframework.org/schema/mvc/spring-mvc.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.pp.controller"/>
</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="spring-dao.xml"/>
<import resource="spring-service.xml"/>
<import resource="spring-mvc.xml"/>
</beans>
Controller和视图层编写
package com.pp.controller;
import com.pp.pojo.Books;
import com.pp.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 java.util.ArrayList;
import java.util.List;
@Controller
@RequestMapping("/book")
public class BookController {
//controller 调service
@Autowired
@Qualifier("BookServiceImpl")
private BookService bookService;
@RequestMapping("/allBook")
//1.查询全部的书籍，并且返回到一个书籍展示页面
public String list(Model model){
List<Books> books = bookService.queryAllBook();
model.addAttribute("books",books);
return "allBook";
}
//跳转到增加书籍页面
@RequestMapping("/toAddBook")
public String toAddPaper(){
return "addBook";
}
//添加书籍的请求
@RequestMapping("/addBook")
public String addBook(Books books){
System.out.println("addBook=>" + books);
bookService.addBook(books);
return "redirect:/book/allBook";//重定向@RequestMapping("/addBook")
}
@RequestMapping("/toUpdate")
public String toUpdatePaper(int id,Model model){
Books books = bookService.queryBookById(id);
model.addAttribute("QBook",books);
return "updateBook";
}
//修改书籍
@RequestMapping("/updateBook")
public String updateBook(Books books){
System.out.println("updateBook=>" + books);
bookService.updateBook(books);
return "redirect:/book/allBook";//重定向@RequestMapping("/addBook")
}
//删除书籍
@RequestMapping("/deleteBook/{bookID}")
public String deleteBook(@PathVariable("bookID") int id){
bookService.deleteBookById(id);
return "redirect:/book/allBook";//重定向@RequestMapping("/addBook")
}
//查询书籍
@RequestMapping("/queryBook")
public String queryBook(String queryBookName,Model model){
List<Books> books = bookService.queryBookByName(queryBookName);
//Books books = (Books) bookService.queryBookByName(queryBookName);
//List<Books> list = new ArrayList<Books>();
//list.add(books);
int size = books.size();
System.err.println("size=>" + size);
if(queryBookName.equals("")){
books = bookService.queryAllBook();
model.addAttribute("error","未查询到");
}
model.addAttribute("books",books);
return "allBook";
}
}
