ssm整合详细Mybatis Spring SpringMVC详细步骤
一、环境介绍和数据库搭建
1.环境要求
- IDEA
- MySQL5.7.19
- Tomcat 9
- Maven 3.6
要求:
- 要熟练掌握MySQL数据库、Spring、JavaWeb及MyBatis知识,简单的前端知识;
2.数据库环境
在ssmbuild数据库创建存放书籍数据的数据库表
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');
二、基本环境搭建
1.新建普通的maven项目
2.导入pom依赖
<!--依赖:junit,数据库驱动,连接池,servlet,jsp,mybatis,mybatis-spring,spring-->
<dependencies>
<!--junit-->
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.12</version>
</dependency>
<!--数据库驱动-->
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.1.47</version>
</dependency>
<!--数据库连接池:c3p0:dbcp-->
<dependency>
<groupId>com.mchange</groupId>
<artifactId>c3p0</artifactId>
<version>0.9.5.2</version>
</dependency>
<!--servlet jsp-->
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>servlet-api</artifactId>
<version>2.5</version>
</dependency>
<dependency>
<groupId>javax.servlet.jsp</groupId>
<artifactId>jsp-api</artifactId>
<version>2.2</version>
</dependency>
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>jstl</artifactId>
<version>1.2</version>
</dependency>
<!--Mybatis-->
<dependency>
<groupId>org.mybatis</groupId>
<artifactId>mybatis</artifactId>
<version>3.5.2</version>
</dependency>
<dependency>
<groupId>org.mybatis</groupId>
<artifactId>mybatis-spring</artifactId>
<version>2.0.2</version>
</dependency>
<!--spring-->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
<version>5.1.9.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-jdbc</artifactId>
<version>5.1.9.RELEASE</version>
</dependency>
<dependency>
<groupId>org.projectlombok</groupId>
<artifactId>lombok</artifactId>
<version>1.18.10</version>
</dependency>
<dependency>
<groupId>org.aspectj</groupId>
<artifactId>aspectjweaver</artifactId>
<version>1.8.13</version>
</dependency>
</dependencies>
3.Maven资源过滤设置
<!--静态资源导出问题-->
<!--在build中配置resources,来防止我们资源导出失败的问题-->
<build>
<resources>
<resource>
<directory>src/main/resources</directory>
<includes>
<include>**/*.properties</include>
<include>**/*.xml</include>
</includes>
<filtering>true</filtering>
</resource>
<resource>
<directory>src/main/java</directory>
<includes>
<include>**/*.properties</include>
<include>**/*.xml</include>
</includes>
<filtering>true</filtering>
</resource>
</resources>
</build>
4.连接数据库(连接好的样子如下图)
5.搭建项目目录结构
com.kuang目录下
- pojo
- dao
- service
- controller
resources目录下
- mybatis-config.xml mybatis核心配置文件
- applicationContext.xml spring核心配置文件
项目所需的基本环境已经搭建好了
三、整合Mybatis层
1.数据库配置文件 database.properties
jdbc.driver=com.mysql.jdbc.Driver
# 如果使用mysql8.0还要增加一个时区设置
jdbc.url=jdbc:mysql://localhost:3306/ssmbuild?useSSL=false&useUnicode=true&characterEncoding=UTF-8
jdbc.username=root
jdbc.password=root
Mysql8.0的时区设置
- 百度搜索 “MYSQL8.0url链接时区设置” 附上链接
- serverTimezone 设置加上 serverTimezone=Asia/Shanghai
jdbc.url=jdbc:mysql://localhost:3306/ssmbuild?useSSL=false&useUnicode=true&characterEncoding=UTF-8&serverTimezone=Asia/Shanghai
2.编写MyBatis的核心配置文件 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>
<!--配置数据源,交给Spring去做-->
<!--别名-->
<typeAliases>
<package name="com.kuang.pojo"/>
</typeAliases>
</configuration>
3.编写数据库对应的实体类
使用lombok插件
pojo 文件夹下的 Books.java
package com.kuang.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;
}
4.编写Dao层的mapper接口 BookMapper
package com.kuang.dao;
import com.kuang.pojo.Books;
import org.apache.ibatis.annotations.Param;
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();
}
5.编写接口对应的 Mapper.xml 文件
<?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.kuang.dao.BookMapper">
<!--添加书籍-->
<insert id="addBook" parameterType="Books">
insert into books(bookName,bookCounts,detail) values (#{bookName},#{bookCounts},#{detail})
</insert>
<!--通过书籍ID删除书籍-->
<delete id="deleteBookById" parameterType="int">
delete from books where bookID=#{bookId}
</delete>
<!--修改书籍信息-->
<update id="updateBook" parameterType="Books">
update books
set bookName=#{bookName},bookCounts=#{bookCounts},detail=#{detail}
where bookID=#{bookID}
</update>
<!--通过书籍ID查询书籍-->
<select id="queryBookById" resultType="Books">
select * from books
where bookID=#{bookId}
</select>
<!--查询所有书籍-->
<select id="queryAllBook" resultType="Books">
select * from books
</select>
</mapper>
**将mapper.xml注册进MyBatis核心配置文件 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>
<!--配置数据源,交给Spring去做-->
<!--别名-->
<typeAliases>
<package name="com.kuang.pojo"/>
</typeAliases>
<mappers>
<mapper class="com.kuang.dao.BookMapper"/>
</mappers>
</configuration>
6.编写Service层的接口和实现类
BookService接口
package com.kuang.service;
import com.kuang.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);
//查询一本书
Books queryBookById(int id);
//查询所有书
List<Books> queryAllBook();
}
BookService实现类
package com.kuang.service;
import com.kuang.dao.BookMapper;
import com.kuang.pojo.Books;
import java.util.List;
public class BookServiceImpl implements BookService {
//service调dao层 组合dao层
private BookMapper bookMapper;
public void setBookMapper(BookMapper bookMapper) {
this.bookMapper = bookMapper;
}
//增加书籍
public int addBook(Books books) {
return bookMapper.addBook(books);
}
//通过书籍ID删除
public int deleteBookById(int id) {
return bookMapper.deleteBookById(id);
}
//修改书籍
public int updateBook(Books books) {
return bookMapper.updateBook(books);
}
//通过书籍id查询书籍
public Books queryBookById(int id) {
return bookMapper.queryBookById(id);
}
//查询所有书籍
public List<Books> queryAllBook() {
return bookMapper.queryAllBook();
}
}
四、整合Spring层
1.Spring整合dao层 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
https://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 需要手动连接
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-->
<!--最大连接池数量-->
<property name="maxPoolSize" value="30"/>
<!--最小连接池数量-->
<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"/>
<!--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.laohan.dao"/>
</bean>
</beans>
2.Spring整合service层 spring-service.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
https://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context https://www.springframework.org/schema/context/spring-context.xsd">
<!--1.扫描service下的包-->
<context:component-scan base-package="com.laohan.service"/>
<!--2.将我们所有的业务类注入到Spring,可以通过配置,或者注解实现-->
<bean id="BookServiceImpl" class="com.laohan.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!-->
<tx:advice id="txAdvice" transaction-manager="transactionManager">
<tx:attributes>
<tx:method name="*" propagation="REQUIRED"/>
</tx:attributes>
</tx:advice>
<aop:config>
<aop:pointcut id="txPointCut" expression="execution(* com.shu.dao.*.*(..))"/>
<aop:advisor advice-ref="txAdvice" pointcut-ref="txPointCut"/>
</aop:config>
</beans>
把dao和service连到一起 applicationContenxt.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
https://www.springframework.org/schema/beans/spring-beans.xsd">
<import resource="classpath:spring-dao.xml"/>
<import resource="classpath:spring-service.xml"/>
</beans>
五、整合SpringMVC层
1.增加web支持
右键项目,点击 Add Framework Support
选中,默认4.0 点击ok即可
成功之后这里会有蓝点
2.配置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">
<!--1.dispatchServlet-->
<servlet>
<servlet-name>springmvc</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring-mvc.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>springmvc</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
<!--2.乱码过滤-->
<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>
<!--3.Session过期时间-->
<session-config>
<session-timeout>15</session-timeout>
</session-config>
</web-app>
3.配置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
https://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">
<!--1.注解驱动-->
<mvc:annotation-driven/>
<!--2.静态资源过滤-->
<mvc:default-servlet-handler/>
<!--3.扫描包:controller-->
<context:component-scan base-package="com.laohan.controller"/>
<!--4.视图解析器-->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/jsp/"/>
<property name="suffix" value=".jsp"/>
</bean>
</beans>
加入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
https://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>
六、查询书籍功能
1.先写controller
BookController.java
package com.laohan.controller;
import com.laohan.pojo.Books;
import com.laohan.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 层
@Autowired
@Qualifier("BookServiceImpl")
private BookService bookService;
//查询全部的书籍,并且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";
}
//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";//重定向到请求了
}
//跳转到修改页面
@RequestMapping("/toUpdateBook")
public String toUpdatePaper(int id,Model model){
Books books = bookService.queryBookById(id);
model.addAttribute("books",books);
return "updateBook";
}
//修改书籍
@RequestMapping("/updateBook")
public String updateBook(Books books,Model model){
System.out.println("updateBook=>"+books);
int i = bookService.updateBook(books);
if(i>0){
System.out.println("修改书籍成功:"+books);
}
return "redirect:/book/allBook";//重定向
}
//删除书籍
@RequestMapping("/deleteBook/{bookID}")
public String deleteBook(@PathVariable("bookID") int id){
bookService.deleteBookById(id);
return "redirect:/book/allBook";//重定向
}
//查询书籍
@RequestMapping("/queryBook")
public String queryBook(String queryBookName,Model model){
Books books = bookService.queryBookByName(queryBookName);
System.err.println("Controller-queryBook=>books : "+books);
List<Books> list = new ArrayList<Books>();
list.add(books);
if(books==null){
list = bookService.queryAllBook();
model.addAttribute("error","未查到");
}
System.err.println("Controller-queryBook=>list : "+list);
model.addAttribute("list",list);
return "allBook";
}
}
初测试的时候报了个错 找不到BookServiceImpl
改web.xml
原来引用的springmvc.xml 改成 applicationContext.xml
<!--1.dispatchServlet-->
<servlet>
<servlet-name>springmvc</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>springmvc</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
2.写对应allbook页面
allBook.jsp
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
