SSM项目案例搭建整合含源码（IDEA版）轻松上手
环境：
ssm项目源码 点我下载 ！！！！免费下载不要money
- IDEA
- MySql5.7以上
- Tomcat7.0以上
- Maven3.0以上
运用Spring MyBatis,mysql 简单前端知识总结来说，配置地狱，各种配置，恶心到吐，还是springboot香，但是总要有个过程吧，难受完了，你会看到新的曙光
1.简洁的运行截图，花里胡哨可以自己加，基础的增删改查CRUD工程师
2.数据库建表，我这里是navicat
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, '华为手册', 30, '博学的利郎');
(2, '中东局势', 10, '如何生存');
(3, '上下五千年', 5, '我要当秦始皇');
(4, '美国是狗', 999999, '不用解释');
3.导入依赖（建议保存，通用依赖）
<dependencies>
<!--Junit-->
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>

4.Maven资源过滤设置 静态资源导出设置
<build>
<resources>
<resource>
<directory>src/main/java</directory>
<includes>
<include>**/*.properties
**/ *.xml</include>
</includes>
<filtering>false</filtering>
</resource>
<resource>
<directory>src/main/resources</directory>
<includes>
<include>**/*.properties
**/ *.xml</include>
</includes>
<filtering>false</filtering>
</resource>
</resources>
</build>
5.看一下这是整体的架构结构
6.首先完成数据库的配置：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>
<!--配置实体别名-->
<typeAliases>
<package name="com.learn.pojo"/>
</typeAliases>
<mappers>
<package name="com.learn.dao"/>
</mappers>
</configuration>
7.MyBatis层（你的mysql用户名和密码与之对应）：database.properties
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/ssmbuild?useSSL=true&useUnicode=true&characterEncoding=utf8
jdbc.username=root
jdbc.password=123456
8.MyBatis的核心配置类 ：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>
<!--配置实体别名-->
<typeAliases>
<package name="com.learn.pojo"/>
</typeAliases>
<mappers>
<package name="com.learn.dao"/>
</mappers>
</configuration>
9.在pojo包下写实体类（与数据库要与之对应）：Books
package com.learn.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;
}
10.编写：BooksMapper
package com.learn.dao;
import com.learn.pojo.Books;
import java.util.List;
public interface BooksMapper {
int addBook(Books books);
int deleteBook(int bookId);
int updateBook(Books books);
Books getBookById(int bookId);
List<Books> findAll();
}
11.写SQL语句：BooksMapper.xml
<?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.learn.dao.BooksMapper">
<insert id="addBook" parameterType="Books">
insert into books (bookName,bookCounts,detail) values (#{bookName},#{bookCounts},#{detail})
</insert>
<delete id="deleteBook" parameterType="int">
delete from books where bookID=#{bookID}
</delete>
<update id="updateBook" parameterType="Books">
update books set bookName=#{bookName},bookCounts=#{bookCounts},detail=#{detail} where bookID=#{bookID}
</update>
<select id="getBookById" parameterType="int" resultType="Books">
select *
from books where bookID=#{bookID};
</select>
<select id="findAll" resultType="Books" >
select *
from books;
</select>
</mapper>
12.现在可以写与之对应的（这里写死就可以保存，没有逻辑结构）：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
http://www.springframework.org/schema/context/spring-context.xsd">
<!--引入数据库配置文件-->
<context:property-placeholder location="classpath:database.properties"/>
<!--根据数据库连接信息创建连接池-->
<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>
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource"/>
<!--mybatis的客户化配置-->
<property name="configLocation" value="classpath:mybatis-config.xml"/>
</bean>
<!--使用整合包生产代理对象注入到spring容器中-->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
<property name="basePackage" value="com.learn.dao"/>
</bean>
</beans>
13.接下来是编写服务层：BooksServiceImpl
package com.learn.service.impl;
import com.learn.dao.BooksMapper;
import com.learn.pojo.Books;
import com.learn.service.BooksService;
import java.util.List;
public class BooksServiceImpl implements BooksService {
private BooksMapper booksMapper;
public void setBooksMapper(BooksMapper booksMapper) {
this.booksMapper = booksMapper;
}
public int addBook(Books books) {
return booksMapper.addBook(books);
}
public int deleteBook(int bookId) {
int i= booksMapper.deleteBook(bookId);
int j=1/0;
return i;
}
public int updateBook(Books books) {
return booksMapper.updateBook(books);
}
public Books getBookById(int bookId) {
return booksMapper.getBookById(bookId) ;
}
public List<Books> findAll() {
return booksMapper.findAll();
}
}
14.与之对应的BooksService
package com.learn.service;
import com.learn.pojo.Books;
import java.util.List;
public interface BooksService {
int addBook(Books books);
int deleteBook(int bookId);
int updateBook(Books books);
Books getBookById(int bookId);
List<Books> findAll();
}
15.剩余最后两个配置类了：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"

http://www.springframework.org/schema/aop
https://www.springframework.org/schema/aop/spring-aop.xsd
http://www.springframework.org/schema/tx
https://www.springframework.org/schema/tx/spring-tx.xsd">
<context:component-scan base-package="com.learn.service"/>
<bean id="booksService" class="com.learn.service.impl.BooksServiceImpl">
<property name="booksMapper" ref="booksMapper"/>
</bean>
<!--开启声明式事务管理器-->
<bean id="dataSourceTransactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource"/>
</bean>
<!--定义事务管理器的作用范围-->
<tx:advice id="txAdvice" transaction-manager="dataSourceTransactionManager">
<tx:attributes>
<tx:method name="*" propagation="REQUIRED"/>
</tx:attributes>
</tx:advice>
<!--定义在哪些方法上需要使用事务管理器-->
<aop:config>
<aop:pointcut id="txPoint" expression="execution(* com.learn.*.*.*(..))"/>
<aop:advisor advice-ref="txAdvice" pointcut-ref="txPoint"/>
</aop:config>
</beans>
16.spring-webMvc.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"
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">
<!--注解驱动-->
<mvc:annotation-driven/>
<!--不处理静态资源-->
<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.learn.controller" />
</beans>
17.最最关键的：BookController层！！！！！增删改查的操作都在里面
package com.learn.controller;
import com.learn.pojo.Books;
import com.learn.service.BooksService;
import org.springframework.beans.factory.annotation.Autowired;
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 javax.servlet.http.HttpServletRequest;
import java.util.List;
@Controller
@RequestMapping("/book")
public class BookController {
@Autowired
private BooksService booksService;
@RequestMapping("/queryAll")
public String getAllBooks(Model model){
List<Books> books = booksService.findAll();
model.addAttribute("bookList",books);
return "AllBook";
}
@RequestMapping("/toAddBook")
public String toAddBookPage(){
return "addBook";
}
@RequestMapping("/addBook")
public String addBook(Books book , HttpServletRequest request){
//表单提交的name与实体类属性一致springmvc会封装到对象中，不一致需要从request中去取
System.out.println(request.getParameter("detail"));
booksService.addBook(book);
return "redirect:/book/queryAll";
}
//restful风格参数获取
@RequestMapping("/del/{bookId}")
public String delBook(@PathVariable int bookId){
booksService.deleteBook(bookId);
return "redirect:/book/queryAll";
}
//用问号传参的字段名和参数名一致可以直接接收
@RequestMapping("/toUpdateBook")
public String toUpdateBook(Model model,int id){
Books book = booksService.getBookById(id);
model.addAttribute("book",book);
return "updateBook";
}
@RequestMapping("/updateBook")
public String updateBook(Books book){
booksService.updateBook(book);
return "redirect:/book/queryAll";
}
}
