一、开发环境准备
- JDK1.8
- MySQL8
- idea2021
- Tomcat8.5.87
- Apache-Maven3.9
二、搭建SSM
2.1新建Maven项目
【File】-> 【new Project】-> 【选择Archetype】
2.2项目整体结构
项目的整体结构： 包括resources目录下的xml和webapp目录下文件。如果不包含某些文件，就自己创建。
MVC结构、spring-config.xml（applicationContext.xml）、jdbc.properties（数据源）、mybatis-config.xml（mybatis配置类）、spring-mvc.xml（springMVC前端控制器配置类）、web.xml（web项目配置类）
2.3spring-config.xml配置
<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:jdbc.properties"/><bean id="myDataSource" class="com.alibaba.druid.pool.DruidDataSource" init-method="init" destroy-method="close"><property name="url" value="${database.url}"/><property name="username" value="${database.username}"/><property name="password" value="${database.password}"/>bean><bean id="factory" class="org.mybatis.spring.SqlSessionFactoryBean"><property name="dataSource" ref="myDataSource"/><property name="configLocation" value="classpath:mybatis-config.xml"/>bean><bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"><property name="sqlSessionFactoryBeanName" value="factory"/><property name="basePackage" value="com.shenxm.mapper"/>bean>

2.4jdbc.properties配置
database.driver=com.mysql.cj.jdbc.Driver
database.url=jdbc:mysql://localhost:3306/demo
database.username=root
database.password=123456
2.5mybatis-config.xml配置
DOCTYPE configurationPUBLIC "-//mybatis.org//DTD Config 3.0//EN""http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration><properties resource="jdbc.properties"/><settings><setting name="logImpl" value="STDOUT_LOGGING"/><setting name="autoMappingBehavior" value="PARTIAL"/><setting name="mapUnderscoreToCamelCase" value="true"/><setting name="lazyLoadingEnabled" value="true"/>settings><mappers><package name="com.shenxm.mapper"/>mappers>

2.6spring-mvc.xml配置
<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 https://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/mvc https://www.springframework.org/schema/mvc/spring-mvc.xsd"><mvc:annotation-driven /><context:component-scan base-package="com.shenxm"/>beans>
2.7web.xml配置
<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"><filter><filter-name>CharacterEncodingFilterfilter-name><filter-class>org.springframework.web.filter.CharacterEncodingFilterfilter-class><init-param><param-name>encodingparam-name><param-value>UTF-8param-value>init-param>filter><filter-mapping><filter-name>CharacterEncodingFilterfilter-name><url-pattern>/*url-pattern>filter-mapping><servlet><servlet-name>DispatcherServletservlet-name><servlet-class>org.springframework.web.servlet.DispatcherServletservlet-class><init-param><param-name>contextConfigLocationparam-name><param-value>classpath:spring-mvc.xmlparam-value>init-param><load-on-startup>1load-on-startup>servlet><servlet-mapping><servlet-name>DispatcherServletservlet-name><url-pattern>/url-pattern>servlet-mapping><context-param><param-name>contextConfigLocationparam-name><param-value>classpath:spring-config.xmlparam-value>context-param><listener><listener-class>org.springframework.web.context.ContextLoaderListenerlistener-class>listener>

2.10Java代码
controller层：
package com.shenxm.controller;import com.shenxm.po.Test;
import com.shenxm.service.TestService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;@Controller
@RequestMapping("/test")
public class DemoController {@Autowiredprivate TestService testService;@RequestMapping("/add")public ModelAndView addOneTest(Test test){ModelAndView modelAndView = new ModelAndView();testService.addTest(test);System.out.println("addTest方法执行完成");modelAndView.setViewName("/ok.jsp");return modelAndView;}
}
service层接口类：
package com.shenxm.service;
import com.shenxm.po.Test;public interface TestService {int addTest(Test test);
}
service层实现类：
package com.shenxm.service.impl;import com.shenxm.mapper.TestMapper;
import com.shenxm.po.Test;
import com.shenxm.service.TestService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;@Service
public class TestServiceImpl implements TestService {@Autowiredprivate TestMapper testMapper;@Overridepublic int addTest(Test test) {int row = testMapper.addTest(test);return row;}
}mapper层：
TestMapper.java
package com.shenxm.mapper;
import com.shenxm.po.Test;
import org.springframework.stereotype.Component;@Component
public interface TestMapper {int addTest(Test test);
}
TestMapper.xml
DOCTYPE mapperPUBLIC "-//mybatis.org//DTD Mapper 3.0//EN""http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.shenxm.mapper.TestMapper"><insert id="addTest" parameterType="com.shenxm.po.Test" useGeneratedKeys="true" keyProperty="id">insert into test values (null,#{name},#{age})insert>
mapper>
po包：
package com.shenxm.po;import lombok.AllArgsConstructor;
import lombok.Builder;
import lombok.Data;
import lombok.NoArgsConstructor;@Data
@AllArgsConstructor
@NoArgsConstructor
@Builder
public class Test {/** 自增的id */private Integer id;/** 姓名 */private String name;/** 年龄 */private Integer age;
}
2.11测试
