矫情吗；* 2022-03-26 05:49 358阅读 0赞

### 开发环境 ###

*  开发工具：Eclipse + STS插件
 *  JDK版本：9.0.4
 *  MySQL版本：8.0.12
 *  Spring Boot版本：2.1.2

### 1、创建Spring Boot工程 ###

####  （1）工程创建过程 ####

####  （2）工程目录结构 ####

注：工程创建完成后，缺少的文件夹需手动补全。

####  （3）添加额外依赖工程 ####

所依赖的jar包和插件由工程创建过程中所选的组件自动生成。由于本工程需要用到JSP视图，需要在pom.xml中手动添加额外依赖：

<dependency>
    	<groupId>org.apache.tomcat.embed</groupId>
    	<artifactId>tomcat-embed-jasper</artifactId>
    </dependency>
    
    <dependency>
    	<groupId>javax.servlet</groupId>
    	<artifactId>jstl</artifactId>
    </dependency>

####  （4）配置application.yml文件 ####

注：Spring Boot工程默认的配置文件为application.properties，可选中配置文件，单击鼠标右键，选中Convert .properties to .yaml后，转为application.yml文件。

##### application.yml： #####

#服务器配置
    server:
      port: 8090
    #spring配置
    spring:
      #数据源配置(默认数据源为HikariDataSource)
      datasource:
        #配置mysql数据库
        driver-class-name: com.mysql.cj.jdbc.Driver
        url: jdbc:mysql://localhost/customer_manager?serverTimezone=CTT
        username: root
        password: 1314
      #配置JSP视图
      mvc:
        view:
          prefix: /WEB-INF/jsp/
          suffix: .jsp
    #配置mybatis框架
    mybatis:
      #定义Mapper接口映射文件位置 
      mapper-locations: classpath:mapper/*.xml
      #定义实体类位置
      type-aliases-package: com.ming.ssm.pojo
    #控制台打印sql语句
    logging:
      level:
        com.ming.ssm.mapper: debug

### 2、持久层实现 ###

##### customer\_manager数据库中customer表的构建： #####

![20190105125330763.jpg][]

##### Customer： #####

package com.ming.ssm.pojo;
    import java.io.Serializable;
    /** * 数据库(customer_manager)中表(customer)所对应的实体类(Customer) * @author Mr.F * */
    public class Customer implements Serializable{ 
    	private static final long serialVersionUID = 1L;
    	private Long c_id;
    	private String c_name;
    	private String c_password;
    	private String c_address;
    	private String c_phone;
    	private String c_email;
    	public Long getC_id() { 
    		return c_id;
    	}
    	public void setC_id(Long c_id) { 
    		this.c_id = c_id;
    	}
    	public String getC_name() { 
    		return c_name;
    	}
    	public void setC_name(String c_name) { 
    		this.c_name = c_name;
    	}
    	public String getC_password() { 
    		return c_password;
    	}
    	public void setC_password(String c_password) { 
    		this.c_password = c_password;
    	}
    	public String getC_address() { 
    		return c_address;
    	}
    	public void setC_address(String c_address) { 
    		this.c_address = c_address;
    	}
    	public String getC_phone() { 
    		return c_phone;
    	}
    	public void setC_phone(String c_phone) { 
    		this.c_phone = c_phone;
    	}
    	public String getC_email() { 
    		return c_email;
    	}
    	public void setC_email(String c_email) { 
    		this.c_email = c_email;
    	}
    }

##### CustomerMapper： #####

package com.ming.ssm.mapper;
    import java.util.List;
    import org.apache.ibatis.annotations.Mapper;
    import com.ming.ssm.pojo.Customer;
    /** * 持久层实现Mybatis框架中的Mapper接口，声名对数据库的操作方法 * @author Mr.F * */
    @Mapper
    public interface CustomerMapper { 
    	List<Customer> findAllCustomer(); //查询所有客户信息
    }

##### CustomerMapper.xml： #####

<?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.ming.ssm.mapper.CustomerMapper">
    	
    	<select id="findAllCustomer" resultType="Customer">
    		SELECT * FROM `customer`
    	</select>
    </mapper>

### 3、业务层实现 ###

#### CustomerService： ####

package com.ming.ssm.service;
    import java.util.List;
    import com.ming.ssm.pojo.Customer;
    /** * 定义业务层接口 * @author Mr.F * */
    public interface CustomerService { 
    	List<Customer> findAllCustomer(); //查询所有客户信息
    }

#### CustomerServiceImpl： ####

package com.ming.ssm.service.impl;
    import java.util.List;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.stereotype.Service;
    import com.ming.ssm.mapper.CustomerMapper;
    import com.ming.ssm.pojo.Customer;
    import com.ming.ssm.service.CustomerService;
    /** * 实现业务层的CustomerService接口 * @author Mr.F * */
    @Service
    public class CustomerServiceImpl implements CustomerService{ 	
    	@Autowired
    	private CustomerMapper customerMapper;	
    	@Override
    	public List<Customer> findAllCustomer() { 		
    		return customerMapper.findAllCustomer();
    	}	
    }

### 4、控制层实现 ###

##### CustomerController： #####

package com.ming.ssm.controller;
    import java.util.List;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.stereotype.Controller;
    import org.springframework.ui.Model;
    import org.springframework.web.bind.annotation.RequestMapping;
    import com.ming.ssm.pojo.Customer;
    import com.ming.ssm.service.CustomerService;
    /** * 定义控制层类 * @author Mr.F * */
    @Controller
    public class CustomerController { 	
    	@Autowired
    	private CustomerService customerService;	
    	@RequestMapping("findAll")
    	public String findAll(Model model) { 		
    		List<Customer> list = customerService.findAllCustomer();
    		model.addAttribute("list", list);
    		return "index";	
    	}
    }

##### index.jsp： #####

<%@ page language="java" contentType="text/html; charset=UTF-8"
        pageEncoding="UTF-8"%>
    <%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
    <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
    <html>
    <head>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/>
    <title>客户管理页面</title>
    </head>
    <body>
    	<h2 align="center">客户管理系统</h2>
    		<table border="1px" align="center" width="700px">
    			<tr align="center">
    				<td>客户ID</td>
    				<td>客户姓名</td>
    				<td>客户密码</td>
    				<td>客户地址</td>
    				<td>客户手机</td>
    				<td>客户邮箱</td>
    			</tr>
    			<c:forEach items="${list}" var="c">
    				<tr align="center">
    					<td>${c.c_id}</td>
    	                <td>${c.c_name}</td>
    	                <td>${c.c_password}</td>
    		            <td>${c.c_address}</td>
    		            <td>${c.c_phone}</td>
    		            <td>${c.c_email}</td>
    				</tr>
    			</c:forEach>
    		</table>
    </body>
    </html>

### 5、工程测试 ###

在该工程下找到Spring Boot入口类：SpringbootCustomerApplication.java，单击鼠标右键，选中Run As -->Spring Boot App运行。在浏览器地址栏访问http://localhost:8090/findAll，其结果如下：
