SSM

<>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：

org.apache.tomcat.embed

tomcat-embed-jasper

javax.servletjstl

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 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dbcp连接池 dbcp2: connection-init-sqls: characterEncoding=utf-8 initial-size: 5

max-idle: 100 max-wait-millis: 10000 min-idle: 5 test-on-borrow: true

test-while-idle: true time-between-eviction-runs-millis: 27800 #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：

<>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 findAllCustomer(); //查询所有客户信息 }

<>CustomerMapper.xml：

<?xml version="1.0" encoding="UTF-8"?> /p>

"-//mybatis.org//DTD Mapper 3.0//EN"

"http://mybatis.org/dtd/mybatis-3-mapper.dtd">

namespace="com.ming.ssm.mapper.CustomerMapper">

SELECT * FROM `customer`

<>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 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 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 list = customerService.findAllCustomer();

model.addAttribute("list", list); return "index"; } }

<>index.jsp：

pageEncoding="UTF-8"%>

prefix="c"%>/p>

"http://www.w3.org/TR/html4/loose.dtd">

客户管理页面

客户管理系统

客户ID

客户姓名

客户密码

客户地址 td>

客户手机

客户邮箱

align="center">

${c.c_id} ${c.c_name} ${c.c_password}${c.c_address } ${c.c_phone } ${c.c_email }

c:forEach>

<>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：
