该案例是基于B站黑马上的ssm视频搭建的，是一个简单的form表单数据从前端jsp页面存储到数据库中，简单的实现了查询和添加操作，主要是用于理解SSM框架怎样才算整合完毕，话不多说，上代码！
该案例是用Maven工程搭建，用的IDEA！
目录结构如图：
前端页面

<h1>查询所有的账户信息</h1>
<c:forEach items="${list}" var="account">
${account.name} ${account.money} <br/>
</c:forEach>

</html>
前端简单的上传表单的页面以及打印查询结果的页面
接着上数据库的account表代码
数据库表
CREATE TABLE account(
id INT PRIMARY KEY AUTO_INCREMENT,
NAME VARCHAR(20),
money DOUBLE );

实体类（与数据库字段和表单字段对应）：
/**
* 账户信息，对应数据库的account表
*
* @author Cocowwy
* @create 2020-04-04-11:29
*/
public class Account {
private Integer id;
private String name;
private Double money;
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public Double getMoney() {
return money;
}
public void setMoney(Double money) {
this.money = money;
}
@Override
public String toString() {
return "Account{" +
"id=" + id +
", name='" + name + '\'' +
", money=" + money +
'}';
}
}
Controller层
/**
* web层
*
* @author Cocowwy
* @create 2020-04-04-11:44
*/
@Controller
@RequestMapping("/account")
public class AccountController {
@Autowired
private IAccountService accountService;
/**
* 查询
*
* @param model
* @return
*/
@RequestMapping("/findAll")
public String findAll(Model model) {
System.out.println("表现层，查询所有的账户信息");
//调用业务层方法
List<Account> list = accountService.findAll();
model.addAttribute("list", list);
System.out.println(list + "ccc");
return "list";
}
/**
* 保存
*
* @param account
* @return
*/
@RequestMapping("/save")
public void save(Account account, HttpServletRequest request, HttpServletResponse response) throws IOException {
//调用业务层方法
accountService.saveAccount(account);
response.sendRedirect(request.getContextPath()+"/account/findAll");
}
}
dao（不需要写实现类）
/**账户dao接口
* @author Cocowwy
* @create 2020-04-04-11:33
*/
@Repository
public interface IAccountDao {
//查询所有账户信息
@Select("select * from account")
public List<Account> findAll();
//保存用户信息
@Insert("insert into account(name,money) values(#{name},#{money})")
public void saveAccount(Account account);
}
Service层接口
/**
* @author Cocowwy
* @create 2020-04-04-11:37
*/
public interface IAccountService {
//查询所有账户信息
public List<Account> findAll();
//保存用户信息
public void saveAccount(Account account);
}
Service层实现类
@Service("accountService")
public class IAccountServiceimpl implements IAccountService {
@Autowired
private IAccountDao accountDao;
@Override
public List<Account> findAll() {
System.out.println("业务层查询所有的账户信息");
return accountDao.findAll();
}
@Override
public void saveAccount(Account account) {
System.out.println("业务层保存账户");
accountDao.saveAccount(account);
}
}
以上就是全部配置，然后启动tomcat运行效果如下：
提交后重定向到其他页面
以上就是基于SSM框架的整合小案例！
如果有错误请见谅，欢迎大家指出，谢谢！
