SSM基础整合

一、 搭建整合环境

• SSM整合方式：XML + 注解的方式
• 环境为idea的maven web原型工程

1. Maven依赖配置

2. Web配置

• 而我们的web.xml中只配置了启动时加载SpringMVC的配置文件导致Spring的配置文件的注解没有被加载。为了解决这个问题需要使用web服务器的监听器来解决加载问题
• 使用监听器原理：Web服务器中有一个全局ServletContext对象，每个Web发布项目只有一个，随着服务器启动和关闭而创建和销毁，因此我们可以创建一个监听器(spring-web中的ContextLoaderListener类)监听ServletContext对象的状态，只要这个对象一创建，就开始加载Spring配置文件，这样service中的类就会被扫描到。

<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

二、测试案例

实体类：

@Data
public class Account {
    private int id;
    private String name;
    private double money;
}

控制层代码

@Controller
public class AccountController {
    @Autowired
    AccountService service;

    @RequestMapping("/insert")
    public String account(Account account, Model model) {

        service.insertAccount(account);
        List<Account> list = service.findAll();
        model.addAttribute("accountList", list);
        return "ok";
    }
}

Dao层接口：

@Repository
public interface AccountDao {

    @Select("select * from tdte_db.spring_account")
    List<Account> findAll();

    @Insert("insert into tdte_db.spring_account(name,money) values (#{name},#{money})")
    int insertAccount(Account account);
}

业务层代码

public interface AccountService {
    List<Account> findAll();
    int insertAccount(Account account);
}

@Service("accountService")
public class AccountServiceImpl implements AccountService {

    @Autowired
    private AccountDao dao;

    @Override
    public List<Account> findAll() {
        return dao.findAll();
    }

    @Override
    public int insertAccount(Account account) {
        return dao.insertAccount(account);
    }
}

表单页面：

<%@ page contentType="text/html;charset=UTF-8" language="java" %>


  



  
    用户名：
    
  
  

  
    薪资：
    
  
  

成功跳转页：
