SSM framework integration of small White

1. The SSM framework integration directory

The basic framework of the SSM is as follows:

2. Database table Account

CREATE DATABASE ssm;
CREATE TABLE account(
    id INT PRIMARY KEY AUTO_INCREMENT,
    NAME VARCHAR(100),
    money DOUBLE(7.2));INSERT INTO account VALUES(1,"KangK",5000), (2,"Jane",5000);
Copy the code

3. java

3.1 the Account

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

    @Override
    public String toString(a) {
        return "Account{" +
                "id=" + id +
                ", name='" + name + '\' ' +
                ", money=" + money +
                '} ';
    }

    public int getId(a) {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getName(a) {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public double getMoney(a) {
        return money;
    }

    public void setMoney(double money) {
        this.money = money; }}Copy the code

3.2 AccountMapper

public interface AccountMapper {

    List<Account> selectAll(a);

    void saveAccount(Account account);

}
Copy the code

3.3 AccountService

public interface AccountService {
    List<Account> findAll(a);

    void save(Account account);
}
Copy the code

3.4 AccountServiceImpl

@Service
public class AccountServiceImpl implements AccountService {

    @Autowired
    private AccountMapper accountMapper;

    @Override
    public List<Account> findAll(a) {
        return accountMapper.selectAll();
    }

    @Override
    public void save(Account account) { accountMapper.saveAccount(account); }}Copy the code

3.5 AccountController

@RequestMapping("/account")
@Controller
public class AccountController {

    @Autowired
    private AccountService accountService;

    @RequestMapping("/select")
    @ResponseBody
    public ModelAndView select(ModelAndView modelAndView) {

        List<Account> accountList = accountService.findAll();

        for (Account account : accountList) {
            System.out.println(account);
        }

        modelAndView.addObject("accountList", accountList);
        modelAndView.setViewName("accountList");

        return modelAndView;
    }

    @RequestMapping("/insert")
    @ResponseBody
    public void update(Account account) { accountService.save(account); }}Copy the code
