4.编写实体类

public class Account {
    private int id;
    private String name;
    private double money;
    //省略getter和setter方法
}

5.编写Mapper接口

public interface AccountMapper {
    //保存账户数据
    void save(Account account);
    //查询账户数据
    List findAll();
}

6.编写Service接口

public interface AccountService {
    void save(Account account); //保存账户数据
    List findAll(); //查询账户数据
}

7.编写Service接口实现

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

    @Autowired
    private AccountMapper accountMapper;

    @Override
    public void save(Account account) {
        accountMapper.save(account);
    }

    @Override
    public List findAll() {
        return accountMapper.findAll();
    }
}

8.编写Controller

@Controller
public class AccountController {
    @Autowired
    private AccountService accountService;
    @RequestMapping("/save")
    @ResponseBody
    public String save(Account account){
        accountService.save(account);
        return "save success";
    }
    @RequestMapping("/findAll")
    public ModelAndView findAll(){
        ModelAndView modelAndView = new ModelAndView();
        modelAndView.setViewName("accountList");
        modelAndView.addObject("accountList",accountService.findAll());
        return modelAndView;
    }
}

9.编写添加页面

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


    


    
保存账户信息表单
    

        用户名称

        账户金额

        

    

10. 编写列表页面

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>


    


展示账户数据列表

        

    

        
账户id
        
账户名称
        
账户金额
    

    

            
${account.id}
            
${account.name}
            
${account.money}
        
    

11. 编写相应配置文件

applicationContext.xml

db.properties

#数据库连接信息
jdbc.url=jdbc:mysql:///ssm
jdbc.driver=com.mysql.jdbc.Driver
jdbc.user=root
jdbc.pwd=123456

log4j.properties

#
# Hibernate, Relational Persistence for Idiomatic Java
#
# License: GNU Lesser General Public License (LGPL), version 2.1 or later.
# See the lgpl.txt file in the root directory or .
#

### direct log messages to stdout ###
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.err
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n

### direct messages to file hibernate.log ###
#log4j.appender.file=org.apache.log4j.FileAppender
#log4j.appender.file.File=hibernate.log
#log4j.appender.file.layout=org.apache.log4j.PatternLayout
#log4j.appender.file.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n

### set log levels - for more verbose logging change 'info' to 'debug' ###

log4j.rootLogger=all, stdout

spring-mvc.xml

web.xml

AccountMapper.xml

    
        insert into account values(null,#{name},#{money})
    

    
        select * from account
    

12. 测试添加账户

13. 测试账户列表
