1、创建数据库
2、创建表
3、创建maven工程
导入坐标
<dependencies><!--spring相关--><dependency><groupId>org.springframework</groupId><artifactId>spring-context</artifactId><version>5.0.5.RELEASE</version></dependency><dependency><groupId>org.aspectj</groupId><artifactId>aspectjweaver</artifactId><version>1.8.7</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-jdbc</artifactId><version>5.0.5.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-tx</artifactId><version>5.0.5.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-test</artifactId><version>5.0.5.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-webmvc</artifactId><version>5.0.5.RELEASE</version></dependency><!--servlet和jsp--><dependency><groupId>javax.servlet</groupId><artifactId>servlet-api</artifactId><version>2.5</version></dependency><dependency><groupId>javax.servlet.jsp</groupId><artifactId>jsp-api</artifactId><version>2.0</version></dependency><!--mybatis相关--><dependency><groupId>org.mybatis</groupId><artifactId>mybatis</artifactId><version>3.4.5</version></dependency><dependency><groupId>org.mybatis</groupId><artifactId>mybatis-spring</artifactId><version>1.3.1</version></dependency><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><version>5.1.6</version></dependency><dependency><groupId>c3p0</groupId><artifactId>c3p0</artifactId><version>0.9.1.2</version></dependency><dependency><groupId>junit</groupId><artifactId>junit</artifactId><version>4.12</version></dependency><dependency><groupId>jstl</groupId><artifactId>jstl</artifactId><version>1.2</version></dependency></dependencies>
4、编写实体类
package com.xmp.domain;
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;
}
}
5、编写Mapper接口
packagecom.xmp.mapper; importcom.xmp.domain.Account; importjava.util.List; publicinterfaceAccountMapper { publicvoidsave(Accountaccount); publicList<Account>findAll(); }
6、编写Service接口
packagecom.xmp.service; importcom.xmp.domain.Account; importjava.util.List; publicinterfaceAccountService { publicvoidsave(Accountaccount); publicList<Account>findAll(); }
7、编写Service接口实现
package com.xmp.service.impl;
import com.xmp.domain.Account;
import com.xmp.mapper.AccountMapper;
import com.xmp.service.AccountService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import java.util.List;
@Service("accountService")
public class AccountServiceImpl implements AccountService {
@Autowired
private AccountMapper accountMapper;
@Override
public void save(Account account) {
accountMapper.save(account);
}
@Override
public List<Account> findAll() {
return accountMapper.findAll();
}
}
8、编写Controller
packagecom.xmp.controller; importcom.xmp.domain.Account; importcom.xmp.service.AccountService; importorg.springframework.beans.factory.annotation.Autowired; importorg.springframework.stereotype.Controller; importorg.springframework.web.bind.annotation.RequestMapping; importorg.springframework.web.bind.annotation.ResponseBody; importorg.springframework.web.servlet.ModelAndView; importjava.util.List; "/account") (publicclassAccountController { privateAccountServiceaccountService; //保存value="/save",produces="text/html;charset=UTF-8") (publicStringsave(Accountaccount){ accountService.save(account); return"保存成功"; } //查询"/findAll") (publicModelAndViewfindAll(){ List<Account>accountList=accountService.findAll(); ModelAndViewmodelAndView=newModelAndView(); modelAndView.addObject("accountList",accountList); modelAndView.setViewName("accountList"); returnmodelAndView; } }
9、编写添加页面
<%pagecontentType="text/html;charset=UTF-8"language="java"%><html><head><title>Title</title></head><body><h1>添加账户信息表单</h1><formname="accountForm"action="${pageContext.request.contextPath}/account/save"method="post">账户名称:<inputtype="text"name="name"><br>账户金额:<inputtype="text"name="money"><br><inputtype="submit"value="保存"><br></form></body></html>
10、编写列表页面
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<html>
<head>
<title>Title</title>
</head>
<body>
<h1>展示账户数据列表</h1>
<table border="1">
<tr>
<th>账户id</th>
<th>账户名称</th>
<th>账户金额</th>
</tr>
<c:forEach items="${accountList}" var="account">
<tr>
<td>${account.id}</td>
<td>${account.name}</td>
<td>${account.money}</td>
</tr>
</c:forEach>
</table>
</body>
</html>
11、编写相应配置文件
