此处省略很多很多字…
2.导入maven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>1.8.4</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-webmvc</artifactId><version>5.0.5.RELEASE</version></dependency><!-- servlet和jsp相关--><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>3.4.6</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>com.mchange</groupId><artifactId>c3p0</artifactId><version>0.9.5.2</version></dependency><dependency><groupId>junit</groupId><artifactId>junit</artifactId><version>4.12</version><scope>test</scope></dependency><dependency><groupId>jstl</groupId><artifactId>jstl</artifactId><version>1.2</version></dependency></dependencies>
3.编写实体类
public class Account {private Integer id;private String name;private Double money;//get和set方法省略}
4.编写Mapper接口
public interface AccountMapper {public void save(Account account);public List<Account> findAll();}
5.编写Service接口
public interface AccountService {public void save(Account account);public List<Account> findAll();}
6.编写Service接口实现
@Service("accountService")public class AccountServiceImpl implements AccountService {@Autowiredprivate AccountMapper accountMapper;@Overridepublic void save(Account account) {accountMapper.save(account);}@Overridepublic List<Account> findAll() {return accountMapper.findAll();}}
7.编写Controller
@Controller@RequestMapping("/account")public class AccountController {@Autowiredprivate AccountService accountService;//保存@RequestMapping(value = "/save",produces = "text/html;charset=UTF-8")@ResponseBodypublic String save(Account account){accountService.save(account);return "保存成功";}//查询@RequestMapping("/findAll")public ModelAndView findAll(){List<Account> accountList = accountService.findAll();ModelAndView modelAndView=new ModelAndView();modelAndView.addObject("accountList",accountList);modelAndView.setViewName("accountList");return modelAndView;}}
8.编写添加页面
<%@ page contentType="text/html;charset=UTF-8" language="java" %><html><head><title>Title</title></head><body><h1>添加账户信息表单</h1><form name="accountForm" action="${pageContext.request.contextPath}/account/save" method="post">账户名称:<input type="text" name="name"><br>账户金额:<input type="text" name="money"><br><input type="submit" value="保存"><br></form></body></html>
9.编写列表页面
<%@ page contentType="text/html;charset=UTF-8" language="java" %><%@taglib prefix="c" uri="/jsp/jstl/core" %><html><head><title>Title</title></head><body><table><tr><th>账户id</th><th>账户名称</th><th>账户金额</th></tr><c:forEach items="${accountList}" var="account"><tr><td>${account.id}</td><td>${account.name}</td><td>${account.money}</td></tr></c:forEach></table></body></html>
10.编写相应配置文件
数据库连接信息文件：jdbc.properties
jdbc.driver=com.mysql.jdbc.Driverjdbc.url=jdbc:mysql://localhost:3306/testjdbc.username=rootjdbc.password=root
Spring配置文件：applicationContext.xml

MyBatis映射文件：AccountMapper.xml
<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE mapper PUBLIC "-////DTD Mapper 3.0//EN" "/dtd/mybatis-3-mapper.dtd"><mapper namespace="com.itzhuo.mapper.AccountMapper"><insert id="save" parameterType="account">insert into account values(#{id},#{name},#{money})</insert><select id="findAll" resultType="account">select * from account</select></mapper>

11.测试
启动Tomcat打开浏览器输入http://localhost:8080/save.jsp
保存
浏览器输入http://localhost:8080/account/findAll
