【Spring】基于XML的IOC案例

代码结构：

bean.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://www.springframework.org/schema/beanshttps://www.springframework.org/schema/beans/spring-beans.xsd"><!--配置Service--><bean id="accountService" class="com.itheima.service.impl.AccountServiceImpl"><!--注入dao--><property name="accountDao" ref="accountDao"></property></bean><!--配置dao对象--><bean id="accountDao" class="com.itheima.dao.impl.AccountDaoImpl"><!--注入QueryRunner--><property name="runner" ref="runner"></property></bean><!--配置QueryBean--><bean id="runner" class="org.apache.commons.dbutils.QueryRunner"><!--配置数据源--><constructor-arg name="ds" ref="dataSource"></constructor-arg></bean><!--配置数据源--><bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"><!--连接数据库的四大必备信息--><property name="driverClass" value="com.mysql.jdbc.Driver"></property><property name="jdbcUrl" value="jdbc:mysql://localhost:3306/eesy"></property><property name="user" value="root"></property><property name="password" value="root"></property></bean>

业务接口层

/*** 账户的业务层接口*/
public interface IAccountService {/*** 查询所有* @return*/List<Account> findAllAccount();/*** 查询一个* @return*/Account findAccountById(Integer accountId);/*** 保存* @param account*/void saveAccount(Account account);/*** 更新* @param account*/void updateAccount(Account account);/*** 删除* @param accountId*/void deleteAccount(Integer accountId);
}

业务接口层实现

/*** 账户的业务成是先烈*/
public class AccountServiceImpl implements IAccountService {public void setAccountDao(IAccountDao accountDao) {this.accountDao = accountDao;}private IAccountDao accountDao;@Overridepublic List<Account> findAllAccount() {return accountDao.findAllAccount();}@Overridepublic Account findAccountById(Integer accountId) {return accountDao.findAccountById(accountId);}@Overridepublic void saveAccount(Account account) {accountDao.saveAccount(account);}@Overridepublic void updateAccount(Account account) {accountDao.updateAccount(account);}@Overridepublic void deleteAccount(Integer accountId) {accountDao.deleteAccount(accountId);}
}

持久层接口

/*** 账户的持久层接口*/
public interface IAccountDao {/*** 查询所有* @return*/List<Account> findAllAccount();/*** 查询一个* @return*/Account findAccountById(Integer accountId);/*** 保存* @param account*/void saveAccount(Account account);/*** 更新* @param account*/void updateAccount(Account account);/*** 删除* @param accountId*/void deleteAccount(Integer accountId);
}

持久层接口实现

/*** 账户的持久层实现类*/
public class AccountDaoImpl implements IAccountDao {public void setRunner(QueryRunner runner) {this.runner = runner;}private QueryRunner runner;@Overridepublic List<Account> findAllAccount() {try {return runner.query("select * from account",new BeanListHandler<Account>(Account.class));} catch (Exception e) {throw new RuntimeException();}}@Overridepublic Account findAccountById(Integer accountId) {try {return runner.query("select * from account where id = ?",new BeanHandler<Account>(Account.class),accountId);} catch (Exception e) {throw new RuntimeException();}}@Overridepublic void saveAccount(Account account) {try {runner.update("insert into account(name,money)values(?,?)",account.getName(),account.getMoney());} catch (Exception e) {throw new RuntimeException();}}@Overridepublic void updateAccount(Account account) {try {runner.update("update account set name=?,money=? where id=?",account.getName(),account.getMoney(),account.getId());} catch (Exception e) {throw new RuntimeException();}}@Overridepublic void deleteAccount(Integer accountId) {try {runner.update("delete from account where id=?",accountId);} catch (Exception e) {throw new RuntimeException();}}
}

实体层

/*** 账户的实体类*/
public class Account implements Serializable {private Integer id;private String name;private Float 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 Float getMoney() {return money;}public void setMoney(Float money) {this.money = money;}@Overridepublic String toString() {return "Account{" +"id=" + id +", name='" + name + '\'' +", money=" + money +'}';}
}

测试类

/*** 使用Junited单元测试，测试我们的配置*/
public class AccountServiceTest {@Testpublic void testFindAll() {//1. 获取容器ApplicationContext ac=new ClassPathXmlApplicationContext("bean.xml");//2. 得到业务层对象IAccountService as=ac.getBean("accountService",IAccountService.class);//3. 执行方法List<Account> accounts=as.findAllAccount();for(Account account:accounts){System.out.println(account);}}@Testpublic void testFindOne() {//1. 获取容器ApplicationContext ac=new ClassPathXmlApplicationContext("bean.xml");//2. 得到业务层对象IAccountService as=ac.getBean("accountService",IAccountService.class);//3. 执行方法Account account=as.findAccountById(1);}@Testpublic void testSave() {Account account=new Account();account.setName("zhaofen");account.setMoney(200f);//1. 获取容器ApplicationContext ac=new ClassPathXmlApplicationContext("bean.xml");//2. 得到业务层对象IAccountService as=ac.getBean("accountService",IAccountService.class);//3. 执行方法as.saveAccount(account);}@Testpublic void testUpdate() {//1. 获取容器ApplicationContext ac=new ClassPathXmlApplicationContext("bean.xml");//2. 得到业务层对象IAccountService as=ac.getBean("accountService",IAccountService.class);//3. 执行方法Account account=as.findAccountById(4);account.setName("test");as.updateAccount(account);}@Testpublic void testDelete() {//1. 获取容器ApplicationContext ac=new ClassPathXmlApplicationContext("bean.xml");//2. 得到业务层对象IAccountService as=ac.getBean("accountService",IAccountService.class);//3. 执行方法as.deleteAccount(4);}
}
