1.在resources目录下创建applicationContext.xml文件的代码如下：
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd"> <!--开启注解的扫描，希望处理service和dao，controller不需要Spring框架去处理--> <context:component-scan base-package="com.txw"> <!--配置哪些注解不扫描--> <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller" /> </context:component-scan> </beans>2.修改账户实现类的代码如下：
package com.txw.service.impl; import com.txw.domain.Account; import com.txw.service.AccountService; import org.springframework.stereotype.Service; import java.util.List; /** * 账户业务的实现类 * @author Adair */ @Service("accountService") @SuppressWarnings("all") // 注解警告信息 public class AccountServiceImpl implements AccountService { /** * 查询所有账户 * @return */ @Override public List<Account> findAll() { System.out.println("业务层：查询所有账户..."); return null; } /** * 保存帐户信息 * @param account */ @Override public void saveAccount(Account account) { System.out.println("业务层：保存帐户信息..."); } }声明@Service(“accountService”)是把业务层实现类叫交给IOC容器进行管理。 3.编写一个测试类的代码如下：
package com.txw.test; import com.txw.service.AccountService; import org.junit.Test; import org.springframework.context.ApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext; /** * 测试类 * @author Adair */ @SuppressWarnings("all") // 注解警告信息 public class TestSpring { @Test public void run1(){ // 加载配置文件 ApplicationContext ac = new ClassPathXmlApplicationContext("classpath:applicationContext.xml"); // 获取对象 AccountService as = (AccountService) ac.getBean("accountService"); // 调用方法 as.findAll(); } }运行结果如图所示：
