Spring XML 配置 bean 的錯誤
阿新 • • 發佈：2022-03-09
1 bean2.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/beans http://www.springframework.org/schema/beans/spring-beans.xsd"> <!--1 service 和 DAO 物件建立--> <bean id="userService" class="com.spring5.service.UserService"> <!-- 注入 userDAO 物件 ref 建立 userDAO 物件 bean 標籤 id 值 --> <property name="userDAO" ref="userDAOImpl"/> </bean> <bean id="userDAOImpl" class="com.spring5.DAO.UserDAOImpl"/> </beans>
2 UserService 類
package com.spring5.service; import com.spring5.DAO.UserDAO; import com.spring5.DAO.UserDAOImpl; public class UserService { // 1 建立 UserDAO 型別屬性 private UserDAO userDAO; public void setUserDAO(UserDAO userDAO) { this.userDAO = userDAO; }public void add() { System.out.println("service add..."); userDAO.update(); // 原始方法 /*UserDAO userDAO = new UserDAOImpl(); userDAO.update();*/ } }
3 測試類 TestBean
package com.spring5.testDemo; import com.spring5.bean.Employee; import com.spring5.service.UserService; import org.junit.jupiter.api.Test; import org.springframework.context.ApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext; public class TestBean { @Test public void testBean1() { ApplicationContext context = new ClassPathXmlApplicationContext("bean2.xml"); UserService userService = context.getBean("userService", UserService.class); userService.add(); } }

5 解決方法
- ClassPathXmlApplicationContext讀取xml檔案的，就把配置檔案appicationContext.xml放到src的那一層。
- 如果使用FileSystemXmlApplicationContext讀取，則需把配置檔案放到整個專案的根目錄。
