Spring XML 配置 bean 的错误
本文主要是介绍Spring XML 配置 bean 的错误，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！
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 对象创建-->
<bean id="userService" class="com.spring5.service.UserService">
<!-- 注入 userDAO 对象 ref 创建 userDAO 对象 bean 标签 id 值 -->
<property name="userDAO" ref="userDAOImpl"/>
</bean>
<bean id="userDAOImpl" class="com.spring5.DAO.UserDAOImpl"/>
</beans>
2 UserService 类
package com.spring5.service;
import com.spring5.DAO.UserDAO;
import com.spring5.DAO.UserDAOImpl;
public class UserService {
// 1 创建 UserDAO 类型属性
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 测试类 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();
}
}
4 Error

5 解决方法
- ClassPathXmlApplicationContext读取xml文件的，就把配置文件appicationContext.xml放到src的那一层。
- 如果使用FileSystemXmlApplicationContext读取，则需把配置文件放到整个项目的根目录。
