Configuration problem: Failed to import bean definitions from URL location classpath:spring-mvc.xml

org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration

problem: Failed to import bean definitions from URL location [classpath:spring-mvc.xml]

配置问题：无法从 URL 位置导入 Bean 定义

排错思路：

• 查看bean是否注入成功

<!--将所有业务类注入Spring，可以通过配置或者注解-->
<bean id="BookServiceImpl" class="com.wei.service.BookServiceImpl">
    <property name="bookMapper" ref="bookMapper"/>
</bean>

• Junit单元测试，看代码是否能查询出来结果

import com.wei.pojo.Books;
import com.wei.service.BookServiceImpl;
import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class MyTest {
    @Test
    public void test() {
        //解析applicationContext.xml文件，生成管理相应的Bean对象
        ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");
        //getBean:参数即为Spring配置文件中的bean的id
        BookServiceImpl bookServiceImpl = (BookServiceImpl) context.getBean("BookServiceImpl");
        for (Books books : bookServiceImpl.queryAllBook()) {
            System.out.println(books);
        }
    }
}

如果查询出结果，说明问题出现在Spring

SpringMVC整合的时候没有调用service层的bean

applicationContext.xml没有注入bean

web.xml中绑定配置文件，配置的是spring-mvc.xml，没有service的bean

web.xml

<param-value>classpath:applicationContext.xml</param-value>

applicationContext.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">
    <import resource="classpath:spring-dao.xml"/>
    <import resource="classpath:spring-service.xml"/>
    <import resource="classpath:spring-mvc.xml"/>
</beans>
