Exception in thread "main" org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.yubai.el.ELConfig' available

at org.springframework.beans.factory.support.DefaultListableBeanFactory.getBean(DefaultListableBeanFactory.java:353)
at org.springframework.beans.factory.support.DefaultListableBeanFactory.getBean(DefaultListableBeanFactory.java:340)

源代码：

package com.yubai.el;

import org.springframework.context.annotation.AnnotationConfigApplicationContext;

public class Main {
public static void main(String[] args) {
AnnotationConfigApplicationContext context = new AnnotationConfigApplicationContext("ELConfig.class");

ELConfig resourceService = context.getBean(ELConfig.class);
resourceService.outputResource();
context.close();
}
}

出错原因：

从错误信息可知：没有此bean注入容器中，所以可能没有用@Service或者@Bean注入此类。还有可能是别的错误导致，如上错误。

AnnotationConfigApplicationContext context = new AnnotationConfigApplicationContext(“ELConfig.class”);

AnnotationConfigApplicationContext作为spring容器，接收输入一个配置类作为参数。接收的类不要加双引号。

修改代码如下：

package com.yubai.el;

import org.springframework.context.annotation.AnnotationConfigApplicationContext;

public class Main {
public static void main(String[] args) {
AnnotationConfigApplicationContext context = new AnnotationConfigApplicationContext(ELConfig.class);

ELConfig resourceService = context.getBean(ELConfig.class);
resourceService.outputResource();
context.close();
}
}

此时运行正常
