- html - 出于某种原因,IE8 对我的 Sass 文件中继承的 html5 CSS 不友好?
- JMeter 在响应断言中使用 span 标签的问题
- html - 在 :hover and :active? 上具有不同效果的 CSS 动画
- html - 相对于居中的 html 内容固定的 CSS 重复背景?
当我使用 Spring boot 进行开发时,发生了 org.springframework.beans.factory.UnsatisfiedDependencyException。
言归正传,我没有改变任何东西。
我尝试检查 fileUtil 类,但没有任何具体问题。并执行“Project clean”并重新启动 Eclipse。
在谷歌上搜索后,有人说“检查你的注释是否有效”所以我检查了注释,但没有什么可猜测的
但错误仍然没有解决..我将向您展示我的代码
这是异常(exception)。

这是 [com.m2u.chatbotany.common.utils.ConfigProperties]
(@Component <<- I added this annotation but nothing change )
public class ConfigProperties {
private static final Logger LOG = LoggerFactory.getLogger(ConfigProperties.class);
private Properties properties;
public ConfigProperties() {
LOG.info("ConfigProperties");
}
// ~ Implementation Method. ~~~~~~~~
// ~ Self Methods. ~~~~~~~~~~~~~~~~~
public final void init() {
// 환경 변수 설정 log 출력
if (this.properties != null) {
LOG.info("Initialize Config Variables");
// LOG.info(JsonUtil.marshallingJsonWithPretty(this.properties));
}
}
// ~ Getter and Setter
// ==============================================================================================
public final void setProperties(final Properties properties) {
this.properties = properties;
}
public final String getString(final String key) {
return this.properties.getProperty(key);
}
public final Integer getInteger(final String key) {
String value = this.properties.getProperty(key);
return new Integer(value);
}
}
这是 fileUtil
/**
* 업로드 파일 유틸
*/
@Component("fileUtil")
public class FileUtil {
/**
* The constant LOG.
*/
private static final Logger LOG = LoggerFactory.getLogger(FileUtil.class);
/**
* The Config.
*/
@Autowired
private ConfigProperties config;
......
}
这个问题我从来没见过...
我的应用程序直到 3 小时前才完全正常工作。重复一遍,我没有改变任何东西
等待您的帮助。
最佳答案
No qualifying bean of type [com.m2u.chatbotany.common.utils.ConfigProperties]
上述错误是因为在 FileUtil
中您已 Autowiring ConfigProperties
但 ConfigProperties.class
未使用 Stereotype (@Component, @服务等)
因此添加如下所示的@Component注释
@Component
public class ConfigProperties {
// Code logic
}
