[英]Field or property cannot be found on object of type 'org.springframework.beans.factory.config.BeanExpressionContext
[英]No setter found for property 'location' in class 'org.springframework.beans.factory.config.PropertyPlaceholderConfigurer'
設置PropertyPlaceholderConfigurer的location屬性時,我的bean配置文件中出現此錯誤。 有人可以幫我解決這個問題嗎?
錯誤是
在類'org.springframework.beans.factory.config.PropertyPlaceholderConfigurer'中找不到屬性'location'的設置器
這是我的employee-servlet.xml

我實際上已經從以下網站獲取了此示例: https : //howtodoinjava.com/spring-orm/spring-hibernate-integration-example/
您是否在鏈接的示例中查看了使用的spring版本? 他們使用Spring 3.0.5 ,很可能您使用的是最新版本,並且location
字段不再存在。
如果查看Spring核心版本5.1.2.RELEASE中的PropertiesLoaderSupport
的源代碼,您會看到該字段現在被命名為locations
並且存在多個設置方法。
/**
* Set a location of a properties file to be loaded.
* <p>Can point to a classic properties file or to an XML file
* that follows JDK 1.5's properties XML format.
*/
public void setLocation(Resource location) {
this.locations = new Resource[] {location};
}
/**
* Set locations of properties files to be loaded.
* <p>Can point to classic properties files or to XML files
* that follow JDK 1.5's properties XML format.
* <p>Note: Properties defined in later files will override
* properties defined earlier files, in case of overlapping keys.
* Hence, make sure that the most specific files are the last
* ones in the given list of locations.
*/
public void setLocations(Resource... locations) {
this.locations = locations;
