Spring读取properties文件作为环境变量

 

在这个配置文件中，我们首先定义了类型为org.springframework.beans.factory.config.PropertyPlaceholderConfigurer的bean，这个bean用来将解析properties文件，spring可以使用此类，来将其他bean中类似EL表达式${abc}的值替换为配置文件的值。PropertyPlaceholderConfigurer类的locations属性是一个数组，也就是说可以指定多个配置文件。

 

 
	
        
        
        
            
                
                /WEB-INF/application.properties
            
        
    
	
	
        
    
	

 

java代码如下：

package org.sam.test;

public class DoggyTest {

	private String weight;

	DoggyTest() {
		System.out.println("On init DoggyTest:" + this.weight);
	}

	public String getWeight() {
		return weight;
	}

	public void setWeight(String weight) {
		this.weight = weight;
		System.out.println("On setting DoggyTest:" + this.weight);
	}


}
