LeerProperties.java是

package eusurvey.auxiliar;

import org.springframework.beans.factory.annotation.Value;

public class LeerProperties {

    @Value("${correos.correosalida}")
    private  String correosalida;

      public  String PropertyValue() {

            return  correosalida;
        }
}

correosalida的值为null。

如何从correos.properties获取属性？

Answer 1

您是否尝试使用classpath访问该文件？

应该是这样的：

<context:property-placeholder location="classpath:correos.properties" order="1" ignore-unresolvable="true" />

编辑：

尝试以这种方式加载：

<util:properties id="correos" location="classpath:correos.properties"/>

不应该和＃34;＃＆＃34;而不是＆＃34; $＆＃34;？

@Value("#{correos.correosalida}")
