前言
在使用play框架,通过
Play.application().configuration().getString
获取配置项信息时,运行报错不能注入。
Caused by: org.springframework.beans.factory.BeanCreationException:Could not autowire field
错误信息
Caused by: org.springframework.beans.BeanInstantiationException: Could not instantiate bean class [XXX]: Constructor threw exception; nested exception is Configuration error: Configuration error[reference.conf: 242-244: play.test.url has type OBJECT rather than STRING]
原因
检查了配置项的,发现有些配置项存在类似,但少一级的情况,如:
配置文件:
play.test.url=“url”
play.test.url.test1=“1”
play.test.url.test2=“2”
play.test.url.test3=“3”
程序引用:
protected final String url1 = Play.application().configuration().getString("play.test.url");
protected final String url2 = Play.application().configuration().getString("play.test.url.test1");
protected final String url3 = Play.application().configuration().getString("play.test.url.test2");
protected final String url4 = Play.application().configuration().getString("play.test.url.test3");
系统取"play.test.url" 的值时,连着后面跟的.testn都算进去了,所以成了个对象,相应的就报错:
has type OBJECT rather than STRING
注意
配置项的名称唯一,且不能存在有类似父子级关系的配置名称
