Question

使用postgres tomcat连接池的spring-boot数据库上的最大连接使用的默认值是什么？

有一个属性spring.datasource.maxActive，但当我尝试sysout它时，我得到了一个例外：

@Value("${spring.datasource.maxActive}")
private String act;

java.lang.IllegalArgumentException: Could not resolve placeholder 'spring.datasource.maxActive' in string value "${spring.datasource.maxActive}
