1.利用@ConfigurationProperties获取配置的值,@ConfigurationProperties是springboot提供的基于安全类型的配置放置。java
application.propertiesredis
spring.redis.host=127.0.0.1 spring.redis.port=6379 spring.redis.maxIdle=10 spring.redis.maxActive=20
RedisConfig.javaspring
@Configuration @ConfigurationProperties(prefix = "spring.redis") //会在application,properties,查找spring.redis开头的配置 public class RedisConfig { //必须有get set放入,不然值注入不进去 //匹配 spring.redis.host public String host; //匹配 spring.redis.port public int port; public String getHost() { return host; } public void setHost(String host) { this.host = host; } public int getPort() { return port; } public void setPort(int port) { this.port = port; }
2.利用@Value获取值,在springboot中若是不配置@PropertySource(value="classpath:redis.properties")(配置文件路径),默认是从application.properties中获取值,你也能够配置额外的@PropertySource,以下安全
@PropertySource(value="classpath:redis.properties") //@PropertySource(value="file:/home/config/redis.properties") public class RedisConfig { //从application.properties从获取 @Value("${spring.redis.host}") public String host; //从application.properties从获取 @Value("${spring.redis.port}") public int port; //从redis中获取.properties从获取 @Value("${name}") public String name; }
@ConfigurationPropertiesspringboot
为springboot 专用的属性注入属性 文件名必须是application.properties/applicaiton.yml 默认为全局文件中获取这些熟悉值 app
@Value,this
value 属性 处理能支持spel表达式之外 所有不如 ConfigurationPropertiesspa
@PropertySource.net
须要指定(classpath:xxxx.properties)加载指定的配置文件code
