之前写了关于读取自定义配置的文章springboot~yml里的自定义配置,而今天主要说一下对复杂配置信息的读取方法,我们简单的配置用@Value注解就可以了,而结构复杂的一般使用@ConfigurationProperties来实现,下面说一下。
config-attributes:
value: 345 #对应单个值
valueArray: 1,2,3,4,5,6,7,8,9 #对应数组
valueList: #对应list
-13579
-246810
valueMap: #对应map
name: lili
age: 20
sex: female
valueMapList: #对应list<map>
- name: bob
age: 21
- name: caven
age: 31
@SpringBootApplication
@ConfigurationProperties
public class BootstrapConfig {
public static void main(String[] args) {
SpringApplication.run(BasicApplication.class, args);
}
}
@Component
@Getter
@Setter
@ConfigurationProperties(prefix = "config-attributes")
@ToString
public class Config {
private String value;
private String[] valueArray;
private List<String> valueList;
private HashMap<String, String> valueMap;
private List<Map<String, String>> valueMapList;
}
@Autowired
private Config config;
@Test
public void readConfigNode() {
System.out.println(config.toString());
}
Config(value=345, valueArray=[1, 2, 3, 4, 5, 6, 7, 8, 9], valueList=[-13579 -246810], valueMap={name=lili, age=20, sex=female}, valueMapList=[{name=bob, age=21}, {name=caven, age=31}])
总结:简单配置用@Value,复杂配置用ConfigurationProperties。
