- 使用 ConfigurationProperties 来使用 properties 的值。启用自定义配置： @Configuration @EnableConfigurationProperties({YourConfigClass}.class)@ConfigurationProperties(prefix) 注解自定义的 YourConfigClass通过 bean 来使用自定义的配置信息类@SpringBootApplication@EnableConfigurationProperties(TestConfigurationProperties.class)public class DemoApplication{ @Autowired TestConfigurationProperties testConfig; public static void main(String[] args) { SpringApplication.run(DemoApplication.class, args); new DemoApplication().testConfig.printProperties(); } @PostConstruct private void init(){ testConfig.printProperties(); }}@ConfigurationProperties(“testconfig”)public class TestConfigurationProperties { private String first; private String second; private String third; private String fourth; private String fifth; private String sixth; private String seventh; private String eightth; //getters and setters这样就可以通过 Bean 来使用。2. 通过 @Value 使用通过注解 @Value("${testconfig.first}") 可以给变量赋值成 配置 testconfig.first 的信息。@Componentpublic class TestValue { @Value("${testconfig.first}") private String first; @Value("${testconfig.second}") private String second; @Value("${testconfig.third}") private String third; @Value("${testconfig.fourth}") private String fourth; @Value("${testconfig.fifth}") private String fifth; @Value("${testconfig.sixth}") private String sixth; @Value("${testconfig.seventh}") private String seventh; @Value("${testconfig.eightth}") private String eightth; public String getFirst() { return first; } public void setFirst(String first) { this.first = first; } public String getSecond() { return second; } public void setSecond(String second) { this.second = second; } public String getThird() { return third; } public void setThird(String third) { this.third = third; } public String getFourth() { return fourth; } public void setFourth(String fourth) { this.fourth = fourth; } public String getFifth() { return fifth; } public void setFifth(String fifth) { this.fifth = fifth; } public String getSixth() { return sixth; } public void setSixth(String sixth) { this.sixth = sixth; } public String getSeventh() { return seventh; } public void setSeventh(String seventh) { this.seventh = seventh; } public String getEightth() { return eightth; } public void setEightth(String eightth) { this.eightth = eightth; } public void printProperties(){ System.out.println("\ntest value:"); System.out.println(“first: " + first); System.out.println(“second: " + second); System.out.println(“third: " + third); System.out.println(“fourth: " + fourth); System.out.println(“fifth: " + fifth); System.out.println(“sixth: " + sixth); System.out.println(“seventh: " + seventh); System.out.println(“eightth: " + eightth); }}输出为：test value:first: ./config/second: ./config/ymlthird: classpath/config/fourth: classpathfifth: ./config/sixth: ./config/seventh: ./config/eightth: ./config/
