@Configurationproperties注解和@Value注解
@ConfigurationProperties加在有@Configuration的类或者由@Bean注解的方法上,
另外一个类似的注解@EnableConfigurationProperties
用于允许@ConfigurationProperties
使用示例:
package hello; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; @SpringBootApplication public class App { public static void main(String[] args) { SpringApplication.run(App.class, args); } }
package hello.bean; //@Configuration //@ConfigurationProperties("user.properties") public class TestBean { private String name; private int age; public String getName() { return name; } public void setName(String name) { this.name = name; } public int getAge() { return age; } public void setAge(int age) { this.age = age; } }
package hello.config; import hello.bean.TestBean; import org.springframework.boot.context.properties.ConfigurationProperties; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; @Configuration public class BeanConfig { @ConfigurationProperties("user.properties") @Bean public TestBean getBean() { return new TestBean(); } }
package hello.controller; import hello.bean.TestBean; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.beans.factory.annotation.Value; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; import org.springframework.web.bind.annotation.RestController; @RestController public class Controller { @Autowired TestBean bean; @Value("${user.properties.name}") String name; @RequestMapping(value = "/test", method = RequestMethod.GET) public String get() { System.out.println(name); return bean.getName(); } @RequestMapping(value = "/post", method = RequestMethod.POST) public String post() { return "post"; } }
application.yml
user: properties: age: 18 name: zzzz
单个属性使用@Value
