springboot 使用@ConfigurationProperties注入配置属性

导入依赖，让springboot支持@ConfigurationProperties 注解

    <!-- 支持 @ConfigurationProperties 注解 -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-configuration-processor</artifactId>
            <version>{SpringBoot的版本}</version>
        </dependency>

配置文件：

connection:
  username: admin
  password: kyjufskifas2jsfs
  remoteAddress: 192.168.1.1

配置文件注册类：

@Component
@ConfigurationProperties(prefix="connection")
public class Properties {
    private String username;
    private String remoteAddress;
    private String password ;

    public String getUsername() {
        return username;
    }
    public void setUsername(String username) {
        this.username = username;
    }
    public String getRemoteAddress() {
        return remoteAddress;
    }
    public void setRemoteAddress(String remoteAddress) {
        this.remoteAddress = remoteAddress;
    }
    public String getPassword() {
        return password;
    }
    public void setPassword(String password) {
        this.password = password;
    }

}

使用时直接注入即可：

@RequestMapping("/test")
@RestController
public class TestController {

    @Autowired
    private Properties properties;

    @GetMapping("/test")
    public void test(){
        System.out.println("===================="+properties.getPassword());//====================kyjufskifas2jsfs
    }
}
