springboot之读取配置文件

1.propertie配置读取数据

/**
 * 通过value取配置文件中的数据
 */
@Component
@PropertySource(value = {"config/db-config.properties"})   
public class InfoConfig1 {

    @Value("${db.username}")
    private String useranme;
    @Value("${db.password}")
    private String password;

    public String getUseranme() {
        return useranme;
    }

    public void setUseranme(String useranme) {
        this.useranme = useranme;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    @Override
    public String toString() {
        return "";
    }

}

2.取值
  

@RestController
public class InConfigController {
    @Autowired
    private Environment env;
    @Value("${db.username}")
    private String username;

    @RequestMapping(value = "/info")
    public String getValue() {
        String username = env.getProperty("db.username");
        String password = env.getProperty("db.password");
        return username;
    }

    @RequestMapping(value = "/info2")
    public void getValue1() {
        System.out.println(username);
    }
}
