浅谈springboot 属性定义

# 自定义属性boot.userName = yuxi

 @Value(value = "${boot.userName}") private String userName;

# 复杂属性test.id=1test.name=xiaoyuxixitest.money=100000000

//需要注意这个属性是必须的@ConfigurationProperties(prefix = "test")public class Account {  private int id;  private String name;  private double money;  public int getId() {    return id;  }  public void setId(int id) {    this.id = id;  }  public String getName() {    return name;  }  public void setName(String name) {    this.name = name;  }  public double getMoney() {    return money;  }  public void setMoney(double money) {    this.money = money;  }  @Override  public String toString() {    return "Account{" +        "id=" + id +        ", name='" + name + '/'' +        ", money=" + money +        '}';  }}

@RestController// 这个属性也是必须的@EnableConfigurationProperties({Account.class})public class HelloController {  //自定义属性  @Value(value = "${boot.userName}")  private String userName;  @Autowired  private Account account;  /**   * 复杂 属性自定义   *   * @return   */  @RequestMapping("/hard")  public Object getHardProperties() {    return account;  }  /**   * welcome spring boot   *   * @return   */  @RequestMapping(value = "/", method = RequestMethod.GET)  public String index() {    return "Greetings from Spring Boot! ";  }  /**   * 简单 属性自定义   *   * @return   */  @RequestMapping("/user")  public String getProperties() {    System.out.println(userName);    return userName;  }  }

# 配置文件获取lakala.id=1lakala.name=xiaoyuxixilakala.money=100000000

@Configuration@PropertySource(value = "classpath:test.properties")
