标签：use 映射业务逻辑 bean private 标准 mamicode val 语法

@ConfigurationProperties(prefix="connection ")//与bean结合，为属性赋值通过指定类名来绑定该类的属性，支持松散语法，从属性文件获取类的属性，默认从全局配置文件中获取值；

我们想把配置文件的信息，读取并自动封装成实体类，这样子，我们在代码里面使用就轻松方便多了

@Component
@ConfigurationProperties(prefix="connection")
public class ConnectionSettings {

    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;
    }

}
