在日志记录期间屏蔽Java中的某些字符串属性?

public class Employee {
    private String username;
    private String password;
    private String city;

    @Override
    public String toString() {
        return "username=" + username + " city=" + city;

    }

    public static void main(String[] args) {
        System.out.println(new Employee().toString());
    }
}

例如,您还可以替换日志记录中的密码字符串

 String maskedPassword = s.replaceAll("password=[^&]*", "password=***");

logging filter 进行此类更换。

创建一个名为MaskedString的类,该类基本上只是字符串的替代品,但有一个toString方法,该方法不输出实际密码:

public class MaskedString(){
    private String maskedString;

    MaskedString(){
        maskedString = "";
    }

    MaskedString(String string){
        maskedString = string;
    }

    public String getActualString(){
        return maskedString;
    }

    public String setString(String string){
        maskedString = string;
    }

    public String toString(){
        return "Not the actual string!";
    }
}

龙目岛 ,尝试ToString的排除选项。

@Data
@ToString(exclude = {"password"})
public class Employee {
    private String username;
    private String password;
    private String city;
}
