JUtil运行成功但是控制台打印的结果是不可读

Question

Answer 1

user是对象类型，直接打印的话打印出的是这个对象的引用地址，而不是对象的值，需要调用对象的toString方法来进行打印，这样就是对象的值了，正确输出为System.out.println(user.toString());
类似下面这样

@Override
    public String toString() {
        return "User{" +
                "userid='" + userid + '\'' +
                ", name='" + name + '\'' +
                ", department=" + Arrays.toString(department) +
                ", position='" + position + '\'' +
                ", mobile='" + mobile + '\'' +
                ", gender='" + gender + '\'' +
                ", email='" + email + '\'' +
                ", weixinid='" + weixinid + '\'' +
                ", enable=" + enable +
                ", avatar_mediaid='" + avatar_mediaid + '\'' +
                ", avatar='" + avatar + '\'' +
                ", status=" + status +
                ", extattr=" + extattr +
                '}';
    }
