Question

我需要保存BasePermission的子类

@NodeEntity
public class ExtendedPermission  extends BasePermission{

    /**
     * 
     */
    private static final long serialVersionUID = 1L;


    public static final Permission READ = new ExtendedPermission(1 << 0, 'R'); // 1
    public static final Permission WRITE = new ExtendedPermission(1 << 1, 'W'); // 2
    public static final Permission CREATE = new ExtendedPermission(1 << 2, 'C'); // 4
    public static final Permission DELETE = new ExtendedPermission(1 << 3, 'D'); // 8
    public static final Permission ADMINISTRATION = new ExtendedPermission(1 << 4, 'A'); // 16

    @GraphId
    private Long id;

    public ExtendedPermission() {
         super(0);
    }

    protected ExtendedPermission (int mask) {
        super(mask);
    }

    protected ExtendedPermission (int mask, char code) {
        super(mask, code);
    }

    public Long getId() {
        return id;
    }

    public void setId(Long id) {
        this.id = id;
    }

}

尝试保留Entity会出现以下错误：

Caused by: java.lang.RuntimeException: Unsupported value type class java.lang.Character. Supported value types are all java primitives (byte, char, short, int, 
long, float, double) and String, as well as arrays of all those types

现在code的{{1}}为BasePermission，为什么它被解释为char。

此外，我写的试图克服这个问题的转换器没有被调用。

Character

转换器注册如下：

public class CharToStringConvertor implements Converter<Character,String>{

    @Override
    public String convert(Character source) {
        return String.valueOf(source);
    }

}

public class StringToCharConverter implements Converter<String,Character> {

    @Override
    public Character convert(String source) {
        return source.toCharArray()[0];
    }

}

其他转换器按预期注册为调用，但未调用CharToString，反之亦然。
