生成器在重新绑定时抛出异常
Generator threw an exception while rebinding
我开发 GPS 监控系统的前端。我需要添加新功能 - 地理围栏。我已经创建了地理围栏模型及其 PropertyAccess 接口。
当我编译项目时出现错误：
这是地理围栏的模型：
public class Geofence extends JavaScriptObject {
protected Geofence() {}
public final native int getId() /*-{ return this.id; }-*/;
public final native String getName() /*-{ return this.name; }-*/;
public final native String getDescription() /*-{ return this.description; }-*/;
public final native Type getType() /*-{ return this.type; }-*/;
public final native Coordinate[] getCoordinates() /*-{ return this.coordinates; }-*/;
public final native double getRadius() /*-{ return this.radius; }-*/;
public final native int getUserId() /*-{ return this.userId; }-*/;
public final native void setId(int id) /*-{ this.id = id; }-*/;
public final native void setName(String name) /*-{ this.name = name; }-*/;
public final native void setDescription(String description) /*-{ this.description = description; }-*/;
public final native void setType(Type type) /*-{ this.type = type; }-*/;
public final native void setCoordinates(Coordinate[] coordinates) /*-{ this.coordinates = coordinates; }-*/;
public final native void setRadius(double radius) /*-{ this.radius = radius; }-*/;
public final native void setUserId(int userId) /*-{ this.userId = userId; }-*/;
public final String getEmpty() {
return "";
}
}
以及访问其属性的接口：
public interface GeofenceProperties extends PropertyAccess<Geofence> {
@Editor.Path("id")
ModelKeyProvider<Geofence> key();
ValueProvider<Geofence, Integer> id();
ValueProvider<Geofence, String> name();
ValueProvider<Geofence, String> description();
ValueProvider<Geofence, Coordinate[]> coordinates();
ValueProvider<Geofence, Double> radius();
ValueProvider<Geofence, Integer> userId();
ValueProvider<Geofence, String> empty();
}

来自ValueProviderCreator.java：
private boolean typesMatch(JClassType a, JType b) {
if (b.isPrimitive() != null) {
return a.getQualifiedSourceName().equals(b.isPrimitive().getQualifiedBoxedSourceName());
} else {
assert b.isClassOrInterface() != null;
return b.isClassOrInterface().isAssignableTo(a);
}
}
这段代码（我实际上是几年前写的，但我今天不为 Sencha 工作）假定您的 bean 属性 中的类型是原始类型或对象（或接口） .在 GWT 中，显然这排除了使用数组的可能性。来自 GWT 的 JArrayType：
public JClassType isClass() {
// intentional null
return null;
}
您需要提交 GXT 本身的错误才能更改此设置。但是，无论如何，您的代码在此之后可能无法正常工作（几乎可以肯定这是 中问题的根源，您的另一个问题）：
您不能让 JavaScript 对象的属性为非 JavaScript 类型。 GWT 生成的数组 几乎 看起来像 js 数组，但会丢失重要的类型细节，并且 java.util.List 根本不起作用。
相反，将 getCoordinates 更改为 return JsArray<Coordinate>。

但是当我改变
Coordinate[]
到
List<Coordinate>
一切正常。我哪里做错了？
com.sencha.gxt.data.rebind.PropertyAccessGenerator [ERROR] Generator 'com.sencha.gxt.data.rebind.PropertyAccessGenerator' threw an exception while rebinding 'org.bitbucket.treklab.client.model.GeofenceProperties' java.lang.NullPointerException at com.sencha.gxt.data.rebind.ValueProviderCreator.typesMatch(ValueProviderCreator.java:315)...
来自ValueProviderCreator.java：
private boolean typesMatch(JClassType a, JType b) {
if (b.isPrimitive() != null) {
return a.getQualifiedSourceName().equals(b.isPrimitive().getQualifiedBoxedSourceName());
} else {
assert b.isClassOrInterface() != null;
return b.isClassOrInterface().isAssignableTo(a);
}
}
这段代码（我实际上是几年前写的，但我今天不为 Sencha 工作）假定您的 bean 属性 中的类型是原始类型或对象（或接口） .在 GWT 中，显然这排除了使用数组的可能性。来自 GWT 的 JArrayType：
public JClassType isClass() {
// intentional null
return null;
}
您需要提交 GXT 本身的错误才能更改此设置。但是，无论如何，您的代码在此之后可能无法正常工作（几乎可以肯定这是
您不能让 JavaScript 对象的属性为非 JavaScript 类型。 GWT 生成的数组 几乎 看起来像 js 数组，但会丢失重要的类型细节，并且 java.util.List 根本不起作用。
相反，将 getCoordinates 更改为 return JsArray<Coordinate>。
