这个错误的解决方案： JsonIgnoreProperties({"hibernateLazyInitializer","handler"})//添加这一行
@Entity
@Table(name = "tbl_user")//可以省略 public class User {
[@Id](https://my.oschina.net/u/3451001)@GeneratedValue(strategy = GenerationType.IDENTITY)
private Integer id;
@Column(name = "last_name",length = 50)
private String lastName;
@Column //省略的写法
private String email;

34-TypeError: BoxSizer.AddSpacer(): argument 1 has unexpected type ''tuple''
TypeError: BoxSizer.AddSpacer(): argument 1 has unexpected type ''tuple''
这个错误很烦，折腾了好久；
原因有二：
1.因为它现在只能有一个参数了：
请看
2.因为你可能使用老版的wxFormBuilder产生的，而如果用新版的这会是：
bSizer1.Add( ( 0, 0), 1, wx.EXPAND, 5 )
新版下载链接：https://ci.appveyor.com/api/projects/jhasse/wxformbuilder-461d5/artifacts/wxFormBuilder_win32.zip?branch=master
不要在官网直接下载，感觉那个根本没跟新，跟新的已经放到了github上

Attempted to serialize java.lang.Class: org.hibernate.proxy.HibernateProxy. Forgot to register a ...
当我们使用gson 转对象时,并且这个对象中有一些属性是懒加载时如
@Entity
@Table(name = "user")
public class User {
@Id
@Column(columnDefinition="varchar(255)")
@GeneratedValue(generator="idGenerator")
@GenericGenerator(name="idGenerator", strategy="uuid")
private String userId;
private String userName;
private String nickName;
private String passWord;
private String phoneNumber;
@ManyToOne(cascade = {CascadeType.ALL},optional = true,fetch = FetchType.LAZY)
@JoinColumn(name = "enterprise_Id")
private EnterpriseInfo enterpriseInfo;
}会出现Attempted to serialize java.lang.Class: org.hibernate.proxy.HibernateProxy. Forgot to register a type adapter?
原因是:
hibernate采取懒加载的方式查询数据库,也就是只有用到了才去查真正的数据,用不到的话只是返回一个代理对象,gson识别不了代理对象,所以没法转换.
解决办法:
1.新建一个类,并继承TypeAdapter
import com.google.gson.Gson;
import com.google.gson.TypeAdapter;
import com.google.gson.TypeAdapterFactory;
import com.google.gson.reflect.TypeToken;
import com.google.gson.stream.JsonReader;
import com.google.gson.stream.JsonWriter;
import org.hibernate.Hibernate;
import org.hibernate.proxy.HibernateProxy;
import java.io.IOException;
/**
* @ClassName HibernateProxyTypeAdapter
* @Description 解决gson转换中对象有懒加载情况报错:
* @Author PC
* @Date 2018/10/29 10:23
**/
public class HibernateProxyTypeAdapter extends TypeAdapter<HibernateProxy> {
public static final TypeAdapterFactory FACTORY = new TypeAdapterFactory() {
@Override
public <T> TypeAdapter<T> create(Gson gson, TypeToken<T> typeToken) {
return (HibernateProxy.class.isAssignableFrom(typeToken.getRawType())? (TypeAdapter) new HibernateProxyTypeAdapter(gson):null);
}
};
private final Gson context;
private HibernateProxyTypeAdapter(Gson gson){
this.context = gson;
}
@Override
public void write(JsonWriter jsonWriter, HibernateProxy hibernateProxy) throws IOException {
if (hibernateProxy==null){
jsonWriter.nullValue();
return;
}
Class<?> baseType = Hibernate.getClass(hibernateProxy);
TypeAdapter delegate = context.getAdapter(TypeToken.get(baseType));
Object unproxiedValue = ((HibernateProxy) hibernateProxy).getHibernateLazyInitializer()
.getImplementation();
delegate.write(jsonWriter,unproxiedValue);
}
@Override
public HibernateProxy read(JsonReader jsonReader) throws IOException {
throw new UnsupportedOperationException("Not support");
}
}2.构建gson对象
Gson gson = new GsonBuilder().setDateFormat("yyyy-MM-dd")
.registerTypeAdapterFactory( HibernateProxyTypeAdapter.FACTORY).create() ; 3.完成.
参考别人的博客并加以整理.
Grails 2.4 + Hibernate 4 +可搜索的插件= ClassNotFoundException：org.hibernate.impl.SessionFactoryImpl
最近，我将一个简单的Grails应用程序与Searchable插件集成在一起。我发现，Searchable插件不适用于Hibernate 4库。
在这里您可以找到一个示例应用程序，其中仅包含干净的Grails 2.4应用程序，仅添加了Searchable插件-https:
//github.com/wololock/grails-searchable-
example
当我运行该应用程序时：
runtime ":hibernate4:4.3.5.5"
依赖关系，它不会启动并引发异常：
ClassNotFoundException: org.hibernate.impl.SessionFactoryImpl
我已经发现，在Hibernate4中，SessionFactoryImpl已移至org.hibernate.internal包中，并且Compass似乎在旧位置中查找此类：
2014-10-11 19:41:58,142 [localhost-startStop-1] ERROR context.GrailsContextLoaderListener - Error initializing the application: org/hibernate/impl/SessionFactoryImpl
Message: org/hibernate/impl/SessionFactoryImpl
Line | Method
->> 95 | injectLifecycle in org.compass.gps.device.hibernate.lifecycle.DefaultHibernateEntityLifecycleInjector
切换回：
runtime ":hibernate:3.6.10.17"
和改变
cache.region.factory_在DataSource.groovy中解决了该问题。
我的问题是： 是否可以在Hibernate 4中使用Searchable插件，或者我们必须等待或解决Compass /
Searchable源代码中的问题？您如何在Grails应用程序中处理该问题？谢谢您的提示。
HibernateProxy. Forgot to register a type adapter?
使用Gson转换Hibernate对象遇到一个问题，当对象的Lazy加载的，就会出现上面的错误。处理方式摘抄自网上，留存一份以后自己看。
/**
* This TypeAdapter unproxies Hibernate proxied objects, and serializes them
* through the registered (or default) TypeAdapter of the base class.
*/
public class HibernateProxyTypeAdapter extends TypeAdapter<HibernateProxy> {
public static final TypeAdapterFactory FACTORY = new TypeAdapterFactory() {
@Override
@SuppressWarnings("unchecked")
public <T> TypeAdapter<T> create(Gson gson, TypeToken<T> type) {
return (HibernateProxy.class.isAssignableFrom(type.getRawType()) ? (TypeAdapter<T>) new HibernateProxyTypeAdapter(gson) : null);
}
};
private final Gson context;
private HibernateProxyTypeAdapter(Gson context) {
this.context = context;
}
@Override
public HibernateProxy read(JsonReader in) throws IOException {
throw new UnsupportedOperationException("Not supported");
}
@SuppressWarnings({"rawtypes", "unchecked"})
@Override
public void write(JsonWriter out, HibernateProxy value) throws IOException {
if (value == null) {
out.nullValue();
return;
}
// Retrieve the original (not proxy) class
Class<?> baseType = Hibernate.getClass(value);
// Get the TypeAdapter of the original class, to delegate the serialization
TypeAdapter delegate = context.getAdapter(TypeToken.get(baseType));
// Get a filled instance of the original class
Object unproxiedValue = ((HibernateProxy) value).getHibernateLazyInitializer()
.getImplementation();
// Serialize the value
delegate.write(out, unproxiedValue);
}
}实现上面的类，然后就是使用：
GsonBuilder b = new GsonBuilder();
...
b.registerTypeAdapterFactory(HibernateProxyTypeAdapter.FACTORY);
...
Gson gson = b.create();解释，只是看不懂。
GSON contains a number of TypeAdapterFactory implementations, for various types (primitive types, common types like String or Date, lists, arrays...). Each factory is asked if it is able to serialize a certain Java type (the parameter to create is a TypeToken instead of a Class in order to capture possible information about generic types, which Class does not have). If the factory is able to serialize/deserialize a type, it responds with a TypeAdapter instance; otherwise it responds with null.
HibernateProxyTypeAdapter.FACTORY verifies whether type implements HibernateProxy; in that case, it returns an instance of HibernateProxyTypeAdapter for serialization. The write method is called when an actual object has to be serialized; the adapter extracts the original type of the underlying object, and asks GSON for the standard TypeAdapter for the original type, which generally is a ReflectiveTypeAdapter.
Then it retrieves an instance of the original class, instead of directly using the proxy. This is necessary because ReflectiveTypeAdapter accesses directly to fields, instead of using getters; accessing to the fields of a proxied object does not work, and is a classical Hibernate pitfall.
As a possible performance improvement, the delegate TypeAdapter should be acquired in the create method. I found out that calling getSuperclass() on the proxy Class appears to yield the original base class.
