我使用jOOQ 3.8.4和Postgres 9.5。 我有一个复杂的架构。实际上，当我做一个简单的选择时，比如：
create.selectFrom(ARTICLE_VIEW)
.orderBy(ARTICLE_VIEW.AV_CREATION_DATE
.desc()).limit(4).fetch();
我明白了：
java.lang.StackOverflowError
org.jooq.Converters$1.<init>(Converters.java:67)
org.jooq.Converters.identity(Converters.java:67)
org.jooq.impl.DefaultBinding.pgFromString(DefaultBinding.java:2041)
org.jooq.impl.DefaultBinding.pgFromString(DefaultBinding.java:2130)
org.jooq.impl.DefaultBinding.pgFromString(DefaultBinding.java:2041)
org.jooq.impl.DefaultBinding.pgFromString(DefaultBinding.java:2130)
org.jooq.impl.DefaultBinding.pgFromString(DefaultBinding.java:2041)
以及更多（有趣，这是我的第一个StackOverflowException）！
我激活了DEBUG日志记录模式，我复制了select并在PGAdmin中执行它。有用。 jOOQ应该有问题，但我不知道如何提供有用的信息。 发布我使用的模式将是疯狂的，它需要几十个表。有关如何进行的任何提示？

问题的可能来源
我按照Andrew Rueckert的链接进行了调试，但似乎问题出在jOOQ中。它无法正确处理类型内的类型。
该视图包含一个PostgreSQL类型的ArticleSimpleTypeRecord。它内部有一个类型。
在课程DefaultBinding中执行的步骤是：
使用pgFromString的默认转换器调用方法ArticleSimpleTypeRecord。这意味着要调用以下指令：
else if（Record.class.isAssignableFrom（type））{ return（T）pgNewRecord（type，null，string）; }
方法pgNewRecord尝试通过调用以下方法从给定对象创建记录：
public Record operate(Record record) {
List<String> values = PostgresUtils.toPGObject(object.toString());
Row row = record.fieldsRow();
for (int i = 0; i < row.size(); i++) {
pgSetValue(record, row.field(i), values.get(i));
}
return record;
}
将使用方法pgSetValue和object中的值将值设置到记录中。
当设置json值的值时，jOOQ调用方法pgSetValue(Record record, Field<T> field, String value)，该方法使用该字段的转换器调用方法pgFromString（即{{3 }}）。问题出在方法pgFromString中。
在pgFromString内，第Class<T> type = converter.toType()行返回com.google.gson.JsonElement，其未被任何默认值绑定，因此它会转到行：
else {
Converter<Object, T> c = (Converter<Object, T>) converter;
return c.from(pgFromString(c.fromType(), string));
}
问题出现了，因为json转换器应该将值转换为从pgFromString(c.fromType(), string)返回的对象开始的json，但是因为c.fromType()返回Object并且没有默认绑定对于jOOQ中的对象再次出现在默认情况下，并且一次又一次，我们有StackOverflowException。
我查看了该类中的更改，似乎当前的主人已经解决了这个问题。现在有：
else if (type == Object.class) {
return (T) string;
}
然后，我必须等待下一个jOOQ次要版本。我希望很快就会到来。

您是否为JsonElement注册了自定义绑定？我们也使用Gson类型，并且必须执行以下操作：
