我在解决<forcedType>
我生成的例程中用 PL/pgSQL 编写的存储函数的问题时遇到了问题。这个问题更具体地解决了我在这个问题中已经提出的问题,并且在这个问答中部分提供了答案。
这是我在 PL/pgSQL 中遇到问题的用户定义函数之一(我只显示一个,因为两个函数具有相同的 RETURN TYPE和INPUT 参数):
create or replace function public.get_order_by_order_id(o_id bigint) returns json as
$BODY$
DECLARE
finalJson json;
BEGIN
return finalJson;
END;
&BODY&
LANGUAGE 'plpgsql';
由于我使用的是 Maven,这些是我用来执行转换的 pom.xml 强制类型(如上面链接的 Q&A中):
<forcedType>
<userType>java.lang.String</userType>
<converter>
org.jooq.Converter.ofNullable(org.jooq.JSON.class, String.class, Object::toString, org.jooq.JSON::valueOf)
</converter>
<includeExpression>(?i:get_book_by_book_id|return_value)</includeExpression>
</forcedType>
<forcedType>
<userType>java.lang.Long</userType>
<converter>
org.jooq.Converter.ofNullable(Long.class, String.class, Object::toString, java.lang.Long::valueOf)
</converter>
<includeExpression>(?i:get_book_by_book_id\.b_id)</includeExpression>
</forcedType>
<forcedType>
<userType>java.lang.String</userType>
<converter>
org.jooq.Converter.ofNullable(org.jooq.JSON.class, String.class, Object::toString, org.jooq.JSON::valueOf)
</converter>
<includeExpression>(?i:get_order_by_order_id|return_value)</includeExpression>
</forcedType>
<forcedType>
<userType>java.lang.Long</userType>
<converter>
org.jooq.Converter.ofNullable(Long.class, String.class, Object::toString, java.lang.Long::valueOf)
</converter>
<includeExpression>(?i:get_order_by_order_id\.o_id)</includeExpression>
</forcedType>
当我在Project Exporer>Maven>Update Project中右键单击我的项目并选中“强制更新..”复选框时,我收到以下两个错误:
类型不匹配:无法从 Parameter < String > 转换为 Parameter < Long >
...这就是我生成的GetBookByBookId.java类代码的样子:
// This class is generated by jOOQ.
@SuppressWarnings({ "all", "unchecked", "rawtypes" })
public class GetBookByBookId extends AbstractRoutine<String> {
private static final long serialVersionUID = 1276724822;
// The parameter <code>public.get_book_by_book_id.RETURN_VALUE</code>.
public static final Parameter<String> RETURN_VALUE = Internal.createParameter("RETURN_VALUE", org.jooq.impl.SQLDataType.JSON, false, false, org.jooq.Converter.ofNullable(org.jooq.JSON.class, String.class, Object::toString, org.jooq.JSON::valueOf));
// The parameter <code>public.get_book_by_book_id.b_id</code>.
// Error is occuring AT NEXT LINE of code for value of "B_ID" variable !!!!!!!!!!
public static final Parameter<Long> B_ID = Internal.createParameter("b_id", org.jooq.impl.SQLDataType.BIGINT, false, false, org.jooq.Converter.ofNullable(Long.class, String.class, Object::toString, java.lang.Long::valueOf));
// Create a new routine call instance
public GetBookByBookId() {
super("get_book_by_book_id", Public.PUBLIC, org.jooq.impl.SQLDataType.JSON, org.jooq.Converter.ofNullable(org.jooq.JSON.class, String.class, Object::toString, org.jooq.JSON::valueOf));
setReturnParameter(RETURN_VALUE);
addInParameter(B_ID);
}
// Set the <code>b_id</code> parameter IN value to the routine
public void setBId(Long value) {
setValue(B_ID, value);
}
// Set the <code>b_id</code> parameter to the function to be used with a {@link org.jooq.Select} statement
public GetBookByBookId setBId(Field<Long> field) {
setField(B_ID, field);
return this;
}
}
将字符串值strParam传递给Long.valueOf( strParam )应该可以工作,但是在 jOOQ 中由于某种原因它不起作用。Java编译器不应该能够从org.jooq.Converter.ofNullable(Long.class, String.class, Object::toString, java.lang.Long::valueOf)
传入的代码中推断出它<converter>
......我是否缺少一些东西,究竟是什么?
非常感谢任何形式的帮助或建议。
